realme P4 Power Review

Smartphone brands have spent years convincing us that thinner, lighter, and more premium-looking devices are what we should want. But lately, there’s been a noticeable shift happening across the industry.

Instead of trying to squeeze a little more battery life out of roughly 5,000mAh cells, manufacturers are finally embracing newer silicon-carbon battery technology to push capacities far beyond what was previously possible.

And the realme P4 Power might be one of the most interesting examples of that trend yet.

At first glance, it looks like a fairly typical midrange smartphone. But underneath all of that sits the phone’s biggest talking point, a massive 10,001mAh battery!

–That’s not a typo.

realme has somehow managed to fit a battery capacity that’s closer to a power bank than a smartphone into a device we don’t mind keeping for day-to-day use.

The question is whether the rest of the phone is good enough to make that battery worth caring about; Find out in this review.

Design and Construction

Considering the size of the battery inside, the realme P4 Power is surprisingly manageable in-hand.

The phone measures 9.08mm thick and weighs approximately 223 grams. While that definitely places it on the heavier side of modern smartphones, it never feels quite as ridiculous as the battery capacity might suggest.

In fact, the weight distribution is handled fairly well.

The device features a curved AMOLED display in front paired with a relatively modern design language that helps it avoid looking like the rugged battery-focused smartphones of old. (ehm, Energizer Powermax, ehm)

Build quality feels standard overall; polycarbonate frame and rear panel, volume rocker plus power button on the right side, dual nano SIM, primary mic for calls, Type-C port and speaker at the bottom.

And finally, a secondary mic and IR blaster on top.

realme has also included IP66, IP68, and IP69 ratings for water and dust resistance, meaning the P4 Power is certified for freshwater submersion of 1.5m for up to 30 minutes, as well as, protection from dust-sized particles, close-range high-pressure sprays, and high temps of up to 80°C.

And there’s Corning Gorilla Glass 7i protection for the display as well.

Of course, there’s no escaping physics entirely. Users who prioritize lightweight designs will immediately notice the difference, as this handset does sit in the plus-size category.

Still, for what this phone is trying to accomplish, realme has done a respectable job keeping the overall dimensions under control matched with a palatable aesthetic.

Display, Multimedia and Biometrics

The realme P4 Power features a large 6.8-inch 1.5K curved AMOLED display with support for up to a 144Hz refresh rate (2800 x 1280 resolution).

The panel itself looks good. Colors appear vibrant out of the box without looking excessively saturated, we did set the display to the Cinematic color profile for our review.

Display contrast is naturally strong thanks to the AMOLED panel, and viewing angles remain excellent throughout.

Peak brightness is also impressive on paper, reaching up to 1800 nits in High Brightness Mode. Outdoor visibility remains good even under direct sunlight, with HDR10+ support from the Widevine L1 certified panel.

The higher refresh rate also helps the interface feel noticeably smoother when scrolling through social media, browsing websites, or navigating menus.

For multimedia consumption, the AMOLED panel does much of the heavy lifting here since we only have a MONO speaker system with this device. Volume does have a 400% mode but in our opinion having a good stereo audio system can easily eclipse this aspect.

Whether you’re watching Netflix, YouTube, or even vertical videos, the display provides a vibrant and immersive experience that feels more premium than what many users might expect from a battery-focused device.

Then again, audio immersion from the mono speaker is where it falls short since we can easily cover it up with our palms, especially in horizontal viewing.

For biometrics, the phone features an in-display optical fingerprint scanner alongside face unlock support.

Fingerprint recognition feels quick and reliable enough for daily use, while face unlock remains as convenient but in our opinion, not as secure.

Cameras

The camera system on the realme P4 Power feels practical rather than ambitious. At the rear we get a 50MP main camera with OIS and an 8MP ultrawide. While in front there’s a 16MP camera for selfies.

The inclusion of optical image stabilization is arguably more important than chasing higher megapixel counts, especially within this price category.

realme P4 Power Sample Photos

Tuesday, Jun 2

In daylight conditions, the main camera captures detailed images with good dynamic range and pleasant color reproduction. realme’s image processing tends to lean slightly toward punchier colors, but results generally remain social-media friendly without appearing overly artificial.

The ultra-wide camera does its job for landscape photography and group shots, though image quality naturally takes a step down compared to the primary sensor.

Without a dedicated telephoto sensor, the high megapixel main camera surprisingly takes good shots up to 5x zoom. Anything passed that warrants a drop in image quality although still fairly usable with the help of AI post processing.

Low-light performance is respectable thanks to OIS support, helping reduce blur and improve image stability when lighting conditions become less ideal.

Video recording with the main camera tops out at 4K resolution at 30 fps, with electronic stabilization available for smoother handheld footage.

Front camera video recording maxes out to FHD at 30p but is good enough for video calls in our opinion.

Overall, the camera system feels perfectly capable for everyday photography, though it’s clear that battery life and endurance remain the primary focus of this device.

Users prioritizing camera performance above all else will likely find stronger alternatives elsewhere. But for how much this phone costs, image quality is more than serviceable.

OS, Apps and UI

Out of the box, the realme P4 Power runs realme UI 7.0 based on Android 16. The overall experience feels familiar to anyone who has used a recent realme smartphone, maybe even an OPPO or OnePlus.

Animations remain smooth, customization options are plentiful enough, and the software strikes a good balance between functionality and ease of use.

For AI features, our favorites on this device is AI Writer, which is a useful tool for those who need their thoughts written in higher word counts.

While there are still some pre-installed applications present, most can be uninstalled and the overall software experience feels polished enough for daily use. More importantly, the hardware underneath is capable enough to keep everything feeling responsive and fluid.

Additionally, in realme Labs there’s a nifty heart-rate sensor feature that utilizes the optical in-display fingerprint sensor. Since it is a beta feature, we do not recommend using it as a sole means for health monitoring.

Performance and Benchmarks

The brains behind the realme P4 Power is the MediaTek Dimensity 7400 Ultra chipset paired with LPDDR4X memory and UFS 3.1 storage. Our unit is its sole local configuration of 12GB RAM and 256GB of internal storage. And no, storage is not expandable.

As expected, the phone handled our usual tasks for productivity and leisure without issue. Social media browsing, content consumption, messaging, multitasking, and general day-to-day use all felt smooth and responsive.

Gaming performance is similarly respectable.

When playing Genshin Impact, our benchmark for heavy mobile gaming we could optimally run it at the “low” graphic settings with the FPS set to 60.

Pushing it further, we were also able to clock-in some Neverness To Everness (NTE) with graphics set to “Smooth” which is equivalent to “Low” on Genshin, set to 60 fps as well.

For both games, we experienced frame-rate drops here and there but it is still playable, especially for dailies. It just won’t impress those more akin to playing these titles on a flagship device.

In terms of benchmark numbers, the realme P4 Power delivers a solid upper-midrange performance profile.

Its AnTuTu V11 score places it comfortably above the million-point mark, while Geekbench 6 scores for single-core and for multi-core performance show more than enough processing power for everyday tasks and heavier multitasking workloads.

Graphics performance is equally respectable, and storage performance also proved surprisingly quick.

Overall, the P4 Power isn’t trying to compete with flagship gaming phones. Instead, it focuses on delivering a smooth and balanced user experience while maintaining exceptional power efficiency.

Battery

For battery, well this is the entire reason this phone exists. The realme P4 Power features a massive 10,001 mAh silicon-carbon battery.

To put that into perspective, most flagship smartphones today still sit around the 5,000 mAh mark. Wherein the realme P4 Power effectively doubles that capacity without sacrificing too much on the phone’s thickness.

In our PCMark Work 3.0 Battery test, the device lasted an astonishing 29 hours and 54 minutes. That’s nearly 30 hours of continuous workload simulation and easily one of the best battery endurance results we’ve seen from a smartphone in 2026.

And it doubles-down in our standard video loop test, garnering a result of 41 hours and 40 minutes.

Light to moderate users can realistically stretch the device across two to three days on a single charge, while heavier users should comfortably make it through a full day and well into a second before needing to plug in.

So in short, for daily use, battery anxiety is practically non-existent.

For charging the handset supports 80W wired fast charging, 27W reverse-wired charging, and Bypass charging.

With the included 80W charging brick we were able to charge up the device from 0% in an hour and fifteen minutes. And bypass charging allows us to play all day while plugged in, without worrying about battery degradation.

The reverse charging feature is particularly useful given the enormous battery capacity.

It effectively allows the P4 Power to function as a regular power bank, allowing us to charge accessories like earbuds, smartwatches, or even another smartphone when necessary. Just make sure to keep a type-C to C cable with you.

Simply put, if battery life is your highest priority, very few smartphones currently available can compete with what the realme P4 Power offers.

Connectivity

For connectivity, the realme P4 Power includes a full suite of modern connectivity features including 5G, dual-band Wi-Fi, Bluetooth 5.4, NFC, USB Type-C, GPS, and an infrared blaster.

No eSIM support here, but call quality remains clear, while cellular and wireless connectivity proved stable throughout our testing period.
And the inclusion of NFC support is also welcome for contactless payments and accessory pairing.

Conclusion

The realme P4 Power feels like a smartphone built around a single question:

“What if battery anxiety simply stopped being a problem?”

Everything about the device revolves around that idea.

The massive 10,001mAh battery fundamentally changes how you approach daily smartphone usage. Instead of constantly checking battery percentages or carrying around a power bank, the phone simply keeps going.

What’s impressive is that realme didn’t completely sacrifice the rest of the experience to achieve that. The AMOLED display looks excellent, performance is solid, software remains smooth, and the cameras are perfectly capable for everyday photography.

Of course, compromises still exist.

The phone is heavier than most competitors, the cameras aren’t class-leading, and some users may still prefer a slimmer device over extreme battery capacity.

But honestly, that misses the point of what the P4 Power is trying to be. This isn’t a camera-first flagship killer. It’s a battery-first smartphone that happens to do almost everything else surprisingly well.

And for travelers, students, gamers, field workers, content consumers, and anyone who is simply tired of charging every night, that’s a proposition that’s becoming increasingly attractive.
