Google counts from first availability on the US Google Store. The Pixel 6, out in October 2021, gets five years, so October 2026 is the end. Samsung says only "up to 7 years" and publishes update lists instead of per-model end dates.
A 200MP phone sensor outputs 12MP by default because it bins sixteen 0.6μm pixels into one. Effective pitch becomes 2.4μm and area per pixel grows 16x, but total light on the sensor never changes.
The recommended TV viewing distance is the screen diagonal times 1.2. Here is where that multiplier comes from, and how to reverse it into a maximum screen size.
Convert refresh rate to time and 60Hz is 16.7ms, 144Hz is 6.9ms, 240Hz is 4.2ms. Going from 60 to 144 buys 9.7ms; going from 144 to 240 buys just 2.8ms. The same point is where cable bandwidth starts to bite.
A laptop spec sheet does not list one TDP but three. Using Intel's official power figures and the 56-second Tau window, here is why identical Core Ultra 7 155H laptops benchmark 1.95x apart.
QLC drives match TLC only while the SLC cache holds. Once it drains, writes collapse to 50-150MB/s and a 100GB copy stretches to nearly 12 minutes — and the fuller the drive, the sooner that cliff arrives.
Thunderbolt 5 and USB4 v2 both top out at 80Gbps. What separates them is not the number but the obligation — asymmetric 120Gbps, 64Gbps PCIe and 140W charging are certification requirements on one side and vendor options on the other.
A 1-inch sensor measures 16mm diagonally, not 25.4mm. Converted to area, 1/1.3" and 1/1.4" differ by 16%, and 1/2.55" is three times smaller.
Getting 4K 120Hz from a laptop to a TV depends on the ports at both ends, not just the cable. Calculating bandwidth per resolution shows exactly where 18Gbps and 48Gbps diverge.
A six-setting countertop uses 0.68kWh and 8.7L a cycle; a twelve-setting built-in 0.97kWh and 14L. Reduced to a per-setting basis from published specs, a Grade 1 fourteen-setting model draws less than the six.
