| Xiaomi Poco X8 smartphone review – Probably the best phone deal of 2026 for battery life and display |
Let me be honest with you—I've reviewed a lot of mid-range phones over the years, and most of them leave me feeling pretty "meh." They're usually fine, but rarely exciting. So when I got my hands on the Xiaomi Poco X8, I wasn't expecting much. But after spending serious time with this device, I can tell you this: Xiaomi has done something genuinely impressive here. This phone delivers where it matters most, and it does so at a price that made me do a double-take.

The Display Steals the Show
The 6.83-inch AMOLED display on the Poco X8 is absolutely stunning for this price range. We're talking about a 120Hz refresh rate with a resolution of 2772 x 1280 pixels, and Xiaomi didn't skimp on brightness either. I measured around 1,000 nits in realistic testing, which means you can actually see what's on your screen when you're outside on a sunny day.
Here's what really got my attention—the response times. At just 0.8ms for both grey-to-grey and black-to-white transitions, this display is faster than many flagship phones I've tested. Whether you're scrolling through social media or playing games, everything feels buttery smooth.
One thing to keep in mind: there's some PWM flickering at 125Hz, which could bother people with sensitive eyes. It's not a dealbreaker, but it's worth mentioning if you're prone to headaches from screen time.
Battery Life That Will Blow Your Mind
Okay, let's talk about the real star of the show here. The Poco X8 packs an 8,340 mAh battery—that's not a typo. In my Wi-Fi browsing test, this phone lasted an incredible 29.5 hours. To put that in perspective, most phones in this price range tap out around 20 hours.
What does this mean in real life? You can forget your charger at home and still make it through a full day of heavy use without breaking a sweat. Or, if you're like me, you can go two full days of moderate use between charges. It's liberating.
The 67W fast charging is solid too. You won't get the crazy 120W speeds some flagships offer, but it's more than adequate for getting you back up and running quickly when you need it.

Design and Durability: Built Like a Tank
The Poco X8 has an industrial look that I actually quite like. The review unit I tested came in white with visible screws under a transparent plastic layer on the back—it's a distinctive aesthetic that sets it apart from the sea of generic-looking mid-range phones.
But here's the thing that really impressed me: this phone is rated IP68 AND IP69K. That means it can survive water immersion AND high-pressure water jets. TÜV SÜD certified it for two-meter water depths for up to 72 hours, and SGS tested drops onto granite from up to three meters. Xiaomi even claims the battery can handle temperatures from -40°C to +75°C.
At 223 grams, it's on the heavier side, but I'll take the extra weight if it means this level of durability. This is genuinely one of the toughest phones you can buy for under $400.

The Compromises You Need to Know About
No phone is perfect, and the Poco X8 has some clear trade-offs. Let me be upfront about them.
Performance is... Fine
The Snapdragon 6s Gen 4 processor in this phone won't win any speed contests. In everyday use, I noticed occasional stutters, especially when multitasking or running more demanding apps. Gaming is playable, but don't expect to run the latest titles at max settings.
The benchmark scores tell the story: Geekbench 6 single-core came in at 964, and multi-core at 2,748. Compare that to the average smartphone from the last two years (1,861 single-core and 5,651 multi-core), and you can see this isn't a powerhouse.
For basic tasks—calls, messaging, social media, web browsing—it's completely adequate. Just don't buy this expecting flagship-level performance.
Camera Quality Leaves Something to Be Desired
The 50MP main camera can produce decent photos in good lighting, but the moment conditions get challenging, this phone struggles. Low-light performance is genuinely poor—you'll need an external light source to get usable shots.
What bothers me more is that Xiaomi removed the ultra-wide camera that was present on the predecessor. Now there's just the main sensor and a 2MP depth sensor that can't even take photos on its own. That's a real downgrade.

Here's something that might be a dealbreaker for some of you: the Poco X8 only supports Wi-Fi 5 (802.11ac). In my testing, speeds topped out around 350 Mbit/s. The USB port is USB 2.0, which makes wired file transfers painfully slow compared to modern standards. There's also no eSIM support, which is increasingly important for international travelers.
Software and Long-Term Support
One area where Xiaomi genuinely shines is software support. The Poco X8 comes with Android 16 out of the box, and Xiaomi promises security updates until 2032—that's six full years. You'll also get five new Android versions, up to Android 21.
That's exceptional for a budget phone, and it's a genuine reason to choose this device over cheaper alternatives that abandon you after a year or two.
One downside: Xiaomi's operating system includes ads. They're not everywhere, but they pop up more often than I'd like. There are ways to disable most of them, but it's frustrating that this is still a thing in 2026.
Who Should Buy the Poco X8?
After spending significant time with this phone, here's my honest assessment:
Buy it if:
- Battery life is your top priority
- You need a phone that can survive rough conditions
- You want long-term software support without spending flagship money
- You primarily use your phone for basic tasks
Skip it if:
- You need good camera performance
- You play demanding mobile games
- You need fast Wi-Fi or USB connectivity
- You're sensitive to screen flickering
Final Verdict
The Xiaomi Poco X8 is a phone of extremes. It excels at the things that matter for most people—display quality and battery life—while falling short in areas like performance and camera quality.
At just under $340, it's genuinely one of the best deals of 2026 if you know what you're getting into. The 30-hour battery life and gorgeous AMOLED display make it a compelling choice for anyone who values endurance and visual quality over raw power.
Just don't expect it to be something it's not. This is a budget phone with flagship-level battery and display technology. Accept that, and you'll be very happy with your purchase.
