Is the Infinix Zero X Worth Buying in 2025? Practical Buyer’s Guide & Real-World Review
The Verdict: Do not buy the Infinix Zero X in 2026 as a primary device. While refurbished listings tempt buyers with a 5x optical periscope zoom at rock-bottom prices, the hardware has fundamentally degraded. It is permanently stuck on an insecure, outdated version of Android. Unless you are a camera enthusiast buying a cheap secondary toy, your money is better spent on a modern 5G entry-level phone.
It is easy to look at a spec sheet from 2021 and assume it translates perfectly to today. The Infinix Zero X looks incredible on paper. A 120Hz AMOLED display. A 5x periscope zoom lens. A capable MediaTek Helio G95 processor.
But smartphones do not age on paper. They age in the real world.
After putting a refurbished Zero X through its paces in the unforgiving July heat of Navi Mumbai, the reality is stark. Standard reviews blame the phone’s sluggishness on its older processor and its camera issues on software bugs. They are wrong. What is actually killing this phone in 2026 isn't software it is hardware physics.
Here is what is really happening inside the Infinix Zero X, and why you should steer clear.
When you open an app on a four-year-old phone and wait seven seconds for it to load, the instinct is to blame the aging chipset. The Helio G95 isn't cutting-edge, but it is not the culprit here.
The real bottleneck is the UFS 2.2 storage.
Smartphones use NAND flash memory to store your apps and operating system. Every time you download a file, clear a cache, or install an update, you consume a read/write cycle. After years of daily use, the memory cells physically degrade. This phenomenon, known as NAND degradation, means the storage drive simply cannot retrieve data fast enough to feed the processor. The phone feels heavy and sluggish not because the G95 is too weak, but because it is constantly waiting on a dying hard drive.
Most phones throttle smoothly when they overheat. The Zero X stutters violently. Why?
Because of its architecture. To drive a 120Hz display with a mid-range processor, Infinix utilized a "Dual-Chip" design, pairing the Helio G95 with a dedicated secondary display chip. When the chassis overheats, the primary G95 processor aggressively throttles its clock speed down to prevent melting. However, the secondary display chip keeps desperately trying to push 120 frames per second.
This creates a processor-to-display desync. The brain is running at half speed while the screen demands full speed, resulting in jarring input lag and micro-stutters that ruin the user experience.
Combine four years of physical micro-impacts dropping the phone on a desk, daily walking with the extreme internal heat of the device melting the micro-adhesives holding it together. The result? The prism physically sags out of alignment. This "periscope drift" is permanent. You cannot fix hardware degradation with a software patch.
The Infinix Zero X was an ambitious piece of engineering in its time. Today, it is a fascinating case study in how mobile hardware degrades. The lack of security updates makes it unsafe for banking, and the physical degradation of its storage and optics makes it frustrating to use. Let this one stay in the history books.

The Lag Isn't the Processor It's Dead Storage

The Dual-Chip Thermal Desync
Heat is the enemy of performance, especially during an Indian summer. Push the Zero X with a heavy gaming session, and the temperature near the camera module quickly spikes to 50°C.Most phones throttle smoothly when they overheat. The Zero X stutters violently. Why?
Because of its architecture. To drive a 120Hz display with a mid-range processor, Infinix utilized a "Dual-Chip" design, pairing the Helio G95 with a dedicated secondary display chip.

This creates a processor-to-display desync. The brain is running at half speed while the screen demands full speed, resulting in jarring input lag and micro-stutters that ruin the user experience.
The Physics of "Periscope Drift"
The defining feature of the Zero X is its 5x optical periscope zoom. Many long-term users complain that the zoom camera has lost its sharpness or struggles to focus, assuming it is a software glitch. It is not. It is mechanical failure.A periscope camera doesn't look straight out the back of the phone. It uses a delicate internal glass prism to bounce light 90 degrees down the length of the chassis. This heavy prism is suspended on tiny electromagnetic coils to provide Optical Image Stabilization (OIS).
Combine four years of physical micro-impacts dropping the phone on a desk, daily walking with the extreme internal heat of the device melting the micro-adhesives holding it together. The result? The prism physically sags out of alignment. This "periscope drift" is permanent. You cannot fix hardware degradation with a software patch.
Final Takeaway
The Infinix Zero X was an ambitious piece of engineering in its time. Today, it is a fascinating case study in how mobile hardware degrades. The lack of security updates makes it unsafe for banking, and the physical degradation of its storage and optics makes it frustrating to use. Let this one stay in the history books.
