MobileRead Forums - View Single Post - PocketBook Verse Pro – Battery drain while the device is sleeping (about 5% per day)

When I shutdown the device completely the battery last much longer indeed, but it takes quite few seconds (over 20 in total) to boot up and load a book (BTW, I noticed, that some books loads longer in KoReader - some loads almost instantly after boot up, but in case of others there is like additional progress bar which takes another few seconds). It's a downgrade compared to Kindle, where I could open the cover and start reading instantly and the battery was holding for many weeks.
In PB I have to open a cover, press and hold the power button, wait exactly 22 seconds (I just checked with a stopwatch). I could achieve the same as in Kindle here by simply locking the device, but with the cost for battery.
I wonder why PB drains so much battery when not used. I have Wifi and BT turned off.
Best regards.
