  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).
