Sony Ericsson Z520 Memory and Battery

Memory and Battery

Internally, the phone held 16MB of storage, accommodating a phonebook capable of storing 500 contacts with detailed fields and keeping track of up to 30 call records. It didn’t provide an external card slot, limiting its memory expansion. Powered by a removable Li-Ion 900 mAh battery, it promised up to 400 hours of standby time and 9 hours of talk time, making it quite reliable for users who needed durable battery life throughout the day.
