[Q] Sleep of Death with Stock

So I read about other people having this problem with custom ROMs or rooted phones but I am on unrooted stock after OTA. I thought was one of the 60 or whatever apps I bought during the 10 cent promotion but I uninstalled them all and I still had the problem. It's not frequent but it's happened 3 times in the last couple of weeks. It's mildly annoying to have to pull the battery but the part that I can't live with is that whenever it this happens, my battery drains like crazy. The battery usage drops off a cliff and I caught this one after no more than 5 minutes. Any thoughts on this? I don't have an SD card so it's not that. Thanks!

to find the rogue app use betterbatterystats and cpu spy. not sure if they superuser. also badass battery works too.

Mine did this the other night on Calk's ROM. Something got stuck keeping the phone awake causing that cliff like drop off.

Happened to me on stock once, installed some game but didn't play it so I don't think that was the reason. It was either the default browser or the contact list.

Thanks for the replies. I figured it was an app but wanted to be sure before I started deleting things. I was just worried that this might be something to do with hardware or something.

I have same problem with different roms and i don't know what to do...

I had the same problem I figured out it was my wifi being turned on all the time. I have always heard leaving your wifi on when it's availible was supposed to save battery but I checked in better battery stats and saw there was almost 7000 wakelocks in a 5 hour period. I turned wifi off problem solved I only turn it on when I need to.

It is happend even wifi is off.

Your battery might be going bad... take it out and spin it on a flat surface if it spins freely the battery is most likely done.

My battery have 3 months old. My s2 is new....

Same thing is happening to my friend's white E4GT, I think there might be a defective/bad batch.

Is anyone else's battery on crack?

Usually I can go a full 16 hour work day without needing an extra charge, then last week it started not holding the charge so well. In fact Tuesday it had 30% and I left the house for half an hour, and when I came back the phone had shut off and was at 0. I hadn't even touched it. I am on a mix of Wi-Fi and LTE. Anyway, that was odd. Now look at the battery usage...

Do you have a screenshot of the stats when the battery went all out of whack?

My android system has been going crazy the last week or so, usually would be at 5% our do but lately has been 40+ easy... been to lazy to wipe and re flash as I'm sure that will fix the issue, but lately I've been near power all the time so it hasn't really bothered me.

I flashed with Highonandroid and got 30+ hours. Probably could have gotten double if I didn't kill half of it installing all my apps back on.
What rom are you using?
On the stock image I was only getting 9 hours.

it looks like weatherbug and google maps take a lot of battery

i never truly understood why people boast of their battery life when they have the screen on for 10 minutes in 2 days

if you are not using a phone, turn it off and the battery will hold charge for many, many days.

Battery help.

I've noticed a sharp decline in battery. With only 35 minutes of screen on I've already lost 11%. In this case, index service seems to be using a lot of battery, but this is the first time I noticed that. I was getting like 7 hours of screen on, now I'm getting about 5.

IndexService works hard when you add new docs/books, it scans all of them, then it should go away. For some reason it didn't find 1 or more files on my SD card, kept scanning for hours. Did you add anything new to tablet?

I downloaded a powerpoint and then converted it to a pdf. It seems like it just won't stop. Everyone I look at its running time it is increasing.

You could delete recently added/changed files and see what happens.

I restarted and now it seems like index service is still running frequently, but no longer nonstop. Regardless of index service my battery still seems to be worse by 2 hours. It was awesome for the first couple weeks and now its just average. I don't even have that many apps.

if you're rooted just freeze the indexer.

I'm holding off for rooting until Knox is circumvented. Plus I don't see recoveries or custom Roms yet so I don't have all that much incentive.

I am seeing similar numbers on my new Note 7 on AT&T. So far the battery life blows for me, the set up is identical to my Nexus 6P except I have Google Now always on (launch from your voice regardless of whether the screen is on or off) turned off. All other apps are the same, sync is the same, etc. I'm hoping it's something simple or the phone just needs to settle in otherwise I'll go back to my 6P.

Tmobile here
Im guessing it still has the wifi calling bug from previous samsung phones

Good..so it's not just me. Android System is usually around 20% and now Android OS is around 20%. I am also on AT&T. Battery life has been pretty subpar in my opinion, so I'm hoping it settles in after awhile.

Yea, same here. I just tried wiping the cache partition, so we'll see if that makes a difference.

Try to switch to airplane mode first, second reboot

It looks like you have WiFi. Reset the SIM card.

Well, if you don't have carrier signal in your area (there could be some issues with your carrier, for example), that's pretty much what's supposed to happen. You have no mobile data, cause you have no carrier signal. But yeah, you could also try Airplane mode ON/OFF, Reboot the phone and Reset Network Settings. Hopefully one of them will fix the issue.

Good on you for coming back and telling us. Glad you got it sorted.

Lmao...no worries...I think most of us have done muuch worse when we were drunk and couldn't remember ANYTHING past a certain point! Actually more than a few times...back in my college days mostly. Hate it when your friends start with the 'You won't believe what you did last night!' stories. smh...
