Battery skips battery percentages - Nexus 7 Q&A, Help & Troubleshooting

I've had my nexus pretty much since launch and have been rooted since day one. The problem I've been coming across is that my battery drops from 85%-83% and 70-68% and a few more (probably about 3 more "couples") as the duration of the battery goes on.
I ran a variety of roms on 4.1.X such as AOKP, paranoid android, and kaos droid. I also used a few different kernels such as faux and motely.
The battery problem has been happening for a while. I just flashed the latest version of AOKP with the stock kernel(4.2.1 mr1 build 2) and thought the battery problem might go away. It didn't.
And when the battery drops, I wouldn't say the battery percent stalls on the percentage before it drops. Meaning it's just a normal drop, if that makes since. lol.
This problem has proven to be annoying and I lose probably about 10% each battery cycle. Is there anything I can do?

What is up with the battery life on 2.3.3?

After replacing the battery with a 1600 mah Seidio battery. I still get bad results. For example, during lunch today my phone was at 50% in my locker. After 4 hours, I was at 21%. My Sync, GPS, BT and Wifi are all OFF.
How is this possible?
I use to own a Nexus One and in 4 hours it would go down 2% with CM6. Is Gingerbread an issue here or does my phone need RMA repair?
2.3.3 gives me better battery than 2.1 or 2.2

superaosp from [email protected] stock kernel or redstars depends but cm7 and stock OTA gave me better battery than 2.2/2.1
I'm running stock 2.3.3 and battery life is by far the best over various android versions.
2.3.3 has some weird bug where every once in a while the system gets into a weird drain state like it doesnt go into deep sleep correctly. i just got hit with this last night. it does happen all the time, most of the time on 2.3.3 battery life is excellent. i will lose 6% over 8 hours. but when that awake bug DOES kick in, battery drops like yours did.
you just have to reboot and check it again, the bug likely will clear itself and you wont see it again, for a while.

yes, this is exactly what the bug is. sometimes randomly on GB the phone stays awake for no reason, for hours. but when this DOESNT happen, batteyr life is superb. i only get hit with this bug once a week or less.

My N1 on 2.3.3 goes completely dead after 12hrs. I found the solution when doing a Google search. It's to go to Wifi Settings, Advanced, Wi-Fi sleep policy, and change it to Never. You'd think that would reduce battery life, but for some reason now my phone's battery life is very significantly improved. Now it's only down to about 30% after 19hrs when I put it on the charger.
It appears that 2.3.4 will address battery issues in Gingerbread.

I dont think its Gingerbread, ive used both stock and CM7 on my N1 and i was having good bat life on N1 stock gingerbread about 5-6 hours with heavy use, and with CM7 official rom i get 7-8 hours heavy use and up to 19 hours on days i barely use the phone, and on standby i can confirm 8 hours (while im asleep) it drains 6% by the time i wake up of course i do have it personalized and settings applied for bat savings.
I haven't encountered this bug with CM 7.0.3 (based on 2.3.3) but I found it very useful to let the phone just drain the battery completely once in a while (once in a few weeks) and than fully charge it.
After doing that, I can go through two days with regular usage of the device
I'm on CM 7.0.3, 2.3.3 and I'm only getting 13-15 hrs if I'm lucky. Wifi and bluetooth are off only syncing gmail and google contacts. I barely even touch my phone at work for 8 hrs and the battery life sucks.
Another weird thing is that once it gets to 15% left it just automatically dies and shuts down...very frustrating, I'm on the latest pershoot kernel too, the phone was given to me for free last month and it was originally purchased in Feb '10 so I just figure the battery is old and worn out.

No. Your battery is not aged, it just needs re-calibration.
One simple way is to re-calibrate your battery is to charge it when the phone is off or charge using a desktop charher, and you have to over-charge a bit - just leave the battery connecting to power source for an additional 1 hour or more, when the charging process has been completed.
This works every time for me.
Keep in mind that from time to time the battery may need to be re-calibrated again for peak performance.

battery?

im running the stable cm7 release and my battery life is terrible. i followed the guide on the forums here on fixing your battery life, charging to 100% pull battery put back in instal battery fix etc and overnight (short 5 hour night btw) i lost over 25% of my battery life, doing nothing ! wifi off data was on but i only recieved one or two emails all night. is this normal for cm7?
i read about how people are getting 20+ hours battery life while using their phone, if i leave my charger at home and go to work my phone is DEAD halfway through and all i use it for is the occasional phone call mabye 5-10 texts throughout the day and an email or two... how can i fix this?
I read somewhere that if you flash another ROM with battery not fully charged, it messes up calibration and you have to calibrate again. I am still with stock Blur just because I read so many issues with so many people about batteries
I hope you can get it figured out.
anybody?
is anybody else having battery life issues with cm7? if not did you do something to fix it? i have no idea what to do, the phone pretty much has to be tethered to a charger or it gets drained ridiculously fast. If i hang out with a few friends and use my phone during it i literally have to stop using it after around an hour or so because the battery's about to die.
Is there a certain rom with exceptional battery life that i can try to see if mabye its a hardware related issue? i seem to remember having horrible battery life for the day? or so that i was running stock ATT gingerbread.
I use Aura 1.2.2.2 (debloat) and get average battery life. Comparable to what I got before I installed third party ROM. If you want to try that one and see if its just CM then give it a go.
I had a battery problem after flashing to CM with a previous phone (OG Droid) but it was because I flashed while I had the phone plugged into the charger. It took a while to get it back to normal.
I doubt its CM. I dont know if its something draining your battery in the background or if its a result of weird calibration due to the flash.
my battery life has never been hte greatest but recently i got it working really well
I use the latest weekly build of CM7 and here is what i did
upon fresh install:
wipe battery stats
THEN:
kill battery
charge as far as it will go
clear battery stats (use battery calibration app)
take out battery
wait to reboot(missing battery)
put it back in
let it charge for 2hrs
reboot and unplug
kill the battery
charge to 100% while off (no interuptions)
Enjoy!
i have found that the more cycles my battery goes through 100-0-100
the better it gets
these steps almost tripled my battery life (along with Weekly 3)
there is a bug some people report with CM7 about the suspend process. (i have it, you can search "suspend" in the CM7 thread and see others are as well) load up the app betterbatterystats (there is a thread on xda that has the apk) and see if you have that bug.
I'm on nightly 20 having good battery life

i installed betterybatterystats as you guys recommended and im not entirely sure how to read it but the suspend process shows at the top of the list so i assume thats the process which is eating up my battery? Is there a fix for this? i do like cm7 but if its the rom which is causing my battery life issues ill have to wave goodbye. Does this suspend process but happen on the weekly / nightly builds as well?
I was having horrible battery life as well. I froze some apps that I downloaded from the market and that helped a little bit but what gave me 20+ hours of battery life is the new UK orange Radio that has recently been released. I wanted to flash it since I am using an Orange UK phone and see if it improves my wifi connection, etc....
Reddy flashing a radio appropriate to your device and see if it helps.

Battery Life Rom REALLY Needed

Hello all
I have been roaming around XDA for a very long time now and I finally made an account because I simply cannot find an answer. I have a samsung vibrant and not the 4g nor can I upgrade(long story). I use my phone when I need it and i text alot. But lately my battery life hasn't been any good, I've tried reconditioning and the whole bit and nothing seems to give me my needed battery life. I am currently using ICS passion 13 RC1 and it works great, when Im not doing anything -.-; When I use it like for the internet or text a lot it drains. I got to 48% in 2 hours one time and thats with limited background processes. I know ALL about the keeping background proccesses and data using apps down so I hardly have any apps installed, which is very irritating at times, I dont even use the facebook app for that reason. I tried many different roms and it seemed Axura had done that best at one point but it was taken down or is no longer supported for whatever reason so I am now in search for a rom that can get me through the day. I text a lot and web browse occasionally. I dont have wifi so i cannot use that to save battery life while surfing so thats out. I would appreciate all the help and will try every rom if i have to lol XD
I appologize for the long message but I am so tired of hesitating to use my phone as a smart phone.
I get good battery life on the ICS Euphoria ROM. Your battery could be shot, you might try replacing it.
Any of the 2.3 or newer roms are going to get bad battery life. Fishmanmod's updating of Bionics has been very smooth and getting great battery life for me.
I find that battery life between 2.2 and ics is pretty much identical for me as long as there are no wakelocks preventing deep sleep. I'm currently on CM9 nightly w/ glitch kernel and deep idle enabled in nstools and have no battery life problems.
You could also look into getting an official 1800mah battery if you really need more juice
ICS Slim hands down the best.

Your issue is Passion. That ROM chews through battery worse than any I've ever used in the 2 years I've had my phone.
Sent from my SGH-T959 using Tapatalk
Its not just your Rom, I am on the CM9 nightly and noticed ICS ate my battery by noon today. I was down to 3% from 7am. Granted I am toying with it a bit more but I was still at work so I couldnt use it non stop and I wasnt even watching videos or listening to music on it. I have updated the kernel to SubZero 34 to see if that helps.
Chances are, your battery has lost some of its ability to hold a charge. I recommend buying a new OEM battery, chances are it'll increase your battery life by a good two or three hours.
So far, I haven't noticed a significant variation in battery use in various ROMs, I've found battery life to be more determined by the kernel.
Sent from my SGH-T959 using XDA
On a side note, I destroyed my screen by stepping on it a few weeks ago. Ordered a new AMOLED screen (not the LCD knockoffs) and battery life did in crease by about 3-4 hours. Same OS, same battery.
So I think some excess drain could be caused by the screen, which might explain why some phones had such poor battery and others don't. I also no longer have the "graying/shadow" issue that plagues some of these phone.
So far ive had the best battery life with ICS passion RC2.1 and my 1800mah anker battery
Since flashing CM9 and then putting on the SubZero kernel (34) I did a full charge and decharge to test and got 12+ hours on it with my normal use. So I have to say SubZero kernel really helps out if you are on ICS.
I f you dont mind going back to a 2.2 rom I would suggest trying bionix 1.3.1 fishmanMod or Deranged9 fishmanMod alpha 1 both get awesome battery life especially when mixed with juice defender.
I was also using ICS Passion and noticed a significant degradation in available battery life. I have three batteries so I'm confident it was the From. Until then I had been using various Froyo rooms and all seemed to have better battery life than ICS. I personally felt it was more likely to be your kernel choice that would impact battery life. I just switched to the SLIM ICS from and I gave been very impressed with both the battery and the responsiveness. Same quadrant scores as Passion but it feels so much faster

If you r searching for nice n smooth rom try

another thing you can do while flashing wipe battery stats only once....then reboot to normal drain your battery till it reaches 1% charge it full widout any interruption and when it reaches to 100% unplug it and do the calibration from any software available in the market I use Battery Calibration Professionals

repeat the process for atleast 3 days in a row and you will feel the difference..hit thanks if it helps
@OP ICS is simply not battery friendly. You're going to want to use froyo if battery life is that important to you.
Or you can build a battery friendly ICS rom and let us know how it all is
The later builds of Cyanogenmod9 I have been on the stock kernel and its going all day with moderate use without battery issues.

Bionix Fishman Mod is the first custom ROM I've ever installed on my phone and it's battery life is AWESOME. I recently added an 1800 mah battery and I've had 24+ hours on one charge with moderate to heavy use. The ROM itself is smooth as glass and no glitches to speak of.

I just installed bionix-V FishmanMod Final 3. Fingers crossed. I don't mind switching back to 2.2 as long as I have better battery. However I did notice when I reinstalled ICS before going to bionix that just factory, not even logging into the market. I got 1 day and 7 hours of battery life, granted I did not do much but text occasionally and some web browsing here and there. Is it possible that the android market is constantly checking on stuff or there is some data being proccessed constantly? I do live in an area where my signal is not great for 3g like 1-2 bars.

Alright so after about a day with the rom, I noticed it's just as bad. I am still getting battery drain and yes I have a new battery in so it is not that. I unplugged it from around noon, did alot of working on it with reflashes and little bits of texting and mostly just scrolling around the O.S. im now at 44%. its been about 5 - 6 hours.
Although I have been switching the battery between 2 phones and their battery meter is very different. like a 5% difference so that may be confusing it. Will update.

Jellybean Battery Drain Discussion

Now, I know that we have a "All your JB discussions here" thread, but I think that this one is a rather specific issue and hence should be discussed in a separate thread. I also know this post is rather lengthy, but please read and give your opinions as it's important.
If you look at the last 5 pages on the JB discussion thread, you'll notice that lots of people are complaining about the battery drain due to wifi. The gist of it is that if you forget to turn off wifi before turning your screen off, then you'll experience a battery drain of about 5% an hour even though you're not doing anything with the phone.
I can vouch for the wifi battery drain issue. After flashing DLJ4, doing a factory reset, doing several full charge cycles, etc. here's what I can say:
On ICS, battery drain when the screen is off is the same regardless of whether you leave wifi on or off. Approximately 2-5% overnight
On JB, battery drain when the screen is off and wifi is off is the same as ICS. But if you leave wifi on, it drains about 2-3% an hour.
General battery use on JB otherwise is the same as ICS
It's pretty obvious. You don't even need to use apps to monitor battery use. Anyone can easily tell that there is something about the wifi causing battery drain.
So there are 2 things to note:
1) Wifi strength on JB is much stronger. For example, I could never connect to wifi from the 2nd floor on ICS (the modem is on the ground floor; it always shows poor signal and gives the "authentication error" when I try to connect), but now on JB I can easily do so within seconds of turning the wifi on. And this result is consistent each time I try.
2) With wifi on and the screen on at the same time (eg: when browsing), the battery drain is similar to ICS, ie approximately 1% every 4 minutes.
Point (1) seems to imply that the wifi strength on JB is stronger, and maybe the frequency used is higher. This seems like a pretty good explanation for the battery drain, until you consider point (2). Point (2) seems to indicate that the problem is not in the wifi frequency, as battery drain during screen-on time is similar (you would expect it to be higher), but there is some other explanation.
So my idea is that the wifi is indeed stronger in JB but that doesn't affect battery drain significantly. Instead, the problem lies in the fact that wifi management on JB is just bad. On ICS, when the screen is off, the wifi signals are probably "weakened" significantly, for lack of a more technical term, but on JB it remains at the same "strength" as when the screen is on. This is probably what causes the battery drain.
I'd like to use this thread to see what everyone else thinks from the experience on stock JB roms. And of course, if we can properly identify the cause, surely someone would be able to fix it.
Update 1: Alright, so far it seems that only those on stock kernels have this problem. Those on Siyah kernel appear to be unaffected. I'll test it out soon, and see if it can be a temporary fix for now.
Update 2: So I've been using Siyah kernel 1.7 RC1 for nearly two days now. While the battery drain due to wifi is reduced, it's still not as good as it was on stock ICS. And this is even after I flashed the "better profile.zip". Also, as a side note, the overall battery consumption on Siyah isn't significantly better than the stock kernel. But at least wifi battery draining seems to be less. Do continue posting your experiences so we can find a more viable solution.
Update 3: Over the last few weeks I've tried out DLJ1, DLJ5 and the leaked Rom with multiwindow (can't remember the Rom name). Anyway, from my experience, and from the collective opinions on people who posted here or in other battery threads, it would seem that the WiFi battery drain persists in all these jb roms. The only solution I've had so far was to use Siyah kernel. Some people report that custom roms work too, but I suppose if you're reading this thread it means you're trying to fix a problem with stock jb.
Wifi battery drain is bad on my s3 too. :crying:
I thought it was just some wakelock issue. hopefully the next jellybean update will fix this
I'm on the latest DLJ4 and I had wifi on last night. I unplugged my phone from charger at 3:00am then woke up at 6:30 for work and in that 3.5 hours I had only lost 2% battery, the whole time wifi was running.
Maybe it's kernel related, I'm running Siyah 1.6.8 and I don't seem to have a problem.

I'm on stock kernel. Perhaps I'll try out Siyah kernel, but still there a quite a number of us facing this issue, as you might be able to tell from the original JB discussion.
I've been on Omega since version 25 (now on 31) and I have 0.9% per hour battery drain with WIFI on. I've used BBS and found all of the main drain causes on my phone and stopped them. For instance, I have location services turned off and even disable\freeze maps when the screen turns off (I have a tasker widget to defrost and open it when I want it).
On my phone the OS doesn't have a problem with WIFI battery drain, but various apps and services did until I sorted them.
Edit - my drain is the same despite whether I run stock kernel, Phenomenal or Siyah.
I'm on siyah 1.6.8 and have no decreased battery life.

Well are you sure ? please answer My problem is the WIFI speed su** it always shows no bar or 1 bar all the times and speed is horrible after seeing your comment i think JB update is worth a shot
Maybe we need to add:-
These problems are only on stock jb roms, not flashed kernels or custom roms. A large amount of people on stock firmware on jelly bean have this WiFi drain. Its very obvious on my phone, with WiFi on and screen off, I get around 4-5% drain, with WiFi off and screen off I get about 0.5% drain.
And I thought that this problem on my phone only ... I wanted to do a factory reset, but you say it doesn't help, so no point trying.
With the JB benefits, there are still annoying bugs.
1. When accessing a Settings tab, notice how it opens. There a chubbiness in the Settings app. (tried to clear data etc etc ..).
2. TouchWiz Redraws very frequently.
Other than that, I can't see any problems with the Official JB.
I don't get drain Lj4 WiFi on overnight max drain 2-3 %

I know these aren't methodical tests, and they're still quite subjective. But it's pretty obvious to most of us that the wifi is stronger. By the way, what do you mean that you don't see that sort of drain? On ics or jb? Because on both ics and jb, my battery drains about 1% for every four minutes of browsing and I find that normal; pretty good even

I'd like to add that after I installed the stock jb it wasn't the WiFi I had a problem with it was my network connection with virgin as my signal was very low, about only two bars and my s3 used to get very hot when it wasn't doing anything.
After I left my screen off overnight and checked bbs I found that the main problem causing battery drain was losing connection and bad connection and my s3 got hotter the more it charged.
I tried the Shiyah kernel and flashed the even more battery zip I've notice that I now have a full connection and it hasn't dropped out yet and my battery is draining very slow and my s3 is very cool which I am really happy about.
Edit:After a full cycle the quad core seems to be draining less, seems the Shiyah Kernel is the best Kernel for battery life with Jellybean

Yea got the problem too ...if I use my phone on charge it slowly (I mean really slowly) charges...and it takes twice as long to charge my phone. When I returned my phone to stock (ice cream ..etc) it goes back to normal.
But wanna thank this thread hopefully changing kernel will help

I've just noticed something after using stweaks, if I change to dual core my battery drains slower and the Celsius of the phone is lower but if I have it on quad core my battery drains really fast and the Celsius is much higher.
I read somewhere that it's only the international versions of s3 that have bad battery drain and the other versions use dual core, not sure if that makes a difference.
Also noticed after changing to dual core my s3 only lost 4% over night, I also undervolted the battery a bit.
I installed the wattage widget to see the differences.

How about folks running stock DLJ1/2?
I had flashed DLJ2 French stock version previously and I feel I had better battery at that time than DLJ4 UK unbranded JB (which I am on right now).
And I dont think we are getting enough complaints about battery life from folks who are running versions other than UK DLJ4 ROM!

[Q] Help! Horrible battery life!

So I got my Nexus 4 on April. I was super happy with my phone and already knew how to root and install custom ROM's. So throughtout the last couple months I've installed custom ROM's and kernels. Well with several ROMS's and kernels my phone began to overheat a lot so my solution was to install another kernel to see if it worked. For example: the Franco kernel overheated my phone a lot and I asked myself if it was normal, I still don't know if it is. Since August, I've noticed I have horrible battery life. I have to charge my phone constantly frequently and can't use it a long time. So I flashed my phone to stock to see what happened with the battery and it stayed the same. So I don't know what to do. I'm not sure what damaged the battery but I think it might have been the overheating or all the ROM's and kernels i've installed. Please help!

its not overheating. if it overheats, the phone will shut itself down. what is your average cpu temp when the phones idle? battery temp when the phones idle? most likely its your own setup. apps that open in the background, and apps that sync. it can also be your signal, as lower quality signals drain battery fast. anyways, do you have many apps with notifications? do you have facebook installed? greenify is a good app to start with, for controlling your apps that is. the key to good battery life is controlling your apps, and setting up your phone to not waste battery.
I would highly recommend backing up all your data from your phone to your computer and flashing the google stock image through fastboot (there are youtube videos to walk you through that if you have never done it before). If you still have severe battery issues after that, then you can confidently say your battery is damaged.
It's normal for the phone to get hot.
Try other kernels, personally stock & Franco both have me terrible battery, HellsCore is giving me great battery though.

When the phone is idle, it gets to 31°C and on normal use (facebook, instgram) it gets to 38°C. I actually have good care of the battery. I always have Wifi, Bluetooth, NFC, GPS and Sync off. And I have Automatic Brightness. And I don't have much apps with notifications.

I actually have already done that. I did throught the Nexus Root Toolkit. And it didn't help. And i'f I replace the battery will that solve my problem?

I actually used Faux123 and it gave me great battery life. But when I updated to PA 3.6 or 3.9, I installed it but it actually sent me to a weird yellow error screen when I tried to boot up the phone, so I had to flash stock to the phone to restore it. Which ROM that works with PA 3.99 would you recommend for battey life?
Like others have pointed out.. Your phone wasn't over heating. The N4 has a glass back. Glass is able to move heat very well pulling of from the inside and irradiating of outwards which will make it feel hot. My battery temp runs me between 80 and 110 degrees Fahrenheit.. (Or between 26 and 40.. Something C. ) never had an issue..
As for your poor battery life.. What Lind of screen on time are you getting? What a full charge last you with said screen on time.. Do you make or take a lot of phone calls?
It all comes down to usage .. Your screen and voice calls will obliterate battery. among other things.

those are normal temps, some might even be jealous of them. the ambient temp also plays a role in your phones temperatures.. the warmer its around you, the warmer your phone will be/get(or vice versa).
as someone pointed out, voice calls impact the battery greatly as well. calls take a lot of battery juice. also, facebook is a know app that like to misbehave, and take your battery, when not even using it.

I've never used PA, but give HellsCore a shot.
