The Indian laptop market has become extremely competitive in the last few years, with popular brands such as HP, Lenovo, ASUS, and Acer providing a lot of models at every budget level. But an unlikely contender has been making steady inroads—Infinix, famous for its affordable smartphones, has now gone further into the laptop arena with the XBOOK B15. Aggressively priced at a mere ₹30,990, this 15.6-inch notebook promises high performance, ruggedness, and premium-like features at a price point that beats the competition.
Is Infinix XBOOK B15 worth purchasing in 2025, then? Let’s go deep into its design, screen, performance, battery life, advantages & disadvantages, and find out who this laptop is ideal for.
Design & Build Quality
The first thing you notice about the XBOOK B15 is that it doesn’t feel like a cheap, budget laptop. Infinix has given it an aluminum alloy lid, slim bezels measuring just 3.75 mm, and a weight of around 1.59 kg. At 17.65 mm thickness, it isn’t an ultrabook, but it strikes a good balance between sturdiness and portability.
What makes it stand out among the other laptops in this category is its MIL-STD-810H certification. It is tested for longevity in drops, shocks, and temperature changes, so it is a great option for students and business professionals who are on the move frequently.
The keyboard is a full-sized keyboard that offers a numeric keypad, something that most students and professionals working from home will find useful. It also offers backlighting, a feature not often seen in laptops priced under ₹35,000. The trackpad is reasonable in size, though not as high-end compared to more expensive laptops.
The other nice touch is the 1080p webcam that comes with a privacy shutter, something that’s highly topical in this age of hybrid work and online education.
Display—Big Screen, But Not the Best for Creatives
The Infinix XBOOK B15 comes with a 15.6-inch Full HD IPS panel (1920 × 1080 resolution) offering a 178° viewing angle. The slim bezels make it feel more immersive, and for watching movies, streaming content, or general office use, the display is more than adequate.
But there’s a caveat. Infinix boasts 100% sRGB coverage in certain international versions, but the Indian variant is capped at about 45% NTSC color gamut with 250–300 nits brightness. That translates to less punchy and more muted colors, so not so great for pro video editors, graphic designers, or photographers who need good-quality screens.
Short version: Perfect for everyday applications, but not the best for color-sensitive tasks.
Performance—Ryzen Power without the Burden
Infinix has taken the smart decision of providing the XBOOK B15 with AMD Ryzen U-series processors. Based on the model, you can opt for:
- Ryzen 5 5500U
- Ryzen 5 7430U
- Ryzen 7 5825U
These CPUs are thoroughbreds in the thin-and-light notebook market. For everyday activities such as browsing, office applications, coding, and multitasking, the performance is seamless and effective. Even light video editing and content creation are within reach, courtesy of Ryzen’s robust multi-core performance.
The laptop features 8 GB or 16 GB DDR4 RAM (up to 64 GB in some models) and NVMe SSD storage options from 256 GB to 1 TB. The SSD provides for speedy boot-up and fast app opening. Storage can be doubled to 2 TB, which is great at this price level.
For graphics, all you get is integrated Radeon Vega graphics, so casual gaming like CS:GO or Valorant is doable on low settings, but don’t count on it being able to play AAA games or heavy 3D rendering.
Battery & Charging
The Infinix XBOOK B15 comes with a 50 Wh battery, which will last you about 6–8 hours of mixed use (office apps, browsing, streaming). For a 15.6-inch laptop, this is pretty normal.
It has a 65 W Type-C charger, which charges the laptop up to around 50% in less than an hour. The USB-C convenience also allows you to use third-party chargers or even power banks with PD support.
This makes it a sturdy buddy for students sitting through long lectures or office-goers who are always on the move.
Connectivity & Ports
Port availability is another XBOOK B15 strength. While some thin ultrabooks sacrifice ports, Infinix offers you:
- 1 × USB-C (full function: charging, data, display)
- 1 × USB-C (data only)
- 1 × USB 3.2 Type-A
- 1 × USB 2.0
- 1 × HDMI 1.4
- 1 × RJ-45 Ethernet port
- 1 × TF/SD card slot
- 1 × 3.5 mm headphone jack
This diversity allows you to plug in external monitors, projectors, peripherals, and storage devices without the use of dongles. RJ-45 (LAN port) availability is particularly convenient for hostel students or gamers using wired internet for constant performance.
Audio & Webcam
The XBOOK B15 includes dual 1.5W speakers that are tuned with DTS audio processing. Although they aren’t the most powerful in the segment, they produce clear enough audio for films, video calls, and occasional music listening. In order to get a better experience, most would still opt for headphones or external speakers.
The 1080p webcam is a highlight at this price range. With a physical privacy shutter, it makes video calling significantly better than the typical 720p webcams on budget laptops
Pros & Cons
Pros
- Durable construction with MIL-STD-810H ruggedness
- Value-for-money price of ₹30,990 and upwards
- Ryzen processors provide consistent performance
- Upgradable RAM & storage
- Numeric keypad on backlit keyboard
- 1080p webcam & privacy shutter
- Complete set of ports, including LAN & USB-C
Cons
- Screen capped at 45% NTSC in Indian variant
- Not ideal for serious gaming or GPU-intensive tasks
- Speakers would be louder
- Infinix’s after-sales service network is still expanding
Who Should Purchase the Infinix XBOOK B15?
The Infinix XBOOK B15 is obviously made for:
- Students who need an affordable laptop for classes, projects, and online studies
- Office workers who require a solid computer for work, video conferencing, and multitasking
- Casual users looking for a big screen, sturdy build, and day-to-day performance without an outlay of ₹50,000+
But if you are:
- A creative professional (designer, video editor, photographer) requiring color-accurate screens
- A gamer requiring high frame rates and dedicated graphics
- A traveler looking for ultra-lightweight notebooks
Then you might consider alternatives from the ASUS VivoBook, Lenovo IdeaPad Slim, or HP Pavilion series.
Final Verdict
Priced at ₹30,990, the Infinix XBOOK B15 is an unbelievable value. It packs in solid Ryzen performance, a rugged build, contemporary connectivity, and more thoughtful touches such as a 1080p webcam and backlit keyboard for a price that most competitors can’t beat.
Yes, the screen is its weakest point for people who require precise colors, and it won’t appeal to gamers who want huge amounts of graphics processing power. But for its intended group—students, office employees, and general users—it’s quite possibly one of the top laptops costing less than ₹35,000 in 2025.
Infinix has done it again, showing that budget notebooks no longer need to feel or look cheap.
