EV batteries cost $5000+ to replace and are expected to last 7-10 years, maybe more if you push it. And they are a huge pain to recharge in the middle of the day if you suddenly need to. How many years do you plan to keep your phone for? Who cares if the battery only has 70% of original capacity after 3 years and on some days you need to find 20minutess in the middle of the day to leave it plugged in to recharge?
