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 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 Realme GT 7 packs the right goodies like a high-end chipset, all-around cameras, a pretty good battery life with really fast charging speeds. If we’re to nitpick, thermal management and ultrawide shots could have been better but that’s asking too much from an otherwise well-packaged phone in the segment.

The OnePlus 15R continues the legacy of the R-series by prioritising raw power above all else. It's a powerhouse in disguise as it delivers a top-tier display, immersive speakers, and massive battery life. It's paired with a decent set of cameras that can do the job, and its design won’t win any awards. But if your top priority is gaming, and only gaming, the OnePlus 15R is your best bet at the moment.

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 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 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 Vivo T4 5G packs a big 7300 mAh battery bundled in a premium-looking design and an equally elegant but vibrant quad curved display. But it also compromises on audio quality with a single speaker, issues with the fingerprint scanner and a single main camera at the back. It's a solid option at Rs 20,999 for those who want long battery life, but its cons can't be ignored.

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.
