Battery Life
Arguably the most significant highlight of the BLU Energy M is its battery life. It houses a robust 4000 mAh removable Li-Po battery, which, according to the company, could offer up to 900 hours on standby and up to 52 hours of talk time on 2G networks, and 875 standby hours and up to 38 talk hours on 3G networks. This outstanding battery performance would have been a major selling point, catering to users who spend extended periods away from a charging source.
