Battery Life
A removable 2000 mAh Li-Po battery powers the BLU Studio J2, offering decent longevity considering the phone’s hardware specifications. Standby times are impressive, with up to 650 hours on 2G and 550 hours on 3G. Talk time is also respectable, achieving up to 24 hours on 2G and 12 hours on 3G networks. The removable battery design is a practical feature, allowing users to swap out a depleted battery for a spare, extending usability without immediate access to charging facilities.
