Hi, welcome to the forum. There are already several threads about battery life here, so do a quick search & see what tips are suggested. Briefly, my battery lasts 2-3 days easily, BUT it takes time to get to this level. Give the battery a chance to get used to your levels of use & re-charging etc...at least a couple of weeks! 3G is the biggest battery killer, as is Bluetooth & wifi, so try to leave these off when not in use. Widgets that refresh too often also drain the battery, ie/ weather etc...& e-mail accounts or Twitter/Facebook that refresh too often. I have no apps on my Ace to monitor battery life or data usage or task killers, or anything, because the software manages itself & these can actually use battery anyway. Give the Ace a chance & don't forget that also, like the rest of us, you are no doubt still "playing" with the phone non-stop to find out what it can do!!
. Enjoy the Ace it's great, but do give it a chance & do look on here for tips & hints about anything, not just the battery life. I hope this helps. GrahamF. London.
