Nokia 6310ichat_bubble_outlineFrom real comments

Owners consistently highlight the 6310i's extraordinary battery life and longevity. Multiple long-term users report standby times of 5 to 17 days on a single charge, with some still running on original batteries after a decade or more. One user kept a unit powered on continuously for 20 years before retiring it, while another found a phone still working after two years buried under dust and tools, underscoring the phone's reputation for near-indestructible reliability.

Build quality and durability make it a favorite even decades after release. Commenters describe dropping the phone repeatedly, using it daily at work for years, and having it survive damage that would kill modern smartphones. Several still own and use their original units from 2002 to 2004, sometimes keeping multiple as spares or collector's items. This ruggedness, paired with dependable call quality, keeps people returning to it whenever newer phones break down.

Network shutdowns are the main force ending its usefulness, not the hardware itself. Users in the UK and USA note 2G/3G networks are being phased out, forcing owners to retire otherwise-functional phones, while Sweden commenters say GSM/2G still works there for now. This creates a split experience: the phone remains beloved and functional in some regions but is becoming unusable purely due to infrastructure changes rather than any fault of the device itself.
