Samsung Galaxy S2 battery problem. Any advice?

Anonymous — Sun, 02 Dec 2012 12:48:03 GMT

Over the past week, my Galaxy S2 has experienced a recurring problem: when I am using an app or browsing the internet, the mobile suddenly switches off.

Prior to this happening, the battery is usually between 50-100% charged, so I know it's not because I have low battery. When I switch the phone back on I receive the 'battery critically low' message. If I leave my phone switched off for a few minutes - half an hour and then switch in back on, I either recieve the 'battery low' message, or the battery life seems to be restored to it's previous level.

This has happened 5 times whilst using the arriva-m ticket app (twice) and the internet (google, 3 times).

Has anyone had a similar issue? I'm suspecting that the battery or mobile itself may need looking at. I've had it for 15 months (2 year contract). Should I contact O2 directly or Samsung?

Thanks

Is this the supplied 1650mAh battery?

You should try letting it run down to beyond 1% and charging it for about 3 hours over the charge cycle.

What I did was get a replacement 2000mAh samsung battery to get a bit more juice out of it.

Also make sure the contact terminals in the battery enclosure are clean.

Thanks for your reply.

It's the 1650 mAh battery supplied with the phone. I also checked the battery connectors and they seem ok too.

I do run the battery down to beyond 1% before charging and usually charge over night.

I'm wondering if there is a fault with either the battery or phone. It seems like the phone can't handle running certain applications and just shuts down. Then after a short time, I can switch it on and it's fine.

Yes, I'd agree with it been a battery issue.

A belated thanks for the replies.

I'm bumping this message for a number of reasons:

1) I've read several posts from other S2 owners who have experienced similar problems (if not identical). The advice given here is to either perform a factory reset, update the software or send it to o2/Samsung for a repair.

I've updated the software as far as I can tell (going on the about phone, software update sceens on my S2).

2) I have also popped into an o2 shop when visiting relatives where I was advised to send it off for a repair as it sounded like a 'software issue' (I would have done it there and then but it was in a city miles from where I live.)

So, with the different advice I'm not sure what to do - going to call o2 after new year and probably end up sending off anyway.

Thanks again.

A factory reset is the first thing to do as this will eliminate any OS conflicts. You should do it from the recovery menu (Vol Up + Home + Power). After this, if it is still failing you should contact Samsung or O2 for a repair.

I over come this problem by running my phone flat and turning it off and charged it over night. I've not had a problem since. I did this not long after the ICS update.

The factory reset seems to have done the trick. Thanks! 🙂

hello, can you let me know if you have had any further issues since your factory reset in January? I have had my Samsung Galaxy S2 for 18 months, and have started getting the identical issue as the one you described in your original post...phone keeps switching off when using internet/apps, even when battery is charged, when I turn it back on, it says battery is low....been happening all week, very annoying, but I am a bit reluctant to do a factory reset unless I know that is going to fix the problem...

I have had the exact same problem, for me it seems to be related to having mobile data activated, anybody else made this link? If I deactivate data the battery lasts MUCH longer, when active the battery dies rapidly and the phone has been known to crash/reboot. I am sending in for repair, fingers crossed they can fix it.

It sounds very much like you have a problem app that's draining the battery when you have data enabled. Worth checking and deleting anything you don't need.

I thought similar, but have been through my apps and doesn't seem to be linked to any one in particular.

So I've been having the same problem as everyone else (phone keeps suddenly turning off even when there's enough battery, always when I am using internet/apps) so I went ahead and did the factory reset. Removed everything, and reboot the phone. And guess what - the problem persists. So I don't think it's to do with a problem app.

What can cause the phone to turn off suddenly, only when I am on the internet or using apps? I am thinking this is actually a battery issue, or maybe a software issue that the next upgrade may be able to fix? Thoughts?

To confirm, DOING A FACTORY RESET DID NOT SOLVE THE PROBLEM.

I would flash CWM recovery and use this to clear your Dalvik cache too...

Hi everyone

I had this problem too after the last upgrade. As soon as wifi and mobile data were enabled my battery just drained in just a few hours (previously it was days)

Turning wifi and mobile data off would pretty much allow it to get through the night so at least my alarm worked but it was far from ideal. The phone also got very hot.

I read lots about factory reset and other fandangled things that would help. I downloaded a few tools/ apps that analysed various bits and pieces and was all set to do the "reset"

However I stumbled upon the solution by accident last minute. My Google maps had got in a real pickle and when I went in I disabled the button about giving Google access to my location, I then fully charged the phone and restarted it (removing the cache), since then battery has been perfect. I have even re-enabled the Google location stuff, wifi and mobile data and I have used only 10% in about 12 hours with minimum use.

I am sure it could be hundreds of rogue apps that might cause this, but it is well worth trying this first before doing anything drastic.

On the plus side I have also read a lot about how to keep battery life working for longer so have since changed many power settings, downloaded a black background and also just ordered a brand new battery.

It looks like the S2 will live on for some time yet.
