Very disappointed with my BV 9000.
Just lasts 1 day and that with power saver.
My previous model was BV6800 and I just upgraded because the speaker was crab.
Anything I can do with the
For the battery, have you allowed few charging cicles to complete?
I have a brand new BV9000 and it started lasting one day, and now I get 40/48 hours lasting charge with wifi always on, lots of news reading and WhatsApp messages, audio and video.
My rule is never let battery go under 15% and remove from charge when it's full (no charging overnight).
Also, this is a 4180mh battery, meaning is big but not huge, I am pretty satisfied with it and with phone overall.
p. s. I was trying to upload screenshots of battery duration but it seems I am not allowed, maybe it's because it is my first post?
