In this post I'll give you tips to save your Android's battery and a How to get A FULL DAY lasting battery?

:)

Common tips:-

#1 Uncheck the Auto-Brightness and keep brightness to as low as 10%, also lower the screen timeout to 15 or 30 seconds. Add Power Control widget to your homescreen (comes preloaded with most phones). So you can increase brightness whenever necessary.

#2 don’t use Live wallpapers, If possible keep your background completely black, Black color is battery-friendly as well as eyeball friendly.

#3 Don't keep Mobile data (2G/3G)/Wi-Fi/Bluetooth always on, simply turn off whenever not required.

#4 GPS is another biggest battery eater. Don't turn on GPS unless you need accurate data (for navigation).

#5 Turn off (or keep at least 1HR time between auto-refresh) BACKGROUND SYNC from social apps/web app, If you really don’t need them. e.g. Facebook, Twitter, TapaTalk, G+.

#6 Turn OFF vibrate/Haptic feedback feature as it consumes a lot of juice.

#7 Use WI-Fi whenever available (at home), it impacts less on battery then mobile data connection.

#8 Disable bloatwares on your phone e.g. Samsung's S apps WARNING: Don't disable important system app.

How to do this...

Go to Settings->Apps->All apps->Select app(e.g. Samsung apps store)->disable.

#9 Weak cell signals may cause battery drain to increase dramatically, because radio will try a lot to establish connection. So if you know there is very few possibility of getting connection then better turn on the Flight mode temporarily.

#10 Don't use WEB based widgets unless you really need them. They increase load on CPU and indirectly on battery.

#11 Some apps wakes your device partially to collect data aka a "WAKE LOCK". This happens many times in day. Run the app Wake lock detector and find out which app is causing too much wake locks. Wake locks increase battery drain. IMs are generally biggest source of wakelocks, Google apps are second.

#12 Don’t use task killer/RAM Boosters. Why?

Android generally stores data from apps which you started recently as Cache. This helps to improve loading apps quickly. If you kill any apps manually, some apps will restart automatically and finally impacts a lot on battery and CPU soon you will find your phone laggy.

#13 Reboot your phone at least once in week. (Press and hold power button —> select shutdown -> wait untill it shuts down -> to start again press and hold power button)

#14 Remove additional accounts (setting->accounts) from phone if you don’t use them.

#15 Don't let your phone getting too much hot. This improves battery lifespan.

#16 If you have 3G connection then Switch to GSM (2G) while browsing and switch to WCDMA (3G) when you want to download files or want to surf faster. Use Opera mini browser for just browsing its way faster than others and light on resources (battery, CPU)

#17 Turn off Auto-Rotation when not required.

Still you can’t get a day long battery then carry portable power banks :P
