This has happened to me before update and is still happening. Randomly. Maybe once per month, but it still meant I had to keep the backup device on me.
And I think I know why. I don't turn off my device after reading. Look here:

under T68. It says:

Important! Turn off your BOOX when you are not using it. Stand-by mode does not improve battery lasting.

So basically if you want 8 weeks of battery life with 30 minutes of reading daily it means you have to keep your device off 98% of the time. Or if you just want to be sure that device won't be empty after few hours. Other readers advertising 8 weeks of battery life can be in sleep mode during 98% of their time.
There is a setting(default on) in T68 that will turn the device off automatically after use. But that still means you have to boot the device, then enter the app that you want to use each time you want to use the device.
I've been looking for a way to get the device running without need to turn it off and without risk of it being empty after just few hours here, in my threat... And after weeks of trying everything I'm pretty confident that turning off the device is the only way to get reliable battery life. I've been monitoring the battery usage using many apks and nothing notices anything suspicious, so the device just has very poor energy management.
