Xiaomi MIUI 7 features Opera Max technology that reduces mobile data consumption by apps by 50%Xiaomi

Chinese smartphone brand Xiaomi, which unveiled the global version of the MIUI 7 ROM on 20 August, has tied-up with Opera to incorporate a feature that reduces data consumption by apps by as much as 50%.

According to a TechCrunch report, Opera Max will compress mobile data usage on cellular and Wi-Fi connections. Opera's data saver technology works on YouTube and Netflix videos as well.

Xiaomi users can enable the Opera Max feature by turning on the Data Saver functionality. Smartphones including the Redmi 1S, Redmi 2, Mi 3, Mi 4i, Mi 4, Redmi Note and Redmi Note 4G can check out the beta version of the MIUI 7 on 24 August.

Other key features of the MIUI 7 include a customised Kids Mode that lets users lock some applications and functions before letting their children use the device. A range of new gender-specific themes are also available in the MIUI 7.

For users who use their phones abroad, the MIUI 7 has introduced MI Roaming, which works like a virtual SIM card, where data packages can be purchased via Xiaomi and users do not have to switch SIM cards on foreign networks.

Moreover, a new feature allows users to set a video to start playing when receiving an incoming call from a certain caller.

The Redmi Note 2 features the MIUI 7 out of the box. The handset is priced at CN¥799 (£79.94) but has the 64-bit Helio X10 processor similar to the HTC One M9+.

The device has a 5.5in screen with 1920x1080 resolution, 2GB RAM, a 13-megapixel rear camera and a 5MP front camera.
