Lots and lots of iPhone 4S owners complaining of short battery life. Charles Arthur had a run down of some of the theories and reported the experience of one reader:
"I then got a call from a senior [Apple] engineer who said he had read my post and was 'reaching out' to users for data and admitted this was an issue (and that they aren't close to finding a fix!) and asked lots of questions about my usage and then asked if he could install the file below and that he would call back the day after to retrieve the info. I extracted the file from my Mac after a sync and emailed it to him. He was incredibly helpful and apologetic in the typical Apple way!"

Then, on Saturday, Gizmodo offered further details and theories, along with a poll of readers. So far more than 14,000 people have participated and more than half (54%) said they were getting five hours or less of battery life. Yipes.
Arthur also has a bit more follow up:
A flaw in Apple's location services system in its new iOS 5 software is increasingly suspected of being the cause of rapid battery drain for some owners of the iPhone 4S.
