iPhone Battery Drain, revisited

It happened again. I earlier blogged about the situation where my iPhone started eating the battery so fast that it was actually hot to the touch. Again, the issue was near-continuous network access to my home Exchange server (over ActiveSync), but this time I was able to resolve the issue by disabling calendar sync (which deleted all the calendar entries for that connection) instead of deleting the whole profile.
As soon as the calendar stopped being sync'd, the high network utilization went away; re-enabling the sync brought back the calendar items without causing the utilization problem.


  1. Wow, I've never had this problem. I've noticed that my iPhone gets really hot now when I charge it but I haven't started losing battery life.

    1. I've had it happen so many times, now, that I don't even blog about it anymore. I simply kill the sync on all my calendar connections (I have 3 that I keep active), then restart them a bit later.
