Android battery usage

For Android 1.6+ If your battery isn't lasting as long as you think it should (does it really ever?), there could be a rogue process or application sucking down more juice than it should. And keeping an eye on what's hitting the battery is pretty simple.

Just go to Settings>About phone>Battery use and you'll get an easy-to-read chart showing what's been going on since your phone was last plugged in. Chances are the display (as in the phone's screen) will be near the top of the list, so turning down the brightness might be one of the first things you try.

Quick tip: See what's using the battery


The battery life on my Droid has been as good as I could really expect it to be. I did have an issue though where my battery was showing significant drain due to the display. I did a little investigating and realized that the case I was keeping it in contained magnets. The magnets were keeping the display on because the phone thought it was docked. Lesson learned... ALWAYS use cases with snaps or velcro on the Droid!

Hrm... any idea on how to find this on the HTC Hero or other SenseUI phones? The Settings in it don't have the option to look at the Battery Use that I can find, which is a little disappointing.

I haven't had issues with battery use or it not lasting long enough, so it's definitely not a pressing issue, but it would be nice if it's possible to see it at a later date, if need be.

You will have to wait for a firmware update as the Hero is still on 1.5 (article was for 1.6). According to Sprint, H1 2010 will give us 2.0 (or maybe 2.1, I forgot)

Install spare parts from the market (or it may be in your ROM if you're not running stock). It gives this option to 1.1 and 1.5 users.

quick tip? useful MAYBE 3 months ago, now it's just a waste of my time to even read this in hopes of seeing some new info

Quick tip - calling yourself "Fail", while it may be accurate, probably isn't what you're looking for.

You need to relax a guess is that you wouldn't have done anything earth-shattering with the ten seconds it took you to read this post.

Hey chris, this is for 1.6+ only the hero has 1.5 download spare parts from the market, it has the same ability.

I'd like some way to put a shortcut to that on the desktop. I use it all the time, and It's kind of a pain to get to. Maybe there's an app for that? ;)

Not sure what phone you are using, but on the droid you can create a shortcut to the battery use icon. You do a long press and then select shortcuts>settings>battery use.

I think it's a little late for this tip... This is something that should have been released not long after the phone. I found it through discovery, and I'm sure I am not the only one.
