Highlights & Review Of Vivo x300 Ultra

Display Review:

The Vivo X300 Ultra features a 6.82-inch 2K LTPO AMOLED display with 1440 × 3168-pixel resolution, 1–144Hz adaptive refresh rate, and up to 4,500 nits peak brightness, along with Dolby Vision, HDR10+, and 2,160Hz PWM dimming for reduced eye strain. The Samsung Galaxy S26 Ultra uses a larger 6.9-inch QHD+ Dynamic LTPO AMOLED 2X panel with 3120 × 1440-pixel resolution, 1–120Hz adaptive refresh rate, and up to 2,600 nits peak brightness, plus Samsung’s Gorilla Glass Armor 2 anti-reflective coating and a unique Privacy Display mode that narrows viewing angles to block side-glances.

The Apple iPhone 17 Pro Max offers a 6.9-inch Super Retina XDR OLED with 2868 × 1320-pixel resolution, 1–120Hz ProMotion adaptive refresh rate, and up to 3,000 nits peak brightness for outdoor use, plus HDR10, Dolby Vision, and 1,000 nits typical indoor brightness. The Xiaomi 17 Ultra leads in size with a 6.9-inch 1.5K LTPO AMOLED at 2608 × 1200 pixels, 1–120Hz adaptive refresh rate, and up to 3,500 nits peak brightness, plus Dolby Vision, HDR10+, and 2,160Hz PWM dimming.

On paper, the Vivo X300 Ultra’s 4,500-nit peak and 2K 144Hz LTPO AMOLED give it the strongest outdoor visibility, smoothness, and efficiency potential, while the Galaxy S26 Ultra counters with its QHD+ resolution, Gorilla Glass Armor 2, and Privacy Display for enhanced security in public spaces. The iPhone 17 Pro Max’s 3,000-nit peak and Apple-tuned Super Retina XDR panel offer excellent color accuracy and HDR performance, and the Xiaomi 17 Ultra’s large 6.9-inch panel with 3,500-nit brightness provides a strong balance of size and visibility for multimedia consumption.

For Pakistani buyers at PKR 460,000, the Vivo X300 Ultra’s 6.82-inch 2K 144Hz LTPO AMOLED and 4,500-nit peak make it a top-tier multimedia and gaming display, while the Samsung Galaxy S26 Ultra at PKR 450,000 justifies its similar price with QHD+ resolution, anti-reflective glass, and privacy features. The Apple iPhone 17 Pro Max at PKR 465,000 and Xiaomi 17 Ultra at PKR 470,000 provide bright, sharp panels, with the iPhone 17 Pro Max leading in color accuracy and ecosystem integration, and the Xiaomi 17 Ultra offering the largest 6.9-inch display with competitive brightness and LTPO efficiency.

Verdict: The Vivo X300 Ultra is the best choice for buyers who want a large 6.82-inch 2K 144Hz LTPO AMOLED with 4,500 nits peak brightness at PKR 480,000, the Samsung Galaxy S26 Ultra leads in resolution and privacy features with its 6.9-inch QHD+ Dynamic LTPO AMOLED 2X and Gorilla Glass Armor 2, while the Apple iPhone 17 Pro Max and Xiaomi 17 Ultra suit users who prefer either Apple’s color-accurate Super Retina XDR panel or a large 6.9-inch 1.5K 120Hz LTPO AMOLED with strong brightness and Dolby Vision support.

Processor Review:

The Vivo X300 Ultra is powered by the Qualcomm Snapdragon 8 Elite Gen 5 (3nm) chipset with a 2+6 core layout (2×4.6GHz Oryon V3 Phoenix L + 6×3.62GHz Oryon V3 Phoenix M) and an Adreno 840 GPU, scoring approximately 4,065,000–4,085,000 points on AnTuTu v11 in third-party testing. The Samsung Galaxy S26 Ultra uses a factory-overclocked Snapdragon 8 Elite Gen 5 for Galaxy (3nm) with similar core configuration, achieving roughly 3,851,000 points on AnTuTu v11.

The Apple iPhone 17 Pro Max relies on the Apple A19 Pro (3nm) with 6-core CPU and 6-core GPU, posting about 2,400,000–2,600,000 points on AnTuTu v11 depending on variant and test conditions. The Xiaomi 17 Ultra sits between them with the standard Snapdragon 8 Elite Gen 5 (3nm), scoring approximately 3,740,000–4,110,000 points on AnTuTu v11 depending on tuning and thermal management.

On raw performance, the Vivo X300 Ultra’s Snapdragon 8 Elite Gen 5 leads this group by a clear margin in most real-world tests, outscoring the Galaxy S26 Ultra’s for Galaxy variant by roughly 200,000–300,000 AnTuTu points, while the Xiaomi 17 Ultra’s identical chipset delivers nearly identical performance with minor tuning differences. The iPhone 17 Pro Max’s A19 Pro shows strong single-core CPU results in Geekbench, but it still trails the Snapdragon 8 Elite Gen 5 implementations in multi-core and GPU-heavy sustained gaming and heavy multitasking headroom on AnTuTu v11.

For Pakistani buyers, the Vivo X300 Ultra at PKR 480,000 delivers flagship-tier performance that clearly outclasses the iPhone 17 Pro Max’s A19 Pro at PKR 465,000, justifying its higher price for users who prioritize peak Android speed. The Samsung Galaxy S26 Ultra at PKR 450,000 and Xiaomi 17 Ultra at PKR 470,000 offer near-flagship performance with the same chipset family, making them strong picks for users who want high scores at varying price points.

Verdict: The Vivo X300 Ultra leads in raw performance with its Snapdragon 8 Elite Gen 5 and ~4.07M–4.09M AnTuTu v11 score, the Xiaomi 17 Ultra is a close second with ~3.74M–4.11M, the Samsung Galaxy S26 Ultra sits third with ~3.85M, and the Apple iPhone 17 Pro Max is the performance laggard with ~2.4M–2.6M despite its higher price.

Ram & Memory Review:

The Vivo X300 Ultra comes in a 16GB + 512GB configuration with LPDDR5X RAM and UFS 4.0 storage, and it does not support any memory-card expansion. The Samsung Galaxy S26 Ultra offers 12GB + 512GB with LPDDR5X RAM and UFS 4.0 storage, but it lacks a microSD slot as well. The Apple iPhone 17 Pro Max matches this with 12GB + 256GB of unified memory and NVMe storage, though like the X300 Ultra and S26 Ultra, it omits expandable storage.

The Xiaomi 17 Ultra provides a more generous 16GB + 512GB setup with LPDDR5X RAM and UFS 4.0 storage, and it also does not support microSD expansion.

On paper, the Vivo X300 Ultra and Xiaomi 17 Ultra benefit from 16GB RAM compared with the Galaxy S26 Ultra and iPhone 17 Pro Max’s 12GB, which improves sustained multitasking, app reloads, and heavy workload handling. All four phones use top-tier UFS 4.0 or equivalent NVMe storage, so app launch times, large file transfers, and overall storage responsiveness are closely matched. The lack of microSD support across the board means users must rely solely on their 256–512GB internal capacity, which is ample for most buyers but may require more frequent management for those with extensive media libraries.

For Pakistani buyers, the Vivo X300 Ultra at PKR 480,000 and Xiaomi 17 Ultra at PKR 470,000 offer flagship-tier 16GB + 512GB memory performance, while the Galaxy S26 Ultra at PKR 450,000 provides 12GB + 512GB at a slightly lower price, making it a strong value pick for users who prioritize display and camera over maximum RAM. The iPhone 17 Pro Max at PKR 465,000 offers 12GB + 256GB, which may feel limiting for power users who store large video libraries locally.

Verdict: The Vivo X300 Ultra and Xiaomi 17 Ultra lead in raw memory capacity with 16GB + 512GB, making them the best choices for heavy multitaskers and content creators, while the Samsung Galaxy S26 Ultra offers 12GB + 512GB at a competitive price, and the Apple iPhone 17 Pro Max sits behind with 12GB + 256GB, making it less suitable for users who need maximum storage and RAM headroom.

Cameras Review:

The Vivo X300 Ultra uses a 200MP Sony LYT-901 main camera with f/1.85 aperture, gimbal OIS, and PDAF, paired with a 200MP Samsung HP0 periscope telephoto (3.7x optical zoom, f/2.67, OIS) and a 50MP Sony LYT-818 ultrawide lens with OIS. It records rear video up to 8K@30fps, 4K@120fps on all three rear cameras, and 10-bit Log with Dolby Vision HDR, while the front 50MP camera supports 4K@60fps and 1080p@30fps.

The Samsung Galaxy S26 Ultra features a 200MP Samsung ISOCELL HP2 main sensor with f/1.4 aperture, OIS, and multi-directional PDAF, plus a 50MP 5x periscope telephoto with OIS, a 50MP ultrawide, and a 10MP 3x telephoto with OIS. It records rear video up to 8K@30fps, 4K@120fps on all cameras, and 10-bit HDR10+, with the front 12MP camera capped at 4K@60fps and 1080p@30fps.

The Apple iPhone 17 Pro Max offers a 48MP Fusion main camera with f/1.78 aperture, sensor-shift OIS, a 48MP 5x periscope telephoto with 3D sensor-shift OIS, and a 48MP ultrawide lens, recording rear video up to 4K@120fps (main only), 4K@60fps on all cameras, and 10-bit Dolby Vision HDR, with the front 24MP camera at 4K@60fps and 1080p@30fps.

The Xiaomi 17 Ultra is equipped with a 50MP 1-inch OV50X main sensor with f/1.7 aperture, OIS, a 200MP 3.2–4.3x continuous optical zoom periscope telephoto with OIS, and a 50MP ultrawide lens, plus a 32MP front camera with autofocus. It records rear video up to 8K@30fps, 4K@120fps, and 1080p@240/480/960/1920fps, plus 4K Log recording, with front video at 4K@60fps and 1080p@60fps.

On paper, the Vivo X300 Ultra’s dual 200MP main and telephoto sensors, gimbal OIS, and 4K@120fps 10-bit Log on all rear cameras give it a clear advantage for professional video and zoom photography, while the Galaxy S26 Ultra’s f/1.4 main aperture and 8K@30fps across all cameras make it a strong all-round flagship. The iPhone 17 Pro Max’s 48MP triple-camera system with sensor-shift OIS and 4K@120fps (main only) offers excellent stabilization and color accuracy, but it lacks 8K recording and high-resolution telephoto compared to the X300 Ultra and Xiaomi 17 Ultra. The Xiaomi 17 Ultra’s 200MP continuous optical zoom periscope and 8K@30fps video position it as a strong telephoto and video contender, while its 1-inch main sensor provides superior low-light performance.

For Pakistani buyers, the Vivo X300 Ultra at PKR 460,000 offers a top-tier 200MP + 200MP camera system with 8K@30fps and 4K@120fps 10-bit Log video, making it the best choice for creators and photography enthusiasts. The Galaxy S26 Ultra at PKR 450,000 provides a reliable 200MP OIS system with f/1.4 aperture and 8K@30fps across all cameras, while the iPhone 17 Pro Max at PKR 465,000 and Xiaomi 17 Ultra at PKR 470,000 target users who value either Apple’s color-accurate 48MP system with 4K@120fps or high-resolution telephoto and 8K recording.

Verdict: The Vivo X300 Ultra leads in camera versatility with its dual 200MP main and telephoto sensors, gimbal OIS, and 4K@120fps 10-bit Log video, the Samsung Galaxy S26 Ultra offers the brightest f/1.4 main aperture and 8K@30fps across all cameras, the Xiaomi 17 Ultra provides a strong 200MP continuous optical zoom periscope system with 8K@30fps recording, and the Apple iPhone 17 Pro Max sits behind with a balanced 48MP triple-camera system and 4K@120fps (main only) but no 8K or high-resolution telephoto.

Battery Review:

The Vivo X300 Ultra is equipped with a 6,600mAh silicon-carbon battery and supports 100W wired fast charging, 40W wireless charging, and reverse wireless charging, reaching 0–100% in around 30–35 minutes under test conditions.

The Samsung Galaxy S26 Ultra uses a smaller 5,000mAh battery but compensates with 60W wired fast charging, 25W Qi2 wireless charging, and 4.5W reverse wireless charging, achieving 0–100% in about 50–55 minutes, though it lacks the raw capacity of the X300 Ultra.

The Apple iPhone 17 Pro Max features a 4,823mAh battery with 45W wired fast charging (adapter sold separately), 25W MagSafe wireless charging, and 15W Qi2 wireless, hitting 0–100% in roughly 70–80 minutes, plus strong ecosystem integration

. The Xiaomi 17 Ultra sits between them with a massive 6,800mAh battery and 90W wired + 50W wireless + 10W reverse charging, reaching 0–100% in about 40–45 minutes, offering the largest capacity in this group.

In endurance terms, the Xiaomi 17 Ultra’s 6,800mAh cell gives it the longest potential screen-on time, especially for heavy users, while the Vivo X300 Ultra’s 6,600mAh pack still offers strong all-day life with faster 100W wired and 40W wireless charging.

The Galaxy S26 Ultra’s 5,000mAh battery is mid-pack, and the iPhone 17 Pro Max’s 4,823mAh battery is the smallest here, with its 45W wired charging significantly slower than the 90–100W systems on the Vivo and Xiaomi flagships, making it less suitable for users who prioritize rapid top-ups and maximum endurance.

For Pakistani buyers, the Vivo X300 Ultra at PKR 480,000 delivers excellent battery life with its 6,600mAh cell and fastest 100W wired + 40W wireless charging in this group, while the Galaxy S26 Ultra at PKR 450,000 offers balanced endurance with 5,000mAh + 60W wired + 25W wireless but slower full-charge times.

The iPhone 17 Pro Max at PKR 465,000 and Xiaomi 17 Ultra at PKR 470,000 provide strong 4,823–6,800mAh capacities with 45–90W wired and 25–50W wireless charging, making the Xiaomi 17 Ultra the best value pick for users who prioritize battery life and fast charging at a competitive price.

Verdict: The Xiaomi 17 Ultra is the battery endurance champion with 6,800mAh + 90W wired + 50W wireless, the Vivo X300 Ultra leads in balanced endurance and charging speed with 6,600mAh + 100W wired + 40W wireless, the Samsung Galaxy S26 Ultra offers strong 5,000mAh + 60W wired + 25W wireless, and the Apple iPhone 17 Pro Max sits behind with 4,823mAh + 45W wired + 25W wireless, making it the least suitable for heavy users and fast-charging enthusiasts.

Final Verdict :

1. Vivo X300 Ultra – Best Overall Flagship

Price: PKR 480,000
Strengths: The X300 Ultra offers the most balanced flagship experience with its 200MP + 200MP dual main/telephoto camera system, gimbal OIS, 4K@120fps 10-bit Log video on all rear cameras, 6,600mAh battery with 100W wired + 40W wireless charging, and a 2K 144Hz LTPO AMOLED display. It outperforms the iPhone 17 Pro Max in camera versatility, battery life, and charging speed, while matching or exceeding the Galaxy S26 Ultra in key areas at a competitive price.

2. Samsung Galaxy S26 Ultra – Best Display & Ecosystem

Price: PKR 450,000
Strengths: The S26 Ultra excels with its 6.9-inch 2K 120Hz LTPO AMOLED display, 200MP f/1.4 main camera with 8K@30fps across all cameras, 5,000mAh battery with 60W wired + 25W wireless charging, and strong One UI 8 ecosystem integration. It is the best value pick for users who prioritize display quality, camera brightness, and Samsung’s software support, though it falls behind the X300 Ultra in battery capacity and charging speed.

3. Xiaomi 17 Ultra – Best Battery & Telephoto Zoom

Price: PKR 470,000
Strengths: The Xiaomi 17 Ultra leads in raw battery capacity with its 6,800mAh cell, 90W wired + 50W wireless charging, and 200MP continuous optical zoom periscope telephoto system with 8K@30fps video.
