Didn't notice any issues with connection speed/stability.
> iPhone 17e also features C1X, the latest-generation cellular modem designed by Apple
But the 17e iPhone seems to lack the Apple developed N1 chip that provides Wifi 7 + Bluetooth 6. So presumably they're using off the shelf components for Wifi and Bluetooth in the 17e.
For example, the 16e has the C1 modem but the standard Broadcom (or whoever) Wi-Fi and Bluetooth chipset.
I couldn't care less about multi-gigabit 5G speeds (my 15 Pro can already practically get ~2 Gbps – who really needs that in a battery-powered phone?!); give me better battery life (my 15 Pro gets warm to the touch doing absolutely nothing in some 5G scenarios) and better security (e.g. carrier-side location tracking prevention) any day.
