On both the 2.4GHz and 5GHz bands, there’s a full set of a/b/g/n/ac Wi-Fi standards. Hotspot, Wi-Fi Direct, and DLNA media sharing on supported devices are also present. There is also Bluetooth 4.2 and a USB Type-C port for charging, data sharing and also for USB host scenarios.


A non-removable 3000mAh Li-Ion battery with a dash charging tech powers the OnePlus 3. The battery supports 66 hours of endurance rating and calls time of almost 32 hours.

iPhone 7


It has a 4.7″ multi-touch IPS display technology. The screen has a resolution of 1334 x 750 pixels with a typical contrast ratio of 1400:1 and 326ppi. The screen supports the 3D Touch. Its maximum brightness is about 560nits. But on auto, and in bright light, it will shoot to 660 units. The Retina HD display is also 25% brighter. It’s equipped with the Night Shift mode for adjusting colors in the screen display to reduce blue light exposure to the eyes.


The iPhone 7 supports faster LTE Cat. 9 and depending on the model, the LTE band coverage is generally wider. It also supports all 2G (GSM/EDGE) and 3G (UMTS/HSPA+/DC-HSDPA) connectivity network bands. Unfortunately, it doesn’t support the dual Sim functionality.
