What the Experts Are Saying?

The Poco F7 stays true to the flagship killer spirit with a bold design, bright OLED display, excellent performance and 90W fast charging. However, it comes with compromises like a poorly optimised software experience, inconsistent cameras, and a hefty build. If you’re looking for raw performance and gaming is what you do in the sub-Rs 30,000 segment, the Poco F7 is a compelling choice.

Pros

  • Unique design and solid build
  • Great performance
  • Huge battery with fast charging
  • Up to four major Android updates
  • Good for media consumption

Cons

  • Quite Hefty
  • Average cameras
  • Lower than expected battery life
  • Mediocre software experience

What the Experts Are Saying?

The Realme GT 7 packs the right goodies like a high-end chipset, all-around cameras, a pretty good battery life with really fast charging speeds. If we’re to nitpick, thermal management and ultrawide shots could have been better but that’s asking too much from an otherwise well-packaged phone in the segment.

Pros

  • Premium design with IP69 rating
  • Sharp LTPO AMOLED screen
  • Flagship-level performance
  • Balanced all around camera
  • Long battery life and fast charging
  • Extended update promise

Cons

  • Bulky and thick form factor
  • Thermal management can be improved

The OnePlus Nord CE 6 delivers a smooth, reliable everyday experience with a vibrant display, fluid software and exceptional battery life that easily lasts almost two days. It handles multitasking and casual gaming well, though performance isn't class-leading. The design is practical and comfortable, if not particularly distinctive. Cameras perform well in good lighting but can be inconsistent otherwise. If you can overlook these compromises, it's a dependable, fuss-free phone that gets the job done.

Pros

  • Excellent battery life with fast charging
  • Vibrant AMOLED panel
  • Smooth, feature-rich software
  • Comfortable and practical design

Cons

  • Average performance
  • Not great for gaming
  • Inconsistent camera output

What the Experts Are Saying?

The Oppo F31 Pro Plus is a great phone for multimedia. It packs a large, hi-res colour-rich screen, which is also very smooth. There’s also a huge battery, with fast charging support. But that’s all it packs. Beyond that, the chipset and camera here is something that you might usually see in phones under Rs 20,000. So, this one is an easy option to avoid.

Pros

  • Attractive design with IP69 rating
  • Big AMOLED display
  • Huge battery and fast charging

Cons

  • Subpar cameras
  • Underperforming processor for the price
  • Bloatware exists across OS
  • Software support runs short

Realme 16 Pro in hand design showcased

The Realme 16 Pro impresses with excellent battery life, a bright and immersive AMOLED display and a comfortable design that works well for everyday usage. Performance is generally smooth but definitely not the best in the segment and shows occasional slowdowns under heavy loads. The 200 MP camera delivers decent daylight results but struggles with noise and colour inconsistency at night. Overall, it's a solid mid-ranger than excels in endurance, with a few noticeable compromises.

Pros

  • Stunning, bright display
  • Outstanding battery
  • Decent daylight shots
  • Satisfactory design and in-hand feel

Cons

  • Underwhelming low light shots
  • Strange bugs in the UI
  • Average performance

What the Experts Are Saying?

The Oppo Reno 15C is a well-rounded smartphone with a standout design, excellent display, massive battery and durability that adds peace of mind. It tops it off with a reliable point and shoot camera setup and the ColorOS 16 experience adds a premium touch. However, the lack of a more capable chipset, ads and bloatware inside the UI and poor low light performance pulls the Reno 15C a tad behind.

Pros

  • Signature Reno series design
  • Bright and fast AMOLED display
  • Massive 7,000mAh battery
  • Reliable cameras
  • Comprehensive water and dust protection

Cons

  • Processor is dated for the price
  • Ads and bloatware underwhelm ColorOS 16 experience
  • Low light photos and videos lack details

What the Experts Are Saying?

The Xiaomi Redmi Note 15 Pro Plus is a good offering, featuring a stunning display which is perfect for binge-watching content. The Dolby Atmos-tuned stereo speakers add further charm to the experience and the phone can easily last more than a day with its large battery. It can even withstand a drop in the water and the display protection is excellent. However, the cameras and the software experience are nowhere near the best in this category. It is a good phone, but stuck in the wrong segment, since there are better options available.

Pros

  • Rich and vivid display
  • Solid durability
  • Main camera takes detailed photos
  • Dolby Atmos-tuned speakers
  • Large all-day battery
  • Super-fast charging

Cons

  • Below average performance
  • Ultrawide camera is just okay
  • Night time photos appear soft
  • Features multiple bloatware apps
  • Pricing could be better

The Poco X8 Pro continues the series tradition of delivering exceptional performance but with some much-needed upgrades. It now comes in an aluminium and glass chassis, with a water-resistant build, stunning display, large vapour chamber, improved HyperOS 3 experience and 100W fast charging. While the cameras are a let-down, it was never a highlight of this Poco series. So, if gaming is all that you crave, the Poco X8 Pro wouldn't be a let down for you.

Pros

  • Compact glass and metal design
  • Sharp and smooth AMOLED screen
  • Great gaming performance
  • Reliable battery life with fast charging
  • Improved software experience

Cons

  • Cameras are average at best
  • Multiple bloatware apps

Infinix-Note-60-Pro-Featured-Image

The Infinix Note 60 Pro is a capable mid-range phone that gets more right than wrong. Its display is genuinely good, the 6,500mAh battery lasts a day easily, and the phone handles everyday tasks with decent gaming performance. The Active Matrix Display is a fun addition, and the stereo speakers make media consumption enjoyable. However, the camera needs major improvements, and the iPhone 17 Pro-inspired design may not appeal to everyone. At Rs 31,999, it is a well-rounded phone that holds its own in a competitive segment, provided you know what you're signing up for.

Pros

  • Excellent smooth display
  • Strong battery life with fast charging
  • Decent performance for the price
  • Lightweight and comfortable to hold
  • Feature-rich software

Cons

  • Struggles in demanding games
  • Average cameras
  • Only IP64 rating
