I just got a BBPB 64GB,but I found out the battery has to charge everyday even on the standby mode. Is it normal for the PB?

Not in my experience. In stand-by mode it can take nearly two days to discharge (24hrs). Even with heavy and continuous usage - wifi, games etc - I get a comfortable 8-10 hours. Its been great from that point of view. Think you may have a faulty battery.

what OS are you running?

do you have anything running?

i leave my wifi on and putin standby and get 50% battery left even after 48 hours.

I just got this new one ,nothing more than the original set-up(the newest OS).

I checked again and would agree with the above. I am on the most up-to-date OS version

Are you working fine or still need help?

if not ok, have you restarted your playbook?

I did many times restarting,but battery still not as strong as" friendshiptca" said.I will wait for a while to see if it can be improved.Thanks.
