^ Yeah.
Your laptop is locked to an AMD processor. You can't upgrade without changing the motherboard and RAM and chipsets, and motherboards differ with models. You need a new laptop or PC.
The Dell G3 is a great choice, but there are other systems too:

i7 is a computer chip. I think you mean iPhone 7.
If the MP3 player has bluetooth, it may be possible, but I recall that bluetooth for the iPhone is only for the iPhone to play music on other devices.
While the Zenbook does look bad, it has some of the best specs.

Laptops are usually not upgradeable. Some laptops allow RAM upgrades, but afaik, that laptop does not allow upgrades as it it all soldered onto the board.

Within that budget, those are the balance in specs you can get.
There are other options but they have a weaker GPU and CPU in some cases. There are some laptops with an i7 but a GTX 1050Ti or so.

If you can take this you should be good:
