operating time?

[n3rDy]

I am considering to buy the PineTab as my iPad from 2014 is growing very outdated (Shame on Apple for not providing updates & sending devices to trash.).

At this moment, I am a bit scared away by the reports on that bad power management:
"big downside is the missing battery management. The battery drain is huge - unfortunately also in standby mode."

Could anyone who owns a PineTab describe their experience w.r.t. power management & battery drain?
How long can you surf the web without need to recharge?
How many days with occasional sofa surfing dies it sustain before running out of energy?

Thanks in advance.

That link is for the PinePhone not the PineTab.
