realme P4 Power - The 10,001mAh advantage is real

realme Philippines, back in June, introduced the P4 Power, a regular slab smartphone with a 10,001mAh capacity, the biggest in the country yet.

Meet realme P4 Power

Fast-forward to September 2026, and it is still the only commercially available handset with over 10,000mAh. Currently listed at around PHP 23.5K on Shopee (from PHP 25,999 SRP), it might still be the big-battery phone to consider at this price point.

Read on.

The 10,001mAh Titan Battery is LEGIT

As mentioned, the main highlight of realme P4 Power is the 10,001mAh battery. 

This is double the capacity found on mainstream smartphones from Samsung and Apple.

What's even more impressive is just 9.08mm thick, the realme P4 Power is only slightly bulkier than the iPhone 17 Pro Max w/ up to 5,088mAh capacity at 8.75mm. 

How? realme used a third‑generation silicon‑carbon anode material, combined with their most advanced internal stacking process, instead of lithium‑ion, which is now nearing obsolescence.

True extra-long battery life!

In practice, this translates to extra‑long battery life without the bulk. As a secondary smartphone, it can last up to three days under light use or around two days with casual social media activity on a single charge. I rarely needed to plug it in, and whenever I did, there was still enough power left to keep it running almost all the time.

For heavy usage like Genshin Impact gaming, it drains around 9% of the battery per hour in an air-conditioned location. Battery draw is stronger in hotter locations, but the phone's cooling system is good enough to prevent overheating.

Moreover, this is the country's first 10,001mAh phone battery with TÜV Rheinland’s 5‑Star Battery Rating. This simply means that the phone's battery has been certified for temperature resistance, long‑term health, and multiple safety protections.

It's also reinforced with MIL‑STD‑810H military‑grade shock resistance. Unlike most phones limited to around four years of battery health, the P4 Power is engineered to stay reliable for up to eight years.

In my experience, the P4 Power tops up quickly, hitting 30 to 50% in just 20 minutes using its FREE USB-C 80W Ultra Charge brick.

Moreover, it has Bypass Charging that sends power straight to your phone's motherboard instead of passing it through the battery, which lowers heat and protects battery health during heavy gaming. This also means less battery wear over time, since the cell isn't stressed by simultaneous charging and discharging.

Reliable mid-range experiences

AnTuTu and Geekbench 7 scores

Aside from its massive battery capacity, this is a good everyday mid-range phone.

Inside, it has the 4nm MediaTek Dimensity 7400 Ultra SoC, a chip designed for power efficiency without compromising everyday performance. This is paired with 12GB of LPDDR4X RAM and 256GB of UFS 3.1 storage.

Multitasking is generally smooth!

Multitasking is generally smooth, and apps load quickly. It can run basic games like Mobile Legends: Bang Bang at high settings without issue, and it handles heavier titles as long as you dial the graphics down to medium or low—or mix high, mid, and low settings depending on the game.

The software w/ AI tools

This device runs on Android 16 with realme UI 7.0. It also benefits from AI‑driven optimizations that keep the system responsive and adaptive to user habits.

In daily use, this hardware translates into a seamless experience for casual and social media users. Browsing, messaging, and video streaming feel fluid, with no noticeable lag or stutter.

A high-quality display

While I would have liked its display if it were flat, the 6.8‑inch 3D curved AMOLED panel, protected by Gorilla Glass 7i, offers crisp 2800 x 1280 resolution at 453 ppi.

Thanks to its extra‑smooth 144Hz refresh rate and 240Hz touch sampling, the screen feels responsive and immersive whether scrolling through feeds or playing games.

Colors are vibrant, blacks are deep, and motion is silky—making the display a joy to use. I'm genuinely pleased with the quality of this AMOLED panel, even if it understandably lacks the higher‑end LTPO technology found in flagship screens.

This truly elevates the user experience.

One weakness? The speakers aren't stereo. Those who enjoy watching videos without earphones would have appreciated this handset more if it had dual speakers. Otherwise, the sound from its single bottom‑firing speaker is average but not poor. It's serviceable and gets the job done.

Generally okay cameras

High-quality images even in dim conditions

The realme P4 Power 5G comes with a capable dual‑camera setup that delivers surprisingly good results. Its 50MP f/1.8 main shooter with autofocus and OIS captures crisp, detailed shots even up to 2x zoom, making everyday snaps look sharp and vibrant.

Low light 1x

Our early tests also showed that the 8MP f/2.2 ultra‑wide lens with a 112‑degree field of view holds its own, producing consistent color tuning and balanced exposure that complements the primary camera.

Decent in low light

Low light 1x, UW

For cityscapes and low‑light scenes, both lenses manage to deliver images with lively colors and minimal noise, especially when shooting non‑moving subjects. Zoom remains usable up to around 5x, while portrait mode is a mixed bag, which is expected at this price point.

As expected, great in daylight at 2x and 1x

On the video side, the main camera records up to 4K at 30fps with electronic stabilization, while the front camera handles 1080p at 30fps. Quality is decent, good enough for social media lives, family trip clips, and casual vlogging. Creators will get the best results with a tripod and proper lighting, but for everyday use, it is more than serviceable.

Our thoughts

As of writing, the realme P4 Power 5G remains the country's only 10,001mAh smartphone, delivering unmatched endurance in a surprisingly slim frame.

With fast charging, bypass tech, a smooth AMOLED display, and reliable mid‑range performance, this handset is practically a big‑battery champ at its price point.

Weak stereo sound and average cameras are its trade‑offs, but for users who value longevity above all, this is still a solid contender.

For me, it is generally not bad considering phones are getting more expensive due to rising memory and component costs—many similarly priced mid‑rangers offer worse specs and lack the wow factor of this monster battery.

Do you agree?
