After you do that, turn off the "Always On Mobile Data" option. I still get push Gmail (the stock mail app that I use for MobileMe doesn't work hourly, but syncs when I open it and randomly without sometimes). Everything else works normal, but when your phone is locked nothing but Gmail, text messages and app alarms that use Slacker/Pandora work just fine. Pandora stops between songs (I listen while I'm setting up my work station) just hit the top power button and it'll resume.
I get about 30 hours with moderate usage. Checking about 10-20 emails per day, listening to Pandora for about an hour or so, checking some web pages, a few text messages, few photos and maybe playing Angry Birds for a bit is my moderate usage. I also keep Bluetooth off unless i'm in my car and I stream to my radio, gps is off unless I use navigation (I still use the tower triangulation for correct weather) and Wi-Fi off.
Sorry for being so long. Hope that helps.

[Q] Battery starts draining at exactly 5am.

I started using JuicePlotter yesterday, and noticed that at night my battery barely drains, if at all (hooray for setcpu!). Until exactly 5am when it starts draining heavily at a steady rate. I've done all of the obvious stuff (I think), like making sure I have nothing set to begin syncing at that time, but I can't seem to pin it down.
Does anyone know of a way to find out what's turning on at 5am and draining the battery?
Do you have an Exchange sync setup?
If you do you may want to check and see if your Peak times start at 5AM. If so you may want to set it to update less frequently.
Does JuiceDefender run on a schedule and keep 3G off until 5am?
Thanks for the suggestions guys
I have exchange set up, but its set to "as items arrive" for both peak and non-peak hours (which is set to 8am anyway - yeah, being on call 24/7 sucks).
I'm also not using any kind of timing app like juice defender to schedule anything.
One wierd thing I noticed that may be tied to this, is that certain apps like twitdroyd and fb update immediately when I open the apps, even though they're set to refresh manually, and not to update when I open the apps. Still trying to figure that one out.
Night mode is enabled from 2 am to 5 am. Depending on your settings, Data/3G/Wifi are disabled between those times.

This sounds promising - can you tell me how to check any night mode settings? (searching turns up nada)

He is referring to JuiceDefender, I bet. I would guess a lot of people who use JuicePlotter also use JuiceDefender. It does exactly as he described: turns data off from 2am to 5am. I use it, and it does help. It also keeps data off when the screen is off during the rest of the day, except for a quick check every so often.

rats - I was hoping he was referring to something in regular settings. I'm not using JuiceDefender, or anything similar.
well if you do have it setup for everything to be off between 2 - 5 then wouldn't that make sense that as soon as 5 hit your apps will start syncing even Google apps as they have been trying to sync that whole time and just started queuing up and finally your radios turned back on. I have not used juice yet so i do not know much about it just throwing in some pennies.
One other thing the refresh manually is only for when the app is closed as soon as that app opens its going to sync with its servers. When you set it to manual then that means when you open the app you manually refreshed it and the phone did not do that while idle or you were busy on some other app. Its like twitter for desktops if you set your refresh manually then while the app is open it will not refresh until you hit refresh

One thought: Do you have a good signal in the spot where your phone sits at 5am? A bad signal is the best way to drain a battery fast. A friend's house has an awful Sprint signal, and my battery will drain in four or five hours there, even with no use, whereas I get well over 24 hours with average use in good signal strength areas.
Back when I first got my phone, I used System Panel to figure out what was causing the battery drain. I liked using it so much, I even ended up purchasing it. The history part is what you want, and it will work without paying for a bit, so you can find the problem.

that would make sense if I was running something like that, but I'm not - as a part of my job, I need to be able to reply immediately to specific emails. At any hour. Total PITA, but hell, it's better than not having a job, right? JuicePlotter's pretty neat though - it just sits in the background monitoring your battery levels and graphs them. For example, it was showing an almost horizontal line from when I stopped using the phone the night before until exactly 5am when it started a gradual decline.

Are you sure about this? I mean it makes sense, but I would be willing to swear that back when I was running stock I would open FB or Twitdroyd and it would wait for me to hit refresh before syncing with their servers. Twitdroyd, for example, I would set to keep 80 tweets, and I would check it only occasionally, so I could read those 80 tweets whenever I wanted. Now when I check it, because it syncs immediately, I lose anything older than the most recent 80 tweets. As a workaround, I've increased the number of tweets to keep, but it's still annoying.
ok so hmm what rom are you using. not wanting to bash the dev but could it be that rom?

My signal's not great, but the phone didn't move between 4am and 5am, and the battery only started draining at 5am.

I actually purchased SystemPanel this morning with the hope that it would help me get to the bottom of this (I had been using the free version for a while, and now I had an excuse to buy it). It shows me history of battery, device usage, and cpu activity, but even if I see that the cpu or the device is being used, I'm still not sure how that's going to help me pinpoint what's going on. First I need to build up some history anyway though.

Anyone Using Tasker?

Anyone here using it? what is this app for? is it worth buying? does it give u battery life? im really interested but i cant find no videos on it on youtube. please share your thoughts.
It is worth every penny. The best app for android IMO. It is not very easy to master it, but even the basic stuff has made a vast difference too the behavior of my phone.
For example, I have extended my battery life to 38 hours simply by having it automatically go into airplane mode between midnight and 6am.
It will turn off wifi, back screen brightness down, change screen timeout to 10 seconds and give me a notification popup and sound when my battery drops below 15%.
It will turn on gps when Wavesecure is activated, something Wavesecure can't do by itself.
It will turn my ringer off when I get within 200m of the two cinemas I go to.
It turns wifi on when I get home, and off when I leave. Same for work.
It loads my music app when I plug my headphones in.
Tasker can make widgets! I have one set up to (with one press from my home screen) turn up screen brightness, turn on gps, turn up speaker volume to max, wait 2 seconds, then launch google navigation. It will then turn everything back when I exit out of navigation.
It will, on weekdays, text my girlfriend at a certain part of my journey home after work. That way my dinner is ready when I get home!!!
I would say try out the free 1 week trial. There is even a wiki and web site with extensive instructions and examples uploaded by other users. You can also import profiles as well as create your own. The really handy ones I have exported to my sd card, and e-mailed them to a friend when he bought Tasker. Not sure I helped him though as there is a steep learning curve for this app, and it is worth being patient with it to learn its ways for yourself.
I think it is worth much much more than the asking price.

wow sounds sooo nice . i already bought full version yesterday but havnt even opened the app once . well i did open it once it seems hard to understand lol . so for all this task does the gps need to be on? or not? and can u turn off 3g?
You can turn off APN, but don't think that works well in the UK. Sorry, my knowledge of 3g is limited.
Basically, you can have tasker turn on and off nearly any feature of your phone that your want. There are two sides to tasker. The "Profile" and the "Task".
I have found it is best to first set up the "task". Say you want to save battery power at night. Select the task button and select "new". Call it "power save" or something. Select the + symbol and select "Net". In this menu, pick "Airplane mode" and select to ' on'. Then hit ok, then save.
Now to create the 'Profile' where you define the contexts that will activate the "power save" task you just created.
Select 'new' then select the 'time' context. Enter the time you would like to have your phone go into airplane mode. After hitting 'ok' it will take you to the profile page where you set up what now happens between the times you just specified. From the drop-down at the to of the page, select the "power save" task you created earlier. Hit 'ok'.
Done. Your Tasker will now shut off all your radios between the times you entered.

Worth every penny. I use it to:
- turn on GPS for programs that need it (turns back of when editing the program)
- turn notifications off when starting desk clock
- change volume when connecting head phones
There are endless possibilities, try it and then buy it.
i've bought it for little things but want it to be able to handle 3g data which it doesn't
i,e turn on wifi, if no conn after 10 secs, turn on 3g, auto sync for a min, then turn data off.
works fine and dandy with wifi, but not 3g.

You need APNDroid to disable 3G.
tasker really is worth every penny!
Wort every cent. Must have
I used to check periodically (every 3 minut) if my car Bluetooth near. If yes connect and and hold on the connection. If disconnect wait 15 minutes and seek again... save really battery... fantastic...

Wow sounds like you have a good understanding and has some good stuff. I don't know if you can, but I posted a page where maybe people can leave profiles for those of us who are a bit more chronologically challenged.
This is the greatest
I use tasker for everything. I am very forgetful so I have it pop up astrid tasks when I leave the house or work. The quiet mode works well for work and there is even a way to auto check in to foursquare.
Worth every penny, it makes your phone 10 times better and is a must have app.
I have profiles that do the following:
-During work hours and within range of the office set Vibrate, turn off wi-fi.
-When within range of home turn on Wi-Fi
-If at home after certain time in evening go silent
-When leaving car (detected by bluetooth connection to stereo), store time and location. Have icon on desktop to retrieve info and show on map to find car.
-When on call (by checking diary) if a colleague calls always ring regardless of silent.
-Say caller/texter name
-Send magic packet to wifes phone to report location and show on map (handy when shopping)
Plus many other scripts....
I find that this program has a pretty high learning curve...
Is there a wiki I can read up or a way to import other people's profiles?

Using "Cell Near" instead of GPS
I was using Tasker to turn WIFI on and off based on GPS locations. However, I found an alternate method that does not use GPS calls (and waste battery use). Instead, I am now using "Cell Near" to find the cell tower near home and turn WIFI off when I am not within distance of it.
I have posting walkthroughs of all of the most useful profiles I have collected. Check it out at http://dbilliter.blogspot.com
Tasker rules my phone... With all the taks i made.... Love the app!!!
You can do almost everything if you know how to use it... Little variable programming and your phone will get his own life haha...
GREAT APP

Anyone having issues with 3.29.651.5

I am running stock 3.29.651.5. Ever since I updated, my battery performance has decreased, my web browser has become very choppy, and overall, the phone just isn't as responsive. The previous build ran beautifully on my Evo. Anyone else having issues?

PEACE,
YES!! It appears that my browser cant even get some pages (or it takes forever to load ---for instance XDA). I use Gtalk (I know most of you consider it BLOATWARE) and i barely can connect or 3G or 4G. My best connection is Wi-Fi which is good--when I'm home...not so good when I'm at work. I've ran the wimax test on my phone through Terminal Emulator and it stated that my wimax keys are still in tact and i have installed the latest radio...*shrugging shoulders*

I am running rooted stock (myn's I believe) with no issues... my other evo is stock 3.29 and had battery issues for the second and third days running but has since smoothed out....
Edit... using Sprint Lovers stock-ish 3.29 from over at ppcg
I have rooted odexed Rom and I can't rip out the Sprint bloatware. It's driving me insane. DC 3.6 can't come fast enough

I'm definitely having issues with gtalk..I can always connect via wifi but for some reason 3g has issues. I can connect with other 3rd party apps though, like beejive and trillian.
I am also having some issues. Used to get around 20hrs or so under moderate use. Now it seems to be more like 12 possibly 16. I get a very weak signal at work and this new update seams to drain much quicker. been thinking about rooting. Have done a lot a reading but not 100% sure how to do it yet.
same problem here. So I read elsewhere to check your Accounts and Sync in the settings. The update reenabled sync for stocks, weather and peep....which once I turned back off, my battery is fantastic!

I can't signin to GTalk since the update. I cleared the data, but that didn't help. What exactly does GTalk do?
Yeah already turned the sync back off. Gonna try rooting with unrevoked. Seems pretty simple to do.
I have had stock everything since I purchased my phone, no rooting or anything and have never had any issues with my phone at all. Since the 3.29 update, I think my phone is actually running better. The screen transitions on all my programs seem smoother, even the 4G load animation is smoother. Battery life is the same as before, crappy but I use my phone ALOT for work. I just don't know if I am just lucky or it is becuase I am using the phone as it was intended from Sprint.

Just a question, not being a smart ass, but what made you join these forums if you haven't done anything to your phone? I'm truly intrigued by the different things I can do, and I like reading about what I can possibly do.
I've been having an issue with audio applications.
If I pause a song or podcast (whether it be in the stock Music application, Google Listen, or Audio Book Player), leave the application for a while, and return there is a very high chance the song or podcast will restart from the beginning. Likewise if I do the same in Pandora the application fill crash on me.
This is mostly annoying because 90% of what I listen to on my phone are podcasts and lectures. Not being able to easily pick up where I left off is irksome.
Has anybody else had this issue?
have you tried pulling out the battery? i had alot of problems with the phone after update and so did my parents. after i pulled battery it starting working alot smoother and battery life has been alot better.

Well normally you would report bugs to the app developer, in the case of apps. But in this case I don't know, because I haven't had any of these problems. Haven't done any podcasts but I use Pandora, last.fm, or Slacker radio for about an hour a day. I use it for a half hour on the way to work, pause it since I don't use my phone at work for anything but phone calls, then play from where I paused it 8-10 hours later for the half hour drive home.
I'd try a hard reset. Sometimes updates don't work smoothly. Just look at the Sprint forums shortly after the 2.2 update. Tons of issues that were fixed shortly there after by a hard reset. I haven't noticed any issues, and my battery seems to actually last longer, when the screen is off. I just got 12 hours with several phone calls, wifi, bluetooth, GPS, maps, navigation (for a short time), and the biggest battery drainer: games. Still had 12 percent, and it probably would have lasted at least 4 hours if I just let it sit. I leave all my email push and have facebook sync enabled.
Anyways, from my experience, nothing seems broken, its faster thanks to no fps lock, overall better performance, and the battery lasts longer, though it seems to run down a bit faster when in use compared to before, but it barely loses a charge while sleeping, so standby time makes up for it. (as long as you let it sleep, which in my experience, starting with the G1, is the real secret to best battery life. Let it sleep as long as possible. Constantly messing with it, switching the screen off, only to pick it up five minutes later is horrible for battery life. Use it, let it sleep, pick it up again in an hour. If you can that is...)
Was pretty choppy until I flashed netarchy kernel. But still getting alot of FC on Internet, when I use the back button it FC.
I had issues at first but after time and 2 or 3 reboots, all is smooth.

Yup. I use acast for podcasts and noticed that right away. For the life of me i can't figure how the update could have caused this problem.

Poor Battery Life

I am getting very poor battery life. Fully charged at 8am and dead by 5:30. Hardly even using it. I have a limited number of apps on, just a subset of those on my Nexus One and no rouge ones at all. Made a few calls, no web, a couple of gtalk posts and that is it.
See attached usage screen charge to dead and charging again!
The phone is useless like this... any ideas????
Are you in a building with poor reception? I noticed this issue when I left data on when my company moved buildings.

Is that solid blue bar from your WiFi being on all the time, or is that your awake bar on 100% of the time from a bad app?
That battery life looks atrocious. Show us the second screen to see the "awake" times.

I am not sure what you mean by awake bar?
I keep wifi and bt on all the time, as I did on my old N1. I am in the same place in the day as I was with that and will have same reception, which is not bad.
App installed are not strange at all;
Adobe Reader
Android Task Killer
AL Voice Recorder
Amazon MP3
Astro
Google Authenicator

That's it, like I say a sub-set of those on my N1 and all solid apps.
I normally listen to mp3 on the N1, but have not had time on the Galaxy yet, so it;s getting less use.

When clicking on the graph, there is a blue bar showing how often/when the phone is "awake", like in the screenshot I've attached.

do you keep mobile data turned on? if so, do you keep 3G turned on, or just 2G?

Get rid of the task killer!
Other than that, don't see anything crazy... This battery life is really strange. When your screen is using less power than the 'Android OS' it shows you're really not using the phone much, but the phone is still tanking on battery life.
I'll post those screen shots for today when I get home tonight.
A few things I have noticed though. It seems to level off at midday, this is when i leave work and go home for an hour. While at home I will be on wifi. I do not connect to wifi at work.
Secondly, while at work I notice my data often changes between "3G" and "H", while the phone is in the same place. Probably 60% H and 40% "3G". It is not practical to turn "2G" only on, as I get the volume bug and the phone becomes unusable.
I am wondering if the data signal is draining it somehow? If so, how can I work around that? Like I said, I have a N1 before the GN which sat in the same place on my desk every day and had no battery drain issue at all.
I unplugged mine yesterday at 7.30am and it died at 9pm
I used the internet on/of all day made a couple of calls and about 50 texts, screen on time was about 4 hours.
Today i've used it in a similar manner and as of now (3pm uk) 7 and a half hours in its on 57%
The battery in this thing is better than my desire, granted, not much in it but it will easily get a normal user from one sleep to another

No, it's strange you have a task killer on Ice Cream Sandwich. WTF? This isn't Eclair. Get rid of the damn task killer.

I'd say with 95% certainty it's just signal-hunting causing the drain. With my Fascinate at work, I'll easily lose 50% battery within a couple of hours, even if I'm not using it, while at home it'll last me between 15-20 hours before getting low. Easiest solution is to just buy another charger for work, and leave your phone plugged in whenever it's on your desk.
Don't like seeing android os at the top of that list! Does the nexus share some of the problems that have plagued the galaxy s line of phones, the android os bug!? :O

I kind of think you might be right. However, a phone that drains itself while doing absolutely nothing useful at all, is no use to me. I carry it about and am in and out the office though out the day. It would be unworkable to keep putting it on charge every time I come back in the room. I need a phone I can carry around for a working day without charging. My old N1 did. If this can't do it I'll need to get short of it and get something more practical. Seems ridiculous though.
Btw, task killer just got installed by default when I upgraded. All the apps that were on the N1 were installed when I signed in. Just never deleted it
Do you leave your Wifi on all the time even if you don't have Wifi signal available? Don't do that.
If you are too lazy to manage your data connection manually all the time, I highly suggest getting the app Juice Defender from the market. You can save the battery by setting a schedule for data connection and also it will disable your wifi automatically if your phone can't find a wifi spot it can connect to.

Yes, I leave wifi and bt on. I want to be able to do this. I am not asking for it to run for days. 1 full day is all, I have not issue charging every night.
I could look at the juice monitor, however, it does not seem too much to ask to be able to get 1 full day from it of average use. To me, it seems perfectly reasonable to expect the device to work for a full day with all services running.
Is there any tool than can be used to prove that the signal hunting is eating the power? Currently is seem to be in the big pot called "Android OS"??
Well, I'm not gonna defend the phone. Leaving all radio processes on, especially when there is no signal available, is well known to drain a lot of battery since the phone uses more power to search for available networks than when it has a stable connection to one. If you leave it on in a place with spotty or no signal it will make the problem worse.
Juice Defender (the basic one anyway) is free and pretty much manages the connections for you and basically extends your battery life with minimal effort. Give it a go for a couple if days.

I strongly agree with chrono.

+1 with Chrono.... Turn off Wifi completely if you are not using it.
if you are a new android user, you should also check the settings of the phone:
hit *#*#4636#*#* in the dialpad.
this will bring up a menu. there you should try phone (i think, my n1 got stolen a while ago). there, you scroll down and there is a menu to adjust the preferred network mode.
if it's set to CDMA preferred, it will search for a cdma single. you just adjust it (i think) to gsm only. google will help you a bit here.

best setting for juice defender?

just got juice defender ultimate, as it seems to do a good job of making my battery last longer....but there are so many settings, i'm getting confused.
I basicaly just want the best settings that will disable all internet to save battery, except for once every hour when my i want the phone to run the "autosync" process to sync my facebook, twitter, emails etc. i alsao want it to obviously allow me to connect to the internet if i manually start an app which needs it (internet browser, facebook app, peep, etc).
at first, the app seemed to be doing this, but now i'm finding that although it's doing a great job of saving battery, it's not syncing, and my internet connection doesn't come on when i open an app. (or occasionally, it will come on, then not turn off again until i manually tell it to.....which defeats the whole point of having jhuice defender...i got it so that the phone would automate this process).
any help greatly appreciated...
totally given up on these battery saving apps now. they all seem to do the same thing...
they work exactly as they should for a couple of hours (i.e. they cut out internet except when syncing or when needed for an app etc)...then they suddenly jsut stop working, cause my internet connection to be lost completely, and i can't get it back until I reboot my phone (losing temp root i might add, so having to go through that whole process again too).
i think i'm going to just suck it up and charge the thing every day...i bought an "extended battery" which is supposedly 2430mah (around twice the stock battery), but it doesn't seem to give twice as much performance....it just seems to slow down the battery drain slightly for the first half of the cycle....
i.e. it lasts for around 2 hours without going below 90%, then within the next 2 hours it will drop to 70%, within the next 2 hours to 50%, the next to around 20%, then finally dying within the next 2.....
this is with syncing on, occcasional text or email checking etc.
so i'm getting around 10 hours use instead of around 7 or 8. it's better, but it's far from being twice the capacity.
but anyways, yeh, battery saving apps jsut seem to kill my internet requiring reboot, so i'm gonna just manually cut internet at various stages through the day from now on, and keep charging every night? sound like a plan?
Green Power Premium.
Simple and works as advertised...Juice Defender has got a lot of settings for sure...

ok, i'll give the free version a try...but i'm not holding out much hope, i've tried so many of these battery saver apps now, they al result in my internet connection being totally screwed up until i reboot the phone.
The default settings are pretty good. I don't think I changed much in the way of settings. Your phone will save a lot of power throughout the night with this.
thanks! finally, a battery saver that actually works!
been trialing this today and so far so good.
7 and a half hour shift at work today, it's been syncing every hour (which i know has been working, cos on my break i had tweets and emails waiting, and again when me shift ended)...sent a few texts in the morning, on lunch and after work too. so far it's down to around 83% battery....
The important thing is that it hasn't destroyed my internet connection (touch wood). It switches it off until i unlock the screen, except when it periodically turns on to allow the syncing. It also knows when I am at home and will use my wifi instead of mobile internet.
I'm going to keep trialing it for a few days to make sure it definately doesn't crash my internet after a while like the other programs seem to. So far so good though. If it keeps working, i'll buy premium for the night mode feature. Save even more battery that way.
thanks again, very happy
No problem. Glad it worked out for you.
Green Power is no longer working at night mode....switching WiFi and mobile networks works still, but it doesn't seem able to switch to airplane mode. This is only since I rooted, but I'm on stock Rom and this appears to be the only problem now.
::EDIT::
apparently, someone else on their forums have the same issue, and it's a known bug, something to do with green power being "paused" then "resumed". weird how it's never done it before though :s
have uninstalled it and reinstalled, so hopefully that will sort it out :S
::EDIT::
worked perfectly last night, so it must have been a one off glitch :s
