Nexus 4 Battery Drain

Arron17

Starting from a few days ago my phones battery life has suddenly become terrible. It won't last more than 8 hours even on aeroplane mode and with battery saver on. The graph for the battery is like a ramp. "imgur.com/xgn62cD". Better battery stats reports it's 100% deep sleep with no wake locks.



Any one got any ideas?


One other thing I did notice is that when you wake the phone the battery stats look normal so after about 2 hours the battery will have gone from 100 - 95 and the graph shows that. But after about 30 seconds of turning the screen on the battery jumps down from 95 to around 70, on this occasion, and redraws the graph with the bad battery drain again.

Sorry I didn't want to duplicate. I wanted to discuss how I could fix it myself here. And discuss the warranty issue in the other thread.

I have done a factory reset and checked the battery drain and it doesn't seem to be an app that is causing it.

It's fully updated to 5.0.1. I've tried different apps to check drain from apps and they all say that it's just the phone in sleep mode or the android system.

I don't know if this is relevent to the issue. But the battery stats take a while to update. You will wake the phone and it will display what looks like a normal battery percentage for the time it's been asleep. And then within 30 seconds it's dropped back down. For example my phone was on 100% last night, When I woke up 8 hours later the phone reported 45%. Within 30 seconds it dropped down to 5% and then 10 seconds later turned off and wouldn't turn back on without charging.

[EDIT]
The main reason I think it's a hardware fault is the way it started doing this.

I had it in my pocket in the car and it got so hot it was burning my leg and I had to stop and take it out of my pocket. When I took it out it was running around 50C so I turned off all the wifi and data and it was reporting 50% battery would be gone in 50 minutes.
By the time I'd got home, whatever was causing it to heat up had drained the battery all the way down. So far down I had to charge it for 10 minutes before it would let me turn it back on. Since then the battery has been terrible whereas before that it was fine getting me around 1 day standby time.

Yes even though the reasoning behind calibration on Android is false it would at least clear the stats if nothing else ..
The battery stats are essentially not involved in calibration of the battery .

I tried to follow that guide. I did the first method as I don't have root access on my phone and the app doesn't seem to display the mAh correctly. The battery in the nexus 4 is 2100mAh but the app never displays over 200 like in the screenshot on that site.

Lots of reported problems on Lollipop & Nexus.

Try the following. It is actually easier than it first appears

Older Nexus devices such as the Nexus 7 2012 and Nexus 4 seem to be widely affected with poor performance issues after updating with Android 5.0 Lollipop update.

Some of the widespread issues noted with the affected Nexus devices include sluggishness, abnormal slowdown and random app crashes.

Here is how to use a potential performance fix on the Nexus 7 2012, manually:

Press and hold Power and Volume Down buttons simultaneously until the device logo or Android logo appears on the screen.
You should now see a large arrow at the top of the screen.
Tap Volume Down repeatedly until you see Recovery in the arrow. Then tap the Power button
Then you will see an android on his back, chest open with a red triangle and exclamation mark.
Now hold Power button and tap Volume Up once before releasing the Power.
A list of items should now appear at top of screen.
Tap Volume Down until the item to erase or wipe the cache partition gets highlighted. Then tap Power button to initiate the wipe process.
Status messages will appear at the bottom of the screen. Be patient as it can take about 10-15 minutes to complete. When done restart the Nexus device.
