Came from a Galaxy S2 thinking I'd almost be doubling my battery life, but the battery life on my brand new Note 2 seems significantly lower than expected based on reports here. Getting battery lasting 18 hours or so including about 3 to 4 hours screen on time, which frankly is about the same as my Galaxy S2.
Here's some things I've tried:
* It's been used and recharged a few days now, so it's not just that the battery hasn't been "broken in".
* Google Chrome uses a lot of CPU time. It was using more CPU time than any other app, and in battery usage terms almost as much energy as the screen. The stock browser uses much less CPU time for about the same amount of browsing. I have stopped using Chrome and signed out of my Google account in it, disabling all Chrome-related sync tasks. No one feature of Chrome seemed to be the culprit. It wasn't the "tilt scrolling" that was a problem as I had that turned off.
* GSam Battery Monitor is a great app to measure how much battery applications are using, and it proved valuable in singling out Google Chrome as a culprit.
* Nonetheless, I still am down from 100% to 60% battery with only 1hr 20mins screen-on time so far since last charge.
* High CPU time usage is coming from "Kernel (Android OS)", then "Internet", then "Android System", then everything else below that is negligible (Facebook, Twitter and Google Keyboard rate at about 2% each but that's fair because I have been using them). Phone and Phone radio battery usage is negligible (even though I've made phone calls). App usage is using nearly as much as screen.
Any more tips?
