The phone includes a built-in vibrator alert, which is hands down the weakest example I have ever seen. Even placed directly on the palm of my hand, I had considerable trouble telling that it was vibrating. This horribly anemic vibrator is backed up by one of the industry s worst ringers. Only one of them is even vaguely loud enough to be useable. That practically wipes out any advantage to being able to assign different rings to various phone book entries.
Battery life is excellent with the standard battery.
Samsung claims 2.5 hours of talk time, and up to 150 hours of standby time. The build quality on the phone is excellent, and it puts the Motorola Timeport to shame. The phone has a rock solid feel that makes you believe you could do anything to it without inflicting any damage. Build quality is perhaps one of the phone s greatest assets. The menu layout in the 8580 is great, and it is arguable just as good as the menus found in the Nokia 61xx phones.
