Are you listening to yourself?
Put the pipe down dude.
Right? its just waffle.
Mods are mods are mods. This thread is a catastrophe.
Sorry OP that somebody at apple on the phone said your modified iPhone with a third party battery was fine on trade in, sadly it wasn't, and that's caused you some upset. that's completely understandable.
But Apple and the trade in company they work with is right to reduce the value of the product if it's been modified in any way, and their terms on the site speculate that in two different areas. Such as "Why did I receive a revised trade-in value offer?
If the condition of your device is different from what you described, we’ll provide a revised value."
and
"Trade‑in values will vary based on the condition, year, and configuration of your eligible trade‑in device. Not all devices are eligible for credit."
Changing the battery in a portable device
does mean its different from stock. Ergo its modified.
That's the crux here; a portable device with a third party battery is also a potential safety risk as there's never ever going to be a guarantee that a non-Apple battery will fail or react or even act in the same way that Apple batteries do. (in my experience, third party batteries I've handled are either
reprogrammed-used batteries, or laughably smaller in chemistry, ie.rated 1800Mah but clearly performing like its 850mah) Third party camera's and displays are even worse, i've seen LCD displays on devices that should have OLEDS.. these things ultimately LOWER THE VALUE OF THE DEVICE.
OP, It's also a shame that this meant you gave back your iPhone 15.
Anyways. the other folk in this thread are performing Olympic gold mental gymnastics just to skirt around and increase their post count.
There is a lesson to be had here, if you wish to have you iPhone serviced AND retain its full trade in value please have your iPhone serviced by a qualified technician and only install genuine components, like... at the
Apple Store for example. then you know you'll never have this happen again. And if you read this, and scoff at how "it's overpriced" or whatever, remember this is a discussion about money already. Trade in values and all that. quelle surpris.
