I am on my second Galaxy Ace in 3 weeks (first one didn't like the Internet). All OK with this one until Saturday - in the morning I could connect to my PC and download some photos using Kies. In the afternoon I learnt how to set up the wi-fi (so much quicker!). Now PC doesn't recognise my phone - Kies cannot find it. Since then battery power is dreadful. I have turned of the wi-fi but today have had to charge the phone 3 times. Fully charged at 7.30am. By 1230 battery was dead (wi-fi had been on) - only received one text. Turned off wi-fi and re-charged. By 2130 (7 hours) needed charging again. Hadn't turned wi-fi or 3G on. Have read to make sure applications like Facebook are turned off. Am I doing something wrong? Lots of things seem to be running in the background. I exit Facebook by using the back button (bottom right of phone) and going back to home screen. Any help gratefully received or going back to my old Nokia 5230!
