Question: MacBook Pro 2012 battery draining issue

I am owning MacBook Pro 2012, installed with High sierra just last week. But I noticed that battery has started draining like flowing water. It works just for 3 hrs hardly with normal surfing on Safari. Also found that MacBook start heating from charging point side. So can anyone suggest me best way to get back to normal life of 6 hrs?

Thanks in advance.

MacBook Pro, macOS High Sierra (10.13.3)

Report shows that system in excellent condition. Battery health is stated as normal.

Try starting up in Safe Mode.

Once in SafeMode, click the “Restart” button at the bottom.

Battery: Health = Normal - Cycle count = 20

Is this a replacement battery? Even though that model stayed in the line until Oct 2016 I would expect the original battery to have more than 20 cycles. If it is the original battery it could be degrading from lack of use. I try to run my MacBook Pro of the same model on battey for several hours at least once a week.

This is not good:

You will probably need a new hard drive soon and you do not have Time Machine set up. That could mean everything on the computer will be lost when the drive fails. get an external drive for backups NOW and start using it.

I replaced the mechanical hard drive in my 13-inch 2012 MacBook Pro with a 500GB SSD last November and my MBP feels like a new computer. Everything is fast. This is the kit I used:

OWC DIY KIT: Express USB 3.0/2.0 2.5" Enclosure +... at MacSales.com

It is an easy at-home job and takes no specific knowlege of computer workins to accomplish. NOTE: Due to a design issue with that specific computer model, replace the hard drive cable at the same time you upgrade the hard drive. The cable is cheap, avaiable, and as easy to change out as the hard drive:

Here is a video of the hard drive install: MacBookPro9,2

Thanks Allan, I believe this will be definitely helpful to me. Even I am planning to install 256GB SSD but I afraid that would it be helpful to me by prolonging the battery life? Or should I go with downgrading OS to EL capitan?

Because in one of blog, I read that High sierra causing battery draining a lot. However, I am going to visit apple care soon for battery checkup.

Again thanks for your valuable response.
