As you all know, Apple has released iPhone OS 3.1 few days ago. However, in the release note, it doesn’t mention any bug fix or improvement about the battery life. Despite of this, I’d like to check with you:
Is the battery life improved on iPhone 3.1? For me, it seems like a little bit better. I haven’t performed any serious test on it. It’s just my first impression after the upgrade. So, how about you?
