At 9 pm, light from a café falls across a table. The phone says 200 MP, the seller promised “incredible night photos”, and the image comes out noisy, with a soft face and a street lamp turned into a white halo.
The problem is not the megapixel count. Night photography depends mainly on how much light the sensor receives, how it is stabilised and how the processing combines several frames. Five things matter. Here they are, followed by four phones sold in Algeria at their lowest listed prices on 7 November 2026.
What changes a night photo
Sensor size. A one-inch sensor gathers more light than a smaller sensor at the same resolution. That is why a 50 MP sensor on a large surface can beat a 200 MP sensor on a small one.
Aperture. The wider it is, the more light reaches the sensor. An f/1.6 or f/1.7 lens helps, but it cannot compensate for a tiny sensor.
Optical stabilisation. OIS allows a longer handheld exposure. Without it, the slightest shake becomes blur.
Processing. Good software stacks several frames, reduces noise and keeps faces sharp. Aggressive night mode can also smooth textures and invent detail.
Optical zoom. For a monument or a shop sign, a 3x or 5x periscope avoids digital zoom, which destroys detail.
Four phones, four approaches
| Phone | Lowest price | Main sensor | Zoom | Battery | Offers |
|---|---|---|---|---|---|
| Vivo X100 Ultra | DZD 135,000 | 50 MP, 1 inch | 200 MP periscope | 5,500 mAh | 1 |
| Xiaomi 15 Ultra | DZD 142,000 | 50 MP, 1 inch | 200 MP periscope | 5,410 mAh | 6 |
| Huawei Pura 70 Ultra | DZD 159,000 | 50 MP, 1 inch | 50 MP tele, retractable lens | 5,200 mAh | 3 |
| Samsung Galaxy S25 Ultra | DZD 170,000 | 200 MP, 1/1.3 inch | 50 MP 5x | 5,000 mAh | 29 |
The prices are the lowest active offers at the time of the survey. They say nothing about stock, warranty or the exact model version. This comparison uses official specifications, not lab tests. A shop test remains the best check.
Vivo X100 Ultra: the most photo-focused option
The X100 Ultra pairs a one-inch main sensor with a 200 MP periscope. On paper, it is the most night-oriented combination of the four. Its DZD 135,000 starting price is the lowest, but the catalogue shows only one offer. Availability can therefore change quickly.

Xiaomi 15 Ultra: the most complete compromise
The 15 Ultra also uses a one-inch sensor and a 200 MP periscope, with Leica processing. It is newer than the Vivo, has a complete specification sheet and showed six offers in the survey. At DZD 142,000 it sits between the Vivo and the Huawei.
Xiaomi 15 Ultra
16GB RAM · 512GB · 6.73 · AMOLED
Huawei Pura 70 Ultra: the variable aperture
The Pura 70 Ultra relies on a one-inch sensor with a variable aperture and a lens that extends mechanically from the camera block. The result can be excellent in low light, but Huawei's software (EMUI or HarmonyOS, depending on the version) runs without Google services. Check your banking, delivery and messaging apps before choosing it.

Samsung Galaxy S25 Ultra: availability first
The S25 Ultra has a 200 MP main sensor that is smaller than the other three, but it compensates with strong processing, a 5x zoom and much wider availability: 29 offers in the survey. It is the easiest choice if you want to buy today with an identifiable service network.

The 200 MP trap
A 200 MP sensor can produce very detailed photos in daylight. At night, it often combines several pixels to gather more light and outputs a 12 or 12.5 MP image. The result of that combination matters, not the number on the box.
A small 200 MP sensor can therefore perform worse than a 50 MP one-inch sensor. Specification sheets do not replace a test, but they can rule out the simplest promises.
Six useful steps tonight
- Clean the lens with a dry cloth. One fingerprint is enough to create a halo.
- Tap the screen to focus on the face or the light, then lower the exposure if the scene is too bright.
- Hold the phone with both hands and press gently. Night mode takes several frames.
- Stay at 1x or use optical zoom. Digital zoom enlarges the noise.
- Avoid flash for street scenes. It flattens faces and creates hard shadows.
- Take three photos instead of one. Processing varies from frame to frame.
For a portrait in a café, ask the person to stay still for a second. For a bright shop sign, lower the exposure so the letters remain readable. For a landscape, rest the phone on a wall or a small tripod.
How to test in a shop
Ask to take a photo in a dark corner of the store, not only under the neon lights. Zoom into the image and look at noise, faces and light sources. Take the same scene with two models and compare on your own screen.
If the seller refuses the test, it is not automatically a bad shop, but you are buying a specification sheet rather than a result. For a tighter budget, our camera phones under DZD 50,000 guide offers other options.
What to remember
The best night phone is not the one with the highest megapixel count. It is the one where the sensor, lens and processing work together. The Vivo X100 Ultra and Xiaomi 15 Ultra are the most ambitious on paper. The Galaxy S25 Ultra is the easiest to find and repair. The Huawei Pura 70 Ultra will suit users who can live without Google services.
Compare offers on Mobilidz, then test a night photo before paying. One image taken in low light is worth more than ten promises at the counter.
