Oppo’s slim Reno 4 Pro crams a 4,000-mAh battery under its hood.
Midrange phones have developed a reputation for being boring over the past few years. They often come with overused features and unmemorable names. But Chinese phone-maker Oppo’s new Reno 4 Pro is chipping away at that narrative. The Reno 4 Pro, which launched in India in July, is technically a midrange phone, but it’s packed with features typically found in more fancy flagships. It has a curved 90Hz display, ultrafast charging and a set of stereo speakers. But because it is a midrange phone after all, it does make some sacrifices. The biggest thing missing is 5G capability which, if you’re planning on keeping the Reno 4 Pro for a few years, you’ll want your next phone to have. Oppo says that’s because it wants the phone to “better fit” the countries it’ll be released in.
The Chinese version of the Reno 4 Pro, which does have 5G capabilities, starts for 3,799 yuan or approximately $540 ( £410 or AU$750). In India, it starts at 34,990 rupees, which converts to roughly $470. Pricing for markets outside Asia haven’t been released yet, but expect costs to trend higher in Western countries. After India, the Reno 4 Pro is slated for launch in other parts of Asia as well as select European countries, but will not hit shelves in the US.

A 4,000-mAh battery with ultrafast charging
Oppo has a fixation with ultrafast battery charging, a fixation that’s driven it to develop some of the fastest charging technology in the business. (Its 125-watt charger can apparently juice up phones within 20 minutes.) And it’s increasingly taking this tech, which was typically reserved for higher-end or flagship handsets, to its midrange phones.

The device comes with 65-watt fast charging, known as “SuperVOOC 2.0,” which promises to revitalize its dead 4,000-mAh battery in 36 minutes. For comparison, a standard Apple iPhone charger is 5 watts. I tested it twice and both times it filled up to 99% within that time frame. That isn’t 100%, but it’s close enough and it’s a welcome feature on any phone, especially a midtier one. You can also find this charging tech on the Oppo’s super premium flagship, the Find X2 Pro, but that’ll set you back more than $1,300.
In addition to the speedy charging, Oppo says its power-saving modes are more efficient. When you turn on “Super Power Saving Mode,” you’ll be able to chat on WhatsApp for 90 minutes or make calls for 77 minutes with just 5% of battery, according to Oppo. Meanwhile, the company says that its Super Night Time Standby uses up only 2% over eight hours overnight. I’ll have to test this out myself to determine whether these claims check out.
Oppo’s Reno 4 Pro comes with a speedy 90Hz display.
The Reno 4 Pro has a 90Hz curved display
The 6.5-inch Reno 4 Pro has a gently curved AMOLED display outfitted into an impressively compact and slim phone. It’s one of the lightest and slimmest phones I’ve used in a while, weighing just 161 grams and measuring only 7.7mm thick despite the presence of a large battery under its hood. For comparison, Samsung’s pocketable Galaxy S20 is 164 grams and 7.9mm.
Speaking of the display, it features speedy refresh rates of up to 90Hz. Most phones have a 60Hz display, which means the screen refreshes 60 times a second. A faster screen like the one on the Reno 4 Pro makes animations look smoother, text and images more crisp and offers a generally smooth and immersive experience.

The Reno 4 Pro has a total of 5 cameras
The Reno 4 Pro made it easy to take crisp and vibrant photos. Low light imaging was impressive too. But I’m looking forward to trying the Reno 4 Pro camera system in more depth, including its “Smart Slow Motion feature which can capture 1080p video at a super slow 480fps.
The Reno 4 Pro has four cameras on its rear. The main camera has a 48-megapixel lens, which uses Sony’s IMX 586 sensor. It’s accompanied by an 8-megapixel ultrawide camera, a two-megapixel macro camera and mono camera. On the phone’s front, you’ll find a selfie camera that can take 32-megapixel photos, which is a step down on paper from the Reno 3 Pro that set itself apart with its 40-megapixel selfie photos.
