Disable power save android

Tutorial: Turning off power saving on Android phones

In last couple of years, Android phone manufacturers have been concentrating improving the battery life of their phones. In consequence most new phones limit 3rd party apps’ access to the internal GPS when the app runs in background. Some phones will even stop applications from running in the background.

The intent is good, but all this has effect on apps like RaceChrono that collect data – even when the display is turned off and the app has gone to background.

Most phones have settings to turn off the power saving measures. Here’s the list of preferred settings for different phones, to allow recording in the background. Probably not all the settings are needed, but this list will give you a good starting point.

Please contact RaceChrono support if something is incorrect, or you have something to add.

Disable Wifi Power Saving Mode — Galaxy S7

By default the Galaxy S7 has a WiFi power saving mode which affects bandwidth and response when the device screen is off and on battery power.

New method to disable WiFi Power Saving mode. Should work for other Samsung devices.

The *#0011# method I’ve found creates a file /data/.psm.info and contains a 0 to disable power saving.

Open a Terminal session.
su
echo ‘0’ > /data/.psm.info
chmod 664 /data/.psm.info

Or you can use my app to toggle the setting.
Play Store App

Power Saver On

Power Saver Off — Sees a fast response every other ping.

Follow the instructions below or use my own attached modded file to disable this power saving mode. The option is in a service menu but the activity hides the power saving button to toggle it.
My scheduled Wi-Fi tasks now don’t struggle.

My S7 is a UK G930F. Will also work with G935F.

Copied /system/priv-app/serviceModeApp_FB/serviceModeApp_FB.apk
Decompiled using AndroidMultiTool and latest apktool.jar
Edit /res/layout/wifi_information.xml
Change the powersavemod lines — android:visibility from «gone» to «visible»
Recompile the apk
Copy back to device /system/priv-app/serviceModeApp_FB/serviceModeApp_FB.apk
Restart device.
Open the Dialer and type *#0011#
Click More
Click Wifi
You will now see the WIFI Power Save Mode option

With Power Saver of, screen off and no USB connected, you get better bandwidth and a quick response every other ping.

Permanently disabling android power saving

I have UCedge running in our facility on Samsung galaxy j3(6) phones. UCedge is a VOIP app that allows you to talk with our main phone server. The issue is that since the last update on the phones version 7.1.1 of android OS if the phone is locked for 10 minutes it shuts down either the wifi or the app, or puts them to sleep and calls do not come in if the app is asleep. I can turn power saving off and it still does this. I have also turned power saving on, then added the app to the unmonitored apps and it still does this. Keep wifi on during sleep has always been turned on. Does anyone know a way of disabling power saving other than this, I have tried uninstalling the app and reinstalling, factory wiping the phones, and just about everything I can think of to get them working with no luck.

Thanks in advance.

The problem has to do with how android handles open apps and memory management (wake-locks) it’s not necessarily a power-saving issue, but one of persistence and app permissions that is baked into the OS at a core level that is likely not user customizable without rooting or a new ROM.

Everything you could want for Rooting, and new roms, can be found at XDA https://forum.xda-developers.com/galaxy-j3-2016

Unfortunately, the roms are likely to be the same version or newer, which means you may still run into the problems with the apps being disabled while the phone is in standby. XDA thankfully has some marshmallow (6.x) variants
