The POCO X8 Power 5G is the battery-capacity pick on paper, with third-party listings describing a 10,000mAh battery and 100W charging. The realme P3 Ultra has manufacturer-listed Dimensity 8350 Ultra hardware, a 120Hz quad-curved display, and a 6000mAh battery with 80W charging. Neither specification sheet establishes real-world endurance or overall performance, so the better choice depends on which features matter most—and on the exact India-market variant price you can verify.
How the two phones compare
The specifications below come from different kinds of sources: realme’s official product page for the P3 Ultra, and reporting or a third-party listing for the POCO X8 Power 5G. The POCO details should be treated as attributed listing information, not as manufacturer-confirmed specifications.

Battery and charging: POCO leads on listed capacity
The POCO X8 Power 5G’s reported 10,000mAh capacity is substantially larger than the P3 Ultra’s manufacturer-stated 6000mAh. Its reported 100W charging is also higher than the realme’s 80W figure. That makes the POCO the more compelling specification-sheet option if battery size and charging rating are priorities.

Performance: the chipset names are not a head-to-head result
realme identifies the P3 Ultra’s chipset as the MediaTek Dimensity 8350 Ultra. The Snapdragon 6 Gen 5 attribution for the POCO comes from a third-party listing. Without controlled benchmark or gaming tests for these exact phones, the chipset names alone do not prove which device is faster, runs cooler, or sustains performance better.
If gaming or demanding apps are central to your decision, look for independent tests of both retail models under comparable conditions rather than choosing from processor branding alone.

Display and cameras: choose by design preference, not headline numbers
The P3 Ultra’s 120Hz quad-curved display is the clearer fit if you prefer a curved-screen design. The POCO listing describes a larger, 6.83-inch 120Hz AMOLED panel; check the exact product listing and retailer details for the device you plan to buy. Screen shape and size are useful distinctions, but the available specifications do not establish which screen is brighter or better calibrated.
For rear cameras, realme specifies a Sony 50MP OIS camera, while 91mobiles lists a 50MP plus 8MP camera setup for the POCO. These specifications do not establish photo or video quality, and no independent camera comparison is available here. Do not treat megapixel totals or camera count as a substitute for sample images and testing.

India prices: compare the same configuration and checkout terms
As listed by 91mobiles on October 6, 2026, the POCO X8 Power 5G costs ₹35,999 for 8GB/128GB and ₹38,999 for 8GB/256GB. The P3 Ultra prices surfaced on comparison pages are not a like-for-like pair: the pages include a ₹31,999 base listing and a ₹33,499 12GB/256GB listing. A fixed rupee price gap would therefore be misleading.
Before deciding, compare the same RAM and storage tier where available, then check the seller’s current checkout total, stock, discounts, and offer conditions. Listing prices can change and may not match the amount payable at checkout.
Which one should you choose?
- Consider the POCO X8 Power 5G if the listed 10,000mAh battery and 100W charging are your leading priorities, and its exact variant is available at a price you consider worthwhile.
- Consider the realme P3 Ultra if you want the manufacturer-specified Dimensity 8350 Ultra platform or prefer a 120Hz quad-curved display, and its verified price and configuration suit you.
- For gaming or camera quality, wait for independent tests of the exact phones; the cited specifications do not settle those comparisons.
- For value, compare matching RAM/storage configurations and live seller totals rather than subtracting prices from unlike listings.
Do not confuse POCO X8 Power 5G with POCO X8
The POCO X8 and POCO X8 Power 5G are separate models. POCO’s official X8 page lists 8340mAh and 67W, figures that do not verify the Power 5G’s reported 10,000mAh battery and 100W charging. POCO X8 official product page. Check the full model name when reading specifications or shopping; similarly named listings are not interchangeable.
