Phone losing signal, freezing and going off =/ - Galaxy S II Q&A, Help & Troubleshooting

Hi
I've got a problem with mobile signal, phone freezing. I'm charging my battery to full, everything works good, and when it's 40-15% I'm losing signal and can't connect to any mobile signal, in few moments my mobile is freezing and I need to restart it, but after it's freezing again. To fix it I need to put it off, put a charger and than power on, after that it works, but it's really annoying. Any solution? Should I buy new battery or try something else?
Thanks in advance.

did u tried factory reset... or reflash a stock rom wid odin... may b a software problem..

I'm in Liverpool about a week, and I think I should buy it on ebay.

I've got the 2000mah Samsung battery, and it's fantastic. Personally I wouldn't buy one which isn't in the original packaging, and that has the model number EBK1A2EBEGSTD. So yes, the 2000mah batteries are great, but look out for those things.
As far as your testing of another battery goes, you could borrow one out of a friends s2 and test before forking out on one.

[Q] Did I buy the wrong battery?

I had a friend order this for me from eBay. http://www.ebay.com/itm/ws/eBayISAP...1&ssPageName=ADME:L:OU:US:1123#ht_4820wt_1163
I know I'm supposed to release the power in the battery but my phone won't turn on with this battery.
Help?
I have a few like that, all mine work fine. The last one I bought was an i9000 too, it should work. Maybe you got a defective one.

The fix is to not buy silly fake Chinese battery's from ebay.
Completely agree. That's why I have the official extended battery. Pointless paying good money for knock off, unofficial, ****e batteries. Worth the extra cash for the original branded kit that will actually work.

obviously no help
Hindsight is the best sight but what do you want us to say, keep the battery under your armpit for 5 minutes and all will be well?
Does the phone start up with the original battery?

Obviously its your problem, not ours!
Maybe if you gave more relevant information you would get more helpful replies. All you did was tell people you're silly enough to buy a cheap/crap battery from ebay and then wonder why you get replies you did??

Then it sounds like your hardware has failed or you bricked it at some point.
What was you doing prior to your device originally losing power?
Have you tried different charger?
What rom you on?
What kernel you on?

[HELP]Battery problem Motorola XT912

Hi guys, I have a very big problem regarding to the battery. Sometimes it doesn't charge or maybe it's full charged but It drops from 100%, 50%, 20%, 5% and then die (in a few minutes). Somedays it works well but the average is not good. I tried several roms , full wipes and I changed the battery. I don't know what to do. Any thoughts?
Thanks in advance.
what firmware? that did before the problems started?
I believe your battery is damaged. Possibly from high temperatures. I recommend getting a replacement phone if you still qualify for the manufacturer's one year warranty.
thanks

Flying Jelly 3.01. But the issue is general. Sometimes I plug it in chager mode and shows 100% but when it boots drop to 50% (20, 5, so on) in a matter of seconds.

I already changed it so I think is not a battery issue. I'm trying to avoid send it back because I'm from Argentina and I bought it in China.
Another issue is when you connect it all the night but it doesnt charge. At the first I thought it was a software issue but right now I don't know what to test. I think the most weird is when sometimes works just fine. It's making me crazy...I dont know if send it back or set it on fire lol.
Thanks guys.

Hmm maybe there is something wrong with your actual charging port. Have you tried resetting your phone's software?
I think you should flash the stock. before flashing do wipe. in order to avoid the problem of software.
thanks

I did it several times. I don't know what is happening but since two days is working "fine". The last thing I tried It was die-hard battery script. A guy in another forum recommended me to use compressed air to clean out the ports because it may have a piece of debris that is causing a direct short therefore killing your battery.
Thanks guys.

Galaxy Note keeps rebooting

Maybe stuck power button........flick the back of your phone a couple times.
I know button seems to be fine, but that doesn't mean anything. Flick away, see what happens
Sent from my SAMSUNG-SGH-I717 using xda app-developers app
Ok tried flicking it to no avail. Any other ideas could this be a software bug or is it most definitely hardware? I'm thinking its software but obviously can't be sure
OK now I've got some more info on the issue. it wont reboot while charging and turned on, but it will if its charging and turned off. the only thing i haven't tried is a new battery is it worth me doing that? any other ideas or thoughts at all?
If your battery is close to 1yr old then yes! Try a new battery. They are really cheap online and its nice to have a spare charged battery ready for our resource hogs.

Where's the best place to get a cheaper battery? I looked on ebay and they have some but i dont know if i trust i did search oem, but at the smae time dont wanna pay 30$ for one from at&t
Ebay is cheap! But yes some vendors aren't very trustworthy, or prompt. I stick to a close vendor when on eBay.
There's always Amazon. Very reasonable. Lots of users on here like the anker 2700ma battery and swear by it. The stock battery is 2500ma.

OK just for an update i have done absolutely everything i can software wise tried all 3 version of stock (GB, ICS, AND JB) the problem still continues so now I go to hardware. I'm gonna try a battery, and look under the hood at the power button and the rest of the main board. And if the battery doesn't work, then I'm thinking I will try to switch out main board. I really think this is a software issue as it does it when the phone sleeps no matter how it does it but all I can do is tinker and find out lol. I'll keep updating for everyone who has this problem. I appreciate all the help
OK another update i got it opened and played with the power switch it seems to be just fine but i blew it out with air just to be safe problem still continues i should also mention that i broke the sim slot right when i got the phone and i noticed the rebooting the next day but i doubt they are connected so im gonna fix sim slot, then go from there i have a standard battery and an extended battery problem continues with both of them so im going straight to motherboard as i think thats the issue anyway. Ill keep this thread updated

i9300 Screen flcikering and battery death

Hello,
First of all im new here and a complete Android noob. I know some stuff, but kinda just the basics. So have mercy with me!
My S3 is now about 1 year old, maybe 2-3 months less. Everything worked fine, until I installed the stable release of CM 10.2 that recently came out. Now the display starts flickering, when I have about 25% battery left, after a few seconds the phone freezes completely. It remains in this state for several more seconds, until I shut it down or remove the battery. When I hang it on the cord to load it seems that the battery is deadly empty, after a minute or so it has enough juice to start up again. Strangely, now it tells you, that you have like 1-2% battery left. So now's my question how I fix that. I mean either CM has some heavy issues with finding out how much power i have left or the battery is slowly dying.
Warranty is no option ---> installed a custom rom.
I know that there are many threads about a screen flickering issue, but I don't think that these are adressing my problem.
I hope you guys can help me and a bih thanks beforehand for all those who try!
Do a full wipe and reflash, charge to 100% and test before you add any mods or apps. If still the same then go back to the latest stock rom and retest to check your hardware.
Having said all that, AOSP comes with some drawbacks that you must live with, but this sounds more like an issue with your particular set up.
i have exactly the same problem on Carbon Rom and Omni. On Sammy it didnt happen.

now the phone wont pass the boot animation, it boot loops. But i can enter recovery and download mode. I wiped and flashed again a rom. I think that the battery is fully damaged and not giving enough voltage so the phone can power on.
PS: a battery will arrive today so i can test the phone then.

Try to test NFC.
The original one will work with it since it has the NFC chip, but not the fake one (if it is fake).
