Not sure on the technical details of exactly how long they last, but I've heard similar things several times before.

Always depressing to be reminded of this. Haven't had many fail, but honestly haven't tried a lot of my 3DS/Vita games in a while, so who knows.

If nothing else tho, it's nice to have an excuse to revisit some things. Once you boot it up, you might find yourself enjoying the reminiscing. :)

Image of a tweet on Bluesky that says "Friendly Reminder: 3DS, Vita and Switch all use a type of flash memory that needs an electrical charge every decade or so to keep the game data from corrupting.  TLDR: Boot up all your games and make a save on them to help preserve them into the future!"

Your LttP cart, assuming you already changed the battery, could have a bad SRAM chip. You can FRAM mod the cartridge to both save it and remove the requirement for a battery at the same time.

Also worth checking all the traces from the cart connector to the SRAM chip.

    I'll keep that in mind. Quite a few of the games need a battery change but I think you're right about LttP. I emulate though so it's not as essential as it used to be, it'll be more relevant when I want to share the old ways with my kids when they're a little older.
