Comment 73 for bug 527458

As a result of the tooltip removal there is now one piece of information I cannot find anywhere: the current battery charge while I am on AC. If I click on the battery indicator it tells me how long I have left to charge until the battery is full, but it does not tell me how long I would have left if I unplugged the machine now. This is often useful information when I am considering whether I can take my laptop off AC and carry it around the flat, or whether I need to leave it on charge for when I go out later in the day.

Yes, I can get this information by using a command-line script (such as the one I used to use to power an OSD battery indicator before I switched to the GNOME desktop), but really...this is a classic case of Ubuntu removing perfectly working functionality without having a replacement. (In this case, the obvious replacement would be to add the information to the menu, but I agree with many commenters above that having to click on an indicator to get frequently required information sucks).
