Safari is draining my battery on Mac out of the blue

As of this afternoon, Safari is draining my battery at an alarming rate. Nothing I was doing changed. It went from using around 20-25 for energy impact to over 100 for the same sites. I tried restarting my Mac, closing Safari and only having one tab open (had 4-5 before this no problem), and clearing my history. I'm running 10.12.2. I tried updating but it won't let me. I just keep getting an error issue. Chrome was doing the same thing which is why I switched to Safari a couple months ago. I'm not sure where to go from here. This page alone as I'm typing is taking up 59 for an energy impact. This is the only page I have open at the time.

MacBook Air, iOS 11.0.2

Backup your Mac.

Force Quit Safari.

Close all windows and quit all applications.

Hold "option" key down and click "Go" menu in the Finder menu bar.

Library will appear between “Home” and “Computer” entries in the dropdown.

Select "Library" from the dropdown.

Click the “List” view button in the Finder toolbar.

Move these files to trash and test.

1. Click open the Caches folder and scroll down the list.

Click open the com.apple.Safari folder.

You should see the Caches.db file.

Right click on it and choose “Move to Trash”.

2. Scroll down the list, click open the Safari folder, select History files and LastSession.plist

Right click on it and choose “Move to Trash”.

3. Scroll down the list and click open the Saved Application State folder.

It can be a single page. I saw unusual and unexpected battery drain on my MacBook Pro a couple of weeks ago. I looked at Activity Monitor and saw that the Amazon home page was using between 25 and 55 units of energy; nothing else was even close. At the time of this screen shot it was at 35:

I had logged in to look up something on Amazon, then opened a new window for Apple's forums with 18 tabs. Each Apple tab used less than one unit. I closed the Amazon page and immediately gained back 45 minutes of runtime.

I was able to make the Amazon site repeat this behavior later.

So use Activity Monitor to see if any one page is using a large amount of energy.

1. Try resetting SMC:

Reset SMC. Choose the method for “If the battery is non-removable”.

https://support.apple.com/en-us/HT201295

2. From the report:

"Battery: Health = Normal - Cycle count = 898"

If resetting SMC doesn't help, even though battery health is stated as "Normal',

with Cycle count running very high, I would try replacing the battery.

Still didn't help. It was doing this on Chrome about 2 months ago, switched to Safari, and then this issue started yesterday so to me that doesn't sound like the battery. Safari is also running very slow in general since this started happening.
