Other reports of a 6000mAh battery and a huge 200MP primary camera may highlight that Xiaomi aims for portability, photography and efficiency as the biggest factors.Expected specificationsExpected specificationXiaomi 18 FoldFoldable displayAround 7.6-inchDesignWide-format book-style foldableProcessorXiaomi Xring O3, 3nmRAMLPDDR6Operating systemHyperOS 4, based on Android 17Primary cameraRumoured 200MPBatteryRumoured 6,000mAhWired chargingRumoured 67WWireless chargingRumoured 50WFingerprint sensorSide-mountedLaunchSeptember 2026, ChinaThe wider design could be particularly important because traditional book-style foldables often compromise on the proportions of their cover and inner screens. The Xiaomi 18 Fold therefore appears designed to improve usability rather than simply increase specifications.6,000mAh battery targets longer foldable enduranceBattery capacity could become one of the Xiaomi 18 Fold’s strongest selling points. According to tipster Bald Panda, the handset is expected to feature a 6,000mAh battery, paired with 67W wired charging and 50W wireless charging. If accurate, that would give Xiaomi a notable advantage among wider-format foldables, where battery capacity remains an important consideration because larger displays can consume more power.The reported capacity would also put the Xiaomi 18 Fold ahead of several established rivals. The Samsung Galaxy Z Fold 8 is reported to have a 4,880mAh battery, while Huawei’s Pura X View is listed with a 5,300mAh unit. Other foldables, including the Vivo X Fold 5 and Oppo Find N6, have reached the 6,000mAh class, although their designs differ from Xiaomi’s wider format.For Xiaomi, the larger battery could help offset the power demands of a high-refresh-rate foldable display and flagship processor. However, the final battery technology, efficiency and real-world endurance will only become clear after launch.Rumoured 200MP primary camera raises imaging ambitionsPhotography is another area where Xiaomi could attempt to push the 18 Fold beyond conventional foldable specifications. However, the handset is allegedly supplied with the main 200MP back-facing camera, together with the triple-camera system indicated by leaks in prior months. The camera housing as seen has a Horizontal configuration, and the increased body width renders the handset visually distinctive from earlier Mi Mix Fold models. The claimed 200MP resolution figure remains unattested by Xiaomi, making this a report rather than an authoritative assertion.
