Battery life is one of the biggest issues in the Android world today. Take your SIM card out, turn off Wi-Fi and never touch it and it'll sit there happily, lasting for a whole week on one charge. But try to use it for anything "smart" and, well, that's where the problems start.

It's a pretty sorry state of affairs when we count the uptime of today's smartphones in numbers of hours rather than days, with the standard metric of decent battery life being whether a phone can last a whole working day on a single charge.

So are there any realistic things you can do to improve your phone's battery life, other than just switching it off, putting it a sock drawer and hoping no one ever wants to call you?

Yes, yes there are. Of course it's not possible to suddenly double your Android phone's uptime by magically tweaking a few settings, but you should be able to squeeze out a few more hours of life from even the puniest of batteries without compromising on performance too much.

Here are some easy, not-too-compromising methods of boosting your Android phone's battery life.

Some of today's phones feature automation tools, which let you, say, turn off the mobile signal and Wi-Fi after a certain time. Putting your phone in this sort of induced coma will save power, so if your phone doesn't support scheduled activities, install a management app like Tasker and turn off all non-essential stuff over night. Or stick it in airplane mode yourself. You'll sleep better, too.

If your phone's constantly sniffing out and trying to connect to every Wi-Fi signal in the area like a robot dog on heat, you're wasting power. Switch off Wi-Fi when out and about or when you know you're not going to be needing it. A Home screen toggle will make this easy. Think of it as something boring but essential you have to do, like always putting your seat belt on.

If you're a keen Dropbox user or rely heavily on music syncing services, you'll benefit greatly from only doing your uploading through Wi-Fi. It's vastly quicker, which means less connectivity time for your phone and less strain on the battered old lithium reserves.

You can never be too sure what's running itself in the background, what with all the multi-tasking, self-uploading, auto-replicating features in today's modern Android apps, so at least minimise the chances of something randomly hoovering up all your battery by constantly trying to connect to some non-existent server, by deleting any unused or old apps.
