iPhone 14 Plus contact search slow and frequent shutdowns after iOS 27.1 update

Slow Contact Search and Names Not Displaying After Updating to iOS 27 / 27.1 on iPhone 14 Plus.

my iPhone was having issue of frequent shut down.. I complaint and call center informed me battery is week. battery was changed at apple authorised service center - I PLANET and I paid INR 15000 for battery and AMC on 12.10.2026 and there after phone was working well. later updated apple iOS 27.1 and software and Since updating, I have been experiencing significant issues with contact search and phone frequently switching off.

The search function has become very slow, and sometimes contact names do not appear even when I search for them. This issue occurs intermittently, and I have to repeatedly close and reopen the app to make the contact search work properly and phone frequently switch off.

after battery change and before the software update, I did not experience this problem.

My Questions:

  1. Is this issue caused by the recent iOS update, or is it a software bug?
  2. Is anyone else experiencing the same problem on their iPhone?
  3. Is there any reliable solution or workaround to fix this issue?

I request Apple to investigate this issue and release a fix as soon as possible, as contact searching is a basic and essential smartphone function.

Thank you for your support.
