Chosen Solution
I recently replaced the battery in my iPhone 6 s plus. Thank you Ifixit. CPUdasher x reports the battery is fine, but iOS 11.3 beta 2 reports it needs to be replaced at 64% of capacity. Do you know why this discrepancy? The battery is only about a month old. Thanx, roncbee
did you calibrate it? at the bottom of the battery replacement guide it says: “To reassemble your device, follow these instructions in reverse order. For optimal performance, calibrate your newly installed battery: Drain battery below 10%, then charge uninterrupted to 100%.” iPhone 6s Plus Battery Replacement
