Hi,
So I was charging my phone turned off indicating 47% then I pulled the charger and turned it on.
Suddenly the battery indicates 57% after boot.
I am planning on deleting the Batterystats.bin on 1% before the battery drains then make a full charge while phone is Off.
Is this okay? Healthy? Not Good?
Thanks in advance!
Deleting battery stats doesn't make a difference on this phone. Although some people swear by it.

I am on PunkRom and I usually don't charge my Triumph until its almost dead. So I am around 20% on my phone and when it gets around 15% It dies, well shuts off on me. And I'm like, well, is it because this Rom is programmed to be this way or is it a tweakable bug that it's having? Or maybe something I forgot to read. Anyone else having this issue?
Thanks.
And all Props to the person who made the Rom I like it most of all.

What you want to do is charge the phone full by charging it while on tto 100%, then unplug it, turn it off, and plug it in until the red light turns green. Boot into cwm recovery, and go into the advanced folder. Wipe battery stats. This should fix your problem.

Weird enough. I can vouch for Punk ROM not being the source of that issue, it could be a b_randon14 tweak... but even I wouldn't be able to say what Or where as even it seems relatively stable.
....that much said, do what the person above said. Wiping your battery stats on a regular basis is unwise, but in a situation like this it makes the most sense.
Also, for a generally longer battery life, charge once you reach fifty percent or lower.
hi guys. I'm having a pretty simple problem - my phone will charge up to full according to the battery icon when it's off, and when it is on it says charged on the lockscreen, but it says 96% on the battery widget that I have and as soon as I unplug it it drops to 96% on the lock screen. I know this is a problem common if a tomorrow was flashed with a not full batt, but I haven't flashed anything. I have only rooted. Deleting batterystats .bin didn't seem to do anything.
Thanks in advance. Hopefully it's an easy fix.

No problem for you. It's made to charge up to 96% to "extend battery life" or whatever. Don't worry about it.
Some kernels provide a cosmetic fix that shows 100% charged, but it charges only to 96%. Another alternative is to bump charge the battery (explained here on the forums) but I don't see why you would do that. Not much to gain anyway.

it's safety feature in order to protect battery
That extra 4% - not that significant. I've tried to bump it to 100% (have to wait significantly long), but not much gained in term of extra uptime.

Ah cool. Thanks for the info.
It's not like that extra 4% is a big deal, I was just curious if i needed to recalibrate or not.

Nothing to worry about. Just enjoy your NS with ICS

and try installing Nexus S charger app in the market, got 100% charged on my Nexus S 4G !!
acutally , for Li-ion battery , if you everytime drain it to 0% or charge it to 100%, would damage it and short its lifetime...
If you wan't charge 100% use a custom kernel or Rom.
Exemple : Peter Alfonso : http://www.peteralfonso.com/
I've had the Galaxy S3 for a few months now...I haven't changed anything lately and never had this issue before!
Well...For the past 2 days, my phone drops from about 18-20% battery life to empty, nothing in-between...It just suddenly turns off and I can't turn it on until I put it on the charger...When I turn it on, the battery is completely drained and it's gotta charge before I can turn it on...It even shows this straight drop in my battery stats chart!
Please help...Thanks in advance!
Sounds like you just might have a bum battery. If you've got another one try experimenting with it, if not that's what I suggest. See if a new battery fixes it, if not I'm not sure.

I had this issue and downloaded Battery Calibration. This happened to me a few days in a row. I recalibrated after a full charge and issue has been gone since.

Battery dead
Same thing happened to me today, calibrating the battery seems to have fixed it, for me anyway. And if i'm not mistaken it doesn't actually calibrate the battery, it just aligns it with the ROM so that it reads its level correctly. Someone correct me if that is incorrect.

Thanks guys, I'll try that too!
Went to bed with 90% battery and when I left the house found it at 19% or so any idea what's up?

you are right
its because of background data! Wifi takes a lot more than sim network! Always turn background data off while leaving the phone! That's wat battery savers mostly do

Depends on the network I suppose then because for almost everyone I know, wifi uses much less power connected than any 3g or 4g network

I leave mine on all the time and have great battery life. Wifi also uses way less power than cell. So with that out of the way the OP has some issues for sure. However it's impossible to help you with the info you provided and that single screen shot. Your network strength isn't the best but shouldn't drain that much over that time. Phones awake every now and again but nothing out of the ordinary. Get BBS and see what's up.

Thanks. I'll check it out. 29 hours on next charge so could be an isolated fluke.

Varied results for me. 1day its 5% drain. The next it was 30% and another was 90%
Hi all,
I got a great Nexus 5 over Christmas and have been using it quite happily with the exception of terrible battery life, getting on average 3 hours on screen time just emailing, texting, redditing, and facebooking. I'm seeing massive drain, even sitting idle overnight (~20%) on wifi. I have auto-sync off, all notifications on apps off, brightness set at ~5-10% fixed, and location on battery saving.
I've asked around and tried remedying all these problems by changing to ART, rooting my phone, installing wakelock detector, BBS, and Greenify. Greenified almost every app, minus the messenging apps. These steps didn't do anything for me, so I installed Franco kernel, which also hasn't done much for me either. I got rid of Facebook, which didn't do much (seeing a trend? hehe). Finally set my phone into safe mode last night to see if battery was just as bad, and lost 23% in 8 hours (still a far far cry from the whole sleep like a baby), so it's not some rogue app issue.
Now I've read a number of things related to terrible battery life on 4.4.2 and that the best remedy is just a factory reset. What does that do exactly aside from wipe out data? If I just end up reinstalling the same apps, and going back to my old settings, won't I get the same problems again? And if I go ahead with a factory reset, should I be sticking with Dalvik or ART? Should I try flashing back to a 4.4 image provided by Google (can I even do that?)? Or should I be returning my phone to get a replacement?
Many thank yous in advance for thoughts and sorry for any noobish questions
Sometimes settings existing before an upgrade conflict with the upgrade causing things to act incorrectly. I would always recommend a reset after an OTA but most simply won't do it.

battery life is dependent on how you personally set up your phone, what apps you chose to install(facebook is the worst app for draining your battery. itll drain it even if you never open facebook), the way that you manage your apps, and very importantly, battery life depends a whole lot on the quality of your phone and data signal.

That makes sense. Would my unlocking bootloader/rooting my phone count as my factory reset after updating to 4.4.2? Or should I do it one more time after having switched kernels? Thanks!

Totally understand that. I thought that doing safemode effectively just makes all third party apps disabled and thus my phone is about as stock as can be then? Would this be saying something about the quality of my battery then?
Unlocking bootloader resets, yes

a. it factory resets when you unlock the bootloader.
b. factory resetting after switching ketnesls makes no sense. you dont even have to wipe anything for flashing a kernel.
c. your setup, your apps, and the quality of your signal is most important for battery life. if you factory reset, then set your phone up the same way again, and have the same signal quality as before, you will just have the same battery life as before.

I guess then my question is then, did my experiment in safe mode actually tell me anything? I have nearly everything off, my settings should techncially reflect a more power saving state, and I figured a safe mode overnight at home, on my own wifi network, would tell me if it was something with my battery or something with my apps... am I wrong?

i wouldnt really call it a power saving state. its more of a "safe" state, against badly behaving apps. all your normal processes are still active. anyways, 3h sot is normal, can be better, but can be worse. your signal will have a huge impact here. some people in some location will never have 5h sot, no matter how hard they try, if their phone and data connection dont support it. and again, that facebook app can be a battery slaughterer just by itself. i uninstalled it two plus years ago when i didnt open the app for over a month, yet it continued to drain my battery(averaged around 7-15% battery use, one day it used 22%, so i uninstalled it from all my devices and have been happy since).
