Battery Life
Perhaps one of the standout features of the XOLO Era 4K was its remarkable battery life, courtesy of a non-removable 4000 mAh Li-Ion battery. The device offered an impressive standby time of up to 624 hours on 2G and up to 528 hours on 3G, along with a talk time of up to 32 hours on 2G and up to 17 hours on 3G. This made it particularly suitable for users needing long-lasting power without frequent recharging.
