Hi all,
I was just wondering what everyone's else's battery usage looks like, because ever since I got the phone I've been having very poor battery time (it only lasts 7 hours with barely any heavy usage; wifi on only when needed). I want to know of it's something I'm doing wrong or if my battery is the problem.
I've disabled some annoying apps from running constantly (e.g. Photobucket) and am running Launcher pro with some widgets (manual refresh only). I don't know what else I can do to save my battery... screen brightness is low as well.
So, what does your Battery usage thingy look like and am I doing something wrong?
Thanks!
P.S. Is the 'Android' supposed to take up that much battery?

I get fairly good battery use throughout the day. I'd say with moderate to heavy use I get about 15-20 hours before the phone is dead. Right now after six hours unplugged it's at 76%.

Definitely look for juice defender, it saves battery life by turning off your data plan when the phone is on idle (screen is locked) and it automatically turns on when you unlock your phone. I had the exact same issue you're having now and only originally getting on avg 8 to 9 hours on my phone while I was only at school for 6 hours.
After a day of installing juice defender I can honestly say I can comfortably have my phone on for 10 to 12 hours of use with mild usage (1 hour of pandora, 1 to 2 hours of angry birds, and some web surfing) and the battery'll still be at roughly 50some odd %. Trust me you can definitely live wihout having your internet one when your phones in your pocket.. just my preference.

My phone seems to be getting pretty awful battery life lately. Over 9 hours (only 1 hour of which was screen on time), it's down to 22% battery. The phone has been sitting (screen off) for a good hour or so and when I picked it up, it's warm as if it's been awake. Android OS is showing a Keep Awake time of over 2 hours - twice the screen on time.
Following the advice here, I dumped my wakelock.csv file (which is actually a tsv but that's another thread).

But frankly I have no idea what I'm looking for or, more importantly, what to do about it. What is "main" and why does it have such an insane active since time [is that a unix timestamp?]? Why do wlan_wake, keyevents, and event1-226 have such high counts? I'm usually pretty good with this kind of stuff, but I'm at a bit of a loss with how to interpret this data :/
I also have the CPU undervolted (Gummy 0.3.0 with imo's kernel) and running at 350mhz most of the time. And frankly, the battery lasts about as long as you would expect if the phone were awake all day at 350mhz.
There's the problem, though. It's running at 350mhz most of the time.
Now, I should clarify this by saying that I just (as in, a few minutes ago) disabled Google Talk, Google+, and the "backup to google's servers" setting and already it seems to have made a huge difference, so I THINK I may have already found the problem. Before doing this, 350mhz far outweighed "Deep sleep."
Thanks to anyone who can help!
So perhaps my post was pre-emptive but disabling those three things seems to have solved this. It's cool to the touch while idling, and more importantly, the battery seems to be doing great now. It was losing about 10% an hour and now it's about 0.5%/hour while sleeping.
Again, I disabled:
-Google Talk
-Google+
-Google backup (In Settings > Backup & Recovery).
I don't know which (if any one thing) did it but it's DEFINITELY better.
What the heck killed my battery? This is with the extended battery and I started from a full charge after flashing a new rom and clearing battery stats..
I turned off all connections, and turned off sync.. Sat the phone down and went to bed after about an hour of web surfing.. I went to bed with 70% left and woke up 6 hours later with 37%...

Its all in the last screenshot. Keep awake time is huge. That's the bug if I had to guess.

That keep awake time is normal, nothing strange there...
Your story of browseing for an hour then going to sleep for 6 hours doesnt match your batteries' graph.
According to your story, there should have been a sharp decline from browsing web since the screen would be sucking the power, then a very slight decline from being idle, something was either running in the background (facebook maybe, it has a high % of usage) who knows?
Yeah idk.. If you look at when wifi was on that was when I was browsing.. Then after that there is a steep decline which doesn't make sense to me.. I don't think it was Facebook or anything because all data/sync was off...
I know it takes a day or two for a new rom to settle in but I certainly wouldn't think it would have that large of an impact

I read somewhere that there is/was a bug where after a reboot Google talk or maybe google+ launches the camera in the background which keeps running until you manually open the camera app and close it. I believe I read it some where on Franco's kernel post. Not sure if the bug is still there and if it's the culprit here, but might be worth investigating.
I picked up betterbatterstats as my battery life has been crappy over the past few days, I have found the following to be true: I am barely using the phone as I'm at work all day and the battery is draining much faster than before. My screen time is 20 minutes total for the following stats.

I'm not sure if I'm not using BetterBattery correctly but I can't find an option to tell me what offending processes are keeping the phone awake for so long. How do I figure out what is causing this?
Thanks for any help.
Check partial wakelocks in better battery stats.
Turn off your GPS. That is what worked for me. I have 9h 6m 20s on battery and Android OS only has 51m of awake time.
check your apps, if you're not using them, close them. ask yourself, what apps do i have installed that require wakelock permissions. those are the ones who will drive android os through the roof. latitude. maps. email. feeds. even games can trigger sensors and not let go of them properly, leaving your cpu always working. check cpuspy from market.
turn off autosync. you're working right? no point getting distracted over some lame ass post on fb or some worthless spam in your mailbox.
Ok, so now this is weird. I don't have any apps keeping the phone awake for very long, but the wake counts are retarded, take a look at the attachment. The time is very low, but the count is over 2k. The phone is at about a 75% wake time. This really doesn't make any sense.
Hey all,
I just thought I would post this as I thought it was quite incredible.
I don't know what HTC's stats are on 'standby time' (which is usually how long a phone will last with no radio gear active) but look at how long my Desire lasted when I took the sim card out

That's 302 hours
Just Sayin'...
Another thing that I noted was the vast amount of 'awake' time vs 'screen on' time, sometimes lasting hours.
What does android have to do so desperately whilst the screen, radio, wifi, in fact everything is turned off??

Its not Andeoid really. My best bet would be that Go Weather app.
via xda app
I'm not entirely convinced that it is, I could uninstall GoWeather or do a /userdata wipe and retry to see if it'll last any longer?
Even if you put it on airplane mode, the apps you have would still try to wake up every now and then to try and refresh themselves. If you have a resource hungry app then it will wake your device to do the task it needs to perform. It may or may not be go weather app but there is something installed on ur phone that is keeping it awake even on standby. That's what I think anyway.
via xda app
Ha ha ha ha...looks about the same as my desire. I got one hour battery life on idle once with 3G off, wifi off and most of my user apps killed.
My phones been charging for the last four hours and it hasn't moved from 75%. It dies in ten minutes If I use the data connection when it's discharging.
I got this tablet 3 days ago and battery life was horrible.,but now it's just amazing .I was curious what battery life other are getting post battery life screen shots below . Also is it normal for it to charge under 1 hour and 30 minutes on wall charger?

welll, after the lollipop update, my battery went strong lol, in kitkat, normal browsing/youtube at 1/8 brightness will drain the bat like 50% in 2 hours. playing COC drains as much as 1% a minute and the batt percentage jumps, the device will get so hot to a point that it will induce a warning and will close all apps,. it will deplete the batt so fast that it shuts off. showing 1%, powering it on again will show at least 30-40% juice left. in lollipop, since like the batt meter is now calibrated and playing COC will no longer make it hot.
Kitkat last me half a day with casual browse/sms/calls
lollipop lasts me a whole day and i still have a bit juice left
2 hours is a bit fast, was it a full charge, the 8,4" has an 4900mah battery and the charge puts about 1500ma into the battery in one hour, using supplied charger and cable, other brands can cause your tablet to charge much slower.
try the free version of GSam Battery monitor, it`s one of the best to keep an eye on your battery.
