Oppo Reno4

The Oppo Reno4 is a line of smartphones developed by OPPO as part of their Reno series. The lineup consists of the Oppo Reno4, Reno4 5G, Reno4 Pro, and Reno4 Pro 5G, serving as the successor to the Oppo Reno3 line. The Oppo Reno4 5G and Reno4 Pro 5G were officially introduced on June 5, 2020.^[1][2] The standard Oppo Reno4 was launched on July 29, 2020, followed by the Reno4 Pro variant on July 31 of the same year.^[3] All models feature fast charging technology; the Reno4 5G, Reno4 Pro, and Reno4 Pro 5G are equipped with a 65W configuration capable of refueling the 4000 mAh battery to 60% in 15 minutes and 100% in 36 minutes.

The Oppo Reno4 Pro was released in India on August 5 in authorized stored, Amazon and Flipkart,^[4] then on October 16 for the United Kingdom alongside Reno 4 and Reno 4 Z.^[5][6]

The front displays are protected by Corning Gorilla Glass 5. For the Reno4 and Reno4 Pro, the chassis build uses plastic materials. The Reno4 5G upgrades its rear plate to Gorilla Glass 3, while the Reno4 Pro 5G implements Gorilla Glass 5 on the back. The midframe elements of both 5G variations are constructed from aluminum.

Looking at physical connectivity on the bottom rim, the 4G iterations include a USB-C port, loudspeaker grille, primary microphone, and a 3.5 mm headphone jack. The 5G iterations replace the audio jack layout on the bottom with a dual-SIM card slot alongside the USB-C interface, loudspeaker, and microphone. A secondary noise-canceling microphone sits on the top edge across all devices. On the 4G versions, the top edge also houses a hybrid expansion tray accommodating either two SIM cards or one SIM combined with a microSD storage card up to 256 GB. Physical volume rockers sit on the left edge, balanced by the power button located on the right.

Color options vary across multiple models:

• Oppo Reno4: Galactic Blue and Space Black.
• Oppo Reno4 Pro: Galactic Blue and Starry Night.
• Oppo Reno4 5G: Galactic Blue, Space Black, and Purple.
• Oppo Reno4 Pro 5G: Galactic Blue, Space Black, White, Pink, and Green.

The 4G entries run on a Qualcomm Snapdragon 720G system-on-chip coupled with an Adreno 618 graphics processing processor.^[7]

The 5G variations shift configurations to a Qualcomm Snapdragon 765G chip platform integrated with an Adreno 620 GPU engine.^[6]

The baseline Oppo Reno4 carries a 4015 mAh battery with 30W VOOC 4.0 fast charging support. All surrounding versions scale down slightly to a 4000 mAh battery capacity while introducing faster 65W SuperVOOC 2.0 charging technology.^[8]

The Reno4 and Reno4 Pro models share an identical quad-camera array - a 48 MP primary wide module with phase-detection autofocus (PDAF) at f/1.7, an 8 MP ultrawide lens at f/2.2, a 2 MP macro sensor at f/2.4, and a 2 MP depth sensor at f/2.4.

The Reno4 5G transitions down to a triple camera structure by removing the dedicated macro node, preserving the 48 MP primary (f/1.7 with PDAF), 8 MP ultrawide (f/2.2), and 2 MP depth sensor (f/2.4).

The Reno4 Pro 5G builds a higher-tier triple camera setup containing a 48 MP main camera (f/1.7) enhanced with Laser AF and optical image stabilization (OIS), a 13 MP telephoto lens (f/2.4) unlocking 2x optical zoom with PDAF, and a wide-spectrum 12 MP ultrawide hardware component (f/2.2) supporting standalone autofocus.

All devices support native video capture modes reaching up to 4K at 30fps. The main camera was integrated with AI Color Portrait, Night Flare Portrait Mode, Ultra Dark Mode, and 960FPS AI Slow-motion AI Color Portrait Video for enhancement.^[9]

The Reno4 5G brings a dual selfie cluster setup forward, containing a 32 MP wide lens at f/2.4 working alongside a 2 MP secondary depth tracking sensor at f/2.4. All companion models in the line carry a singular 32 MP wide module at f/2.4. Front video capture tops out at 1080p at 30fps across the range.

• Reno4: 6.4-inch OLED display at FullHD+ (2400 × 1080 resolution), 411 ppi pixel density, 20:9 ratio, utilizing a singular circular punch-hole cutout for the selfie camera in the top-left corner.
• Reno4 5G: 6.43-inch AMOLED panel at FullHD+ (2400 × 1080 resolution), 409 ppi pixel density, 20:9 ratio, carrying an oblong pill-shaped display cut out to handle its dual lens front hardware.
• Reno4 Pro: 6.5-inch Super AMOLED screen with FullHD+ resolution, 402 ppi pixel density, 20:9 shape profile, featuring a 90 Hz fluid refresh cycle option and HDR10 playback certification.
• Reno4 Pro 5G: 6.55-inch AMOLED screen hitting FullHD+ metrics, 402 ppi density, 20:9 screen ratio, offering a 90 Hz high refresh profile and HDR10+ media support.

Every model in the family implements an optical under-display fingerprint reader solution.

The premium Oppo Reno4 Pro 5G stands out as the only model offering a dual stereo loudspeaker system, which routes channel audio through the baseline frame speaker and ear speaker piece. The remaining line entries rely entirely on single channel mono outputs.
