Optimizing Samsung Battery Life in Sweden After the One UI 7 Update

After the One UI 7 update, Samsung users in Sweden may notice faster battery drain. This guide provides actionable steps to optimize battery life on Galaxy devices using Telia, Tele2, Telenor Sverige, and Hi3G networks.

I experienced significant battery drain on my Galaxy S22 using Telia in Stockholm after updating to One UI 7. Friends on Tele2 and Telenor Sverige reported similar issues with their Galaxy S22 Ultra and A-series phones. One UI 7 introduces adaptive animations, background services, and new app behaviors that can affect battery performance. Here’s what actually works to improve battery life in Sweden.

1. Analyze Battery Usage

Identify apps consuming excessive power after the update.

Steps:

  1. Settings → Battery and device care → Battery → Battery usage.
  2. Look for apps with high battery consumption.
  3. Restrict background activity for apps that are rarely used.

Samsung Health and social media apps were the main culprits on my Galaxy S22 using Tele2 SIM.

2. Enable Adaptive Battery and Battery Saver

One UI 7’s adaptive features help reduce unnecessary background processes.

Steps:

  1. Settings → Battery and device care → Battery → More battery settings.
  2. Enable Adaptive battery.
  3. Turn on Battery saver during low-activity periods.

3. Adjust Screen Settings

Screen brightness and refresh rate significantly impact battery life.

Steps:

  1. Settings → Display → Brightness → enable adaptive brightness.
  2. Settings → Display → Motion smoothness → set to 60Hz for Galaxy S22/S22 Ultra.
  3. Turn off Always-On Display to reduce background power usage.

4. Manage Background Apps and Widgets

Background apps and widgets can silently consume battery.

Steps:

  1. Remove unused widgets, especially weather, fitness, and news feeds.
  2. Settings → Apps → select high-use apps → Battery → Background activity → Restrict if not critical.

5. Carrier-Specific Optimizations (Sweden)

Telia, Tele2, Telenor Sverige, and Hi3G sometimes enable features that increase battery drain.

Steps:

  1. Settings → Connections → Mobile networks.
  2. Disable VoLTE or 5G temporarily for testing.
  3. Use Wi-Fi whenever possible for heavy tasks.

Switching from Hi3G to Tele2 during testing improved standby battery by 7–10% overnight.

6. Update System and Apps

Ensure all apps are optimized for One UI 7 to reduce battery issues.

Steps:

  1. Galaxy Store → Menu → Updates → update all Samsung apps.
  2. Google Play Store → update all third-party apps.
  3. Restart the phone after updates to recalibrate battery reporting.

7. Observations

  • Adaptive battery settings work best on S-series flagship devices.
  • A-series phones benefit from restricting background activity more aggressively.
  • Some users notice that Samsung Health step counting can still consume power even when restricted — check app permissions.
