To replace the battery of a Samsung Galaxy Mega 6.3, one should remove the battery cover from the back of the phone. Once the cover is removed, the owner should gently grip the top of the battery to remove it from the bay and insert the replacement.
The Samsung Galaxy Mega 6.3 is one of the last generations of Samsung devices to offer a removable battery. Users can easily purchase replacements from online vendors such as Amazon.com. The 3,200 milliampere-hour battery supplied with the device is rated for 60 standby hours, 20 talking hours, 8 web browsing hours and 8 hours for video playback. A user who seeks more life out of his battery than the battery is capable of should consider picking up a replacement that offers an extended lifespan. Most of these range from a smaller 4,200 milliampere-hour capacity to a larger 10,000 milliampere-hour capacity.
Installing more applications affects the overall battery life and the device's performance. Users should consider the purchase of an extended life battery if the device receives heavy use or many applications are installed. Extended life batteries run within the same price range as a factory replacement and require no special installation instructions. Users who decide to purchase an extended life battery follow the same replacement steps as they would with a factory replacement.
