I just got my nexus 4.
Last night I charged the phone completely, disconnected if from charger and turned the phone off.
This morning when I turned it on the battery was drained 15% down to 75%
Does anyone else have this problem?
Defect with phone?
Thanks for help.
You have to let the battery settle and let the battery stats calibrate. The % that you had after rebooting is what you really have. The first time it wadjt showing the right amount.

He said he turned his phone off...
I don't see how it can lose 15% if it is completely shut off. That's weird.

Then when he turned it on, he "lost" 15%. Like I said in my post, what it said before he turned it off was wrong. He didn't really lose 15%. It was just displaying the wrong thing.

You might have some apps running in the background that is preventing your device from going to deep sleep to conserve power. Check what's running in the background when your phone is off. You can use better battery stats app to check what's consuming your battery level.
Are your running a custom kernel? I've heard of a few cases with kernels where even though the phone is sleep and screen off just touching the screen will cause battery drain.

I'm guessing you either meant it was at 85% or drained 25% down to 75
Either way this is common on a lot of phones now due to the way the battery gauge works. When you turn your phone off then on it doesn't always remember where it was so gives a value and then if it's under where it should be it soon recalculates and can either starts going up or stays on the same value for a long time. This has happened on both my old SGS2 and also my N4 for example this morning while my phone was being drained by the FB app keeping GPS on, I turned off location access and then restarted my phone which dropped a few extra % and then sat for a good few hours at that % even though I used my phone.
Moral to the story is don't always take what you see as true, give it time to settle and see how it goes over a few charging cycles.

First of all, I know what most people will say: wipe battery stats and condition the battery, but I'm too lazy.
So recently I've been noticing that sometimes my battery charge percentage goes up rather than down. For example, tonight I put my phone in my pocket at 18% battery left. I watched some tv and checked it again ~1.5 hours later to find that it was now at 32%. I've seen this happen on occasion before, but never such a significant jump.
Anybody have any clue as to why it would do this? Other than the fact that my battery stats are needing to be wiped. idk just seems weird to me

Sometimes that happens after a random reboot, where when it comes back up, it has "dropped battery." Then it realizes it isn't actually that low, so the battery meter will climb till it actually equals the battery. Then it'll start dropping again.

That was happening to me on Clean GB, I reboot my phone every 4 days or so and my percentage would drop significantly after booting back up, then start increasing. I've never wiped my battery stats. I'm using another stock-like ROM so I'll see if it happens again.

When you reboot do it while plugged into a charger and that won't happen. It is a glitch in CWM and battery stats.

"Conditioning your battery" after wiping battery stats takes nothing more than regular usage of your phone. All the people that say you have to do all that stuff after calibration are just recommending it because it causes your phone to adjust faster.
Just charge it all the way and use battery calibration to wipe stats. Your battery life will take a few days of use to improve to good levels, but it works and you don't have to do anything other than what you normally do with your phone.

Yes, I have to agree. This has also happened to me. I have actually had this happened when I turned my phone off one day. Before turning it off it had 60% battery, after a minute I turned it on and it said 20% battery. Also, has it happened to you that you charge it leave a couple of hours and when you unplug it rapidly falls to 70% or less? LOL! But it is nothing a full charge and batterystats.bin wipe wont fix.

Wiping battery starts has nothing to do with reported battery percentage. Similar results can be obtained by setting your phone face up on the coffee table, watching any random show on tv, and doing Zumba for 30 minutes. In other words... none.
Battery stats, which is only a list of the apps that have put a demand on the battery, is already cleared each and every time the os is rebooted

This is what I have read on the XDA forums and it has worked for me.
Completely charge your phone to 100% (Full battery charge) without unplugging. Once it is charged, without unplugging it, reboot to recovery and wipe battery stats in the ADVANCED section. As soon as your wipe it, very quickly unplug the phone. (as fast as possible). Once you do this, reboot your phone and completely drain it to until it turns off and you cannot turn it back on unless is plugged. Once it is drained charge it completely full withot unpluggin it or turning it on.(Best time to do this is at night, since you are probably not going to use it while you sleep). After that just use it daily. You have to give it a couple of days so the battery syncs up. Hope I helped out!

No offense, but what you have read is incorrect and is rooted in a misunderstanding about how the os and li-ion batteries work.
1. Wiping battery stats does nothing pertaining to charge indication. The file cleared is an already blank file that lists nothing more than a list of the apps that have consumed power. This file is cleared by the is on every reboot already.
2. Completely draining the battery shortens its serviceable life.
Any "results" that are seen by doing the above are merely attributable to the placebo effect.

wow guys are you all serious??? i lose around 10-15 percent overnight man
Dude.. My phone was on 60 percent at 6pm once when I slept... Next morning at seven it was off... Wifi off data off.. All **** off... I dint even get a call or msg... Definitely not 1 percent I guess...
If I leave data and WiFi off, about 2% to 10% but that isn't usual. When I am home, I leave WiFi on and that gets my currents and YouTube video preloaded. 15% to 20% Max. I rarely leave it to charge overnight.

I kill all apps, turn of data, wifi and etc, still nothing...
BATTERY STATUS - messaging use 84% of battery... wtf ?
To all of you having problems with battery drain, you should know that last Google Maps update messed up the deep sleep state of the system.
I´m running Carbon ROM, but also tested with other 2 ROM´s and the results were the same, around 20%-25% battery drain over night.
I read that disabling "Reporting Location" and "Location History" under Location settings in the Google Settings app(the one with the green icon) helps a little, but still is an issue.
With these settings disabled, I get around 5% battery drain over night. Although the wakelock has decreased, is still there waking up the device. Already reported to Google to see if they can do anything to fix it. The wakelock appears as "Android System" or "Google Services".
Before update I had around 3% battery drain over night(around 8 hours) with WiFi.
Hope this helps.
:fingers-crossed:
As a battery life druggie, I get 1% max. Regardless rom. Usually wifi off and 2g data on. (wifi on is bad for HUMAN DEEP SLEEP).
A not sure useful or not hint, set pm.sleep_mode=1 in your build.prop
Disable everything you can think of. Wifi, gps etc.
Uninstall bloatwares, replace with downloadable ones, use greenify to freeze them.

You probably have a battery drain. Try this: charge your battery till 100% before you go to sleep, leave it in standby over night and see how much power you loose. My 9005 goes from 100% to 96% in 9 hours of standby, which is pretty good. If yours loses much more, you probably have an app keeping your phone awake. A first check would be the location tracking settings in Google maps. Switch location report and location history off. They are famous battery drainers.

Wifi. I was pleasantly surprised myself I didn't try heavy screen usage yet, but with normal use including telephone calls, navigation, note taking etc. I get through the day easily without extra charging. A normal day for me lasts from 7:00 till midnight, with 30% battery left at the end of the day.

Not to rub it in, just to show you that a good battery life ís in fact possible: on 4G/LTE the battery power went from 100% to 98% in 2,5 hrs.

I purchased a nexus 7 recently,updated to 4.3,locked and unrooted as of yet. I currently have 2 user accounts active on it. Since my first 100% charge, I have been getting tacky battery life. I follow the 100% charge and discharge till 1% method. Overnight with WiFi on and all apps closed,I'm getting a drop from 74% to 57% . Looking in the battery stats doesn't help as it doesn't show any unusual ongoing background activity. I'm also getting around 6 hours Screen on time,I could never exceed this mark. I only have the customary Google apps,Facebook,Twitter, instagram,pulse,and 3 games installed. What can be the reason of this ?

Those apps keep running.. Also some third party apps push ads and also turn screen on, which could drain battery..
For better battery life, you can turn wifi off if not needed,.

You might well try the app Better Battery Stats, and see what it believes is keeping your tablet from going into deep sleep. 9% drain overnight is not terribly excessive -- it should be more like 5%, I guess.
My 2012 nexus 7 had 51% before I went to sleep last night and when I woke up this morning it was completely dead. I didn't even get a charge icon when I plugged it in to charge. I had to leave it for an hour then tried again and it fired right up.. Hope I can see what's causing the drain with better battery stats

I was using mine once in the morning,when the battery hit 4% it suddenly shut down. I tried to charge but the battery icon wouldn't show up.
