Android 5 battery drain

[stuarta99]

Hi,

I'm after some thoughts if I may a out battery drain since lollipop upgrade. I know my phone is almost 2 years old but so is my wife's N4 and her battery is amazing since the upgrade. Now I can only guess that maybe I have an app that she doesn't but I regularly get to 12% within a days charge at the moment and wondering if a factory reset or cache wipe might help.

If I do either of these, I guess I need to backup my contacts and any files that I might have on my phone?

For interest this is my phone today, off charge about 10am so been about 12 hours. I never seem to see a massive draining app.

Something seems to be waking the phone relatively often, and there are times when your cell signal doesn't look that great. A few more battery stats would be helpful. Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).

A cache partition wipe won't erase any personal data, so it doesn't hurt to try: https://support.t-mobile.com/docs/DOC-5994

Ok ta. Battery been a bit better today, but hardly used it for anything. Currently sat at 56% and screenies attached. Will monitor it tomorrow when it might get more use.

Just checked the wife's to compare and she's on 86% with the screen on as 11mins compared to my 45mins. Not sure what kind of ratio it uses

Thinking maybe the screen percentage is correct. My wife's was 86% with about 11mins so about 1.2%/min. Mine was 56% after 46mins so again about 0.9%/min. Now at 45% after 1hr 13mins so 0.75%/min. So going by that it's not bad I guess. One main app difference is that I use Facebook and she doesn't. Did read a post just now that it's a battery hog

Thought it was better today with 43% after 1hr 20mins screen until wife showed me hers at 71% with 1hr 9mins

Something seems to be waking the phone up pretty frequently. Unfortunately, there's no way to analyze wakelocks in KitKat or Lollipop unless your rooted (actually, I'm not even sure about Lollipop). Make sure Location Reporting is off in your Settings>Location menu, and also look through your apps and widgets for things that might be accessing the web frequently to refresh data. For example, if you have Facebook, go into its settings and change the data refresh rate to the longest interval, or to Never (you can always refresh manually).

I've just reset my phone and refraining from putting apps like Facebook as that it one app my wife doesn't use. I'll see how it goes over the weekend and compare

Make sure you don't have GPS running constantly. Also make sure you have your screen timeout and brightness set to something reasonable.
