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 Poco F7 stays true to the flagship killer spirit with a bold design, bright OLED display, excellent performance and 90W fast charging. However, it comes with compromises like a poorly optimised software experience, inconsistent cameras, and a hefty build. If you’re looking for raw performance and gaming is what you do in the sub-Rs 30,000 segment, the Poco F7 is a compelling choice.

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 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 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 Narzo 5G is a battery-first smartphone, packing a behemoth 10,001mAh unit which should go on for at least 3 days. It offers a 144Hz display, great levels of water and dust protection, decent everyday performance and an okay-ish main camera. The software experience and build quality aren't that great. But if you are looking for a top-notch battery performance, then the Realme Narzo Power is an easy recommendation.

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 Neo 10 packs a serious punch, offering a stunning AMOLED display, powerful performance, and an excellent battery life in the mid-range segment. The cameras are dependable and the design feels premium, but Funtouch OS is the only thorn in its side. Still, at the end of the day, this is a performance-first device that nails gaming, multimedia experience and battery endurance.

The Oppo Find X9 Pro is almost the best flagship experience you could ask for. It has a stunning design, a fancy but robust build quality, an array of excellent cameras, strong performance and long-lasting battery life that blows the competition out of the park. The software experience is also very strong, and so are the baked in AI features. Besides some minor issues, it is an excellent device that is well worth the purchase.

The iQOO Z10 brings good upgrades over its predecessor with an exceptional battery, responsive display and a capable main camera. However, it misses the mark with a lacklustre, average quality of materials used and lack of usable secondary cameras. Overall, it’s a good buy if you want a phone for basic media consumption that also runs for long.
