Dual camera smartphone, the Ulefone Gemini, has been equipped with a 3250mAh battery for 1-day use and it is also offering a super saver mode for long duration when the energy is about to run out.
From the latest video by Ulefone, we can see the super saver mode can be selected after holding the power key. Being activated, the super saver will close Wifi, data connection and most apps, only keep the 2G network for phone calls and SMS. When the battery life is under 10%, the system will notify you to activate the super saver mode, which is expected to enable approximately 1-day standby. The video also shows that in normal mode, half an our of FHD playback will consume only 8% energy.
