The charging time of the Phone depends on temperature and the charger used:
Temperature: Both low and high temperatures can slow down the charging speed. For optimal results, charge at room temperature (about 25��C �� 3��C) with the screen turned off.
Charger Protocol: Different charger protocols offer varying charging speeds.
To achieve a full charge in approximately 1 hour, use a PPS protocol charger, ideally the official Nothing charger.
