How long does it take to fully charge Phone (2a)?

The charging current of Phone (2a) depends on the temperature, which, in turn, affects charging. Both low and high temperatures slow down the charging speed. Chargers with different protocols have different charging speeds and charging times.

For an optimal full charge, use a PPS protocol charger – ideally the Nothing charger – and charge the phone at room temperature (about 25°C±3°C) with the screen turned off for about 1 hour.
