With the recent purchase of my iPhone 11 Pro Max, I wanted to get a good case. Over the years I have had many cases including a few Mophie battery pack cases. I looked into them again but I remembered they required a mini-USB connector and I didn’t really want to swap out all my other iPhone cables just for the case.
While I have seen a lot of reports of really bad battery life on the iPhone 4S with iOS5 I haven’t seen many articles about battery issues on the iPhone 4. I have had some major battery issues since my upgrade, unplugging my fully charged iPhone 4 at 8:30am not using it through the day it usually ends up at about 12% charge left at 6:30pm.
