This blog post is based on insights from Manoj Saru‘s YouTube video: “Realme P4 Power 10,001mAh Battery Test on Great Wall of China” featuring special guest Francis.
What if your smartphone could outlast a full day of hiking, gaming, filming, and navigation—without breaking a sweat?
That’s exactly what Realme claims with their new Realme P4 Power, featuring a massive 10,001mAh battery packed into a surprisingly slim body. But here’s the catch: this isn’t just another lab test or benchmark score. Realme took this beast to one of the world’s most challenging locations—the Great Wall of China—for a real-life endurance battle against the iPhone 17 Pro Max.
In this exclusive field test, two tech enthusiasts climbed 10,000 steps while pushing both phones to their absolute limits. GPS navigation? Check. 4K video recording? Check. High-frame-rate gaming? Double-check. The results might just change how you think about smartphone battery life.
What’s Special About the Realme P4 Power?
The World’s Slimmest 10,001mAh Smartphone
When you hear “10,001mAh battery,” you probably picture a brick. But Realme has pulled off something remarkable here.
“This is so slim… I have a 10,000mAh power bank. One side is the phone, one side is the power bank. This phone is even slimmer than that!” — Manoj
The Realme P4 Power isn’t just about raw capacity—it’s about intelligent engineering. While most phones with half this battery size feel bulky, Realme managed to keep the profile sleek enough for daily use. It’s the kind of device that makes you do a double-take when you first hold it.
Key Specifications at a Glance
| Feature | Realme P4 Power |
| Battery | 10,001mAh |
| Display | Quad-curved AMOLED, 120Hz |

The Ultimate Battery Test: Great Wall of China Challenge
Setting Up the Competition
The test was simple but brutal: two phones, one epic location, zero mercy.
Starting battery levels:
- Realme P4 Power: 95%
- iPhone 17 Pro Max: 99%
The challenge? Climb 10,000 steps of the Great Wall while continuously using both devices for navigation, photography, gaming, and video recording. The loser would have to drink a “special” local beverage—talk about high stakes!
“We are going to work from here to the top of the Great Wall—10,000 steps. The phone’s battery is going to take a heavy load. In simple words, it’s going to be tough!” — Manoj
Real-World Testing Conditions
This wasn’t a comfortable office test. The conditions were genuinely extreme:
- Temperature: Around -5°C to 2°C (freezing cold)
- Terrain: Steep, ancient stone steps
- Duration: Over 3 hours of continuous climbing
- Usage: Non-stop GPS, screen-on time, camera work, and gaming
Cold weather is notorious for killing battery performance. If any phone was going to crack under pressure, this was the moment.
Durability Test: Because Accidents Happen
Drop Test Results
Midway through the climb, the Realme P4 Power took an unexpected tumble. And then another. And then another—from even higher.
The result? Completely fine.
“It fell this much… actually, nothing happened. Look, completely fine!” — Manoj
They even conducted intentional drop tests from waist height onto rough stone surfaces. The phone survived without a scratch, showcasing impressive build quality that matches its battery endurance.
Display Quality in Extreme Conditions
The quad-curved AMOLED display with 120Hz refresh rate proved its worth even in bright sunlight at high altitude. The screen remained clearly visible with full brightness, making navigation and photography easy despite the harsh glare.
Gaming Performance: Not Just a Battery Beast
PUBG Mobile (BGMI) Testing
Taking a break from climbing, the team tested gaming performance—and the Realme P4 Power didn’t disappoint.
Graphics Settings Available:
- HDR gaming support
- Smooth to Extreme Plus settings
- 90fps native gaming
- Up to 144fps with HyperMotion
The gameplay was smooth, responsive, and surprisingly immersive for a phone primarily marketed for its battery. The high refresh rate made a noticeable difference in competitive gaming scenarios.
Honor of Kings: China’s Favorite MOBA
To test regional performance, they also ran Honor of Kings—China’s equivalent of League of Legends Mobile. Graphics rendered beautifully, and the five-hero gameplay remained fluid even during intensive team battles.
“Basically, it’s similar to Genshin Impact’s impact… this is high-end gaming.” — Manoj
The Camera Test: 4K Recording Under Pressure
Photography Samples
At around the 7,000-step mark, both phones were put through a camera quality test. The Realme P4 Power captured detailed shots even when zoomed in, with natural color reproduction that impressed the testers.
“Look at the picture quality! If we zoom in and see… what amazing photo quality is coming out!” — Manoj
4K Video Endurance
Here’s where things get interesting. Both phones were set to record 4K video simultaneously—one of the most battery-intensive tasks possible. While the iPhone struggled to maintain charge during this phase, the Realme P4 Power kept trucking, with both front and rear cameras running without overheating or stuttering.
The Final Results: And the Winner Is…
After 10,000 steps, multiple gaming sessions, hours of GPS navigation, and extensive 4K video recording, the results were staggering:
| Device | Final Battery % | Battery Used |
| Realme P4 Power | 66% | 29% |
| iPhone 17 Pro Max | 39% | 60% |
The Realme P4 Power used less than half the battery percentage of the iPhone 17 Pro Max while performing identical tasks. In real-world terms, this means the Realme could likely last 2-3 full days of heavy use, or 4-5 days of moderate usage.
“66% remaining… that’s too much! We need to consume battery faster!” — Francis (during the test, still with plenty of power left)
Hidden Feature: The Power Bank Phone
Here’s a party trick that iPhone users can only dream of: reverse charging.
When the iPhone 17 Pro Max hit 35% battery, the Realme P4 Power—still sitting comfortably at 64%—was used to charge the iPhone wirelessly.
“Let me charge your phone for you… it’s a power bank as well!” — Manoj
This transforms the Realme P4 Power from just a phone into a genuine utility device. Camping trip? Long flight? Festival weekend? Your Realme can keep your friends’ phones alive too.
