What the Experts Are Saying?

shot of the OnePlus 15 standing upright on a flat wooden surface in front of an off-white background

The OnePlus 15 is a jack of all trades, featuring top-tier performance, high refresh rate display and long battery life. However, it ditches the iconic OnePlus design for a generic look that doesn't have anything special to say about itself. The screen suffers a downgrade in resolution, and the same goes for the build quality and camera. It does not justify its high starting price, especially since there are some fairly good alternatives at lower prices.

Pros

  • Fluid 165 Hz display
  • All-day battery life
  • Top notch performance
  • Feature-rich and smooth software
  • Loud stereo speakers

Cons

  • Phone looks plain and bland
  • AI altered zoom photos

Oppo Find X9 Pro Featured Image with the Phone in Hand

The Oppo Find X9 Ultra is a superhuman in a market full of capable flagships – packing top-of-the-line specifications, incredible performance, and a long-lasting battery. The design turns heads too, and the point-and-shoot-like camera largely lives up to that promise. Its only kryptonite is the aggressive AI processing, which gets in the way of what could have been a more authentic photography experience. At over Rs 1.5 lakhs, the Find X9 Ultra caters to serious camera enthusiasts or those who refuse to settle for anything less than the best.

Pros

  • Elegant and durable design
  • Sharp AMOLED panel
  • Class leading cameras
  • Top notch performance
  • Extremely long battery life

Cons

  • Heavy AI processing in photos
  • Slightly top heavy

The Realme GT 8 Pro is a big improvement over its predecessor, offering actual flagship specs like a 2K display, top-tier cameras, excellent performance and standout battery.

Pros

  • Bright and vivid 2K display
  • Excellent gaming performance
  • Versatile camera setup
  • Enduring battery life
  • Load stereo speakers

Cons

  • Poor build quality
  • UI bloatware exists

Poco X8 Pro Max black back design showcased

The Poco X8 Pro Max is the best thing Poco has ever done with their X series. Flagship-grade performance, a two-day battery and premium build at a mid-range price make it a no-brainer for most people. The cameras and HyperOS 3 still need work, but neither is a dealbreaker. Poco's first Pro Max is absolutely worth your money.

Pros

  • Incredible in-hand feel and design
  • Solid battery backup
  • Stellar performance
  • Fun, customisable RGB light
  • Reliable main camera

Cons

  • Quite bulky
  • Underwhelming ultrawide shots
  • UI is unoptimised and bloat-heavy

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

The iQOO 15R is a solid midrange smartphone that is built with gaming in mind. It delivers excellent performance in even the most demanding games, serving high frame rates, without sweating about overheating. The battery is impressively huge, and can easily last for two days on a single charge, and the software experience is smooth and enjoyable too. However, the cameras are average at best, but they do support 4K 60 FPS videos from both front and back sensors. Overall, the iQOO 15R is a love letter to gamers that won't disappoint hardcore players.

Pros

  • Excellent gaming performance
  • Sharp display with super smooth refresh rate
  • Solid 2-day battery
  • Powerful main camera
  • Smooth and polished software

Cons

  • Ultrawide photos not up to the mark
  • Zoomed photos look soft and dull
  • Bloatware notifications from V-Appstore

shot of the OnePlus Nord 6 standing upright on a desk in front of a blue background

The OnePlus Nord 6 is a performance-focused mid-range phone that excels where it matters the most. The chipset handles everything effortlessly and the display is among the smoothest and sharpest in the segment. The battery life comfortably stretches to two days, while the software feels clean, fluid, and future-proof. Trade-offs include a weak ultra-wide camera and a hefty build but for raw performance and battery endurance, the OnePlus Nord 6 is simply hard to beat at this price.

Pros

  • Solid performance
  • Stunning, smooth display
  • Exceptional battery life
  • Clean, well-optimised software
  • Reliable main and selfie cameras

Cons

  • Ultra-wide sensor disappoints
  • Pretty heavy

The Vivo T5 Pro stands out with its massive 9,020mAh battery that easily lasts two days, backed by fast charging, a sharp and responsive display and reliable everyday performance. While the camera is decent in daylight, its low-light performance and the lack of an ultra-wide lens hold it back slightly. However, for Rs 29,999, the Vivo T5 Pro is one of the more well-rounded phones in the segment right now.

Pros

  • Big, bright AMOLED panel
  • Reliable everyday performance
  • Outstanding battery life
  • Detailed and vibrant daylight shots
  • Solid durability

Cons

  • No 120 FPS in CoD Mobile and BGMI
  • Average low-light photography
  • Filled with bloatware apps and alerts

The Realme P4 Power is unmatched in battery life but also delivers a bright 1.5K AMOLED display, a stylish and sturdy design, as well as dependable day-to-day performance.

For the price, it's a reliable, long-lasting companion with a few compromises.

Pros

  • Massive battery life
  • Bright and smooth AMOLED screen
  • Solid build quality
  • Stable day-to-day performance

Cons

  • Average camera performance

The Realme Narzo 5G is a battery-first smartphone, packing a behemoth 10,001mAh unit which should go on for at least 3 days. It offers a 144Hz display, great levels of water and dust protection, decent everyday performance and an okay-ish main camera. The software experience and build quality aren't that great. But if you are looking for a top-notch battery performance, then the Realme Narzo Power is an easy recommendation.

  • Massive three-day battery
  • Sharp and smooth AMOLED screen
  • Solid IP66/68/69 rating
  • Satisfactory performance
