[ASMR] What? Is It Already Time to Replace the iPhone 16 Pro Max Battery?

Описание: This iPhone 16 Pro Max has been used by our follower for a year. With only 366 charge cycles, its battery health has dropped to 89%, and daily battery life failed to meet his expectations, so he sent it in for a high-capacity battery upgrade. The device still runs on iOS 18 and remains in good overall condition.
We cleaned the dusty bottom speaker mesh, installed a 5050mAh SeFu high-capacity cell paired with an original zero-cycle battery flex cable, reapplied the factory waterproof adhesive and pressurized the device to fully restore its airtightness.
In a real-world test with 50% brightness and volume, continuous live streaming playback lasted 11 hours and 22 minutes, delivering a noticeable improvement in overall battery endurance.
