Poco X7 Pro vs Poco M8x 5G: Key Differences

The Poco X7 Pro and Poco M8x 5G are two very different phones that share a brand name but target separate buyers. The X7 Pro is a performance-focused mid-ranger with a flagship-grade chipset and fast charging, while the M8x 5G is an entry-level 5G device built for basic tasks and long battery life. Here is a direct comparison of their specs, performance, cameras, and value to help you decide which one fits your needs.

Background: Where Each Phone Fits

Poco, a sub-brand of Xiaomi, has historically split its lineup into two clear categories. The X-series (like the X7 Pro) is aimed at gamers and power users who want near-flagship performance without paying flagship prices. The M-series (like the M8x 5G) is designed for first-time smartphone buyers, budget-conscious users, or those who need a reliable secondary device.

The X7 Pro launched as a successor to the Poco X6 Pro, continuing the trend of putting a high-end MediaTek Dimensity chip in a plastic body with a large battery. The M8x 5G, on the other hand, sits at the bottom of Poco’s 5G lineup, often competing with devices like the Redmi 13C 5G or Samsung Galaxy A15 5G. Understanding this positioning is key because it explains why the price gap is so wide and why the specs differ so dramatically.

Display and Build Quality

The most immediate difference you will notice is the screen. The Poco X7 Pro features a 6.67-inch AMOLED panel with a 120Hz refresh rate and a resolution of 2712 x 1220 pixels (roughly 446 ppi). This is a bright, vibrant display with deep blacks, ideal for watching HDR content or gaming. It also supports Dolby Vision and HDR10+.

The Poco M8x 5G, in contrast, uses a 6.74-inch IPS LCD with a 90Hz refresh rate and a resolution of 1600 x 720 pixels (about 260 ppi). While this is acceptable for basic use, colors are less saturated, viewing angles are narrower, and outdoor visibility is weaker. The lower resolution also means text and icons look slightly less sharp.

Build materials differ too. The X7 Pro uses a glass front (Gorilla Glass Victus 2) and a plastic frame with a textured back, while the M8x 5G uses a plastic body with a glass-like finish. Neither has an official IP rating, but the X7 Pro is better sealed against dust and splashes.

Performance and Software

Here is where the gap becomes a canyon. The Poco X7 Pro is powered by the MediaTek Dimensity 8400 Ultra chipset, built on a 4nm process. It delivers performance comparable to last year’s flagship phones, scoring around 1.4 million on AnTuTu (v10). The M8x 5G uses the MediaTek Dimensity 6100+ (or a similar entry-level chip), which scores around 300,000. Real-world difference: the X7 Pro can run demanding games like Genshin Impact at high settings, while the M8x 5G handles casual games and social media smoothly but will stutter on heavy 3D titles.

Both run Xiaomi’s HyperOS (based on Android 14), but the experience differs. The X7 Pro gets faster updates and more RAM options (up to 12GB LPDDR5X), while the M8x 5G typically comes with 4GB or 6GB of slower LPDDR4X. The M8x also has more pre-installed apps (bloatware), which can be annoying but is removable.

Camera Systems

The camera hardware reflects the price difference. The X7 Pro has a dual rear camera: a 50MP Sony IMX882 primary sensor (with OIS) and an 8MP ultrawide. The M8x 5G also has a 50MP main sensor (likely a Samsung ISOCELL JN1) but no OIS and no ultrawide—just a 2MP depth sensor. In practice, the X7 Pro produces sharper, more detailed photos in good light and significantly better low-light shots thanks to OIS and a larger sensor. The ultrawide on the X7 Pro is a bonus for landscape shots, while the M8x’s depth sensor is mostly useless for anything but portrait mode.

Video recording also differs: the X7 Pro can shoot 4K at 60fps, while the M8x tops out at 1080p/30fps. Front cameras are similar (16MP vs 8MP), but the X7 Pro’s selfie camera has a wider field of view.

Battery and Charging

Both phones have large batteries, but the charging speeds are worlds apart. The X7 Pro packs a 5000mAh battery with 90W wired charging (charges from 0 to 100% in about 35 minutes). The M8x 5G has a 5000mAh battery but only supports 18W charging (takes over 2 hours). Neither supports wireless charging.

In daily use, the M8x might actually last longer on a single charge because its chipset is less power-hungry and the screen is lower resolution. But the X7 Pro’s faster charging means you can top up in minutes, which is more convenient for heavy users.

Price and Value

As of early 2025, the Poco X7 Pro typically costs around $300–$350 (or ₹25,000–₹30,000 in India), while the M8x 5G is priced at roughly $150–$180 (₹12,000–₹15,000). The M8x is clearly the budget choice, but the X7 Pro offers far better performance, display, cameras, and charging for only about double the price. If you can stretch your budget, the X7 Pro is the better long-term investment because it will remain smooth for 3–4 years, whereas the M8x may feel sluggish after two years.

How to Choose

Ask yourself these questions:

• Do I play games or edit videos? If yes, get the X7 Pro.
• Do I care about screen quality for Netflix or YouTube? If yes, get the X7 Pro.
• Do I need a simple phone for calls, WhatsApp, and light browsing? The M8x is sufficient.
• Do I want to keep the phone for more than 2 years? The X7 Pro is safer.
• Is battery life more important than charging speed? The M8x wins on endurance.

If you are on a strict budget, the M8x 5G is a decent entry-level 5G phone, but it lacks the polish and longevity of the X7 Pro. If you can save up a bit more, the X7 Pro is one of the best value phones in its class.

Common Problems and Misconceptions

A common misconception is that both phones run the same software, so they will perform similarly. That is false—the chipset difference is massive. Another issue: the M8x 5G’s LCD screen is prone to ghosting (image retention) if you leave a static image on for long periods. The X7 Pro’s AMOLED does not have that issue. Also, neither phone has a headphone jack, but the X7 Pro has stereo speakers, while the M8x has a single mono speaker.

Battery degradation is another point: the X7 Pro’s 90W charging generates more heat, which can degrade the battery faster over time. Xiaomi includes a bypass charging feature (when gaming) to mitigate this, but it is still worth noting. The M8x’s slower charging is gentler on the battery.

Frequently Asked Questions

Is the Poco X7 Pro worth the extra money over the M8x 5G?

Yes, for most users. The X7 Pro offers a significantly better screen, faster performance, better cameras, and much faster charging. The M8x is only worth it if your budget is absolutely tight and you only need basic functions.

Which phone has a better battery life?

The M8x 5G typically lasts longer on a single charge because its chipset is less power-hungry and the screen is lower resolution. However, the X7 Pro charges much faster, so you can top up quickly.

Can the Poco M8x 5G play PUBG Mobile?

Yes, but at low graphics settings and around 40–50 fps. The X7 Pro can run PUBG at smooth + extreme settings with 60 fps.

Do both phones support 5G?

Yes, both support 5G, but the X7 Pro supports more bands (including n28 and n77) which is better for international roaming. The M8x covers the common bands in most regions.

Which phone gets more software updates?

The X7 Pro is guaranteed to receive 3 years of Android updates and 4 years of security patches. The M8x typically gets 2 years of OS updates and 3 years of security patches.

Is the M8x 5G good for seniors or kids?

Yes, the M8x is a good choice for seniors or kids because it is simple, has a large screen, and its lower performance is not a drawback for basic tasks. The X7 Pro might be overkill and more expensive.
