Looking for self battery replacement advice

I have an iPhone 6s with a battery at 77%, but still in "peak performance". Further down the battery health page it says "your battery's health is significantly degraded". I do notice a significant decrease in usable time so I'm planning to replace the battery myself, doesn't seem too bad. Just a few questions:

Detach battery cable first before anything else, and attach battery cable last after everything else, right?
Not planning to take off the display, just gonna find my iPhone box to "rubber band" it at 90°, feasible?
Looks like there's adhesive around the screen, do I need to put new adhesive when I put the screen back?
What capacity should I get? The original 1715 or can I go something higher? Say around 2000
Any battery brand that you recommend?

Thanks a lot!

Here are my personal recommendations.

Whenever you are doing a repair it’s always a good idea to disconnect the battery first and connect it last.
While it’s possible to change the battery without taking off the screen I would highly recommend removing it. This just adds an extra layer of safety should the screen slip while trying to remove the battery. Apple uses a really strong adhesive.
The adhesive around the screen is for water resistance. It’s not necessary however just know that you will loose that water resistance at that point. Honestly, I don’t bother. Even phones that have it still get wet if they are dropped in water. This one is really up to you.
This one is up to you. As long as all the voltage specs are the same, the extra capacity means you’re phone will just run longer between charges.
I would recommend getting a battery from a repeatable source such as iFixit. You never really know what you’re going to get when you order online so look for a vendor that has a warranty and will allow you to return the battery if needed.

A few extra tips. It’s very common for the adhesive strips to break off when you are removing them. Pull back as straight as possible but make sure you don’t snag the strips on anything. Pull slowly and take your time. I recommend starting with the strip on the left. If you can get that one out but not the right one you are in a better position if you need to pry the battery out. If you need to pry use plastic tools only and pry towards the logic board never towards the volume buttons. (If you elected to not take the screen off I would highly recommend if you get to this point.)

Some people like to use a little heat to loosen the adhesive strips. A heatgun is a good options but if you don’t have one then a hair dryer on high heat on the back of the phone should work as well.

Good luck and take your time. Also, make sure you keep track of what screws go where as they are different sizes and it makes a difference where they go.

If i may add one thing: Removing the vibrator/taptic engine helps a lot when removing the adhesive strips under the battery. It's only 2 screws on the iPhone 6S and the taptic engine is gone, so it's not really more time consuming.

Thank you for your input. You said "hair drier" on the back of the iPhone. I've seen some videos of people heating it in the front, is there any particular reason you said the back?

Also the reason I was not gonna detach the screen is that I think there are three connectors and I worry about shorting them. But if I disconnect the battery first I shouldn't worry right?

Thank you.

As long as you remove and reconnect the screen ribbon cables without the battery attached you'll be fine. Even if you didn't in doesn't mean you'll short anything out but it's defiantly not advised. I suggested the back as the adhesive strips are on the other side. I don't know if you'll get enough heat transfer if you heat from the battery side. The back is also metal and that will help with the heat transfer. Also, Pontus Hernberg's suggestions about removing the taptic engine is a really good idea. It should make pulling on the adhesive strips a lot easier.
