Best Battery Backup Mobile Phones

The OnePlus 15 is a jack of all trades, featuring top-tier performance, high refresh rate display and long battery life. However, it ditches the iconic OnePlus design for a generic look that doesn't have anything special to say about itself. The screen suffers a downgrade in resolution, and the same goes for the build quality and camera. It does not justify its high starting price, especially since there are some fairly good alternatives at lower prices.

The Oppo Find X9 Ultra is a superhuman in a market full of capable flagships – packing top-of-the-line specifications, incredible performance, and a long-lasting battery. The design turns heads too, and the point-and-shoot-like camera largely lives up to that promise. Its only kryptonite is the aggressive AI processing, which gets in the way of what could have been a more authentic photography experience. At over Rs 1.5 lakhs, the Find X9 Ultra caters to serious camera enthusiasts or those who refuse to settle for anything less than the best.

The Realme GT 8 Pro is a big improvement over its predecessor, offering actual flagship specs like a 2K display, top-tier cameras, excellent performance and standout battery. The removable camera deco also brings something new to the table. However, its price makes it a tough sell, given that there are quite a few options in this segment.

The Poco X8 Pro Max is the best thing Poco has ever done with their X series. Flagship-grade performance, a two-day battery and premium build at a mid-range price make it a no-brainer for most people. The cameras and HyperOS 3 still need work, but neither is a dealbreaker. Poco's first Pro Max is absolutely worth your money.

The Oppo Find X9 nails all the essentials and is sleek, durable as well as powerful without feeling bulky. The Dimensity 9500 delivers smooth day-to-day performance and gaming, while the compact display is bright and punchy. The triple 50 MP cameras are the cherry on top and capture some incredible shots. Meanwhile, the massive battery easily lasts a full day. Add ColorOS 16 to that with long-term software support and you've got a near-perfect compact flagship that suffers from certain drawbacks.

The iQOO 15R is a solid midrange smartphone that is built with gaming in mind. It delivers excellent performance in even the most demanding games, serving high frame rates, without sweating about overheating. The battery is impressively huge, and can easily last for two days on a single charge, and the software experience is smooth and enjoyable too. However, the cameras are average at best, but they do support 4K 60 FPS videos from both front and back sensors. Overall, the iQOO 15R is a love letter to gamers that won't disappoint hardcore players.

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.
