Develop Bugs

What sort of battery performance are people seeing?

So I've had my Defy a week and I like it, more than I thought I would to be honest.
However, one thing that's bugging me is the battery life.
In their review, Engadget actually highlighted the battery life as one of the big plus-points of the Defy.
They state:
Engadget said:
In our experience, the Defy seems to have stellar battery life, which is relatively hard to come by among Android phones. Not only we were able to consistently make it comfortably through an entire day on a charge, but we were surprised to find that after putting the phone away with about 75 percent charge, it was still on with 21 percent remaining two days later. Granted, it spent most of that time in WiFi calling range (which disables the cellular radio), but many smartphones give up the ghost from 100 percent charge in less time...

Now, I'm not using wi-fi calling but I don't think that should excuse or explain the fact that my phone barely lasts a day when at least one other handset has such significantly better battery life.
Anyway, I was just wondering how everyone else's Defys were performing.

Im coming from a vibrant and the battery on this is the best on android so far that i've ever used(g1, mytouch, mytouch 4, vibrant, etc.

If you don't mind me asking though, how long do you go between charges?
As I said, I'm lucky if I make it much more than a day - certainly two days isn't possible.
But I'm not a particularly heavy user, a bit of internet and a few texts here and there but very little in the way of calls, so I kind of feel like I should be getting more out of the handset.
When I check the battery usage, it's quite often ~40% each for 'Mobile Standby' and 'Phone Idle'.
So the vast majority of the drain is just from the phone being on, not from anything I'm actively doing.

Is this your first smartphone? =)
I go a day and a half or so. I'm heavy on web use and playing 'slice it' all day.
for my usage, im THRILLED to have a phone that can still have 30-40% at the end of a long day.

Just try to reboot the phone after fully charged and detached from power. There is an issue with the "suspend" process in some cases (not only on Froyo 2.2) which disappears after rebooting. Mine lasts 2-3 days with average use.
The issue at Google (I am not allowed to post links as a new user )
code.google.com/p/android/issues/detail?id=11126

I can use the web steady for 5 hours, this includes some streaming video, if I start at 100% its down to 10% by then. At work it lasts easily all day but it gets little web usage and maybe an hour of talking. I use battery booster and advanced task killer, my backlight is set at 70%.

With moderate use (some calls, lots of texts, some web browsing) I get 2 days. It needs to be charged at the end of day 2, but I'm happy with it. I don't have any ot the social networking crap on so it's not constantly syncing. I think that may have something to do with it. I keep my backlight way down too.

Battery life? i got defy just a week ago and first impressions are good. You know, in the first days you make yuor phone working a lot, testing all the features, trying new apps from the market (so internet connection always on) , watching some movies, playing 3d games!
So a really heavy use, but power lasts at least 1,5 days. So i think using the phone moderately makes the battery life easily up to 3 days.
Try some task-killer app, and then test the power duration. Some softwares stay in background and keep draining power.

No.
And I don't see what that's got to do with anything.
My battery life seems to be noticeably poorer than what the majority of people here are quoting.
If I were to use the web for 5 hours, there's no way I'd have anywhere near 30-40% of my battery left.

Having looked at your link, it sounds as though when that's happening, people can see the Suspend process listed in the break-down of what's using the battery.
I've never seen it listed, so I'm not sure that's the problem here.

I've got Spare Parts installed and it's set to 'aggressively' monitor and kill processes.
A friend recommended it over the likes of Advanced Task Killer because it's supposed to be better at differentiating between apps that are safe to kill and parts of the core software/system that could cause issues if closed.
I get what you're saying about using the phone more than normal because it's new but in the 8 days since I got it, I've spent 7 at work, so I haven't had that much scope to mess around with it.
I've switched the screen from automatic brightness control and I've disabled the background syncing for facebook, so hopefully that'll make a difference.
If not, since it's just over a week, I'm well inside the 28 days I can have it swapped for being faulty.

Quadrant: 1100 points, Linpack: 6,49 Mflops
Edit: ooops, should read the title more carefully next time.
My defy runs for about 40 hours on one battery charge.

i have to charge mine everyday at night after using it whole day, time to time. Not bad tbh.

A task killer is NOT necessary.
It seems like blur services are push rather than pull which uses much less battery (think blackberry). But im not 100%.
I've set up yahoo, corporate, facebook, and picasa just to test it out and it didn't make much difference in my battery life.
I consistently get a day and a half (unless i play games). Can push to 2 days if i put on airplane mode overnight.

Found this on a german forum, as you can see, he was not in flight mode. I guess my desire's battery won't last that long.

I can go about one full day with moderate/somewhat heavy usage. Won't last 2 full days though.

People keep saying that but I'm not convinced.
I mean, if I use my browser say and then finish using it and know I won't need it again for a while, why prevent me from actually closing/killing it?
It seems so ridiculously counter-intuitive.
Plus, if it's really not necessary, then why are so many of them being developed?
Even Samsung are producing task managers now for devices like the Galaxy Tab - if it really wasn't necessary, surely one of Google's top hardware partners would know that.

And samsung is so great at making stuff...? Touchwiz??
Also, samsung's task killer does not show inactive or background apps like most task killers do.
What is the harm in the browser being open? It uses no cpu+ this phone has more than enough ram that it doesn't need you to close apps to keep things running smoothly.
It also will not improve your battery if you arbitrarily close an app only to re-open it later and use more processes.
Just my 2 cents on this topic.

Something i already posted in a german forum about my battery life:
2,5h gaming (Zenonia),
3h mobile internet (ICQ, Yahoo-mail, web, market)
2h of activated WLAN and deactivated sleep to copy stuff from pc to Defy
1,5h music (radio)
and 1h (and 6 minutes lol) of phone calls
After that day, i still had 30% of battery.
The maximum i reached were 75 hours including MY normal use with some mobile internet, some texting and 1 or 2 calls...maybe an hour of gaming at most.
I did not charge it first when i got it, because the battery was at 80% already/still and i wanted to play around.
Current running time: 26 hours...i activate plane-mode at night from now on. Low 70s now.
Everything at minimum display brightness (30%?)

In my opinion, a task killer is absolutely necessary.
All the apps launched keep consuming RAM even if they're not in use. I brought back 106 mb last time i performed a task killing! In most of the cases less ram means worst performances / more work for cpu.

[Q] Terrible battery no matter what... anyone else?

I've had 3 or 4 different evo's and it's been almost impossible to receive decent battery life on almost any rom. It started with CM6 and I switched even though I loved it and went to Baked Snack or some other rom that stated battery life, but it just always ends up dropping on me no matter what. I thought my expectations were too high, I just recently got my last replacement and it's now 3-4 days old. I heard how CM7 and Miui's latest had excellent battery life so I couldn't wait to test them. I first tried CM7 and as long as it's on stand by or not being used the battery was pretty decent I guess. That's with Green Power free running btw. when I turn the phone on to start using it, the percentages just drop. Tried Miui after hearing how good the new battery life is and almost the same thing.
So, that led me to believe it was due to some program, but for the most part I keep these stock. One of the first things I setup are a Gmail account, FB account setup... then of course my apps are added automatically hardly any widgets ever run. If anything it's Buzzbox, I've got beautiful widget's clock now. I use Vlingo, not sure if it's a hog. When I check the battery stats, there's nothing crazy or out of the ordinary. Anyways... there's got to be something wrong, I'm guessing. I've got a regular battery and an extended battery and they both do terrible. I'm going to install a rom from scractch with nothing loaded at all and test the battery. I hate to do that, because testing will take awhile especially with adding one program/widget at a time to monitor the percentages lost.
Here's a list of apps I normally have on my evo and run occassionally:
Vlingo
Green Power Free
Juice Defender (before green power and GB)
handcent
buzzbox
facebook
Swype
Google Services
Voicemail
Are any of these battery abusers without me knowing it?
I normally keep wifi on and connect to it over the 3g data, although I believe Green Power said it cant control the data on the GB roms as of now.
Today, I started with 98% with my extended battery, CM7 and now at 1:00PM I'm at 70% Minimal usage.
Sorry for the long post.
Bluetooth is off most time and Wifi like I mentioned usually is on, because I heard it uses less power than mobile.
sorry for the long post.
Just looking for some assistance.

Restore it to stock.
Calibrate your battery.
Use it for a few days without installing all your apps. If the battery still sucks, then you are probably going places that do not have signal and the phone is searching a lot. Check About - Battery for time without signal.

get a seidio 3500 mah battery and you will enjoy your phone with every little feature turned up to the max

It is a Seidio
Of course it's not as bad as the original, but watching the batter go down 10% while I'm using it is very disheartening. Awhile back, I was able to get decent battery life, but I can't remember what rom, it might have been Baked Snack like 1.6 lol, guessing anyway.

Nuggyunlimited looks like he is onto something. I do not know if he has 4G or not?
I have had my best luck with mikFroyo.
What is going on with google maps? I have the same problem wiht MikFroyo

I am one of the heaviest users around, I stream pandora for about 8 hours , listen to music app about 2 to 3, check facebook and certain websites constantly, my two email acounts check every five minutes, my brightness is at 100 percent, my gps and location services are on, I'm overclocked...using 4.3 mikfroyo with sbc number 7...at the moment I'm using miui with sbc 7 for aosp roms, depends what you do, but either way no matter what kernal or rom you use I'll tell you, this battery will last you all day, this battery changed my evo experience...
edit: I don't use setcpu for profiles, just for overclocking, i dont use juice defender, the useless task killer or anything
edit 2: Conductive i had the same problem update to 4.4 or 4.3

so let me get this straight, average use is 8 hours of pandora, 8 hours of sleep, and that leaves 8 hours for facebook and etc, so lets say 4 hours total for a guesstimate, leaving 4 hours of non activity of the phone being off. 20/24 hours is "average use". I mean this is not a competition of who uses theyre phone more, all im saying is that with this battery you can do pretty much whatever you want without caring with ANY rom or ANY kernal you want.

No I use my bluetooth headphones for music from around 8am-6pm entire time I leave the house to the time I get home. Both facebook accounts every 15 minutes same with both.twitter accounts on xda off and on all day I.text a lot and use g talk a lot with a few calls I wasnt posting it as a battle I was actually just saying we get about the same times but I use the phone a little more and I was agreeing with you that the battery works wonders

i just got my evo after a hero.
the battery life is exactly what i expected. ive got a stock sense, rooted with clockwork.
i dont use widgets, no auto syncs. i have complete control over my device and it never leaves my hand. that being typed, i can get about 13 hours of up time.
yes, id like the battery to last longer but im not willing to have a fatty evo for the 3500mAh battery. I purchased a second stock battery, official HTC, so if Im gonna have a long day, ill have a battery with me.

Ok, yesterday I loaded Miui with nothing additional except changing the LCD density to 200, green power (which is useless since wifi doesn't work with this kernel) and right now I'm at 14h, 49m since unplugged with 17% left (normal battery). That's with minimal to average use. I notice when I'm using it, I can watch the percentages just drop, so I guess it's functioning normally and it's due to just my usage and programs, I'm probably expecting too much from my battery, once again I guess. I'm going to try your rom next with my extended battery.

I know what stock battery users go through, and with heavy use they don’t last too long, but I’m now in a different, horrible place entirely and I have the 3500 mAh battery!
I know that something is clearly wrong with my Evo but no one seems to know what it is. As I said I’m also using a 3500 mAh battery, but not to any advantage. In fact I get considerably less usage with this now then I used to get with the stock 1500mAh battery, regardless of the ROM or kernel.
Current specs:
HTC EVO 4G, Hardware 0003
16GB Wintec Class10 MicroSD
SEIDIO 3500mAH Battery/Camera Protector
Calkulin's EViO 2 v1.7.7 (have run several different Sense and CM ROMs)
HTC kernel #15v7 (doesn’t matter, have tried stock and every TM, regular and SBC)
Quadrant ≈ 1365
Linpack ≈ 33.05 MFLOP
and…(drum-roll please)
Battery Life: 70% after 6 hours, literally next to no usage.
Before middle of last November, if I charged the phone fully (without the benefits of SBC), and then just unplugged it on a Saturday night and let it sit unused for like 19-hours, the charge would be around 89%, +/- 1%, with the stock battery. In that same scenario now the 3500 mAh battery would have shut the phone down long before 19-hours rolled around.
Yesterday, using the 3500 mAh extended battery, no phone calls, Bluetooth on for about 20-miutes this morning for the drive to work and was turned off upon my arrival, and I’ve sent and received 4-5 messages on GTalk. That’s it.
The current status:
Charge: 70%
5h 52min unplugged
Up time: 6:15
Awake time: 1:20
Battery Usage screen:
Cell Standby: 42%
Phone Idle: 43%
Android System: 8%
Bluetooth: 4%
Display: 3%
Phone runs great; everything works great, no other issues. It once fell about 10”-12” onto plush carpet (kitten attack). It was in the Sprint case with the stock battery then, and has not been dropped otherwise. If anything, I am ridiculously careful with it.
Something happened the middle of last November like a switch was flipped, and battery life has been horrible ever since. Since we got our Evos back in the very beginning of June, 2010, I don’t think that returning it to the Sprint Store was an option then or now.
No one seems to have seen anything like this or have any clue what the issue might be, but it was suggested that I RRU it back to original, update it to current and then test the battery usage. Then, basically just live with it and see if it helped. After that, I’ll re-root and get on with life, whether battery life is better or not.
Any constructive thoughts are welcome. Thank you for your time.
Note: my apologies is this constitues a thread hijacking; not my intention, just saw title of the thread and it sounds like my life.

Thank you for the input. I thought about that so I tried the 3500 mAh in my wife's stock Evo and it runs forever. I'm so envious! I've swapped her stock battery and mine and they both run the same in either phone.
In mine, the stock battery usage is proportional, too. Fully charged and unplugged at 6:00 AM and with absolutely zero usage, sleeping screen off the entire time, by around 2:00 PM the stock battery was at 41%. That was also with very minimal synching (I've tweaked those settings nicely), no bluetooth, etc. I believe that the awake time was like 36mins. Sick, but unfortunately not in a good way.
Since it can't hurt, I think that I may do the RUU thing this weekend and then re-root afterwards. It may not help, but its literally the only thing that I can think of that I haven't tried.
Again, thanks for your thoughts. Have a great day!

Sorry, I've bypassed your rom for so long, but I've got it loaded now. Looking forward to trying it out. I can't lie I love and miss CM7 and Miui, but if my battery seems to last longer with a sense rom, then I'll be switching. So far it is very snappy and quick. Do you recommend I stick with the stock kernel or switch to something else? Do you use any setcpu, juice defender, green power or anything?
Do you have theme's as well?
Updating a titanium backup for my apps now.
I'll post back how it goes. I would say I had the same problem as the user above, but this has happened on mutliple phones and roms.
I know with a new phone you need to cycle the battery quite a few times. Someone told me roms were similar, even though I never understood why. Would you say that's true? In order to give the rom time to adjust to the battery and settings you need to give it 3-5 days?

[Q] Battery life/kernel question

I am currently using CM7 RC4 and have been reading through the CM forum for tips on how to improve my battery life. I must admit that I have tried various kernels (CFS and BFS as well as SBC and non) but nothing seems to really make a difference.
I average about 6 to 8 hours of battery life with light to moderate use. The most time I spend really using the phone is for the 2+ hours when I go to the gym and use Pandora. Besides that, I send some texts, browse the web and use Facebook. I know that there are a lot of variables when it comes to interpretation over how much use of a phone is "a lot" but still.........I hate how quickly my battery drains.
In one instance, I went to bed at 1 a.m. with 99% charge (having been off the charger only 30 minutes) and when I woke up at 8:30, I was already down to 57% with high Cell Standby as well as Android System.
I have now gone through and done the change on my phone to set the radio to "CDMA Only" as well as disabling Auto Sync.
I am currently using SavageZen Kernel CFS 0.2.1 and will report back on how it does overnight but.....definitely not holding my breath.

I am currently using CM7 RC4 and have been reading through the CM forum for tips on how to improve my battery life. I must admit that I have tried various kernels (CFS and BFS as well as SBC and non) but nothing seems to really make a difference.
I average about 6 to 8 hours of battery life with light to moderate use. The most time I spend really using the phone is for the 2+ hours when I go to the gym and use Pandora. Besides that, I send some texts, browse the web and use Facebook. I know that there are a lot of variables when it comes to interpretation over how much use of a phone is "a lot" but still.........I hate how quickly my battery drains.
In one instance, I went to bed at 1 a.m. with 99% charge (having been off the charger only 30 minutes) and when I woke up at 8:30, I was already down to 57% with high Cell Standby as well as Android System.
I have now gone through and done the change on my phone to set the radio to "CDMA Only" as well as disabling Auto Sync.
I am currently using SavageZen Kernel CFS 0.2.1 and will report back on how it does overnight but.....definitely not holding my breath.
Any helpful tips are appreciated.

First, make sure you've done this: http://forum.xda-developers.com/showthread.php?t=712990
Also, turn off your back up data to Google servers in settings > privacy.
I've had it off for a good 5 hours or so and my battery life has already drastically improved.

To be honest dude, without an extended battery man that's about the best you're going to get. I consider myself a moderate-heavy user and I work from 8am-5pm. My battery is unplugged at 7am and when I get off at 5pm its on about 20% on my way home. I've tried just about EVERY rom(aosp/sense) along with EVERY kernel combination out there. I browse web, constant text, twitter, Facebook, email, maybe a game and I've never witnessed anything greater than what I posted above. No matter what people say to you about how great their battery life is or how its been running for 18hrs its all BS(w/ reg battery). Yeah if your phone is sleeping 90% of the time then yeah its believable, but for users like us 6-8 is about the best with a normal battery. Now a buddy of mine has the sprint extended battery; dude uses the hell out of his phone and can honestly say his phone last about 17 hours of power usage.
My tip would be to invest in an extended battery if you want more than 6-8 hrs.

Lol this is far from the truth. I avg 18-20 hrs with moderate use.

Define moderate use! My screen on my evo gets turned on like every 5 or 10 mins while wifi usage sits at 40% and the screen is constantly at 50%. My phone lasts me through work with pretty moderate/heavy usage(7-9 hrs) and I'm happy with my battery simply because it's not going to get better(regular batt). Now if your display never gets passed 20% then you're not using your phone buddy.But, if you're using a REGULAR battery and you're actually getting 18 hours feel free to post pics or no one cares to hear about this make believe 18 hours. Please do share how you actually use your phone; how are you achieving such great results cause as of right now you're just one of those randoms who come in and say **** like" durrrr I get 18hrs on my phone, but I post no pics to back it up". PICS OR IT DIDN'T HAPPEN

The best option I could suggest would be search E-bay for a 3500 MaH extended battery. They run about $.01 with about $9.99 shipping from China. If you need help I can send you a link to one of the auctions. Also make sure things like auto-brightness isn't enabled and that things are syncing a ridiculous amount of times per day. Good Luck.

Ive been running CM7 for a couple weeks battery life started going down hill fast.
My fix was to get new HTC battery for $7 on Ebay problem solved.

Just try turning the Google backup off.

I get from 10hrs to 15 but I turn off the day when I'm not using it and have my CPU set to run a at different speeds

Bro I bought a 3500+ battery from eBay and it lasts me about the whole day, this is with the exception with 3G on and heavy texting, moderate browsing and heavy and I mean "heavy" application use during the end of the day. On other days when I'm not texting I'm watching videos on youtube with the 4G on, this last for about 30 - 60 minutes top!. So whats my point? Say thing like you said, "My tip would be to invest in an extended battery if you want more than 6-8 hrs."

Im not sure what kernels are being used that are tossing out such ruff battery life but SavagedZen-1.0.0-CFS-HAVS-WiMAX-GB-noSBC is treating me right.
Simple performance setting in CM changing governor can get the job done adding many hours of extra battery life.

Smartass setting is great performer to say the least power packed battery saver.

Not sure if apps available but it would be nice if governor had timer settings were user could set what governor they want to run at what time automatically.
Example would be after 11pm power-save governor kicks in then returns to Smartass from 7am - 12pm etc.
If such apps available...maybe I'm missing setting in CM someone please let me know

Closest you're going to get to that is setcpu man. It does just about everything you just mentioned. There's a donate version in the market and a free version that the dev puts up for xda users try google search you'd find it in a heartbeat.
Actually I'm feeling nice. The latest version is 2.1.1.

Actually I'd say its pretty simple enough in cm7 and I think it should probably stay that way to be user friendly to the not so savvy rooter lol. But above you stated you wanted more control of your kernel pretty much; setcpu gives you total control. You can set a diff governor profile for diff actions(plug, unplug, screen off), battery percentages, etc. I'd say give it a shot.

TIPS for Improving Battery Life

Hey guys, so i've noticed that a lot of people are complaining about their battery lives. There are a few things that I have done which are not too complicated that I think the rest of you should do too (if you haven't done so already). With these steps, i have my brightness almost to the max the entire time, and the battery lasts me most of the day without needing to charge.
1) Calibrate your battery - This first step is a given, and should definitely be done, especially after rooting. You can find steps by searching in the forums for how to calibrate battery.
2) Uncheck "Use Wireless Networks" in the Locations menu in the settings. This is a huge battery hog, if not the biggest on the phone (next to brightness and 4G). If you feel like you need it to use the "Places" app better, then you can either always turn on GPS just when you need to use it, or just search for whatever you want in Google Maps directly. Many ways around this problem.
3) ROOTED USERS ONLY - Get a root explorer, go into /system/apps and move the following apps to a different folder, preferably on the sd card: Socialhub.apk, Mediahub.apk, Sprintzone.apk, SprintID.apk (sometimes called w_sprint.apk). Obviously if you use those apps, dont move them because you'll essentially be deleting them, but from my experience most people don't use them, and they are always just running in the background. Huge battery hogs as well.
- You can also delete the other sprint apps through the usual app removal process if you'd like.
Also, if you use widgets such as Beautiful Widgets, or Minimalistic Text, for time and weather that require Use Wireless Networks for updates, it would be best not to use them. Especially BW, drains a good portion of the battery. There are other alternatives that I feel are just as good, such as a decent looking modded stock digital clock and the genie widget from ICS (Thats what i personally use). They take a fraction of the others and provide the same information.

Very nice tips. I didn't really like media hub and got tired of seeing it.. but the sprint files you mentioned weren't in my folder.. The apps are still there
EDIT.. also can you like me to battery calibration instructions? O didn't even know that was a thing...

You can also freeze those apps if you are rooted. Same results

I am always so surprised to read people with bad battery life. I have a stick phone running all sick items except having root and I well easily get well over a full day on my battery. I plug it in asst the end of the day with 60% battery on a regular and that is after 14-16 hours. GPS always on, brightness on auto, sync what needs to be synced, using the phone as a phone, with Bluetooth at times as well. The only time I lose significant power is when I use Netflix or start running games for an hour or so.
Are people running stock on this or a built ROM? Also, are you running stock kernel with CWM? CWM put my battery into a hole so I went back to stock without CWM, no idea why out would do it though.

Examples of battery life.

It seems to me like from those pictures that you barely use your phone for other things than making calls. The reason that i can come to that conclusion is because your display battery usage is just so much less than your Android OS, that just means your screen is off for the majority of the day. I'm assuming from that that you're probably an older gentleman who has less use for things like texting and Facebook. Unfortunately, the majority of my communication is through those 2, as well as some other channels.
And to answer your other question, i am running stock rooted without cwm.

I guess i can just describe it for you, its pretty simple. Just follow the following steps:
1) charge your phone to 100% (if it reaches 100 unplug it then plug it back in, it'll most likely take another 20 minutes to truly reach 100)
2) if you are rooted and have clockwork mod recovery, boot into recovery, and wipe the battery stats. Then continue to the next step. If you are not rooted, dont worry, just go onto the following step anyway.
3) from the market, download a battery calibration app and calibrate it.
4) then use your phone regularly throughout the entirety of its battery cycle (don't plug it in for mini charges until it fully dies)
5) when it dies, recharge it back to a full 100% (don't unplug it before it reaches 100%).
Then you're done.

I wouldn't jump to that conclusion. By the end of a 16-hour day, I have about 2-hours of screen-time, and my battery is around 50%. I have corporate email on my phone, so it wakes up frequently, and I check my messages all day long.
There's also the issue with Android OS taking up way more of the battery charts than it's supposed to. Most of the time, that bar is 2x longer than my display bar, unless I unplug it and play a game for four or five hours. There is a bug on this phone, that either calculates the Android OS bar improperly, or the phone is genuinely using tons of battery in the background and Android OS is a giant battery drain.
If you hang out on the forums a bit longer, you'll see this pop up pretty often.

lol, I've actually already read those forums before, but the thing is that I just don't think its a bug with those people. The thing is that its simply a balance. If your screen is set to a very low brightness, or just off most of the day, it clearly won't be the main battery drainer, but all that means is that something else will be. Something will always be the main battery drainer, even if its not draining that much.
Maybe it just makes more sense in my head than on here, but I'm pretty sure lol.

That's even better with showing you all his awake time.

It is in fact a bug. Here is a bug report in Google's bug tracker. Here's another. There's also a very long XDA thread that explains what the Android OS bug actually is, and how it works.
If the lines are proportional, then Android OS is using more power than 2 hours of display time, and I've gone as high as 5 hours and 30 minutes. I've had times when 4 hours of screen time is still less than Android OS. What? That makes no sense.
From the XDA thread:
Same network, same location, same signal strength, same ROM (Changing my font maybe fixed it....) , same wakelocks between them, same background apps running. Not even 5 minutes screen time on the two. The only difference with .14 patched kernels I'm experiencing is that it's not showing up anymore in the stats, but it drains just as much as in the right screen, showing the same CPU state behavior. It's also happening less often, and many say it's not happening at all anymore, but how would they know it it's hidden now?
Click to expand...
Click to collapse
Before that were two screenshots. One of them showed a minimal Android OS bar, while the other had it at 95%. The only difference was the patched kernel. This. Is. A. Bug. Period. High Android OS usage means absolutely nothing. Even after tracking down wakelocks, it will be high or low pretty much at random. Sometimes this is a legit stuck suspend, in which case rebooting is the only fix. Other times, it's just the bad profile. There's no way to know unless you study CPU spy, better battery stats, and possibly Watchdog.
In any case, read that XDA thread that explains what Android OS is. It has very little to do with how much screen time you have.

wow, thats crazy.

I'm not trying to bash you or say I get bad battery life. I just don't see someone who is taking his or her phone out every 10mins getting emails, and calls, social updates, background syncing is going to get 10hours of battery with just about 95% left.
Maybe if all you do is check emails and take 15 min calls and put your phone back into sleep mode you can probly get that. But even then. I can't say real world usage = 10hr with 95% left. only if you have a extended battery on
From my Samsung GS2 E4GT

This is with an hour of screen time. Admittedly, that's less than half my normal usage, but I was working on my book on the train instead of reading reddit. I'd normally be in the 50's by now with about 2.5 hours of screen time.
Way better than my Eris.

I'll bite. First off, detail your setup. modem, kernel, ROM.
Second, from your graph it doesn't look like you are in a good service area, how many bars do you usually have?
4+ in screen time. At 4% left.

Sorry i could have sworn i uploaed a picture of my setup. its now the third picture.
i usually have around 3-4 bars. at that time i was at work but that is a constant drain home or anywhere else. at home i get much better signal.

Have you ever had reasonable battery life, or is this a new issue?
It's possible that your battery is bad, but I think it's unlikely unless it's been under high temps for an extended time.
Some suggestions I'd try if it was me;
- backup your sd card and reformat it
- try running calk 2.8.1 without the ics theme to see if usage improves
- run your setup without wiping/flashing for a few days and see if the phone settles in
Good luck getting it sorted.
Sent via EM waves.

When I first started, I was getting horrible battery life. Like 50% loss in 4 hours. Here are a few things you can try.
1. Turn off auto sync to google
2. Turn off facebook and sync
3. Turn off email syncing
You get the pattern. I think for me it was the fact that I was in a horrible reception area and all of the syncing made the phone constantly try to get a connection. Now i get 5-10% loss in 4 hours, which I'm happy with.
Kernel and modem are important too, so might help to tell us what you're using exactly.
Hope this helps.

EL26 and EL29 Kernels/Modems were huge battery drainers for me.

My set up is calks 2.8.1
Kernel: Desperado flashed yesterday
And modem El 36.

You ask about having strong cell signal, I guess it will drain the batter if you're going in and out of service? Just curious because on my way to and from our shop there is one spot where all phones drop service. It only lasts about 1/8 mile but it happens with every carrier I've tested.

Like someone above said turn off all syncing also keep in mind that phone batteries now dont hold the first 10% of a full charge because that damages the battery in the long run. The first 10% always goes down that fast unless you bump charge which is when you plug in to 100% then unplug and replug for 5 minutes and repeat a few times. If it continues to die like that then try underclocking with setcpu while you have it with screen off or in a phone call also you can undervolt. Turn off auto syncing and check to see what proccesses you have running that eat your battery and kill them.

How long does the battery last to an almost full discharge? I had the same problem when I flashed a new ROM and tried calibrating the battery as you did (deleting battery stats file). I'd unplug my phone after a full chatge and 30mins later would be down to below 90%.
Turns out that deleting the battery stats file may not do anything to our phone in terms of calibration, and the way to calibrate it is by doing a battery pull for half an hour or so. Then just using the phone, and the battery eventually calibrates itself. Can't remember the link where I read this, but after doing that and after a couple weeks of usage, the first 10% drop wasn't so dramatic. I currently get a day with an average of 3-4 hour screen on time. Using the same ROM that seemed to give me problems in the first place.
Also like someone else mentioned, phone signal is a huge factor in battery usage. One of the cell towers went down where I live, and during those 7 days (yeah, thanks sprint!), my phone would constantly jump back and forth off of roaming... battery life would tank so quickly that I turned off data/3G/4G to get any semblance of battery life.
