Finding a good smartphone under ₹25,000 in 2026 has become increasingly difficult as prices continue to rise across every segment. While brands are trying to attract users with better displays, improved cameras, and premium designs, battery life still remains one of the most important deciding factors for many buyers. After all, a powerful smartphone means very little if it constantly needs to be charged.

This is where the iQOO Z11x 5G attempts to stand out. Starting at ₹22,999, the smartphone immediately grabs attention with its massive 7,200mAh battery, which is among the biggest available in this price segment. On paper, the battery specifications already look impressive, but real-world performance matters far more than numbers alone.After using the iQOO Z11x for several weeks as a daily driver, it became clear that battery endurance is the phone’s biggest strength. Whether it was social media usage, navigation, gaming, or streaming content, the phone consistently delivered reliable and long-lasting performance without creating battery anxiety.

Massive 7,200mAh Battery Steals the Spotlight 🔋❤️

The biggest highlight of the iQOO Z11x is undoubtedly its enormous 7,200mAh battery. In a market where most smartphones still offer 5,000mAh or 6,000mAh batteries, iQOO has pushed battery capacity to another level. However, simply having a large battery is not enough—the real challenge is optimization and efficient power management.

Thankfully, the iQOO Z11x handles this extremely well. During day-to-day usage, the phone consistently delivered impressive endurance regardless of workload. Casual tasks such as browsing social media, watching YouTube, chatting, and taking calls barely made a noticeable dent in the battery percentage. Even heavier tasks like navigation and gaming remained surprisingly power efficient.

What makes the battery experience feel even better is the consistency. The phone doesn’t suffer from excessive idle drain, meaning it holds charge effectively even when not actively being used. Over time, this creates a sense of reliability that many budget smartphones struggle to deliver.

PCMark Results Show Exceptional Endurance 🙌❤️

To measure battery performance under stress, the iQOO Z11x was tested using the PCMark battery benchmark, which simulates real-world workloads such as web browsing, document editing, video playback, and app usage continuously until the battery drains.The results were genuinely impressive. The device managed to last for more than 29 hours in the benchmark, which places it among the strongest battery performers in the sub-₹20,000 category. This level of endurance is extremely rare, especially considering the phone also supports a 120Hz display and 5G connectivity.These benchmark numbers are not just synthetic achievements—they closely reflect the phone’s real-world endurance. The iQOO Z11x feels designed for users who want to use their device heavily without worrying about finding a charger midway through the day.

Real-World Battery Usage Remains Excellent

Beyond benchmark testing, the real-world battery performance of the iQOO Z11x proved equally impressive. During regular daily usage, the device consistently lasted well beyond a single day and often stretched close to two days depending on workload.Video streaming performance was particularly impressive. During a 30-minute streaming session, the phone dropped only 3 percent battery, highlighting how efficiently it handles multimedia tasks. For users who spend long hours watching YouTube, Netflix, or short-form content, this efficiency becomes a major advantage.Navigation performance was another strong point. Even while using power-intensive applications like Google Maps, battery drain remained minimal. During one hour of active navigation with mobile data and location enabled, the phone lost only around 4 percent battery. This level of optimization makes the device highly dependable for travel and outdoor usage.

Built for Heavy Users and Long Sessions

The iQOO Z11x feels particularly suited for users who spend extended hours on their smartphones. Whether it’s gaming, video streaming, social media scrolling, or navigation, the device maintains strong endurance without overheating or excessive battery drain.For gamers, the large battery provides peace of mind during long sessions, while casual users may comfortably go through multiple days without needing a charger. This flexibility makes the device appealing to a wide range of users, especially those who prioritize endurance over ultra-thin designs.The iQOO Z11x successfully proves that battery life can still be a defining feature in the budget smartphone segment.

 Its 7,200mAh battery is not just a marketing number it genuinely delivers exceptional real world endurance backed by strong optimization.While the 44W charging speed may not be the fastest in 2026, the outstanding battery backup more than compensates for it.From benchmark performance to streaming efficiency and navigation usage, the phone consistently performs at a high level. Final Verdict:If your top priority in a smartphone is long-lasting battery life without sacrificing performance, the iQOO Z11x is easily one of the best options available under ₹20,000 in 2026. Big battery. Minimal drain. Built for endurance.
