Whether you’re on the move or just powering through a long day, having a phone that won’t quit is non-negotiable. So, if battery life tops your wishlist, you’re in luck—we’ve rounded up the top-performing smartphones that go the extra mile, no matter your budget. Time to meet the battery marathoners of the month! Let’s check them out.
Testing Criteria
We didn’t just take battery claims at face value—we put each smartphone through a series of real and synthetic tests to separate the true endurance champs from the rest.
- PCMark Battery Test: Designed to mimic day-to-day tasks, this test helped us gauge how long these devices can actually keep up.
- Charging Time: We also measured how quickly each phone bounces back from 0%.
This lineup includes both fresh 2025 launches and a few 2024 veterans that still pack serious stamina. So, whether you’re eyeing a budget-friendly trooper or a flagship that keeps going well past bedtime, this list has your back.
Best Battery Phone Under Rs 15,000
Redmi 14C
- PCMark Battery Endurance: 27 hours 12 minutes
- Charging Speed: 1 hour 51 minutes (100%)
The Redmi 14C hits the shelves at Rs 9,999 and comes equipped with a beefy 5,160mAh battery—bigger than the one in its predecessor. While it supports 18W fast charging, Xiaomi has generously included a 33W charger in the box.
Now here’s where things get interesting: in the PCMark battery test, this phone clocked an outstanding 27 hours and 12 minutes. That’s the longest runtime we’ve recorded so far—no other phone in our testing has managed to stretch that far.
When stacked against the competition, the Redmi 14C clearly flexes its stamina. It outlasted the Vivo T4x by about 3 hours, and the POCO M7 by nearly 7 hours.
Charging, however, is a more level playing field. Both the Redmi 14C and POCO M7 needed 1 hour and 51 minutes for a full top-up. The Vivo T4x, on the other hand, raced ahead by wrapping up the charge 21 minutes sooner.

Nothing Phone 3a
- PCMark Endurance: 22 hours 20 minutes
- Charging Speed: 1 hour
The Nothing Phone (3a) has confidently stepped into the ring and claimed the crown for the best battery champ under Rs 25,000. And honestly, it’s well-deserved.
In our PCMark battery test, the Phone (3a) clocked an impressive 20 hours and 22 minutes—putting several rivals to shame. Plus, with a 50W fast charger, it took just an hour to juice up completely.
During daily use, it held its ground like a pro. Whether it was snapping photos, scrolling endlessly through socials, or gaming casually, the battery just kept going.
On the contrary, competitors like the OnePlus Nord CE 4 Lite gave up after 19 hours, and the Realme P3 Pro ran out of steam at the 15-hour mark.
When it came to charging, the Realme P3 Pro was marginally quicker by three minutes, but the OnePlus Nord CE 4 Lite lagged behind, taking eleven minutes more.

iQOO Neo 10R
- PCMark Endurance: 23 hours 17 minutes
- Charging Speed: 54 minutes
iQOO’s latest launch, the Neo 10R, has quickly grabbed attention in India—not just for its rapid-fire performance, but also for its impressive stamina.
In our PCMark battery test, the Neo 10R clocked a solid 23 hours and 17 minutes, outlasting the Vivo V50e by over two hours. Meanwhile, the POCO X7 Pro didn’t even hit the 20-hour milestone.
However, when it came to charging, the Neo 10R was the slowest of the trio, taking 54 minutes to go from zero to full. The Vivo V50e shaved off a minute, and the POCO X7 Pro finished the race in 51 minutes flat.
Despite that, the Neo 10R proved to be a reliable daily driver. It comfortably powered through a full day of social scrolling, video streaming, and casual gaming without breaking a sweat.
Have a look at the image below to see how these phones stack up against each other:

In real-world usage, the V50’s battery held up impressively. After a full day of heavy usage—streaming YouTube, downloading apps, bingeing Netflix shows, and taking photos—the battery still sat comfortably at 90% by the end of the day.

In our PCMark battery rundown test, it clocked an impressive 21 hours and 29 minutes—outlasting pricier rivals like the Vivo X200 and OnePlus 13, both of which fell short of the 20-hour milestone.
Charging efficiency is no slouch either. The iQOO 13 went from zero to 100% in just 38 minutes. Interestingly, the Vivo X200 and OnePlus 13 edged it out slightly, completing the charge 7 and 8 minutes quicker, respectively.
When it comes to daily usage, the iQOO 13 proves to be a reliable companion. It breezes through an entire day with ease—even with regular Instagram scrolling and other typical tasks.
