Oppo has launched its new midsegment smartphone, Oppo K13 5G, in India at a starting price of Rs 17,999 (8GB/128GB). The phone comes with several high-end features despite modest pricing. For instance, the phone packs a 7,000mAh battery, a 50-megapixel primary camera and several AI capabilities. It also features a pleasing design and a 6.67-inch AMOLED display. Let's delve deeper into the pros and cons of the Oppo K13 5G in this review by India Today Tech.

While the Oppo K13 5G features a slim profile that easily slips in your pocket, it has a bit of bulk. It measures 8.4mm in thickness and weighs 208g.
It boasts an elegant design, highlighted by a squaoval camera module on the rear, which houses a dual-camera setup. The metallic detailing on the camera island lends the phone a refined, premium feel.

The rest of the back panel maintains a clean, minimalist look with understated geometric accents. The only gripe is that it picks up a lot of fingerprints. Luckily, there is a case in the box.Oppo K13 5G: Big and bright displayThe Oppo K13 5G boasts a large 6.67-inch AMOLED flat display with 120Hz refresh rate. Impressively, the K13 5G's display is bright enough to let me work easily even under the direct sun. It has a peak brightness of 1200 nits (there is no HDR support though). I have also binge-watched Big Bang Theory on the phone and did not feel any discomfort at any given point. In fact, I am impressed with its vivid colours and smooth touch.
The flat display enhances the gaming experience by providing more precise and comfortable control. I did not face any accidental touches. Moreover, the minimal bezels on the Oppo K13 5G's display make the experience more immersive. The phone also has an in-display fingerprint sensor which is fast and reliable.

Oppo K13 5G: Performance and batteryThe Oppo K13 5G is powered by a Snapdragon 6 Gen 4 chipset, coupled with 8GB RAM (LPDDR4X). It runs on ColorOS 15, which is based on Android 15. It comes in two storage variants: 128GB and 256GB (UFS3.1).In my use, I found the Oppo K13 5G to be a fast enough phone that effortlessly handled day-to-day use well. Whether I was scrolling through Instagram, watching YouTube videos, or playing graphically demanding games, it offered smooth performance without any lag. However, switching between apps, or multitasking could be better. I noticed the K13 5G struggle as I juggled between YouTube videos and Instagram DMs.To push the limits, I put the phone under several benchmark tests. On AnTuTu, the Oppo K13 5G scored 6,93,089, while on Geekbench, it achieved a multi core score of 3073 and 1002 for single core, which are decent numbers for a phone at this price.

I typically expect a sub-Rs 20,000 smartphone to last me through the workday—around 10 to 12 hours of usage. However, the Oppo K13 5G has gone above and beyond these numbers. Even after hours of intensive use, including playing demanding games like Call of Duty, streaming Netflix, and listening to music for over four hours, the phone comfortably lasts a full 24 hours on a full charge. I watched 3 episodes of Big Bang Theory on the phone – 1.5 hours – and the battery dropped only 7 per cent (from 97 per cent to 90 per cent.)

The charging speed is also pretty fast. It offers an impressive 80W charging speed, fully charging the device from 0 per cent to 100 per cent in just one hour. In my opinion, the Oppo K13 5G stands out in the sub-Rs 20k segment for its exceptional battery capacity.advertisementOppo K13 5G: CameraOn the photography front, the Oppo K13 5G sports a 50-megapixel primary camera and 2-megapixel depth/portrait camera. The daytime images are quite vivid and bright, but details could be better. While the images are clear (in focus), the camera sometimes struggles to accurately capture the texture/detail of the subject.
The front camera clicks decent images. While it struggles a bit in low light, the selfies will turn out fine if you have ample light in your environment.
Coming to the portrait mode, both rear and front cameras struggle with edge detection, but they are okay for social media posting.

There is one more variant of the phone with 8GB RAM and 256GB storage for Rs 19,999. In fact, it is more than good enough. At this price, the K13 5G hosts a number of premium features including a Snapdragon 6 Gen 4 chip, 7,000mAh battery and an attractive design. There are some areas that could have been better, like for instance, the camera system. If you're looking for a marathon runner that doesn't break your bank, the K13 5G is worth a look.
