I have an old iPhone4 from 2011 that is not keeping a charge anymore. I'm due for an upgrade but I'm looking forward to still keeping this around for music, photos, etc - plus I still don't have a new phone yet so I can put it to some use in the mean time. I know there are eBay sellers that get rid of used batteries claiming they are new and some people sell new ones that are much more expensive but may not do the trick. Just wanted to see what the consensus was and if any of you have had satisfactory results replacing an iPhone battery. As far as details go, the model of my iPhone is A1349.
