[Q] Defective S2 battery measurer?

[brugernavn]

Hi, just to start i will say that i have been googling a bit before posting.

what i have:
A rooted European Galaxy S2 on stock ICS rom.

problem:

when i charge the battery full overnight and use it, the phone shuts off when the battery is 50% empty.

allright, there was some problems with the USB port thingy, so i changed the UI board to a brand new one. but that didnt help either.

allright so i rooted the phone and deleted batterystats.bin
didnt help

Then i let the phone charge fully when it was turned off.
when it reached 100% i pulled the battery for 2 minutes and put it back ind.
deleted batterystats.bin and started to drain the battery once more, but the same thing happens. dead when it reaches about 50%.

i have been trying with two batteries
the one I got with the phone, and a new one i bought 2 weeks back.

Now I'm sitting here with a phone that needs a new motherboard or what? :/


PS. Sorry for my bad english, I'm a Dane, youknowright?

btw. i attached a picture of the batterystats after i did the battery calibrate and was draining the battery.

Try factory reset if the problem is still tehre, I suggest to downgrade your system to Gingerbread.

Its either a f8888 phone hardware or something is draining the battery .

Use Better Battery Stats to check drainage but this is more likely hardware .

its a hardware fault, because it turns off when it reaches 50 pct. no matter WHAT im doing..

You said that you tried 2 batteries , can you test one of them on another Galaxy S2 or not ?

if not , can you test it using Multimeter or Voltmeter ?

the batteries can not be both faulty unless you have a very bad luck

returning your S2 to the service center is the best option unless your warranty is voided or expired then you have to pay for the service.

actually just tried a third battery that i borrowed from a friend, and that seems to be working fine, will write back later when i have made 100-0 run.
