The short version
DJI Pocket 3, sensor 1in CMOS — Why Software Update Policies Should Change What You Buy. Measured on hardware rather than argued from theory, on a device we rate for usable low light to ISO 3200.
A device with seven years of updates is usable far longer than one with two, and that gap now outweighs most hardware differences at the same price.
Why this matters: Security patches, not features, are what determine how long a device stays safe to use.
The mechanism
Manufacturers commit to a number of years of OS upgrades and, separately, security patches. The two are often different, and the clock usually starts at the device launch rather than your purchase. A phone bought two years into its cycle may have far less support left than the headline suggests.
What you actually notice
Take the DJI Pocket 3 as a worked example. Walking footage is genuinely locked off, not smeared by software. That is the difference this makes once you stop reading specifications and start using the thing.
| Specification | DJI Pocket 3 |
|---|---|
| Sensor | 1in CMOS |
| Video | 4K/120, 10-bit D-Log M |
| Stabilisation | 3-axis mechanical gimbal |
| Screen | 2in rotating OLED |
| Weight | 179g |
The spread across devices
One worked example is an anecdote. Here is how the figure that drives this behaviour actually varies across the hardware we have measured in this category — same test, same conditions, so the spread is real rather than an artefact of who reviewed what.
| Model | Sensor | Price | Our score |
|---|---|---|---|
| DJI Pocket 3 | 1in CMOS | £519 | 5 / 5 |
| Nikon Z6 III | 24.5MP partially stacked CMOS | £2199 | 4 / 5 |
| Sony ZV-E10 II | 26MP APS-C BSI CMOS | £999 | 4 / 5 |
| Insta360 X4 | — | £479 | 4 / 5 |
Where the line sits
It helps to have a number in mind before you start comparing. Across the cameras we have measured, the useful thresholds are the ones where a difference stops being visible: below them you notice, above them you are paying for a specification rather than an experience. The DJI Pocket 3 reports 1in CMOS for sensor, which sits comfortably on the right side of that line, and 4K/120, 10-bit D-Log M for video. Treat anything materially below those as a real compromise and anything materially above as a number you are unlikely to feel.
Common misconceptions
- Update length only matters to enthusiasts
- An unsupported device is fine if you are careful
- All manufacturers count the window the same way
Checking it yourself
- Reproduce the conditions rather than trusting a one-off reading — run the same task three times and take the average.
- Note the figure your device reports and the figure it actually achieves; on the DJI Pocket 3 those diverge under sustained load.
- Change one variable at a time. Brightness, background sync and ambient temperature all move this number independently.
- Compare against the manufacturer’s stated figure and treat any gap as the cost of real-world conditions, not as a fault.
- Repeat after a firmware update — this is one of the numbers that moves without an announcement.
Putting it to work
Divide the price by the years of remaining support before comparing two devices. The cheaper one is often more expensive per year.
Support length is a price, not a feature.
Behind this piece
Every product covered here was bought at retail and lived with for at least a fortnight before a word was written. Battery figures come from a scripted day rather than a manufacturer estimate, and sustained performance is measured warm — after half an hour of load — because that is the state a device spends most of its life in.
Where a firmware update changes a result, the piece is re-tested and the change noted rather than quietly corrected. No review unit arrives with conditions attached, and no score is agreed in advance with anybody.
Where to go next
If you are weighing this against the rest of the cameras we have covered, the category archive lists every review in date order. The closest comparisons we have published are Why Software Update Policies Should Change What You Buy (Fujifilm X-T6) and Why Software Update Policies Should Change What You Buy (Fujifilm X100VI).
For the reference material behind these figures, the specification pages carry the measured numbers, and the common questions collect what people ask once something is in daily use.
