Let me provide you some troubleshooting steps so you can diagnose your problem yourself instead of visiting to the service center.                                                                  Step (1):Perform Battery Optimisation. Settings > Select Device Maintenance/Device Care > Optimize > Optimize all options like Battery, Storage and Memory.                                  Step(2):Turn off Bluetooth, Wi-Fi, mobile hotspot, NFC, etc a). Swipe down on the home screen to open the notification panel. b). Tap on Bluetooth, Location/GPS, Wi-Fi, Mobile hotspot, NFC, etc. to turn off.      Step (3):Kindly check whether the mobile network fluctuates frequently or network signal is low in your area. In both cases, the battery will drain considerably fast. Step(4):Reduce display brightness level. a). Swipe down on the home screen to open the notification panel. b). Turn on the Auto-brightness option if available. Step(5):Adjust screen timeout settings. Go to Settings > Display > Screen timeout > minimum screen timeout.      Step(6):Update apps. Kindly check which application is or interface is using more battery from device care. And try to update the app or avoid using that app.               Step (7):Close background running apps.

Exit safe mode: Restart the device.        Step(10): Try your device in safe mode.           As you were facing battery drainage issue in your device, I have provided you some basic trouble shooting steps and your concern has been resolved.                          "If the problem is solved click the three dots & click solution".
