C'mon guys - I guess quite a few of you here already have Samsung Galaxy Ace, right?
Most are complaining about how bad is the battery, how it drains so quickly, right?
But why has no one wrote any NUMBERS and the features, programs used during that time?
You can be saying that the battery is bad - of course is not as good as non-smart phones with smaller (maybe even black&white) screens.
It's obvious that you can't expect to go 1 week without charging.
For some (e.g., me) it's enough if it lasts 2 days.
2 days are actually perfect if I'd have WiFi on during the day (only use it for checking g-mail and maybe a couple of min for web-surfing), use camera for 5 photos, and 1h/day of calls.
That's suitable for me; I don't plan to play games for hours on the phone.
If I use GPS, I use it in my car & charge the phone all the time anyway.
