2. Alter your display's colour profile

A popular desktop app called f. The default brightness setting on phones may look good, but it's a big battery killer if you're constantly checking Facebook and Twitter throughout the day.

If you're indoors, you probably don't need the brightness set too high. When it comes to battery life, low brightness is better, but you may want to take advantage of the 'Automatic brightness' option so that your Galaxy S3 will automatically become brighter when you're out in the sun. Samsung has included a lot of clever features in the Galaxy S3, such as the ability to tell whether or not you're looking at the phone directly and adjusting the display as necessary.

But if you have this feature turned off, you'll want to check your screen timeout settings. Again, lower values are better for battery life, as your phone will conserve power by switching off the display when it isn't needed. When radios such as Wi-Fi and Bluetooth are enabled, they're constantly scanning for devices and making themselves available even if you aren't currently using them. Turning off these radios is as easy as pulling down the notification bar and switching the toggles at the top of the screen.

If you have the screen set to full brighness, you might find that turning it to auto might help with the batttery life as it'll be darker when you're indoors.

However, I do find that it takes a moment to react and that the screen isn't immediately visible in bright light when a call comes in. I've got auto brightness, 1 min timeout and power saving turned on on my S2 and it normally lasts all day. Remembering to turn wifi off when I go out helps, too.

Bluetooth is off, but GPS on for apps that use location though they can do that through the network too.

I have actually seem OS Services using quite a high percentage if the device has been inactive ie in my pocket for a considerable period. It doesn't itself actually mean the usage is high, merely that it's the highest user.
