That’s great for you, but not everyone has such a flawless expierience. Maybe your standards are lower than others.
Many others report their battery life or performance degrade when they update their older devices so no... it’s not “completely debunked”
Why not, when things go wrong with individual upgrades, fingers of causality are immediately pointed at Apple conspiracy.
Seems to me I have as much evidence, or lack of, as the failure threads.
You see actually my standards are much higher. I expect extraordinary claims to be backed by extraordinary evidence.
My Anecdotal claim is at least as valid as those negative claims. And since millions have just updated I invite them all to document their success as well. Perhaps several million threads might sway the few conspiracy theorists.
Just a few thoughts to mull over.
