Battery Life
Battery performance is where the BLU Grand Energy truly shines. The 4000 mAh non-removable Li-Po battery promises exceptional longevity, with estimated standby times of up to 800 hours on 2G and 720 hours on 3G. Talk time figures are equally impressive, offering up to 52 hours on 2G and 38 hours on 3G. This impressive endurance made the device particularly appealing for users who prioritized battery life and needed a phone that could last days on a single charge under moderate use.
