Video: No Problem for A Day – Ulefone Vienna Drainage And Charging Test

Posted in Apr 7, 2016 in News, Smartphones, 1 comment

Our HiFi device Ulefone Vienna packs a 3250mAh Sony li-polymer battery, which is expected to offer the energy for one-day normal use without problem. And our latest drainage and charging test has proved that.


Playing an online HD video for half an hour, Ulefone Vienna drained from 34% to 24%. On this basis, we can expect heavy use of xx hours on a single charge while one day of normal use should be out of question.  Here we promise that you don’t have to worry about energy performance with the Vienna.

Now the presale promotion for Ulefone Vienna is still ongoing while you can pay only USD169.99 for the amazing HiFi audio quality, Sharp FHD display, 32GB storage besides MTK6753 octa-core 64-bit chipset, 3GB LPDDR3 RAM, 13MP Panasonic camera and infrared emitter.

    2016.04.08 Greetings! ULEFONE VIENNA .You have me confused. First you are saying that playing HD video for only 0.5hr uses about 30% of the battery. At this rate it will play only for 1.5 hrs – if that. Then you came to a somewhat contradictory conclusion that in normal use it will last all day without any problems. How is that possible?
