In a world where smartphones are getting slimmer and more powerful, battery life still remains a top priority for many users. For heavy gamers, content creators, travelers, or simply those who hate charging multiple times a day, a big battery can be a game-changer. Thankfully, brands are now pushing boundaries, offering sleek devices with massive 7000mAh+ cells without making them bulky.
Here’s a detailed look at the best smartphones with 7000mAh (and beyond) batteries you can get in 2025.
OnePlus has quietly entered the big-battery race with the India variant of the Nord CE 5, packing a generous 7100mAh battery with 80W wired charging. Despite its size, the phone maintains a sleek profile with an IP65-rated body and a large 6.77-inch Fluid AMOLED display supporting HDR10+ and 120Hz refresh rate. Powered by the MediaTek Dimensity 8350 Apex, it offers smooth performance, making it a perfect companion for long days of streaming, gaming, and multitasking.
The Oppo K13 keeps things simple yet efficient. It features a clean 6.67-inch AMOLED panel with 120Hz refresh rate, Snapdragon 6 Gen 4 chipset, stereo speakers, and an IP65-rated build. The 7000mAh battery supports 80W charging, ensuring you spend more time using your phone and less time plugged in. Weighing under 210g, it’s surprisingly light for a big-battery device.
Vivo T4 packs a huge 7300mAh battery with 90W wired charging and 7.5W reverse charging to power accessories like earbuds. Despite the massive cell, the phone remains under 8mm thick. It boasts a 6.77-inch AMOLED display with 120Hz refresh rate, Snapdragon 7s Gen 3 processor, IP65 rating, and 4K video recording capabilities — making it a rare blend of endurance and style.
The Realme 15 Pro combines a 7000mAh battery with lightweight design — just 187g. It’s IP68/IP69 rated, features a stunning 6.8-inch OLED display with 144Hz refresh rate, and packs dual 50MP cameras. Charging speed is 80W, which takes it to 50% in under 30 minutes. If you want a phone that feels premium yet lasts long, this is a top pick.
Positioned as a premium flagship, the Realme GT 7 offers a 7000mAh battery with 120W charging, filling halfway in just 14 minutes. It uses the MediaTek Dimensity 9400e processor, has a 6.78-inch LTPO AMOLED display peaking at a massive 6000 nits, and is IP69 rated. A triple-camera setup with telephoto zoom ensures you get flagship-grade photography alongside marathon endurance.
The Poco F7 takes the crown for the biggest battery here, at 7550mAh in the India variant (6500mAh internationally). It’s IP68-rated, runs the Snapdragon 8s Gen 4 chip, and supports 90W fast charging plus 22.5W reverse wired charging. With a 6.83-inch AMOLED display and performance-focused hardware, it’s ideal for hardcore users who need extreme power backup.
The GT 7T is the “performance plus” sibling of the GT 7, featuring the MediaTek Dimensity 8400 Max chipset, IP68/IP69 water and dust protection, and the same 7000mAh battery with 120W charging. It also offers bypass charging for gaming while plugged in and promises six years of software updates, making it a future-proof choice for tech enthusiasts.
For pure performance lovers, the iQOO Neo 10 delivers with Snapdragon 8s Gen 4 hardware, a smooth 144Hz AMOLED display, and 7000mAh battery with 120W fast charging. With IP65 rating and stereo speakers, it’s a solid choice for gaming and multimedia, offering both raw power and lasting endurance.
Large batteries no longer mean bulky, unattractive smartphones. The latest 7000mAh+ devices combine massive battery life with premium displays, powerful chipsets, water resistance, and flagship-level features. Whether you want a sleek mid-ranger like the Oppo K13, an endurance beast like the Poco F7, or a flagship performer like the Realme GT 7, there’s a perfect match for your needs.
