Why Does My SPH-M620 (Upstage) Standby Screen Display Two Battery Meters?
The Samsung SPH-M620 (Upstage) handset features both an internal battery and an Extended Battery Wallet.
You have the freedom of utilizing internal Lithium Battery or the Battery Wallet. When device is connected to the Wallet, the charging priority is first to the phone and then to the Battery Wallet. While device is connected to Battery Wallet, it uses the extended battery and when disconnected it uses the internal battery.
