Do a restore to a complete clean state and see if this problem persists.

If it still does. It's time for you to visit the service centre.

Try restoring then retrieving your data via iCloud.

After which go to settings > general > reset > reset all settings.

Give a call to apple hotline.
They can help to do a quick diagnostic test on your battery. If nothings wrong they will ask u to restore ur ios, or go down to service center for further tests.

I went down to qcd recently and they were able to point out my software was corrupted due to certain apps.
