Battery Life
Powered by a removable Li-Ion 1000 mAh battery, the Nokia 3120 Classic delivers up to 290 hours of standby on a 2G network, which drops slightly for 3G use. Talk time on 2G can reach 3 hours and 30 minutes, while it is somewhat less on 3G, hitting approximately 2 hours and 45 minutes. This battery performance was quite competitive at its launch, offering reliability and convenience for users who were constantly on the go.
