Vivo X300 series finally made its way to India today. Comprising at least two models, i.e., X300 and X300 Pro, the phones are powered by Dimensity 9500 SoC, OriginOS 6 out of the box, and up to 1TB storage and 16GB of RAM. X300 brings a ginormous 200MP primary snapper with OIS, 50MP ultrawide, and 50MP periscope telephoto snapper. Moving to the X300 Pro, it changes the camera setup to reflect a 50MP primary sensor with OIS, 50MP ultrawide, and a 200MP periscope lens with OIS.
The Vivo X300 is equipped with a 6,040mAh battery, while the Pro variants get a 6,510mAh battery packed with 40W wireless and 90W fast wired charging tech.
Redmi 15C 5G (India)
Launch Date: December 3
The Redmi Note 15 series is due in India in the coming few days; however, Xiaomi doesn’t want to wait for a few days without a launch, and thus, we have the Redmi 15C 5G on December 3. As the name implies, Redmi 15C 5G is a budget-friendly entry-level device with MediaTek Helio G81 Ultra on the 4G and Dimensity 6300 SoC on the 5G variant.
We have a 6,000mAh battery under the hood supplied with 33W charging tech, up to 128GB of storage, and 8GB of storage. The phone will rival the likes of the Poco M7 series, Samsung Galaxy M17 series, and Vivo T4 series, to name a few.
Specs-wise, the phone has a 6.9” LCD 720p 120Hz panel, 50+8MP rear dual camera, and will be replacing Redmi 14C as a successor available in three colorways — Mint Green, Dusk Purple, and Midnight Black.
Realme P4x 5G (India)
Launch Date: December 4
Realme is launching P4x 5G in India on December 4, and we have some details about the offering so far. The phone will reportedly bring on-board a price tag of INR 15,999/- for the entry-level 6+1258GB variant; the 8+128GB retails for INR 17,499/-, and the highest 8+256GB variant retails for INR 19,499/-.
Realme P4x 5G is powered by Dimensity 7400 Ultra SoC, capable of exceeding AnTuTu scores by 780K. There’s a VC cooling system underneath at 5,300mm² in area, plus a 7,000mAh silicon carbon battery that keeps the phone enlightened for a long time. We have heard about a 144Hz LCD on-board capable of reaching 1,000 nits of peak brightness and 90fps gameplay.
The Realme P4x 5G brings on-board an 8MP front, a 50+2MP dual rear camera, up to 256GB UFS 3.1 storage, 8GB of RAM and 10GB of VRAM, 45W wired charging tech, and a lot more beef to run games such as Free Fire Max and BGMI without breaking a sweat.
OnePlus 15R (India, EU, NA)
Launch Date: December 17
We are literally two weeks away from its launch, and we are already getting to know a lot about the OnePlus 15R. The phone is likely a rebadged OnePlus Ace 6T (China), which is not surprising. The phone brings a premium feel on-board with an affordable price tag that makes it lucrative for users who want to upgrade on a budget.
Specs-wise, we see the OnePlus 15R bring on-board the same flat design as its elder OnePlus 15. There’s an IP69/IP69K rating, a dual-camera setup at the back, and a hefty 8,000mAh+ battery. The phone is powered by the Snapdragon 8 Gen 5, which is a sub-flagship chipset compared to the OnePlus 15’s Snapdragon 8 Elite Gen 5.
The phone bears two colorways, i.e., Fresh Green and Classic Black. The display is likely boasting a 165Hz refresh rate, the most on a sub-flagship phone out there. Apart from this, we have 100W wired and 50W wireless charging support on the go. Do note that these specs should be taken with a pinch of salt, as these are merely rumored and thus, the official specs might differ.
OnePlus Ace 6T (China)
Launch Date: December 3
OnePlus Ace 6T is getting ready for its launch tomorrow in China. As aforementioned, it is basically OnePlus 15R that we will see in India soon.
Redmi Note 15 series (India)
Launch Date: December 2025*
Redmi Note 15 series is coming to India. A value-focused and affordable mid-range series out there, we have Note 15, Note 15 Pro, and Note 15 Pro+ (or call it Note 15 Pro Plus) coming to India sometime in December, as the dates are not out yet.
The trio includes 1250Hz AMOLED panels on board, upgraded camera sensors, faster and better charging, and more. We will see at least 5,500mAh batteries on the trio. On the power train, we have Dimensity 7400 Ultra on the Note 14 Pro and Snapdragon 7s Gen 4 on the Pro+.
Previous reports mention that both Redmi Note 15 Pro and Note 15 Pro+ will carry the same price tags as their predecessors, i.e., INR 24,999/- (for Note 15 Pro 8+128GB) and INR 30,999/- (for Note 15 Pro+ 8+128GB), although we need to wait some more to find out if things have changed.
Oppo Reno 15C
Launch Date: December 2025*
Oppo is adding the third model in its Reno 15 series. Dubbed as Reno 15C, the phone is slated to arrive with a 6.59” 1.5K panel with a refresh rate of up to 120Hz. The phone is powered by Snapdragon 7 Gen 4 SoC, will have a 50MP selfie and a dual rear camera consisting of 50MP Sony LYT-600 and 8MP ultrawide snapper.
Oppo Reno 15C was teased on stage earlier in November when Reno 15 and Reno 15 Pro made their debut in China. It is pretty certain that the Reno 15C, the lowest-end model of the trio, will carry the same design and will be unveiled in China only.
