Ulefone has equipped their 2017 flagship Ulefone Gemini Pro with a 3670mAh li-polymer battery, which is supposed to offer the energy for one-day use. About its performance in real use, Ulefone has made a test to show users.
The test was composed of 5 projects, most of which are energy-hungry, lasting 4 hours in total. After 1-hour online video playback, 1-hour online music, 30-minute Wechat video call, 30-minute FHD video recording, and 1-hour gaming, Ulefone Gemini Pro consumed 34% of battery, indicating that normal use for a day is out of question. This test also says that Ulefone has made a progress in energy efficiency optimization for their flagship which packs Helio X27 deca-core CPU with clock speed as high as 2.6GHz.
