I have my iPhone configured to act as a hotspot, providing internet access via cell data.
When connecting my iPad as a WiFi client to that hotspot, the Settings panel notes “Low Data Mode” below the name of the connected hotspot. Indeed, while using the iPad, the internet connection seems much slower than on the iPhone.
My carrier, T-Mobile, does limit the amount of fast data delivered via “tethering”. Is this “Low Data Mode” note a sign of that limit being reached?
I have never not seen that subtitle, so I am left uncertain.

According to this source Apple introduced a new feature to reduce and limit cellular and Wi-Fi usage. This feature is called Low Data Mode. You can use this feature on your iPhone, iPad or iPod touch to limit the mobile data used in background mode by apps.
See Apple support page, Use Low Data Mode on iPhone, iPad, and iPod touch.
Please note that Low Data Mode is automatically enabled when you are connected to a Personal Hotspot.
