Boyue T63S battery

[solnce]

Hi guys

I wonder if anyone could help me regards Boyue T63S battery time. I purchased new device week ago and for me it seems to little to have just 5 days for the screen on time. It is quite a lot for mobile phone, but from ebook device I would expect much more.
If I turn on Auto Off mode after 20 min of sleep, it lasts much longer, but then I need to turn it on and it takes 20-30 seconds to load. So it is not convenient - to keep it sleeping for five days or to turn on/off every 20 minutes.

Then I did factory reset and things went even worse - 20 hours screen on time and battery drains 10% every hour (no lights and wifi on).

I suspect I got defective device. What do you think? May be I am doing something wrong? What should be a sleeping screen on time?



Can post screen shots if needed.

Thank you.
