Here we show some useful tips and tricks to
increase your LG Optimus 2X‘s battery life.1. Screen will always be your biggest drain. It uses more than 60% of your battery power. Turn display brightness down as low as you can (I set mine at about 15%), and setting the screen timeout to 15-30 seconds. You can also try black / dark wallpaper that uses less energy.
2. Do a software update – menu, settings, about phone, system software updates.
3. Install something like quick settings and place link on your main home screen, so that you can access quickly to turn say wi-fi and gps on/off.
4. Ensure any sync’ing the phone does, say email / facebook / maps, etc. is as required and not as often as the phone can. Mine checks my email every 30 minutes and I don’t use GPS unless I need maps.
5. Ensure USB debugging is turned on – this is mainly to reduce lag, but may well help with battery life. Go to menu > settings > applications > development, set usb debugging on.
6. Ensure your phone has a short screen timeout – menu> settings> power saver> screen timeout + settings.
7. Avoid Live Wallpapers. Animated wallpaper will keep the processor working all the time and it will drain your battery.
8. Turn off Wireless Network Positioning / GPS. Using GPS surely will drain your battery; use it only when you need it badly instead you use Assisted GPS.
9. Always Keep Bluetooth off When Not in Use. Bluetooth is obviously draining your battery if you keep it on all the time.
10. Streaming Apps Will Kill Your Battery. Audio or video streaming application (Youtube, Skype) will decrease you battery life fast.
8. Turn off Wi-Fi. If you don’t use it you better turn it off because it will suck up quite a lot of battery life.
9. If You’re Inside a lot, Having Wi-Fi Always On May be Preferable. Since 3G radio use more ammount of energy, so if you are always on hotspot area you can use your Wi-Fi instead of your 3G network.
10. If Your Phone Often Struggles to Find a 3G Connection, Disable 3G Keep searching on 3G connection will drain your battery.
11. Use Widgets Wisely. Terminate widgets that are unnecessary will save your battery life.
12. Turn Off Always-On Mobile Data. Disable always-on mobile data as it will decrease the battery use.
