Battery woes....help?

[Anthow68]

I've had my V20 on At&T since launch day. Up until a few weeks ago, the battery life was great. Lately, it's been draining a lot (especially at night). After several calls to AT&T trying to figure out the problem, I was sent a warranty replacement phone and a new sim card. My problem still persisted, so I got a new battery a couple of days ago. Problem still exists.

My phone is draining between 40 and 50% while I'm asleep. No wifi, no Bluetooth, and location is set to high accuracy. I can't for the life of me figure out what is going on. I have noticed that my signal at home has started fluctuating between 4G and LTE a lot, but I don't think that would cause this much of a problem. Below are screenshots of my battery stats from both the Batter usage screen and from the app Power Doctor. I don't usually use third party apps for battery monitoring, but I wanted a second opinion.







These screenshots were taken right after I woke up this morning with the battery fully charged before I went to sleep. You can see that my battery drained 42% just sitting on my night stand.

I will add that I have tried a hard reset and also safe mode. Nothing seems to solve the problem.

If you are running "power doctor, battery doctor"... or power management apps its best not to. They could be fighting with the OS, turning off certain aspects while the OS struggles to keep them on. Its best to let Android manage power. I would delete it for a few days and see if anything improves.

Are all your apps fully updated? Maybe there was an update overnight?

Maybe the ATT coverage is not as reliable as you think and your cell radio is chugging battery overnight?

Does it get better if you put it on airplane mode?... Im not saying this is a solution, but more as a way to narrow down whats going on.
If you have a wifi network, merge onto that and turn off cellular data... see if that helps.

What does your Ignore battery optimization setting look like? FWIW I have all of those things unchecked, except for Android wear to make sure watch is receiving full notifications and updates.

I've only had the Power Doctor app installed since yesterday. This issue has been going on for weeks. I usually stay away from those types of apps like the plague.

I am OCD about keeping my apps up to date.

I want to think it's my coverage as up until a few weeks ago, I would get 4 to 5 bars of LTE consistently. I have tried to talk to AT&T about this and the only solution I get is put the phone on wifi. I told them I'm not paying them for wifi, I'm paying them for cellular service. If I put the phone on airplane mode, I only lose between 5 and 10% overnight. Turning off mobile data does nothing.

I do not have anything checked under ignore battery optimization.

Definitely seems like something is going on with your cellular network. Since turning on wifi as well as airplane mode clearly helps, and switching the battery and device to new ones does not.

You mention the problem just recently started occurring a few weeks ago. Maybe un-install recently installed apps, one at a time and see if you can isolate things further.

Hopefully others can have a better suggestion though.

Good luck!!

Do you have Facebook?

I do have the Facebook app but don't use Messenger.
