Apple has begun investigating claims the new iPhone 3.1 firmware update is significantly reducing battery life.
A number of disgruntled users have been posting furiously over on the Apple Support forum, with nearly all stating that the new upgrade has led to a significant reduction in battery life.
According to The iPhone Blog, Apple has sent emails to a number of those concerned, asking a number of questions about their experiences.
One of the more interesting posed is: "When you notice a power drop, does it seem to be a legitimate power drop, or rather an issue with the battery icon indicator?"
Apple is asking the users to install a battery life logging application on the iPhone, which measures the power drop rate and then sends the data back to HQ when synchronised with iTunes.
