Ive been using a Sony Ericsson Xperia X10 for about a year and a half and it takes a long time to charge. This has been happening for about the last six weeks and getting worse. At this point it hardly charges at all. When plugged in overnight it picks up around 5% charge. While I use the phone quite a bit, I put it into airline mode over night while charging, but still no real gain. While it sounds like a battery issue, I just want to make sure that there isnt some other issue(s) I should check before shelling out the money.
