Slow charging and battery percentage stuck on MacBook Pro M2 after macOS Tahoe update

Updated to mac os tahoe 26.0.1 to my m2 pro 13 inch , and noticed battery is stuck at 21% , connected adapter and coconutBattery software shows charging going slow to battery , my cycle count is 147, battery health 93, condition: normal , but if i do apple diagnostic it is battery service required , Mostly this is due to this buggy tahoe that did this. Anyone else facing this issue? Didn’t tried reinstalling Os yet

Update: I connected on my adapter intially slowly charged with 7-8 W and eventually went highest till 35W , amd i charge upto95. Whatever i checked through apple logs and all battery information, chatgpt replied there is no permanent failure , and indicating either the BMS is limiting charge to resync battery or a software glitch. Anyways already tried restart also. i also suspect tgis just Battery management doing its job to resync thats why slowly charging, very slow , need couple of days to test tahoe 26.0.1 if issue still persists

Presume you've shut down and rebooted your Mac and the problem persists?

Have not run across this previously. If convenient, I suggest s visit to the Genius Bar.
