Battery Care
The average lithium-ion battery life in a tablet pc is not unlimited.  These hints will help you achieve a longer lifespan for your battery.

• Always make sure you charge battery fully.
  
• Clean battery contacts occasionally. If your battery is removable, remove it and clean its metal contacts with alcohol, (ideally do this every two months), allowing it to dry thoroughly before replacing it. This makes sure the power transfer between the tablet and its battery is as efficient as possible.
  
• Keeping the tablet cool will extend battery life.  Try to operate on hard surfaces as much as possible and avoid using the tablet for long periods on your lap, pillows, or other soft surfaces. Never store your computer in a hot car or in full sun.
  
• Running a lithium-ion battery empty and subsequently giving it a full charge will keep a lithium-ion battery fit. (To completely discharge a lithium-ion battery simply run your tablet until it automatically cuts-off.) This will ensure your battery meter remains accurate.
  
• Set your screen brightness to the dimmest that you are comfortable with.
• When not using Wi-Fi, disable the Wi-Fi adapter.
• Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices. Do not buy a replacement battery until it is needed.
