Battery Life
Powering the device was a removable Li-Ion 920 mAh battery, offering a stand-by time of up to 245 hours and a talk time of up to 4 hours and 10 minutes. Given the phone's feature set and display specifications, this battery life was reasonable, allowing users to go through a typical day without frequent recharging.
Despite its cancellation, the BenQ-Siemens E52 provides a glimpse into the transitional period of mobile technology where functionality began to include multimedia elements, even before the rapid advancements in smartphone technology. Its design and features, while basic by today's standards, were reflective of consumer needs and technological capabilities at the time.
