Only $50 less than buying brand new from Apple… it might be a better deal than what’s on Amazon currently but it’s still a bad deal overall. Why? The indicated minimum battery health of 85%.
When a battery reaches less than 80% capacity Apple officially considers it’s health to be “significantly degraded” meaning the phones performance will very likely be throttled. This can be disabled of course, but that can lead to unexpected reboots or other performance issues.
TL;DR - this isn’t worth the risk at this price; do yourself a favor and pay the extra $50 to get a brand new iPhone 11 from Apple directly.
