The under Rs 25,000 smartphone space in India is more crowded than ever—and brands are clearly pulling out all the stops. From the iQOO Z10 and Vivo T4 to the Nothing Phone (3a) and Realme P3, the competition is fierce. So, instead of just reviewing them individually, we put their batteries to the ultimate test. Which one powered through and which one tapped out early? Let’s find it out.
A Look Within
Among the latest releases, the iQOO Z10 and Vivo T4 stand out for one major reason—they both pack a massive 7,300mAh battery, a capacity that’s unmatched in their category so far.
Meanwhile, Realme plays it safe with a 6,000mAh battery in the P3, and the Nothing Phone (3a) sticks to the tried-and-true 5,000mAh, which has become the industry norm.
Inside Our Testing Process
We took these phones to the extreme to test their battery endurance.
First, we played 2 hours of 4K video, followed by an hour of benchmarking. Then, we let the phones rest overnight to track idle battery drain. The next day, we pushed them with 2 hours of 4K video recording, 30 minutes of BGMI gameplay, and another 30 minutes of YouTube Shorts. After a second round of benchmarks, we wrapped up with more 4K video recording until they powered down.
This intense testing method helps us identify which phone is most efficient at different tasks—giving you a clearer picture of how long each device lasts under real-life conditions.
Before testing, we fully charged each phone, maxed out the brightness, enabled auto refresh rate, cleared background apps, and made sure all phones were updated to their latest software version.
So, are you wondering which phone came out on top? Check out our YouTube video for the full breakdown.
