Even though there were many options in the smartphone market, it felt like large battery development had stopped. Almost every phone had a maximum capacity of 5000mAh or 5500mAh at best.
However, all that changed in 2025 when smartphone manufacturers started bringing out phones with Silicon Carbon battery. This new battery technology allows manufacturers to pack in large capacities, such as 6000mAh, 7000mAh, or even higher.
If you are someone like me who hates charging phones every day, then you are in luck. In this article, I'm showcasing some of the best phones with a large battery. Read on to learn more.
Best phones with a large battery
1) Oppo Find X9 Pro

Price: ₹72,999
The Oppo Find X9 Pro is one of the best flagship phones you can buy right now. It has all the best technologies in the smartphone market. It comes equipped with an ultimate camera system, and its periscopic telephoto camera easily beats the Samsung Galaxy S24 Ultra in zoomed shots.
Moreover, the Oppo Find X9 Pro also beats the Samsung phone in battery life. It has a large battery of 7,500mAh capacity, which will last two-to-three days on a single charge with light to medium usage. Even with a bit of heavier usage, the phone should still last two days. When you run out of battery life, the 80W fast charger will quickly fill it up.
2) OnePlus 15

Price: ₹72,999
The OnePlus 15 is the company's best phone to date. Not only does it look stunning, but it's also super strong. The glass back features a special etching with a Micro-Arc Oxidation ceramic layer, making it almost impossible to get scratched. If metallic keys touch the rear glass, it's the key that will get scratched and not the glass.
It may seem weird, but it's true, and third-party reviews have proven the scratch-resistant properties of the rear glass. This phone also has a robust camera system that beats the similarly priced Samsung Galaxy S25 in many scenes.
The OnePlus 15 is also equipped with a 7,300mAh battery, which can last three days or even more with light usage. Even when this large battery ends, the 120W wired fast charging and 50W wireless fast charging will take care of it.
3) POCO F7

Price: ₹30,999
The POCO F7 is designed to deliver one of the best gaming performance capabilities on a budget. This phone is equipped with a high-end 6.83-inch AMOLED panel, which can display accurate colors, high brightness levels, Dolby Vision, and 3840Hz PWM for a flicker-free experience.
This phone also packs the largest battery on this list. Its 7,550mAh battery will run for many days on a single charge. Even if you manage to run out of battery, the POCO F7 supports 90W fast charging, which can fill it back up in under an hour.
4) iQOO Z10

Price: ₹22,999
If you are on a bit of a tighter budget, the iQOO Z10 is for you. Despite costing under ₹23,000, it still has a 7,300mAh battery, which will provide you with the large battery experience you need. It is also paired with 90W fast charging for when you do run out of juice.
The iQOO Z10 also has a decent Snapdragon 7s Gen 3 processor, which will keep your gaming needs satisfied. You will also find a large AMOLED screen, which can display accurate colors, inky deep black levels, higher contrast, and more for a great viewing experience.
5) iQOO Z10x

Price: ₹14,999
The iQOO Z10x is the cheapest phone on this list with a large battery. As such, there are some compromises. It is equipped with an IPS panel, which may not deliver the same viewing experience as an AMOLED display, but it's not that bad. The Mediatek Dimensity 7300 will also take care of your gaming needs.
The 50MP rear camera can also capture some decent shots with good detail levels and color tone. However, the best part of this phone is its 6,500mAh battery, which is actually amazing. Due to the inclusion of a lower-power CPU and a large battery capacity, the iQOO Z10x can also last two-to-three days, just like the other phones on this list.
The Oppo Find X9 Pro and OnePlus 15 will obviously deliver the best experience, but the POCO F7 is not bad either at the ₹31,000 price range. For those on a tighter budget, the iQOO Z10 and Z10x have large batteries to deliver multiple days of power. You will never have to worry about the battery life with these phones.
