TL; DR

iQOO India has confirmed (via the official X account) that the iQOO 15R will feature a 7,600 mAh battery.
The iQOO 15R is the “slimmest smartphone” with a 7,600 mAh battery, as it has a side profile of 7.9 mm.

iQOO India has confirmed (via the official X account) that the iQOO 15R will feature a 7,600 mAh battery.

We already have smartphones with over 7,000 mAh batteries across segments, including the Moto G67 Power 5G (Rs. 15,739), Nord CE 5 5G (Rs. 24,999), and the realme 16 Pro Plus 5G (Rs. 39,999).

However, the iQOO 15R is the “slimmest smartphone” with a 7,600 mAh battery. For those catching up, the phone is 7.9 mm thick, making it noticeably slimmer than traditional mid-rangers or flagships, and it packs a 7,000 mAh battery.

How Does The Phone Compare To Other 7,000+ mAh Smartphones?

Below is a comparison of the iQOO 15R with other 7,000+ mAh smartphones and their thicknesses. I’ve included the latest flagship, since it represents the pinnacle of the smartphone industry.

	Battery Capacity	Thickness
iQOO 15R	7,600 mAh	7.9 mm
iQOO 15	7,000 mAh	8.1 mm
OnePlus 15	7,300 mAh	8.1 mm
OnePlus 15R	7,400 mAh	8.1 mm
Realme 16 Pro	7,000 mAh	7.8 mm
Realme GT 7T	7,000 mAh	8.3 mm

It’s interesting that the iQOO 15R will feature a bigger battery than the regular iQOO 15 (review) and still maintain a thinner side profile than the flagship (7.9 mm vs. 8.1 mm). Even the OnePlus 15R (review) had a larger battery than the OnePlus 15 (review), but both phones are equally thick at 8.1 mm.
