The POCO X8 Pro Max has arrived, planting its flag firmly in the sub-flagship territory under Xiaomi‘s value-focused banner. As the very first “Pro Max” model in the POCO line, the naming convention alone means it has big shoes to fill.

So, does this oversized, overpowered everyday driver actually deliver on its bold moniker? If you want the short answer: Yes, mostly. For the long answer, read on for our full review.

Huge battery in a manageable footprint

Right out of the box, the POCO X8 Pro Max delivers a flagship-tier aesthetic that feels premium in the hand. It sports a cold metal build with flat edges and rounded corners, highly reminiscent of the POCO F8 Ultra we reviewed last November.

The company sent us the Black variant, which also comes in Blue and White, featuring a smooth matte finish that does an admirable job of repelling fingerprints and keeping the smartphone looking pristine. And although the overall aesthetic is admittedly familiar and a bit unexciting, POCO included a subtle red accent around the power button. It’s a nice touch that gives the dark chassis some much-needed flair.

What’s mind-boggling here are the dimensions. The body is a mere 8.2mm thick and weighs just 218 grams. That might sound standard, until you realize it’s packing a giant 8,500mAh battery. To put that into perspective, it shares the footprint of the F8 Ultra while housing a significantly larger power cell. Taking it a step further, the POCO X8 Pro Max is actually slimmer and lighter than the Apple iPhone 17 Pro Max despite having a vastly superior battery backup. How Xiaomi managed to squeeze this much battery capacity into a phone that doesn’t feel like an actual brick is beyond us.

Durability is another major selling point. Equipped with IP68, IP69, and IP69K ratings, this model provides top-level protection against dust and water ingress, giving you a rugged peace of mind rarely found in standard midrangers. If you regularly commute, use your handset for fieldwork, or frequently brave unpredictable Philippine weather, this is a godsend. Combined with the durable Corning Gorilla Glass 7i up front, these ratings mean you could literally hose mud or oil off this device with a pressure washer if the need ever arose.

Our POCO X8 Pro Max unboxing video features the European version. In the Philippines, the smartphone comes with a charger included in the box

On the audio front, the POCO X8 Pro Max’s symmetrical stereo speakers pump out rich, balanced sound with identical or near-equal output from both units. They support Dolby Atmos and feature a hilarious — and potentially useful — 400% loud mode for noisy environments. Predictably, there is no 3.5mm audio jack. While expected in 2026, it still would have been nice to have, considering this smartphone is positioned as the ultimate, do-everything daily driver.

Xiaomi did throw a bone to the gamers with customizable dual RGB rings surrounding the rear camera module. By default, they double as a nifty charging indicator: If they glow green, you know you’ve got enough juice to survive the day without tapping the display. You can also set them to sync and dance along to your playlists on YouTube Music, adding a fun, party-trick vibe around the back.

Flipping over to the screen, you’re greeted by a 6.83-inch 1.5K AMOLED display. It’s vibrant, punchy, and boasts a simulated 12-bit color depth capable of producing 68 billion colors. Brightness is pretty high; it peaks at 3,500 nits across 25% of the panel with a High Brightness Mode of 2,000 nits on paper. In plain English, that means you won’t have to squint or hunt for shade just to read an email or watch a video outdoors.

If there’s one minor gripe about the display, it’s the refresh-rate management. You can lock it at 60Hz to save battery, or use the Default setting, which hits 120Hz in the UI and drops to 60Hz for video streaming. Unfortunately, there is no 90Hz middle-ground, nor can you manually enforce it per app. As we saw with the exceptionally long-lasting Xiaomi 17, a more granular variable refresh rate does wonders for everyday battery consumption.

Meanwhile, the ultrasonic in-display fingerprint sensor is a significant upgrade, unlocking the phone much faster and more accurately than traditional optical sensors. Add in a tight, flagship-level haptic motor, and the POCO X8 Pro Max nails the premium user experience.

Maximum muscle meets peak endurance

Inside, the POCO X8 Pro Max is powered by the MediaTek Dimensity 9500s, built on TSMC’s advanced 3nm process, making this the first global device to use this specific platform. It features an octa-core setup spearheaded by a blistering Cortex-X925 core clocked at up to 3.73GHz, an Immortalis-G925 MC11 GPU, and MediaTek’s NPU 890.

Our review unit ships with 12GB of LPDDR5X RAM and 512GB of UFS 4.1 storage. You can opt for the cheaper 256GB model, but, as always, we strongly advise against it. With massive open-world mobile titles frequently ballooning past the 30GB mark, and local PC emulation becoming a real option for Android devices in this performance tier, that base storage will fill up much faster than you think. Cheaping out now just means you’ll be painstakingly deleting photos or uninstalling games a few months down the line.

Since we had no prior experience with the Dimensity 9500s, we were eager to push it. We’re happy to report that it didn’t disappoint. The POCO X8 Pro Max notched nearly 2.8 million points in the latest Antutu Benchmark, slotting comfortably between the older Dimensity 9400 (2.6 million points) and the current-gen flagship Dimensity 9500 (3.4 million points).

In practice, this model is lightning-quick. It chewed through our gaming tests effortlessly. The thermal management is impressive, too. We played Wuthering Waves for over two straight hours on the demanding Ultra preset at 60 frames per second, and the chassis never got uncomfortably hot to handle.

Speaking of gaming, let’s talk about that 8,500mAh battery. With a capacity this massive, you expect wild numbers, and the POCO X8 Pro Max absolutely delivers. Take a look at our battery-drain test results:

• Wuthering Waves: 28% drain (2 hours, Ultra preset, 60 FPS)
• Where Winds Meet: 8% drain (1 hour, Ultra preset, 30 FPS)
• Warframe: 12% drain (1 hour, High preset, Dynamic Resolution disabled, 60 FPS)
• GRID: Legends 13% drain (1 hour Graphics preset, 30 FPS)
• Mobile Legends: 13% drain (1 hour, Ultra preset, 120 FPS)
• YouTube: 6% drain (1 hour, 1080p Premium, over Wi-Fi)
• Netflix: 8% drain (1 hour, 720p, over Wi-Fi)

In our standard PCMark battery-rundown test, the unit lasted a staggering 22 hours and 6 minutes. While it’s about an hour or two shy of the best results we’ve seen this year, it’s especially remarkable given the larger screen and lack of variable refresh rate. For most people, the POCO X8 Pro Max would be a legitimate two-day smartphone. In a market where we’ve been conditioned to accept daily charging as the norm, finding this kind of multiday endurance is like spotting a unicorn, or driving past a gas station with low prices. It just doesn’t happen anymore.

And when you eventually run that 8,500mAh tank dry, the 100-watt fast charging tops the smartphone up from empty to 100% in roughly 60 minutes. It can also moonlight as a power bank with up to 27-watt reverse charging.

In some markets, you’ll need to shell out for a separate compatible charging brick and high-speed cable. But in the Philippines, we’re told the POCO X8 Pro Max will come with a charger in the box. That’s great news. Just don’t forget to dive into the battery settings to disable “Smart charging” and select “Top speed” to enjoy that full 100-watt capability.

There is, however, one caveat for hardcore gamers. The lack of bypass charging is a glaring omission that holds the POCO X8 Pro Max back from being a true, uncompromising gaming device. Unfortunately, this continues a frustrating trend, as the feature is entirely absent across current Xiaomi and POCO models.

For the uninitiated, bypass charging allows your phone to draw power directly from the plugged-in cable, effectively bypassing the battery. This is crucial for gamers because it drastically reduces heat generation, preventing thermal throttling and frame drops during intense sessions — while also protecting the long-term health of the battery. Without it, firing up demanding titles and staying tethered to an outlet will inevitably generate excess heat, which is a shame for a unit with this much raw computing power.

Almost the perfect package

So, to recap, the POCO X8 Pro Max is a battery beast wrapped in a premium chassis, delivering stellar performance and multiday endurance. Is it the perfect package? Well, not quite.

If there’s a compromise to be found here, it’s the camera system. It isn’t bad, but compared to the rest of the hardware, it’s clearly where Xiaomi cut corners to keep the price tag aggressive. That said, you can squeeze more out of these cameras. We highly suggest using the native Pro mode and shooting in RAW format, to give you plenty of creative control to fine-tune the colors and exposure later in professional apps like Lightroom.

The main shooter is a 50-megapixel Light Fusion 600 sensor with optical image stabilization or OIS and a bright f/1.5 aperture. This isn’t a brand-new sensor, by the way. The Light Fusion 600 has been around the block for some time now, and it’s clear that Xiaomi’s engineers have figured out how to squeeze every bit of potential out of it. The end result is a mature, refined camera experience you can rely on for your daily snaps.

Sample shots

Surprisingly, the 8-megapixel ultra-wide doesn’t feel like a letdown. It’s actually quite capable, delivering usable shots that look good on a social feed. You’ll notice a dip in sharpness compared to the primary sensor if you go pixel-peeping, but for general landscape work, it performs better than its modest resolution suggests.

There’s zero telephoto hardware to be found here. The native camera app technically allows you to push the digital zoom to 10x, yet anything past 5x turns the image into a watercolor painting. Even at that 5x mark, you need plenty of daylight to get a truly usable crop.

The 20-megapixel front-facer, on the other hand, gets the job done for selfies and video calls, but it won’t blow you away. The lens itself is wide, and if you’re looking to do some quick vlogging, you can shoot 1080p video at a smooth 60 frames per second.

Final thoughts

POCO boldly advertises the POCO X8 Pro Max as the ultimate workhorse — and for the most part, the reality lives up to the marketing hype. It succeeds in almost every conceivable metric, nailing both raw performance and multiday endurance to exceedingly rare levels. Finding this specific combination in this price segment isn’t just unusual; it’s something we’ve never encountered before, and it’s an achievement that deserves to be celebrated.

By pairing that gigantic battery with the highly capable MediaTek Dimensity 9500s chip and great hardware, POCO has crafted the most practical phone of the year. If you can forgive the uneven camera experience and the absence of bypass charging, this device isn’t just a sub-flagship triumph; it’s a masterclass in utility.

In the Philippines, the POCO X8 Pro Max officially starts at ₱25,999 (around $434) for the 12GB/256GB variant, while the 12GB/512GB kit retails for ₱27,999 ($467). On their own, those are already competitive prices for this level of hardware.

However, during the initial early-bird sale period, you can purchase the base model for as low as ₱18,999 ($317). Let that simmer for a moment. To get a 3nm Dimensity 9500s processor, a record-breaking 8,500mAh battery, and a quality AMOLED display at that sum is, quite frankly, insane.
