Best Battery Backup Mobile Phones Under 40000

The Realme P4 Power is unmatched in battery life but also delivers a bright 1.5K AMOLED display, a stylish and sturdy design, as well as dependable day-to-day performance. While the cameras are just decent and software needs a minor cleanup, it remains a solid pick for those who prioritise battery over anything else. For the price, it's a reliable, long-lasting companion with a few compromises.

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.
