Battery Life
The standout feature of the BLU Energy X 2 is undeniably its battery life. The phone packs a large 4000 mAh non-removable battery, a rare feature when it was released. This allows for incredibly long standby times of up to 900 hours on a 2G network and respectable talk times, offering up to 52 hours on 2G and 38 hours on 3G. This makes the device a compelling choice for users who need extended battery life, such as travelers or those unable to charge frequently.
