Overview
Realme has taken a bold step with the P4 Power, the company’s first device to feature a 10,001 mAh Silicon‑Carbon (Si‑C) battery. Launched less than a year after a prototype demo, the phone targets users who need marathon‑level endurance without sacrificing modern smartphone features.
Battery & Longevity
The Si‑C battery is rated for 1,650 charge cycles and is engineered to retain at least 80% of its original capacity after eight years of use. Realme claims an average user will experience 392 fewer charge cycles over four years compared with a typical phone, and the battery can endure 150‑200 more cycles than conventional lithium‑ion cells.
- 10,001 mAh capacity (10,000 mAh class)
- 80% capacity retention after 8 years
- 1,650 charge‑cycle rating
- Estimated 392 fewer cycles over 4 years
Endurance in Real‑World Use
On a full charge the P4 Power can:
- Play BGMI for ~12 hours
- Stream YouTube for >32 hours
- Run navigation for >21 hours
- Record 4K video for 12 hours
- Make voice calls for ~4 hours at 5% battery remaining
Charging Performance
The device supports 80W fast charging via Realme’s SuperVOOC charger, reaching 50% in about 36 minutes. USB‑PD PPS chargers are limited to 55W. Reverse charging is also available at 27W, enough to top‑up an iPhone 16 Pro (3,582 mAh) to 50% in 27 minutes.
- 80W wired fast charge (SuperVOOC)
- 50% charge in ~36 minutes
- 27W reverse charge (phone‑as‑power‑bank)
Durability & Build
Despite the massive battery, the phone is only 9.08 mm thick and weighs 219 g. It meets IP66, IP68 and IP69 standards, surviving 2 m of water, temperatures from –30 °C to 56 °C, flat‑compression, and a 1 m drop test.
- IP66/IP68/IP69 water and dust resistance
- Operational temperature: –30 °C – 56 °C
- Drop‑tested from 1 m
- 9.08 mm thickness, 219 g weight
Display & Camera
A 6.8‑inch quad‑curved panel delivers a 144 Hz refresh rate, 1,280 × 2,800 px resolution and up to 6,500 nits peak brightness. The camera setup includes a 50 MP Sony IMX882 main sensor with OIS, an 8 MP ultra‑wide lens (112°) and a 16 MP selfie camera.

- Android 16 / Realme UI 7.0
- 3 years OS updates + 1 year security patches
Verdict
The Realme P4 Power sets a new benchmark for battery capacity and longevity in mainstream smartphones. While its chipset may not stay flagship‑grade for eight years, the combination of a 10,001 mAh Si‑C battery, robust charging options, and rugged IP‑ratings makes it an attractive choice for power users, travelers, and anyone who values endurance over raw performance.
