I'm trying to understand what has happened and I can't really make much sense of it. I bought my iPhone 5s this past April, so it is not that old... Well a couple of months after buying the phone, I installed several apps. I'm not sure which apps I had installed, but there were a few TCP/IP apps like ping apps and general I.T. apps. Well ever since installing those apps, the battery in my phone has been losing its charge extremely fast. I will take the phone off the charger and even if I don't use the phone at all (and no apps are running), after an hour, the battery will be down to like 75% and continues to drop very fast after that... Is it possible that those apps that I installed could cause this to happen or do you think its just a faulty battery in the phone? I went to my cell phone carrier and explained the situation and they sent me a new iPhone 5s... The thing is... I have a ton of photos, apps, contacts, email accounts, etc.. that I have backed up, HOWEVER, I do not want to restore a backup IF those apps are what caused my first iPhone's battery to fail. Can someone help me with this? Do you think it is safe to restore that backup so I don't have to spend hours reloading everything or do you think its best to just do a clean "install"?
