Samsung phone write cycle count app?

I have a friend whose phone slowed down quite a bit, he did the usual stuff (clear cache, remove unneeded apps including stuff running in the background) but it's still frustratingly slow. It's a Samsung and it's 4 years old and he uses it a lot.

I read about write cycle limits per memory cell here:

"Note that TLC is a type of NAND memory pioneered by Samsung. It's the cheapest to produce but has the worst durability: 4,000 write cycles per cell versus 10,000 in the more standard MLC type. This might be why Samsung devices have a reputation for slowing down more than non-Samsung devices."

I was wondering if anyone knows of an app that shows the write count for memory in an Android phone.

** Google the topic.

I have read that such phones slow down by design as they get old, yep phones do know how old they are. Makers claim it is to preserve running time on a battery that has lost capacity - as Lithium types all do.

Others suspect it is to make you buy a new phone...

so lets assume a 2016 phone has 16GB

so that's 64 TBW ...

Are you saying 64 Terrabytes written? That sounds like an awful lot. It's probably more along the lines of what Phil said. Still, too bad there's no display of the memory stat's. Thanks, Mike

Thanks, Do you think running a non-std OS bypasses that programming, if it exists?

It does a bit, maybe TBW calculations should include division by whatever block size the flash uses?

I don't think number of write cycles is about deliberate slowing down, it's about reaching the point that writes start failing.

I've heard complaints about Apple deliberately slowing down older devices, other manufacturers not so much.

Maybe: "Samsung's HIDDEN Diagnostic Mode [Test Mode]" If you look at the tests offered, the button in the lower left is for an "MLC" test, which might be a memory test. I don't have access to a working Samsung phone to test this.

Hint: Samsung phone model number? It might be amusing to verify the type of SSD used in the phone. Also, the larger SSD chips use a rather large SLC area as a cache, which drastically reduces access wear and tear in the MLC/TLC/QLC memory.

There are also apps that claim to do a "storage stress test": "Phone Check and Test" I'm not sure that beating up on the Flash RAM is a good idea if it's really that fragile.

Thanks Jeff, I'll see if he's willing to try these.
