I've had a Sony Xperia SP for a few weeks now with no problems until today, the battery has drained very quickly and the phone feels quite warm. I haven't downloaded anything recently which would drain the battery, any ideas?

I believe that this is one Android weaknesses, it's advanced multitasking capabilities means that apps can still stay active in the background and drain the phone.

It could also be a rogue app, have you checked the battery usage section?

Not sure if totally serious; Android doesn't even begin to have "advanced multi tasking capabilities". Its not even vaguely desktop class .... which is strange for a *nix based OS (same can be said for iOS).

Its likely much simpler; my son has an SP. Battery life started to get pretty bad, but it was down to two settings :

1 - Enabled Stamina mode. iirc it disables wifi and data when the screen is locked.
2 - Screen timeout. It wasn't actually enabled by default, so the screen was staying on ...

Change these and battery life was massively improved.

I didn't say desktop class, I was referring to mobile class because after all it's not a desktop rival. Maybe I should use the term background processing rather than multitasking. Android gives the developers more options for running background processes or services than it's rivals, which is advantageous but also causes issues when coded badly or something goes wrong.

Why should android needs stamina mode, when iOS can handle wifi, Bluetooth and GPS on permanently without battery drain.

Thanks for the advice, only thing I could think of was using lead from my old phone to charge it last night by mistake, would this have any effect?

Restart the phone and the rogue process should stop. See if the behaviour occurs after activating a certain app.

Yeah sounds like some crashed app stuck in a processor loop or something

Depending on the phone and the lead, its possible that it simply refused to charge.
With any new 3rd party lead its best to first check that charging does not stop after a few seconds.

Multi tasking on Android isn't really that advanced; the way its handled on the Playbook OS2, or on BB10 - that is advanced. Androids multi tasking is similar to that of iOS, but not quite so restrictive.

iOS doesn't handle wifi, bluetooth and GPS on permanently with no battery drain - that isn't what I've experienced on my 4S. With location services enabled and wifi on, it can barely make it through a day. If I had bluetooth on it definitely wouldn't make it through a day.

Stamina mode on the Sony kit is just a handy option that can dramatically improve battery life, as out of the box the SP doesn't appear to be that well configured.

I switched off and recharged the phone and seems to be back to normal thanks.

There has to be a reason why iphones are twice the price of an Xperia SP and its because you don't need to turn of wifi etc to save your battery. Still doesn't explain why this phone is half the price of lots of others though??

OP, have you actually checked which apps are running? (i.e using up RAM - random access memory)

list them here
