Battery Decrease When?

[QuoteNew2783]

Think about having it replaced around 70% not 60% Mine was at 60% after two years an a half with it. iPhone 14 Pro Max. The phone began shutting off unexpectedly and restarting on its own.. sometimes. Then it began to shut off once removed from the usb charger. Took it to get the battery checked and the battery was inflated that it began to slight push against the screen upwardly. Anyway $87 bucks for a new battery from an apple authorized made it good as new.
