She has not changed anything, but this has been draining her battery bad.
Any help on what to do??
I would first follow the below, and then update all apps/OS/Firmware. The fact that the Google Play Services is using this much of your battery is alarming- have there been any recent installs of Applications that could be forcing the phone to try and connect/sync regularly?
I think the best way to save battery (I found) is:
- Disable/Remove ALL un-used apps;
- Change sync settings to when open (I find using Snapdragon BatteryGuru is very effective)
- Use AutoMateIt/Tasker to make events trigger power saving actions.
- Minimise Widgets being used, as these require data to refresh
- If in poor reception, put phone into Airplane Mode (also when you're sleeping you do not really want calls anyway)
I achieve all of this with the following:
1- 2 Rules on AutoMateIt; when battery is less than 30% disable: sync, WiFi, 3/4G, set screen to 25% brightness, with 1 minute timeout and; If WiFi is idle/not connected, disable with a delay of 5 minutes.
2- Snapdragon on, with all programs set to sync when opened, not in background. Although some exceptions are made; Weather, Traffic and E-Mail.
3- I disable the stock SMS and use Hangouts (or vice versa), disable Mail and use G-Mail, disable all inbuilt notes, task and internet as we often use our own defaults etc.
All in all after doing this, I now can use my phone almost continually from 05:00am to 09:00pm and have 30-40% left.
These simple things help extend battery life considerable- although having apps like this run in the background can be just as draining. Been on my phone for 14 hours, almost continually and I'm at 37%.
