]]> Samsung is reportedly testing a battery that could change the game for smartphone longevity: a massive 20,000mAh dual-cell unit designed to last an incredible 27 hours with the screen on. However, there’s a catch.

📌 Key Takeaways

  • ✓Samsung is developing a 20,000mAh battery for smartphones
  • ✓The battery promises up to 27 hours of continuous use
  • ✓Durability issues arise after testing
  • ✓More data needed before adoption

What’s in Store?

The new battery is said to be based on silicon-carbon technology and consists of two cells: one at 12,000mAh and another at 8,000mAh, with combined thicknesses of just under 10.3mm. The larger cell alone could outperform current high-capacity batteries from competitors like Honor.

The Longevity Question

Despite promising short-term performance, the battery faces longevity issues. During testing, it reportedly swelled to a significant extent—expanding by 75% in thickness after some charge cycles. This could be a dealbreaker for everyday use, as smartphones need reliable batteries over time.

The source claims that while the battery can survive roughly 960 charge cycles per year, its long-term stability is still unclear. For now, it’s best to take this information with a grain of salt until more concrete data emerges from Samsung.
