  2. How do I maximize battery power on a BlackBerry® device?

    • Avoid exposing the battery to extreme heat and cold. 
    • For the first 3 charge cycles, fully charge the battery overnight and allow it to fully discharge before recharging (battery conditioning).
    • Charge and re-condition a battery after an extended idle period. 
    • A Lithium-ion battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours).
    • Keep your phone, batteries, and the contact terminals clean. The contacts can easily be cleaned with a pencil eraser.
    • Use the battery. If possible, avoid letting your battery sit idle for long periods of time.
