I'm sorry to hear that you're experiencing battery drain issues on your Samsung Galaxy Tab S6 Lite after updating to One UI 5.1. Battery drain problems can be frustrating, but there are a few things you can try to improve the situation:
1. Check for battery-draining apps: Go to Settings > Battery > Battery usage to see which apps are using the most battery. If you notice any apps consuming a significant amount of power, consider uninstalling or disabling them.
2. Disable unnecessary features: One UI 5.1 offers various features that might consume more battery, such as Always-on Display, Adaptive Brightness, or Background network usage. You can disable these features or adjust their settings to optimize battery life.
3. Optimize battery usage: Within the Battery settings, you'll find an option called "Power mode" or "Battery optimization." Ensure that it is set to "Optimized" or "Adaptive battery" to prolong battery life.
4. Clear cache and data: Occasionally, cached files or app data can cause battery drain. Clearing the cache and data for problematic apps might help. You can do this by going to Settings > Apps > [App name] > Storage > Clear cache/Clear data.
5. Disable unnecessary notifications: Frequent notifications can wake up your device and drain battery. Consider disabling notifications for apps that aren't crucial.
6. Perform a factory reset: Since you've already performed a factory reset, this step may not be necessary. However, if the issue persists, you can try a second factory reset to ensure a clean installation of the operating system.
If none of these steps help, you may want to consider contacting Samsung support or visiting a service center to further diagnose the issue. They might be able to provide more specific guidance based on your device's configuration.
