iPhone 12 Pro Severe Battery Drain

Do you have a heating problem too? My iphone 12 pro got heated up pretty frequently. I guess it's to do with the battery as well.

Yes same issue. It’s not indexing or anything. I can’t even go a full work day without charging. I think there is something wrong.

Hello, no I'm not experiencing the heating problem.

What was the outcome of your call? I am having the same issue. 12pro, all apps closed off, background app refresh disabled, went from 97% to 55% while idle overnight.

My phone is on wifi all day and the drain is still significant, averaging 10% an hour just sitting on my desk

Ridiculous. I asked Apple support and they just told me to use my phone less. considering the design is similar to iPhone 4 I guess they also adapted the “holding it wrong” strategy.

iOS 14.3 is the last hope for many to resolve this issue, let’s wait and see.

IOS 14.2.1 just showed up. Wonder if it addresses the issue

14.2.1 has been a 45-60 min less hit for me.

It’s seems to be ok in 4 days in my case. Had to disable esim with addition plan though and now scared to enable it back.

I have the same problem with the phone, I wonder how soon Apple is going to address this issue.

With time it changes ? Because It’s draining too much

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.

It's going to be an issue for a while as only data is sent over 5G, phone calls are sent via the LTE network so the phone needs to constantly jump between both.

Also, connection to the cell tower will drain the battery if your signal level is low (one to two bars.)
