I've heard for Samsung, the battery life for their smartphone is not very good, some say 1+ year and it starts acting up. My rule for any phone battery is don't leave your phone on 24/7. You got to shut the phone off some time and let it charge.How long does the battery last in your smart phone?Mine lasts a long time I think. i only charge once every few days. But it depends on your phone. I've seen smart phones with crappy battery life and some with long battery life. You cant do anything to improve battery life except for taking out the battery after turning your phone off (like during school) since battery power is used even when the phone is off.|||I have a Nokia E71 I find the battery lasts around 2-3 while in use.
