HealthKit data is not available while the device is locked. You can start your HKObserverQuery while locked, but you will not receive callbacks and, if you are using background delivery, your app will not be launched for new data until the device unlocks and the Health database is available.

神奇，我的 iPhone 14 Pro 曾经遇到了极为相似的问题

Issue:
- Customer reports device overheats when using both wired and MagSafe charging
- device also has cellular connectivity issues, where it will appear as ‘Searching’
- customer reports cellular issue occurs after device starts overheating, on charge, and being used for personal hotspot
- issue occurs with both eSim and physical SIM card

Steps to Reproduce:
- ran Mobile resource inspector passed, software is up to date
- ran cellular rf test passed
- ran cellular voice and results show issue could be caused by network issues with carrier, or low cellular coverage in environment, 14 day summary shows 1% not in service
- issue was reproduced in store after device was put on charge, using 5G, personal hotspot activated, customer was taking photos, and ‘No Service’ came up for 5 minutes, following that the device switched to 4G and after a minute it switched to 5G

- performed restore on device and set up as new. Tested out same conditions, with phone being on charge, with customer’s e-sim using personal hotspot, taking photos with device. Tested out with known good SIM card with same conditions, and issue persists with the same pattern

Cosmetic Condition:
- display has screen protector no notable damage
- rear no notable damage
- Liquid contact indicator not triggered
- security screws intact
- front camera no notable damage
- rear camera no notable damage

Proposed Resolution:
- proposed to do rear system repair on device at no cost covered by warranty
- customer has backup through iCloud and will reactive his eSim if needed

用 iPad 当唯一显示器是可行的，需要一个 usb-c 口的采集卡 + hdmi 线 + 相关 app (比如 Orion). 比真正的显示器有一定延迟，但比 sidecar 要流畅稳定。

@julyclyde 还好，光标放在 mute 按钮上，用中控台的实体按钮来 mute / unmute, 完全不需要看屏幕
