Hi and Welcome to the Community!
Given your description, I'd deduce low/poor signal from your mobile service provider. Digital devices modulate their power consumption depending on the strength of signal they receive from the carrier tower. Lower signal strength/quality, higher battery drain. To firmly check that, you need to contact your mobile service provider as it's there network that is the cause. It is possible that they have some problems in the areas you are in.
You could also attempt to boot into Safe Mode, so as to suppress all 3rd party apps from auto-launching (even if you don't see them in the AppSwitcher ribbon, they can be running):

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.
If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.
But if the behavior continues in Safe Mode, then you may need to consider more drastic actions -- WIPE, OS Reload, BBSAK Wipe/Reload, and the "Bare Bones" OS Reload Process. To prepare, you should be sure that you have a full backup to your PC...please review the Backup link in my auto-sig on this post for instructions.
