Performance and Battery Life
The E2152 provides stable performance for the basic texting, calling, and minor internet browsing it was built for, with Java MIDP 2.0 support enabling the use of simple applications and games. It includes pre-installed social media shortcuts such as Facebook and Twitter, integrating early online social networking to a degree. Powering these features is a 1000 mAh Li-Ion battery, which promised a remarkable stand-by time of up to 660 hours and up to 11 hours of talk time when fully charged—an impressive lifespan demonstrating the energy efficiency of feature phones.
