Hi guys,
I've noticed that if I plug my phone to the wall charger, when it reaches 95% it just stops charging. I can unplug it and plug it again, and I can reach 100% by repeating the process multiple times, but not in one sitting?
Is this normal? Does it happen to you? Does it get better?
Same here
(Using SuperAosp-ST 4.4)
i have that 2
I got to 98 once !

as far as i know, its an known bug
Its by design - charging the battery to only 95% level & then the following discharge. It elongates the battery life. It should never charge to level's exceeding the above.
It's not a bug.
Most batteries lifespan drop if being on high voltage too long (100%)
So usually manufacturers will try to let it state it is fully charged before it even reach 100% to extend the lifespan of the battery.
But if you really want to see it charged fully you can do a battery stats wipe in recovery after a ROM flash. It will be able to charge to 100% fully.
Hope that helps.

tried this methode, but no success.
i come from a X10 and SE build in a charging algorithm: battery charged fully, hold this value for one hour and let the battery fall till it reaches 90% and charge again.
do you mean such methode to extend battery life??
the phone from my boss (i9020) charges to 100%, my (i9023) only to 96%
96% is ok, as i said, being in high voltage often kills the battery. 96% keeps it's lifespan much longer.
Being said that, even extremely low voltage kills the battery too. So usually your phone will die before the battery reach 0%
Not this again
From the FAQ post, in this very forum, which should be read before posting a new thread:
Q: I unplugged my phone, and my battery dropped from 100% to 95% immediately, or it won't/takes along time to charge past 99%, what gives?
The answer leads to this informative article about what your battery gauge is telling you, and why 100% is probably not what you want ...

While I thank you for your reply and linking to that article, that is a related issue but not exactly the same. The usual behaviour is for the battery to indicate a 100% charge and then drop to a lower level, as you bolded in your post. The behaviour I'm talking about is it never going over 95%.
Not a big difference, but enough to notice the change and ask about it. Don't you think?
I myself own a GT-I9020T & have never seen the charge levels exceed beyond 95%.
You are right, your description is subtly different than the post in the FAQ. I have to admit laziness in assuming that they would be one and the same 'problem' ... apologies if they're not.
Well, you did give useful info even though you thought it was an old, tired question. I can't see a reason to give apologies there
Turn the tethering on while charging; it'll charge the battery up to 100%
I think my Vibrant had the same issue / feature. It's probably a Samsung feature and not a bug.
Sent from my Nexus S using XDA Premium App
Mine hits 100pct sometimes but will always stop charging until it drops below 90. A good feature to save the battery. Makes 0 sense for it to be charging every time it drops 1pct for hours at night while on the charger.
I'm wondering if people seeing a difference in the overall charge cap is a matter of rom? I've been using cm for practically ever but I know some people are on stock. I'm sure it's possible something is modded in there to make sure it hits 100 before it stops.
Just a thought.
On nexus s with stock rom I was able to charge to 100%

maybe thats the problem, because the phone of my friend also charges to 100% (completly stock) mine only to 96% (NSCollab)
So I bought my phone just after the first day of release. While battery life isn't bad its still pretty questionable. But for now my main issue is the battery level. When charging my phone, the battery level never reaches 100%, it usually sticks around 97%. When I go to check in settings, the battery reads fully charged but the percentage says differently. I just wanted to know if this is an issue that anyone else and if a battery calibration will help fix this.
This had been addressed many times if you charge a battery to 100%.... they explode after a while. 97 is normal and good don't think to much about it your phone is fully charged

It's a samsung/gingerbread feature , to prevent causing any damage to the batteries
Ok cool. While on topic of batteries, what kind d of usage are you guys getting out of yours? I've noticed that I need to turn off internet throughout the day without getting too low when away from a charger. I know around school I have bad signal and there's not much I can do for that, buried there any other advice?
I can't seem to figure out whats wrong with my phone. I have a draining issue with my battery and i don't know if my battery indicator is not accurate. I used odin and went back to stock on a full indicated battery. Then I flashed VB and adrenaline shots 1.4-1 and camera tweak and scrolling mod and booted the phone and let set for 10 minutes before I reloaded all my apps. My battery was indicating it was at 100% ok so i unplugged the battery and wham it dropped to 79% plugged it back in and it started charged from where it left off at 79%. After a few min and the phone goes to sleep mode and indicates 100% i unplug the phone and it charged from where it left off at 79%. So i kept unplugging it and plugging it back in every few minutes till i got to 100%. So sounds ok now but i had to reboot my system and wham again down to 79% and even with the uv settings my battery drains fast. I tried calibrating the battery and also charged it with the phone being off and no results. All I want is a full charge as I work long shifts lol. thanks and i hope this is understandable the way i tried to describe it.
Also Thanks to the devs on here who dedicate their time to making this device do what it was meant to do..
Try letting the phone die completely. After about ten minutes power it back on then let it die completely again. Leave it off for an hour then plug into wall charger. Let it charge to 100% while off. After it hits 100% unplug it and leave it sit for an hour while off. Then turn it on and use normally.

Not to contradict hechoen - but take note that Samsung recommends against completely discharging your battery in the manual for the phone.
+1 (edit: on previous calibration routing)
also you may try to "jump start" MAX17042 (fuel gauge) chip... when your phone at 100% on a charger (verify this by looking at battery voltage - OS Monitor / Misc tab. or other similar apps) - voltage should be around 4.15 - 4.2V. When you disconnect charger - what would be the voltage then? If around 4.0V then may be your battery is going south.
To "jump start" FG - turn off the phone, pull battery out and wait for 5 - 10 min. - just to be sure internal circuits got completely discharged.
When you install battery, FG chip will use "average" model for new lipo... see if it makes difference.
Yeah I've heard that this kind of batteries last longer if charged continuously (short and often charges) instead of full charges after letting it die. Something about battery cycles or some.
I'd recommend fully charging and battery calibration from market. Also, reflash rom but not tweaks yet, and see how it behaves. Then install tweaks/mods and see if the battery continues to decrease rapidly. If it does, get an app for battery info, check its health.. Your battery might be dying for good.

Google has also debunked the battery calibration myth. There is a thread about it in the General Section with a link to the article.
To add to the recommendations...
Check how often your phone is set to sync. Big battery drainer. Auto starting apps. And display brightness.
if all fails you could try to reflash and see if that fixes it

Wait, I didn't say battery calibration is going to make your battery last longer. It doesn't do that.
But it's a fact that after installing a rom a battery calibration is needed. Normally, developers code their install scripts to perform a battery calibration when installing the rom, so this is not needed afterwards, I still do it anyways when charging the first time to 100%.
I for one had the issue for the first time when installing a rom (don't remember which one) and after rebooting or shutting down the phone, the battery would go from >90% to <20% for no reason at all. Someone here at XDA suggested battery calibration app (or, manually at CWM/advanced, clear battery stats) and the issue was gone. Maybe the rom is misreading battery data and that could cause this kind of issues... which a battery calibration would fix it.
Just saying.. if there's an option for it in CWM, then chances are it is needed for some reason!

Indeed. It's on our wiki, too, under the batterystats.bin Buzz Word entry.
So i think I needed to do a factory reset. I re flashed vahnilla black and then did a factory reset in the rom. Before I re flashed the rom I
had 60% as soon I restarted the phone on the freshly flashed rom it dropped to 1% then I did a factory restart within the rom and when I rebooted the battery indicated 20% and I am in 16% charge now, only went down 4% within the last 6 hours. So I will run it till it dies tonight and charge it with the phone off to see the results tomorrow.
Thanks Raver for the help in this matter. Will keep everyone posted on the end results.

No contradiction at all. You shouldn't fully discharge all the time. But once in a while it's actually good for the battery. Especially lithium ion. Take a look at this. For those of you who don't like to read that much just skip to the bottom.

I fully charged my battery last night while it being off and let it sit for a hour before turning it on. Well great seemed to now indicate it's fully charged after a hour I threw on adrenaline shots 14-1 with camera and scrolling mod. Let it air for 30min went into recoveryand fix perms. When I rebooted the phone the battery dropped again from 80 to 60 and then went back up to 75. Then I rebooted again it dropped to 25% and then I rebooted again and now it indicates 59% I believe this battery is heading south. What do you guys think?

How old is the battery. If it is a quality battery it should take between 500 and 900 recharges. Do you own a volt meter?
Also calibrating your battery should be done occasionally. Not to somehow make your battery last longer, but to clear out the old data and use new data to show your batteries usage. Just like resetting the computer in your car that shows average MPG. Fresh input will give you a better idea of what your car is getting today and same goes for your battery stats.

I have calibrated the battery. Everything seems to of been working fine until I added adrenaline shots. Once I rebooted after installing adrenaline shots my battery started acting up again. I pulled the battery out for 10 min and popped back in and now I'm indicating 56% after 4 hours of heavy use with wifi on. :/

Is this a factory battery? Or a aftermarket ebay/amazon battery?
Im sure people will disagree but some of those aftermarket batteries are not the greatest quality.
Do you live in a town that had a battery store, like the interstate battery shop or something of the likes? Most of those places can do a brief diagnostic of the battery and tell you if it is bad. Or if you have a volt meter fully charge it and test it that way.
It really sounds like the battery is being stupid. There should not be any reason installing A.S. could cause a instant battery drain. If that were the case your phone would be so hot you could not hold it. Because draining that much juice in that little of time would indicate you have a short or something of that nature.
Hello. This issue has been going on for a while now. But when I take my phone off the charger when its not fully charged. The battery percentage keeps going up. For example if I unplug it at 78%, the percentage will gradually go up to like 86-88%. Can anyone give me a hint as to why its doing this? Thanks!

Battery stats are wonked out.
Do you have Clockwworkmod recovery installed? Or is this a pure stock unrooted?
EDIT: Mr. Jacob, what are you tense about? LOL ! Just kidding....
Try using an app called battery calibration (can be found in the app market) when the phone is fully charged. This will reset all the battery stat logs and set your 100% to a true 100%
I have clockwork installed. I'm running SkyICS rom. And I have already tried battery calibration.

Battery calibration does nothing. Normally I wouldn't recommend that u COMPLETELY drain the skyrocket battery as its lithium based and can cause dead cells, yours needs calibrating, and wiping battery stats or using a battery calibration app won't help (both of these are myths by the way, Google if). Use phone until its completely dead, and won't turn on at all, only vibrate with a black screen. Then charge phone for a continuous 8 hours uninterrupted, that should fix it

As a first try, charge to 100%. Then go into CWM recovery and wipe battery stats. It should be good to go....On ICS, thsi seems to fix it for me.
IF you then stilll have weird battery problems a proper recallibration will be in order.
I had to just wipe battery stats when charged to 100%. DON'T just wait for 100%. Alow the phone to get to fully charged.....if you have "Full Charge" notification on your ROM wait for that.

Half of this is right chappatti
charging to 100% and letting it sit for at least an hour even after full charge notification is the best way. Wiping battery stats in cwm won't actually do anything though, thats a myth.
Actually, for lithium ion batteries, it is not recommended to let them discharge to zero. It's better to run it down to 10% or so (i usually do about 5%). and then charge it completely. Rinse and repeat over a few days, and there should be a difference.

What a revelation !! It's like realising my religion is all wrong !
BUT, BUT, BUT : reading the whole battery stats discussion, it i also clear that the business of charging for an hour after 100% is also not worthwhile, but is just a customer gimmick to make people feel thier batteries are topped off. This was started by HTC and the consensus is that is also does not help.
The simple solution is to let the battery go through 2-3 charge-discharge cycles.

A good read. Very useful, thanks !
I had this same issue with my Exynos G2, my problem was flashing different roms or putting a theme on. My fix came not by wiping battery stats but only doing flashes at 100% and plugged in. I never noticed it on my SR though. I'm not saying don't try what the others say, just giving you more options.
I don't know if i'm being paranoid or what about my battery %, but whenever my phone reaches around close to 30% it goes down instantly to 19% in like a minute all the time.. Not sure if my phone isn't used to my rom yet but it did that when i flashed sc7 and sc6 (gb).. Has anyone experienced this issue before, or my battery needs to be replaced?

Wipe battery stats?
If that even works on this device, I know it was just placebo on Samsung devices.
Yes you wipe battery stats through custom recovery. But you need to calibrate your battery as well. Each time you switch ROMs, be sure to do this. I was having same issue except mine would hit 30% then instantly drop to 5%. Calibrating the battery and a few setcpu tweaks fixed my insane drainage.

Hmmm I just saw my battery went from 30 down to 20 again.. maybe my battery isn't calibrated enough? i followed the steps in charging it phone off and then calibrating the battery with the app..

Which App? All you need to do is go into CWM and wipe battery stats. Anything else you use will not work right on this phone. After that it needs to be 3 "FULL" battery cycles (fully charged to fully dead, or to 5-10% at least, then fully charged again).

Literally from one second to the next it goes down 10% or so. Don't have another battery but my wife has the same thing. Does it after a factory reset as well as after installing 60 apps. Before and after battery calibration. None of it makes any difference.
The only other thing I can think of is that a certain battery percentage kicks in a certain lower clock speed and that that process kicks 10% of the battery. Not likely in my mind, but possible.

After about 3 weeks after making this thread I still get the same thing.. From 30% down to 20% in seconds sometimes it happens at around 40% which is utterly absurd
I have also noticed this problem sometimes, when I do run it that low. My jump is from around 30 to 20 percent. I did wipe stats a couple of days ago after I flashed swiftytrix from ICS leak 1. However, after wipe stats, I didn't discharge to completely dead, but close to it. Does that matter?
