1. Set the minimum time for screen timeout!
This setting for screen timeout instructs the device to turn off the screen after a certain time period . Although this setting differs from phone to phone, it is in general a good idea to set the length of your screen timeout to the minimal time possible to guarantee that the phone does not drain unnecessary battery life when we forget to place the phone on Standby Mode
2. Play around with the brightness settings for your screen!
Play around with the brightness slider to approximate which brightness level is the most comfortable for you to be able to see your screen. Most people can see an Android display quite well with the backlighting turned off indoors. Perhaps this might work out for you too. This can potentially help to maintain lots of battery life.
3. Know what is hogging the power!
Firstly, in order to find out what to turn off, we need to know where the resources are being allocated. In general, you will discover that most of the time the biggest power hog is the video display.
4. Turn off the Wireless, GPS and Bluetooth features when not needed via Power Control Widget!
For the Wireless, it is advocated to be off when not in use. It should be noted that even if the phone is not connected to a network, the wireless networking transmitter will still proceed to search for available wireless network on a periodic basis and this depletes power.
The Bluetooth functionality works in a similar manner as the Wireless functionality above. For Bluetooth, the device will try to search for nearby Bluetooth devices automatically on a periodic basis. Turning this off explicitly will ensure that this automatic functionality will not cause consumption of unnecessary battery power.
When the Global Positioning System receiver in your Android device is active it looks for satellites, and its processor prepares information to be sent out to any application that needs it, regardless of whether an applications programme that uses GPS is running or not. Similar to both the Bluetooth and Wireless feature, if not in used, this should be turned off explicitly.
As of Android 1.6, there is a widget that you can place on any one of your home screens that provides you quick control buttons for Wireless, Bluetooth, GPS, Push Sync, and screen brightness. It is highly recommended to just enable the Push Sync functionality via this widget for support in receiving emails.
5. Use Advanced Task Killer for termination of unused apps!
For a hassle free, stable applications programme to help you in managing the termination of unused apps to conserve power, the Advanced Task Killer is highly recommended. This is bearing in mind that all these unused apps might be running background processes for data processing preparation even when you are not using them.
6. Staying “Plugged” In! .
This may not be a tweak but we will like to bring out this point for the clarification of a common misunderstanding about “over-charging” a battery and causing it to be less effective. Li-Ion batteries do not suffer from the “memory effect” where a battery may hold less electric charge over time or after being over-charged. As such, it is alright to leave your phone plugged in, even after fully charged, though it does waste electricity. There is also some discussion going on involving whether powering off your phone prior to doing a full recharge will help to improve battery life but this has not been determined .
Hopefully, after applying the above 6 points for your Android, it will significantly increase your battery life and help to improve your Android experience!
