I’m dead set in my belief that this happens to every phone, and I’m sad to see the nothing phone is going the same way.

I had a Motorola X that was suddenly dying in less than 5 hours and one day I couldn’t even connect to my service. I looked and found that an update had uninstalled the phone’s modem. Not even a factory reset helped.

After rooting and finding the correct package for my modern, the phone ran flawlessly using Resurrection Remix (I miss that ROM), proving that the battery and modem were indeed fine.
