[Q] While plugged in USB battery shows fully charge when its not - Samsung Galaxy S (4G Model)

Recently when I have my phone plugged into the computer charging it will say its fully charge in a matter of minutes no matter how dead the battery is. After I unplug the phone it shows its true battery level, I have noticed that it still charges the battery if I just leave it plugged in, I just find it really odd that the system is reporting a fully charged battery. Anyone else experiencing this type of problem or maybe know of a fix?

Did you flash a ROM recently with your battery not fully charged? If you have then your battery stats are out of wack. When it says it is fully charged, just unplug it and re-plug it in. Continue to do this. Also make sure to run your battery down till it shuts off. This process will take you some time, but until we can wipe battery stats with CWM this is the only fix I know about.

you could flash your phone back to stock and see if it changes? or if you have a vibrant or an extra battery try using it and see if it says the same percentage or level

Battery level LIES!

My 727 (AT&T) is rooted stock rom. The battery indicator gets 'stuck' a lot of the time. It happens in both a widget and the default battery indicator in the status line.. They will both show 100% and I know full well that they CAN'T be at 100% after sitting around all afternoon off the charger. I restart the phone and immediately it drops to 42% ...
Anybody else seen an issue like this?
A lot all over. Do a search

what i suggest you do is calibrate the battery.
1 plug it in and charge it to 100%
2 turn off the phone and charge it until it says 100%
3 unplug and turn it on and leave it for 3min.
4 turn it off and plug it in and let it sit until it says 100% again
5 repeat step 3
6 unplug turn on the phone and use it until it hits 0% and turns off
7 plug in the phone and let it charge to 100%
now use as normal and after a few days your battery will read more accuratley and more importantly, will last longer. keep in mind your battery does lie to you but just use the phone and you'll start getting more out of it.
moving forward, charge whenever you can. Lithium ion batteries will last longer if they're charged often (like at 60%-40%).

Yeah, I even downloaded the utility that removes the battery life file, and creates a new one. I guess I need to try one of these procedures again.. I honestly think it is more to do with a bad application, no matter what the battery life meter should not 'hang', and if it does for more than a few minutes, then it should be able to recover by forcing a restart of the app... *sigh*...
This is a common issue with this phone. Look up "battery stuck at 100%" in Google and you'll find quite a few results. Supposedly it's an issue with certain chargers not giving out proper levels so it trips out some indicator chips in the battery and/or phone.

Just reboot your phone and use the stock charger and cable from now on.
I had this issue with the rooted kernel (can't remember which one) but after downloading "battery calibration" from the market and following the in-app instructions the problem was solved.

[Q] Roms and battery life - Unable to start phone

Hi,
I have recently tried out a few ROMs with my Nexus S to try to get better battery life. I tried CodeName Android and then figured I would try Slim ICS afterwards. I completely wiped everything and installed Slim ICS.
I have observed the following:
- Battery was ~40% when I installed Slim ICS
- I used it until the battery depleted
- Plugged phone into the wall charger
- Started the phone shortly afterwards (~25 minutes) and it says battery is 100% and then the phone randomly shut off
- Phone has been plugged into the wall charger and when I try to start it now sometimes it boots completely and then shuts off. Other times it just shuts off before it finishes booting up. The few times it does fully boot up, it says the battery is 100%
I've read through many postings about calibration but at this point I am not even able to fully turn on the phone even when its plugged into the wall.
Is this expected or is something else going on? I've never seen anything like this when I had the stock ICS. Why would erroneously report 100% but then not even let me fully turn on the phone? Thanks!

Maybe a bad battery?

Battery is fine. I ended up letting it charge a few hours and it now fully boots up and battery is almost fully charged now.
Whats strange is at times, when the battery was close to empty, when turned off and plugged into the wall, it showed the battery as being completely charged so I don't think it was charging. I had never observed this behavior with the stock ICS.

If it happens again I would suggest taking it to a sprint repair

same problem
Even I have faced the same problem whenever I reboot keeping my pfone charging,
This is very normal,
just let the battery drain completely and next time charge it till 100% it will work perfectly,
It happens with me whenever I install new rom.
basically the battery indicator shows incorrect status also battery will drain very quickly later but once you finish installation just let your phone charge for 3 hours . Problem will get solved

Also, you could try clearing the battery stats in clockwork mod recovery

Thanks. So it sounds like its more of a generic issue with ROMS in general as I never observed this before putting on a custom ROM.

[Q] Battery issues

My battery has started acting strangely for quite a while now. Essentially what happens is that when I try to charge it, it usually jumps straight from around 50% to 100%. Then, when I unplug it, it will act as if it is discharging normally for around 5%, then it'll jump down to around 45% and discharge normally. And it doesn't happen consistently, once in a while it will charge properly. It happens whether I am using a wall, car, or USB charger. I believe it started when I installed a nightly of CM 7.2 a while back, but it's still happening to me in SBF'd 608, and it could have started when I was still on CM 7.1. I downloaded a battery calibration app, and tried that several times, but it didn't help. Does anyone have any advice?
buy a $5 spare battery charger from amazon or ebay http://www.amazon.com/gp/aw/d/B006EB6LSY/ref=redir_mdp_mobile/175-4779849-7188200

battery is bad, or phone isn't charging correctly

That will fix the symptoms, but I was hoping to figure out how to actually fix it. The battery charges perfectly fine in another D2G, and it charged fine in mine on 608 last night, so it's not the battery. It looks to me like a software issue. I'm going to see if it keeps doing alright on stock, and if it does, I guess I can assume it's a Cyanogen issue. Or an issue with my install of Cyanogen, anyways.
Use another d2g to charge the battery to 100%, then put the battery into your d2g, start up the phone, plug in the charger for about 15 minutes,delete /data/battd and /data/system/batterystats.bin, power off the phone without unplug the charge, after the phone finished power off, unplug the charger.start up the phone and use it normally to it automatically power off,fully charge the battery without start up

I've been having issues too with my droid 2's battery lately, not the same exact issue you are having, but it's like when I plug it to the wall to charge, sometimes (randomly and not often) it won't recognize my battery and won't start charging and a '?' icon will appear on the battery (if the phone is turned off). I've been reading about this and people say that if you 'calibrate' your battery, the problem will be gone, so check in the Google Store for a battery calibration app and follow the steps. Good luck on it !

Issue with battery info on 44S.

Hello, how are you?
I have an issue with my OPO.
It is currently running 44S.
The issue is:
I charge it fully with the original wall charger.
Unplug and then star using the phone.
The battery remains on 100% for longer than usual.
Then it starts coming down.
When the battery gets around to 30%, the phone switches off.
I plug it and there is the message that the battery is too low and that I should charge it a bit before turning the phone on.
This then repeats itself after I charge.
My observation is that the battery remaining info is not correctly calibrated and that 30% should actually be 0%.
The battery life is normal. It just doesn't give me the correct info on battery remaining.
Anyone else have this issue?
Ideas on how to fix it?
Cheers!

how many charge cycles you been through? let it fully drain and then charge too 100% without stopping a few time. also, there are a few battery drain/calibrator apps to help you in the play store

Battery stops charging randomly

Battery stops charging before it reaches 100%. Every charge so far this has happened, which is more than annoying! Tried different chargers and cables too, no difference.
Anyone else having this problem?
First I've heard of this. You sure you don't have something draining so much that the charge can't keep up?

Nope. Battery life is excellent when charged. It just stops randomly, if I unplug the cable and plug back in it starts again. I've cleared the dalvik, see if that helps tonight when I put on charge.
