We recently reviewed the Meizu MX4 and concluded it has stellar battery performance so now it’s time to shed some more light on it.

The Meizu MX4 was able to squeeze 89 hours of endurance from its 3,100mAh battery – that’s the time you can go without a charge if you do an hour of calling, browsing and watching video on your phone. It did so by getting very impressive talk time and browsing results and a commendable video playback result. To wrap the 89 hour off stand-by was very impressive too. Read more »
