Better battery life for Android system?

I've seen a lot of users' postings of battery statistics (screen shots) and they are all considerably better than what I am getting. The biggest difference I see is in the amount of battery drain from "Android System." What I see posted is between 9% and 13%. However, my batt stats show the Android System draining 60% of the battery.

So, what am I doing wrong? I'm still kind of new to Android. Is it the widgets? I've checked running processes verses what apps are draining battery life and nothing is running that drains like the system does.

Further info: I am currently running the 7.18.12 build of Diet ICS, but I was seeing this behavior on stock as well. Some widgets I use: Astrid premium tasks widget, Evernote, doubletwist, slacker, 3D clock/weather, a widgetsoid switcher, and APW Calendar.

Thanks for any help or suggestions.

How much screen on time over how long and what kind of use?
60% is high but there's known bugs in android OS reporting.
I'm asking because you we're saying your new. It takes a lot of power to power this 4.8 screen

How often do your widgets that gather info refresh? Try scaling down on some widgets and see if that helps. If not, try to flash stock with odin and start over. I was having some problems with my phone when I first got it (MTP specifically) and I falshed stock and everything started working fine. Also, if you are using Google Chrome, make sure you have the experimental feature of using the gyroscope for tilt scrolling set to off....it is known to drain battery.

Hope this helps

Maybe I will try flashing stock if I have time today. I reset my battery stats in recovery mode when I took the phone off the charger this morning, so we'll see how today goes.

I looked into the widgets and the only one that refreshes data on a schedule is the clock/weather. I'll try a different one or just not use the weather.

Great tip about Chrome. Didn't know it did that.

Do I actually need to calibrate the battery? I tried the method of letting it die and charge back up a few times and I've tried recharging once it gets down between 70-80 percents life. I'm not sure which method helped, but I did notice an improvement.

Thanks again for the help.

Not sure how to know how long the screen was on. Is there a way to know that? If I had to guess I'd say 4 hours. I use the Smart Stay option as well. I wonder if wiping the stats will give me more valid data.

Thank you for the help.

I have my display off auto-brightness and on a low setting, I probably utilize the task manager 50x a day and clear the ram as well, cpu sleeper is always activated, gps/sync/auto-rotate/wifi/bluetooth is always off unless I need them, and I have power saving mode on most of the time.

With all these settings off and I am a heavy texter/caller/browser/emailer, my battery lasts from 7AM-1AM and I am at 30-40% at the end of the day!

Great advice. Thanks. What do you use for "cpu sleeper"?

Never mind! Just searched" CPU sleeper" on the Play store and--voila!


On another note, I'm so glad I got a device with a huge support community. Coming from iOS, it's nice to feel part of a collective effort again and get such great advice. I know there are a lot of iOS forums and there is some great work done through those communities, but those seem so trivial compared to what is done through XDA and the level of helpfulness is unparalleled here.
