is using 2.5D glass on a Redmi smartphone priced below Rs. 10,000. There’s a non-removable 4100mAh battery which is the same capacity as the Redmi 3S’s battery, and is being promoted as one of this phone’s highlights. The phone is powered by an octa-core Qualcomm Snapdragon 435 processor clocked at 1.4GHz. There are three variants of the Redmi 4: one with 2GB of RAM and 16GB of storage; one with 3GB of RAM and 32GB of storage; and finally 4GB of RAM with 64GB of storage. Our review unit had 3GB of RAM and 32GB of storage. The Redmi 4 supports expandable storage using a microSD card (up to 128GB).
You get a 13-megapixel rear camera with f/2.0 aperture, PDAF, and an LED flash. There’s also a 5-megapixel front camera with f/2.2 aperture. The new Redmi 4 will support 4G and VoLTE along with other connectivity options. When two SIM cards are used, only the primary one will allow 4G calls and data while the secondary SIM falls back to 2G calls only.
The phone runs on Android 6.0.1 Marshmallow, with Xiaomi’s MIUI 8.2 skin. This is a stable build which is identical to what we saw on the Redmi Note 4 and Redmi 4A. This means that the Redmi 4 has a lot of software features that we have already seen, including Dual Apps, which lets you create a second instance of any app and supports Facebook, Instagram, Twitter, WhatsApp, and more. The Quick Ball feature lets users assign shortcuts for features. One-handed mode shrinks the display to one corner of the screen so that everything’s easier to reach. The phone also gets a scrolling screenshot feature that will let you take screenshot of an entire Web page. Child Mode lets users lock apps, and Second Space creates a separate profile to help users manage business and personal data on the same device.
This version of MIUI looks cleaner and more polished than previous versions. You can read about the software in more detail in our reviews of the Xiaomi Redmi Note 4 and Xiaomi Redmi 4A.
In keeping with previous Redmi phones, the Redmi 4 also packs lots of preinstalled apps such as Music, Mi Picks, Mi Community, News, Security, Notes, Recorder, and Weather. The Themes app lets users select themes, wallpapers, ringtones, and fonts from a store. There’s also a dedicated Mi Store app on the device through which users can buy Xiaomi products and accessories. We believe that the MIUI interface could become lighter with the removal of some of this bloatware, but not all of them can be deleted and they take up valuable storage space on the device. There are also some preinstalled third-party apps including Amazon, PhonePe Wallet, Flipkart, Facebook, and SwiftKey.
Users will get up to 5GB of free Mi Cloud storage when they sign in with a Mi account, which is additional to the 15GB of free cloud storage that’s offered by Google with every Gmail sign-in.
We were disappointed to see that the Redmi 4 does not run Android 7.0 Nougat, nor did it support Google Assistant at the time of review. On long-pressing the home button, the Now on Tap feature for context-based searches is triggered. Xiaomi says that the Redmi 4 will receiving an update to Nougat, and we might get Google Assistant before that, but no timeline has been promised by the company.
