Summary
Realme has confirmed it will showcase a slim concept phone with a huge 15,000mAh battery at the Realme Fan Festival on August 27, 2025.
Realme has teased a new smartphone that packs a massive 15,000mAh battery, making it one of the largest battery capacities ever seen on a modern handset. The company will showcase the device during the Realme Fan Festival on August 27, alongside other announcements.
Realme 15,000mAh Battery Record-Breaking Power
Just days after releasing the Realme P4 Pro with a 7,000mAh battery, Realme has confirmed that its upcoming handset will more than double that figure. While the official teaser labeled the capacity as “1x000mAh,” a closer look confirms the actual number: 15,000mAh.
Realme claims this super-sized battery can deliver up to 50 hours of nonstop video streaming on a single charge. The brand also promises an impressive 18.75 hours of continuous video recording, positioning the device as a potential game-changer for creators and heavy media consumers.
Realme Slim Design Despite Heavy Battery
Unlike most rugged or ultra-battery phones, which are typically thick and bulky, Realme’s 15,000mAh phone maintains a slim profile. Early teasers suggest the design will be comparable to the Realme GT 10,000mAh prototype showcased earlier this year, which came in at just 8.5mm thick.
The new model is also expected to utilize ultra-high silicon-content anode battery technology, similar to the GT concept, which helps pack such large capacity into a thinner frame without compromising durability.
Concept Device or Commercial Model?
As with the GT 10,000mAh concept phone, there’s speculation that this 15,000mAh phone may not head to mass production. Realme often uses these concept devices to demonstrate battery innovation and design breakthroughs before refining them for mainstream models.
However, with demand for longer-lasting smartphones on the rise, this teaser may signal Realme’s intention to eventually bring super-sized battery phones to market.
Realme will officially unveil the 15,000mAh concept smartphone at the Realme Fan Festival on August 27, 2025, where we can expect more details about specifications, design, and potential availability.
