Battery percentage jumping or inaccurate on Android
Your phone's battery gauge is confused about how much battery you actually have. This is a sensor that needs recalibrating, not a broken battery. A full drain and charge cycle fixes this for users.
Your phone estimates battery percentage by checking voltage. Over time this sensor gets out of sync with what is really in the battery. It is like a fuel gauge that reads half-full when you are at quarter-full. The battery works fine, your phone just does not know what it has.
- ✓Have a charger ready — you will need to do a full charge cycle
- ✓Make sure you have 1-2 hours available for a complete drain and charge
- ✓Keep your phone plugged in during the charge portion so it does not get interrupted

Skip, I just want a technicianCommon mistakes to avoid
- Charging to 100% constantly. This wears batteries faster. Keep it between 20-80% when possible
- Interrupting the drain-and-charge by using the phone while it is charging. It will not work if you do not let it complete
