The reason I am asking is I am trying to track down a battery drain issue. The only thing I think can be causing it is the fact that I have my phone set to check 4 different email accounts every 5 mins.
I have a 3000mAh battery and I am able to kill it in 8hrs. I seem to remember someone talking about an app that could tell what apps or services were causing the most battery drain?
I am thinking about doing a test where I turn off automatic email checking and seeing if the battery lasts any longer. I use the phone for business as well as private use so I need to keep track of things when someone needs to get a hold of me. So I use email a great deal.
Ya.. that seems pretty fast.
I would also recommend checking the radio version that you have. Some people say that some radio versions kill the battery faster than others.
Check that out.
I have push mail set for one account (MS DirectPush with an Exchange server) with a 4/5 minute update interval, and I get acceptable battery life... It's not fantastic, but what do you expect for a PDA smartphone As soon as I fire up pRSSreader to check four RSS feeds (even if I set the interval to 3 hours!) my battery life REALLY suffers, and I'm in a 3G area - close to a mast, stationery - all day every day. The Palringo client REALLY kills the battery, we're talking about 3/4 hours to get to 10%.
SPB GPRS Monitor is useful for seeing if there's any data throughput going on, and the BatteryStatus Today plugin is also useful for seeing current battery drain in either mW or mA, so you can kinda figure out what's going on with your phone at the time (that and acbTaskManager to see if there's any processes maxing the device's CPU out, which has caused me battery drain in the past). I've got a HERM with v1.05.05.00 radio, for the record.
I've been having the same issue with my Vario II...
The battery life was relatively good when I didn't have my web'n'walk connection enabled. But now I have DirectPush enabled to check emails on an Exchange server set for 'as items arrive' aswell as another three POP email accounts.
The GPRS is almost always on and on full charge will only last me about 8-9 hours from 100% charge. If I'm out for a continous stretch for more than that time- I'm in trouble (as I was yesterday!)
I'm guessing this is normal behaviour then? Not too good if it is (!)
Well I went from 4 accounts every 5min down to 1 account every 5min and my battery life doubled. So yep constant email checking does kill the battery. Oh well, I have my important account set to check every 5min (may change it to 20mins) and my other accounts set to once a day, which I usually just check manually when I have a few min.
There seems to be many other threads on this issue and some say, even with multiple accounts setup, battery life is in the region of 20hrs. Changing to a different [radio] ROM seems like one of the solutions.
Sorry guys...I know I'm kinda late joining this discussion, but I thought I'd put in my two cents...
Checking your EMail in the fashion you described in your first post definitely drains your battery. I was in the same situation you're in: about 4 different accounts, set to update around 30 minutes or so...my phone was beeping "low battery" before the afternoon was over (and that was after being charged the previous night!)
Not only that, but I'm convinced that the "always-on" state that the radio was in from all that EMail-checking is what caused the radio to "burn out." I had to get a new 8525 after that happened.
Good luck with your situation. I'm looking for a solution myself.
hi,
I would like to know how often you recharge your Hero?
With moderate to low usage I'm recharging every day and I'm thinking that autonomie on my Hero is really very bad. Before I used Polaris and I had to recharge every 2 or 3 days.
I'm thinking that maybe my phone have manufacture default. On official web page they say that autonomy on standby is 440 hours, its like 15 days, mine keeps barely 1 day, wtf!!!
Even during night when I don't use it all and put on plane mode battery loses 20%.
whitealien
i recharge everyday with mild usage. gaming - usually keep it plugged in.
with moderate usage i recharge my GSM Hero every 2-3 days. by moderate i mean, like 1h Wifi, 2h mp3, 0.5h phone usage, 1.5h online activity over 3G.
Thats about it. And even if i multiply the usage above by two, it will last two days.
During flightmode inthe night, it loses about 5-10%.
so it seems something is sucking really bad on your battery!
Cheers,
Chaos42
I would say I charge mine every 2-3 days. I'm a relatively low user but wifi is on all of the time and I use it for browsing a bit in the evenings when I don't have my PC turned on. GPS, mobile web and bluetooth is off for the most part.
My wife has the same phone and her battery life is a little shorter than mine but she has the mobile web on and uses hers a bit more then me so I would guess around 1.5-2 days.
My battery is rated at 1350mAh which I think is standard.
I have to charge it every day.
Unplug it from charger at 0700 and by 2200 it has less than 10% battery.
But I have WiFi on for over twelve hours a day, mobile web on and quite a few things updating online!
Background apps may be draining your battery
Hi whitealian,
Check the application list to see which applications are running in the background. One of them may be draining your power.
You can check the task list using Estrongs File Explorer (start the app, then menu->Task Manager). There are plenty of other task managers, of course...
In my case, I think it was ShopSavvy that was running in the BG. Once I removed it the battery performance was much better. See this post.
You can also use one of the apps that turn on/off wifi based on location. A quick market search finds "Y5 - Battery Saver". Haven't tried it myself yet!
Good luck!

Thanks for advice. I was not using ShopSavvy, but I had doubts that either I got faulty device or some app is draining battery.
I called customer service and they advice me to put phone in safe mode and test it for awhile. It extended a little my battery life, but still recharge every day. Next step was to reset to factory default. This is what I did yesterday and now I'm at the end of second day since last charge and I still have 40% left, what seems to be normal, but still a little to early to judge that everything is good.
I still don't know from where battery drain was coming. Probably from some app.
I'm putting my bet on NewsRob - google feed reader. It was the only app that was using network in background (apart from mail and tweeter sync).
too often. mostly once a day.
but when i'm at home im ususally plugging the as adaptor in either way, because i'm afraid to have to little battery left if i leave the house without a 100% battery level. (this can happen fast if you sync a lot of rss feeds, surf the net, have an exchange server connection and gmail push and so on...)
They really need to make better batteries. They should last 2-3 days on full force usage.

I wish it could
I think once every 2 days, but at night I have the ''phonestuff'' turned of using it as an alarm clock only. I do use the mobile internet connection all day. Tried once without that and got almost 4 days out of one charge.
I agree they have to make better battery's but I don't think the hero's that bad.
I had a diamond wich I had to charge almost twice a day when data was on...
So for me the hero's a big improvement.
I too get 2 to 3 days use out of a charge. Got rid of standard HTC Twitter client and replaced with Twidroid Pro. Only have Gmail push synchronization on.
I am pretty sure you are aware if the standard HTC SMS app battery drain issue?
Someone pointed out that HTCs SMS app constantly drains the battery, because it stopps the phone from entering standby mode. You can replace it by going into Applications menu, open "Messages", "Clear defaults" and install HandCent. As soon as a new SMS comes in, it will ask you which app you want to handle SMS messages. Choose HandCent, make it default and you are set.
Gave me a huge battery performance boost.
every day. that is the only bad issue of my hero.
I charge mine daily when I go to bed as it's usually giving me the 15% warning about 24hrs after I last charged it.
The joys of smartphones
At least once a day.
I've got a desk stand so it sit's in that for a constant juicing up, when im in the car I put it on to charge.. At work its on USB charge.. Basically I just juice it whenever I can..
I dont think theres anything wrong with yours.. they just have bad battery life.
If you think thats bad try the fossil palm powered watches.. i have to take it off every couple of hours to charge it!
Too often. Exchange, gmail, 1 additional pop3 inbox, facebook every 2hrs, twitter every 2hrs is enough for my phone to barelly hold a charge for a day. But when actually using the phone (music, calling), it doesn't hold even a day.

That's a US only thing though, right? The European ones don't suffer with that issue AFAIK.
...Which I'm glad about as I sometimes have to charge my hero twice a day. Data is on all the time when I'm out and I'm a pretty heavy user of it. In terms of calls perhaps an hour a day, and not a huge number of texts (more than ten would be unusual). I do use the phone to listen to music quite often too.
I think the apps in the background thing is what needs to be checked. I use a news widget and Facebook and Weather and a travel one which I think adds up to a lot of refreshes. I'm thinking about making a Sense Profile (or whatever it's called) that has nothing on the homescreens at all for times when I might want to be a bit more frugal with battery life.
I do think it's somewhat ridiculous that the phone is capable of doing so many things but that if you have it do them it withers and dies. I would've thought the way to calculate battery life would be to have the phone doing the things that people will want to do with it and work from there. It seems that battery life is calculated by turning the phone into as dormant a state as possible and then tip toeing around it trying not to disturb it.
I get by though.

Well, I cannot confirm that. I have a European one and mine drained the battery. I searched the net and with this trick I came from ~1 day to over 2 days with moderate usage and push enabled all the time.

My battery went even better once I configured Locale to go into airplane mode during night time and stopping sync services during work time. I don't need push when I am at work (timescal set, no GPS), because there I have all my mailboxes open and directly connected.
Some more tipps to improve battery performance.
Disable 3G - Set to "only 2G" in mobile network settings
Set display timeout to 30s or lower
Remove as many widgets from your homescreens as possible (I only have calendar)
use task killer app to check which apps are still running in the background and try to tweak their settings to not autoload or don't notify you on updates - and of course kill them
disable screen animations
uncheck WLAN for location checking
don't check your mailboxes too regular
disable vibration totally. disable haptic feedback for the keyboard as well
I've had the HTC Aria for about four days now and my biggest issues is the battery drains to quickly. At first I attributed it to use because android phones prompt you to use them more often. However, even without use it still drains pretty rapidly. Does anyone know of a solution to this issue software wise. I have already turned off Bluetooth, GPS and Wifi. Are there other solutions
I got mine on Saturday, and I've actually gotten pretty good battery life out of it. I'm still in the habit of charging it every night, like I had to do with my old WinMo phone, but I think I could probably go two days without a charge. And that's with GPS / data always on, Wifi parts of the day, and pretty heavy use, since I'm always playing with it.
Have you tried something like Advanced Task Killer to keep apps closed that you aren't using? You can also adjust your screen brightness and timeout to try and save power.
It says that of my power is used by cellular idle or something like that 50% of it was used by that. Could it be my AT&T service
I don't get more than 10 hours out of mine. When I know I will be out all day, I turn the screen brightness almost all the way down to help conserve energy.
Good as it Gets.
With basic usage (some texting, a few calls and some market browsing or playing a game here and there) about 2 to 2.5 days without charging. Maybe the ones having issues with there phone sucking battery have to many widgets running.
In my current configuration I am only using 3 of my screens and only 3 widgets [favorites (small one), HTC clock/weather widget, and the HTC calendar widget (small)]. I have my work email checking every 30 minutes for syncing. I also have gmail and the default mail app pulling mail. I run ATK but only to kill apps on startup (cause it runs almost everything), other than that you don't need a task killer as you will have to reload these tasks next time and that will drain battery. I don't use it after that to kill anything. I am also running my screen at about 30% brightness.
Just some tips, widgets are nice, but they suck the battery life as well as constant updates. Check to see what you are running and disable/remove what is not needed or adjust sync times.
My battery life is fine. I got two days over the weekend with light usage. You need to look at what services are running and disable any widgets that you dont need. You may also want to look at the sync settings and turn off things you dont use (such as news). You do not need a task killer.
Also, see this post:
cranked said:
some quick tips:
1) disable market notifications - Market -> Downloads -> Notifications -> 'Don't Notify Me
2) Lower the sync times for your social network apps like twitter and facebook (or make them manual)
If you still suffer, have a look at some of the great tips HERE on the Cyanogenmod forums...ignore 1 and 3.

Also one might do *#*#4636#*#* then change phone setting from WCDMA to GSM .... Then that get little more out of battery...
It's critical that you turn off auto-sync; I have found that it absolutely destroys battery life.
Before I was losing maybe 5-10% every hour on standby, but ever since turning off auto-sync, I'm still sitting at 100% battery after 5 hours of standby.
Turning off mobile data/Wi-Fi doesn't make an impact on battery life, in my experience.

I edited your response..
Auto-Sync in itself is not going to be a problem.. Depends on what's syncing. EVERYONE will have different battery life because everyone uses their phones differently. Different configurations, different accounts used, different amounts of traffic on those accounts, not to mention actual usage patterns.

90% of people will have *slightly* different battery life.
5% of people will drain it fast.
5% will use it like a voice phone and might even get 16 hrs out of it.
But to turn off all apps makes for an invalid test because then you're testing the phone as if it were a non-smartphone, like a voice only phone.
I think the battery is too small for me and probably too small for most people. I look forward to fat batteries for this great phone.

My wife gets 2+ days out of hers... The battery is not that much smaller than my Nexus One, a more powerful phone, and I'm a power user with a lot of crap running including IMAP push mail, weather syncing... I look in at Market, Facebook, Twitter and manually sync those types of things etc.. I can easily get a full day out of it, off charger ~8am back on the charger midnight, 20-30% left. What I don't do is sit staring at my phone all day or play games for 8 hours at work, nor do I use it as a mp3 player..
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:

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

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.
Before getting the Note, I've been an iphone user ever since the first one came out. I switched especially because of the nice large screen which is handy for the type of work I do.
Some questions though:
1- Battery Life: I was pretty handy on the Iphone in getting everything I didn't need (some notifications, location services on certain apps) turned off to safe battery...while keeping only the ones I wanted. I haven't figured out how exactly to do this on the Note. My battery life is poor...at least compared to what I was getting on the iphone. I typically start my day at 8:30AM, and yesterday by 6PM the battery was already at around 10% (where I can't take pictures....)
2- Must I have GMAIL app and MAIL app? For some reason the GMAIL app's emails update much quicker than the main app I use MAIL. So when a new mail notification comes in I have to manually refresh the MAIL app for it to catch up with the GMAIL app. Otherwise I would have to wait a couple of minutes of the mail to show on MAIL app.
3- On Mail App I have two email accounts. Why is it that my welcome page is the page showing my accounts rather than my "ALL MAIL" page which is where I left it originally?
Thanks for sorry for the NOOB questions.
Ad 2):
Depending on what other email account you have there colud be an specific app for that provider that also supports push email (eg. Yahoo). Or you colud configure Google Mail to poll for mails from your other accounts.
1.) try to close auto sync, bluetooth, gps and use wifi everytime its available because 3G drain much more battery. and lower the brightness on ur screen to ur lowest, that can save a lot of battery (just open them when u need to use it)
or Root your Note and use custom rom. There are many roms that help you with battery.
hope that helps.

Battery - 10% in a day??! How much were you using the phone?
Allow the phone to fully charge and discharge for a full cycles. The screen is a big consumer of power - don;t use auto-brightness and keep the screen down to the best workable level for you. Also, the more apps you have using push syncing, the worse your battery will be.
Depending on what you're using the phone for, you should easily get a full day's reasonable use out of it.
I agree with the point shaoran_ojo made about wifi - but also turn wifi off when you're not using it.
Finally, it's absolutely right that many of the custom ROMs will give you better battery life
You can check the battery usage over time, if you go to Settings menu and then About phone -> Battery usage. You will see there what eats most power (most likely, Display).
Touch the chart in the upper part of this page to expand it - see if you can relate biggest drops of battery charge to some particular activities. For example, playing Crayon Physics drains the battery extremely fast.
Do you happen to be in areas with poor cell coverage? I've had phones drain like there's no tommorow in poor coverage areas, especially when GPS is turned on since most phones are equiped with assisted GPS chips that use cell-tower triangulation in order to get a faster fix on your position.
You could root your phone and switch to custom kernels or roms for better battery life as well as performance. A few ways in which you could then save battery are by undervolting or underclocking the processor or using an app like titanium backup pro to freeze battery draining apps. Wifi is also a big battery drainer. You can set the wifi sleep policy to screen off to curb its usage or keep it off entirely when you dony need it. Gps and bluetooth can be kept off and the screen brightness can be lowered. Im sure you wont be disappointed with the note's battery life after you tweak it right.

First of all decrease the screen brightness if possible. I have my brightness set to minimum and I have Screen Filter (free in the market) installed and set to 50%. This setup works for me when I am indoors and when I am outside I just disable Screen Filter. Hopefully it will work for you too, maybe with a little tweaking of the exact percentage.
Then take notice if your phone is unusually hot when you haven't used it in the last 5 minutes. This may indicate there is an app keeping your device from sleeping. Check the battery usage (Settings -> About Phone -> Battery Usage). Tap the graph and look for unusual drops and periods when the screen is not on but the device is awake.
If you notice something, BetterBatteryStats (paid in the market) might help reveal the source of the problem. Cpu Spy (free in the market) will show you how much time has the device spent in each CPU frequency.
If you are comfortable with it just root your device and install a custom kernel. I can't begin to explain how much this can increase the battery life.
Hope this helps and is not too hard to understand despite my bad english.
