If your iPhone personal hotspot feels slow or restricted, Low Data Mode is the likely culprit. This feature, available since iOS 13, can be active in two places: on the host iPhone's cellular connection or on the device connected to your hotspot, each limiting your speed in different ways.
Is hotspot low data mode slowing you down?
Low Data Mode is designed to reduce network data usage by restricting background activity like automatic updates, app downloads, and iCloud syncing. It also lowers the quality of streaming content and optimizes FaceTime video bitrate for lower bandwidth. When this mode is active on your hotspot connection, it directly throttles the speed available to every device you share your connection with, making it the most common reason for a slow personal hotspot.
Fix 1: Turn off low data mode on your iPhone's cellular connection
This is the most direct fix for the host device. The steps differ depending on whether your iPhone uses 4G/LTE or 5G.
- Open Settings and tap Cellular.
- Tap Cellular Data Options.
- For LTE/4G iPhones: Toggle Low Data Mode off.
For 5G iPhones: Tap Data Mode, then choose Standard or Allow More Data on 5G instead of Low Data Mode.
Once you disable it here, your hotspot will stop restricting background data and streaming quality for all connected devices.
Fix 2: Turn off low data mode on the connected device
If your host iPhone's cellular data is already set to Standard or Allow More Data, the slowdown may be coming from the device connected to your hotspot. Each connected device can independently enable Low Data Mode on the Wi-Fi network it's using. Low Data Mode can be enabled on other devices like tablets, laptops, and smart TVs to manage data consumption.
- On the connected device (laptop, tablet, or other phone), go to Settings and tap Wi-Fi.
- Tap the Info button (ⓘ) next to your iPhone's hotspot network name.
- Toggle Low Data Mode off.
This removes the restriction on that specific device, allowing it to use full hotspot speed for streaming, downloads, and background tasks.
Why does my hotspot seem to be in low data mode automatically?
Low Data Mode does not turn on by itself. It is a manual setting that must be enabled in either the host iPhone's cellular data options or the connected device's Wi-Fi settings. If your hotspot appears to be in Low Data Mode without you remembering turning it on, you likely enabled it previously and forgot, or it was set up intentionally to save data. This is especially common when managing cellular data settings and fixing issues after traveling abroad or using a limited data plan. Some hotspot devices offer the option to prioritize certain applications or devices when Low Data Mode is enabled. Some users also enable it to help stop iPhone personal hotspot from turning off automatically, since reducing background data can extend the hotspot session. To restore full speed, check both locations described in the fixes above.
Frequently Asked Questions
Will turning off Low Data Mode use more of my cellular data?
Yes. Disabling Low Data Mode allows apps to refresh in the background, download updates, and stream at higher quality, which increases data consumption. If you have a limited plan, consider re-enabling it when not using the hotspot.
Does Low Data Mode affect battery life on my iPhone?
It can help conserve battery because it reduces network activity and background tasks. However, the effect is modest compared to other battery-saving measures like lowering screen brightness or disabling unnecessary radios.
Can I use Low Data Mode on only some connected devices?
Yes. You can leave Low Data Mode enabled on the host iPhone's cellular connection to save data overall, then disable it individually on specific connected devices that need full speed for streaming or downloads.
Can I customize Low Data Mode settings on my hotspot?
No, Low Data Mode is a system-wide toggle without granular controls. You cannot adjust specific parameters like background app refresh or system updates individually; it applies a blanket restriction to all non-essential network activity.
Why is my hotspot still slow after turning off Low Data Mode?
Other factors can slow a hotspot, including weak cellular signal, network congestion, or data caps imposed by your carrier. Check your signal strength and consider moving to a better location, or contact your carrier about hotspot data allowances and plans.
