Kirk,
You didn't have much cell data, but you could have had lots of wifi data.
Perhaps, but not from actions on my part. If WiFi usage is the case, then it's something in the background.
Perhaps an app with push notifications, perhaps push email.
Not email. I'm completely on manual with email. Could be something else: Just go through each of the applications in the Notification center to see if there is a "push" flag set?
System activity monitor is a paid app that shows your CPU usage percentage - it should be about 2-4% normally. High CPU usage kills your battery.
I'll try to find this in the app store. Actual name is "System Activity Monitor"?
Also I notice you have a very bad cell signal. That may be part of the problem - the radio boosts its power if the cell signal *****.
Good point... but in my experience the older models automatically ignored the cell data path when a WiFi signal was available. Perhaps the 6.x.x iOS missed that?
Hard reboot (both buttons down until apple appears) You can combine this one with the next one.
Already performed this... dozens of times, but can combine with your next steps.
Go to airplane mode, then turn wifi on. This will eliminate the bad cell signal as a problem if it still persists.
As a troublshooting step, sure. Will Airplane allow the use of WiFi? If not, then will have to isolate the WiFi as a culprit too in some way. However, for a long term cure, can't just put the phone in Airplane... need to be able to get calls.
Change all mail to manual
Already done.
Turn off notifications in a binary search manner - this means turn half the apps off, if it persists turn them back on and turn half of the others off, etc. You need to keep careful track. When the problem goes away the last group turned off has the problem app.
Understand the approach, but the specifics need some clarification. By "turn off notifications", do you mean go into Settings / Notifications / In Notification Center and turn half of the apps off? Or do you mean another Settings page?
Minimize location services apps and see if the little arrow thing appears (means something is using it)
Generally, I don't see a location service icon at the top of the phone. But for the troubleshooting step, do you mean go to Settings / Privacy / Location Services and turn the "Location Services" switch off?
Troubleshooting like this is difficult and takes patience and time. But I believe you will find your answer.
I'm a badger when it comes to troubleshooting systems (just not an expert at iOS), so I can approach this systematically.
THanks for all the suggestions. Appreciate it.
