I have read everywhere from here to apple.com about the battery issues on both the 4 and the 4s. But my question is this, is anyone having a problem getting a full charge? Or even a normal charging cycle? My iPhone 4, since the upgrade on Wednesday, has not only not fully charged to 100% but it charges at about 2% every hour. 2%!!! Has anyone run into this? Has anyone come up with a solution?
