Overview

General considerations about GreenPower Android app.

Purpose

GreenPower reduces your device's battery usage by switching off wireless connections (Wi-Fi, Mobile Network, Bluetooth) when they are not used and controls the display brightness.
Basically the idea is: Why should the wireless connections be always on, emptying the battery, even when you don't use your device? Most people would answer: In order to get live notifications of new mails and other push data. Right, but in most cases you don't need to be notified the second you receive a new mail. Every few minutes is enough. So why not keep wireless switched off most of the time and turn it on regularly, briefly, to let applications receive their push data? This is what GreenPower does.
How much battery power GreenPower saves of course depends on how you use your device. In its default configuration, GreenPower will regularly turn wireless connectivity off for 15 minutes, then on for 1 minute, and so on. It will also keep wireless on if you are using the device (screen on) or if the device is connected to a power source. To avoid interrupting other application's connections, GreenPower will check to see if there is any incoming/outgoing traffic before switching wireless off. This default configuration can be changed in GreenPower settings.

Installation

Purchase & Refund

You can purchase GreenPower premium on Google Play. Please note that the purchasing and payment mechanisms are handled entirely by Google Play so if there are any issues (problems with your credit card, etc.), you should contact Google's support as we cannot deal with these ourselves. However, we can always cancel your order if you want to try placing another one.

As for most apps in Google Play, purchasing GreenPower involves a one-time payment only. There are no recurring charges, and subsequent updates will all be free.

Money-back guarantee

Google's policy of 15 minutes trial time is too short for an app of this type. Therefore we offer 24 hrs trial time with a money-back guarantee if it does not work as you expected on your device. Just send a refund request through our contact email to get your money back.

Download

You can download GreenPower Free and GreenPower Premium from Google Play or from alternative markets like AndroidPit or Amazon.

Once in a while, a download may fail. This is not something we can do anything about, as it is handled entirely by Google Play. However, please remember that once you have been charged, you can always download again later. You will not need to pay again. This ensures you will eventually get the app you have paid for, even when there are temporary connection problems.

For GreenPower Premium, please note that on Google Play, your license to use the software is linked to your Google account. So if you change devices, for instance, you should use the same Google account again if you wish to re-use apps you previously purchased. Also, please note that once you have purchased GreenPower premium with a specific Google account, you can download it again in future as many times as you want.

Installation

As with all other Android apps, the installation of GreenPower is straightforward and is automatically included in the process of downloading from Google Play.

Installation on SD card

GreenPower should not be installed on the SD card. As with all apps that use background services, installation on the SD card is not recommended.

If you install it on the SD card anyway, the following limitations will apply:
• GreenPower won't start at boot.
• GreenPower will be shut down automatically when the SD card is unmounted.
• GreenPower will not be automatically restarted when SD card is mounted again.

Starting up for the first time

When starting up for the first time or after an upgrade, GreenPower will show the following screens.

License agreement

After being installed for the first time, our license agreement will be displayed. You have to accept it to use GreenPower.

Release notes

After each app's upgrade, the release notes are shown, displaying what is new in this release, as well as the history from previous releases.

As with any other dialog in GreenPower, the release notes screen can be closed by pressing the back key.

Main screen

After the release notes screen, GreenPower will show its main screen. This is the screen that appears at each startup of the application and that displays a summary of the app's status and settings. This is described in more detail later in the «Main screen» section of the «GUI» chapter.

In most cases, the default settings should be fine. If you don't need to change the default settings, you can just leave this page (back or home button), and you're ready to go. However, we recommend that you review the configuration chapter to familiarize yourself with the different options so you can customize GreenPower to your own requirements.

Uninstallation

Like any other Android app, GreenPower can be uninstalled from the device settings in the Applications section.

Notification title

Notification description

Wi-Fi has been manually disabled

Either you or the system has turned Wi-Fi OFF. As a result, GreenPower has unchecked the «Manage Wi-Fi» setting in order not to override your action by turning Wi-Fi ON again. You can resume normal GreenPower operation by either turning Wi-Fi ON manually or checking the «Manage Wi-Fi» setting.

Note that this notification can only appear if you have the setting «Wi-Fi manual toggle» in «Advanced Wi-Fi settings» set to «Disable Wi-Fi management».

Mobile Network management is disabled

The GreenPower setting «Manage Mobile Network» is deselected. This means that GreenPower does not switch the Mobile Network connection ON and OFF automatically as it should do. To strike the best balance between saving power and online connectivity, it is best to let GreenPower handle this. You can do this by checking the «Manage Mobile Network» checkbox in GreenPower's settings.

If you chose on purpose to not have GreenPower manage your mobile network, you can remove this notifications in the «Notifications» settings section.

Wi-Fi management is disabled.

The GreenPower setting «Manage Wi-Fi» is unselected. This means that GreenPower doesn't switch ON and OFF the Wi-Fi connection automatically as it should do. In order to have the best balance between saving power and being online, please let GreenPower handle this and check «Manage Wi-Fi» checkbox in GreenPower settings.

If you chose on purpose to not have GreenPower manage your Wi-Fi, you can remove this notification in the «Notifications» settings section.

Airplane mode is ON.

Airplane mode is turned ON. GreenPower won't turn wireless ON as long as airplane mode is ON. This notification won't appear if the Wi-Fi setting «Allow in airplane mode» is checked.

Screen unlock couldn't be detected.

GreenPower couldn't detect the screen being unlocked on your device. Therefore wireless hasn't been turned back on until now. You should uncheck the setting «Toggle if screen unlocked» (day and night mode) to prevent this occurring. Usually, this problem is caused by 3rd party screen locker or home apps. If the problem persists, please contact us.

No valid license.

You don't seem to have a valid license to use GreenPower. You can try checking the license again by stopping and restarting GreenPower. The license to use GreenPower is linked to your gmail account. If you still get this notification when you are sure you have purchased GreenPower using the account you are currently using, please contact us.

Neither Wi-Fi nor Mobile Network is being managed.

Both GreenPower settings «Manage Wi-Fi» and «Manage Mobile Network» are unchecked. You should check at least one of the two or GreenPower will not do anything, unless you are using it for Bluetooth management.

GreenPower paused.

GreenPower is paused. You can resume with either the menu or the widget.

Mobile Network has been manually disabled.

You or the system has turned Mobile Network OFF. As a consequence, GreenPower has unchecked the «Manage Mobile Network» OFF in order not to override your action by turning the Mobile Network ON again. You can resume normal GreenPower operation by either turning Mobile Network ON manually or checking the «Manage Mobile Network» setting. Alternatively, you can change the «Mobile Network manual toggle» setting.

Note that this notification can only appear if you have the setting «Mobile Network manual toggle» in «Mobile Network settings» set to «Stop managing Mobile Network».

Widget

Installing the widget

Using the widget

The Widget provides a shortcut to pause or restore GreenPower. It operates in simple toggle fashion to pause or restore the app.

end faq

Settings

GreenPower's default settings should be fine for most people. If you want to use some features (mainly premium features), however, you should enable them as they are not on by default. Those features are:

Bluetooth management Apps management Autosync management Night mode Location-based Wi-Fi

In addition, it is recommended that you have a look at other existing settings as they may allow you to do more than you expected. All settings are detailed below.

Wi-Fi Settings

Defines settings that are specific to the Wi-Fi management.

Setting name

Type

Description

Values

Manage Wi-Fi

Checkbox

Defines whether GreenPower shall regularly toggle your Wi-Fi on/off or leave it untouched.

Checked (Recommended): GreenPower will regularly toggle your Wi-Fi on/off according to the settings defined in other sections («Wi-Fi settings», «Common settings» and «Day & Night settings»).

 

Unchecked: GreenPower will not toggle your Wi-Fi on/off under any circumstances.

Wi-Fi screen OFF policy

Listbox

When Wi-Fi is being managed, the default behavior when the screen is OFF is for GreenPower to regularly toggle Wi-Fi on/off. However, with this setting you can choose to keep the Wi-Fi constantly ON or OFF when the screen is OFF.

Keep Wi-Fi ON if connected to a network (recommended for Samsung devices): When the screen is turned OFF, Wi-Fi will stay ON if it is connected to a Wi-Fi network and will be turned OFF otherwise. No regular toggling ON/OFF will occur.

 

Keep Wi-Fi OFF: When the screen is turned OFF, Wi-Fi will stay OFF. No regular toggling ON/OFF will occur.

 

Toggle Wi-Fi regularly (recommended for non-Samsung devices): GreenPower will regularly toggle ON/OFF your Wi-Fi according to the settings defined in other sections («Wi-Fi settings», «Common settings» and «Day & Night settings»). Note that on some Samsung devices, turning the Wi-Fi ON while the screen is OFF may cause the device to freeze. It is therefore recommended that you do not use this setting if you encounter problems of this type.

Location-based Wi-Fi

Enable location-based Wi-Fi

Checkbox

Activate Location-based Wi-Fi. Location-based Wi-Fi is a smart way of managing your Wi-Fi. It monitors the device's location and only turns Wi-Fi ON when the device is close to a known Wi-Fi network.

The first time you want to connect to a specific Wi-Fi network, you would manually turn the Wi-Fi ON. GreenPower will then try to locate the network. If it succeeds, it will then add the Wi-Fi network to its list of known networks, storing its name and location.

Next times, when GreenPower needs to turn ON Wi-Fi (for instance when screen gets turned ON or via regular toggling), it would first check the device location and would only turn Wi-Fi ON if it is near a previously registered Wi-Fi network.

The location only uses the coarse location service, and no GPS, to save battery. It requires that "Google location service" is enabled in your device's settings.

Checked: Location-based Wi-Fi is used.

 

Unchecked: Location-based Wi-Fi is not used.

Accuracy-circle multiplier

Listbox

The location-based Wi-Fi only uses the coarse location service, and can therefore be rather inaccurate in rural areas with only few base stations. This settings allows to increase the tolerance of the location service accuracy so that it would toggle Wi-Fi ON a bit further from the actual Wi-Fi network.

x 1: Normal accuracy as reported by the device's location service. To be used in urban areas with many base stations.

 

x 1.5: 50% Increased accuracy tolerance.

x 2: Doubled accuracy tolerance.

 

x 3: Maximum tolerance. To be used in rural areas with only a few base stations that do not permit a high level of location accuracy.

Group by name

Checkbox

Groups the Wi-Fi networks by name in the list of known networks, instead of grouping them by SSID. This is useful for Wi-Fi networks that have many access points (each with its own SSID). This is only used to configure the way the list of known Wi-Fi networks is displayed and has no effect on the way location-based Wi-Fi works.

Checked: Group Wi-Fi networks by name in the known Wi-Fi networks list.

 

Unchecked: Group Wi-Fi networks by SSID in the known Wi-Fi networks list.

Wi-Fi networks with known location

List

Displays the list of Wi-Fi networks with a known location. The networks are added automatically when the device successfully connects to the Wi-Fi network the first time, if the device's location could be determined. The network name, SSID, location and location accuracy are stored. The list displays the current distance to the network.

You can remove one of the networks in the list by pressing it and clicking OK.

 

-

Wi-Fi manual toggle

List

Defines what GreenPower should do if you manually turn Wi-Fi OFF. Because Wi-Fi should normally be turned ON/OFF by GreenPower, it needs to know what to do if you override it.

 

Disable Wi-Fi Management: «Manage Wi-Fi» setting is unchecked automatically so that GreenPower stops managing Wi-Fi completely until either you check «Manage Wi-Fi» again or enable Wi-Fi manually once more.

 

Disable Wi-Fi Management until screen OFF (recommended): GreenPower stops managing Wi-Fi – no longer turning it ON/OFF - but only until the next screen OFF. After that, normal Wi-Fi management resumes.

 

Force Wi-Fi on: Wi-Fi is forced back ON and Wi-Fi management remains untouched.

Wi-Fi timeout

Checkbox

Activate the Wi-Fi connection timeout check. The timeout is started when Wi-Fi is turned ON by GreenPower. After the timeout, GreenPower checks to see whether Wi-Fi could successfully connect to a Wi-Fi access point. If not, Wi-Fi is disconnected until the next cycle.

Allows a good balance between two situations: Being at home where Wi-Fi is connected immediately, and being outside where Wi-Fi tries to connect but, to save battery power, doesn't stay on unnecessarily.

It is recommended to have this option checked unless you experience the device freezing up, which may happening on some models.

Checked (recommended): Timeout used.

 

Unchecked: Timeout not used.

Timeout duration

List

Timeout duration used by the «Wi-Fi timeout» setting.

Number of seconds

Low signal check

Checkbox

Activate the Wi-Fi low signal check. The check is performed when a successful connection is made to a Wi-Fi access point. At this stage, if the signal level is too low, the Wi-Fi is disconnected to save battery power.

It is recommended to have this option checked unless you experience the device freezing up, which may happening on some models.

Checked (recommended): Signal check performed.

 

Unchecked: Signal check not performed.

Wi-Fi signal threshold

List

Signal strength threshold used by the «Low signal check».

Percentage of signal strength.

Allow in flight mode

Checkbox

By default GreenPower won't turn Wi-Fi ON if the device is in airplane mode. However, some people use airplane mode in areas without cell coverage, for example, and may still want to use Wi-Fi. Some airlines have also recently begun to offer Wi-Fi on board.

Checked: Wi-Fi will be normally toggled ON/OFF when the device is in airplane mode.

 

Unchecked (recommended): Wi-Fi won't be turned ON by GreenPower as long as the device is in airplane mode.

Override Wi-Fi sleep policy

Checkbox

Android's default Wi-Fi sleep policy is not very smart. When activated, it will make Wi-Fi sleep after a while when the screen is off. This would of course save battery power, but also prevents push data and mails being received. It is best to deactivate this and let GreenPower handle it instead.

Checked (recommended): Force the device's Wi-Fi sleep policy off.

 

Unchecked: Don't change the device's Wi-Fi sleep policy.

Mobile Network settings

Manage Mobile Network

Checkbox

Defines whether GreenPower shall regularly toggle your Mobile Network on/off or leave it untouched.

Checked: GreenPower will regularly toggle your Mobile Network on/off according to the settings defined in other sections («Mobile Network settings», «Common settings» and «Day & Night settings»).

 

Unchecked: GreenPower will not toggle your Mobile Network on/off under any circumstances.

Mobile Network manual toggle

List

Defines what GreenPower should do if you manually turn the Mobile Network OFF. Because the Mobile Network should normally be turned ON/OFF by GreenPower, it needs to know what to do if you override it.

 

Stop managing Mobile Network: «Manage Mobile Network» setting is automatically unchecked so that GreenPower stops managing the Mobile Network completely until either you check «Manage Mobile Network» again or enable Mobile Network manually again.

 

Stop managing until screen OFF (recommended): GreenPower stops managing the Mobile Network– no longer turning it ON/OFF - but only until next screen OFF. After that, normal management resumes.

Mobile Network toggling method

List

Toggling of Mobile Data on Android is normally not possible for apps, so there is no perfectly reliable way of doing this. In most cases it can be achieved using a so-called «internal API». In some cases this may not work well (mainly for 4G LTE devices), so the backup solution is to use the not-so-clean «APN renaming» method.

In general, you should not touch this setting unless you observe your Mobile Data not being properly toggled by GreenPower.

Use internal API (recommended): Cleanest way, working in most cases.

 

Use APN renaming: For cases where other choices do not work. Mainly for 4G LTE devices.

Bluetooth settings

Manage Bluetooth

Checkbox

Defines whether GreenPower shall regularly toggle Bluetooth connectivity on/off.

Please understand that Bluetooth management differs in important ways from Wi-Fi and Mobile Network management:

For Wi-Fi and Mobile Network management, there are constant cycles of turning OFF (to save battery power) and turning ON (to get push data as mails, or when the screen is turned ON for instance).

For Bluetooth, it is not advisable to toggle it ON regularly. Because there is no data to fetch, it doesn't make sense to try to connect to Bluetooth devices regularly.

Instead, Bluetooth management aims at automating the turning ON of Bluetooth in some situations, as well as automating the turning OFF of Bluetooth in other situations. See below. But in some cases, it is still best for you to turn Bluetooth ON manually.

Checked: GreenPower will toggle your Mobile Network on/off according to the settings defined in the section «Bluetooth settings».

 

Unchecked: GreenPower will not toggle on/off your Bluetooth under any circumstances.

Auto turn OFF

Bluetooth check interval

List

When Bluetooth is ON, this activate the regular check to see if it makes sense to keep it ON or if it can be turned OFF to save battery.

This checks to see whether the device is connected to another Bluetooth device, or if there are other devices or known devices in range, depending on the «Turn OFF policy» setting.

Number of minutes.

Turn OFF policy

List

Defines under what condition Bluetooth should be turned OFF when checked, depending on the devices connected or in range.

Turn OFF if no device in range: Let the device search for Bluetooth devices in range. If none is found, Bluetooth is turned OFF.

 

Turn OFF if no paired device in range: Let the device search for already known (paired) devices in range. If none is found, Bluetooth is turned OFF.

 

Turn OFF if not connected to a device (recommended): If the device is currently not connected to any other Bluetooth device, then Bluetooth is turned OFF: Note that this is the most efficient energy-saving option as it does not require any extra scanning for Bluetooth devices.

OFF when power disconnected

Checkbox

Turn OFF Bluetooth at once when the device is disconnected from a power source. It is especially useful if you use Bluetooth in your car to disable Bluetooth when unplugging the device and leaving the car.

Checked: Turns Bluetooth OFF at once when the power is disconnected.

 

Unchecked: Doesn't turn OFF Bluetooth when power is disconnected.

OFF at end of call

Checkbox

Turn OFF Bluetooth at once when a phone call ends (both incoming or outgoing call). Only applies if Bluetooth was previously turned ON by GreenPower at the beginning of the call.

Checked: Turns OFF Bluetooth immediately when a call ends.

 

Unchecked: Doesn't turn OFF Bluetooth at the end of a call.

Auto turn ON

Screen toggle policy

List

Defines whether Bluetooth should be turned ON when the screen is turned ON, unlocked, or whether it should be left as it is.

Note that if Bluetooth is turned ON, it will stay ON until it is turned OFF manually or by the policy defined in the paragraph «Auto turn OFF».

Turn ON if screen is turned ON: As soon as screen is turned ON, Bluetooth is turned ON.

 

Turned ON if screen is unlocked: As soon as screen is unlocked, Bluetooth is turned ON.

 

Don't turn ON if screen turned ON: When screen is turned ON or unlocked, Bluetooth is not affected and remains as it is.

Keep if power ON

Checkbox

Turn and Keep Bluetooth ON when the device is connected to a power source.

Checked: Turns ON Bluetooth when power is connected.

 

Checked: Does not turn ON Bluetooth when power is connected.

ON when call received

Checkbox

Turns Bluetooth ON when a call is received. Bluetooth is turned ON as soon as the phone rings, without waiting for you to answer. Useful when using Bluetooth headset.

Note that after the call or if you don't answer, Bluetooth will stay ON until it is turned OFF manually or by the policy defined in the paragraph «Auto turn OFF».

Checked: Turns ON Bluetooth when a call is received (when phone is ringing).

 

Unchecked: Doesn't turn ON Bluetooth when a call is received.

ON when call made

Checkbox

Turns Bluetooth ON when an outgoing call is made. Bluetooth is turned ON as soon as the phone rings, without waiting for the person called to answer. Useful when using Bluetooth headset.

Note that after the call or if the call is not answered, Bluetooth will stay ON until it is turned OFF manually or by the policy defined in the paragraph «Auto turn OFF».

Checked: Turns ON Bluetooth when an outgoing call is made.

 

Unchecked: Doesn't turn ON Bluetooth when an outgoing call is made.

Auto connect

Checkbox

Automatically connects to paired (known) devices when Bluetooth is turned ON on your device.

When turning ON Bluetooth, some device models automatically connect to known paired devices; others don't. This is manufacturer-dependent. This setting therefore allows uniform automatic connection behavior on all devices.

Checked: Automatically connects to known paired device when Bluetooth is turned on on this device.

 

Unchecked: Does not guarantee automatic connection to known paired device when Bluetooth is turned on on this device. However, some device models may still automatically connect.

Apps settings

Defines settings related to apps whitelist and apps blacklist features.

 

Active apps

Whitelist and Blacklist rely on the concept of apps being active or not. The Android definition of an app being active is that it is visible (in the foreground) or doing something that is directly perceptible to the user like playing music. However it is at the OS discretion to decide whether an app is active or not. If you encounter that despite some app is streaming music the Wi-Fi / data is cut, then leave the app on the foreground so that it is perceived by the OS as active.

Apps whitelist

The apps whitelist feature allows you to define a list of apps that should prevent GreenPower from turning Wi-Fi / data off.

When it's time for GreenPower to turn Wi-Fi and/or data off, it will check to see whether a whitelisted app is active. If so, GreenPower won't turn Wi-Fi / data off.

This feature is mainly useful for music streaming apps (Pandora, Spotify, TuneIn) to avoid the music being interrupted when the screen is turned off.

Don't overuse the option by adding apps that are constantly active, like system apps or widgets, or Wi-Fi / data won't be turned off any more.

Apps blacklist

The apps blacklist feature allows you to define a list of apps that should force GreenPower to turn Wi-Fi / data off whenever they are active. It is mainly useful when running fullscreen games or videos that don't require an internet connection.

Don't overuse this option by adding apps that are constantly active, like system apps or widgets, or Wi-Fi / data won't be turned on any more.

Lists priority

Checkbox

If apps from both the whitelist and blacklist are active, defines which ones takes precedence.

Whitelist: If apps from both the whitelist and blacklist are active, the whitelist takes precedence, which meaning the Wi-Fi / data will stay ON.

 

Blacklist: If apps from both the whitelist and blacklist are active, the blacklist takes precedence, meaning the Wi-Fi / data will stay OFF.

Apps check frequency

List

GreenPower needs to check regularly to see which apps are running. Checking more often provides better reactivity: turning off data more quickly when a blacklisted app is launched, or restoring connectivity when it exits. But this uses a bit more CPU power.

High frequency: Check frequently. Best reactivity but highest CPU usage.

 

Medium frequency: Best balance between reactivity and CPU usage.

Low frequency: Lowest CPU usage, but lower reactivity.

Accounts sync settings

Defines settings related to management of accounts syncing. The accounts are listed in your device in the "settings > accounts" section. Android doesn’t offer much control by default as you can just globally enable or disable accounts syncing. GreenPower offers much more finely-grained control. The basic idea is that since GreenPower turns Wi-Fi / data off most of the time, there is no reason for the account syncing to be ON, as it would fail. Instead, GreenPower can turn syncing ON when it turns Wi-Fi / data ON, ensuring that emails or other messages will be fetched exactly when the network is available. You can also specify if you want the syncing to be run less often than at each connection time.

Setting name

Type

Description

Values

Sync accounts

Checkbox

Defines whether GreenPower should manage the way accounts syncing is done on the device.

Checked (recommended): Enable the management of accounts syncing by GreenPower.

 

Unchecked: Disable the management of accounts syncing by GreenPower.

Sync on schedule

Checkbox

Defines whether GreenPower should perform a syncing of the accounts each time connectivity is turned ON through the regular toggling of Wi-Fi and data. Some restrictions may apply depending on the other settings below.

Checked (recommended): Sync accounts each time Wi-Fi / data is switched ON via regular toggling. Some restrictions may apply depending on the other settings below.

 

Unchecked: Don't sync the accounts when Wi-Fi / data is switched ON via regular toggling.

Sync when screen turned ON

Checkbox

Defines whether GreenPower should perform a syncing of the accounts when Wi-Fi / data is turned ON after screen is turned ON or unlocked. Some restrictions may apply depending on the other settings below.

Checked (recommended): Sync the accounts when Wi-Fi / data is switched ON after screen is turned ON or unlocked. Some restrictions may apply depending on the other settings below.

 

Unchecked: Don't sync the accounts when Wi-Fi / data is switched ON after screen is turned ON or unlocked.

Delay sync at screen ON

Checkbox

To decrease CPU usage, this setting allows the syncing to be delayed for a few seconds after screen is turned ON.

Checked (recommended): Delays the syncing by about 5 seconds after Wi-Fi / data is enabled.

 

Unchecked: Don't delay the syncing and instead sync accounts immediately once Wi-Fi / data is switched ON after the screen is turned ON. Some restrictions may apply depending on the other settings below.

Avoid unwanted autosync

Checkbox

The settings above allow you to define when GreenPower will force the syncing. But if the device's main setting "enable autosync" is ON, the device itself may choose to run syncing at other times. Therefore you can specify here that when GreenPower is not explicitly forcing a syncing, it will keep the device's main setting switched off to prevent the device from running other syncing (which would fail anyway if the network is off).

Checked (recommended): Keep device's main autosync setting switched off.

 

Unchecked: Keep device's main autosync setting switched on. The device may run syncing at any time.

Sync only on Wi-Fi

Checkbox

Syncing can result in a significant amount of data being transferred. Therefore if you don't have an appropriate data plan, it is best to sync only on Wi-Fi.

Checked (recommended): Only run syncing when Wi-Fi is connected.

 

Unchecked: Run syncing both on Wi-Fi and mobile network.

Sync minimum delay

List

Instead of running a sync every time Wi-Fi / data is turned ON, you can define here a minimum time between each syncing.

The minimum delay in seconds between two syncings.

Autosync when charging

Checkbox

If the device is charging, you can choose to keep the device's austosync setting ON so that the device may sync at any time.

Checked (recommended): Keep device's main autosync enabled when the device is charging.

 

Unchecked: Keep device's main autosync disabled when the device is charging.

Traffic settings

Defines settings involved in checking Wi-Fi / data traffic.

Check data traffic

Checkbox

Defines whether GreenPower should ensure there is no traffic or low traffic before it can turn OFF wireless.

Checked (recommended): If there is traffic when GreenPower tries to turn wireless OFF (Wi-Fi and/or Mobile Network depending on which is managed), it will wait and try again later.

 

Unchecked: GreenPower turns wireless OFF (Wi-Fi and/or Mobile Network depending on which is managed) as soon as it needs to, regardless of traffic.

Traffic settings

 

Data traffic threshold

List

Defines the data threshold under which GreenPower can turn data OFF when needed.

Threshold in kBytes/s.

Traffic check duration

List

The traffic threshold is an average measured over a given period of time. For optimal energy-saving, a short period is best as it allows data to be turned OFF earlier. For fewer side effects, longer periods are best as some applications (especially streaming apps like Spotify or Pandora) receive data in bursts rather than regularly.

Duration in seconds.

Day & Night settings

Day mode settings

Those settings apply to day mode only (outside of the time range defined in the night mode), or all day long if night mode is not enabled.
