Realme’s latest concept phone puts an end to battery anxiety

Do you still need a power bank in 2025? The answer is mostly yes; they’re an indispensable travel accessory. But with smartphone battery capacities now rivaling some power banks, that question is more relevant than ever. This year has seen a surge in ultra-high-capacity batteries.

Now, Realme is pushing boundaries further with its latest concept smartphone featuring a mammoth 10,000mAh battery. That’s as much battery capacity as some power banks have in 2025! Battery anxiety, who?

Realme unveils concept phone with a massive 10,000mAh battery

Realme’s new concept device features an ultra-high-density silicon anode battery with a 10 per cent silicon content. This is the highest in the smartphone industry, according to the company. With an impressive energy density of 887Wh/L, this battery is designed to deliver extended usage without sacrificing sleekness.

Despite packing such a massive cell, the phone is only 8.5mm thick and weighs just over 200g. The concept aims to eliminate battery anxiety, which has become a major concern for users when purchasing a new smartphone.

To accommodate the large battery, Realme has introduced a ‘Mini Diamond Architecture’, enabling smarter internal space utilisation. This innovation includes what Realme claims is the world’s narrowest Android mainboard, measuring just 23.4mm.

Realme has a strong track record in battery and charging innovations. Past milestones include the 240W fast charging on the Realme GT3 and a 320W concept charging solution.
