No, I don’t think upgrading will help. I do not have the first issue you’ve mentioned but I am experiencing the second and third on my upgraded rk3588 pocket reform. The keyboard firmware is a bit unstable (I’m on the same version) and causes, I think, both problems. Sometimes I need to do a hard reset by toggling the power switch because the keyboard system is stuck; the keyboard works but the battery status is stuck on 0% and gives no indication of the power plug being connected (normally the -1 something amperes woobles a bit which i think is normal and seems to indicate it is charging) and the os reports 6% (coincidence?).
Using a powerbank when going cordless helps and I’ve ordered the batteries as mentioned in Getting more than 10 hours of battery runtime from the RK3588 Pocket Reform - #19 by UnlikelyLass to see if that would help because my guess is that the batteries are “lazy” and I hope these new ones are not..
