Battery life matters to everyone, especially if you’re always on the go. Nobody wants to worry about their phone dying halfway through the day.
But with so many options out there, picking the perfect long-lasting phone can feel like finding a diamond in the rough. That’s why at XpertPick, we’ve done all the hard work for you. Based on our May tests, we’ve rounded up the top smartphones that deliver excellent battery performance across all budgets. Let’s jump in and see which phones made the cut.
Testing Criteria
Battery specifications on paper only tell half the story—we wanted real answers. So, we put each smartphone through its paces with both practical usage and synthetic benchmarks to see which ones truly go the distance.
We started with the PCMark Battery Test, which simulates real-life usage scenarios to measure screen-on endurance. Next, we tracked charging speeds to find out how quickly each phone can go from dead to full.
This roundup brings together the latest 2025 releases and a few 2024 veterans that continue to impress. Whether you’re after a reliable all-day companion on a budget or a premium device that refuses to quit, we’ve got something for every kind of user.
Best Battery Phone Under Rs 15,000
Redmi 14C
The Redmi 14C launched earlier this year, and even now, it continues to stand out for one key reason: battery life. In our latest tests, it delivered the longest battery performance among all the phones we’ve reviewed so far—including some recent 2025 launches.
It features a larger battery than last year’s Redmi 13C, and in everyday use, that translates to nearly two days of usage with light to moderate tasks. That’s quite impressive for a device in this price range.
When compared with others like the Vivo T4x and POCO M7, the 14C topped our PCMark Battery Test. However, the Vivo T4x did charge faster—about 21 minutes quicker—so there’s a trade-off depending on what matters more to you.
| Smartphone | Launch Price | PCMark Battery Test | Charging Speed | Charging Watt |
| Redmi 14C (Winner) | Rs 11,499 | 27 Hours 12 minutes | 1 hour 51 minutes | 18W |
| Vivo T4X | Rs 13,999 | 24 Hours 52 minutes | 1 Hour 30 minutes | 44W |
| POCO M7 | Rs 9,499 | 20 Hours 30 minutes | 1 Hour 51 minutes | 18W |
So, who should buy this device? Well, design-wise, the Redmi 14C brings a fresh look. The large rear camera module draws attention, and the surrounding circular pattern gives it a bit of visual flair. The display offers a smooth experience too, thanks to its 120Hz refresh rate.
That said, the phone isn’t without compromises. The software experience feels a bit dated, and the waterdrop notch is starting to show its age in 2025. Still, if battery life is your top priority and you’re okay with a few minor trade-offs, the Redmi 14C is a reliable option worth considering.
Best Battery Phone Under Rs 25,000
Vivo T4
Vivo T4 may be new to the ultra-competitive under-Rs 25,000 smartphone segment, but it’s already turning heads for one big reason—its gigantic 7,300mAh battery. We pushed this device through an intense day of testing, including benchmark loops, 4K video capture, gaming with BGMI, and more. The result is that it offered 10 hours of uninterrupted endurance.
On the PCMark battery benchmark, it delivered a staggering 25 hours, beating rivals like the iQOO Z10 and OPPO K13. It also came out ahead in charging speed, giving the T4 a clean sweep in battery performance.
| Smartphone | Launch Price | PCMark Battery Test | Charging Speed | Charging Watt |
| Vivo T4 (Winner) | Rs 21,999 | 25 Hours | 1 Hour 5 minutes | 90W |
| iQOO Z10 | Rs 21,999 | 24 Hours 27 minutes | 1 Hour 12 minutes | 90W |
| OPPO K13 | Rs 17,999 | 24 hours 22 minutes | 1 Hour 15 minutes | 80W |
But this phone isn’t just about lasting long. It also delivers a sharp, immersive display that makes movie watching a treat, and the Snapdragon 7s Gen 3 chipset ensures everyday tasks feel smooth and snappy.
However, all that shines gets a little dulled by the software experience, which still needs polish. If that’s not a deal-breaker for you, the Vivo T4 is a battery beast worth serious consideration, especially for users who hate reaching for the charger before bedtime.
Best Battery Phone Under Rs 30,000
iQOO Neo 10R
iQOO has long been praised for its high-performance smartphones, but with the Neo 10R, the brand proves it’s not compromising on battery life either. Launched earlier this year in India, the Neo 10R is quickly making waves for its balance of power and endurance.
Sporting a hefty 6,400mAh battery and 80W FlashCharge support, the Neo 10R is built for heavy users. In real-world use, the battery holds up impressively—even under demanding conditions. Whether you’re gaming, streaming, or multitasking, the phone keeps up without constantly reaching for the charger.
In our PCMark battery test, the device clocked an outstanding 23 hours and 17 minutes—an impressive feat given its high-end internals and UHD display. Charging is no slouch either; it powers up in under an hour, making top-ups quick and convenient.
Want to know how it fares against the competition? Take a look at our comparison table below to see how the iQOO Neo 10R measures up to the Vivo V50e and OPPO F29 Pro in this segment.
| Smartphone | Launch Price | PCMark Battery Test | Charging Speed | Charging Watt |
| iQOO Neo 10R (Winner) | Rs 26,998 | 23 Hours 17 minutes | 54 minutes | 80W |
| Vivo V50e | Rs 28,999 | 21 Hours 8 minutes | 53 Minutes | 90W |
| OPPO F29 Pro | Rs 27,999 | 16 Hours 28 minutes | 1 Hour 22 minutes | 80W |
Beyond battery life, the Neo 10R has more to offer. With strong all-around performance, a modern, sporty design, and gaming-ready capabilities, it’s a compelling choice for power users. The only drawback is that the software still has some growing to do—but for many, that won’t be a deal-breaker.
Best Battery Phone Under Rs 50,000
Vivo V50
In India’s sub-Rs 50,000 smartphone space—often dubbed the premium mid-range tier—buyers aren’t just chasing raw specifications. They’re actually looking for an all-rounder: flagship-grade performance, head-turning design, and most importantly, a battery that won’t quit mid-day.
The Vivo V50 confidently claims its spot as a top performer in battery endurance within this competitive segment.
It’s powered by a beefy 6,000mAh battery and juiced up by 90W fast charging—on paper, it looks good. But in everyday use, it impresses even more. Compared to the Vivo V40, which came with a slightly smaller battery, the V50 offers a noticeably enhanced experience when it comes to battery reliability.
We put it through the wringer: streaming YouTube, bingeing Netflix, loading apps, snapping photos—it was relentless. By nightfall, the battery had barely dropped to 90%. Even under intensive benchmark stress, it held firm at 60%, showing remarkable battery stamina.
Our PCMark test confirmed it—21 hours and 14 minutes of screen-on time. And when it comes to recharging, the 90W FlashCharge takes it from 0 to 100% in just 44 minutes.
Curious how it stacks up against heavyweights like the OnePlus 13R or iQOO 12? Check out our comparison table below to see the numbers side by side.
| Smartphone | Launch Price | PCMark Battery Test | Charging Speed | Charging Watt |
| Vivo V50 (Winner) | Rs 34,999 | 21 Hours 14 minutes | 44 minutes | 90W |
| OnePlus 13R | Rs 39,460 | 19 Hours 38 minutes | 1 Hour | 80W |
| iQOO 12 | Rs 44,999 | 17 hours 55 minutes | 30 minutes | 120W |
But battery isn’t its only strength. The V50 brings ZEISS optics to all its cameras—including the selfie lens—raising the bar for mobile photography in its segment. For shutterbugs, this is more than just a bonus.
While the phone shares design DNA with the Vivo V40, it refines the formula with subtle upgrades. Think of it not as a drastic reinvention but a smarter, more capable continuation—familiar, yet evolved.
Best Battery Phone Under Rs 70,000
iQOO 13
In a market packed with fresh launches, the iQOO 13 still stands tall in the sub-Rs 70,000 segment because of its unbeatable mix of raw power and battery endurance. Despite arriving late last year, this device continues to outpace many 2025 contenders.
It houses a 6,000mAh battery with support for 120W fast charging—and yes, the charger comes in the box. That’s a rare win in today’s market.
In testing, the phone proved rock solid. Benchmarks pulled the battery down from 100% to 78%, which is more than reasonable given the workload. It comfortably lasted through full days of mixed usage—from social media scrolling and media streaming to high-intensity gaming.
Heavy games like Genshin Impact were handled with ease, with a slow and steady battery drain that shows off the phone’s efficient power management. Casual users will find even more headroom.
In our PCMark test, it delivered 21 hours and 29 minutes of screen time, placing it among the top battery performers in this segment. Charging from zero to full took only 38 minutes, keeping downtime to a minimum.
Against rivals like the Vivo X200 and OnePlus 13, the iQOO 13 holds a strong lead in both battery life and performance. Check out our detailed table below.
| Smartphone | Launch Price | PCMark Battery Test | Charging Speed | Charging Watt |
| iQOO 13 (Winner) | Rs 54,999 | 21 hours 29 minutes | 38 minutes | 120W |
| Vivo X200 | Rs 65,999 | 19 Hours 52 minutes | 30 minutes | 90W |
| OnePlus 13 | Rs 69,999 | 18 Hours 28 minutes | 31 minutes | 100W |
The phone retains the design language of the iQOO 12 with subtle refinements. The 144Hz display is fluid, the camera system is capable, and while it could use improvements in low-light and telephoto shots, it’s still a well-rounded offering. The iQOO 13 may not be a radical reinvention, but it nails the essentials with precision, and that’s what counts.
And that wraps up our top battery smartphone picks for May! As newer models hit the market, you can count on us to refresh this list with the latest battery champs. Stay tuned to XpertPick—we’re here to help you cut through the clutter and find out if a phone truly deserves a spot in your pocket.
