There was a time when smartphones with 4000mAh or 4500mAh batteries were considered impressive. Then came the 5000mAh era, and many thought that was the sweet spot for battery capacity. But technology doesn’t stop evolving. We saw phones with 6000mAh, and now, surprisingly, a phone has entered the market boasting a massive 7300mAh battery—an unprecedented leap in battery life, especially under a tight budget.
In this article, I’ll walk you through everything you need to know about this phone: its strengths, shortcomings, pricing, design, display quality, performance, and more. If you’re wondering whether this device is the right pick for you, read on. By the end, you’ll have complete clarity to make an informed decision.

A Powerful Battery at an Unbeatable Price
The phone in question isn’t a flagship device, nor does it aim to compete with premium models. But for its price point—under ₹20,000—it’s offering something truly remarkable: a 7300mAh battery packed into a slim, practical design.
Most smartphones with large batteries tend to be bulky and heavy, bordering on uncomfortable for daily use. But here, the brand has managed to strike a delicate balance between capacity and usability. Despite its enormous battery, the phone weighs just around 200 grams. That’s quite an achievement, considering that even some standard phones with 5000mAh batteries weigh the same or more.
This weight balance is achieved thanks to silicon-carbon battery technology—a newer approach that allows manufacturers to cram higher capacity into a smaller space without adding extra weight. For anyone who prioritizes long battery life without sacrificing portability, this phone is a standout contender.
Pricing and Variants: Best Value for Money
The base variant of the phone comes with 8GB of RAM and 128GB of storage. This configuration is typically available for under ₹20,000, and during special sales or online offers, you might snag it for even less.
However, if you’re considering waiting until its price drops below ₹22,000 or ₹23,000, it may not make sense anymore. By then, better options with newer processors or improved cameras might be available. So, if you’re in the market now and battery life is your top priority, this phone is definitely worth considering at the current price.
What’s Inside the Box?
Unboxing the device reveals a fairly standard package. Here’s what you get:
- The smartphone itself
- A Type-A to Type-C charging cable
- A Type-A fast charger
- A transparent protective case (which may yellow over time)
There are no earphones or extra accessories included, which is becoming common practice with many brands today.
Build Quality: Surprisingly Comfortable for Its Size
Given its 7300mAh battery, you’d expect the phone to feel like a brick. But that’s not the case here. The in-hand feel is remarkably balanced. With a weight of around 200 grams, it doesn’t feel overly heavy or cumbersome.
Design-wise, the phone features a curved-edge AMOLED display and a slightly curved back, offering a comfortable grip despite the larger dimensions. Make no mistake—it’s not a compact device. You’ll likely need two hands for comfortable operation, especially during extended use like gaming or browsing.
The back panel is made of plastic, as are the side frames. While some might see this as a compromise, it keeps the weight down and improves durability. In fact, the phone has passed military-grade durability tests, making it resilient against minor drops and shocks.
However, I still recommend using it with a case and adding a tempered glass screen protector on the front for added peace of mind. It also boasts an IP65 rating, meaning it’s dust-resistant and protected against low-pressure water jets—not fully waterproof, but splash-resistant enough for everyday use.
Missing Features: Not Without Flaws
No phone is perfect, and this one’s no exception. Two notable omissions may affect your experience:
- No stereo speakers – The phone only comes with a mono speaker setup. Even if it’s loud enough for casual use, it won’t deliver the depth and richness that stereo speakers provide, especially when watching videos or playing games.
- Average haptics – The vibration feedback is basic at best. In fact, many users may prefer turning off haptics altogether because they don’t add much to the experience.
Another potential drawback is the absence of a 3.5mm headphone jack. If you’re someone who still uses wired headphones or AUX cables, you’ll need to invest in a USB-C adapter or switch to wireless audio.
Display Quality: A Visual Treat
Moving on to the display, the phone sports a Full HD+ AMOLED panel with curved edges, making it feel premium despite the budget tag. The bezels are minimal all around, except for a slightly thicker chin at the bottom.
Notable features of the display include:
✅ HDR10+ support
✅ Widevine L1 certification for HD streaming on Netflix, Amazon Prime Video, and other platforms
✅ 4K HDR playback at 60fps on YouTube
This makes it an excellent choice for multimedia consumption. The colors are vivid, blacks are deep, and viewing angles are solid. Whether you’re binge-watching shows or scrolling through social media, the screen delivers impressive quality.
Brightness levels are also commendable. The phone offers up to 1300 nits (HBM) and a peak brightness of 5000 nits (though the latter is achievable only in controlled lab conditions, not real-world usage). Outdoor visibility is solid, and there’s PWM dimming support for reduced eye strain in low light.
The only downside? The display protection is Schott Xensation glass, which isn’t as scratch-resistant as Gorilla Glass Victus or similar. Therefore, I strongly recommend applying a quality tempered glass from day one.
Fingerprint Scanner and Security
Under the display lies an optical fingerprint sensor, which performs fast and reliably. Throughout testing, it unlocked the phone securely without noticeable lag or errors.
Software and Performance: Smooth for Everyday Use
While this phone may not be equipped with a flagship-level processor, it still delivers dependable performance for daily tasks. Multitasking, app switching, and light gaming run smoothly thanks to its 8GB RAM and optimized UI.
Of course, if you’re planning to play high-end games at maximum settings or handle video editing on the go, you might find its chipset a bit lacking. But for WhatsApp, Instagram, YouTube, streaming, and general productivity, it holds up just fine.
The phone ships with Android 13 out of the box, with a fairly clean interface and minimal bloatware. Regular security updates are promised, though it’s unclear how long major Android updates will be supported.
Camera Setup: Decent for the Price
On the camera front, the phone offers a triple-camera setup on the back, led by a 64MP main sensor, accompanied by a 2MP macro and a 2MP depth sensor. There’s also a 16MP selfie camera up front.
Photo quality in daylight is impressive for its segment, producing sharp images with good color balance. However, low-light photography suffers, and night mode can only do so much to compensate. If you’re a casual photographer who mainly snaps photos outdoors or in well-lit environments, this phone will suffice.
Video recording is capped at 1080p at 30fps, which is a limitation for content creators who might prefer 4K recording. Stabilization is electronic (EIS), and while it works okay for casual use, don’t expect pro-level smoothness.
Battery Life: The Star of the Show
Let’s circle back to what makes this phone truly special: its unmatched battery life.
With 7300mAh under the hood, you can easily expect 2 to 3 days of moderate use without needing to recharge. Even heavy users—those gaming, watching videos, and staying on mobile data—will likely squeeze out a full day and more.
Charging isn’t blazing fast compared to flagship standards, but 33W fast charging ensures you’re back to 100% in a reasonable time frame (around 2 hours from zero).
For anyone tired of carrying a power bank or constantly worrying about battery percentage, this phone offers genuine peace of mind.
Final Verdict: Who Should Buy This Phone?
✅ Buy this phone if you:
- Prioritize battery life above all else
- Want a large, vibrant AMOLED display
- Are looking for a budget-friendly media consumption device
- Need a phone that lasts days on a single charge
- Don’t mind plastic build and mono speakers
❌ Skip this phone if you:
- Care deeply about flagship-level cameras
- Want stereo speakers or a 3.5mm headphone jack
- Plan to do heavy gaming or multitasking
- Need 4K video recording
In the end, this smartphone delivers exceptional battery life in an affordable package, making it ideal for students, travelers, or anyone who hates carrying chargers and power banks. While it’s not perfect—missing stereo speakers and having average haptics—it makes a compelling case for itself purely on endurance and display quality.
If you can live with its compromises, it’s one of the best big-battery smartphones under ₹20,000 today.
Final Thoughts
Smartphone evolution has come a long way. From 4000mAh to 5000mAh to now 7300mAh, brands are pushing boundaries to address real user needs. This phone proves that battery capacity doesn’t have to come at the cost of usability.
Sure, it’s not for power users or photographers, but for the average person who simply wants a phone that keeps going, it ticks most of the right boxes.
So, if your top priority is longevity, streaming, and basic daily performance, this phone might be the budget beast you’ve been waiting for.
