How we remove the battery from an Android tablet and replace it with a power supply circuit. This removes the "battery swelling" problem that Android tablets often have, and also saves energy, since there no heat generated from charging. It also greatly extends the life of the tablet, since it no longer needs to have a working battery, and batteries are usually the first thing to fail on a tablet.
