The battery issue is getting ridicules, a main aspect I considered as a consumer to buy this phone was the massive 4000mAh battery, which on other phones provides 1.5 - 2 days without the need of charging.

With the M5 Note latest version we get 12 hours Max

This should be the first priority on Flyme todo list because the majority of the m5 Note holder will simply never going to buy/recommend Meizu phones again.
