YotaPhone battery lasts 'up to 85 hours'

New dual-screen device has a battery life of more than 50 hours in reading mode, and 85 hours in flight mode

YotaPhone, the new dual-screen device from Russian start-up Yota, has a battery life of more than 50 hours in reading mode, and up to 85 hours when the phone is in flight mode, despite only having a 1800mAh battery.
At its launch event in Moscow yesterday, Yota chief executive Vlad Martynov said that the LCD screens used in most mobile phones use up a lot of power, meaning that they constantly have to go into sleep mode.
YotaPhone has an LCD screen, but also features a second e-ink screen on the back of the device, which uses very little power and is always on. This means that for certain applications like reading books and navigating using maps, users can switch to using the e-ink screen to extend battery life.
If course, it is unlikely that anyone using the Yotaphone would use the e-ink screen alone - the whole idea is to be able to quickly switch between the two. Martynov said that if the YotaPhone is used as a regular phone, the battery life will be equivalent to that of any other premium Android phone (although a number of premium Android devices now have 2100mAh batteries).
However, having the option to use the e-ink screen means that the device will inevitably last longer than equivalent Android devices.
"Yota certainly has a new approach to smartphones and they not only are trying to look different but to solve an issue many consumers have when it comes to managing battery life and constant notifications," said Carolina Milanesi, research vice president at Gartner.
"The big question will be how much consumers are prepared to pay for that different approach and how much they will bet on a new name."
