iPhone 12 Pro Severe Battery Drain

Anybody noticing severe battery drain for the iPhone 12 Pro right out of the box?


It makes sense that the battery drain is significant compared to the 11 Pro because of the smaller battery but you’d expect Apple would have worked on hardware and software optimization to improve battery life even with a smaller battery.

iPhone 12 Pro, iOS 14

Sorry, but that is not true. It is not the connection to the cell tower for phone calls and sms that is draining the battery. It’s the data traffic going through the cellular modem. This obviously doesn’t happen when using WiFi.


Either Way. The constant flipping between 5G and 4G seems to be fixed in the most recent 14.2 public version. Hopefully that improves battery drain.
