Ok ive isolated my problem. It was Contacts iCloud syncing constantly. I switched off the toggle in iCloud and location services are back to normal and battery on 16.1.2 is sweet now.

God knows how and why they are related to each other.

If someone with similar problem wants to check it out for me on Beta 4 please :D

Contacts Battery Drain

There's a long discussion about this issue. Apple seems to only be acknowledging the problem now.
 
Can anyone try to use the following two buttons on a notification from the lockscreen when your album cover is set to full screen? These buttons have not been working since iOS 16 has been released and still not fixed on the latest final release. I don't know how to provide bug related feedback without the feedback app (I am not on the beta)

As it says on the first post in this thread, open safari and paste: "applefeedback://". It will open the feedback app. It's always there, but hidden on releases and release candidates. If you don't like that, you can type from anywhere: "https://feedbackassistant.apple.com/".

Seems to have worked for me too.
Unfortuantely I need Contacts syncing to iCloud because my organization uses Intune. It's the only way I get contacts at all is having Outlook export them and then it syncs to iCloud for my iPad and mac. Turning it off is not a solution.
 
Find my iPhone, Motion Calibration & Distance, Networking & Wirleless and Satellite Connection are the culprits on my device.
Hi, I’m having this problem since 16.2. I didn’t have this issue at all on 16.1.2. Is there any fix to this? I already erased my phone, iPad, MacBook and restored from iCloud backup but the issue hasn’t gone away. I was so close to start from scratch without restoring from a backup which I want to avoid. Do you think another update would fix this?

I had really noticeable battery drain for about a week after installing 16.2 and at first while I thought it might be the "system services" banner in the control center seemingly never disappearing but after looking a bit in my battery I saw that mail for whatever reason had a huge spike in terms of background activity despite being completely off. After deleting the app and rebooting my phone I can already tell a difference. I can only assume it was some bug in mail fr whatever reason but I will continue to monitor it going forward.
