I recently bought an Onyx Nova 3 tablet. I am surprised by the low battery duration. A full charge has never lasted more than 2 days (wifi off, lights moderately on), mostly for reading epub and pdf files. What surprised me was the sleep mode seemed to not stop the energy draining. It also drained energy when powered off.

I recently measured the discharge rate of the tablet in sleep mode, with wifi off, lights off, ungoogled. The device was fully charged, and I took measurements of the battery status at several moments since it was turned on. The device was always in sleep mode, only waking it up to register the battery status and the time.

I found that the device, only in sleep mode, was draining at a rate of 1% each 38 minutes, and the full charge lasted no more than 63 hours (for those interested, the results of the measurement can be found in the following link: https://docs.google.com/spreadsheets...it?usp=sharing )

Do you know if this is the normal behavior for a device whose battery is supposed to last for days in use? Has anyone else experienced something like this?
