Again a video by Ulefone for the Ulefone Power 2. In a latest test by Ulefone, two units of the Power 2 were involved on a WhatsApp video call for half an hour. In the end, both phone consumed 6% of the energy. Theoretically, a single charge can give you more than 8 hours of videocalling, indicating that video calling will not be a problem for such a big battery. During the test the 2 phones have drained from 83% and 51%, respectively.
