OnePlus 13, Xiaomi 15 and Samsung Galaxy A56 lead battery‑endurance race; Android users advised on hidden power‑saving ​

A review of three high‑endurance smartphones highlights the OnePlus 13, Xiaomi 15 and Samsung Galaxy A56. The OnePlus 13 carries a 6000 mAh battery, offers 100 W wired charging and up to 61 hours mixed‑use runtime. The Xiaomi 15, with a 5400 mAh cell and a 90 W charger, records the longest measured endurance at 63 hours and benefits from a 3 nm chipset for efficiency. The Samsung Galaxy A56 includes a 5000 mAh battery, 45 W charging and a more modest 44‑hour mixed‑use span, but its battery is rated for 2000 charge cycles. All three meet IP‑rating standards (OnePlus and Xiaomi IP68, Galaxy A56 IP67).

An Android‑focused guide points out a little‑known system setting that can improve battery life by limiting background activity. It notes that the average 2026 smartphone now carries about 5 291 mAh, a 400 mAh rise from the previous year. Users are encouraged to review the Battery > Usage screen to spot high‑draw apps, and to disable or restrict those that run continuously in the background, such as streaming, navigation, and messaging services.
