What the Experts Are Saying?

Poco M7 Plus is the perfect choice if you’re looking for a multimedia focused smartphone. It has a large and bright display, a huge battery, and pretty loud speakers. Other than that, the performance, cameras, and the HyperOS Android skin leave something to be desired.

Pros

  • Standout design
  • Big and bright display
  • Good performance
  • Outstanding battery life

Cons

  • Full of bloatware
  • Okayish cameras
  • Laggy software experience

Moto G57 Power held in hand from the back

The Moto G57 Power delivers excellent battery endurance, a set of capable cameras, a clean software and good performance all at a really affordable price. However, it compromises significantly on the media experience, with a dated LCD panel and average speakers. While the single-year update policy is limited, the phone is still an ideal choice for budget users, and it's easily one of the best sub-Rs 15,000 phones.

Pros

  • Exceptional battery endurance
  • Good performance
  • Attractive vegan leather design
  • Excellent software experience
  • Capable main camera

Cons

  • Subpar display
  • Slow charging speeds

What the Experts Are Saying?

The Oppo A6x is a fairly cheap smartphone, getting right all the basics with a large and fast display, a well rounded operating system, a camera that can record up to 1080p and a large battery capacity. However, the budget restraint does give you a low resolution screen, lackluster performance and cameras. If you can invest more, there are better options available out there.

Pros

  • Big and responsive display
  • Intuitive software experience
  • Main camera can record upto 1080p
  • Supports MicroSD card
  • Massive battery capacity

Cons

  • 720p display resolution
  • Sub par performance
  • Camera quality is okayish
  • UI packed with bloatware

What the Experts Are Saying?

Amidst the ongoing RAM fiasco, the Oppo K14x 5G manages to position itself as a decent offering for its asking price. It brings a good design, a reliable display, a processor and stress-free battery backup. However, the limited storage capacity makes the base model fall behind competition.

Pros

  • Eye-catchy design
  • Big and fast 120 Hz LCD
  • Reliable Dimensity processor
  • Large 6,500mAh battery with fast charging

Cons

  • Misses out on Android 16 out of the box
  • Less storage for price and dated storage generation
  • Inconsistent cameras

What the Experts Are Saying?

The Realme Narzo 100 Lite 5G is a decent midrange device that offers a smooth 144 Hz refresh rate, 720p LCD screen, sufficient performance for the price and extra long 7,000 mAh battery capacity. While the charging speed is slow, and the cameras are not the best out there, you can still consider this device if you are in the market for a budget 5G phone.

Pros

  • Responsive 144 Hz display
  • Main camera clicks decent daytime shots
  • Good performance for the price
  • Long lasting battery life

Cons

  • Realme UI does not feel optimised
  • LCD display instead of AMOLED
  • Lowlight camera quality is poor

What the Experts Are Saying?

The Oppo A5x is a niche budget phone that offers an extended battery with fast charging and an unparalleled software support. It’s intended for those who wish to keep using their phone long-term instead of replacing it every two years. This does come at the cost of losing out on the camera and display front and if that’s what you want on your phone, then you must look at other options.

Pros

  • Capable chipset
  • Massive battery and good charging speeds
  • Exceptional update policy for price

Cons

  • Subpar camera setup
  • Dated display standard
  • Bloatware-filled UI

What the Experts Are Saying?

The Oppo K13x 5G is a good budget smartphone that offers a no-fuss experience. It is suited for students and users on a budget who are looking for reliable 5G connectivity and long battery backup. However, the Oppo K13x may fall short for gaming and multimedia enthusiasts. The same story continues on the camera front; they are average at best.

Pros

  • Fast and smooth display
  • Clean and durable design
  • Excellent battery backup
  • Clicks good selfies

Cons

  • Struggles under heavy load tasks
  • Cameras are passable
  • ColorOS includes bloatware

What the Experts Are Saying?

The Realme P3 Lite is a budget smartphone, offering only the bare minimum when it comes to features. The high refresh rate display, large battery size, and MicroSD card support are some of the highlights, but the low resolution display, average cameras, and an ad-riddled UI make it a decent offering. We suggest you look at other phones at the same price.

Pros

  • Attractive design
  • Fast refresh rate
  • Delivers decent performance
  • Long battery backup
  • MicroSD card support available

Cons

  • Cameras are not up to the mark
  • LCD display is low-res and dull
  • Plagued with bloatware and ads
