S7 edge help with battery after update

[Android Central Question]

After update last week, battery discharges at about 1% per minute now! Help!

Sounds like there's some rogue app using the battery excessively. Are you able to view which apps are using your battery and see if one is excessive? Otherwise go in to safe mode and see if it persist.

Doesn't appear to be. Take a look at these screenshots.

 

[Chris5483]

Very interesting. The Next Step I would recommend is putting the phone in Safe Mode and then taking another screenshot after an hour or so and see if that slows down the battery depletion.

 

[Csawyer7845]

I am going to fully charge it and then put it in safe mode and see what happens . If it is still draining, think the battery itself went bad?

 

[Chris5483]

It might be.... It's not that old of a phone. If you could see how safe mode works, after the results I can mention other contributes who might have more ideas.

So these are with my phone in safe mode and sitting idle with screen off.

Bad battery or new android update?

It's a little better... But not much. I messaged a frequent user and hopefully he/she can help.

Thank you for your help! Here is Gsam report

It looks like you might be getting into too technical of stuff for even me. Was it an update to nougat or just the Verizon security update? They're not usually very helpful in chat, but if you don't get any answers here you might chat with them and see if they have any type of solution.

 

[Csawyer7845]

Not sure. It did an update on 28th. I have auto update on. Battery started dying quickly about 3 days ago. Literally have to plug in throughout the day with minimal usage

 

[Chris5483]

I'd see if the other user weighs in, otherwise chat with Verizon. I'm not sure how to help anymore.

Poor cell signal is a common culprit, and I see that in some of those screenshots, the cell signal strength indicator is only at about 1-2 bars. I see that you have GSam installed -- can you show us the Cell Signal Strength graph over the course of an entire charge?

 

[Csawyer7845]

Here you go

It does seem to fluctuate a fair amount, with a good amount of time in the medium range. It'd be interesting to see how your battery is if you're in an area of consistently good signal.

 

[Csawyer7845]

Never had an issue before and travel same streets etc. Anything I can try to strengthen the signal?

 

[B. Diddy]

There's not much you can do about that apart from getting a signal booster from your carrier (which is for home only).

Have you already tried wiping the cache partition? https://support.t-mobile.com/docs/DOC-28028
