iPhone 14 Battery Draining after update

Factory Reset worked for me. That's what Apple does when replacing internal components. The technicon has to do a full backup before working on your phone. After replacing the camera module a factory reset was done followed by the restore.

The camera module may not have been the cause of battery drain.

If I was you I’d take it to Apple and explain especially if it’s a 14 pro max they’ll do a test and see if it’s camera module that fails

Reset works.

Do a full backup to iCloud first.

Don't erase the eSIM because it has all of your Carrier information.

Did Genius Bar say whether camera module was causing drain while phone’s in use vs only in sleep mode (overnight)? I’m assuming the former but maybe optimized charging feature is a factor?

From reading various threads on battery drain since 16.5, the 2 root causes appear to be camera module issue & iMessages constantly running in background. Anyone aware of others? I’ve resorted to keeping phone in low battery mode all day (doesn’t help much) & turning phone off at night after it reaches 100% to ensure I have full charge in a.m.

Has anyone come up w/a theory as to why not all iPhones are affected? Could stainless steel vs aluminum frame be a factor? Wouldn’t think so but trying to ID diffs since friends & family w/aluminum 13 pros don’t have battery drain probs while I do & mine is stainless.

Same problem. I noticed that Wallet has the highest battery usage by app, constantly over 71%. Strange!

Updating my post: Reset worked on my 14 Pro Max with IOS 16.5.1

Reset doesn't work in all cases.

Since the update it uses all its power for background activities especially when no telephone reception but also Podcasts, etc. Before no problem whatsoever!

Another nuisance, my AirPods Pro do not reconnect automatically again after losing connection for a short while.

My 13 pro max (1.5 yrs iold) is now down to 88% battery health. Since Apple recommends replacing battery when it’s below 80%, I only have 8% battery life left. The bal due on cost of this iPhone will outlive its health. Not a good look Apple.

On average, a battery will lose capacity at approximately 1% a month. So, you are seeing performance within expected parameters. Batteries are consumables.

I have visited Apple twice regarding the battery issue with my iPhone 14 Pro. The first time, they suggested that the problem might be with my charger and recommended I buy a 20W block. I followed their advice and purchased the new charger, but it didn't improve the battery life.

Feeling frustrated, I went to a different Apple location a few days later, and they thought it could be a software-related problem. They had me perform a hard reset on my phone and set it up as new, hoping it would resolve the issue. However, even after trying this, the battery continues to drain rapidly. In just under 5 minutes, my phone's battery goes down by 3%.

I requested a battery replacement, but Apple refused, claiming that my battery health is still at 100%. Nonetheless, I am convinced that the battery is faulty, especially because I never encountered such problems with any of the 12 iPhones I owned in the past.

I'm unsure of what to do next, as I've exhausted the troubleshooting steps suggested by Apple. I want to find a solution to this battery drain problem as soon as possible.

Same problem with me

Same problem here

Same solutions. There are no other options.

Help me

My iPhone 14 pro max is drain battery after update to iOS 16.3.1

The update was performed on February 21. I have serious doubts that time will solve this issue!
