I got the Android 2.1 operating system onto my HTC Hero yesterda. I noticed that if you go into the battery status page (Settings>About Phone>Battery), it no longer gives me the percentage of time the phones is awake or asleep. I realize it's not a hard thing to compute but it's somehwat inconvenient if you're trying to figure out the optimal settings to extend battery life. Has anyone else noticed this or is it just a problem with my phone?
It does give you the Up Time and Awake Time (the Awake time has decreased significantly for me) and you can also click on Battery Use and it gives you a list of what is using the battery and percentage. I do know there are apps in the Market that will give you more information but I don't like to use more battery than is necessary. Good luck, I have found limited issues with the 2.1 upgrade and improvement in Battery life, etc.
