Notice battery issue recently.

So im at a convention thisweekend and its been a while since I flash my rom to 3.2 freshbaked. This weekend I notice straight from 100% I was burning through most of it in 6-7 hour with out alot of usage. I took my phone out at 11:30 today and its only 4 and im already down to 36%. My battery usage shows 36% from system 22 from cell standby with 0 signal lost and 21 idle. Ill flash an updated rom when u get back.

flashed new 3.3.0 fresh and after a full charge i've left it idle for 2 hours and i've already drained 20% of the battery. That roughly 10 hours of doing nothing and my phones dead.

It could be some app you are using/installed.

I recently flashed Fresh and expierenced the same situation . My Android system was always the highest on the list . I removed apps and stripped it down , I wiped Dalvik and Cache you name it and the phone could sit idle and the Android system would be as much as cellstand by if not higher . I eventually just went back to stock Froyo with root . Android system now sits lower than cell stand by and phone idle

I'm using the newest fresh Rom with kings 9 kernel and set CPU. I never been a heavy user but I'm sitting at 19hrs and 43% I took it off the charger around 3pm Saturday and have not charged it since.

fresh 3.3, and netarchy's 4.1.9.1 fresh comp kernel, run your battery down to 3%, once there, boot into recovery, wipe your battery stats, and then reboot, once you reboot you may only get as far as the lockscreen before it shuts off, then either swap in a spare fully charged battery, or fully charge your battery with the phone turned off.

This is insane I'm currently Losing 1. 5. % a minute. Took it off 8 minutes ago and its down to 86 with 70% system usage

What is your signal like in the building? I had a similar issue when I couldn't get a good signal. The phone would last four hours just sitting on my hip.

IMPOSSIBLE battery drain........

im using gummynex rom, with the sgs-ns-ics kernel, and the battery drain suddenly became HORRIBLE.
i've used this combo before as well (kernel is on conservative/cfq), but never experienced this kind of drain. cant remember if it happened after updating or what.
1-2 hours of screen time, phone is DEAD. android os 50%+ battery usage.
left my phone unplugged overnight, and this morning when i woke up it was sitting at 40%, and it was 100% when i started sleeping. (6hr 30mins).
i used to get atleast 15hr, should i be changing the rom or the kernel? or downgrading the rom?
wifi = always on
3g/gps/autosync = off
good signal

Mix it up, try a different kernel... if that doesn't help, try a different rom.

You're kidding right? The exact same thing happened to me today! Gummy with matrix.
Down to 8 percent in 2 hours 30 mins.
I restarted, plugged it in and everything was fine.

Could be a hardware issue too.

happened to me as well. Updated to 7.7, less problems after tinkering

Try draining your battery to 0% (until it shuts off by itself). Then, charge it (non-stop) to 100%.

I had similar problem flashed new ROM codename + matr1x kernel
And battery only last 10hrs.
I drained the battery then fully charge and used battery calibration app then drained again and full charge difference was amazing got 22hrs . I left my phone all night with wifi on when wake up 98% .
It might work for you too.

With ICS, you don't have to delete your NS' battery stats, as it resets automatically once it reaches full charge.

I am using the stock 4.0.3 rom with air kernel 3.1....the phone is working normally with 50+ hours of battery time since its unplugged and it still is sitting at 22 percent....

[Q] Huge Battery Drain

I dont know what is wrong with my N4 but suddenly it started consuming very much of battery..earlier it used to give me battery run of almost 20+ hours with normal to moderate use but now with similar usages my battery does not even lasts 8-9 hours.
ROM:- Carbon (Nighly 19th September)
Kernal:- Franco (JSS r183 nighly)
Governor:- Interactive
I have installed both BBS & Wakelock detector...but there is no rogue app keeping my N4 awake..
As per my today's analysis
Battery lasted 8 hr 30 mins.
SOT(46min)
Voice Calls:- 8 mins
Awake %- 33% (rest of time deep sleep)
Usages:- Very less use (was at office whole day and phone was sitting idle at my desk)
And i have noticed a strange thing :- it takes very long to charge completely..Earlier it used to get fully charge in 2-3 hours..now its taking almost double of it.
Any ideas people...My N4 is just 5-6 months old..Is there any issue with my Battery..? I can not see back of my phone swollen or nething..
REally appreciate the help

Could be a battery problem but you might want to try simulating a battery pull you can do this by making sure you n4 is powered off and not on the charger then hold the volume up and power together for 60 seconds, reboot and see if theirs any change.

Any change as in battery % increase..? I did that but battery percentage remained same...? Do you thing there can be any issue with my rom or kernal installation..? Should I do a factory reset and install my Rom and kernal again..?

Nexus 4 Battery

So I have nexus 4 with battery that was bad it basically would die at 18% just shut off. So I replaced with new battery and I charged it right away to 100% and did battery calibration as soon as I unplugged it it said 79% every time then I plug it back it and it instantly counts and climbs back to 100% within min and once it hits 100% it fine it will drop normal I'm not sure if I shouldn't have done a battery calibration to brand new it like it remembering old battery now it does this every charge cycle it annoying.

There's absolutely no need to calibrate the N4's battery. You just don't need to.

What do I do now cause every time it shows 100% then drops to 79

Better put back the original battery and try this:
1. Leave your phone to turn off cause of battery drain
2. Immediately reboot at fastboot mode and leave it alone for some time, till it gets off again. This is the real point 0 of battery.
Now charge it till 100% without using it.
After that use it normally and inform is if IT got any better.

So I bought new battery this new battery won't hold a charge past 79% so I ordered a new one I f!ash Stock and Relocked Boot loader now when I get new battery in it prob gonna be dead should I charge it til 100% and another 4-6 hours after to get beat life right ... Then run it once or twice till it complete dead and charge to 100%

battery draining in seconds

Good evening people at xda,
From the past few days i am facing an issue in which my battery drains instantly like if i unplug my phone at 25% within 1 minute its at 17% and within 5 minutes it is zero and phone shutsdown. Then i remove my battery and put it back and the battery is again 18% and then again the same thing happens.
*I had made sure that no app is causing this immense drain
*my phone is not rooted
*Running lollipop
*N910G
Any help would be strongly appreciated!

New battery. Mine was doing the same thing. Got a whole new phone when I replaced the battery.

Didn't bother with the hassle. It was at the end of the warranty period and the batteries are so cheap these days. Got a two pack of Anker for about $40 I believe. Great company for chargers/battery packs/batteries.

Same here over here. I have an N910C and I get sudden battery drains. The battery starts jumping down from X% to Y% in seconds until phone shuts down. So, I connect my charger and suddely thr battery is 15% again. Sometimes I see that battery is 20% and I connect my charger but I doesn't start charging my phone, it is as if I started a battery countdown and instead of charging my battery starts discharging faster than the speed of sound. Other days I have 40% and suddenly 0%; phone shuts down. This is insane. Let me know if battery replacement solves the problem.

Also getting poor battery life and fast drain in seconds. Had 13% of battery yesterday, started Skype call and phone shuted down. Last night I had 27% and turned on the ultra power saving mode. Had 25% in the morning, turned the saving mode off and battery went straight to 7% and phone turned off in half minute. Should get new battery tomorrow, will update then.

Same as what I experienced last week. And I noticed the left side of my screen was lifting.... then I checked the battery and saw it bloated... I threw it away and used my spare....
