My Battery Percentage Increases...

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.

Drastic Battery Drain overnight

Hi! My friend's tab is experiencing drastic battery drain overnight. from 60% - 20%. wifi was off, no messenger running. only email push notifications. all running apps were closed.

If you just upgraded to ics, try a hard reset.

Its still using Honeycomb. We have not received the ICS update. are there any apps that can monitor what apps or processes is sucking up the juice? Preferably if it doesn't require root.

Have you tried checking battery usage? There you may see what's using your battery. Otherwise, there might be a hardware problem.

ICS definitely improved my battery life..
I was having terrible standby battery life on HC until I turned on airplane mode. Even without a sim card the radio was killing the battery.

If you don't have a sim card in then this is what causes battery drain. This problem is on all Samsung tablets that i have.

Theres a sim card inside. i have the same tab but i do not experience such drain overnight. monitored my set for 2 nights it only dropped by 2 to 3%.

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.

have you been fully charging and fully discharging your phone?

What app did you install? Did you install a new rom? what rom are you on? My guess would be a rouge app. Have a look in the battery usage graph or get spareparts and look at the things that are keeping the phone awake.

I would suggest you download CPU Spy to see if an application is preventing your phone from entering deep sleep mode, for example. You may have a lot of widgets refreshing way too often, as well.

The only widget that refreshs at my home screen is SetCPU, in order to monitor the Temperature, but i will try that app in order to check whats going on thanks.

Ok finally I've managed to see what was the problem that was causing such battery drain/loss... The problem is that i wasnt full charging/discharging, now the battery seems to be working fine. Also I've check cpuspy and nothing is interferindo with the deep sleep.. Thanks for the help

Never fully discharge Li-ion batteries.

But is not fully discharging, under %15 damages battery? And also i put from batter over %95 because after %100, it waits until it drops and again charges if i forget there.

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.

REBOOTED - nothing, drain battery like hell, lose about 30-40% in 5 hours...
I woke up with 15-20% battery drained... wtf guys ?
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.
