What the Experts Are Saying?

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 in hand design showcased

The Oppo Find X9 nails all the essentials and is sleek, durable as well as powerful without feeling bulky. The Dimensity 9500 delivers smooth day-to-day performance and gaming, while the compact display is bright and punchy. The triple 50 MP cameras are the cherry on top and capture some incredible shots. Meanwhile, the massive battery easily lasts a full day. Add ColorOS 16 to that with long-term software support and you've got a near-perfect compact flagship that suffers from certain drawbacks.

Pros

  • Relatively compact form factor makes it comfortable to use
  • Great performance with Dimensity 9500
  • Impressive set of cameras
  • Bright display
  • Phenomenal software experience

Cons

  • Subtle focus hunting issues in videos
  • Lacks LTPO display tech

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

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

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.

Overall, the iQOO 15R is a love letter to gamers that won't disappoint hardcore players.

The OnePlus 15R continues the legacy of the R-series by prioritising raw power above all else. It's a powerhouse in disguise as it delivers a top-tier display, immersive speakers, and massive battery life. It's paired with a decent set of cameras that can do the job, and its design won’t win any awards.

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. While the cameras are just decent and software needs a minor cleanup, it remains a solid pick for those who prioritise battery over anything else. For the price, it's a reliable, long-lasting companion with a few compromises.

What the Experts Are Saying?

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.
