Re: Note 20 ultra battery not improved after October update.
the only way battery life would be improved by updating thru the software would be in the detailed updated description they give you in the update layout. samsung would say something like performance and security issues has been updated. and battery life has been updated to expand longer and your device will now run cooler. I haven't seen an update where it said battery improvements has been made in a long time. I have Note 10+ and battery life is superior. its been superior for me in the note series lineup since the launch of the bigger battery capacity of the note 9. this is one of the reasons why I haven't upgraded to the note 20 ultra. the other reason is the storage. I like my 256gb of storage
