My device is just 2 days of use. This bv7000 pro has bad battery management. I need around 4 hours to get it full, and I don't know why they called it is fast charging. The battery also is draining so fast where my mobile won't stay more than 7.5 hours of regular use of whatsapp and browser and some youtube.
I bought it because of the fast charging while I see a bad avery very slow charging. Now after I bought my device online from Joybuy shopping website I won't buy any chinese mobile online
The battery life can be related to how you use your phone, what app and how many apps are running on your phone.
