OnePlus 13 Review: The Fast One
Charging that still embarrasses the competition, wrapped around a phone that has quietly become very good at everything else.
Maya Okonkwo
Charging is the headline
Zero to sixty-two percent in fifteen minutes, and a full charge in thirty-four. Once you have lived with it, every other phone feels broken. Battery health after two weeks of daily fast charging showed no measurable degradation, though that is not a long-term verdict.
Display and build
A genuinely excellent panel with the best anti-reflective coating we have seen on a phone. The alert slider survives, and we remain glad of it.
Software
OxygenOS has drifted closer to ColorOS over the years, which will not please everyone, but it is fast and the animations are the best in Android.

How we tested
Every figure quoted above comes from the same protocol, run on every unit in this category. This one spent fourteen days as the reviewer’s only phone, SIM included. Screen at a metered 200 nits, adaptive refresh left on, the same twelve apps installed on every handset, and a fixed 5G network in the same building.
| What we measure | How |
|---|---|
| Screen-on time | A scripted day — four hours of mixed browsing, an hour of video, thirty minutes of camera, the rest idle — repeated three times and averaged. |
| Sustained performance | Twenty minutes of continuous load, reporting the figure at the end rather than the peak in the first ninety seconds. |
| Charging | From 2% to 100% with the fastest charger the manufacturer sells, at 22°C ambient, timed to the minute. |
| Camera | The same eighteen scenes on every phone — backlit portrait, indoor low light, moving subject — shot in the default mode with no editing. |
| Thermals | Surface temperature at the hottest point after the sustained run, measured with a contact probe. |
We deliberately do not report synthetic benchmark totals quoted in isolation, and any figure supplied by the manufacturer.
The honest caveat: Battery results are specific to our routine. A heavy camera user will see materially less screen-on time than these numbers suggest.
How it compares
The closest alternatives on price are Pixel 9 Pro and iPhone 16 Pro. All three have been through the same tests, so the figures below are directly comparable rather than collected from different reviews.
| Model | Price | Our score | Standout | Weak point |
|---|---|---|---|---|
| OnePlus 13 (this review) | £899 | 4 / 5 | Charging speed is in another league | Software has lost some of its identity |
| Pixel 9 Pro | £999 | 4 / 5 | The most consistent computational photography of any phone | The Tensor chip throttles under sustained load |
| iPhone 16 Pro | £1099 | 4 / 5 | The best sustained performance of any phone | Iterative to a fault |
Nothing at this price scored higher in our testing, which is the strongest argument for the OnePlus 13.
Is it worth the money?
At £899 the OnePlus 13 asks £19 more than the category average of £880, against an average score of 4.1 out of 5 across the smartphones we have tested. Its own 4 works out at roughly £225 per point. Paying above average for a below-average score only makes sense if readers who want charging speed is in another league describes you precisely.
If the budget is the binding constraint, the Galaxy A56 at £399 is the floor we would still recommend — below that the compromises stop being ones you can live with.
Living with it
Two weeks in, the figure that stopped mattering was display — 6.82in LTPO AMOLED, 120Hz, 3168 x 1440 is more than adequate and you forget about it by the third day. What kept surfacing instead was that software has lost some of its identity, which is easy to shrug off in a spec comparison and harder to ignore at 6pm on a Friday. On the other side, charging speed is in another league turns out to be the sort of detail you only appreciate after living with the alternative.
What we liked
- Charging speed is in another league
- Huge battery
- Superb display coating
- Alert slider
What we did not
- Software has lost some of its identity
- Camera processing is inconsistent shot to shot
Verdict
If you value charging speed and battery life above all else, nothing else comes close.
Score: 4 / 5 · £899 as reviewed (256GB)
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 smartphones we have covered, the category archive lists every review in date order. The closest comparisons we have published are OnePlus 13 vs Galaxy A56: Is the OnePlus 13 Worth £500 More? and OnePlus 13 vs Pixel 9a: Is the OnePlus 13 Worth £400 More?.
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.
