Hello, a few weeks ago I received my BV9800 pro, I have a question ... How long does a full battery charge last?

To me it is lasting around 24 hours, I think that my use is moderate and I am not very satisfied according to what the advertising of blackview promises. 

Everything else is perfect so far.

Normal usage battery last for about 36 hours check if you have the GPS on all the time that drains the battery...

When I use the phone seriously, the battery lasts 2-3 days. At the most serious load I have achieved - 2 days. When I have a lot of work, and I do not have time to use it seriously, it lasts up to 10 days. In fact, the battery is one of the things I enjoy most about this phone

What version of android does your cell phone have? 
I have carried out different tests to find the problem, when I went to sleep the phone had 91% battery, I left it in airplane mode and after 6 hours without using it I had 70%, check the history of use of the battery but it does not record any application. I use Greenify app to keep apps sleeping. Also disable all smart assistant functions. I have always used only the original charger.

How long does it take for your phones to charge from 20% to 100%?

I had the same problem after the phone installed it's latest firmware, tracked it down to the Google play services consuming up to 20% of battery power per day. I went to APK mirror and installed the latest Google play services APK, and now it is down to 4-5% per day for the updated app. Hope this helps.

The device has the firmware with which I bought it in early February. I dare not update it, although it constantly reminds me, precisely because everything works perfectly and I'm afraid there will be problems. The cable is charged in about 2 - 2.5 hours, and the battery heats up. To keep the rubber seal on the usb connector, I bought a wireless charger in the beginning. With it, charging from 20 percent to 100 takes about 12 hours, but the battery lasts significantly longer. This morning I picked it up from the charging station, it was 100%, now at the end of the day it is 96%, but I had almost no time to use it. Greetings!
