This Phone Has the Best Battery Life I’ve Ever Tested

According to reviewer testing published by TechRadar, the Xiaomi Poco X8 Pro Max arrives as a mid-range Android smartphone featuring an 8,500 mAh battery, a 6.83-inch 120Hz AMOLED display, and a starting price of 5,990 kronor for the 256GB model. Released on March 17, 2026, the device prioritizes longevity and multi-day battery performance over flagship camera arrays, offering a MediaTek Dimensity 9500s chipset and 12GB of RAM.

Poco X8 Pro Max Pricing and Storage Configurations

According to launch details from TechRadar, the Poco X8 Pro Max became available on March 17, 2026, alongside the standard Poco X8 Pro. In Sweden, the base model with 12 GB of RAM and 256 GB of internal storage retails for 5,990 kronor. For an additional 500 kronor, buyers can upgrade to the 512 GB storage configuration priced at 6,490 kronor. Reviewers note that this 500-kronor gap makes the higher storage tier an attractive option for users storing large media libraries or demanding applications.

Battery Life and 100W Fast Charging Performance

According to TechRadar’s hands-on testing, the defining feature of the Poco X8 Pro Max is its massive 8,500 mAh battery, which delivers between two and three days of normal daily use on a single charge. Despite the unusually large capacity, the phone measures 8.2 mm thick and weighs 218 grams. When power finally runs low, the device supports 100W wired fast charging, which replenishes the battery from empty in roughly 45 minutes using a compatible adapter. Additionally, the phone functions as a portable power bank via 27W reverse wired charging.

Pro Tip: Because the retail box includes only a USB cable and no wall adapter, purchasers need to supply their own high-wattage charger to take advantage of the 100W fast-charging speeds.

Display Specifications and Media Capabilities

According to hardware specifications outlined by TechRadar, the Poco X8 Pro Max incorporates a 6.83-inch AMOLED panel with a resolution of 1,280 x 2,772 pixels. The display features a 120 Hz refresh rate, HDR10+ support, and a peak brightness rating of 3,500 cd/m². Reviewers highlight that the color depth minimizes color banding during video playback, while integrated stereo speakers with Dolby Atmos support enhance the overall multimedia experience.

Performance and Gaming Hardware

According to benchmark results reported by TechRadar, the Poco X8 Pro Max runs on a MediaTek Dimensity 9500s processor paired with 12 GB of RAM across all configurations. In performance evaluations, the device achieved strong results in the Geekbench 5 multi-core test and in 3DMark Wild Life Extreme. Reviewers noted that the phone handled demanding online shooters and strategy game ports at high graphics settings without significant thermal throttling.

Software Support and Interface

According to TechRadar, the smartphone ships with Android 16 and Xiaomi’s HyperOS 3 interface. Reviewers point out that the software includes a significant amount of pre-installed bloatware that requires manual removal. For ongoing maintenance, Poco promises four years of Android system updates and six years of security patches.
