Is my battery dead - Galaxy S II Q&A, Help & Troubleshooting

SO the original battery is about 1.5 years old. My phone started dying at strange times and refusing to power on, or dropping from 80% to 10% if it powered on again.
Right now there seems to be a charge in the battery but I can't get the phone to power on at all.
The spare battery seems to work so it is some battery issue, but is it dead or can I revive it or another 6 months?

Everything you've said points to a battery on the way out, and the length of time you've had it does as well. Constantly discharging/charging a battery for 18 mths, gradually reduces the life/reliability of the battery.
Buy a new one/use your spare.

So I managed to get it working again. I tricked it by connecting a extra small battery at the same time. After powering on and disconnecting it three phone seemed to recognize the that there was a battery again 2% charged. I charged the battery with phone off. When I powered in the phone said 12% and I charged it again powered on. It's been holding up for 2 hours of use at 86%. I guess I will just have tip wait and see.

Could be battery calibration problems... Try to calibrate it. And a lithium ion battery life is expected to be 1-2 years.

Charge questions.

H, I just got the x10a. I have some questions about the process of charging the phone.
With my last 2 phones, an k850 and a xperia x1a i learned to charge the phone every night. I arrived at home, plugged the phones to their chargers , sleep. Wake up, went to work at 7, battery was at 100% every morning.
Now with the x10a, i arrive at home, battery is almost at 40% aprox, plug the phone to the charger, and go to sleep, wake up at the same time and battery is always at 60~70%, with the cable and back of phone running hot. Yesterday went to see the phone status at 11pm, battery was at 90%, went to sleep, wake up at 4am checked the phone and battery was at 52%, so instead of charging, was discharging, is this normal behavior? I removed the battery and put it on again and the charge jumped to 85%.
All of this is normal?

Kind of if it's new, cycle the battery a few times and it should sort itself out.
Yeah the same thing happens to me. I checked juice plotter and at 2:30 am, I'm fully charged then at 5:00 am, I'm at 70 percent. The it repeats the cycle.

That is very odd.. has someone timed how long it takes for the battery to get to 100% Just today I got the please charge now message.. it took 2 hours give or take to get to 100% it maybe you need to cycle the battery. I am using my blackberry 9700 battery charger ( OEM one was left in my hotel room ) The blackberry is output 5VDC and 700mA.
I've noticed that charging the phone using a USB port takes a lot more time that when using an AC/DC adaptor. The USB ports on my PC give out 100 milliamps while the AC/DC adaptor that came with the phone gives out 700 milliamps. Are you charging using a PC USB port or an AC/DC adaptor?

I've had this happen a few times I plug the phone in at night & when I wake up it's still charging and warm. I now shut my phone off before plugging in the charger & have not had the problem. My guess is some process is running in the background preventing it from properly charging.
ya just cycle the battery few times and it should be okay. it should be noted that the x10 will charge to 100% and stop charging until the battery drops down to 90% (at least for me)
Phone off worked!
Had a same weird issue after 5 months of usage. First 5 months were fine (needed to charge once every 24 hours). Have noticed in past 2-3 days that when I leave it for chanrging overnight, it does not go to 100%. Sometimes it would go upto 76%, other time 86 and so on. Cannot understand this. Have not installed anything in last 2-3 days either. Do not know the root cause but solution suggested by Phoneguy above worked. That is, I put netwrok setting OFF and then switch my phone OFF. Then I plugin phone to charger and start charging. This way it is getting charged to 100%. Hopefully this workaround will last for another year, at least

Mine does the same thing. I checked with battery graph. It charged to 100% and then it'd stop and drop to 90% and charged back to 100%, in repeated cycles. Is this just a X10 thing? I want to have 100% before leaving the house!

This is normal and for Security. When you leave the Phone charging when it has 100 it stops Charging until 90 or something then charge again becouse if it wouldnt do it your Battery will run too hot and could make real damage.

The phone actively discharges the battery when plugged in. I've tried the above suggestions and they worked, but only found small success as the battery wouldn't charge past 40%. Now my phone will not boot and the battery is completely drained.
I called SE North America last night and they told me that I broke the battery. I called BS and they then told me that they'll send me a free new battery as a courtesy despite it not being covered in the warranty. Overall, a pretty good experience, but the key point the rep said was to not trickle charge the battery.
I do have a sneaking suspision that it's not the battery because it's only 5 months old, but good because they didn't say anything about the phone not being officially released in the US and not being supported by a warranty.
I hope this post doesn't get deleted as well...lolz.
here it is my graph for the last day, plugged the charger aroung 4pm batt was at 13%, in the office and around 8pm from home, if you see, from 8:44pm to 9:41pm the batt was at 100% an then it goes down and reach 60% at 3am, so it was discharging, and then it tried to charge to reach 100% but couldnt. at 6:30am i woke up and bat was at 78%. so, how can i get it to keep the charge, i dont mind going form 90 to 100 but not going from 100 to 60 and to 100.
anybody can help?

Battery Calibration

Has anyone run across this? Lately when using Battery Calibration app, as soon as I unplug from charger I drop from 100 to 96...( happens frequently now) is this just a sign my battery is getting weak?
Sent from my SCH-I500 using XDA App
Nope - that's actually the correct behavior for a well-calibrated and healthy battery. When you charge your phone disconnects the current when the battery is full, and for the next half hour or so it reads 100% but the battery is slowly discharging. This protocol preserves battery longevity. After a while it will top the battery off again. Long story short, 96% charge shortly after unplugging is perfectly normal.

thats funny, my device stays at 100 percent after I unplug it from the charger, then discharges normally. It never drops to 96%, sounds more like a kernel issue to me.

When still running Froyo my Fascinate always displayed 96%-100% upon disconnection after full charge, even if left overnight. After update to GB, the longer it remains on charger after reaching 100%, the lower it drops after disconnecting. Sometimes it's dropped from 100% to 76% as soon as charger is unplugged, if left on charger for too long.
I was informed on another forum that there's trouble with the trickle charge function on GB and it's likely not to be corrected.
Just thought I'd pass that on, for what it's worth.
the battery does that on purpose so it doesn't overcharge and decrease battery life.
in other news, google android people have said more than once that battery calibration does nothing, wiping battery stats will not help anything at all.

I normally Charge it while Battery Calibration is running, then when it hits 100%, I power off the phone and let it finish charging with the power off then onces its "Truly" fully charged I turn the phone back on get into Battery Calibration then press the calibrate button
What's the general consensus on this i.e. Google engineer basically debunking the necessity or benefits of calibrating one's battery?

Charging phone does not work.

My phone dropped to 7% battery. I let it charge for an hour with airplane mode on and it was at 4% battery. The orange light was on the whole time meaning it was charging. I then turned it off, took the battery out and it went to 13% battery. Soon it went back to 4%. I let it charge again for 2 hours this time and it hadn't moved at all and was still at 4%. I then swapped the stock battery for one from China. It started with 60% battery and after a half hour of charging it went to 54%. Why does my battery drain while it charges? I don't even use it when it's charging so I have no idea why it's draining. I'm running stock ics but it's rooted with 4ext. Any ideas?
Thanks.

Charge with AC not through an USB plugged to your computer. Your phone is using more battery than the USB port can provide. If you plug it in through the normal AC charger, it should be fine, as it gives out 1.0A, while USB ports typically give out anywhere between 200 to 500mA (at its absolute maximum).
I am using the ac. That message even appears when I use the ac.
Have you tried turning it of and charging?
Sent from my HTC_Amaze_4G using xda app-developers app
I have tried that and it only turns on to what the battery was at before. As I typed this I went from 54% to 21% in about 10 minutes. This is really starting to piss me off. My phone cannot hold a charge. My motorola from 8 years ago could at least hold a charge. This is ridiculous. Thanks so far for the help.
Are you using the factory Amaze Cord to charge your phone?
My factory amaze cord stopped charging via ac. I had it plugged into the wall and it would say usb charging so I'm using a different kind of cord. I've never had a problem using my sisters blackberry cord plugged into the usb converter to ac.
Maybe....just maybe...your devices charging port is defected...
I have some charger from China that goes from the wall straight to my phone without using that charging port and it doesn't charge it either.
China should only be used for one thing...Chinese People
I tried another one of my batteries that had a 60% charge. Within 10 minutes the battery was dead. I have it charging and the orange led is flashing. I waited 20 minutes and tried turning it on. After several presses of the power button it finally turns on. As soon as it gets to the home screen the low battery sound beeps and it shuts down. Seriously what am I supposed to do? This is getting ridiculous.
Thanks.
Have you looked into doing a warranty exchange...

powered by the fastest Faux in the woods!
I have not. This has only happened 3 times or so since I got it a week or so after launch. I didn't suspect it to be a hardware problem. I think the person who suggested the bad power port was correct because my Chinese charger charged it full perfectly and it's been good. It just has to be held at a certain angle to charge. I'm going to go to Telus and try and get a new power port and see, maybe I could get an exchange. I have it rooted though, so would I have to unroot it get the exchange?
Thanks.
Step one, dim the phones lighting.
Then check to see if there's an app keeping the phone awake causing it to drain battery while charging,
If its not an app keeping it awake then you my friend are one of the unlucky owners of this picky phone...

Extreme battery drain, phone shuts off, then shows 80%, then 50% upon reboot.

My DX2 suddenly sucks for battery life. This morning I took it off ther charger at 100% and used it for 20 minutes looking at twitter. I got the 15% remaining message and 2 minutes later I get the 5% message and it immediately shuts down. I go to plug it in and the larger battery graphic comes up (the one it shows when you are charging it while it's off). And it says 80%. So I unplug it and turn it back on. Once it went through it's boot up and aquired signal and all that, my battery widget shows 50%. I plugged the charger back in and in about 10 minutes, it said 60%.
A couple days ago, I left the house with 90% and turned on GPS and navigation. I got 8 miles from my house and it shut down due to dead battery.
Is the battery going bad or is the phone going bad that it can't read the battery?
Whenever I check the battery usage, it either shows DISPLAY or IDLE as the number one battery user.
What are you running for a ROM?

Sounds like a battery issue or defect in the phone somewhere. Or, it could be a very old custom rom but you haven't answered that yet so not sure.

No ROM. Bone stock
Sounds like a dead battery to me. If you know anyone with another X2 or a Droid X (same exact battery) try swapping. If you continue to face the issue it is a defective phone. It someone else's battery seems fine it's a defective battery.

Battery drain (Important help quick please)

I was in England last week and I noticed on the last 2 days my battery not only drained itself much faster than usual, but it also recharged slower. When I got back home, I noticed if my phone was plugged in, and I used it, it still lost battery! I use the original charger, one thing I noticed after my trip though, was the two "blades" we plug in were closer to each other (they weren't parallel anymore) I kind of pushed them back to place but anyone can see the blades are slightly moved
Please help me auick this is very important!
EDIT : Usually I recharge my phone from 23h to 6h45,but today I noticed it only recharged when the phone is Off, and very slowly, it only made it to 51% merely adding the sentence cost 2% of battery while docked..

Probably the battery itself is dying?
S3 should be filly charged within 3,4 hours in most.
Or you may need to recalibrate your battery?
I have been into some situation like this:
1. 10% charging, after one time reboot it goes up to 50%, just in minute.
2. Battery from 95% drops to 50% with rate of 2% - 3% per minute.
What I do: drain battery to 0% and start fully charged it into 100% and then it seems to be fine through...
