An app itself doesn't use much battery unless it's doing something CPU intensive. Android reports the actual thing that was using the battery. For example, if I watch YouTube until my battery's dead, it won't say YouTube used the battery, it will say the screen did.

Isn't that what he said?

  He's saying he doesn't think Google Now uses much power because it doesn't shown up in the battery statistics, but he also says that GPS shows high usage. I was saying that Android doesn't report an app's usage of GPS etc. as battery usage of that app.

    Does Google Now even use GPS? Passive wifi/cell tower location will probably work for almost every feature I can recall.

That is not actually true, because YouTube is quite CPU intensive. If you perform the experiment you just proposed, you will find YouTube has used a significant portion of the battery. But I see what you mean. You could also try this: if Google Now is waking your phone up any significant portion of the time, it'll show up in the list as a low percentage app. You can click on it to see how much time it's keeping the CPU awake, keeping the screen on, using the GPS, etc. I believe Google Now processing is accounted to the Google Search app (because that is where all its output shows up). On my phone, which has Google Now enabled, it shows zero active time for GPS, screen awake, CPU, etc.

  Actually, Now's time goes under Maps- at least the location services, which are the big draw. I have all of the tracking enabled, and maps uses between 20 and 30% of my overall.

    Oh, in that case, yeah, it is using a fair amount for me too -- don't get me wrong, I'm still at 85% after charging it this morning, but maps is showing about 30% of that.

      Lucky :) Even if I don't use my phone at all, it'll be below 80% by this time, and Maps & co seem to be a major culprit, since Now keeps on chugging even when the phone hasn't woken in a long time. Interestingly, GSam battery monitor (which I just got last week, and is really neat!) shows the number of times each app woke the device. I've been on for 4.5 hours, and Maps is at 441, with the next Android System at 85 and Google Search (which is Now) at 53. Android System has also shown up more in usage % since I started having Now. I think there's definitely a significant drain with Now. I've had it enabled since the Verizon release, somewhere around 12/20, but I think I will disable it at the start of next month and keep an eye on how it behaves. I certainly feel that my battery life has gone down since the upgrade.
