The OnePlus N6x delivers all the essentials of a budget smartphone. The build quality is sturdy, and the 120 Hz display coupled with OxygenOS keeps the daily experience smooth.

Overall, it remains a good pick if you want a phone for basic daily needs but also prioritise extended battery life.
Pros
- Solid build quality and premium finish
- Strong battery endurance
- Smooth 120 Hz screen
- Main camera captures natural-looking daylight shots
- Decent performance for the price
Cons
- Slow charging speed
- Selfie photos are average at best

What the Experts Are Saying?
Vivo T5 Lite 5G lures you in with its sleek design, dependable battery life, and fast charging, but daily use quickly exposes its true colours. It moves at a sloth's pace, stuttering through basic tasks like opening apps and multitasking. To make matters worse, the pre-installed bloatware spams you with relentless alerts like a possessive ex. In a fiercely competitive sub-Rs 20,000 segment, this is one phone you should steer clear of.
Pros
- Strong battery life and fast charging
- Clean design with good in-hand feel
- Customisable Dynamic ring light for alerts
- Main camera takes decent daylight shots
Cons
- Slow, laggy day-to-day performance
- Over 15 pre-installed apps
- Selfie camera over-brightens skin tones
