Possible battery bulge with screen light spots

So for the background: I realized my battery was on its last legs around christmas. I bought a battery replacement kit from here on 1/6/2018 and the whole process was super smooth. My battery life was back to something respectable and no issues.

Until about a week ago.

I started to notice a light spot toward the top of my screen (i'll attach pictures). It started to grow and is now a 'band' of what appear to be LEDs. I noticed that early on they would disappear if pressure was applied around the case...making me feel like this was a physical problem. I then noticed that my battery life was significantly diminished...i mean dramatically. I was getting through most of the day on a single charge, but now i'm lucky if my phone is alive by the time i get off the train in the morning.

Now, a week later, the band of lights is incredibly noticeable and the screen appears to be bulging away from the case itself.

Is this simply a matter of getting a new battery? I am only 4 months into the ifixit replacement battery and despite my previous experience with the dead battery from Apple, i never saw anything like this.

EDIT: Also secondary question...if this battery is faulty and causing this sort of expansion, is it possible that my screen is permanently damaged?

For clarification have you ever replaced the LCD on your device?


I have not. The only repair that has ever been made or needed was the battery. The phone has lived a boring life with no water damage, drops, diseases, family struggles, etc.

It looks like the battery is expanding (ballooning) and exerting pressure on the screen assembly. That is a common symptom of a dead or dying battery. iFixit offers lifetime warranty on their batteries so contact support ( and work with them for a proper resolution.

Ok i've put in an email to them and hopefully this is the issue. Is there a way to mitigate the impact of this until i am able to replace the battery? I have actually upgraded to a new phone, but plan on keeping this one for as long as possible to use as a backup/business phone.


The risk is that as the battery continues to bulge, it may eventually damage the screen. I would open up the phone, disconnect the battery, remove it and if iFixit doesn't ask for it in return, dispose of it properly and securely.


ok solid. I will do exactly that. Thank you for all the support and hopefully i can resolve this before any permanent damage occurs.
