Get the battery replaced, because you probably need one, and do a Backup and Restore. Should fix all the issues. I had the X for 5 years and it works perfectly fine. I just upgraded because I wanted a new phone.
If you don’t reinstall all the apps from backup it’s even better as you end up installing so many apps and barely use them.
@Onse @Gingerlegs I got my 12 three-ish years ago and I’m having a lot of stuttering issues now. Sometimes I don’t get notifications either.
Had the same problem with my phone before that. Had it for three years and then started having issues.
Notifications issues have existed for a long time in the iOS ecosystem. I have found that doing a full reset of the phone will resolve the issue.
(yes, I have reported the issue to Apple via Feedback but they just don’t care. Quality control has take a backseat)
