We are all living in an era where a 5,000mAh battery capacity in smartphones has become the new norm. The trend now is leaning toward even larger batteries, with some phones packing batteries as big as a power bank, all while maintaining sleek, sub-8.5mm designs. As our daily routines increasingly revolve around battery-draining tasks—scrolling through reels, shooting high-res videos, gaming on the go—fast charging is no longer just a nice-to-have; it’s a necessity. No wonder a blazing-fast charging speed has become a necessity for the average Joe, to the extent that some base their purchasing decisions on this very fact. That’s where we have you covered. We have compiled a list of four smartphones under Rs 45,000 that have a battery capacity exceeding 5,000 mAh and charge instantly in minutes. Let’s check them out.

OPPO Reno13:
Battery capacity: 5,600mAh
Charging wattage: 80W
Time taken to charge 0-100%: 44 minutes
The OPPO Reno13 is among the fastest-charging smartphones you can purchase for under Rs 40,000. The 80W SuperVOOC charger-in-the-box requires approximately 44 minutes of your time to fully charge the 5,600mAh battery inside the Reno13 from 0% to 100%.
If design is at the top of your priority list, apart from the ultra-fast charging, the Reno13 perfectly fits the bill. An aluminium frame bolsters its 7.29 mm-thick body, which is sandwiched between two frosted Corning Gorilla Glass 7i glasses. With the camera module raised and surrounded by a halo border, this phone is a true beauty to behold. Regarding the performance, it features the MediaTek Dimensity 8350 SoC, paired with 8GB LPDDR5X RAM and up to 256GB UFS 3.1 storage.

Vivo V50
Battery capacity: 6,000mAh
Charging wattage: 90W
Time taken to charge from 0-100%: 44 minutes
The Vivo V50 takes the same amount of time as the OPPO Reno13 to replenish its battery from 0%, making it another fastest-charging smartphone on this list. But what’s even more surprising about its charging time is that its battery capacity is rated at 6,000mAh, which is 400mAh more than that of the Reno13. Yet Vivo, with some trickery, enabled the V50 to match the pace of the latter.
Aside from its rapid charging, the V50 excels at delivering exceptional battery life. The phone is also a great pick for camera enthusiasts as it captures striking photographs with intricate details. Another thing we like about the phone is its performance. It relies on the Qualcomm Snapdragon 7 Gen 3 processor for performance, and the company has mastered the art of keeping the temperature under control. Therefore, the V50 will operate stably without overheating, even if you attempt to push it to its absolute limit. The smartphone is also equipped with up to 12GB LPDDR5X RAM and 512GB UFS 2.2 storage.

Realme GT 7
Battery capacity: 7,000mAh
Charging wattage: 120W
Time taken for 0-100% charge: 47 minutes
The Realme GT 7 is among the new generation of smartphones that feature the latest silicon-anode battery. With this technology, Realme has integrated a 7,000mAh battery into the smartphone’s 8.3 mm-thick shell. When the battery capacity has reached the power bank’s territory, you may think it will take a millennium to fully charge it from 0% to 100%. It takes just 47 minutes. The GT 7, with its 120W Ultra charger, takes three minutes longer to charge than the OPPO Reno13.
In addition to ultra-fast charging, the GT 7 offers flagship-grade performance and outstanding battery efficiency, enabled by its MediaTek Dimensity 9400e processor. It is also coupled with up to 16GB LPDDR5X RAM and 512 GB UFS 4.0 storage. It did not let us down at all when it comes to clicking pretty photographs in daylight with nearly accurate colours, but we wish we could say the same for the night shots. If fast charging coupled with great performance is what you are looking for, then the Reame GT 7 is a great fit. However, its camera could do with some improvement.

OnePlus 13R
Battery capacity: 6,000mAh
Charging wattage: 80W
Time taken for 0-100% charge: 1 Hour
The OnePlus 13R is the only phone on this list to completely charge its battery in an hour. Yet, it is still a fast-charging smartphone under current standards. In the right condition, you can attain an entire day’s worth of battery life in half an hour.
As the smartphone features the Qualcomm Snapdragon 8 Gen 3 chipset, a year-old flagship processor, you can expect terrific performance. It is also armed with up to 16GB LPDDR5X RAM and 512GB UFS 4.0 storage. Like every phone on this list, its cameras can capture beautiful photographs in daylight conditions. Even its front camera is not far behind in quality. However, the best thing about the phone is its clean UI. If that is a top priority for you, along with the time it takes to charge the phone, then the OnePlus 13R is as good as it gets.
