Apple appears to have three new Smart Battery Cases ready to go
If clues in Apple's recently released iOS and watchOS updates are anything to go by, we may see new Smart Battery cases for all three of the latest iPhones before the end of 2018.

Apple Smart Battery case
An icon found in watchOS 5.1.2 showed off a new Smart Battery Case that featured a vertical camera cutout such as that found on the latest iPhones. The updated case has a similar design to the original, but lacks the extended "chin." Rather, the new case extends only minimally from the bottom of the iPhone where it connects to the Lightning port.
Now, images have been dug up that possibly show off the case. In the photo, there are obvious changes to the back of the case versus the previous model, which used to have a rectangular hump in center. The battery for the updated case now extends to the bottom, leaving still a bump towards the top.

Apple received a bit of criticism on the original design that Tim Cook himself had to refute. It seems the new design is a bit of a compromise, keeping the top bump to allow for taking the phone in and out via the flexible material, but shoring up the bottom.
The steepness of the bump also seems to have been smoothed out, making the slope a bit more gradual.
Apple's Smart Battery case was first released for the iPhone 6s. Based on the new model numbers found in the code -- A2070, A2071 and A2171 -- by 9to5Mac, we could see versions of the case for the entire range of iPhones released in 2018. This would be the first time Apple has released the battery case for any of the larger phones.
These cases could be released any time, as Apple has released products this late in the year in the past. Even earlier this week we saw Apple's official clear case for the iPhone XR finally go on sale.
Other's have come to fill the void with battery cases in Apple's abcense, including one from Momemt which supports their lenses and wireless charging.

I'll be first in line to buy one for my iPhone Xs
So, it will only make the phone taller like any other case. It’ll be thicker for obvious reasons. The bulge is fine, if not looks better than other battery cases who compromise the other way with big camera wells.
But where are the up to date imacs?
Yeah, looks like Coffee Lake iMacs are now headed for Spring. Maybe February at the earliest. Hoping for a new form factor myself.
At the same time, I also have a tiny Anker PowerCore II 6700 and a one inch lightning cable for times I know I’ll need longer battery life.
Tough decision.
It looks pretty = useless piece of trash
It has nothing I can trash about = how about doing something more important?
No wonder why Apple communities suck these days.
We're only talking about the greatest devices ever designed by man for f's sake!
Best.
I hear you Payeco. Back in the day, I had the white plastic 3GS and I bought the white Mophie battery pack. It added a little bulk to the phone. I only really used it when I traveled by plane.
It was so comforting to look down and see the 4 little blue lights showing the charge status. It meant I could use the phone on the plane and not fret that I'd have enough charge to make calls when I landed.
With the white plastic of the battery case and the blue lights, my brother-in-law said I looked like a Star Wars Storm Trooper!
Best.
But I'll have to buy a new phone to use one of those Apple cases, and the SE isn't conducive to a satisfactory wireless experience for me.
