Battery drain

[gt37]

I took your advice on here and finally got round to doing a Factory Restore. I had no data connection issues, but just to clear the phone of any unused files etc, it was becoming sluggish and freezing. As you say it's good for the phone. More the fool me believing a Factory reset was good for the phone, battery drain is back, cheers then. I did the reset a week ago, I have no auto syncs enabled, The Comms suite is not enabled, so why has it come back?

A factory reset will resatore the phone to its out-of-the-box state and wouldn't cause battery drain, though it might not solve it.   If you take the battery out and place it on a flat surface, can you rock it?   If so, it's dead.  Contact Samsung direct as they may send you a replacement without your having to send the phone away.

The battery is flat and not swollen, i had that problem 14 months ago, so i give up. I've taken some Apps off, shame i can't take the Vodafone and Samsung bloatware off that i do not use, probably what is causing some of the issues. As this is a unlocked phone, can i not uninstall Vodafone Apps? Or is the unlocked bit just for SIM cards?

If you look at Settings|About Phone, there's a section for the battery and there should be a chart of what's using it.  Does this provide any clues?   If not, I think there are 3rd party apps, though I've never tried any.   Usage tends to be shown as a percentage of the total and the screen and Android system are usually highest.

It's possible that an app or a service is over-acting, but this may not show up, certainly on the built-in battery monitor, especially if it's using core services.

If a factory reset fixed this previously, it does rather point to something of this nature.   It's difficult to say whether this is a fault or a usage pattern.   You could send the phone off for repair, but that'll mainly consist of a basic electrical test.  If it passes that, the OS will probably be reflashed and the device reset, after which it'll be apparenyl working OK.   There won't be time for an extened test, so you may not get very far.

The easiest way to see if it is the battery at fault is to fully charge it out of or in the phone and remove it, put it somewhere overnight on its own and put it back in the phone the next morning, if the power has gone or diminished then you'll know it's the battery at fault. Apps that are running all the time will be using battery power, as said, you can see what ones are using the most percentage and you can stop certain elements within an App but in doing so it may prevent the main App working properly. These phones are more like a pocket PC nowadays and to keep them performing efficiently and up to speed you need to keep them as 'clean' as you can and keep cutting out the dead wood.
