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.

  • A photo might help to explain what a battery strip is. But honestly I think the non-Apple vendor just broke your phone and you should take it up with them to have it fixed. – nohillside Jun 25 at 7:06
  • A battery strip is better Googled I suppose... I can't take a photo because I can't get inside the phone and my phone apparently doesn't even have one anymore! – Dee Jun 25 at 7:46
  • According to what I found online, it's basically a pair of sticky strips stuck on to the battery and serves some purpose to do with static. – Dee Jun 25 at 7:47
  • It‘s a bit unclear what kind of answer you expect from us here. Analyzing hardware issues introduced by a careless service technician is nearly impossible without access to the device. – nohillside Jun 25 at 9:38

Battery strips are adhesive, stretchy "tape" strips. The purpose of them is to keep the battery in place, as well as slightly insulate the battery from the casing. The insulation means that sudden applications of heat or cold to the outside case (such as for example taking the phone out in intense sun light, or placing it on a very cold surface) doesn't immediately transfer the heat/cold to the battery via the aluminium casing.

If you're not exposing the phone to these changes in heat/cold when the cutout happens, it just sounds like you've received a non-Apple battery replacement of low quality.

Usually these cuts outs happen when the phone hardware uses more power than the battery can provide. As the power draw increases, the current (i.e. volts) are lowered slightly. With a bad battery, a normal power usage can lower the current so significantly that it is below the requirements of the CPU. This means that the system just shuts off immediately.

It is obviously not healthy for a phone.

I see it as very unlikely that new battery strips will solve your problem, unless you specifically see the problem when shaking the phone, or exposing it to heat/cold. Your problem could potentially be solved by replacing the battery - but then you'll also want battery strips installed ofcourse.

  • This is interesting, thank you. I will have to update my question as I seem to have left out a detail - I requested my original battery be replaced and they said they had done so. Apple also didn't report that the battery was different. So it's the original battery... Perhaps they broke something else? – Dee Jun 25 at 9:28
  • You are not really making sense to me now. You had a phone with a battery. You wanted the battery replaced. Why did you want it replaced? - Now you're saying it is the original battery in there - did you swap it back again after you discovered the problem? – jksoegaard Jun 25 at 12:44
  • Yes I swapped it back after I discovered the problem. So I originally wanted the battery replaced as it had started to get old and would not last a day anymore. – Dee Jun 26 at 17:01
  • Did you swap it back yourself? Then it’s hard to go back and complain to the shop I guess. You might have broken even more things that way. Did you use a guide? Which one? – jksoegaard Jun 26 at 19:13
  • I didn't swap it back myself. When I saw the first replacement wasn't working pretty immediately I requested they keep my original battery aside in case I wanted it back in. Eventually I told them to put my original back in. I never made any change to the phone myself. I wouldn't have a clue. – Dee Jun 27 at 21:20
