Battery capacity has quietly become one of the most competitive areas in the smartphone market, and Realme is leaning into it harder than most. The newly detailed P4 Power 5G focuses squarely on endurance, pairing a 10,001mAh battery with mid-range hardware designed to keep performance steady rather than chase benchmark records. When you consider that Samsung is rumored to be sticking with a 5,000mAh battery for the Galaxy S26 Ultra it's easy to wonder why the Korean brand is short-changing its customers.
What makes it notable isn’t just the number; Realme has managed to fit that capacity into a 9.08mm body weighing about 219g. This puts it much closer to a normal handset than typical “battery phones” and is just a single gram heavier than Samsung's Galaxy S25 Ultra, which has only a 5,000mAh battery.
Display & design
The P4 Power 5G features a 6.8-inch FHD+ panel with an adaptive refresh rate up to 144Hz and a peak brightness of 6,500 nits. In practical terms, that combination suggests a device aimed at everyday smoothness rather than pure resolution — fast scrolling, readable outdoors, and efficient power usage.
Realme also leans into a semi-transparent industrial look with exposed internal-style detailing, alongside IP66/IP68/IP69 protection ratings and reinforced glass. That durability focus aligns with the battery theme: this is meant to be a long-haul daily device rather than a fragile showcase phone.
Performance & software
Powering the device is MediaTek’s Dimensity 7400 Ultra paired with a Mali-G615 GPU. It’s a pragmatic choice — not flagship-tier, but modern enough for multitasking and sustained use without excessive heat.
The phone runs realme UI 7.0 based on Android 16 and includes system-level animation optimisation and frame scheduling designed to keep interactions smooth over time.
Battery & charging
The headline feature is the 10,001mAh battery, supported by 80W wired charging and 27W reverse charging. Realme positions it as a multi-day device rather than a single-day fast-charging phone, emphasizing fewer charge cycles rather than faster ones.
Bypass charging is also included, allowing power to run directly to the system during heavy use like gaming or navigation, which should reduce heat and long-term battery wear.
Cameras
The camera setup is straightforward:
- 50MP main camera with OIS
- 8MP ultra-wide
- 16MP selfie camera
Video recording reaches 4K at 30fps, clearly positioning imaging as functional rather than flagship-level.
Connectivity & extras
The phone supports a wide range of global 5G bands, Bluetooth 5.4, and dual-band Wi-Fi. Realme also includes loud “UltraBoom” speakers and large-area cooling hardware aimed at stable performance during long sessions.
Takeaway
The Realme P4 Power 5G isn’t trying to compete on camera prestige or top-tier performance. Instead, it targets a specific frustration — battery anxiety — and builds the rest of the phone around that goal.
For users who prioritise reliability over peak specs, it’s shaping up to be a practical alternative to typical mid-range phones that still require nightly charging.
