Storage and Battery
Internally, the phone offered a mere 16MB of storage, which highlighted the necessity for additional storage through the Memory Stick Duo Pro slot, supporting up to 4GB, considered ample for media files back then. The Sony Ericsson W850 was powered by a removable 950 mAh Li-Polymer battery, accounting for up to 350 hours of standby time and a maximum talk time of 7 hours on 2G networks, adequate for most users' daily needs. However, 3G talk time was notably shorter, reflecting the greater power demands of early 3G technology.
