1. Fixing App Freezes & Performance

The A05s has limited RAM. Don't overload it.

Steps 1-3: Speed Boost

RAM Plus: Go to Settings > Device Care > Memory > RAM Plus. Set it to 4GB. It helps keep apps open in the background.
Auto Optimization: In Device Care, enable "Auto Optimization". It clears RAM and closes unused apps automatically daily.
Reduce Animations: Go to Developer Options (Tap Build Number 7 times). Set all animation scales to 0.5x.

2. Solving WiFi Disconnection

WiFi dropping is common on budget modems. Here is the fix.

Steps 4-6: Stable Net

Reset Network: Go to Settings > General Management > Reset > Reset Network Settings. This clears old, buggy WiFi profiles.
Mac Address Type: Tap on your connected WiFi > View More > MAC Address Type. Change it to "Phone MAC" instead of "Randomized MAC".
Disable Intelligent WiFi: Go to WiFi Settings > Intelligent WiFi. Turn OFF "Switch to Mobile Data". It disconnects WiFi too aggressively.

3. Optimizing 5000mAh Battery

One UI Core is efficient, but you can squeeze more juice.

Steps 7-9: Power Saving

Put Apps to Sleep: Go to Battery > Background Usage Limits. Put apps like Facebook and Instagram in "Deep Sleeping Apps".
Dark Mode: Enable Dark Mode. It reduces eye strain and saves a small amount of battery on the LCD screen.
Adaptive Battery: Ensure "Adaptive Battery" is ON in More Battery Settings. It learns your usage patterns.

💡

Galaxy Tip: Use the "Samsung Members" app to run a full diagnostic test on your battery and sensors for free.

4. Cooling Down the Phone

The plastic back traps heat during charging or gaming.

Steps 10-12: Thermal Control

Remove Case: If charging or playing games, remove the back cover. It acts as a blanket for heat.
Limit Multitasking: Don't keep more than 5 apps open. The processor heats up trying to manage too many background tasks.
Fast Charging: If the phone gets too hot while charging, turn OFF "Fast Charging" in battery settings during summer days.

Warning: Use the original Samsung 25W charger (sold separately). Cheap chargers can damage the battery and cause overheating.

Additional Maintenance (Steps 13-15)

Step 13 (Uninstall): Remove pre-installed apps (Bloatware) that you don't use. Long press > Uninstall.
Step 14 (Restart): Use "Auto Restart" in Device Care to reboot your phone weekly at night.
Step 15 (Update): Check for One UI Core updates. Samsung releases stability patches frequently for A-series.
