I think mine lasts about an hour before it starts dropping the connection.
My cell phone is on 24/7, I have to charge it every 6 to 7 days.
Anecdotally, most of my friends who seem to rely on their phones are constantly running out of charge. It makes me laugh to see commercials where they talk about how you get a zillion free minutes on this plan or that, and my friends are all keeping their calls down to about 30 seconds because they don’t have enough charge…
Nokia phones seem to have the best battery life - Every Nokia I’ve ever had is good for a week of standby, compared to the LG phones they got us for work that drop dead in three days.
I leave mine on most of the time, including nights, and charge it about every 6 days. I expect that to change since it’s now my solitary phone, instead of being mostly used for finding out when the bus will come.
My phone goes for roughly 4 or 5 days. My girlfriend’s can’t last a day.
