I've got an issue with my evo that it will randomly start not sleeping when i turn off the screen. ive got no radios on, and no internet and i am befuddled as to what is keeping it up. the battery was lasting exceptionally well a couple of days before the update because i took off all facebook syncing (that was causing my battery drain). now its back to belly flopping to zero as fast as it can when its supposed to be sleep.
ive tried turning off gtalk, ive got no radios on. at first i thought it was a syncing issues, because i was checking accounts and syncs, and one of my gmail accounts was constantly syncing contacts, and error'ing out. so i turned off sync contacts and its still awake when i turn off the screen.
Im just putting it out there to see if anyone else might have noticed such things on their evo. im still searching to see what could be keeping it up, but for now, i am rebooting as i write this to see if that helps.
i'm sorry if this is noob, but i've recently taken into increasing the epic's battery. i'm trying to use wifi more and i'm doing the sleep policy never thing. but i don't think i get push emails anymore when the phone is locked (screen shut off). This is normal right? that wifi turns off when the screen is off, even with the sleep policy off? I'm kinda a freak about the push email - i like having it instantly. Thanks.
I leave wifi on 100% of the time with it set to never sleep and still get email notifications. I hear them start to come in every morning before I get out of bed.
Hey forum ! , I was an iphone 3gs user and made the jump to android when the play came out.
Ive noticed my battery is draining 2-3% an hour and looking at the "battery use in setting and then looking at the graph it show the phone is randomly awake even when the screen is off.
My play is rooted using gingerbreak 1.1 and has mostly all the bloatware removed.
non of the apps i have installed ask for permissions to prevent standby, I only have tune in radio, mobo player, facebook, twitter adobe pdf viewer, fpse, snesoid, gameboid google maps youtube imdb touch calendar es file explorer unit convertor and ringdroid installed.
i have 12 processes running using 86mb of ram
all apps are closed properly, wifi is off, background data is enabled ( but no applications i use in the settings allow auto refreshing of data)
The battery life of my xperia play has never been great (lasts about 24hrs with just checking facebook, twitter and xda forums using the built in browser)
I just wonder what is causing the phone to keep waking up randomly, is this the culprit of the battery drain?
I have a couple of theorys .... i did install desktop visualiser to change the icons then once they were changed i deleted the app (i read this app causes battery drain) maybe this could be a cause i thought deleting the app would fix,
2nd i travel around as part of my job so i wonder if the phone is going through areas where there is poor connectivity and its constantly trying to connect to different networks causing the drain.... but does anyone know of any efficient lightweight apps that disable this when the screen is off.
lastly I think the could it be widgets i only use the built in ones with the phone, the wifi on/off gps on/off and data on/off
do you guys turn data off during the day to save battery and do you turn background data off ? i think its anoying have to change all these settings off to sqeeze a tiny bit more of juice out the phone, it probably uses more turning them on and off avery 1hr or so
any suggestions or setups of how other people have got there phone up and running with good battery life would be a real help
cheers !
Deleting all widgets certainly saved my some battery, also deleting the SE launcher with launcher pro seemed to save me a lot of battery but I'm not sure about this.
2 to 3% an hour isn't bad with radios on at all. When you say awake, do you mean the screen is on, or that it's just in standby? There is nothing in battery stats that say "awake" you need to be more specific on what the system says, not what you think it's doing.
If the screen is coming on "randomly" then it could be an incoming txt, email, phonecall or something like that. Lower your screen timeout in the settings to help there.
If its phone idle or standby, then again 2 to 3% is nothing. That's 30 50 hours of standby receiving emails, txts and what not. Nothing to complain there.

Click on settings then about phone then battery use then at the top of that screen there should be a set of numbers saying how long the battery has been used since the last charge, click that an it displays a graph , on the graph page it shows when the phone is "awake" by awake I mean the screen is off the phone should be in standby mode but its being acessed by something i.e a program , like its woken up to perform some action. Anyway im wondering if anyone elses phone is awake randomly when the screen in off and in standby mode. When I factory reset I neget had this issue but its after installing apps I think or some setting im missing any ideas
I have the same problem. My Xperia Arc is "awake" all the time. Screen is locked, turned off but in battery usage I see that the phone is awake even with screen off. The culprit seems to be the native messaging app as it consumes the most battery. I'm not sure what is going on, what is the messaging app doing or which process is using it.
Any ideas anyone?
I have found the solution for MY large battery drain:
The problem has been, that my phone used 5% of battery per hour when it’s merely lying around. The battery graph was a straight, quickly decreasing line. So the culprit was not something that happend from time to time but always.
One very disturbing thing: The indicators below the battery graph shows when phone, Wifi and the screen were on. In additions it shows when the phone has been awake.
Even if the screen was off and I did not touch the phone, the „Awake“ indicator constantly showed every minute for a very short time. So the phone never went to sleep, it woke up constantly all the time. Sorry, unfortunately I don’t have a screen capture for this.
Deactivating automatic updates for applications and setting the Emails to sync never didn’t help. I even erased all the Samsung crapware from the system folder, but to no use. The battery died after one day of not doing anything with the phone.
Then I deactivated syncing of the contacts and the calendar for my WindowsLive-Exchange account and the battery drain stopped. I now have less than 1% per hour (see screenshot) when the phone is simply lying around.
So, for me the culprit is the syncing for contacts and calender via Exchange. Unfortunately there is no option to set the sync interval for these.
- Anyone can reproduce this issue?
- Is this just a problem with WindowsLive Exchange or does this happen with other Exchange accounts too?
- Is there a possibility to set the sync interval for contacts and calendar (somehow, maybe via a config file)?
There seems to be something seriously different if not broken in GB 2.3.3. Apps that work perfectly fine in Froyo are keeping GB 2.3.3 from going to sleep. I've isolated several apps that either keep the screen from shutting off or keep the device constantly awake even when it it's no longer running/cached/screen is off. And, these are programs that work perfectly fine in Froyo and do not cause idle drain. Wonder if this is something 2.3.4 addresses...

I have frozen:
social hub, email (i use another one), and few more programs that I dont use but noticed that they stay on without any reason,
if 3G or wifi is ON battery drain is prery bad, I guess this is a bug in 2.3.3 as cmd512 said.
Last night I turned off wifi and 3g and made sure that wifi share + manager are off (they can be turned off easily if u untick "use wifi" in location settings menu)
so with everything off for 7 hours sleep (dont rly need my phone while sleeping) battery was down 2% only :O
the moment I turn on 3G Android OS use jumps to the skies :X

Hmmm..it could be. I will try this also. First I just take the contacts out, because that is not so necessary for me. Calendar is pretty necessary for me and emails are a must. If I have to take the calendar out, then so be it. I will manually sync it once a week then.
By the way, I just noticed that with my gmail account the sync icon is constant in the calendar.
Now when I unchecked it and checked back it went away after a while.
I am not sure if it was sycning all the time without luck. Lets see.
I think calendar synch is on of the probleme. With calendar sync my phone drain 5% per hour in idle mode without 1% by one or two hours.
It's quite strange that there's quite a lot of these threads now all saying about how bad the battery is but I'm amazed by how good the battery is. I don't use my phone a huge amount especially at work and when I get home I use it for a quick web browse and the occasional text message and phone call. Most days I will still have 80% or more left by 23:30 having been on since 07:15. Today I checked my phone at 12:30 and the battery had only gone down 1% in just over 5 hours. All I did with it from 07:15 was occasionally take it out of sleep but not unlock it to check for any notifications. Since then I've been using the web (data) for about half hour or so, an hour of music listening and texting and right now I have 77% left after 12.5 hours off charge. Therefore I think my SGSII has the best battery life I could ask for.

Really depends on what apps you have running, as you can see from my original thread on this "Awake all the time during idle" issue:
http://forum.xda-developers.com/showthread.php?t=1094666
But in general, agreed. Once I got rid of that bug, the device has been fantastic with battery life. And, for a stock ROM, that's damn impressive!

I fully agree. Now that I don't have the "wake-up" issue anymore, the battery lifetime is almost as good as the Omnia7 -that's damn impressive for a modern Smartphone with such a hardware!
For me, I turned off my wifi, gps and "my location". And most importantly, my applications are not running when it is on idle. Go to task manager by holding the home folder and click exit all. Or you might try to clear the ram memory.
i have turned off gps, wifi and syncing but still getting battery drains can´t even last for a whole day. But I installed Litening ROM just now and see if this helps . I was on KE2 before flashing custom rom

I have noticed the same issue trying to sync to a exchange 2003 account. It seems that my calendar is syncing either every minute or about every 20 minutes. I also noticed the same issue with my gmail calendar. I have tried two different phones and reset each one several times. The same problem keeps occurring. I may have to download touchdown for email, contacts and calendar. It just sucks because then I will have two calendar applications (one for work and one for home). This is very frustrating.
Are you still having issues with echange calendar sync?
After updating to KE7, I have noticed that every time I receive an exchange email the screen wakes up for a second or two and goes to sleep again.
Didn't occur on previous firmware. Anyone else with this issue and a possible fix?
Is social hub the best solution for IM? I would like to have Yahoo and MSN messengers on always, so should I use another less power hungry client? When people mention calendar synch is it google calendar they're talking about? My google calendar is important for me, so how to optimize it?

Yes, unfortunately. I am now syncing manually with a switch on the homescreen.
I am now hoping for Android 2.3.4 to fix this issue.
Have a look at comment #290:
http://code.google.com/p/android/issues/detail?id=11126#c290
I have an X10i with Jerpelea's CM7 with custom kernel and that had a very annoying deep sleep issue (the phone never went deep sleeping) which caused the battery to drain very quickly, but Temoi19 found out that by disabling automatic time updates and manually selecting the operator, made the phone to deep sleep. So I took a shoot and tried the same trick on my new Galaxy S II and now when idle my phone barely eats power. After over an hour after unplugging I was still at 100%. I don't know if I am just lucky, but it is worth a try

I also have this issue with my sgs2. I looked into the exchange settings and there is the option to change the syncing. It was set to push, I now i changed it to manual and will report back the results tomorrow. The drain in general only occurs when mobile data is enabled here. Didn't try with wifi yet.

You can leave the syncing to push, it's just for the EMails and they're working fine.
I'd propose to disable the calendar and contact sync in Einstellungen -> Konten -> Automatisch synchronisieren

according to the logs if there are no changes in contacts or calendar both will be synced only once per day. so this should not be the issue.
I've noticed if I leave wifi on overnight, it drains about 30% battery.
My wifi sleep policy is set to never. The only apps supposed to use network is autosync from Calendar, Evernote, Gmail, Google Voice.
I'm using Darkside CM7. Is this normal?

Im pretty sure it is. having your wifi on is just like constantly having 4g LTE on, except maybe not as bad. Your phone is constantly connecting to Wifi/ trying to find a Wifi signal, so even if you have wi-fi on, and your not connected to wifi atm, it will still drain battery. If your using wifi, turn your 4g off so it doesnt burn twice the amount of power. same thing vise versa.
Is there a way to let it activate autosync once every hour but have wifi turn off rest of the time to save battery? I don't have a data plan so I can only use wifi.

Hmmm, 30%? If you were using stock, that would be normal but you are using CM? Thats definetly weird, have you checked your OC settings, that might be it. Also, you might wanna try setCPU to underclock it, it really saves a bunch of battery.
Under CPU settings I have Governor: interactive, Minimum:245, Maximum 1024.
When I have wifi off, it only uses 1-2% battery when I wake up.
