I have an iPhone SE. I wanted to get a new battery. I made the mistake of taking it to a non-Apple vendor. They broke my iPhone and I wonder what role the battery strips (missing from my iPhone) play.
The phone starts and I can log in. Everything is fine until the phone suddenly cuts out and goes dead. This happens both when charging and not charging. It doesn't shut down, just cuts out.
The shop staff told me it's a software issue. I just don't believe them as I don't see any process happening when it cuts and the state of the phone when it's back up is different from when it gets cut out.
The shop staff also lied to me about what was and wasn't in my phone when they returned it. Apple told me the battery strips were missing and the device should be replaced (I took it to Apple after the other vendor broke the phone).
So now I'm wondering what the significance and purpose of battery strips is? And, whether or not getting new strips might fix my phone?
Edit: I forgot to mention that I requested my original battery be put back in. So this cutting out problem happened with the replacement battery as well as with the original battery after their tampering.
