Performance Review
The Power of Dimensity 7300
The heart of the iQOO Z10x 5G is the MediaTek Dimensity 7300. Built on a flagship-grade 4nm process, this octa-core processor is a significant step up from its predecessors. In our testing, the device handled day-to-day tasks like browsing, social media scrolling, and video streaming with absolute ease. The 6GB of RAM is well-optimized, and thanks to iQOO’s extended RAM technology, the phone can allocate extra storage as virtual memory to keep more apps open in the background.
For gamers, the Dimensity 7300 is a capable companion. While it isn't a flagship "gaming" chip, it runs popular titles like BGMI (Battlegrounds Mobile India) and Call of Duty: Mobile at high frame rates with stable performance. The 120Hz refresh rate display ensures that the visuals remain fluid, which is crucial for competitive gaming. Furthermore, the inclusion of a specialized liquid cooling system helps in maintaining thermal stability, preventing the device from throttling even during hour-long sessions.
Unrivaled Battery Endurance
The standout feature of the iQOO Z10x 5G is undoubtedly its 6500 mAh battery. In an era where 5000 mAh has become the standard, iQOO has gone the extra mile. For a typical user, this phone is easily a three-day device. For heavy users who consume hours of video content or play games, it comfortably lasts through a full day with plenty of juice left for the next morning. The 44W FlashCharge is efficient; considering the massive size of the battery, it manages to charge the device from 0 to 50% in a reasonable amount of time, ensuring you aren't stuck near a power socket forever.
Display and Multimedia
The 6.72-inch FHD+ display is bright and vibrant. While it is an LCD panel rather than AMOLED, the 120Hz refresh rate and 1000 nits peak brightness (HBM) make it one of the better LCDs in this price bracket. The colors are punchy, and the contrast levels are respectable for watching Netflix or YouTube. The single bottom-firing speaker is surprisingly loud, though it lacks the depth of a dual-stereo setup found in more expensive models.
Military-Grade Build Quality
Rarely do we see "Military-Grade Durability" mentioned for a phone priced under ?15,000. iQOO has reinforced the internal structure and used high-strength glass to ensure the Z10x can withstand accidental drops. It also carries an IP54 rating, providing protection against dust and occasional water splashes. The Ultramarine color has a premium matte finish that resists fingerprints, making the device look clean even after extended use.

Customer Feedback
With a rating of 4.4 out of 5, the general consensus among buyers is overwhelmingly positive. Here is a summary of what users are saying:
What Users Loved:
- Battery Life: Almost every reviewer mentions the insane battery backup. Users are delighted that they no longer need to carry power banks.
- Performance: The Dimensity 7300 is praised for being lag-free and efficient. Users have noted that the phone stays cool even during multitasking.
- Durability: Several users have appreciated the robust feel of the phone, feeling more confident using it without a bulky case.
- Design: The Ultramarine color is a hit, with many users describing it as "sophisticated" and "premium."
Areas for Improvement:
- Camera Performance: While the 50MP main camera takes great daylight shots, low-light performance is average. The lack of an ultra-wide lens is a missed opportunity for some.
- Charging Speed: While 44W is fast, some users wished for 67W or 80W charging given the massive battery capacity.
- Software Bloatware: Funtouch OS 14 comes with some pre-installed apps, although most can be uninstalled or disabled.
Price Analysis
At ?14,999, the iQOO Z10x 5G is positioned in the "sweet spot" of the Indian smartphone market. Let’s look at the value proposition compared to the competition:
Typically, phones in this price range offer 5000 mAh batteries and either the Snapdragon 6 Gen 1 or the older Dimensity 6020/7020 chips. By offering the Dimensity 7300 and a 6500 mAh battery, iQOO has effectively disrupted the hierarchy. You are getting a chip that is usually found in phones costing ?20,000 to ?25,000, paired with a battery that has no real rival in this segment.
When you factor in the 5G capabilities, the high refresh rate display, and the reinforced durability, the price of ?14,999 feels like a bargain. It is an ideal choice for students, delivery professionals, and long-distance travelers who need a phone that won't die on them in the middle of the day.

Final Verdict
The iQOO Z10x 5G (Ultramarine, 6GB RAM, 128GB Storage) is a specialized powerhouse. It doesn't try to be a jack-of-all-trades; instead, it masters the two most important aspects for most users: Battery Life and Reliable Performance.
If you are looking for the best camera phone in this price range, you might want to look elsewhere as the lack of an ultra-wide sensor is noticeable. However, if your priorities are uninterrupted usage, smooth gaming, and a phone that can survive a few tumbles, there is simply no better option under ?15,000 right now.
Who should buy the iQOO Z10x 5G?
- Power Users: People who use their phones for 8-10 hours of screen-on-time daily.
- Budget Gamers: Players who want a stable 5G gaming experience without overheating issues.
- Outdoor Workers: Those who need military-grade durability and a battery that lasts through long shifts.
- Students: Anyone looking for a long-term device that offers great value for their savings.
In conclusion, the iQOO Z10x 5G is a highly recommended device. It successfully balances cutting-edge 4nm processing power with a massive battery, all wrapped in a durable and stylish Ultramarine chassis. At ?14,999, it is a formidable contender for the best budget 5G smartphone of the year.
