π Thinner phones packing huge batteries in 2026
Smartphone batteries are getting noticeably thinner despite larger capacities due to material science advancements. Xiaomi is releasing a Redmi Note 17 Pro Max with a 10,000mAh battery that remains only 8mm to 9mm thick. This shift is powered by silicon-carbon battery technology, which increases energy density significantly. Silicon allows for much higher energy storage than traditional graphite, enabling bigger batteries without bulk. Manufacturers are now focusing on chemistry and internal design rather than just increasing phone size. π
