Color on iPhone 11 looks washed out compared to edits made on MacBook

I have the same problems with my iphone 11!!! I don't like the display! it's worse than my previous iphone xs. it looks washed out, more yellow than orange. 

John, iPad [and iPhone] factory calibration is pretty reliable, they are quite consistent - of course brightness is very adjustable. 

IF your main computer screen is correctly calibrated and profiled and if you save images with the sRGB ICC profile embedded they should reproduce well on. the iOS device. My iPhone X matches my calibrated Eizo Coloredge screen very well. 

Here's an Adobe RGB image to try on the computer - and a version for the 1Pad / iPhone (view in Safari)

With all set up correctly on your computer, these should match well

I hope this helps

Every MacBook Pro with Liquid Retina XDR display undergoes a state-of-the-art factory display calibration process on the assembly line to ensure the accuracy of the P3 wide color panel and the individual backlight LEDs. In addition, the factory calibration process enables sophisticated built-in algorithms to accurately reproduce a variety of color spaces used by media workflows today, including sRGB, BT.601, BT.709,​ and even P3-ST.2084 (HDR).

The same is true of your iPhone. 

As to the reported mismatch, I hope we can still get to a solution for you. 

If your images have embedded profiles then the only way you can achieve your goal of a closer visual match on both devices is to make sure both display ms are profiles and both display profiles are used.  But this only provides a best possible match and everyone's results will vary.  That's normal in the wild where color managed workflows are few and far between

Is this just due to the display capabilities on the new device? Do I really need to edit elsewhere in order to edit in a way that reflects how the images will look on most devices that people view content on?

Looking for a solution to have the images I edit on my laptop look identical when I transfer them to a phone.

You cannot control how others see your images on the web (or elsewhere). Yes, saving as sRGB is a good start but you have no control over others who may or may not be using color managed applications (without, sRGB is meaningless), if or how they calibrate their displays, etc. The best you can do is control your images on your end using color management.

Have you embedded the sRGB profiles in each image?  If not do that and the color should be closer.  The problem here is that your monitor and your phone, more than likely do not have calibrated displays so there will be differences.  Having an embedded profil should reduce the problem but unless you want to calibrate both the difference will remain.
