These tips will help you to save battery usage and prolong its life. As different users has different needs, some of the tips might not be applicable. You can easily check the battery usage at : Settings > About phone > Battery Use . The screenshot below might differ from yours but it gives you a good idea what application is most using your battery

Or you can check up  “Spare Parts”  on the phone. If not available, you can download it from the market place. With this,  you can check usage on CPU, Network, GPS, Sensor, Partial Wake usage and others.


TIPS to increase battery life :
1.    Disable Background Data syncing : Settings > Accounts & sync > Untick Background data. Example is Google contacts, calendar which you can sync manually when the need arise.
2.    Disable Auto-sync : Settings > Accounts & sync > Untick Auto-sync , example Gmail and Facebook updates unless you need to be on top every minute
3.    Disable Always-On Mobile Data : Disable the Always-On Mobile Data option from Settings > Wireless & networks > Mobile networks > Enable always-on mobile data. This setting is on by default, and allows your phone to be constantly connected. But does it really need to be? If you turn the option off, you will still get push Gmail, and naturally multimedia messages and phone calls as well.
4.    Turn off wireless network positioning : To let your device learn your location via wireless network triangulation requires less battery than by using the GPS for this purpose. However, using both methods simultaneously is probably not a good idea from a battery point of view. The GPS can handle this task by itself, although it will get a fix on your location a little bit slower. Also, wireless network positioning will be used to collect anonymous Google location data, which will drain the battery further. You can change this option from Settings > Location > Use wireless networks.
5.    Turn on GPS only when you need it : You can deal with this by simply turning the GPS off (the Power control widget will come in handy), and by keeping an eye on your status bar: an icon will be displayed whenever the GPS is activated. Please note that there’s a difference between having the GPS option turned on from Settings > Location > Use GPS satellites(which shouldn’t use any power by itself), and having the GPS actually activated.    6.    Turn Vibrate Notification off: Settings > Sound & display > Untick Phone Vibrate
6.    Turn Off Haptic feedback: Settings > Sound & display > Untick Haptic feedback : Vibrate when pressing soft keys and on certain UI interactions.
7.    Reduce Screen Brightness: Settings > Sound & display > Brightness > Untick Automatic brightness > Reduce Brightness by sliding to left
8.    Reduce Screen Timeout Interval: Settings > Sound & display > Screen timeout (default 1 min) > Reduce to less than 1 min (15 seconds minimum)
9.    Disable WiFi : Settings > Wireless & networks > Untick Wi-Fi. The Wi-Fi radio apparently uses less battery than the 3G radio, and since 3G is off when Wi-Fi is on, you can benefit from always being connected to Wi-Fi if you’re close to a strong Wi-Fi signal. You can make sure Wi-Fi always stays on (even when the screen is turned off) by going to Settings > Wireless networks > Wi-Fi Settings. Press the Menu button, tap on Advanced, Wi-Fi sleep policy and select theNever option.
10.    If Your Phone Often Struggles to Find a 3G Connection, Disable 3G : it puts a strain on your battery. In case you live in an area where your phone often switches between GSM and 3G, you will probably improve battery life by simply disabling 3G altogether, and thus eliminating the need for your phone to try and find a suitable network. You can do this from Settings > Wireless & networks > Mobile networks > Network mode > GSM only.
11.    Disable Bluetooth when not in use : Settings > Wireless & networks > Untick Bluetooth
12.    Disable Unnecessary Running services: Settings > Applications > Running Services > Select and Stop any apps that you are not using
13.    Customise Data Options of Individual Apps : normally in Setting options of each app. Change intervals / frequency of data pulls or disable background syncing altogether. Pay attention to Twitter clients, RSS apps and mail especially.
14.    Avoid Live Wallpapers : These animated images though very nice and beautiful consume more power than normal standard wallpapers
15.    Amoled display : A Dark wallpaper will use less power
16.    Set a Reasonable Frequency for Background Updates :  it depends on the applications you’re using. For example you could set the Facebook app to only update once an hour rather than every 5 minutes.
17.    Turn Off the Weather App – This is a function that constantly pulls data, which in turn drains battery. Turn this function off by doing the following: ‘Menu’, then ‘All Programs’, followed by ‘Weather’. Then choose the ‘Menu’ option from within the Weather program and choose ‘Settings’ where you can disable ‘Update Automatically’. Now you can just pull Weather information when you want it.    18.
18.    Use the “BACK” button to exit apps rather than just hitting “HOME”.  Using “BACK” appears to store them as “inactive(cached)” apps, whereas “HOME” just leaves the app as “Background” task which  “appears” to use more CPU.  This is something I’ve only been playing with for a day or so, but seems to make a difference and is a good habit to get into.
19.    HTC Advice: Fully charge the battery to 100% charge (LED light turns green). 2. Disconnect the device from the charger and do not connect again until the battery is fully drained to 0% charge (red LED light will NOT turn on anymore). 3. Repeat the steps above for the first few days of initial use, then one to three times each month (depending on light to heavy usage) to maintain a healthy battery performance
