This morning I used my sister's Samsung Champ's charger to charge my Galaxy 5. I didn't keep it in for long (20 - 30 min) but when I removed it, the battery started showing low charge warnings; I tried charging with my laptop using the cable that came with the phone and it showed 70% charged immidately, but when I removed it, it showed <14% warning again.
I tried to drain the battery completely and then recharge it, but the battery is still draining fast. Please help, the phone is only 2 months old...
Did you do a full charge?
I don't see why using other chargers effect your phone, I always use blackberry chargers and have no problem, try charging to 100%, draining to 0% a few times, see if it helps

It might have nothing to do with using the wrong charger, you might just have the signal glitch where your phone is constantly searching for signal when it already has it, my phone started to do it recently, to check if this is the issue go to Settings, Phone Info, Battery Useage, Signal, then if it says something like Time without signal 50% then that is the issue.
Try this;
Unplug your phone
Turn Airplane Mode on for about 10 seconds
Turn Airplane Mode off
Restart phone.
That fixed my battery life- it was going for 80% battery to 10% in under 5 minutes.
Ok so I have a galaxy s3 gt-i9300, which is about 20 months old, and it started to have this problem a month or so ago. The phone was running a kit Kat cyanogenmod rom, and it was draining the battery somewhat faster than the stock rom, and one day the screen started flickering at around 30% battery, which followed by the phone turning off itself. It can't be turned on until it's plugged in, and when I do so, the battery is at 0% charge, so I figured this was a battery problem and I replaced the battery for a new, original samsung battery. I thought this would make the trick. But I didn't, so my last thought was to return to stock software and this didn't solve the problem either. This always happens to me in every single charge at around 30%-40%. The rest of the charge lasts as long as expected, so the phone basically uses 60%-70% of a charge. I'm all ears for solutions to this and I also want to know what is causing it.
Try a battery from another phone, one that is known to be working correctly.
Else try a full wipe, including preload and internal sd, before you flash the latest stock rom for your country. Factory reset again in recovery after flash.
Hey, I have an S2 (fairly old I know, but can't really change my phone right now :/). Since a few months back I started having problems like the phone shutting down at 12-15% battery left, reboots sometimes consumed 10-15% of the battery. So I bought a new battery but the problems continued.
Now leaving those problems aside, since a few weeks ago my phone started to discharge even thought it was connected to the charger, so I when to see a tech guy and he told me the charging port was loose so he fixed that apparently, bought a new charger after that but the problem persisted, the phone charges sometimes and sometimes doesn't and when it charges it takes hours to reach 100%.
Another thing it's that sometimes I left the phone charging at night and when I wake up the phone says it's 100% but when I take off the charger it drops down to 70-60%.
I'm using 5.1.1 so I thought it could be a ROM problem since Lollipop is a battery killer, I decided to change from Paranoid to CM but still the same story.
Now I'm trying to charge the phone while it's off and seems to be working, although very slowly.
I had the same problem with a Xperia X8, I've changed the battery and flash the stock ROM. Try to do this
I get service from Qlink. They sent me a refurb as all their phones are refurb, Sprint Samsung Galaxy S2. It came with 8 or 4gb and a 1400 battery or something. A much smaller battery then the retail phone.
Ever since I got it, it won't hold a charge. I don't remember if this started right after I got it because it took me a long time to notice it won't hold a charge. I'd charge it and when I would shut off the phone and try to turn it on a few days later it wouldn't boot. I'd have to charge it for hrs before it'd even boot. When I shut off phone it would always have over 70% battery. Then I notice it says connect to charger even though it is.
Then all of a sudden it stopped charging. I have a 4 port smart charger and cable that has no problems with my other android phone which is an unlocked Moto X Pure or my iPhone 6s Plus.
I ordered from Amazon a sprint galaxy s2 battery. Got it. Plug in and charge many hrs. Turn on. Battery shows about 93%. Turn off phone. Les then two hrs later I turn it on and lost 4% charge to 6%. That doesn't seem right. Turn off phone. Next day phone won't turn on. Hold power and vol down says no battery power. Leave it charge for hrs. Won't turn on. Finally it turns on. I notice battery going down 1% every 10 minutes or less. Not right. Just sitting there.
Then I notice it looses battery % even while charging. % went down. Now when I try to charge it don't work. It powers on by itself. Says connect charger. Shuts off. While later it powers on again and keeps repeating this every so often.
Also when it was on once, it opened calendar even with me not touching it. It would like open it and go to home screen by itself. This after a factory reset.
Now it won't charge. Just does the above turn on then off every so often.
I am clueless what's going on. I wonder if I must get another phone which cost $25. They send anything. All used crap non hd phones. Qlink is a lifeline program thing.
Install android n, of that doesn't entirely solve it, get an unofficial high capacity battery.
Found the original charger and cable. Now when I charge you see the big battery with dots under it when the phone is off. So that's good. Why don't you see this with other chargers?
Battery now seems to work and hold the charge. I don't get it.
I don't think the phone can update to any newer then what's on it now. It's 4.something. Nothing of 5.0 when you check for updates. I think the phone is too weak for 5 at good performance but I don't know.

I think he meant installing a custom ROM. There's currently one Cyanogenm... Lineage OS 14.1 for the Galaxy S2. It is based on Android 7.1. If you are curious, check out this link: https://forum.xda-developers.com/showthread.php?p=68771297
Nice to hear that your problem seems to be solved! I am a little bit surprised, as I often used different chargers without problems.
Why won't it hold the charge long?
With official cable and charger and batter it came with from lifeline program it looses full battery while powered off in like 3 days. And gone from 94% to 87% in less then 30 minutes.
What's going on?
Then one week it'll be fine.
Me too, i have the same problem too , and I'm charging my phone almost 4 times in a day
A few weeks ago, my phone started to shutdown by itself while my battery charge would show from 30 to 70 %.
So i ended up recently by ordering a new battery.
I did the replacement and now the problem remains with the new one.
Before starting using it i pluged the tel for charging and it got 30% in 1 or 2 hours and then got suddenly full charge.
This is the very first time i experience this strange behaviour.
My phone has the B396 build and is rooted.
Is there anything i can do to make the OS see the real battery charge ?
