G_sagun_rana_cqnM, Apr 21, 2017 : I kept the wifi on over night and i lost 30% of battery. Android system is not consuming battery much. Just 3hrs of screen on time. not even on heavy usage. always on wifi and brightness below 50%. Just fedup with the battery backup. Never gonna buy oneplus again. Dash charge is just makeup over poor battery. I'll rather buy device that last long which even don't come with fast charge.
