All of my succulents are in containers. Most of them are in small pots. Most days the water in the pots dries out quickly, sometimes in a day or two, and my succulents are left bone dry.
If you gradually introduce your succulents to the direct sunlight (increasing an hour or so every couple of days), most succulents will tolerate full sun most of the day.
A large plant is much stronger, has a deeper root system, and has likely had time to adjust to the warmer temperatures. While it's still possible for them to sunburn, it isn't as common.
