I've noticed lately that my battery has been draining pretty quickly, but I've since chalked that up to an old battery that just needs replacement. But I noticed today that my battery ran out and my phone shutdown, but I went to charge it and immediately turned it back on and noticed that it read 50% charged. What is happening here?

As you already changed the Battery, I assume you'd have done calibration as well. If not, please consider doing it.
I have the same problem but I suspect that is because of battery, I'll be changing that soon and will write back
I'll leave this here in response to the advice to calibrate your battery

To get the best life out of a charge, flash a ROM on a full charge and then let the battery die and fully recharge it.

Ok so these last couple of days I've been having the strangest problem with my vibrant. The battery litterally sucks it self on the charger. For example, today at 3 in the morning I woke up to find my phone charging at 71% I was like ok good. Woke up at 7 and the phone was completly dead! It looses power on the charger. At first i thought it was the battery so i switched it. And whattya know. Still the same problem. Then i thought it was the usb port since ya know samsungs port sucks ass so j get a new charger and nothing. Let me remind you tthat this is a recent problem. Any body know a fix to this?

Test your charger. Try usb charge from pc. With a different cable to be sure something is not crossed inside.

The battery should not drain like that period not even cm is that bad
Sent from my SGH-T959 using XDA Premium App
My point is nothing to do with rom or phone but rather the charger or cable my be damage and causing short that drains the battery. Hence the suggestion to try other cables and charge methods to eliminate the possibility of this being the culprit.

Does it also fail to charge if the phone is turned off? If it charges while off then perhaps its a software issue after all. If not then the charge/usb port might be bad. How are you charging the battery between posting?

It shows its charging. But it'll go from like 11% to 0% in like 10 mins. And yea it charges with the screen off.

Have you tried to backup and re-flash your phone? Have you tried a battery calibration by wiping the battery stats? My advice *having never encountered that issue* would be to save all your data, make a list of the apps you use regularly and re-flash the phone then manually re-download each app and do not restore anything. if all goes well and it charges like normal then your set and can if you wish restore your old data and/or apps 1 per day till you notice the problem, return if it does.
I did just that. Reflashed a new rom and less drain but its definatly.

My next advice would be to try stock 2.2 for a day or so and see if it has issues. then if its ok try a new stable version of cm7 or miui * different build than previously used* and see if the problem returns.

Ive been thinking of cm7 but the battery life is driving me away. I was able to charge it till like 40% then i unplugged it by accident and I plugged it back in and BOOM battery drain. Its at 0% and will not rise.

If the phone gets hotter than 120° then it wil stop charging and actually dicharge. Make sure your not overcloking or ajything.
My advice on which rom if your not set would be to use trigger. I moved to trigger a long time ago after one of my bionix flashes didnt work quite right and have not looked back yet. I am currently on project v with trigger theme which is a little more like stock but with tweaks than a fully custom rom.
Ok so I got it to charge too 100% overnight and I unplugged it and it went down too 37% instantly. -__- just started working today and this isn't cool. I also left it by a fan so it wasn't hot at all.

In that case I would be sure to flash back to stock clean and then go to a different rom, I suggest Trigger 3.2 very stable in my experience, and charge to 100% and do a battery calibration. Trigger comes with an app to calibrate the battery and be sure its fully charged.
I'm currently running cyanogenmod 7.however my battery percentage changes irregularly. It can be 50 then all of a suddejt jump to 30. Don't know what is going on.
Anyone have a solution. Cheers

do a full wipe and reflash the rom
charge to 100%
than use a battery calibration tool
see if it works
otherwise, full wipe and another rom
When I put the phone on charge the percentage doesn't increase however it shows the charging symbol

Did you ever leave your phone in a very hot place such as inside your car?
I've had the same problem after leaving my DHD in my car in the blazing hot sun, and it cooked up the battery which stopped providing correct battery info to the 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.

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.
Hey, can someone explain me this?
I charged my phone to atleast 24% begore i went to bed cause last time i tested battery when i sleep, the battery dropped 20% in 10 hours, but now i charged it to 24% and when i woke up today it had slowly increased to 32%... what the heck? Can someone explain this to me?

wrong sub section but in answer, my s2 done that all the time almost after flashing a rom.
could start off at 100%, flash a rom and itd be at say 25% then start building up again toward its correct %. no biggy, its kinda normal :good:
Wrong section to post this but this problem also happens on my s2, it is something wrong with the fuel gauge. Just do regular charging and discharging and it should return to normal.

Your battery has a problem. Cause of overcharging.
Sent from my GT-I9505 using xda premium
If you've flashed a new rom, often the history of battery values and voltages get messed up. So its not really sure what percentage of battery is left when the battery is at X volts for example. Usually a complete discharge followed by a full charge should recalibrate the battery monitoring.

Try a few complete charge cycles. Hopefully it should fix itself coz its not really uncommon.
