Bought iPhone 3GS in white, obviously 16GB, 3 days after the launch. I have it on O2 UK PAYASYOUGO. One of the things i was glad about getting the 3GS was a better battery life. what was i thinking? It's worse than my old 3G! before you ask: - Wi/Fi is turned off. hardly used. - notifications OFF. - vibrate when on silent. ring only (no vibrate) when volume is on at 50-75% - brightness is between 15-20% with auto-brightness ON. - 1422 songs, 17 videos, 149 photos, 18 apps. - listen to music on long journeys or in bed before sleeping. occasionally watch videos and view pictures. use apps regularly. - gprs/edge always on, use 3g when needed. - bluetooth ALWAYS OFF. - location services only ON when needed. - auto-lock: 1 minute. - no push/fetch used or activated. - send about 100 texts a day. that is my settings for general use. the thing is i have my phone fully charged for when i wake up 7-8am and phone is at 10-20% by 10-11pm that night. is this normal? or should i take it back ? always my reception is terrible. well i get 3G on full bars, but sometimes for no reason, all of a sudden my reception will disappear! it will cut off for hours, i have tried restarting iphone, ejecting sim card, restoring phone and changing cellular data settings, but none of this works and i just need to wait hours for it to come back on! its a real pain in the back side when i have payed £428 for this phone! should i take it back for a replacement?
