The POCO X8 is built around one unusually clear promise: stop worrying about battery life. With an 8,340mAh silicon-carbon battery, 67W charging and 22.5W wired reverse charging, this is not a phone trying to be the lightest or the most camera-focused model in its class. It is trying to last.
Disclosure: This early assessment is based on POCO’s official Malaysia press release and specification sheet. I have not independently tested the battery life, performance, camera or durability, so manufacturer claims are identified as such.
Key takeaways
- The 8,340mAh battery is the POCO X8’s strongest reason to exist.
- A 6.83-inch 1.5K AMOLED display, 120Hz refresh rate and extensive water-resistance ratings support the endurance-focused design.
- The Snapdragon 6s Gen 4 should suit everyday use, but gaming performance and sustained heat still need hands-on testing.
- The 223g weight, modest secondary camera and older Wi-Fi 5 and Bluetooth 5.1 standards are important trade-offs.
- Malaysia pricing was announced at RM1,499 for 8GB+256GB and RM1,699 for 12GB+256GB, with lower launch promotional prices.
The battery is the real headline
The most meaningful specification here is not an AI feature or a camera mode. It is the 8,340mAh battery. POCO says this is 63.2% more capacity than the previous-generation model and can deliver more than two days of use under its internal mixed-usage test.
That claim needs independent verification because real battery life changes with signal strength, screen brightness, gaming, camera use and software settings. Even so, the capacity alone gives the POCO X8 a substantial buffer over a typical smartphone. For travellers, delivery riders, event crews, mobile gamers and anyone who spends long days away from a socket, that extra reserve is easy to understand.
POCO also says the battery should retain at least 80% of its original capacity after 1,600 complete charge cycles. The company equates that to roughly six years of regular use, based on one full cycle every 1.79 days. That is a laboratory projection rather than a guarantee, but long-term battery health is the right problem to address on a device marketed around endurance.
Charging is rated at up to 67W through a compatible PPS adapter. POCO advises buyers to check whether the power adapter is included locally. The phone also supports up to 22.5W wired reverse charging, allowing its large battery to top up another phone, earbuds or a small accessory.
A large display with a weight trade-off
The POCO X8 uses a 6.83-inch AMOLED panel with a 2772 × 1280 resolution and an adaptive refresh rate of up to 120Hz. The specification sheet lists 12-bit colour, DCI-P3 coverage, DC dimming, 3840Hz PWM dimming and three TÜV Rheinland eye-care certifications.
POCO advertises peak brightness of up to 3,500 nits, but that figure applies to 25% of the screen under specific conditions. It should not be read as sustained full-screen brightness. Outdoor legibility still needs to be judged in direct Malaysian sunlight.
The large battery and display come with a physical cost. At 223g and 8.6mm thick, this is unlikely to disappear in a pocket. Buyers who prioritise a light one-handed phone may find the endurance advantage less compelling than users who value maximum runtime.
Durability sounds impressive, but read the limits
POCO lists IP66, IP68, IP69 and IP69K resistance alongside Corning Gorilla Glass Victus 2. The company also cites SGS-certified drop resistance from up to three metres onto a smooth granite surface under controlled testing.
Those numbers are reassuring, but they are not permission to treat the phone as indestructible. Water resistance can deteriorate through wear, impacts or repair, and POCO states that liquid damage outside the certified conditions is not covered by warranty.
The new Underwater Mode is limited to static freshwater at a maximum depth of two metres for up to 30 minutes. POCO specifically says it is not intended for seawater, swimming pools, hot water or professional diving, and recommends a waterproof case. That makes the feature better understood as a controlled camera mode than a reason to deliberately submerge the phone.
Everyday performance, not flagship expectations
The Snapdragon 6s Gen 4 is manufactured on a 4nm process and uses an octa-core CPU running at up to 2.4GHz with Adreno graphics. Malaysia receives 8GB+256GB and 12GB+256GB variants; the official specification sheet pairs those configurations with LPDDR4X memory and UFS 3.1 storage.
This combination should be capable of smooth everyday work, social media, video and casual gaming, but the specification alone cannot establish frame-rate stability, thermal behaviour or long-session performance. Those results need real testing. Buyers looking primarily for maximum competitive-gaming performance should wait for benchmarks rather than treating the large battery as proof of a flagship-class gaming experience.
The phone runs Xiaomi HyperOS 3 and includes Google Gemini, Xiaomi HyperIsland and Xiaomi Offline Communication. The offline calling feature requires a SIM card and a signed-in Xiaomi account, works only with compatible devices, and is not intended for emergency communication. Connectivity otherwise includes dual-SIM support, NFC depending on market, Wi-Fi 5 and Bluetooth 5.1.
The camera system is functional rather than ambitious
The rear system combines a 50MP f/1.8 main camera with optical image stabilisation and a 2MP depth sensor. A 16MP camera handles selfies, while Dual video can record the front and rear views together.
OIS is welcome at this price because it can help with low-light stability and video. However, the official specification sheet does not list an ultrawide or telephoto camera. That limits framing flexibility compared with phones that offer a useful secondary lens. POCO’s AI tools Glare Removal, Erase Pro, Image Expansion, Image Enhancement and Beautify may simplify edits, but availability can vary by region and software version.
Image quality is one of the areas where no responsible verdict is possible from a press release. Dynamic range, skin tones, shutter consistency and night performance all need sample photos before the camera can be properly judged.
Malaysia pricing and value
POCO announced the X8 in White, Black and Orange. The September launch materials listed the following Malaysia prices:
| Variant | Normal price | Launch promotional price |
|---|---|---|
| 8GB+256GB | RM1,499 | RM1,299 |
| 12GB+256GB | RM1,699 | RM1,499 |
The promotional prices were announced for availability from 9 September through mi.com and official POCO stores on Shopee, Lazada and TikTok Shop. Because promotions change, buyers should verify the current checkout price and bundle before purchasing.
Early verdict: a clear battery-first proposition
On paper, the POCO X8’s real USP is not its list of AI features. It is the combination of an 8,340mAh battery, useful reverse charging and unusually extensive ingress protection.
The POCO X8 looks most convincing for people who value long runtime, a large screen and practical durability above a lightweight body or a versatile camera system. At the announced RM1,299 promotional price, the 8GB+256GB model presents a straightforward endurance argument. At the normal price, its value will depend more heavily on real battery results, display behaviour, camera output and sustained performance.
For now, the specifications make the POCO X8 interesting rather than proven. A full review should test how much of that large battery advantage survives demanding daily use and whether the extra weight feels worthwhile after several days in hand.
