Nokia 252 owner manual Deep Discharge, To discharge the battery completely

The repetition rate of the battery-low warnings depends on the remaining battery capacity and the battery condition. The warnings are more frequent when you’re in a call.

Note: If you’ve selected the Vibra Only or Silent Ringing Option, you won’t hear any warning tones. See “Ringing Options (Menu 3 1)” on page 37.

When the battery charge is too low for the phone to work, the phone displays RECHARGE BATTERY, then beeps, then shuts itself off.

Charge the battery as described earlier in this section.

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.
