EVALUATION OF BATTERY DISCHARGE PROFILE FOR IN-SERVICE MOBILE PHONES

The performance of Lithium-based batteries in mobile phones is highly dependent on their usage profiles, among other factors such as aging, operating temperature, and internal defects. Since many applications and processes draw power from phone batteries in varied patterns, the usage patterns affect the life and performance of phones. This study will be collecting and evaluating battery discharge profiles under active phone operation to estimate the effects on remaining charge and the cycle life of phone batteries.
