Realme P4 Power With 10,000mAh Battery Tested at the Great Wall of China: The Ultimate Real-Life Battery Challenge



           Realme is set to expand its P-series lineup in India with the launch of the Realme P4 Power 5G, expected later this month, with January 29 tipped as the launch date. The phone has already appeared on Realme India’s official website, hinting at an imminent release. It is rumoured to feature a 6.78-inch curved AMOLED display with a 144Hz refresh rate, making it ideal for gaming and multimedia. The device may be powered by the MediaTek Dimensity 7400 Ultra chipset, paired with a HyperVision+ AI chip. A key highlight is its massive 10,000mAh battery with 80W fast charging, reverse charging support, and a balanced weight of around 219 grams.

The Rise of Extreme Battery Phones

Over the past few years, smartphone batteries have slowly improved. From 4,000mAh to 5,000mAh, we saw small jumps. But Realme decided to skip the incremental upgrades and go straight into battery monster territory.

Previously, Realme showcased experimental phones with 10,000mAh and even 15,000mAh batteries, but those were concepts or limited tests.
Realme P4 Power is different.

This is the first 10,000mAh Realme smartphone officially launching in India — and it’s not bulky, rugged, or power-bank-like.

That’s what makes it shocking.

First Look: A 10,000mAh Phone That’s Thinner Than a Power Bank

When you hear “10,000mAh battery,” you imagine a brick. Thick. Heavy. Uncomfortable.

But the first moment you see the Realme P4 Power in hand, that assumption collapses.

Side-by-side with a 10,000mAh power bank, the phone looks:

  • Thinner

  • Lighter

  • More premium

It honestly feels impossible.

Yet there it is — a smartphone with a quad-curved AMOLED display, slim frame, and premium finish… hiding a battery larger than most power banks.

Why Test It at the Great Wall of China?

Realme didn’t choose the Great Wall randomly.

The location is symbolic:

  • Over 10,000 steep steps

  • Cold temperatures (around -5°C to 2°C)

  • Long climbs that drain battery through GPS, screen-on time, and camera use

  • No shortcuts — just continuous walking

If a phone can survive this, it can survive any real-world scenario.

To make things even more interesting, the Realme P4 Power was directly compared against an iPhone 17 Pro Max — one of the most power-efficient flagship phones available.

The Challenge Setup: No Mercy for the Battery

This wasn’t a gentle test.

Both phones were pushed aggressively:

  • GPS always ON

  • Screen ON for hours

  • 4K video recording

  • Photography

  • Gaming (BGMI & Honor of Kings)

  • Cold exposure

  • Accidental drops

  • Climbing 10,000 steps

This is exactly how people use phones in real life — except most of us don’t climb the Great Wall while doing it.

Design & Durability: Built for Abuse

During the climb, the Realme P4 Power was:

  • Dropped on stone surfaces

  • Accidentally knocked during walking

  • Used continuously with sweaty hands and cold air

Despite this:

  • No cracks

  • No display damage

  • No performance drop

The phone handled it like a champ.

This tells us something important: this isn’t just a big-battery phone — it’s a durable daily device.

Display Experience: Bright, Smooth, and Readable Outdoors

The quad-curved AMOLED display with 120Hz refresh rate stood out during the test.

Even under:

  • Direct sunlight

  • Snowy reflections

  • Bright outdoor conditions

The screen remained:

  • Sharp

  • Bright

  • Colorful

  • Easy to read

For navigation, camera framing, gaming, and video recording, the display never felt like a compromise.

Performance Test: Gaming on a 10,000mAh Phone?

Big batteries often mean weak performance — but not here.

BGMI & Honor of Kings Testing

  • BGMI ran smoothly with HDR graphics

  • 90FPS support

  • Even up to 144FPS with HyperMotion

  • Honor of Kings (popular in China) ran without lag

Despite long gaming sessions:

  • No overheating

  • No sudden frame drops

  • No battery anxiety

This shows that Realme didn’t just focus on battery size — they optimized power efficiency.

Camera Test: Surprisingly Solid Results

The Realme P4 Power camera was tested in real conditions:

  • Outdoor photography

  • Zoom shots

  • Portraits

  • Continuous video recording

The results were impressive for a battery-focused phone:

  • Sharp images

  • Good color balance

  • Decent dynamic range

  • Stable video recording

This isn’t a camera-centric flagship — but it delivers reliable, social-media-ready results.

The Battery Test Everyone Was Waiting For

After hours of use:

  • Continuous walking

  • Gaming

  • GPS navigation

  • Video recording

  • Photography

Battery Results:

  • Realme P4 Power: ~66% remaining

  • iPhone 17 Pro Max: ~39% remaining

That’s not just a win.
That’s domination.

Reverse Charging: The Ultimate Power Move

Here’s where it gets ridiculous.

After finishing the entire challenge, the Realme P4 Power still had enough battery to charge the iPhone using reverse charging.

Yes — the phone became a power bank.

This is where the name P4 Power truly makes sense.

Cold Weather Performance: A Hidden Win

Cold temperatures usually destroy battery performance. Phones drain faster, sometimes dramatically.

But despite near-freezing conditions:

  • Battery drain remained controlled

  • Performance stayed stable

  • No sudden shutdowns

This makes the Realme P4 Power ideal for:

  • Travelers

  • Outdoor workers

  • Hikers

  • Long commuters

  • Heavy users

Why This Phone Matters

The Realme P4 Power represents a shift.

It proves that:

  • Big batteries don’t need bulky phones

  • Endurance doesn’t mean ugly design

  • Mid-range phones can outperform flagships in real-life battery use

This phone isn’t trying to beat flagships on camera specs or benchmarks.

It’s doing something more important:
👉 Solving battery anxiety once and for all.

Expected India Launch & Pricing

According to early information:

  • India launch: This month

  • Pricing: Not revealed yet

But if Realme prices this aggressively — as they usually do — this phone could disrupt the mid-range market completely.

Final Verdict: Is Realme P4 Power Worth Waiting For?

If you:

  • Hate charging your phone daily

  • Travel often

  • Game a lot

  • Use GPS heavily

  • Want peace of mind

Then yes — this phone is absolutely worth watching.

The Realme P4 Power isn’t just another smartphone.
It’s a statement that battery life can finally stop being a compromise.
