I want to buy a Samsung Galaxy Ace in a couple of weeks but I have issues with it.?

I have (had) a Samsung Galaxy Ace and tho I really liked the form, functionality, and features, I just chucked it due to battery life. Am a moderate user, I don't do a lot of games or watch videos. I do use social media apps and some browsing. The battery will not last me through the day and I'd find myself avoiding to use the phone for fear that the battery would drain. Would have been good if that had an extra battery for it but it doesn't so for my purpose, it did not fit the bill. Hope this helps.
