Maybe the EV batteries work like my tablet battery: your battery lasts less time every time you recharge. My tablet is maybe 3 years old. I’ve been using it for 2 hours, and battery is 79% charged. Last week it was usually around 57% charged when I went to sleep & recharged. Yesterday, using less online time, it was 17% charged.
