The OnePlus N6x is built for buyers who want one thing above everything else: long battery life. Its 7,000mAh battery, clean OxygenOS experience, and durable build make it a practical budget smartphone. At the same time, the phone cuts a few corners. You get an HD+ display, a basic 13-megapixels camera, just 4GB RAM, and slow 15W charging. If those compromises don’t fit your needs, there are several excellent OnePlus N6x alternatives in the same price range. Some focus on cameras, others give you a sharper display, while a few offer much faster charging without asking you to spend much more.
Here’s a closer look at the best options.

Motorola Moto G57 Power
If I had to recommend just one phone instead of the OnePlus N6x, the Moto G57 Power would be my first pick in OnePlus N6x Alternatives. It matches the massive battery while improving almost every other part of the experience.
The phone features a 6.72-inch Full HD+ 120Hz display, which looks much sharper than the N6x’s HD+ panel. Motorola also gives you 8GB RAM as standard, making multitasking noticeably smoother. The 50MP Sony primary camera captures much better daylight shots, and the 8MP ultrawide camera adds extra flexibility.
Charging is another big win. The 7,000mAh battery supports around 30W to 33W fast charging, so you spend far less time waiting.
Why Buy It?
- Same 7,000mAh battery
- Full HD+ 120Hz display
- 50MP Sony camera with ultrawide lens
- 8GB RAM for smoother multitasking
- Faster charging
- Clean Hello UI experience
Things to Keep in Mind
- Slightly older model
- Software update promise is not the strongest
Oppo K14x
The Oppo K14x is another strong OnePlus N6x alternative if your priority is getting better cameras without spending more.
It shares a similar design philosophy with a 120Hz HD+ display and IP64 rating. The big difference comes from the 50-megapixel primary camera. It captures much more detail than the N6x’s 13MP shooter.
Its 6,500mAh battery is a little smaller, but the jump to 45W charging completely changes the experience. A quick top-up takes far less time.
Why Buy It?
- Better 50M-megapixel main camera
- 45W fast charging
- Good daylight display brightness
- Competitive pricing
- Expandable storage
Things to Keep in Mind
- Smaller battery than OnePlus N6x
- ColorOS may not appeal to users who prefer cleaner software

Realme P4R 5G
Battery lovers should definitely look at the Realme P4R 5G. Realme has been focusing heavily on large batteries in its recent budget phones, and this model is one of the best examples.
Depending on the variant, you can get batteries reaching 8,000mAh along with 45W charging. You also get a 50-megapixel camera and high refresh rate display, making it a much more balanced phone than the N6x.
For buyers who travel frequently or stay away from chargers for long periods, this phone makes a lot of sense.
Why Buy It?
- Massive battery
- Faster charging
- Better camera
- Smooth high refresh rate display
- Competitive pricing
Things to Keep in Mind
- Realme UI includes more pre-installed apps than OxygenOS
- Features differ across variants
Vivo T5x
If your budget can stretch slightly beyond Rs 20,000, the Vivo T5x deserves attention.
It offers a larger battery than many others in the similar range. It has stronger processors in some variants, and noticeably better selfie cameras. Vivo has also improved its software over the last few years, giving users a smoother day-to-day experience.
This phone feels like a step up from the OnePlus N6x without entering premium pricing.
Why Buy It?
- Large battery
- Better selfie camera
- Faster chipset
- Good overall performance
Things to Keep in Mind
- Costs slightly more
- Battery is big, but not every variant reaches the N6x’s endurance

Samsung Galaxy M17
Samsung’s M-series continues to be a safe recommendation for buyers who keep their phones for several years.
The Samsung Galaxy M17 may not lead the segment in battery size. However, it offers dependable cameras, reliable build quality, and one of the better software support policies in this price range.
If updates matter more than having the biggest battery, Samsung is worth serious attention.
Why Buy It?
- Reliable software updates
- Good cameras
- Trusted build quality
- Balanced everyday experience
Things to Keep in Mind
- Charging speed is not the fastest
- Battery capacity trails the biggest rivals
Redmi 15C 5G
Redmi has always competed aggressively in the budget market. The Redmi 15C 5G continues that trend.
The battery is slightly smaller than the N6x at around 6,000mAh to 6,500mAh. But the phone gives you stronger overall hardware. Performance, camera quality, and display often feel better than what the OnePlus N6x provides.
For buyers who want more speed without spending extra, Redmi remains a smart choice.
Why Buy It?
- Great value
- Better overall performance
- Good camera quality
- Smooth daily usage
Things to Keep in Mind
- Battery is smaller
- Software includes extra pre-installed apps

Which OnePlus N6x Alternative Should You Buy?
| If Your Priority Is… | Best Phone |
|---|---|
| Best overall balance of battery, display, cameras, RAM, and software | Motorola Moto G57 Power, Redmi 15C |
| Fast charging and better camera quality | Oppo K14x |
| Maximum battery backup | Realme P4R 5G |
| Long-term software support and reliability | Samsung Galaxy M17 |
Your choice depends on what matters most.
Final Verdict
The OnePlus N6x is still a solid choice for users who simply want a huge battery, durable design, and the clean OxygenOS experience. The trade-off is clear though. You get a basic camera setup, an HD+ display, only 4GB RAM, and slow 15W charging.
Among all the OnePlus N6x alternatives, the Motorola Moto G57 Power is the easiest recommendation. It keeps the massive battery while adding a sharper Full HD+ display, much better cameras, double the RAM, and faster charging. But of course, one can have different preferences. Get the one that offers the best value and feels like the more complete smartphone for you.
