Realme has unveiled its first smartphone with a truly massive battery, the P4 Power, featuring a 10,001mAh cell. The device promises outstanding endurance, coming less than a year after Realme showed a 10,000mAh prototype.
The P4 Power uses a next-generation silicon-carbon battery designed for long-term performance. Realme claims it can retain at least 80% of its original capacity after eight years and is rated for 1,650 charge cycles.
On a full charge, the P4 Power can handle nearly 12 hours of BGMI gaming or over 32 hours of YouTube playback. Navigation lasts more than 21 hours, while 4K video recording can continue for 12 hours. Even with just 5% battery remaining, the phone allows for roughly four hours of calls or over an hour of GPS navigation use.
This massive endurance is why Realme confidently promises eight years of effective use. The company estimates that after four years, an average user will have completed 392 fewer charge cycles compared to a typical phone. Additionally, the silicon-carbon battery supports 150-200 more cycles than standard lithium batteries.
Charging Performance
The P4 Power supports 80W fast charging. While not as extreme as Realme’s previous 240W tech, it still fills the battery to 50% in just 36 minutes. Note that 80W speeds require SuperVOOC chargers, while USB PD PPS chargers are capped at 55W.
Reverse charging is also impressive. Using the P4 Power, an iPhone 16 Pro (3,582mAh) can reach 50% charge in only 27 minutes. That effectively turns the smartphone into a powerful power bank.
Design and Durability
Despite the enormous battery, the P4 Power measures 9.08mm in thickness and weighs 219g, only 11g heavier than the 7,000mAh Realme P4x.
The phone is built to survive extreme conditions. Its battery works between -30°C and 56°C and resists flat compression. Drop-tested from one meter, it also carries IP66, IP68, and IP69 ratings. The phone can withstand exposure to water up to 2m deep and is resistant to both hot (85°C) and cold (0°C) water.
Camera
The P4 Power retains the same display as the standard P4. It has a 6.8-inch quad-curved screen with a 144Hz refresh rate, 1,280 x 2,800 resolution, and peak brightness of 6,500 nits.
The rear camera setup includes a 50MP main shooter (Sony IMX882) with f/1.8 lens and OIS, capable of recording 4K video at 30fps. It also has Night Portrait Bokeh mode. An 8MP ultra-wide camera covers 112°, while the 16MP front camera has an 85° field of view.
Performance and Colors
Powering the phone is the Dimensity 7400 Ultra chipset. It pairs with a 4,613mm² vapor chamber and a 13,743mm² graphite sheet to manage heat efficiently during gaming and heavy tasks.
The P4 Power comes in Flash Orange and Power Silver. The back panel is split: the lower matte section houses the battery, and the top transparent section gives a peek inside, revealing elements like the NFC coil.
