The other day, I had a 56% "Android System" battery usage. Is this too much? Or is this normal?
Don't you mean CPU usage instead?
Currently I have 72% and all is working just fine.
As long as your phone is not slow or unresponsive, I think you shouldn't worry
Should be fine. It really depends on what you do with your phone. All that means is that out off all your battery usage, 56% was from that process. It doesn't mean it ate 56% of your battery, just 56%, of the total usage time.

I'm on here often and see of screen shots of peoples battery info. I don't see any one as high as mine. Here are my battery stats being unplugged for 6 hours and 1m
Display 74%
Cell stand by 7%
Phone idle 5%
Android system 5%
Dolphin hd browser 4%
Voice calls 2%
Swype 2%
I haven't used it much this morning so maybe the screen is taking up the most, but it always is the highest percent. Any ideas?

Are you running CM6?
Yes, is there an issue with this also?
Been unplugged for 2h 58m
My top is Cell Standby at 25%
Bottom is Display at 6%
rooted/forever/2.1/Hydra uv stock clock
I have auto-adjust off and keep the screen fairly dim, simply because that's how I like it not to save battery.

Im not sure if it is an issue but CM6 will show high display usage, where else other ROMs would usually show cell standby higher.
High display usage is a common theme on every single phone...it's what takes up the most battery in devices. Turn down your brightness if it's getting to be too much for you. Keep in mind that charge is the percentages of the battery taken up so far. so 75% of battery if you only have 10% gone is only 7.5% of your total battery.
Hello everyone
I got my DHD last week on tuesday, very happy with it so far!
So I was playing Slice It for about an hour and a half, and my battery went from 100% to 56%.
Battery Use shows this:
1h 36m since unplugged
Display 58%
Slice It 29%
akmd 5%
Android System 4%
Cell Standby 2%
Mediaserver 2%
Wi-Fi was off the whole time, brightness was at about 15-20%, and the volume at about 35%...
Is this normal for the battery to run out so quickly?
P.S. I did charge the battery for 8 hours before any use like the manual said.
Cheers
Yeah its normal for a less than 2 week old battery. My battery got progressively better every week up until week 5 or so.
Your battery will get better. Plus you were using your phone quite heavily so everything sounds about normal.
The battery doesn't last too long on the DHD. I've noted marked improvements by using a combination of JuiceDefender and AdvancedTaskKiller minimising bg apps.
I've been better monitoring my batterylife today to see if I can get by on a normal work day or if I'll need an exteded battery (ever since getting the phone its been dying very quickly, because I've been playing games on it). So far, it's been going all day and will definetly reach the 10 hour mark with web browsing and texting. However I do 1 concern, 30% of my battery life has been used up by 'Cell Standby'. Is this normal? I had an extended battery on my g1, so I never had to worry about battery life too much, and don't know how much cell standby took up on it. I'm just suprised that it takes up more than "android System" or anything else on my phone.

(Could it be because its on the att network?)
Update- just to give you a grasp of my battery usage for the day:
was not put in charger all day
currently at 10%
been on for 13h and 56m

cell stanby 31%
Phone Idle 22%
wifi 19%
display 13%

My phone seems to be using 2% battery every 15 minutes on standby, worse when its on.
When I check what is running, it says Android OS 50%...... what can I do? I usually charge my phone three times a day.

I use a variety of apps to check what is going on with my phone.
Watchdog - monitors apps for excessive cpu usage
Cpu spy - see how long your phone stays at each frequency, but more importantly in deep sleep.
Battery monitor widget - monitors battery usage
System tuner pro - get detailed analysis of a recorded system usage.
Also, when in battery usage, I click android os to see how long it has kept your phone awake. Have you made any changes to your phone? Installed a custom ROM?

Also...give it a few days of charge-ups. It really does make a difference.
FWIW, with moderate use, my Droid Charge 4G does about 10-15% every hour. So I don't even think 8%/hr is that bad... :/
no changes to the phone, its all stock. Any benefits moving to a custom ROM on the nexus?
I've had the phone for two weeks, battery has deteriorated. Now charge it three times a day.

You probably never calibrated it properly to begin with. Charge to 100% > unplug > wipe batterystats.bin > let the battery drain completely until the phone powers off. Then charge it continuously over night and in the morning unplug and let the phone drain completely until it powers off.
I am a pretty heavy user as I text literally every 2 minutes all day (girlfriend ) and I manage to get 20-25 hours easily.
I also drain my battery out completely every day for good measure
Charging in between screws up your calibration, try not to charge unless you are below 15%. And do not disconnect it until it is fully charged (98-100%).
Note: I've also noticed wifi saves you a lot more battery juice than being on 3G/4G, so keep your wifi active if you are in range

This is just not accurate for Lithium Ion batteries, which have no cell memory and gain more from frequent shallow charges than deep charges.

Not to mention draining a Li-ion past 5% can shorten the life of the battery.
Further Li-ion's have a lifespan measured in cycles. You get about 500 cycles on a typical Li-ion. A cycle is a drain and charge. If you use 50% of the charge and then recharge to 100% you only use half a cycle. By needlessly draining the battery you are using up limited cycles reducing the life span of the battery.
While I'm sure android's calibration needs to know the upper and lower boundaries of a charge I'm certain it would be smart enough to handle charges when the battery isn't completely drained. Most battery calibrations work this way. Every once in a while you need to charge to 100% drain to 5% and recharge without using to 100%

Clockwork Recovery -> Advanced.
.. file is in /data/system i believe
its probably a bad app working with ICS.
Use watchdog and it will tell you.
Check your widgets that they aren't constantly refreshing.
My Nexus is currently at 50% battery life. Of the 50% that went by, the two highest contributers are screen on (50%) and phone idle (20%). All this time, the phone has been on airplane more (with wifi). Why is phone idle so high?

Could be an app/process waking the phone. For more advanced battery usage troubleshooting, try an app like BetterBatteryStats.

Could very well be this! I installed Google Wallet yesterday and I did notice some drain from this app. Better battery stats tells me it's contributed to 2 hours! I'm going to force close and wipe the apps data.

Phone idle is so high because your phone hasn't otherwise used any power. Even just sitting around is going to use some juice, hence the high percentage attributed to idle. Since you haven't really used it, other processes shouldn't have consumed as much.
Look at it in perspective. Your battery stats are going to tally up to 100%, or reasonably close. If absolutely nothing else at all consumed any power whatsoever, phone idle would show 100%.

Exactly this!
If you feel that the phone gets more battery life, you shouldn't worry. It's normal.
If you feel that the phone consumes more battery (Hence lower battery life), then check betterbatterystat or CPUspy, just in case it the phone isn't getting those deep sleeps.
