That sounds suspiciously like a dying battery.  How long have you have the phone and roughly how many times has it been recharged?   Also, has it been allowed to run flat at all?

Ive used different batterys same thing happens

Hi, I have seen a few reports of this and I suffer from it occasionally. I don't think it is the phone or battery as it has only been an issue since the last update and I've seen people who have rolled back to 4.0.3 and do not have the problem anymore.

I have held of hard resetting the phone as this doesn't work and hopefully we may see the Jellybean update which I would hope cures the problem.

I have noticed that after the phone restarts and reports a low battery the percentage will then increase rather than drop, this also leads me to believe it is a software issue.

If you wish to rollback to 4.0.3, The Soup Dragon has written a very easy to follow guide and links to all files required.

Hope this helps

Hi jamollawop,

hrym may be correct here - are you able to try the handset with an alternate battery to see if this helps? Your nearest Vodafone store may be able to test this instore for you.

I think there's been a mix-up between a "hard reset" and restoring the phone. A hard reset does not usually wipe data from the device - unless there is an underlying issue - or take time to set back up again. It just acts like a forced PC reboot.

 - Switch the handset on
 - Whilst powered up, remove the SIM card and battery
 - Put the battery back in and switch on
 - Wait a couple of minutes, then remove the battery again
 - Replace the SIM and battery and switch back on 

At the same time, it can be worth restoring the device to factory settings, especially if the issue started following an update. Even if it doesn't work in some cases, the same symptoms may not be caused by the same issue, so it's always worth trying any available options.

The other thing to try, of course, is whether the phone will switch on when plugged in and on charge.

If it is firmware related it would be the phone giving the wrong battery stats, you could try to wipe the battery stats using clockwork recovery , that's if you don't mind doing so, what model is yours??

Hi there.
I had the same problem recently.
The phone would get very hot and the battery would drain very quickly even when I wasn't using the phone. I changed the battery, but the problem persisted.

I noticed that the media app was using a lot of battery and I couldn't stop it

I also noticed that the problem arose fairly recently after I had started to use free anti virus software app from AVG..especially when it kept trying to get me to upgrade to the Pro version.

Solution. I un-installed AVG pro that I had on trail and the problem was solved.

No factory reset was required.

The battery now lasts all day long.

To make the battery last longer:-
1. Drain the battery 100%
2. Charge it with the phone off
3. Switch it back on and let it charge to 100%
4. Switch the phone off and repeat step 3.
5. Your phone should be okay now
6. Remove as many apps that you don't need.

This hopefully will make my phone last a bit longer. .

Update,



Today I reinserted my 32GB micro SD card to see it this caused any problems. The battery drained a bit faster but not as bad as before.



I have just reinstalled Daily Roads Voyager DRV, and moved it from the SD card to the device storage, and guess what, my phone switched itself off....so I have moved it back and all seems to be fine...at the moment



Maybe this was the culprit and not AVG?....



Now when I think about it..I remember some months ago when I used DRV in my car (without the USB charger connected) that the phone was V hot....will investigate further.....

Okay, My phone switched off So its definately the DRV app thats causing the problem....just removed it so mets see what happend now...
