What the Experts Are Saying?

The Realme 15x is a compelling phone only for those who prefer getting a long battery life on a budget along with a decently fast charging support. This certainly comes at a cost of visual and imaging flair which when coupled with a dated chipset makes the phone a hard sell in the sub Rs 20,000 segment.

Pros

  • Battery lasts really long
  • Average camera

Cons

  • Subpar display quality
  • Bulky build
  • Inferior processor in the segment
  • Pre-installed apps and bloatware

What the Experts Are Saying?

The Realme C55 brings a good spec package at a fairly affordable price, featuring a FULL HD screen with fast refresh rate, a large battery, decent main camera, and a lightweight build. However, the UI is packed with troubling bloatware, the selfie camera is below average and so is the screen brightness. It is a decent option under the budget but there are better one’s out there.

Pros

  • Crystal clear display quality
  • All day long battery life
  • Main camera clicks decent photos
  • Sleek and lightweight build
  • Includes physical fingerprint scanner

Cons

  • LCD panel with low brightness
  • Mediocre performance for the price
  • Average selfie camera

What the Experts Are Saying?

The Redmi 15 is a good budget phone, but its entire identity hinges on its 7,000mAh battery. Beyond that, its offers only a single camera, slow charging speed and an ancient display technology. The smartphone fails to impress in its price segment. The Redmi 15 is ideal for those who prioritise battery and screen size above all.

Pros

  • Exceptional battery backup
  • Good design and feel
  • Segment’s highest refresh rate

Cons

  • Poor outdoor legibility
  • Average display quality
  • Mediocre camera performance
  • No stereo speakers
  • Slow charging speed

What the Experts Are Saying?

The Motorola G67 Power compliments its name with a 7,000 mAh battery that easily goes on for more than a day without charge. It brings the iconic moto design in a durable body and features loud speakers, and understandable camera. However, Moto went with LCD instead of AMOLED, an underwhelming processor and the software support is minimal. So suffice to say that you can find better options out there.

Pros

  • Strong build and design
  • Loud stereo speakers
  • Decent camera
  • Battery extends over a day

Cons

  • Dated LCD panel over AMOLED
  • Average performance
  • Limited software support

Realme P4x in hand in silver colourway

The Realme P4x combines one of the best processors in the segment with a ginormous battery, all in a pretty sleek form factor. It excels at gaming and is capable of lasting two days on a charge. However, the camera performance is average and charging it back up takes a lot of time. If you prioritise speed and stamina over others, it's one of the best value phones you can get right now.

Pros

  • Excellent performance in the segment
  • Great battery endurance
  • Good software experience
  • Surprisingly good build quality

Cons

  • Average cameras
  • Persistent software bloat
  • 144 Hz refresh rate is gimmicky

What the Experts Are Saying?

The Moto G86 Power is an ideal phone for most casual users. It packs a great display, capable processor, big battery, and useful set of cameras. On the downside though, the charging solution is quite slow and it comes with only a year of updates. It’s a value for money buy for the segment, if you can look beyond these limitations

Pros

  • Excellent AMOLED display
  • Powerful chipset in the segment
  • Massive battery backup
  • Decent camera versatility
  • Clean Android experience

Cons

  • Average build quality
  • Slow charging speeds
  • Limited OS support

Slightly extra 💸 but seriously worth it 😍
