Yeah, we're all waiting at this point:)
I think it's done for bro. Maybe look for a pre-loved one?

I think you can buy a 2nd hand or a refurb one for cheaper

Maybe can try doing a restore/ DFU restore via iTunes, who knows it’s a software glitch
Considering that a brand new iPhone 8 starting price is rm2199 or wait for the new iPhone(with no headphone jack)

I'm having the same problem with an old iphone 6s plus, which previously had a black screen, unable to turn on, so I decided to send it to repair last week after sitting inside my drawer for two years, took them 3 days to fix the freaking screen, they told me that the phone backlight was out , had to replace 6 sticks of it, and needed to change some IC to make it working, they also replaced my camera, which i didn't know it had problems before, but nonetheless ok la not very expensive. cost me about rm400 to fix the backlight ,screen and camera, still worth it la i thought for a 6s plus kan.

But then, when i tried charging the phone after collecting the phone from the shop,  the phone gets very hot and the battery gets depleted like super fast, one minute it's 100% the next minute 91%. but the battery health is showing 82% health in the battery settings.

Does yours do the same too?
