I got a second battery off ebay for emergency situations. It's advertised as OEM. While the phone is plugged in it charges up to 88% then starts bleeding charge. Unplug and replug makes it charge again. Bad battery right?

I got a new battery from eBay just the other day too, and the first time I used it, it didn't seem to charge properly at all. I left it in the phone and drained it down to 1%, then charged it again. This charge seemed to take forever, but after it was at 100%, all seemed fine. Now it charges at normal speed again, and doesn't seem to drain any faster than my stock battery. Hopefully this works for you too

ok, over the last week or so ive had this issue, gradually getting worse...
my battery will charge to around 40-45% and then charging will slow right down.
two hours later, it will be on around 50% if im lucky, and about 3 more further hours before i hit 60% (this is some of the time, other times, it just remains on its current charge%)
if i leave it overnight for about 10hours or so, highest it goes to now is about 73%, but this is rare, usually 45-50%ish.
ive tested with htc ac wall charger, htc usb, blackberry charger, car charger and a random microusb wallcharger. all have same issue.
when tested with two friends desire hd's on different days, my battery charged perfectly, and at the normal gradient speed over the % range. and my phone reads it correctly at the 100%-98% when back in my phone after change back.
i thought it was down to my phone, just dont know if its rom or hardware. shud i factory restore, or claim on insurance?
i have another issue here...http://forum.xda-developers.com/showthread.php?p=18480603&posted=1#post18480603
which also applies to the question of restore or insurance...
thanks
What Rom are you using, i am using runny 2.2 only 62% charge in 6 hours
9 hours later on battery only upto 68% i have amazing battery life now
i'm using runny 2.2.....left it on charge for 2 hours with phone on, but wifi and everything off and it had only gone up 2% ! !
Turned phone off and plugged in charger, 30 mins later, only went up 1% ! !
72% charge at this point.
So took it off charge, put it in my pocket, went upstairs to bed, turned it on to set alarm and it said 100% on battery....weird!!

Lol this is an issue with calibration. The battery is charging but the software doesnt report it.
You have to charge the phone for as long as possible so you know it is on 100% whether the software says it or not, go into CWM, wipe the battery stats and then let the battery drain fully until it shuts down by itself. Then plug it in and leave it until you know for certain it is at 100%. If the green light comes on leave it for an additional half an hour. Then it will be fixed.
ive only recently got this handset, as last one was replaced on insurance a month or so ago, and its runuing on stock rom with latest updates....?
Is it me or does our phones charge super fast?
I drained it to 0% (let the phone die by itself while watching youtube)
Then I plugged it in at 8:05AM this morning.
At 9:05AM it was at 45%.
Pretty impressive.
(Once charged to 100%, should I wipe the battery stats and drain down to 0% again? This is how you would calibrate it correct?)

If you are getting incorrect stats then yes, clear the battery stats. The best way to calibrate is to drain, refill & repeat. Along the way when the battery is 100%, turn it off and charge it till it says its full again. Do this a few times when it's unplugged and you will see better life.
Speaking of fast charge.
I had 17% left at around 12:30pm today. Plugged it in while I went to lunch. Now at 2:50pm, just got notified that it's fully charged. Not bad at all.
Also, I had drained my battery when I received my phone.
How is that even possible!!!!!!!!!
It takes me 3.5 hours to charge it full!!!!!
Damn!!
I have two lines and this is my second SGSII aside to the one I already have...
I got this phone just yesterday and last night was my first full drain....today was my first full charge.
Shouldn't I go into recovery and wipe the batt stats?

I noticed today that the output from the charger for the SGS2 is 5V 1A and all other usb chargers ive gotten recently have an output thats closer to an actual usb port (4.5-5V 500mA) so that might have something to do with it.
My test pool on this hypothesis is quite small though so id be curious if anyone else can corroborate
I notice my battery charges much faster on an official samsung charger. Anything below 1V charges super slow. I want to try a rapid 2V charger but worried it may ruin my battery.. but on the other hand, AFAIK, some samsung car chargers charge @ 2v. They're called "rapid chargers" This is one of those times where you think AH any generic charger would do. I used to be in that camp. But I really found that the Samsung chargers are quickest. Also, they seem less likely to damage the micro usb port due to repeated use due to the fact that the Samsung cables tend to be thin and light weight as opposed to thick and bulky like some eBay cables. The thick and bulky ones feel like they'll give you enough leverage/weight if grabbed the wrong way and tear your micro usb port right off.
In the end, I love the Samsung chargers.
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.
So I've been having issues with battery life and my charging.
When I woke up this morning my phone was at 1%. I went ahead and played with it till it died. I kept it turned off and let it charge for about 2.5 hours or so. I would think that it would be close to fully charge. The battery charging icon when phone was off made it seem that way, but when I turn my phone on it's only at 40%. I turn it back off and let it charge for another 1.5hr while i'm at the gym. Come home to find that it's only charged up to 46% since then.
This is a brand new, official samsung battery. Came with the Samsung spare battery charger. Similar things have happened with a 2nd spare battery i've bought. None of these issues happened when I was using my original battery though.
Do you think it's the phone or the battery itself? I'm leaning towards phone
Phone was at 98% battery. Did a reboot as I do every morning, and when it started up again it showed 91% battery. I know reboots don't take 7% battery, so what gives?
My Pixel 2 XL has been having some battery reporting issues, I noticed that when I took my phone off the charger it would lose 15% very quickly then stabilize. Rebooting would also cause a drop in indicated battery %. That's my guess. Investigating to see if it can be fixed by doing a full charge/discharge cycle.

I've also been seeing this issue! I will also be letting it do a full cycle today to see if it helps since it only started a few days ago.
My battery seems to be okay but my charge port when I place the cable in it doesn't feel like it fits snugly it almost has a slight wobble to it. Have you guys been noticing that as well?
I've actually been experiencing this as well for a week, I called up Verizon and they shipped me a new phone. So far no charge issue anymore on this one.
I have experienced this too
Tested this again this morning. Had the phone charging overnight.
Unplugged it, it showed 100% battery.
Immediately rebooted, and it dropped to 96%.
With a lot of phones, battery stats reset on reboot. Also- the percentage isn't a perfect science. Just let the phone do its thing. Run the battery down and recharge it. No need to reboot the thing every day.
The battery has been great for me. I use my phone extensively throughout the day, maybe 3-5 hours on time, I always make a day of use without needing to plug in. I had a light use day yesterday, and had 30% left @ 11pm, after pulling off charge the night before @ 11:30pm.
Pleased to announce that (in my case at least) doing a full cycle reset the fuel gauge and it is now working properly. I've never seen a device come with a miscalibrated fuel gauge from the factory, so that was odd. I usually keep my li-ion powered devices between 80% and 30% SoC(state of charge) to reduce cell degradation so we'll see if the fuel gauge becomes uncalibrated over time (which would be somewhat unusual) or if this was simply a software fluke.
Yea I have noticed that in my case, my phone says 100% on the charger so I will restart the phone while still plugged up and once it's booted back up it says 98% so it lost 2% while hooked up to the charger lol. Doesn't seem to affect the battery life. I'm still able to get 5 hrs of screen on time but I will try to kill it completely and charge fully today and see if it fixes it.
This morning I didn't do the restart and didn't use the phone or even turn my screen on and within fifteen minutes I turned it on to 98 % remaining.
