iPhone 12 battery drains fast overnight
I bought the iPhone 12 a few days ago and didn’t have any problems. But last night the battery drained about 30% overnight, while not using my phone. It’s the first night it drained so fast.
I have installed iOs 14.4 at the moment. I’ve read this is probably a software problem which started months ago. Are they busy on fixing it? Or could this be another problem to my phone?
Is there a way I can fix this myself?
iPhone 12, iOS 14
