Quick Answer

If your Xiaomi hotspot keeps disconnecting, common causes include battery optimisation issues, carrier data limits, or too many connected devices. Start by disabling battery optimisation for system apps, checking whether hotspot drops only after the screen turns off, and reviewing your data allowance. These steps work the same across the UK.

Before You Start

  • Check your data allowance – Some UK carriers disconnect hotspot when you reach a data limit or fair usage policy threshold.
  • Check how many devices are connected – Most phones have a limit of 5-8 devices. Reducing the number may stabilise the connection.
  • Check your carrier's tethering policy – Some UK networks restrict or limit tethering on cheaper plans.

Why Xiaomi Hotspot Keeps Disconnecting

Understanding why this happens helps you fix it correctly:

Phone-Related Causes

  • Battery optimisation – A common cause, especially when the phone enters sleep mode. HyperOS power management may affect hotspot behaviour when the device enters sleep mode.
  • Data Saver enabled – Data Saver can restrict background data and cause disconnections.
  • Network settings corruption – System network settings may need to be reset.
  • Screen lock behaviour – Some Xiaomi devices disable hotspot when the screen locks. Check whether hotspot disconnects only after the screen turns off.
  • HyperOS updates – Major updates can sometimes reset network profiles or change power management behaviour.

Carrier-Related Causes

  • Data allowance exceeded – Some UK carriers disconnect hotspot when you reach a data limit.
  • Tethering restricted – Some UK networks restrict tethering on cheaper plans.
  • Network congestion – In busy areas, some carriers may prioritise other traffic over tethering.
  • Connection timeout – Some carriers automatically disconnect idle hotspot connections after a period of inactivity.

Quick Fixes (Start Here)

Step 1: Disable Battery Optimisation for Hotspot

HyperOS power management may affect hotspot behaviour when the device enters sleep mode. This is a common cause of disconnections, especially when the screen turns off.

  • Settings → Battery → Battery saver / App battery settings (menu names vary slightly by HyperOS version)
  • Set System apps to No restrictions
  • Restart your phone and test

Visual Path: Settings → Battery → Battery saver / App battery settings → System apps → No restrictions

Step 2: Check If Hotspot Drops When Screen Turns Off

Some Xiaomi devices disable hotspot when the screen locks. Check whether hotspot disconnects only after the screen turns off. If it does, review battery optimisation settings above.

  • Keep the screen on while tethering to test if the disconnections stop
  • If the issue stops, the cause is screen-lock power saving

Step 3: Disable Data Saver

Data Saver can restrict background data and cause disconnections.

  1. Settings → Mobile network
  2. Tap Data Saver (or Data usage → Data Saver)
  3. Turn it OFF
  4. Test the hotspot again

Visual Path: Settings → Mobile network → Data Saver → OFF

Step 4: Reduce the Number of Connected Devices

Most phones have a limit of 5-8 simultaneous hotspot connections. Exceeding this limit can cause disconnections.

  • Check how many devices are connected to your hotspot
  • Disconnect devices you're not actively using
  • If you need more connections, some phones allow increasing the limit in hotspot settings

Step 5: Restart Your Phone

A restart often resolves temporary network glitches.

  • Restart your Xiaomi phone
  • After reboot, turn on the hotspot and test

Advanced Fixes (If Basic Steps Don't Help)

Step 6: Check Your Data Allowance

Some UK carriers disconnect hotspot when you reach a data limit or fair usage policy threshold. This is especially common on MVNOs like Giffgaff, Tesco Mobile, and Lebara.

  • Check your data balance in your carrier's app
  • If you've reached your limit, wait until your allowance resets or purchase additional data
  • Some carriers have separate tethering allowances—check if you've used yours

Step 7: Keep Phone Plugged In

Keeping your phone plugged in while tethering can help prevent battery-related disconnections during long tethering sessions.

  • Connect your phone to a charger while using hotspot
  • This can help prevent battery-related disconnections

Step 8: Change Hotspot Timeout Settings

Some Xiaomi devices have a hotspot timeout setting that automatically turns off the hotspot after a period of inactivity.

  • Settings → Connection & sharing → Personal Hotspot
  • Look for Timeout or Auto-off settings
  • If available, set it to Never or the longest available period

Step 9: Reset Network Settings

This resets Wi-Fi, mobile data, and Bluetooth settings without deleting your personal data.

  1. Settings → Connection & sharing
  2. Select Reset Wi-Fi, mobile & Bluetooth or Reset network settings
  3. Confirm the reset
  4. Restart your phone
  5. Set up your hotspot again

When to Check Your Carrier's Tethering Policy

Before spending time on advanced troubleshooting, check these carrier-related factors:

  • Check your tethering allowance – Some plans have a separate tethering allowance
  • Check fair usage policy – Some carriers may reduce tethering speeds or disconnect after heavy usage
  • Check plan restrictions – Some cheaper plans restrict tethering entirely

If your carrier restricts tethering, the hotspot may disconnect regardless of your phone settings.

When to Contact Your Carrier

Contact your UK carrier if:

  • You've checked your data allowance and still have data but hotspot disconnects
  • Your carrier confirms tethering is restricted on your plan
  • There's a known network issue in your area affecting hotspot stability

Contact Xiaomi UK Support

If your hotspot still keeps disconnecting after completing all steps, contact Xiaomi UK Support through the official channels:

  • Xiaomi UK Support website – Official support portal for UK customers
  • Feedback app – Use the built-in Feedback app on your Xiaomi device
  • Xiaomi Community – Post in official Xiaomi community forums, including UK-specific threads

Final Verdict

If your Xiaomi hotspot keeps disconnecting, the most common cause is battery optimisation turning off the hotspot to save power. Disable battery optimisation for system apps and check whether hotspot drops only after the screen turns off. Review your data allowance—some UK carriers disconnect hotspot when you reach a limit. If the issue persists, reset network settings or check your carrier's tethering policy.

Quick summary:

  • Disconnects when screen turns off → Disable battery optimisation; check screen lock behaviour
  • Disconnects after a few minutes → Check data allowance; keep phone plugged in
  • Disconnects with multiple devices → Reduce connected devices
  • Random disconnections → Reset network settings; check carrier policy
  • Started after HyperOS update → Check battery optimisation settings; reset network settings

Xiaomi Equalizer Settings: Best Sound for Headphones & Earbuds (UK 2026)

How to Boost Headphone Bass on Xiaomi Phones (MIUI Guide for UK Users) Music is closely tied to emotions, and for many UK users, headphones are a constant companion throughout the day—whether commuting in London , relaxing in a Manchester flat, or catching up on podcasts in Birmingham . Naturally, everyone wants the best possible sound quality from their Xiaomi device, without relying on third-party apps that take up storage space. Why Bass Matters Before boosting headphone bass, it’s worth understanding the basics. Humans can hear frequencies from 20Hz to 20kHz. The lower end, below 250Hz, represents bass sounds. Within this range, the lowest frequencies contribute to deep bass, while slightly higher frequencies provide “punchy” bass. MIUI’s equaliser allows you to tweak these frequencies, regardless of the headphone model—be it Mi AirDots , Redmi AirDots S, or higher-end wired headphones. Setting up the equaliser properly is crucial for achieving the richest sound experience...
