How to Reduce Samsung Overheating After One UI 7 Update for Users in Spain

If your Samsung phone gets hot after the One UI 7 update, this practical 2025 guide shows how to reduce overheating in Spain, including settings tweaks, app management, and carrier-specific fixes.

After updating my Galaxy S22 Ultra while on Vodafone España, I noticed the phone heating up during casual use like scrolling Twitter or browsing Google Chrome. Even with MásOrange and Movistar SIMs, the problem persisted. One UI 7 introduced new background tasks, adaptive animations, and network optimizations that can increase device temperature. Here’s how I fixed it.

1. Identify High-Temperature Apps

Start by checking which apps or processes are causing the most heat. One UI 7 sometimes resets app standby and background permissions.

Steps:

  1. Settings → Battery and device care → Battery → Battery usage.
  2. Check for apps consuming excessive battery or running in the background.
  3. Force stop or restrict background activity for high-use apps.

I noticed Samsung Health and Chrome consumed more power after the update, especially on Movistar and Vodafone España networks.

2. Reduce Screen Brightness & Refresh Rate

High brightness and 120Hz refresh can heat the phone faster.

Steps:

  1. Settings → Display → Brightness → enable adaptive brightness.
  2. Settings → Display → Motion smoothness → switch to 60Hz.

Using adaptive brightness on Digi España network reduced heat noticeably during casual browsing.

3. Disable Always-On Display and Extra Animations

One UI 7 adds smoother transitions and widgets that can increase CPU load.

Steps:

  1. Settings → Lock screen → Always On Display → toggle off.
  2. Settings → Accessibility → Remove animations → toggle on.

4. Update Apps and System Software

Some apps may not yet be optimized for One UI 7.

Steps:

  1. Galaxy Store → Menu → Updates → update Bixby, Samsung Health, One UI components.
  2. Google Play Store → update all apps.
  3. Restart the phone after updates.

I found updating Samsung Wallet on MásOrange SIM reduced background heat spikes significantly.

5. Check Carrier-Specific Features (Spain)

Movistar, MásOrange, Vodafone España, and Digi España sometimes activate network features (VoLTE, 5G) that increase phone temperature.

Steps:

  1. Settings → Connections → Mobile networks.
  2. Disable enhanced 4G LTE/VoLTE or 5G temporarily.
  3. Switch to Wi-Fi where possible to reduce mobile radio usage.

On my Vodafone España SIM, temporarily disabling 5G reduced heat by ~5°C during light usage.

6. Clear Cache and Unnecessary Background Services

Residual data and old cache may be causing CPU spikes.

Steps:

  1. Settings → Apps → select high-use apps → Storage → Clear cache.
  2. Settings → Battery and device care → Optimize now.

7. Final Observations & Tips

  • Remove unused widgets, especially weather or fitness widgets.
  • Close apps manually rather than leaving multiple heavy apps open in the background.
  • If overheating persists, a soft reset often recalibrates thermal sensors.
  • Keep track of apps during hot summer months — Spain’s ambient temperature can make overheating worse.
