Should I update iPhone to iOS 18 if it's been repaired by 3rd party?

Did you update yours? Cause i am scared to update to ios since i got my lcd replaced by a third party vendor too..

hi! any update about your phone? i haven’t update mine because i’m too scared that it might lock it 🥹

You trust anything from a site that promoted eating poisonous laundry detergent or committing check fraud?

You can see on YouTube and TikTok that the world is flat too. TikTok is hardly a reliable place to get iPhone information from. There is nothing which has been publicly published by ANY reputable sources that iOS 18 should not be installed on devices which have been serviced by third parties. The fact a device may have been serviced by anyone other than Apple of an Apple Authorized Service Provider, does make it ineligible for support for the device from Apple directly.

1: iOS 18 has not been released.

2: TikTok and similar apps are a wasteland of nonsense.

Yes you can update your iphone 11 even if your phone had a third party replacement.

How didd I know?

Because I’m using mine rn, and I did update it to ios 18 and there’s no problem, it ain’t even laggy

I got a used iPhone 12 from an online store, upon setup it said unknown display and battery.

This seemed to help me:

1. Updated to newly available iOS 18.0.1
2. Started phone in diagnostics mode
3. Clicked finish repair for the display (over wifi)
4. Message said the display was genuine part, so finished the repair
5. Battery was apparently not genuine part, but I think that is not so important as display
6. Restarted phone

The warning messages for unknown battery and display did not appear (yay)

Under repair history for the phone the display and battery are listed as unknown, but OK I think

Will it help you? Who knows

I have updated my to 18.1.1, I had my screen changed and battery from third party, and after the update my phone started to just turn off on 30% and when turning back on shows 1% and doesn’t charge. The phone accepted the screen replacement but the battery no. So better stay on your old update

Naah, it work fine

Hello please can I update my iPhone12pro to iOS 18 with an unknown screen part and battery at 77%

Updating your phone is the least of your worries. At 77% battery health, you're more pressing issue right now is having your battery replaced. The battery should have been replaced when battery health dipped to 80%. Whether Apple will be willing to replace the battery is unknown. They usually won't touch a phone which has been tampered with and your phone has an non-authentic screen.

iPhone 12 is certainly capable of running iOS 18. Your battery is your primary concern at this point. If you continue using the battery, it could swell and destroy your phone, which would require you to buy a new phone.

iOS 18 supports Activation Lock on iPhone parts. So I suppose it might not be a good idea to run iOS 18 if you know that someone has repaired your iPhone with parts from a stolen phone.

Hopefully you would pick a repair shop that would not engage in this kind of behavior.

Im scared to cause I buy my phone on 3rd party vendors and I dont know if my device have any repair history so I dont know what to do ahaha

Don't even think about doing this until you have first replaced the battery and the phone is working well.

Even then, Battery Health settings are not going to work correctly.....if they work at all.
