Is it "better then" or "better than"?
"Better than." Than is for comparisons; then is for time.
Contexti
The then/than swap is one of the most common autocorrect-proof typos because both words are real, spell-checked English — only the meaning distinguishes them. It shows up most in fast typing (DMs, code comments, product reviews) where the writer hears the word in their head and grabs the wrong form.
A little moreii
Any sentence that compares two things — taller than, faster than, better than — takes than. Then fits sequences: first this, then that. If you can swap after that into the sentence, you want then; otherwise, than.
Examplesiii
This phone is better then the old one.
This phone is better than the old one.
Two phones being compared → *than*.
She ran faster then he did.
She ran faster than he did.
Comparing speeds → *than*.
Watch foriv
If the sentence is really about sequence — first I saved the file, then I ran the build — then is correct. The giveaway: can you replace it with after that?

Time versus comparison — two different jobs, one letter apart.
