Notes for charging your phone’s battery:
When charging your battery, keep it near room temperature. Never expose batteries to temperatures below 0˚C (32˚F) or above 45˚C (113˚F) when charging.
New batteries are not fully charged.
New batteries or batteries stored for a long time may take more time to charge.
Motorola batteries and charging systems have circuitry that protects the battery from damage from overcharging.
