bigger icons in iphone xs

Not sure what you are referring to when you say "As you see" above? Did you mean to attach a screenshot?

9TO5Mac has this statement:

One feature difference betweeniPhone XS andiPhone XS Max is Display Zoom, an accessibility feature that makes content on the screen appear larger than the default resolution. This was introduced on iPhone 6 and iPhone 6 Plus, but was notably absent on iPhone X. The display feature is still absent on iPhone XS, but the larger iPhone XS Max version restores it.

Followed by this article: https://9to5mac.com/2018/09/26/iphone-xs-max-display-zoom/

So it sounds like the XS does not have that feature available.

The Display Zoom is not likely to change since it appears to be prohibited by the physical device as the article I linked for you points out:

iPhone X and iPhone XS have a larger 5.8-inch display but a different aspect ratio to iPhone 5 and iPhone 6 style phones. For this reason, there are no smaller versions of apps that can easily scale up for Display Zoom.

If you place your finger in the top right corner of the iPhone screen and slide down, you can see the Control Center, and that is where the battery percentage is now housed. You can also pull it down without lifting your finger just so you can see what it is, then move it back up with your finger still on the Control Center panel to put it back.

Best,

Works on my Xs Max

Unfortunately, the screenshot didn't post here. But, as you suspected, it is not a feature that is available on the iPhone X or XS.

Sorry,

GB

Battery percentage was moved to Control Center on the iPhone X under iOS 11.
