Prolong battery life
A battery lasts longer and performs better if you fully discharge it from
time to time. To discharge your battery, follow either of these steps.
•
Leave your phone switched on until the battery drains completely.
Ignore any messages to recharge your battery and let the battery
completely discharge.
•
Or, use the battery discharge feature of any approved accessory
available for your phone.
Important: Do not attempt to discharge the battery by any means
other than those just described.
