What to do
- Avoid heavy use (games, video) while the tablet is charging if it's getting hot.
- Charge in a cool, shaded, well-ventilated area, not direct sun or under a blanket.
- Remove any thick case while charging, since it can trap heat.

When to call a pro
If overheating continues even with a proper charger, a cool environment, and light use, a repair shop can test the battery for damage or excess resistance.
Safety
Use caution
Stop charging immediately if the tablet becomes too hot to comfortably hold, feels swollen, or the case is bulging, and let it cool in a safe, non-flammable area.
