I’ll tell you right now your phone wont last a decade.

That battery, even with light usage, will eventually degrade to the point you’ll have to charge it multiple times a day to keep it alive.

and then you’ll have to do the math and decide between getting a new battery and just getting a new phone.

Thats the decision i had to make when I needed a battery for my old phone… Did the math and found the cost of a new (to me) used phone was close enough to the cost of the replacement battery + labor that it was more value to me getting the newer phone, with newer OS, and still in the receiving update window than putting a aftermarket battery in my old phone.
