What Makes the Realme P4 Power Special?

Here’s the headline: The Realme P4 Power packs a massive 10,001mAh battery inside a body that’s slimmer than a standard 10,000mAh power bank. Yes, you read that right.

I had the unique opportunity to test this phone in one of the most extreme conditions possible—climbing 10,000 steps on the Great Wall of China in freezing temperatures (-5 to -6°C), with GPS on, screen on continuously, 4K video recording, gaming, and photography.

If that doesn’t qualify as “real-world extreme testing,” I don’t know what does.

The Ultimate Battery Test: iPhone 16 Pro Max vs Realme P4 Power

The Challenge Setup

My friend Francis (a Great Wall of China expert) challenged me to the ultimate battery showdown:

• Device 1: Realme P4 Power (10,001mAh battery) – Starting at 95%
• Device 2: iPhone 16 Pro Max (standard battery) – Starting at 99%

The Test Parameters:

• Walk 10,000 steps on the Great Wall of China
• GPS navigation on continuously
• Screen brightness at maximum
• 4K video recording simultaneously on both phones
• Gaming sessions (BGMI and Honor of Kings)
• Photography testing
• Ambient temperature: -5 to -6°C

The Results That Shocked Me

After more than 3 hours of intensive use:

• Realme P4 Power: 66% battery remaining
• iPhone 16 Pro Max: 39% battery remaining

Battery drain difference: The Realme P4 Power retained 27% more battery than the iPhone despite having all the same apps running, proving that this massive battery isn’t just a number—it delivers real-world performance.

Design & Build Quality: Slimmer Than a Power Bank

The Impossible Made Possible

When I first held the Realme P4 Power, my immediate reaction was disbelief. How did Realme fit a 10,001mAh battery into a phone that’s slimmer than a standard 10,000mAh power bank?

I literally compared it side-by-side with my power bank, and the phone was noticeably thinner. This is engineering wizardry.

Durability Testing (Because Why Not?)

During our Great Wall adventure, the phone took some serious abuse:

• Multiple drops from waist height on stone surfaces
• Temperature stress (freezing -5 to -6°C conditions)
• Continuous heavy usage for 3+ hours

Result: Not a single scratch, crack, or performance issue. The phone emerged perfectly fine, which speaks volumes about its build quality.

IP68 Water Resistance

The Realme P4 Power comes with IP68 certification, meaning it can handle:

• Dust protection (complete seal)
• Water submersion up to 1.5 meters for 30 minutes
• Accidental spills and splashes

As Francis demonstrated, “You can wash it!”

Display: Premium Quad-Curved AMOLED Experience

Screen Specifications

The Realme P4 Power doesn’t compromise on display quality despite being a battery-focused device:

• Panel Type: Quad-curved AMOLED display
• Refresh Rate: 120Hz (smooth scrolling and gaming)
• Brightness: Excellent outdoor visibility (tested in direct sunlight on the Great Wall)

Real-World Display Performance

Even with screen brightness maxed out during our 3-hour test in bright daylight conditions, the display remained:

• Clearly visible and readable
• Colors remained vibrant
• Touch response stayed accurate
• No noticeable lag or ghosting

The quad-curved design gives it a premium flagship feel that you wouldn’t typically expect from a battery-focused phone.

Performance & Gaming: Not Just About Battery

Chipset & RAM

While the exact chipset wasn’t specified in my testing, the performance metrics speak for themselves:

• BGMI (PUBG Mobile) Gaming:
  • Graphics: HDR, Smooth, Extreme+
  • Frame Rate: Up to 90fps standard
  • Hypermotion mode: Up to 144fps
• Honor of Kings (popular Chinese game):
  • High-end graphics rendering
  • Smooth gameplay with no frame drops
  • No thermal throttling despite extended gaming sessions

Gaming in Extreme Conditions

Here’s what impressed me: We played both BGMI and Honor of Kings in freezing temperatures while the phone was already under heavy load (GPS on, video recording in background).

Zero performance issues. No lag, no stuttering, no overheating (well, it was -5°C, so that helped!).

Camera Quality: Better Than Expected

Photography Testing on the Great Wall

We conducted real-world photography tests in challenging lighting conditions:

Portrait Mode Results:

• Sharp details with good edge detection
• Natural background blur
• Excellent color reproduction

Zoom Capability:

• Digital zoom maintained acceptable quality
• Details remained visible even when zoomed in
• Good clarity for social media and casual photography

Video Recording Performance

The Realme P4 Power handled continuous 4K video recording like a champ:

• Stabilization performed well during walking
• No overheating despite extended recording
• Battery drain was reasonable even with GPS + 4K recording simultaneously

Pro Tip: We recorded continuously for over an hour with GPS active, and the phone maintained consistent performance throughout.

The Power Bank Feature: Reverse Charging

Your Phone Becomes a Power Bank

One of the standout features is reverse wireless charging. When my iPhone 16 Pro Max dropped to 35%, Francis simply placed it on the back of the Realme P4 Power, and it started charging immediately.

Why This Matters:

• Save your friends when their phones die
• Charge wireless earbuds on the go
• Power up smartwatches
• Emergency charging for any Qi-compatible device

With 10,001mAh capacity, you can charge another phone and still have plenty of battery left for yourself.

Battery Life: The Real-World Breakdown

What 10,001mAh Actually Means in Daily Use

Based on our extreme testing, here’s what you can expect:

Conservative Estimate (Mixed Usage):

• 2-3 days of heavy use
• 4-5 days of moderate use
• 7+ days of light use

Our Extreme Test Results: After 3+ hours of:

• Continuous GPS navigation
• Maximum screen brightness
• 4K video recording
• Gaming sessions
• Photography
• Freezing temperatures (-5°C)

Battery remaining: 66%

If this phone can retain 66% battery after that punishment, imagine what it’ll do with your normal daily Instagram scrolling, WhatsApp messaging, and occasional YouTube watching.
