Hector Martin has analyzed the software update of the Pixel 4a. He determined that the battery profiles had changed such that "LSN" batteries (e.g. "Lishen"?) have a significantly lower charge limit.<ref>https://social.treehouse.systems/@marcan/113914172433692339</ref> Presumably this means that battery replacements will only restore battery performance if the battery is replaced with an "ATL" battery ("Amperex Technology Limited"). | |||
