The OPPO K13 5G is the on-paper pick for a larger battery, higher rated charging speed, UFS 3.1 storage and a stated software-update commitment. The vivo T4R 5G is lighter and lists IP68/IP69 protection, optical image stabilization (OIS) on its main rear camera, and a higher-resolution front camera. Price evidence is not a like-for-like current comparison: OPPO’s figures are April 2025 launch prices, while vivo’s official store displayed ₹22,999 for the T4R 8GB/128GB when accessed.

The listed figures are useful reference points, but they do not establish today’s price gap: the dates differ, and the T4R figure is for one specific variant. Before buying, compare the same RAM and storage tier where available, check seller and stock, and apply any offers consistently. vivo’s listing is on its official India Store comparison page.
Battery, charging and everyday handling
OPPO lists a 7,000mAh battery and 80W SUPERVOOC charging for the K13; vivo lists 5,700mAh and 44W FlashCharge for the T4R. On those specifications, the K13 offers more battery capacity and higher rated charging power. They do not establish how long either phone lasts in real use or how quickly it charges from a particular starting level.

![Lucyliy (3 Pack) Compatible for Oppo K13 5G Screen Protector Tempered Glass，Case Friendly [High definition][Hardness 9H]](https://m.media-amazon.com/images/I/41VbJ6NNdXL._SL160_.jpg)
- Selecting a premium tempered glass screen protector for your mobile phone is like appointing an invisible guardian for your display. It builds a robust defence for your device, ensuring peace of mind with every use.
- Easy to install, problem free, bubble free, easy to install, suitable for your device screen. Easy to apply and disassemble
- This tempered glass screen protector boasts a surface hardness rating of 9H, effortlessly withstanding everyday scratches. Whether you carry your phone alongside keys in your pocket or frequently use your fingernails to operate it, the screen remains smooth and pristine.
- 3 Pack Screen Saver Screen Protector Tempered Glass
- It boasts exceptional drop and impact resistance, crafted from high-aluminium silicate glass and treated with a special tempering process, yielding hardness far exceeding that of ordinary plastic films. Should the phone accidentally fall, the tempered glass screen protector absorbs the initial impact force, effectively dispersing the shock.
The T4R’s listed weight is 183.5g versus 208g for the K13, a 24.5g difference in the manufacturer figures. That may matter if carrying weight is a priority, though the figures alone do not describe how either phone feels in hand.
Durability and cameras
Ingress protection
OPPO lists IP65 for the K13, while vivo lists IP68 and IP69 for the T4R. The T4R therefore has the higher published ingress-protection ratings. These labels should be understood as the manufacturers’ listed ratings, not a promise that either phone is waterproof or will withstand every exposure; the figures do not establish identical test conditions.

- Precise cutouts for improved access to all ports, buttons, cameras, speakers, and mics ensure quick access and feedback to your phone.
Rear and front cameras
The T4R’s published specifications identify OIS on its 50MP Sony main rear camera. OIS can help stabilize camera movement, but the spec alone does not establish overall photo or video quality. The K13 lists a 50MP main rear camera and a 2MP camera; the T4R lists its 50MP OIS main camera and a 2MP bokeh camera. Both list secondary rear cameras, but their stated roles differ.
For selfies, the K13 lists a 16MP Sony IMX480 front camera and the T4R a 32MP front camera. More megapixels do not by themselves prove better image quality; sensor, processing and other factors matter.

Performance, storage and software support
The K13 uses a Qualcomm Snapdragon 6 Gen 4, while the T4R uses a MediaTek Dimensity 7400 5G. OPPO reported a 790,000 AnTuTu score for the K13 in its April 2025 launch announcement; vivo’s product page displays 750,072 for the T4R. These are manufacturer-published figures, and the reviewed pages do not establish comparable independent test methods. They are not a reliable basis on their own for declaring a real-world performance winner.
Both phones offer 8GB/128GB and 8GB/256GB configurations. The T4R also lists a 12GB/256GB option. OPPO specifies UFS 3.1 storage and vivo UFS 2.2; those are different storage standards, but the listing does not quantify the difference users will experience.

Both manufacturers list Android 15-based software: ColorOS 15 on the K13 and Funtouch OS 15 on the T4R. OPPO’s launch announcement states two years of OS updates and three years of security updates. A corresponding T4R update commitment was not confirmed in the reviewed vivo listing, so that should not be read as proof that vivo offers none.
Which phone should you choose?
- Choose the OPPO K13 on paper if your priorities are the larger stated battery, faster rated charging, UFS 3.1 storage, or OPPO’s explicitly stated update commitment.
- Choose the vivo T4R on paper if you value lower listed weight, IP68/IP69 ratings, OIS on the main rear camera, or its 32MP front-camera specification.
- Compare current offers before deciding on price. Match RAM and storage variants, verify the seller and stock, and compare live prices rather than treating a launch price and a later store listing as a current price difference.
Neither manufacturer specifications nor the cited vendor benchmark figures replace independent, comparable testing of battery life, charging time, camera quality, display performance or sustained speed.
