Night activity peaks with Exposure Notification - ITA

Hello! I bought an iPhone 11 in august and I was really happy that I could recharge it every other day. All of a sudden, more or less a week or two ago, I noticed some apparently random huge battery drains. I checked in Settings>Battery and between 00.00 and 09.00 there was like this strange 100% Exposure Notification peaks, 1h screen off activity. It doesn't happen every night but I can't identify for sure what changes the situation. I'm starting to think that it only happens when Wi-Fi is off until next morning, but for now it could be only a coincidence. What could it be? If it can be somehow useful, i'm in Italy and I have Immuni on my phone (but, to be clear, in these peaks this app never pops up, not even for a 1%). I'll update this with a screenshot as fast as I can!

Hello CirithThalion,


Thanks for taking the time to reach out here in Apple Support Communities. Based on your post it sounds like you've noticed that your battery life is shorter than expected. Is that right? We'll be happy to help advise. 


Are all your apps fully updated in the App Store?

If you're not certain, the article below will help you check. 


Update apps or use automatic downloads


Are you running the latest version of iOS 14.1? Keeping your iOS version up to date can help improve device performance as well. We would recommend creating a backup and updating your version of iOS if you have an update available.


Take a look at the articles listed below. Please keep in mind after you update there are many processes happening in the background that can cause battery life to be shorter than expected. If you continue to run into issues after a day or so you can reach out to Apple Support directly.
