The phone may still be indexing after this major update along with your current apps optimising @Shopon1
Check for any apps that need updating in your Playstore and Galaxy Store.
And soft reboot by turning your phone Off and On.
If this continues then check in your Device Care and Battery Usage what's using your battery.
Some generic troubleshooting tips are …
1. Clear your phone's System Cache Files by turning your phone Off and then from a set series of button presses go into the phone's System Files and clear the cache. No information is lost this way. You may need to insert your headphones or hook upto a computer with your data cable to get to this menu on the phone.
2. First please put the phone in Safe Mode which disables your downloaded app's but let's your stock app's keep working. If the issues stop then this highlights a downloaded app as the possible issue. Come out of Safe Mode and start deleting your most recent downloaded app's one at a time until it stops.
3. As a very last resort back up and remove any relevant sd card and factory reset.
