How we verified these figures
Nothing on this page is copied from a press release. Each unit spends two working weeks as a primary machine, on battery wherever possible. Display at 150 nits, keyboard backlight off, the manufacturer’s balanced power profile, and the same browser profile with thirty tabs restored on every machine.
| What we measure | How |
|---|---|
| Battery life | A looped workday script — document editing, video calls, browsing — run to shutdown, three times, averaged. |
| Sustained CPU | A thirty-minute all-core render, reporting the settled clock speed rather than the boost figure. |
| Fan noise | Measured at 50cm from the display hinge during that render, in a room with a 28dB floor. |
| Chassis heat | Palm rest and underside temperatures after the render, since that is where it is actually felt. |
| Display | Brightness and contrast from a colorimeter, at the panel’s native setting rather than a boosted HDR mode. |
We deliberately do not publish single-core burst scores, which almost nothing outside a benchmark actually produces. Sustained figures depend on ambient temperature. A warm room costs most thin laptops several percent.
How it compares in the category
A specification only means something next to the alternatives. These are the laptops we have measured under the same conditions.
| Model | Released | Price | Our score | Best for |
|---|---|---|---|---|
| Acer Aspire 14 AI | 2025 | £649 | 3 / 5 | Students who need a working machine rather than a nice one |
| ASUS Zenbook 14 OLED | 2025 | £1,099 | 4 / 5 | Windows users who want the MacBook Air experience |
| MacBook Air M4 | 2025 | £1,199 | 5 / 5 | Students, writers and anyone who works away from a socket |
| Framework Laptop 13 | 2024 | £1,399 | 4 / 5 | Anyone who intends to keep a laptop for six years or more |
| HP Spectre x360 14 | 2025 | £1,499 | 4 / 5 | Note-takers and anyone who sketches or annotates |
| ThinkPad X1 Carbon Gen 13 (this page) | 2025 | £1,649 | 4 / 5 | People who type for a living |
What the spec sheet leaves out
- Sustained performance — the display figure above is a capability, not a promise about what happens after twenty minutes
- How it behaves when warm, which is where most of the difference between similarly specified laptops actually lives
- Software support length, which decides how long this stays usable and appears on no specification sheet we have seen
- The thing we actually noticed most: it passes military drop testing at 1.09kg
What the numbers mean in use
Specifications describe capability, not experience. In practice the detail that mattered most was this: it passes military drop testing at 1.09kg. That is the sort of thing a table cannot capture.
Strengths on paper and in practice
- The best keyboard on any laptop
- A full port selection including USB-A and HDMI
- Excellent Linux support
Known limitations
- A merely adequate display
- Expensive for the specification
- A design that has not changed in years
Who this suits
This hardware is a good fit for people who type for a living.
Behind this page
This reference page is written from the same testing notes as the reviews it supports, and it is revised whenever the hardware or the software underneath it changes. Where a figure appears here it has been measured rather than quoted from a specification sheet.
If something on this page no longer matches what you are seeing, it is out of date rather than disputed — tell us and it gets checked again.
