To address the battery drain concern, we recommend performing additional troubleshooting steps to identify the root cause of the issue. These steps may include:

1. Update Software: Ensure that your device's software and related apps are updated to the latest version. To update your mobile device's software, follow these steps:
   - Step 1: Go to Settings > Software update.
   - Step 2: Tap on Download and install.
   - Step 3: Follow the on-screen instructions.

2. Setup Phase: Your new phone’s battery may initially drain faster as you set up applications and features. This is part of the setup phase, and background operations are optimized during this time. Allow a few days for all background operations and syncing to complete.

3. 5G Service Impact: While connected to a 5G network, your phone may consume more battery than usual due to the high-speed processing of large-capacity data. Consider optimizing overall usage and adjusting background usage limits.

4. Optimization Steps:
   - Open Settings > Battery and device care > Optimize now.
   - Adjust Background usage limits: Settings > Battery and device care > Battery > Background usage limits.

5.  Use adaptive battery: Settings > Battery and device care > More battery settings > Adaptive battery.

For Samsung Apps, please try to install the apps using Galaxy store.
