Best Battery Backup Mobile Phones Under 40000

Poco X8 Power's massive battery delivers excellent backup, while the sharp AMOLED screen, capable main camera, stereo speakers and long software support make the experience well-rounded. The performance and average ultrawide camera are where Poco has cut corners. However, if battery life matters most, these compromises are easier to live with, as this Poco X8 Power doesn't just have power, but it knows how to make it last.

The Vivo T5 Pro stands out with its massive 9,020mAh battery that easily lasts two days, backed by fast charging, a sharp and responsive display and reliable everyday performance. While the camera is decent in daylight, its low-light performance and the lack of an ultra-wide lens hold it back slightly. However, for Rs 29,999, the Vivo T5 Pro is one of the more well-rounded phones in the segment right now.

The Infinix Note 60 Pro is a capable mid-range phone that gets more right than wrong. Its display is genuinely good, the 6,500mAh battery lasts a day easily, and the phone handles everyday tasks with decent gaming performance. The Active Matrix Display is a fun addition, and the stereo speakers make media consumption enjoyable. However, the camera needs major improvements, and the iPhone 17 Pro-inspired design may not appeal to everyone. At Rs 31,999, it is a well-rounded phone that holds its own in a competitive segment, provided you know what you're signing up for.

The OnePlus Nord CE 6 delivers a smooth, reliable everyday experience with a vibrant display, fluid software and exceptional battery life that easily lasts almost two days. It handles multitasking and casual gaming well, though performance isn't class-leading. The design is practical and comfortable, if not particularly distinctive. Cameras perform well in good lighting but can be inconsistent otherwise. If you can overlook these compromises, it's a dependable, fuss-free phone that gets the job done.

Oppo F35 5G might look like a delicate flower, but it is built to weather any storm. It brings a grippy holographic design, IP68, IP69, and IP69K ratings, a smooth AMOLED screen, and a dependable battery that easily stretches into the second day. The single speaker, lack of HDR support, and occasional frame drops while gaming are things that hold it back. But if endurance and durability top your list, the Oppo F35 makes a strong case in the midrange segment.
