Deep Discharge
If you regularly just ‘top up’ the charge in your battery with- out ever allowing it to fully discharge first, its life will be shortened. In order to get the maximum life from your bat- tery you should allow it to discharge completely about once a month.
To discharge the battery completely:
1)Leave the phone switched on until RECHARGE BATTERY appears, then let the phone switch off automatically.
2)Leave the phone alone for about 30 minutes (and do not connect a charger within this time) after it switches itself off.
During this 30 minutes, the phone is in ‘Deep Discharge’ mode. The way to ‘wake up’ the phone is to connect it to a charger.
3)Fully charge the battery after Deep Discharge.
