Battery and Memory Optimisation

1. Home Screen Panels
Use as many as needed home screen to avoid slowing down the LG G2. It is recommended to utilise the default home launcher for best performance.

2. Widgets
All widgets in the home screen and lock screen consume battery and memory which you should monitor regularly. Use widgets which you truly need and enable auto-syncing if necessary.

3. Live Wallpaper
No matter how fast and fluid the G2, make sure to use Live Wallpaper which are stable and eats less power. Live Wallpapers combined with several widgets can slow down the device eventually.

4. Brightness Level
Manage the brightness level to juice more out of the battery and minimise it before you go to bed for battery saving purposes.

5. Screen Time-Out
If you prefer the device to turn off its screen automatically, set the screen time-out to a minimum such as 30 seconds or 1 minute max to save power.

6. Removing Applications
Uninstall apps which you do not use anymore to clean the clutter to the RAM and battery. Some apps may contradict functions to one another, so be careful on downloading from the Play Store or any other sources.

7. Wireless Connection
Disable wireless connectivity such as Wi-Fi, Bluetooth, GPS and mobile data when not in use to prevent them from draining power.

8. Software Updates
Don't forget to check in regularly to the LG G2 Web site, on your software updates found in the settings and the default PC suite of the device for new firmware releases. New updates include stability improvements and battery enhancements.

9. Regular Reboot
Reboot your smartphone regularly after every full charge so that the memory and apps will get refreshed after an entire day of usage.

10. Backup and Factory Reset
Always create a backup of all personal files and information stored on your device to ensure protection if something happens. Performing factory reset may be needed if an error or technical issue occurs. Backup first before performing any reset.
