Bros,here come the problem.my batt drained super fast recently.phone hot.lacking..i closed all the apps still no avail.dignose still the same..time to visit service centre?
1. Do a backup (to SD Card) using the built-in "Backup & restore" function (Setting > General > Backup & reset). Recommend to select external SD Card for the backup file. If you do not have SD Card installed, you'll need to transfer the "LGBackup_yymmdd.lbf" (in \LGBackup) to PC after the backup finishes (and to transfer back before restoring).
2. Perform a "Factory data reset" (Setting > General > Backup & reset).
DO NOT check the "Also erase SD card" if you've a SD Card installed and have stored the backup there.
3. Restore from the backup. Remember to transfer the backup file to \LGBackup folder before launching the restore if you didn't use a SD Card for the backup earlier.
I've done the same for my G4 year back for the same abnormal battery drain issue. I've also factory reset my LG v30+ (yesterday) and v20 (months back) due to abnormal lag in the camera functionality.
