We checked fourteen things on an iPad Pro connected to a Studio Display and could not find one that had stopped working. Then we tried to move a window.
Our Apple Watch Series 7 will never get watchOS 27. The update screen tells it that it is up to date. We checked what a dropped watch still does with a phone on iOS 27.
We pulled the 140W brick, left a 16-inch MacBook Pro on the Studio Display’s cable alone, and pinned all eighteen cores for thirty minutes. The battery went up, not down.
A 2022 iPhone and a 2026 iPhone, both measured 24 hours after updating to iOS 27. Both got faster. The four-year-old phone gained 4.8 points more.
Every guide says wait a few days before judging an update. We measured during the wait, watched reindexing take a quarter of a CPU, then measured again after.
The same MacBook Pro ran the browser 12.4% faster and every compute test 0.7% to 5.6% slower after the update. Same machine, same day, same measuring session.
Five devices with measured baselines from the week before. All five got faster after the update — by between 4.3% and 24.9%. The spread is the part worth reading.
A four-year-old MacBook Pro at 86% battery ran every test at full speed unplugged. The widest gap we found was 1.2% — inside this machine’s run-to-run noise.
The same Mac, measured twice an hour apart, came out 20% apart. The machine never changed. The contaminated run made an older Mac look faster than a newer one.
Eight minutes at full load on three MacBook Pros. None of them throttled — the oldest finished 2.1% slower than it started, which is inside its own noise.
