I usually use the advanced version of the full site on my old iPhone 4S and had been having virtually every problem discussed with the exception of pop up ads never being a problem. I used this for a solution to all of the problems.
Click on TOOLS at the top of the page or wherever you can find it with your device software and site style selections.
That will open a little grey window with options, click on User CP, this will open User Control Panel
Under the Settings Options menu, click on Edit Options
On that page scroll down to Thread Display Options. The very first setting is labeled Visible Post Elements
Unselect Show Signatures, by clicking the box to make the checkmark disappear.
Next, deselect Show Avatars by doing the same.
You can leave the Show Images selected by keeping its checkmark in its box. This part is for attached photos and photos that are linked within the body of the post, not the avatars.
Next scroll down to the heading Number of Posts to Show per Page. Select Use Forum Default if that is not showing in that box.
Scroll down to Image Resize and select Default ( Enlarge in Same Window)
Then scroll to the bottom or the end of those options and click on Save Changes
Do not click Reset Fields or you will have to start over.
Sorry to say, I believe most of these problems are caused by our own high definition avatar photos! I also compose most long posts like this in my notes App and paste them in the reply box to avoid possible glitches. With these settings I can load any page in 3 to 10 seconds and have no freezing when scrolling.
