Battery & Connectivity
We at Gear by MySmartPrice reviewed the Xiaomi Redmi Note 3 back in 2016 and were amazed by the device’s battery performance; it lasted over 2 days even under heavy usage, providing above 8 hours of screen-on time. Now, with the launch for Redmi Note 4, we hope the new device to perform even better. The Xiaomi Redmi Note 4 has a non-removable 4,100 mAh battery. The Xiaomi Redmi Note 4 is capable of accommodating two SIM cards at once, or one SIM card and a microSD card. That means you can’t enjoy the dual-SIM connectivity if you want to use the microSD card. The Xiaomi Redmi Note 4 supports dual-band Wi-Fi ac/a/b/g/n, Wi-Fi Direct, Bluetooth 4.2, GPS (with A-GPS, GLONASS, and BeiDou), IR port, microUSB 2.0 port, and 3.5mm headphone jack.
