Huge battery life fix.

I am using the stock radio. This has been confirmed by others as working also.
Seems as if there is some sort of bug with with Cell standby that causes the phone to lose signal which in turns just kills the battery. To verify that your set has the problem, check the Cell standby info in the Battery Use info. If the Time without a signal is higher than 0% (50% seems to be the norm) than you have a problem.
One solution, at the moment, is to follow these steps:
1. Plug in phone charger or into USB.
2. Put phone in Airplane mode
3. Put phone to sleep for a minute
4. Turn off airplane mode
5. Unplug phone
My Time without a signal is at 0% for over 16 hours now. The battery life is much better and the phone didn't die on me last night while i was sleeping.

I am using the new Radio and mine was @ 58%. I will report back with any change that this makes.

Also testing. Mine was at 32%.

Didn't work for me
I am running the stock radio and after following the instructions cell standby was at 0%. 5 minutes later, I am back up to 46% so I guess it didn't work
Tried it twice with the same result.

Ok, followed your steps. Using the new radio, after 2 min with the phone in standby, I checked again. Shows it sitting at 40%. So I dont know.....

same here...it's back up to 48%

I tried this and after 10 minutes of standby mine has dropped from 56%% down to 30%. What exactly does this fix do and does it have to be done after every reboot?

Well i tried it and thus far it's had no effect my cell standby is back up to 40% was at 50% it's been climbing steadily.
Perhaps someone can correct me but it was my impression that "Cell Standby" was NOT time without a signal but rather cell time spent doing nothing but communicating with the towers. Since the phone is always communicating with the towers then it's going to show a high percentage of battery usage.
I imagine the reason you are seeing less % with Cell Standby is not because your saving battery but rather other applications (I don't think they all show) are using more battery time.
Anyway I don't know this for fact, but it makes a sense to me. Perhaps someone else can comment on this.

You need to press on Cell Standby to see Time without a signal , this is what kills the battery.

Were not talking about cell standby, were talking about time without signal, which is a huge battery drain, and is under the cell standby category.

Myth busted!!!

Thanks for the correction, however I did go under Cell Standby and I do not see the settings you are referring to. Perhaps there is a ROM difference (damagecontrol 1.0) or maybe I don't have any time without signal.

I did it one more time and it worked this time.
I'll keep my eyes on it until tomorrow and see if there is a difference.
OP, do you have to do this after every reboot?

Mine also looks like that without showing Time without a signal for a while, at some point it will start showing 0% otherwise is will show like 50%.

That's a pretty big assumption. One that's unsupported IMO.
My "time without a signal" has been exactly 50% since I installed DamageControl. My battery life is no worse than it was with any 1.5 ROM. I don't think this is an issue.

I can tell you that my battery life for 18 hours yesterday was better then it has been. I also know that if you have no signal the battery drains like a mother. I don't know if all phones have this problem but I have a phone "without Google" on it.

ill give it a shot i was at 50% so cant hurt

I have noticed that eventhough my cell standby time has decreased the time without a signal is still at 50%.

HAHA Well without any fix at all Cell StandBy = 5% - Pretty good if you ask me.
BUT
Street View is at 89%- ROFL I haven't used Maps.Nav in 2 days!

My Time Without Signal was at 58% before doing this (the Cell Standby was somewhere around 60%).
After doing this 1.5 hours ago my phone does not display a Time Without Signal.

No Signal = Battery Eater!

Noticed a severe problem on my Desire!
I went on a camping trip yesterday, and just got back a few hours ago.
And my battery life has been terrible!

I had 99% battery, put the phone to sleep in my pocket, and 2 hours later, I had 86%!! I never touched the phone! and I use governors for the phone to be at 122-307mhz ..
another 2 hours, and then it dropped from 86% to 74%!
I noticed both times the phone had no signal, as I was up in the mountains... It must have been the battery eater!
So the phone dropped from 99% to 74% in 4 hours on standby! After that, I decided to put the phone on hibernate..
Previously, if I left the phone on standby with signal at home, it could get me 8-9 hours before it drops from 100%-99%!
Phone is currently charging. Bit disappointed!
(Note: in my graph, it shows I had GPS on, but I only used it for 5 minutes, when it was at 100% to drop to 99%. I also had ALL data connections off, apart from the phone on)
Anyone have similiar expierences?

Low signal is a battery eater on all phones. If you have no signal, it has to search for a signal source more often, I certainly have this on my Desire S too.

Agreed. If I know that I am in a no-signal area and I really need to preserve battery, I either put the phone in airplane mode or switch it off completely.

latest radios sux big time if we speak about signal.. phone lose and search signal very often..and u can see some times 1 some times full signal bar and sometime no bars at all.

Thanks for the replies guys
I'm currently on the radio from the OTA .4 update...
Guess I'm now gonna upgrade to the .5 one, as that too has heavy drainage!
Cheers!

Aeroplane mode on all sense roms that i've tried on this device use about for times the battery that normal use does, air plane mode use =18mA compared to 5-8mA with phone and wifi on (these figures are obviously from a good reception phone area and connected to wifi with a strong signal, it's difficult to test in a bad reception signal area where I live)

If you know that you're going to be in a poor signal areas then it's a good idea to switch the phone so that it only receives 2g signals, add thus will reduce the about of polling that occurs and therefore reduce the waste in battery use
Obvious but daft, if going camping where's you know you'll have little to no signal then it probably pays to simply power down the phone when you're not going to use it

That's curious, thanks for the info.
Must admit, I've only used airplane mode briefly when I specifically needed to use some other function on the phone, so I guess I never noticed the extra consumption.
It sounds completely counter-intuitive that it used more power, but you have clearly got detailed information!
I can certainly say for sure though that switching the phone off completely extends battery life loads

*#*#4636#*#* > Phone information > Turn off radio

Oly I've noticed this problem too. I normally keep my phone in my pocket at all times.
While operating for fractures, we sometimes wear lead aprons to protect us from xray radiation which emanates from the image intensifier.
These are 0.5 mm sheets of lead which block out or attenuate all radiation...including phone signal!!!
I had noticed that if I go in with even 95% battery, by the end of 6 hrs my battery would come down to 10% to 13% without ANY use!!! So I started leaving the phone out on the table and no more battery drain...!
I'm on stock radio by the way. Heard bad things about the battery drain on the new one even with normal signal. I could be wrong...I'm just quoting the opinions of people who've used it.
So I guess in any situation where signal is poor the phone goes bonkers trying to scan for a stronger signal and kills the battery!!!

Oh yeah. Confirmed it does here. Playing with RCMix as of last night. Odd, I wonder how you get to testing mode now. I'll investigate.
To Oli: Can't remember if you use Tasker? If you don't remember to switch off 3G, set a profile to drop 3G when outside the radius of your town/city and signal strength drops below 'x' dB for 'y' minutes as long as screen is off. That'd work too.

http://en.wikipedia.org/wiki/GSM
"The transmission power in the handset is limited to a maximum of 2 watts in GSM850/900 and 1 watt in GSM1800/1900."
If the phone is trying to communicate with a base station and having to transmit at that kind of power to reach it (in poor signal areas) it's going to drain your battery pretty quickly...

I can confirm, I also work in an area with poor coverage and it normally ( with stock 2.3.3 rom) would come down from 100 to 10 % in about 8 hours on standby..
Now I have changed to Proxuser 2.3.5/Sense3.0 it has improved but still very unhappy with the lifetime though. I would like to have 3 days at least with moderate use.
Here is a screenshot of the 2.3.3 drainage.

[Q] Battery life. SKYICS rc7.3 ~ 9 HRS 43 MIN max charge.

I've had my skyrocket for about a month now, and I've had horrible horrible battery life compared to all of you guys on here. I've tried reflashing, did the whole .3e recovery/ wipe/ fresh install tutorial that Seanz posted. (Amazing rom by the way.)
Nothing seems to work. I've calibrated my battery at least 4 different times. Oh, and for Seanz, You say your rom is 2.3.5, but in my settings it says 2.3.6. My brightness is all the way down, My data, bluetooth, gps, etc are ALL OFF! Only thing I keep on is wifi, ALWAYS. I've tried leaving my phone off the charger all night and locked to see if the drain was the same, and it is, If not just a tad less drain. I'm sorry if I didn't clarify this good enough, If someone could help me out I'd be glad to explain myself better!

Does your phone maintain a strong to moderate signal (both data and talk)? This includes the strength of your WiFi connection. I've noticed one of the biggest (if not the biggest) drain on this phone and most others comes when the phone is strugling for a decent connection. If you can, try this: put your phone in "Airplane" mode for 1 charging cycle. This means your phone won't even try to get a wireless connection of any type. To be safe, make sure the "WiFi" is off as well. See how long the battery lasts compared to it not being in "Airplane" mode. If it still sucks, you might need to see which app(s) are draining your phone. If it is noticably different, a weak signal might be the problem. Good luck.

He changed it only in text for certain apps that require Android 2.3.6, even though they'd work completely fine on 2.3.5. Somewhat an easy workaround. Also took some of the features from 2.3.6 in. It's still built from 2.3.5 though.

Thiiiis is probably your big issue. If you have any apps running in the background that use data, they can keep the wifi awake, which, in turn, never lets your phone sleep. If you go to Settings>Wireless and network>Wi-fi Settings>Menu Button>Wi-Fi Sleep Policy, and set it to "When screen is off," you'll be AMAZED at how much life it can save. I've noticed drastic differences when that setting is applied. As far as without it losing around 10-15% overnight to a mere 1%.

Thanks for your replies! I'll try you guys' ideas out now. I seem to lose about 1-3 percent every 10 minutes. I'll put it in airplane mode and try it for an hour.
Thank you Fortune! was wondering how to do this, You could have just solved my problem. I'll keep you guys informed! I'm amazed at this communities helpfulness. Thank you!

No prob!
Though, next time, if you have a question, should post it in the Q&A section of this forum. People tend to get a bit pissy about seeing Q's posted in other places, haha. Just giving a heads up!
Hope those fixes fix your battery life! That wifi sleep on has been key for my 30+ hr battery lives on SkyICS.

Seemed to not help :| Since I've done this, It's gone from 22% to 17% in about 15-20 minutes. No apps running, etc.

Try downloading CPU Spy from the market place and after awhile of letting it rest (about an hour or so), open it, refresh and check to see the CPU uses the "Deep Sleep" frequency at all and to see which frequencies it spends most of its time in.
Also wouldn't hurt to check Settings>About Phone>Battery Use to see what's using most of your battery life. Display, Android System, and Android OS typically hold the top 3 spots, so if anything is up there (or at a close 4th), that app could be what's bogging it down.

I downloaded CPU Spy and it seemed to already have data for it and it says 4% in deep sleep, 65% in 38 mhz, 5% in 810 MHz, and 1% in 1026 mhz, 17% in 1728 MHz

Alright, well so far so good. Shows it's at least getting some deep sleep and able to idle in low frequencies. Can't really get TOO well of a reading until it's done some time with it idling though.

Do not set wifi policy to screen off, keep it at always. this will keep your data using wifi when connected which is way less of a drain than the 4g radio. Basically with the screen off policy your phone will still use data, it will just come from cellular instead of wifi when screen is off.
Also get this

It will tell you what is running constantly and draining your battery.

Since he has his data off, turning off the wifi with screen off will benefit him greatly. It would be stuck on otherwise. Noted:

Ohwow.... That's....... Interesting, haha. If I notice my wifi is on for extended periods of time, my battery starts draining a bit faster than normal.
Might have some app in his background either keeping the phone awake or just hogging background data, keeping the wifi constantly active.

the real issue is when i actually stop being on wifi. when my phone uses data connection, mostly LTE because its everywhere around me, the battery life becomes miserable. I left the house for about 1 hour today, you can clearly see it on the graph. I should try to cut all connectivity and just allow the phone to sync every now and then, im sure ill be able to add another half a day at least to my already 1.5 days with wifi on all the time

Yeah, data is a KILLER. For me, it's usually wifi or nothing, unless I'm trying to send or receive an MMS, or need to quickly access the Internet, but I turn it back off as soon as I'm done, and I set my network to no LTE because it's not in my area.
Just take that as a note OP, lol.

[Q] Who's to blame for battery drain?

My phone went from 90% batt to 0% in 5h of screen off time. Usage shows Android OS 60% and SopCast 30%.
When i locked the phone i left it on the home screen.
So who's to blame? The rom, kernel or the app?

could you please provide a bit more detail like what kernel or rom you have and also if you could upload screenshot of battery usage

Rule out your application first. I'm assuming SopCast is a podcast application? If you were streaming, that will explain it. And yes. We need more details.

Anyway this is no longer related to that obscene 90% overnight bcuz i uninstalled sopcast. Now i just had 16% drain overnight (with Wi-Fi off) which is still a lot imo.

Having 18% drain overnight on JB with wi-fi off. Any ideas?

Why are turning wifi off in the first place? That is stupid if you're trying to extend battery life.
What is your cell signal like. A crappy cell signal drains battery. A crappy 3g signal that is constantly on because you turned off wifi drains even more.

i was under the impression (from gingerbread times) that wi-fi uses up more battery than 3g; this was among the tips you would find back then on android sites to extend battery life.
Anyway, i have yet to find out who is calling the AlarmManager that is keeping the device awake. Any idea how i would go about doing that?

Hi, like the other guys said that are trying to help u....
We need more information to try and help u figure it out.
What ROM?
What kernel?
Any other modes or tweaks?

I didn't mention that info so far because the initial problem of this post is fixed (SopCast (podcast app) keeping phone in stream mode) by uninstalling the said app.
Now, i believe that the overnight drain on my current JB ROM is too high.
So, here it is: Rom is Grean Bean ( http://forum.xda-developers.com/showthread.php?t=1821478 ), kernel is Matr1x 22.5 (but the drain didnt change when i changed kernel (beladus, _thalamus, air) and the significant mods that the rom has are V6 supercharged and brainmaster's twks.

That was not the case in GB times or any times. Either you read wrong or the sites are stupid. Considering that for the most part the android sites / bloggers are still idiots today, who knows.
Anyways. WiFi uses the least battery. Less the 3g/2g. Should be used whenever possible to save battery. Phone in active use or idle you should be connected to WiFi over cellular data. Turning all radios off but enabling WiFi is the most battery efficient thing you can do and still have data but you won't have the actual phone. I do that at my buddies house where I get no service at all. Not going to use the phone for a couple hrs use airplane mode. That uses very little power if the phone is sleep. Turning the phone off and on uses more.
Also the better your signal is the less power the phone will use. You still gave no signal strength info. Frankly you're wasting your time with better battery stats and wakelocks etc when you don't fully grasp this radio stuff. Use that tool when you need to find something that keeps your phone awake when idle/not in deep sleep.

That's the situation i'm in. It seems i've solved it by figuring out which apps were calling the AlarmManager and the Media server, there were 2 actually: Latitude and Google Music Sync, that were waking too often. Now i've simply disabled them.
I didn't give any signal strength info, bcuz i didn't move and didn't change the radio. It's a jelly bean thing for sure (i have google now disabled). Many users have been complaining (in various rom threads) about this new found drain after the upgrade.

Yeah, I normally play with a new ROM bare boned to see if has a natural drain.
Then I add the apps that I have been using that I know do not drain battery life.
And the other person is dead in with the signal advice. I had a HTC hero before and it had many tweaks on fixing the signal so battery would last. Which is why I love the pull down notification bar and some ROMs have idle timers.
Good luck

[Q] MAXX High Battery Usage (High Android OS Usage)

Hi I have a just got a MAXX and updated to 4.4 without root. I found that my battery is not staying up as long as it should, it lasts for like 18 hours. The following are the details:
- Canadian user, Fido sim card, exceptionally bad reception (3 bars tops indoors) (My Phonto Q / Razr Maxx gets full bar when I plug in the same sim card)
- Screen On time at about 3-4 hours
- Rarely turn on data
- Rarely Game on Phone
- Non-rooted
- I keep wifi turned on, connected most of the time
- Use apex launcher instead of MotLauncher
- Active Display, Touchless Control on
- Location Services are in "Battery Saving Mode" (Meaning the phone uses wifi and mobile network to estimate location)
Is anyone else experiencing the same problem? If so, is there any solution? I see a similar thread made early but that is for the Ultra, and even the ultra got around 12 hours of discharge time
Edit: So far based on doogald 's reply, I suspect its the poor reception thats draining the battery, the following photos shows the reception differences across different devices with the same sim card

How long have you had 4.4? When I have updated or changed ROMs, it seems that it takes the software a little bit of time to catch up getting to know the battery.

That's a little more drain than I would see for the same screen on time. Bad signal will definitely drain a battery faster. Forget about stupid bars - what is your signal in dBm? (Settings->more (under Wireless & Networks)->Mobile networks->Network type & strength. Also in settings->about phone->Status->Network type & strength).
The number will be negative. For GSM or CDMA, anything less than (more negative) than -100 dBm is a bad signal and the phone will amp up the antenna to try to pull in signal.
Based on your battery screenshots, though, it's probably not bad signal - I think "cell standby" would be a higher drain if that was the case.

I have had 4.4 for exactly 10 days now, i think everything should be settled by now
My signal is around -97dBm, and it jumps from that to No Service. I dont understand why this phone have such terrible reception though. I had two other phones try the same sim card and they have excellent reception.

So will you say the phone have a bad reception in general? Or is it just because I am not with Verizon and its being s b**** to me ?

Question- are you rooted and using xposed framework? Things that heavily mod the stock system, like GravityBox or Xblast can easily have that affect. Even smaller things like the smooth progress bar can hit it. The more changes, the harder the system has to work to keep up

I have terrible reception at home and work and am getting 7 or so hours of screen on time. Constant switching between 4g/3g and sometimes to 2g.
I'd suggest trying a program like betterbatterystats or similar to see if there's a wakelock keeping the phone from going into deep sleep mode (processor shuts off) when the display is turned off. Also cpuspy will show you if it's deep sleeping. It won't deep sleep while charging btw, this is normal.
For me the problem was the Facebook app. I disabled it and not only did my battery life significantly improve, but so did my productivity Info about wakelocks, if you're interested - http://developer.android.com/reference/android/os/PowerManager.html
Pain in the butt but there's always the factory reset option too.

PowerManagerService.wakelocks is the sum of all your partial wake locks, so you need to look at your partial wakelocks

Not sure why this worked, but it did. At least through one day of testing
I ready elsewhere on Droid X forum someplace I think about draining the battery completely until your phone shuts off and then recharging. It's supposed to re-calibrate it. Sounds sketchy at best I know, but it seems to have worked!

I did this with my ultra followed by charging to full and did a factory reset. My phone seems to be normal again.
