why is my battery so bad all of a sudden?

Last night I went to bed at like 60% battery. I woke up today and my phone is completely dead. I slept for 5-6 hours and its hard to believe that my phone dead. I have NO idea how is this possible?
Here is a SS of my battery. I'm running AOKP(Jellybean 4.1.2)Task & Ktoonsez

You probably got a lot of calls/texts cuz ur screen probably turned on because of the fact its a whopping 49 percent

But the stats are only accounting for 51 minutes of up time, 49% screen usage at that uptime is not difficult to do.
What Rom are you running? Kernel? Did you recently download/install any new apps or games?
Generally this issue is caused by two things, 1) android system going beserk 2) a rogue app keep the phone from going into deep sleep.
Best thing to do is to fully charge it and then let it sit idle for a hour or two and then see what your stats report. Better battery stats is great for pin pointing causes for battery drain.
In the past, I have had a few games cause excessive battery drain as well as android system. The first was easy to remedy, install and reinstall worked 90% of the time while the other 10% required me to completely abandon said app.
Android system is a little trickier, always had to re flash the Rom to fix that, but thanks to data backup nandroid, that only takes a few minutes to backup data, flash Rom and then restore data... leaving me with my phone in the exact state that it was in before, , sans the battery drain.
Good luck bud

Well last night I did a serious wipe on my phone. I reinstalled my rom and then went to sleep. better battery stats for free? or is it the app that cost $2.89. I don't mind paying $3 bucks for an app to help me figure out whats wrong with my phone.

Make sure it is going to deep sleep. Change governors sometimes ktnoozconservacts weird so just click o load to defaults reboot and that shohld fix theproblem

Download BBS. It's free here on xda for members.... Just do a search. Downloaded any apps lately??

note 2 update to 4.1.2

hey i was a while ago waiting for the 4.1.2 update of the note 2 n7100 ... i saw a couple of days ago that people are not satisfied with the update and that it is causing problems ,, mainly the " SDS" and others complaining about freezes.
can someone tell me what is the update version that is having this problem??
also have anyone here faced this problem with the update

if your eMMc chip is vulnerable to sds, the 4.1.2 temporaly fix it,also it fix exynos abuse
The problem i have faced since the update is:
The phone will never go on deepsleep,reducing battery life.
Is highly recommended that if your phone is vulnerable to sds upg to 4.1.2

well i checked and my phone is not vulnerable ,, i saw that the update has some new features that seemed to be useful , i will consider updating ...
anyway thanks bro

There are no problems with 4.1.2, it has several small improvements. Never had reboot or freeze or anything wrong happen. The only problem is battery life which is shorter then with 4.1.1....

I don't have any "numbers" but it is so OBVIOUS, not small difference.... I.e. overnight drain was 1-2% now it is 10% at least... previously I charged my Note II until midnight, in the morning it was like 98%, I used it whole day at work and came home at 5pm with like 40-50% battery. Now I charge it at work until lunchtime (12:00) and come home and it is like 40-50% level... so NOTICABLE diference....

Yes, I agree, I wouldn't flash if I was not afraid of Sudden Death Syndrome, since I have the chip they say can fail under 4.1.1....

Taken on my 4.1.2 stock device. And that's with BT on all the time, and WIFI on when the screen is on, and just a brief 10 minutes or so on charge.
Battery life on 4.1.2 is just fine.

some devices will have normal battery life on 4.1.2, my phone got a random wakelock with 4.1.2, while my mother note 2 with 4.1.2 got normal battery life.

I state quite clearly that I did charge it, briefly. It makes bugger all different to the overall power consumption, which you can see quite clearly.

forget everything now,,, look guys i am updating my phone .. tonight i will post my battery status
however; tonight i will include battery status of my phone with no background apps..[i will shut down everything including wifi , BT , antivirus]
tomorow i will turn on BT, WIFI & lookout antivirus

I was expecting to find more people talking about issues with the 4.1.2 upgrade - does appear to be a minority (that I am unfortunately in)
Since upgrading, my (sim free) Note 2 has gone from being just about perfect in operation and behaviour to suffering;
- Daily episodes of freezing (often requiring a battery out to reset)
- 2 or 3 times a day it will randomly re-boot itself
- whilst typing on keyboard often suddenly goes very laggy
- battery life has *defnintely* worsened (probabbly by around 15% or so per days use - it does deep sleep though)
- calendar view/settings reset themselves every re-boot (annoying)
All the above annoy the cr4p out of me, as I am super picky with my phones/devices and I'm pretty dissappointed with this - given the phone was SO slick pre-update. I can't stand to have a buggy phone, so unless there's an update to cater for these issues very soon (.3?) it's S4 for me.
(I would roll back to .1 in a heartbeat, but looking at how to do it, it's tantamount to a rooting processs in it's 'complexity' - you guys may be adept at such things, but to me they just look like an uneccessary ball-ache - shame there can't be a kind of 'macro/apk/idiots program' that does it all for you! But there you go, I'll have to suffer for now and see which way to jump in a few weeks I guess).
My advice? DON'T upgrade to .2 - I can't see any discernable benefit in day to day use, but I can see a LOT of irritating downside.
Very pi55ed off

Sounds like you've got something else going on than the 4.1.2 update. I have NONE of those issues at all, and battery life is just as excellent as it ever was.

i'm on 4.1.2
I've updated my mobile to 4.1.2
Baseband version : N7100XXDLK7
Build number : N7100XXDMB5
and i don't have any single problem with that update....
and the battery performance has really improved

overnight test ... without BT or WIFI but antivirus is on

tonight i will put BT and WIFI on

Battery percentage jumps down 4.2.2

I think this is quite serious, but I don't know if this is only happening to me or it's happening to others as well
I had this weird battery issue.
I was playing a game and stopped when it warned me that there's only 14 percent left. And then I went to check my emails for about a minute, then the battery suddenly turned 0 and the phone shut down.
I wouldn't want this to happen to me when I'm not at home and then a 14 percent battery suddenly dies on me
I'm on 4.2.2 rooted with v13 of easy rooting tool kit, locked bootloader.

Same batttery
I have been using the new Build:10.3.A.0.423 for a few days now and even I am also on a Lock Bootloader BL and my phone rooted with Doom's v13 kit
But so far I found the battery life to e similar I haven't anything strange in terms of battery life

I have the same problem and it started right after updating to 4.2.2 without rooting. I noticed that after a reboot, my battery % jumped about 20%. And then I lost that 20% all of a sudden and the phone shut down.
I installed a clean copy of AuROM and wiped everything, but it is still doing it. I just saw the battery charge jump from 60% to 80% after a reboot while the phone was plugged into the computer.
Does CWM still clear battery stats? I'm going to do a fresh clean install of the .423 ftf and see if it goes away.

It's doing it again. I rebooted and my battery percentage jumped about 30%
I'm on a clean install of 423

It's not happening to me anymore.
What I did was to use battery calibration, an app from the playstore for rooted devices. Someone pointed out to me that after a rom install, the battery stats kinda gets messed up. I think it should be the job of Sony to do that, but since we're rooted, maybe there's something that made this happen to our phones...

Could be. I'm surprised no one else has mentioned it. I had found the calibration app before reading your message and I ran it and it was fixed. I am having issues with my push notifications so I did a wipe/factory reset through CWM and now my battery is all messed up again. It jumped 40% and then it went back down. Now it's back up. I haven't deleted the battery stats file again so it probably has to do with that.
Must be a bug with 10.3.A.0.423

nah im back to 4.1.2 much better , i dont care about transparent bar if i got many bugs such as battery drain GPS, etc..

I actually have this exact issue on stock, unrooted. It seems like every time I reboot the phone, the battery percentage will jump up by anywhere from 10-30% (though not always). I usually charge it up when this happens so that it doesn't just drop to 0 on me. I only wish there was a way to calibrate the battery on a stock, unrooted device. I have yet to have it drop to zero and shut down, though.
Does anyone happen to know if there's a solution for an unrooted device?

TIME TO ROOT GUYS

Rooted my phone yesterday and my phone has not been in deep sleep all morning. I unplugged it this moring around 9 am and 5 hrs later my phone has been awake for 5 hrs. So as of right now, yes I can confirm that my phone has not been in deep sleep since I rooted.

you are the 2nd person to confirm this to me..... I wonder if is only happening to tmobile edges since we have to use the wrong root file ??? or is happening to the other edges that have a correct root file ????
seems like I'll wait to root specially now with the built in battery

I decided to start fresh and will wait for a fix on this root issue. Hopefully it comes soon.

I can confirm this as well. My battery life is atrocious with everything disabled (google now, location, wifi, etc)...less than my Nexus 5 with everything enabled.

Same here

http://forum.xda-developers.com/showthread.php?t=3079176
Here's a great guide if you guys decide to unroot and start over. Make sure you guys thank the OP of that thread.

I'm not sure how to actually confirm it for you, but my phone has been off charge for 2 hours, and I am at 98%.
I bought the phone on Friday, ran the OTA that popped up as soon as I powered on whilst still at the store, came home and rooted. Disabled a bunch more bloat, but the battery wasn't great. It was iPhone territory.
Yesterday, I started over with a full KiES install that included that OTA. I rooted again and then re-installed everything from TB. This has seemed to make a marked improvement. That said, tomorrow will be a true to test of the battery as It's a work day, I'm travelling, and I'll be roaming up in Canada.

This is very helpful - thanks! Please, if you think of it, let us know how Monday goes? Appreciate it!

I looked a little bit more through this thread and saw that CPU Spy app, so I ran it, and I am deep sleeping after root. Please do note, however, that I have WiFi set to always on, one of my email accounts in Nine is set to not sync at all during off-peak hours (which includes the weekend), and the other one only syncs every two hours during the same period.
I will definitely still update on Monday as it will be punishing.

So you are rooted and going into deep sleep ??? Just want to be 100% sure before rooting my device

FWIW, that is how I understand it. I think I'm going to take the plunge, using the CF-Auto-Root-zerofltetmo-zerofltetmo-smg920t file. Would love if someone out there could tell me that I am on the right track!!

Correct. Clean flash is a must, however.

This is where I am confused. Define (please) "Clean Flash". I did a restore using SS a few hours ago, but have since restored data, apps, etc. Please elaborate. Thanks.

Deff didn't work for me...... I had perfect deep sleep over 4 hrs of screen time...... I had done the samsung smart switch now rooted and yeap no deep sleep at all stuck at 400mh all the time

Question Battery faulty?

Hey guys.
Just switched from S21U to this sweet baby and so far I am missing nothing from Samsung. Besides the good battery life.. I got with the galaxy S3 better SOT In idle I loose so much, it's incredible. I thought its A11.. no updated to A12.. no installed A13 Beta 2 and still crap battery life.
I disabled everything that Google or YouTube suggested me already but nothing helps. I restored my backup from the cloud (the switch from Sammy to o+1) can that cause poor battery life?
I am thankful for any help or tips.

Maybe one/some of the radios (wifi/BT/NFC/GPS) are on?
I'd suggest starting with charging the phone to 100%, then putting it in airplane mode for 12 hours (say for the night), then see it: if the battery looses more than a few percent, then there is indeed something wrong with it. If not, then it's just a matter of time that you'll figure what drains the battery.

Dude that is one of the best ideas I've ever read when it comes to checking out a battery thank you for this...
I'm having issues with my 9 pro draining again myself...
last time I had this problem I did a factory reset and it really helped a lot with battery drain...

I myself did a factory reset last time I had a battery drain issue w/ my 9 Pro and it helped a lot..
First definitely try what @viktak recommended and then go from there..
I personally do not have a lot of stuff running in the background like sync, back up, find my device, and definitely don't have stuff like Instagram or Facebook running on my phone.
a poorly designed app can hog up your battery...
also what did I do to help a lot is my phone is rooted of course so I have SD maid pro and with that I can check and see what all is running on my phone..
Under developer option under running services it will tell you the basic services that are running but it's not going to tell you everything that's running on your phone...
Hopefully you get it figured out and yeah Oneplus is so much better than Samsung.. I know it's an opinion but I just can't stand using a Samsung devices after using a OnePlus...
I bought the Samsung Galaxy S8 Ultra tablet a month ago and don't get me wrong I freaking love that thing it is badass but I would love it a lot better if Oneplus would make a tablet like that. lmao

It really bugs me that you pay a hugh chunk of money for a samsung phone and it being paid off, Samsung says no-no you can't unlock your bootloader to customize YOUR phone....
try going into settings/battery and look for what is eating it up. that might help to!

yeah I agree..
I tell you what saved me is having ADB and Fastboot for Android ndk Magisk module...
it's nice man being able to hook my 9 pro up to this Samsung tablet and remove the bloatware just by using termux...
first thing I got rid of was Samsung's digital well-being.. man what an intrusive app!!
sorry OP for off topic....

Hey guys!
Thanks a lot for your advices. I will try putting in airplane mode tonight and check tomorrow. I will try resetting my phone if it drains while in AP mode.
I can send it back to Amazon within 2 remaining weeks.. when I root and unroot, will something like Knox be triggered?
Thanks so much <3

OnePlus doesn't have anything like Knox. If you factory reset and re-lock bootloader it's back to factory state. (Knox was awful, I don't miss Samsung.)

Hey guys!
Thanks a lot for your advices. I will try putting in airplane mode tonight and check tomorrow. I will try resetting my phone if it drains while in AP mode.

Even if the phone is rooted, OnePlus accepts returns.
If you are not successful in your attempts to find the culprit, you can use BetterBatteryStats from HERE, read the first couple of posts in that thread and generate an idle dump file as described there. It can be posted in that thread for help mentioning the airplane mode result also.
The airplane mode result is the bottomline, below which you can't go and if that is high, return the phone.

So a quick update:
i have not lost any percent battery during flight mode (10 hours)
Had then over the day almost 5 hours SOT and still had more than enough battery. (yeeey)
I live in Germany and work in Switzerland and right next door is France and my guess is that when automatically selecting network, as it is set by default, it switches all the time between the countries.
However, when I tested this with flight mode, I was on the home network and I assume there were no switches, which is why my battery got through the day better
I'm back at work right now and have manually selected the Swiss network this time and I'm very curious to see what percentage I'll have at the end of the day.
Does roaming drain a lot of battery that much? Can I check without root what consumes the most energy? BBS needs root, right?

No. If root is not available, you can grant the required permissions via adb. After installation, when the app is opened, the permissions screen pops up and guides you. Ofcourse, if root is available, it is only a matter of allowing root permission.
