A smartphone with two screens - one of which uses e-ink technology and is "always on" - has been launched.
The Russian company Yota said the phone would go on sale online immediately in Russia, Austria, France, Spain and Germany.
The Android-powered phone promises to extend battery life by transferring web pages and other applications to the e-ink screen.
Experts said it may prove attractive to users fed up with drained batteries.
The phone has one LCD display, similar to those found on other smartphones, and a second e-ink screen which the company says lets users see the information they want without having to wake up the phone.
