Un-explainable rapid battery drain

I have a Kyocera Duraforce Pro I got at Christmas last year and about 3 days ago quite literally out of the blue it developed a severe battery drain. I'm talking damn near 2% per minute is lost. In my settings I enabled every battery saving feature I could find and disabled anything that wasn't absolutely necessary to me. I even let my parents look at it and they didn't see anything abnormal in my settings or apps. However the problem hasn't gotten any better!

This battery drain is occurring even when the phone is idle too. I had it in my pocket earlier today with 50%. I go to check the time about 15 minutes later and it's already down at 32% and I didn't even use the phone!

According to the Battery section of the settings, about 60% of my battery drain is from "Android System" and all my apps and stuff are using less than 1%... I downloaded Malwarebytes app and ran a virus scan but it came up with nothing so I'm really confused!

TL;DR my phone is losing nearly 2% per minute even when idle and in my pocket, what gives?
 
Did you factory reset it yet? That's pretty much the first step with any phone issue.
 
Im not sure. If everything looks normal im guessing it might not have been maintained properly.
(1) Using a battery phone and running down to near zero) Big mistake.

(2) Over charging. example plugging in overnight to charge. (over charging).

the above will rack and take the life out of the battery.

Both of these aren't true anymore. Every modern device has built in overcharge protection. It'll just stop charging when full and then top it off as it slowly drains.

Also batteries are fine to drain down to 0, they have a bit of a capacity buffer to where the phone will shut down before it truly is empty.

Try a new battery, sounds like it might be faulty.

It probably is faulty with my dumb luck. And the phone is only 3 months old and this all just began 3 days ago
 
Seems kind of odd since it isn't very old. If the factory reset doesn't do anything I'd be inclined that it was defective from the factory.

Modern li-ion charging circuits will place it into a trickle charge once the battery is near capacity, so they don't over charge.
 
I have smart chargers but not for the phone. your right though. its just a thought.
A cheaper smart phone may not work as you described but the technology is there.
I still saying running down to zero is a bad idea. wouldn't go below say 20%.
 
Ok idk what happened but after last night the issue stopped, I've had great battery life these last 2 days and I didn't touch anything ... I don't know what the hell was going on lol
