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"). | Hector Martin has analyzed the software update of the Pixel 4a.

It is possible to differentiate between the manufactures by looking at the serial number on the battery. 8230015901 is ATL and 8230020501 is LSN. | ||
