My phone doesn't charges above 70+,if i remove the battery and reinsert it it shows 92% after that it charges normally till 100%,again the same thing is continued in next session of charging. ..I tried calibrating the battery by removing the battery and hold the power on button for 60+ seconds and also tried the battery calibrating app..no use at ol...one thing is, if a use the mobile continuously it charges very slowly after 70+,if its not used again it stops charging but indigates as charging,till 70% charging is smooth and fast...pls help me to troubleshoot this thing plzzzz... :crying:
sounds like you might need a new battery
Yes, you need a new one.
Most batteries from more than a year ago starting to have this problem after updating to 6.0.1
The update stress the battery too much and if your battery is more than a year old, will likely be damaged after that stress.
Yes, samsung batteries are less than cr*p.

Man, I hate starting new threads! I did a simple search and couldn't find this problem anywhere else, so here goes:
Earlier in 2009 I bought an extended 2400mAh battery for my Kaiser (8925). Everything is working just fine, except that I noticed that the phone doesn't seem to notice that the battery life is much better for this new battery.
What I mean is: after a few hours of usage, the battery level drops at a normal rate.
Once the phone tells me the battery is almost dead (and sometimes the phone will shut off if I ignore this), I can shut down the phone, remove the battery, wait a few seconds and then replace it and boot back up the phone.
At this point, the phone will usually tell me that the battery is at 33% to 36% charged. Notice that I did not charge the battery, I just removed it and put it back in.
When I first got the battery, I cycled it completely three times in the phone, removing it twice and replacing it to ensure that the battery was completely drained before charging it to 100%. (Yes, I know that is only recommended for metal-hydrates, but I feel better doing that anyway).
On the top-end, it usually takes about two hours to charge the phone from 30% to 99% via a standard USB2.0 connector.
However, the phone will report that the battery is not fully charged for nearly an hour after reaching 99%.
I know what you are probably thinking; Why is this guy complaining about his battery performing better than his phone reports?
Well, it IS kind of annoying. I would like the phone to properly report the remaining percentage for my own benefit. I really hate having to guess at how much time I have left before I need to drop it off at a computer or wall outlet while I find something else to play with for three or four hours.
So... Does anyone know how I can convince my phone that the battery is pretty awesome and to start reporting the actual battery life?
I just got some new batteries for my i-9000. I am wondering, I have always heard LIthium batteries do not like to be fully discharged. I want to perform a calibration on the new battery, but all the battery calibration apps say
1.Fully charge the battery
2.Press calibrate battery button.
3.Run the phone fully flat until the battery dies.
4.Fully charge the battery to 100% uninterrupted.
Now, step 3, going all the way until the phone dies, is that a good thing to do or a bad thing to a new battery?
Letting your cellphone's battery drain until the phone dies is a normal thing that won't damage your battery, because the battery won't really go to 0% charge.
Cellphones always shutdown it-self when the battery levels get too low (like 3%), to avoid the damage it would do in the Li-ion battery if it would go to 0%. So you have nothing to worry about.
yeah mine shuts down around 2-3% percent for that reason. You'll be fine.
thanks.
.
just doing it once when you get a new phone or after noticing horrible battery life on a newly flashed ROM can work wonders
other than those times, I only let my phone get to 20-40% before I plug it back in
I Use BOS Gingersense Port From Kingdom, My battery is good and i didnt do that whole discharging,recharging crap.
calibration works for me...
Calibration even worked for me too, on my Galaxy 3. Previously i was getting backup of only 1 day, but after calibration i get around 1.5 days. I know its not much improvement, but still its worth.
And you don't need calibrate frequently. Just once in two weeks is fine. And I've heard that deep discharge once a while is infact good for the battery. Correct me if I'm wrong.
waiting for phone to completely die right now. One question though can I turn on phone while charging or should I just leave it off after dieing?
I called Sammy, they told me letting the phone turn off by itself because the battery can't power it is bad for the battery in the long run, they said you can't really see the bad effect that time, they told me, we have learned on are testing that when you see the low battery message pop up that is where you need to charge the phone, that warning is where the calibration starts, now draining it to the point that the phone turn itself off is bad for the battery. Do you believe that?

Only if you leave the cell empty.
It's best to recharge a cell as soon as possible if you have discharged it.
Discharge/charge cycles should be kept to a minimum, ie when you first get the battery, when you are sure you need to recalibrate, and when you've got no choice.
Top up charges are best for lithium batteries.
The charging circuitry in the phone should protect the battery from over discharge. It also protects the phone from overcharging. However, just like a spring, it's the constant charge/discharge that damages a battery. I would not run it down every day but it should not damage the battery, only cause it to wear out faster.
Source: I'm an electrical engineer.
Try to avoid frequent full discharges. Occasional full discharges are okay.
Lots of uncertainty here, lol.
A new Li-Ion cell will output ~4.2V when fully charged and ~3V when it is totally discharged. Every single smartphone I've owned would shut down before the cell dropped below 3.5V. Draining your phone's battery until it dies will not hurt the battery or your phone. No worries about batteries catching fire.
Repeated or frequent full discharges will wear your battery out much faster, though.
Hey XDA, I just purchased a new AT&T SGS3 and I'm having some issues with the battery on the phone.
When I charge the phone overnight it charges to 100% then when I unplug it, the battery drops tremendously in about 5 seconds down to anywhere from 50%-75%. I tried manually recalibrating the battery by charging it 8+ hours, removing the battery, charging again while off, charging it again while on, then restarting. That seemed to work for one charge and the battery acted the way that it would have on my Nexus S.
However charging it again after a full battery drain, the same thing happened.
Also when the phone is low on battery, it displays the normal battery messages, but then the screen stays on, draining the battery faster.
Solutions? I want the root the phone, but only after I have these issues sorted out. (I'm still under warranty right now)

Did you try a reset of the phone through the settings ? After that try charging to 100% then drain completely and then recharging without break then use the phone mormally and try to recharge only when it hits 10% remaining for the next 2 or 3 charge cycles and see if that helps

Looks like a bad device. I would send it in if i were you.
I had this problem: my phone (Arc S) died saying it had low battery (even though I had checked it just a minute ago with 25% still left).
I tried to charge it but nothing happened for 30 minutes.
I knew that taking out the battery and reinserting it after a while usually fixes this but this time it did't help. The phone could not be started and it wouldn't charge either.
Solution: Borrow a friends battery (if he/she has the same phone ) or buy a cheap one of the Internet (there are batteries for about 4 dollars).
Put the new battery in your phone and start it. Turn it off and quickly put the "dead" battery in again and insert the charging cable and it will charge and function as before!
My humble guess is that the charged battery leaves some juice in the phones circuits that stays there for a while and can help a "dead battery" charge again.
I know your problem : http://forum.xda-developers.com/showthread.php?t=1312398
No that's a workaround/patch to 0% battery issue caused by downgrading firmware from 2.3.4 to 2.3.2.
I've never downgraded! This problem is rather from the phones difficulties sensing the batteries power level correctly.
Thanks anyway!
Hey guys, I've had my phone for 4 or so months now and I always charge it while my phone is off and never had any charging/battery issues until today, I decided to charge my phone while it's on and it charged up to 25% and I restarted my phone without removing it from the charger and after it booted back it it's showing 50%, I restarted a few times, tried a cold boot, it's still 50%.
Is this a known issue with this phone? does anyone know what's causing this? I've never had this happen before.
EDIT: After this happened I ran my battery to 0% so I can attempt a battery calibration and when I poped it on the charger it showed my battery was actually 0% and showed a yellow hazard triangle thing (normally it only drops to 1% and there has never been a yellow triangle before)
Sometimes the Android system can incorrectly report a battery charged. I have had it happen to me on my Nexus by about 10%, but have not had it happen to me on my G3. I would not worry about it too much if it only happened to you once. If in continues you to jump around in battery percentage, then I would suggest getting a replacement battery. Keep in mind to try not to leave it charging for very long after reaching 100%, from my experience it can effect a battery's ability to hold a charge if that is done repeatedly. Which means do not leave it charging overnight while you are sleeping. Also I would not suggest running it until 0%, I would imagine a sudden shut down of the Android Operating system is not a healthy thing for it either. Just like it is not good to go up to a computer and just pull the power cord.

Thanks for the input.
I never leave my phone on the charger while I sleep since it only drops 1% while I sleep. My phone actually only goes on the charger like 3 times a month
I know it's not good to fully drain the battery very much, I was just draining it to attempt a battery calibration in the os. And when I do this my phone usually only drops to 1% then dies, but all of a sudden it dropped to 0% this time and showed a big yellow triangle with a big exclamation mark in it
Anyways I reflashed my rom in hopes I can flush the problem out. In 4 months of owning this phone I've never seen this warning before.
This is almost exactly what happened with my old phone (Samsung Captivate Glide). If this continues to happen, it is one of the first signs of the battery failing. But if this is a one time thing, I wouldn't worry about it.
In my case, the battery was going bad. It started going from any % battery, down to 0 instantly, forcing a shutdown. After rebooting, It would show a decent charge (~60% most of the time), but would do the same thing within 5 minutes. At first it only acted up like this once a month, but it became more and more frequent that it happened every day, after using the phone for only 15 minutes. The only fix is to get a replacement battery.

tyvm, This is extremely helpful info to keep in mind. Now that you mention it I have seen the battery kinda swollen up a couple times when it got hot, only ever so slightly but I did notice it.
If my issue persists i'll defnitly try a new battery, thanks for the tip
