Some users of Samsung Galaxy S3 Mini have been experiencing major problems with the device's battery life. The most common problems with the device involve battery drop and overheating.

Many S3 Mini users have been posting about their issues on various forums, reporting problems like, "My samsung galaxy S3 mini batteries suddenly drain within hours!" and "My battery drains like there's no tomorrow!"

Certain steps can be taken to increase the battery life of the Samsung Galaxy S3 Mini.

• Turn on GSM Only mode as much as possible: In case you are not using 3G, GPS, Bluetooth, or Wi-Fi, try to keep your device on GSM Only mode as it will enable you to use the basic functions of your phone, but help to greatly extend the battery life.
• Switch off Wi-Fi when not in use: When you are not using WiFi, turn it off, as receiving signals from an outside source may also put stress on the battery and even cut the battery life down by 50 percent.
• Switch off GPS: When not using GPS, turn it off, as it's nearly the same concept as turning off the Wi-Fi. Keeping the GPS on is also a huge strain on the battery.
• Close Camera App. Heavy battery drain will occur if the device is displaying a wide array of colors and images. Actually closing the camera app will save a major amount of power, as well as using it sparingly.
  
• Adjust display brightness: Keeping the screen's brightness at a high level drains the battery substantially, try to keep it as low as possible.
  
• Reject Android Live wallpaper: Similar to the camera app, the device's hardware consumes a lot of power by displaying visuals. Avoid this app at all costs.
  

Last, but not the least important, ensure that you that you maintain the battery of your device properly, as it will help to extend its life. Remember to clean the battery contacts at least once or twice a month. Also, use the original AC charger as much as possible and avoid charging via USB, because it could spoil your battery. Remember to charge your phone whenever it drops to 10 percent, and avoid exposing your phone to extreme temperatures.
