Samsung One UI 7 Battery and Performance Issues: Insights from Users in Sweden and Spain

One UI 7 brought new features, but some Samsung users in Sweden and Spain report battery drain, overheating, and performance slowdowns. Here’s what we learned and how to fix common issues based on real user experiences.

After updating to One UI 7, I noticed my Galaxy S22 (Telia, Sweden) battery dropping faster than before. Friends using the same update in Spain with Movistar and Vodafone España reported similar issues — including lag in Samsung Health, overheating during streaming, and shorter standby times. This guide summarizes real user experiences and practical solutions.

1. Common Battery Issues Reported

  • Fast drain even in standby (especially on Telia and Telenor Sverige networks)
  • Battery drops during light browsing or social media apps
  • High battery use by Samsung Health, Bixby routines, or widgets
  • Overheating when using 5G on Tele2 or MásOrange

Users often forget to check app-specific battery usage. In my test, Samsung Health alone accounted for ~15% of daily drain after the update.

2. Performance Issues Observed

  • Lag when opening Samsung Wallet or Camera app
  • Delayed notifications on WhatsApp and Gmail
  • Stuttering animations, especially with Edge Lighting enabled
  • Slower app launch times on older A-series models

Galaxy S22 Ultra on Hi3G (Tre) showed smoother performance after clearing cache for Samsung Health and restarting the device.

3. Steps to Improve Battery Life

Optimize App Usage:

  1. Settings → Battery and device care → Battery → Battery usage.
  2. Restrict background activity for apps using excessive battery.
  3. Disable unnecessary widgets (weather, fitness, news feeds).

Adaptive Battery & Power Saving:

  1. Settings → Battery and device care → Battery → More battery settings.
  2. Enable Adaptive battery.
  3. Use Medium or Maximum battery saver during low activity.

Screen & Display Adjustments:

  1. Lower screen brightness or enable adaptive brightness.
  2. Motion smoothness → switch to 60Hz if using Galaxy S22/S22 Ultra.
  3. Turn off Always-On Display and Edge Lighting animations.

4. Reduce Overheating

One UI 7 adds new background services and animations. Network usage (5G/VoLTE) also contributes to heat.

Steps:

  1. Settings → Connections → Mobile networks.
  2. Test turning off 5G/VoLTE temporarily on Telia, Tele2, Telenor Sverige, Movistar, Vodafone España, MásOrange.
  3. Use Wi-Fi for intensive tasks where possible.
  4. Close high CPU apps manually after use.

5. Update System and Apps

Samsung system apps and third-party apps may not yet be optimized for One UI 7.

Steps:

  1. Galaxy Store → Menu → Updates → update all Samsung apps (Bixby, Health, Wallet).
  2. Google Play Store → update third-party apps.
  3. Restart device after updates to recalibrate performance.

6. Observations from Sweden & Spain

  • On Telia and Telenor Sverige, adaptive battery improved standby by 10–15%.
  • On Vodafone España and MásOrange, disabling 5G during streaming reduced overheating.
  • Older A-series models benefit significantly from limiting Edge panels and widgets.
  • Some users noticed Bixby routines re-enable automatically after One UI 7 updates — check Side Key settings.
