Tips on extending battery life

2. Disable Wireless Network Positioning. You can turn it off from Settings • Location & Security • Use wireless networks.
3. Switch off Wi-Fi if you’re not close to a strong Wi-Fi signal for extended periods of time. This puts strain on the tablet.
4. Use a Quick Screen Timeout. You can alter this option from Settings • Display • Screen timeout.
5. Reduce brightness to a comfortable level using a widget or at Settings • Display • Brightness.
6. Use Web Widgets wisely. Widgets that access the Web consume more power than widgets that do not.
