The Huawei P40 is a compact, camera-focused Android 10 smartphone built around a 6.1" 2340×1080 display and HiSilicon Kirin 990 5G chipset. It was offered with 6,144 MB or 8,192 MB of RAM and 128 or 256 GB of storage, and its headline spec is a 50 MP main camera. The device sits in the premium-to-upper-mid range of Huawei's P-series hardware family and targets users who prioritise imaging hardware and flagship-class silicon.
This review synthesises public benchmark medians and lab reviews: user-submitted UL Solutions benchmark medians (including 3DMark Wild Life), NanoReview aggregated scores, and independent lab reporting from Notebookcheck and The Informr. Where available we use median benchmark data (UL Solutions) and recorded measurement points such as maximum surface temperature and stability metrics reported by those sources.
High level: the P40 delivers notable imaging hardware and competitive single-run GPU numbers (3DMark Wild Life median 3276, graphics test ~19 FPS) and ships with modern connectivity via the Kirin 990 5G. It is hampered, however, by inconsistent sustained performance — a Wild Life stability of 44% and reported max surface temperature of 44.1°C indicate thermal throttling under prolonged load — and it registers low recent popularity in the UL dataset.
Flagship single-run speed, inconsistent sustained load performance
The P40's HiSilicon Kirin 990 5G chipset produces a median 3DMark Wild Life score of 3276 with a graphics test result of roughly 19 FPS according to UL Solutions median submissions. Notebookcheck's benchmarking also identified the phone as 'very fast' in single-run scenarios, confirming solid peak performance for everyday apps and short gaming sessions.
Sustained performance is a concern: UL Solutions reports a Wild Life stability of 44%, meaning median runs show significant frame-rate drops under prolonged load. Expect higher initial performance followed by throttling during extended gaming or heavy GPU workloads.
50 MP main camera is the headline feature
Huawei equipped the P40 with a 50 MP main sensor — a clear specification highlight in the product sheet and repeatedly noted in lab reviews for imaging capability. Notebookcheck's review title explicitly describes the P40 as having a 'great camera', reflecting the device's strength in still photography.
While this review relies on the provided spec (50 MP) and lab impressions, benchmark sources focused on system performance rather than a detailed quantitative camera score. The hardware spec and independent commentary indicate the P40's camera is among its strongest selling points.
Thermal throttling affects sustained performance; battery figures vary in public benchmarks
UL Solutions' aggregated data shows a maximum surface temperature of 44.1 °C in public submissions, paired with a Wild Life stability of 44%. Those two figures together point to thermal constraints: the device heats under load and reduces clocking to protect hardware, which explains the low stability metric.
Battery life in the UL dataset is presented as a median of user-submitted runs and is noted to be highly sensitive to screen brightness; the benchmarking service recommends calibrating to 200 cd/m² for lab tests. The public-submitted nature of the data means battery-life scores vary widely for the P40, so expect differing results in real-world usage depending on brightness and workload.
Compact 6.1" 2340×1080 display with flagship-class fit-and-finish
The P40 uses a 6.1-inch panel at 2340 × 1080 resolution — a pixel density that supports sharp text and media playback on a relatively compact footprint. The display resolution and size are consistent with a premium compact phone design.
Lab sources in the brief highlight overall strong hardware construction in the P-series; combined with the P40's compact 6.1" screen, the device targets users who want flagship specs without a phablet-sized chassis. Specific brightness and panel type figures were not provided in the available dataset.
Adequate RAM and storage options for the platform
Huawei offered the P40 with 6,144 MB or 8,192 MB of RAM and 128 or 256 GB of internal storage, which aligns with typical flagship configurations at launch and provides sufficient headroom for multitasking and large photo/video libraries.
Storage and RAM choices give users clear upgrade paths between base and higher-capacity SKUs; the benchmark datasets referenced focus on system and GPU performance rather than storage throughput metrics.
Pros & Cons
- ✅ 50 MP main camera — primary hardware highlight cited by lab reviews

- ❌ UL Solutions popularity metric listed as 0.0% in recent submissions
- ❌ Shipped with Android 10 (per spec data) while newer OS versions exist
How It Compares to the Competition
- Samsung Galaxy S20 — More mature app ecosystem and frequent updates; comparable flagship performance but different ecosystem trade-offs compared to Huawei's P40.
- Google Pixel 4a 5G — Smaller-camera-focused Pixel offers cleaner software update cadence and strong computational photography despite lower raw camera megapixel count.
- OnePlus 8 — Similar-era flagship performance with generally better sustained thermal behaviour on some SKUs; OnePlus targets smoother sustained performance.
- Huawei P40 Pro — Within Huawei's own lineup the P40 Pro expands on battery, camera and thermal design, offering better sustained performance at the cost of a larger footprint.
Who Should Buy This & Who Should Skip It
Buy it if: Buy the Huawei P40 if you prioritise a 50 MP main camera, compact 6.1" 2340×1080 hardware and flagship single-run performance from the Kirin 990 5G, and if you accept that sustained gaming will be constrained by thermal throttling. It's a fit for photographers and users who want a smaller flagship device.
Skip it if: Skip the P40 if you need stable sustained performance for long gaming sessions or GPU-heavy workloads—its Wild Life stability of 44% and surface temps up to 44.1 °C suggest significant throttling. Also consider other models if you require a newer Android baseline than Android 10.
