I’m a moderately heavy user. I find I have to replace the battery every three years or so. Right now, mine is down to 70%. One of my gripes is that the replacement batteries are not as good as OEM, even when I buy from iFixit. So, I guess I’ll spend $80 and waste the better part of a day (which is the worst part), even though I’ve replaced several iPhone batteries and have all the tools.
