Priced at Rs 8,888, the handset is second in Lava's range of smartphones focussed on longer battery life.
"With smartphones becoming part and parcel of everyday life, battery life has become a matter of concern for smartphone users," Lava International Vice President & Head Product, Navin Chawla told reporters here.
With Iris Fuel 60, the aim is to put an end to the recurring problem of frequent charging which has become quite a norm for smartphone users, he added.
The handset features a 5-inch HD IPS display, 1.3 GHz quad core processor, 1GB RAM and 8GB internal memory (expandable up to 32GB).
With a 4,000 mAh battery, the device sports Android KitKat operating system and can be upgraded to the latest Android Lollipop in future. It has a 10MP rear and 2MP front camera.
"The battery allows users up to 32 hours of talktime on 2G without a need to charge the phone. The phone is also equipped with quick charge technology that restricts the charging time to 3 hours 15 minutes," he said.
The handset also boasts of a "solder-less" manufacturing technology where each component is connected to PCBA via connectors, unlike conventional smartphones where manual soldering is used.
This results in lesser defects and makes it easier for service engineers in case of any fault.
