I never had issues with CF cards on my cameras for more than ten years, nor with SD cards in 750D for more than one year. However on phones that's a totally different story.
I noticed three SD cards died this year on my Windows phone which sounded strange for me. All three were high quality lexar and sandisk 64 GB cards, they became corrupted: The data was there, you can read it, but you can't write anything new, you can't format it.
My own interpretation is cards have a limited read/ write number of cycles which is hard to reach on cameras easy to reach on mobile phones especially when apps are stored on the card, mainly apps that do a lot of disk writing like web browsers, the same thing happened on my father's Windows phone.
On my wife's phone, the apps are stored on the phone memory only downloads, photos and videos are on the cards it has been there for two years and counting.
So my recommendations for longer cards life would be, limit the read/write use, don't let software create temporary/ swap files on them, personally I don't review/delete photos on camera, I leave everything then after downloading photos I delete faulty ones.
