Poco X8 and X8 Power Reveal 9,000–10,000mAh Batteries, Specs

Battery arms race, round two. Poco just turned up the voltage on how long a phone can actually last off the charger.

POCO India has pinned the date: September 4 at 12 PM, when the Poco X8 and a hulking X8 Power will make their official debut in India. The teasers were blunt — not vague hints — and the company already spilled most of the hardware headlines for both phones.

The standard X8 looks built for endurance without sacrificing modern polish. It carries a 9,000mAh cell and supports 67W wired charging plus 22.5W reverse wired charging for topping up accessories. The display is a 6.83-inch AMOLED panel with a so-called “1.5K” resolution, a 120Hz refresh rate and a peak brightness that Poco claims reaches 3,500 nits. Gorilla Glass Victus 2 protects the glass. Audio? Dual stereo speakers. Durability? An unusual stack of IP ratings—IP66, IP68, IP69 and IP69K—suggesting Poco wants to brag about resilience as much as battery life.

POCO X8 Power packs a staggering 10,000mAh battery with 100W wired charging. The company’s marketing even teases multi-day runtime estimates—numbers that, if true under real-world use, would shift expectations for mid-range and budget phones alike.

Hardware watchers have already connected the dots. The X8 could effectively be a rebadged Redmi Note 17 Pro, while the X8 Power may map to the Redmi Note 17 Pro Max. That theory lines up with the leaks we’ve seen, but official pricing is still pending; rumors have floated ranges that give a hint of where Poco might position each device, though nothing is confirmed.

For a quick technical snapshot, here are the key specs Poco has revealed so far:

• Poco X8: 9,000mAh battery, 67W wired charging, 22.5W reverse wired charging; 6.83" AMOLED, 1.5K, 120Hz, 3,500 nits; Gorilla Glass Victus 2; dual stereo speakers; IP66/IP68/IP69/IP69K.
• Poco X8 Power: 10,000mAh battery, 100W wired charging; multi-day battery claims; other details appear to mirror the higher-end Redmi hardware.

Big batteries are headline-grabbing. But headline alone doesn’t make a great phone: charging speed, thermal management, software optimization and camera performance will determine whether these X8 models are mere endurance showcases or genuinely balanced devices. Either way, if you care more about running your day (or several days) without hunting for a charger, September 4 suddenly feels like an important date.
