Realme P4 Power Review After 30 Days Testing: The Best Battery Phone in 2026?

The Realme P4 Power underwent extensive testing, and a clear assessment has emerged regarding its strengths and limitations.

Display

The device features a quad-curved display, continuing Realme’s familiar design approach. The screen is close to 6.8 inches with a 1.5K resolution and 453 PPI, delivering sharp visuals. A 144Hz refresh rate ensures smooth scrolling, though system animations can occasionally make transitions feel slightly slow.

Protection includes Gorilla Glass 7i along with a pre-applied screen guard. With a peak brightness of 6500 nits and 1800 nits in high-brightness mode, outdoor visibility remains strong. Viewing angles are solid, and multiple color tuning options are available.

However, while watching 4K videos, slight lag appears when switching between landscape and portrait modes. Minor stuttering is also noticeable during zoom operations. HDR support is available across supported platforms.

Software

The phone runs Realme UI 7 based on Android 16. The brand promises three years of OS updates and four years of security patches. Several pre-installed apps and promotional notifications are present and require manual disabling.

Some advanced multitasking features seen in higher-end models are absent due to chipset limitations.

Battery and Charging

The standout feature is the massive 10,100mAh battery. An 80W charger is included in the box.

• 50% charge: approximately 47 minutes
• Full charge: around 1 hour 45 minutes

In testing, the device delivered up to 18 hours of screen-on time, which is exceptional for this segment. Standby battery drain was minimal. Under typical usage, two to three days of battery life is achievable.

Although 27W reverse wired charging is claimed, actual output measured around 7W during testing, which falls short of the stated specification.

Camera

The phone includes a 50MP primary sensor with OIS and an ultra-wide lens.

• Rear video: 4K at 30fps
• Front camera: 16MP, Full HD at 30fps

Portrait shots show decent edge detection, but noticeable color shifts occur between 1X and 2X zoom. Digital zoom extends up to 20X, though quality is limited at higher levels.

Night photography produces slightly warm tones with minor ghosting. Video recording reveals mild flicker and occasional saturation shifts. Autofocus performance is stable, and slow-motion recording remains satisfactory.

Performance

Powered by the MediaTek Dimensity 7400 Ultra chipset with LPDDR4X RAM and UFS 3.1 storage, the device achieves benchmark scores close to 1 million (AnTuTu v11). Thermal performance remains controlled, with temperatures peaking around 42–43°C under load.

Games such as BGMI and Call of Duty support up to 90fps, though this is not a dedicated gaming phone. Heavy titles run at moderate frame rates. Everyday tasks are handled smoothly, though occasional app reloads occur.

Design and Build

Despite housing a large battery, the phone weighs 224 grams and measures 9.2mm in thickness, maintaining reasonable ergonomics. It uses a polycarbonate back and frame.

• Single speaker (around 84dB)
• Optical in-display fingerprint sensor
• Dual SIM support (no eSIM)
• USB 2.0 port (slower file transfers)
• IP66/68/69 rating
• IR blaster
• Wi-Fi 5 and Bluetooth 5.4 (no NFC)

Network stability and call quality remain consistent.

Overall Assessment

Starting at approximately ₹25,000 (8GB + 128GB variant), this device faces strong competition in camera-focused and gaming-centric categories.

The Realme P4 Power is clearly built for users who prioritize battery endurance above all else. For extended heavy usage and multi-day backup, it performs impressively.

In conclusion, the Realme P4 Power positions itself as a battery-centric smartphone, delivering standout endurance while offering balanced overall performance in other areas.
