Dear Samsung Member,
Greetings from Samsung Customer Support!
Please perform the below mentioned steps to resolve the issue:
1. Clear camera application data.
Settings >Apps >Camera >Storage >Clear Data
2. Perform Battery Optimization:- Battery optimization helps you to boost the battery performance of your device.
To check battery optimization:- Settings > Select Device Maintenance/Device Care > Optimize > Optimize all options like Battery, Storage and Memory
3. Kindly turn off the smart features of the device and other connectivity features (like advance feature and Bluetooth, Wi-Fi, etc.) when not in use, which will eventually help you to reduce battery power consumption). Follow the below steps to turn off: Swipe down on the home screen to open notification panel> Tap on Bluetooth, hotspot, etc. to turn off
4. Device network fluctuation:- Kindly check whether mobile network fluctuates frequently or network signal is low in your area. In both cases battery will drain considerably fast. We recommend you to avoid usage in area with low network/fluctuation.
For further assistance, register your concern in Samsung Members Application (Open Samsung Members Application > click on “+“icon > send feedback > error report/ask questions).
Thank you for writing to Samsung.
