Battery life is one of the most critical pillars of the smartphone experience, often determining how reliable a device is. For communication, navigation, payments, work, entertainment, and social media, smartphones have become central to our digital lives, and the need for a dependable battery has never been greater.
A phone with a large battery ensures all-day usage without the anxiety of running out of charge during critical situations. On the other hand, fast charging offers the convenience of quickly topping up the battery when it runs low. Ideally, a smartphone that combines both a big battery and fast charging strikes the perfect balance between endurance and efficiency.
Here are five such smartphones worth considering in May 2025, all priced well within Rs 20,000, that pack big batteries, fast charging, or both to deliver excellent battery life.
iQOO Z10

The highlight of the iQOO Z10 (review) is its 7300mAh battery, one of the largest available in this price bracket. Whether you're gaming, streaming, navigating, or attending back-to-back video calls, the Z10 is built to last well over a full day on a single charge. Complementing the big battery is 90W fast charging, which powers the phone to 100 per cent in just over an hour. The combination of a large battery and fast charging ensures that the iQOO Z10 can easily last for over two days on a single charge.
OPPO K13
Rs 17,999

At the heart of the OPPO K13 5G is its 7,000mAh silicon-carbon battery. This substantial capacity, although not as large as the iQOO Z10's, ensures users can enjoy extended periods of usage, whether it's for gaming, streaming, or navigation.
Complementing this is the 80W SuperVOOC fast charging technology, which can charge the device to 62 per cent in just 30 minutes and achieve a full charge in under an hour. It's an easy pick for anyone looking for a smartphone with great battery life and a seamless software experience.
Realme P3
