Huawei just announced its P40 series on Mar. 27, after its predecessor P30 series impressed us a lot no matter in the incredible cameras or never-ending battery life. Huawei P40 family features three devices: the Huawei P40, Huawei P40 Pro, and Huawei P40 Pro Plus. On the whole, Huawei P40 series is the most incredible handsets Huawei has ever designed, which comes with an eye-catching OLED display, a huge battery, IP68 water- and dust-proof grade, the amazing camera system for tons of shooting possibilities and much more. Despite so many updated features, some people like me may be wondering whether P40/P40 pro would keep some old-school features like IR blaster and NFC.
Does Huawei P40/P40 Pro have IR blaster?
Yes, but not exactly. Huawei P40 Pro and P40 Pro Plus both feature an IR blaster, but P40 doesn’t come with one. Similarly, P40 also lacks an IR depth sensor and ToF sensor, and doesn’t support wireless charging. If you want to buy a “P” handset, is it necessary to increase the budget and have at least a P40 Pro just for the sake of the IR blaster? Better not. Actually, it is a technology existed on smartphones for years. A phone with IR blaster can work as a universal remote, allowing you to control various electronic devices in your home, such as television, set-top box or stereo. However, now more and more manufacturers like Samsung have ditched IR blaster and use voice control instead — take Pixel for example, all the Pixel phones are equipped with a hub called Home Control, which enables you to manage your smart home devices straight from Google Assistant. IR blaster is more popular in Asian countries, including Huawei P30 Pro, Xiaomi Mi9, and Huawei Mate 20 Pro.
So how about NFC?
All Huawei P40 series support NFC (Near field communication). It’s a method of wireless data transfer that detects and then enables technology in close proximity to communicate without the need for an internet connection. You can use it to quickly share content between digital devices, pay bills wirelessly or even use your cellphone as an electronic traveling ticket on existing contactless infrastructure already in use for public transportation. NFC has four modes, reader/writer, peer-to-peer, card emulation and wireless charging. Now Huawei handsets support the former three, but the wireless charging is yet to be developed. Some people may think that NFC is of high similarity with Bluetooth, but compared with Bluetooth, the connection between two Bluetooth devices is rather quick, under a 1/10 second. And because of that, NFC is able to provide a higher degree of security than Bluetooth — as correlating a signal with its transmitting physical device becomes barely possible.
