Realme Phone With 10,001mAh Battery Leaks After Honor’s 10,000mAh Launch

The smartphone battery race is heating up fast. Just one day after Honor launched its 10,000mAh Win series, a new leak suggests that Realme may have quietly taken the lead — by the smallest possible margin.

A leaked Realme smartphone is said to feature a 10,001mAh battery, making it one of the largest batteries ever seen in a mainstream smartphone.

What Has Leaked So Far

According to the leak:

• The phone is an unnamed Realme device
• Model number: RMX5107
• Spotted running Realme UI 7.0
• Configuration shown:
  • 12GB RAM
  • 256GB storage
• Already certified for Hi-Res Audio
• Currently undergoing regulatory approvals in Russia

This strongly suggests the device is closer to launch, not just a lab prototype.

Timing Is Not a Coincidence

The leak surfaced just a day after Honor’s announcement, making the timing particularly interesting.

Honor’s Recent Battery Push:

• Honor Win & Win RT
  • Both feature 10,000mAh batteries
  • Focused on endurance over slim design
  • Target users who want multi-day battery life
• Honor Power 2
  • Launch confirmed for January 5 (China)
  • Battery size: 10,080mAh
  • Styled like an iPhone 17 Pro lookalike

Honor is clearly betting big on ultra-large batteries, and Realme seems ready to respond.

Realme’s Battery Roadmap (So Far)

Realme has been preparing for this move for months:

• May: Showcased a 10,000mAh battery prototype
• Announced plans to:
  • Launch a 7,500mAh phone first
  • Follow it with a 10,000mAh model
• Current Realme phones:
  • Max out around 7,000mAh
  • Including the GT 8 Pro

The appearance of RMX5107 suggests Realme’s 10,000mAh-era phone may finally be close.

Why This Is Now Possible

The shift is being driven by:

• Silicon-carbon battery technology
• Higher energy density without extreme thickness
• Makes 6,000–7,000mAh batteries common
• 10,000mAh is now the next milestone

Who Are These Phones For?

Ultra-big battery phones make sense for:

• Frequent travellers
• Outdoor users
• People tired of carrying power banks
• Users who prioritise battery life above everything else

They may not appeal to users who want:

• Slim designs
• Flagship-grade cameras
• Ultra-fast charging

What’s Next?

• Realme has not confirmed launch timelines
• No official markets announced yet
• The leak feels strategic, not accidental

For now, Realme technically leads the battery chart — even if it’s just by one extra milliamp-hour.
