Samsung GS2 weirdness

[pinkyfloyd]

OK bear with me lads and laddettes of the hallowed halls of BCF!

Recently, and I mean in the last 2 weeks or so the phone screen flickers and then switches itself off. No warning apart from the flickering. When I turn it back on I get the battery critically low message.

Odd thing is I just had the above happen and was looking around on google and found various reasons including one that mentioned taking the battery out and checking it for bumps (warping). I done this, put the battery back in after realizing it looked fine and turned the phone on to find I had 75% battery. Just 2 minutes before it was telling me it was critically low!

Any ideas? I'm due an upgrate later this year but I would love to stick with the phone.

I don't suppose you have any friends with this phone who would let you borrow their battery for a bit?

I don't know about the S2 battery (haven't even researched it), but some batteries contain circuits which can go dolally, explaining the varying voltage readings.

RAM maybe failing. Could be a number of things.
If it is rooted (even if it isn't) see if you can download a memory test from play store
the battery thing is likely an incorrect reading. Quite common to happen after system crashes.

I had the same issue happen to me. In my case it was the battery that was the issue so may be worth going on amazon and getting a new one. I think mine was about £4 and that solved the problem.

Not guaranteeing this will work for you but might be worth a try for less than a fiver.

Back up everything you hold dear and prepare for imminent eMMC failure..

Mine did this just before Christmas. Luckily, it was still in warranty, took it to an O2 store. They sent it off and it returned with a new mainboard.

My battery started dying quickly, 6 hours from 100% to 0%

Changed battery, same issue. In the end, turned off background updates and everything is ok again. Something, never found what, was hammering the data connection and killing the battery.

Does not match your issue exactly, but might be worth trying.
