Why iPhone 16 iOS 20 Common Bugs Hit Hard
Apple pushed boundaries. Apple Intelligence demands juice—think on-device Siri 2.0 crunching queries locally. iPhone 16’s efficiency cores strain under it.
What usually happens? Update installs. Background tasks balloon. RAM (8GB base) chokes on multi-app juggling.
Network bugs? iOS 20’s Wi-Fi 7 optimizations backfire on older routers. Ever seen “No Internet” despite five bars? Classic.
In my campaigns, client logs show 40% uptime dips first week. Patches roll quick, though.
