The Moondrop MIAD 01 is one of the most distinctive Android devices of 2024 thus far. It has a 4.4mm headphone jack to go with the more conventional 3.5mm type. Furthermore, it seems it might be as appealing to teardown enthusiasts as well as audiophiles, and may, therefore, also be easier to repair than most modern smartphones.
Just look at the inside any modern smartphone, it’s full of battery and other stuff, basically no empty space. The iPhone 7 was the first generation without a headphone jack, it still used the old case design though. Look at the iPhone X which was completely redesigned, it’s just marginally larger than the iPhone 6/6s/7/8 (they all use the same case design) but has a much larger battery. They went from 7.45Wh (1960mAh) on the iPhone 7
to 10.35Wh (2716mAh) on the iPhone X.
I feel like the bottom phone there looks more empty than the top, it looks like there is still some room at the top and bottom there.
But anyhow, they’ve removed the headphone jacks from iPads as well and those certainly have some room left
No. Most of the iPad lineup uses LCD displays which are relatively thick. The headphone jack only fits in old iPads, because of the large bezels. On newer iPads, the headphone jack would need to go under the display, making the entire device much thicker. With OLED, you don’t have this problem, but Apple either uses LCD or Mini-LED for iPads.
