First, let me say that I am very happy with my iPhone 5. At some point, I will upgrade to an iPhone 6. The iPhone makes me more productive in my work and my personal life.
About three to four weeks ago, my iPhone battery was draining power very fast. Sometimes, it seemed like it was dropping 1% per minute. In addition, it always felt hot. Not warm; but hot. I could feel it burning in my hands and in my pockets.
One time, I charged it to 100%. I enabled airplane mode and disabled most settings. It maintained 100% charge for 1 hour. Then I turned off airplane mode and let it sit without doing anything. It automatically connects to my WiFi. After 30 minutes, the charge was down to 85%. I enabled Location Services and went for a 5K run. I listen to music while running. I also use MapMyRun to record my run. My run takes about 30 minutes. An hour after seeing the charge was at 85%, the charge was down to 18%.
A few days later, I deleted my Exchange account on my iPhone. The company I worked for was upgrading mail and I thought that might be a problem. That seemed to solve the heat problem a little bit. I also turn off Bluetooth whenever I am not using it. I set the display Brightness to about 50%. Finally, I installed an app called Battery Doctor. It has a feature that will clear memory. I run that every so often. It seems to keep the iPhone from running so hot.
Battery Doctor also showed a strange app that I do not recognize. I don’t know if I should be concerned or not.
I recharge my iPhone regularly; but now I do not let it stay charging all of the time. Also, I often have it sit on an icepack just to stay cool while charging. Maybe I need an iPhone cover that comes with mini refrigerator?
I have explored online for solutions; but I have not found one yet. Perhaps I need to reinstall everything? I hope to figure this out soon or I will need to upgrade sooner than I planned.
I backed up, wiped, and restored my iPhone to see if that would help.
This morning when I connect to At&T, I see the sync icon still active.
I think that the music still needs to sync. I connected my iPhone to my laptop and ran iTunes. I started syncing and the icon changes to two arrows chasing each other in a circle. It looks like a lot of my music cannot sync.
The sync icon stopped swirling for a while … and then started to do so again. There is an app trying to install. I can remove it from the iPhone screen; but not from iTunes. It is an app I used for language translation. The sync icon stops swirling after I delete the app icon.
I ran the Memory Boost feature in the Battery app . I saw the strange app with Chinese characters listed again. However, my iPhone does not seem to be running hot while Airplane mode is off and charging at the same time. I will continue to watch what my iPhone does.
