Batery??

My mogul has to be recharged half way through the day? Im on it an average/alot but dont surf the net alot and I have installed teh x button so nothing is constantly running (or at least i think it isnt)
could i just hvae a faulty batery or is something goin on that is draining it?

The only things I can think of that are draining the battery are bluetooth being on, wifi being on, and possibly if you have it set up to check your mail very frequently. With wifi and bluetooth on even if you aren't actively using them they drain power cause they are constantly looking for signals. Other than that it should be lasting longer.

How do I change how often it checks my email?

are there any power saving tips? my blue tooh was on and turned it off and it still is draining.

To save power on the Mogul:
1) Turn off the data connection after using it using the comm manager. (Two arrows on top of the screen above the signal strength indicator.)
2) Turn off the bluetooth radio after you are done using it.
3) Turn off the Wi-fi when not using it.
4) Make sure all of your mail accounts are set to manual instead of automatically checking for mail every so often. This will keep your device from opening data connections.
5) Turn down the backlight when the unit is on battery power. I have mine set to the third lowest setting.
6) Set your auto shutdown time to 30s when on battery.
7) Press (don't hold) the power button when you are done using the device.
When I use the device in this way, I can almost get two days of regular use out of my device.
Hope this helps!

Do this!

I'll second the above poster's suggestion of changing your schedule for checking outlook. To do this, go into ActiveSync on the phone, go to the 'Schedule' option and change from 'as they arrive' to 'every 5 minutes' or longer. This will help a lot
Here's another thing you can try. It had HUGE results on mine. You will need to edit the registry. I will suggest getting Total Commander (this is a great file explorer as well as a registry editor, and a text editor. Basically, these keys disable the mogul's ability to manage the power management functions it has built in. changing them to a value of zero will allow it to manage power more effectively.
Before doing this step, I would be typically close to a drained battery by the end of the night, after doing this, I'm still around 60-70%
To get to the registry in Total Commander, go to the topmost level of folders. You'll see an entry with two slashes that looks like this - '\\' Click on this and you'll have three options, FTP, LAN, and Registry. Click Registry.
Go into these places, and change the following keys:
HKLM\Comm\AsyncMac1\Parms
- Change the key 'DisablePowerManagement' to 0 (zero)
HKLM\Comm\Irsir1\Parms
- Change the key 'DisablePowerManagement' to 0
HKLM\Comm\PPTP1\Parms
- Change the key 'DisablePowerManagement' to 0
HKLM\Comm\L2TP1\Parms
- Change the key 'DisablePowerManagement' to 0

thanks for both your replies, havent tried it yet but will. is there a "push email" program for the mogul that you guys know of that will allow emails to come through like that so there is no setting for the mail to be checked every so often? it will just come in when its there.

well, are you connecting through an exchange server, such as a work email account, or are you trying to sync with something like yahoo,gmail, etc?
if you have outlook at work, then you can set it up with activesync to push it out to you. this can be done on your phone's activesync program menu. then you can go into the schedule option and adjust how often it syncs with the service. many people set it up to 'as they arrive' which maintains a constant data connection, and thus drains more battery. thats why 'every 5 minutes' saves you alot of battery drain. make sense?

Yeah that makes sence. I used to have a black berry and the mails just popped in without having to maintain a constant connection (as far as I know)

battery life suddenly gone awry

hi all,
I've installed a raft of apps in the last few days (perhaps that was foolish) on my sim-free white Hero, and suddently the battery life has gone to pieces. It now won't even last the night *in standby with wifi off*.
Any ideas as to the known battery killers, or any way I can track down which is causing this? I don't really have to want to start removing apps at random and monitoring.
There's nothing particularly unusual in my list of running apps, following a power cycle (is there?):
Shake Awake, NetCounter, AK Notepad, OI Update & Countdown, Tube Status, Battery Widget, BBC News widget, Peep
(although that does raise a separate question: why do things like ShopSavvy, AK Notepad, start at boot, when presumably they're not really doing anything until you use them?)
Of course, I have other things that get started asynchronously, just not at boot, e.g. SMS Popup.
anyone got any ideas, please?
thanks much indeed.

I had the same issue when i put on battery widget, I saw the % going down while watching the phone.

oh! that's ironic
I do get the impression that it's more recent than that, but it could well be, I suppose. I'll remove it and see... thanks.

I've heard that the bbc widget drains the battery.

This is something Google should address with android market. The system should apply various forms of stress testing to all applications and rate them according to connectivity requirements, CPU load, power consumption etc.

I think for people who have a serious drain they need to hard reset and start again, put 1 program on at a time and leave it a day or so with that program on, finding out whats causing the drain.
Logically thinking, i'd expect it to be a program that is using internet in the background, like the bbc widget which could still be downloading without you knowing.

good points, ta.

I already noticed this. I checked the CPU load in idle mode and normally it should be around 10% (using "System Monitor").
Sometimes however, depending on what apps were running, it is increased to 30-40% and staying there constantly.
Closing all apps (incl. Sense) does not help either, the CPU load won't go down again until i make a complete device reset.
So i guess some processes are stuck in thise case causing the high load (and draining the battery empty).

My GPS did not disconnect, after foto geo-tagging, and that goes quick as well.
Also the BBC-app was installed, but got rid of it because I didn't use it. Might be a coincidence.

The BBC app polls really often. There's no setting to tell it how often to poll. It really kills the battery fast

I wonder though: even when the phone is in standby? something is killing me in standby. Oddly, it seems better if the phone is on
I'll try removing the BBC app overnight, and see...
then the battery widget tomorrow, etc...

Turn on usb debugging... download the SDK.. cd into tools.. and run
adb logcat
or to send it to a file:
adb logcat > log.txt
(and ctrl + C to stop logging)
Inspect the log file and you'll see what its upto pretty quickly. Maybe its overkill, but I fire that up when it starts behaving strangly.
EDIT: err to answer your question.. yeah the widgets wake the phone up to grab new data, which eats battery. The BBC news one seems to be polling reallllly often, which is unecesarily using power.

quick update: removed BBC News and Battery Widget (separately), no change; phone still dies overnight, in fact in about 5 hours on standby, from a full battery, to totally dead.
I just this minute discovered that my phone whilst in standby is still polling my IMAP server to try and connect, and I have a huge inbox, which it was prob failing to get the headers for. Seems like a possible bug that it still does this whilst in standby, but I've disabled that account anyway. It might be the cause...

What do you mean by Standby? Just inactive? Airplane Mode?

sorry, poor terminology, perhaps. No, not airplane mode, just the screen-off state it goes into after a few minutes.
It does seem a little bit of a waste, if the phone is going to spend all night checking for new Twitter, Gmail, etc, updates, when I'm not awake to read them? So I'd naively assumed that perhaps it wouldn't do that when it's in the screen-off state. Unless you've asked for notification other than on the top bar, of course?

To be fair, the phone doesn't know when you're going to asleep now does it? (especially if you're a night worker).
I notice that there's an application in the market now which can automatically turn airplane mode on according to a schedule, so that may help but of course this does mean you won't get phone calls!

Dave

No it doesn't but I'm developing a widget which will disable data access at certain times (dependent on user) so overnight it wont use data and save battery.

Right; I really meant the following, but worded it wrongly...
I had expected apps not to do data access when the phone's screen is off, unless they have been configured to notify via sound, vibrate or light.
i.e. if an app either isn't notifying, or is only notifying via the top bar, then it should disable its data access when the screen is off.
That would mean a short delay in getting updates, when the screen is back on, but I'd rather have that than spending much battery time pointless checking for updates when I'm not going to see them for ages, whether that's at night or just when the phone is sitting on the desk for hours.

aha! that sounds great, thanks in advance
would you update us here when you have something testable, please?
and if it's not pushing my luck to ask: any chance that it might also have a manual switch too, for those of us who go to bed at wildly different times?
Or perhaps there is already a way to disable data access manually, with a single setting change, without disabling the phone? I think there might be...

ah yes indeed, there's even an HTC widget to disable mobile networking, whilst leaving phone enabled. That will do for now

I have figured out the solution to the battery problem many of us have with Froyo

- Update to AOSP Email.
- If you are using Exchange, use Push only. Do not use the interval syncs.
- Uninstall / Disable Juice Defender
- Uninstall / Disable ATK
The whole problem is wake locks. The current Email client has an issue with wake locks if you use Exchange ActiveSync and do not have Push selected.
As well, if you have ATK installed, and it kills Email, then when it starts up again it will enter another wakelock.
Juice Defender causes the same problem by disabling the radio - basically, Juice defender makes the battery use worse, not better, because the re-sync of the email every 5 minutes makes it go into wakelock mode and never let go of the CPU.
After fussing with upteen dozen kernels and roms and modems, making these 3 changes has had a REMARKABLE decrease in battery use. I am burning my battery at less than 1/2 the rate I was previously.. I now burn less than 3%-4% / hour. Which means I will easily get through a full day with the phone.
EDIT: The other thing to make sure of is that you don't have the buggy version of Gallery3D that drains your battery due to holding onto the sensor. Your best bet is to just totally delete the APK from your ROM, and install the one from the market if it is an app you want.

Title is a bit misleading, please add problem with email battery drain, because a lot fo the froyo drain issues is for people not using the email and not even connected to data network mode.

You said update to AOSP mail ... anything wrong with the stock Email.apk?

Here's something i discovered, but wouldn't mind confirmation from others.
When waking your phone (with the charger not connected), is there a one second delay for the screen to come on? If there is, the phone is sleeping fine. If not, and the screen wakes instantly, something is preventing the phone from sleeping properly, thus wasting battery..

Its not really a good second but yeah there is a delay, never noticed it was instant.

As far as I can determine both AOSP and stock email APK have this issue, it hasn't been fixed in source yet. But, I have switched to AOSP so I can only report on results when doing that.

You don't have to be connected to data network. In fact that can be the cause of the whole problem!
If you use email and either
- It gets killed
- you lose network access or it is turned off (a-la Juice Defender)
.. then it goes into this wake-lock state and hangs onto the CPU forever, draining the battery.
Every person I have seen complain about the excessive battery drain was using Email like me.. the most common comments are along the lines of "all I have going is email and..." so I suspect this (along with the Gallery3D issue) is the cause of most everyone's problems.

so if I'm not using the Email app at all (I removed it entirely)
it SHOULDN'T be munching through my mAh?

You don't have to uninstall juice defender. Simply adjusting settings so that it does not force a sync on schedule. Then it actually saves battery again.

I don't have any battery drain (Doc's 7.6.2 JPO).
I use stock gmail app 'cause I only use three gmail accounts with data sync enabled.
I never installed Juice Defender nor ATK...
My battery lasts 2 days.

No, just turning the radio on and off causes the Email app to lose connectivity and go into the wake lock.
Update - my phone burned through only 8% overnight from 11 PM-7 AM. Previously it would burn through 40%+ overnight, no matter what kernel or modem or other options I turned on or off.

Did you roll back the Gallery app?
Also it is possible you have another app with this wake lock problem. Run Spare Parts, Battery History, and change the dropdown to since last boot/Last charge and "Partial Wake Use". Click on whatever 1 or two apps are on top.
If the time listed is more than a small % of the time since last boot or charge, then that app has a wake lock problem.
In the case of the Email app it will easily have a wake lock use time of nearly half of the time since last boot.
Any app with a wake lock is a huge battery consumer since your phone never goes to sleep mode.

I'm not having any major batteries actually ;p I mean, if I can somehow improve battery life by changing some more stuff, why not?
I'm on the Gallery off Market (no sensor issue). on another thread if users are reporting Stock Gallery not having any battery drainage, I might roll back to try it out.

I am sorry for noobness, but how do I do these things you suggested? I cant find this configuration to disable checking mail besides push.
I am using stock email app and my gallery doest have sensors problem. But my cell is draining like 20% overnight (6 hours while cell was sleeping). This is insane and I cant track what is using this much.
PS: I am using Doc rom with cfroot

Open email, go into Account Settings. Under Check Frequency, make sure it is set to AUtomatic / Push. Then make sure you don't have any auto task killers or other things running that kill apps or turn your radio on and off.

I think email is the problem...

automatic/push selection

forgive my noob question but I cant find automatic/push in my email settings at all (it only allows for never, or other time intervals up to an hour). This is on the AOSP email app.

OK I should have mentioned Push is applicable to outlook email only. If you are using some other POP email you can't use push. I am not sure if Push is applicable to IMAP.

using email and settings switch to "Never"
did not seem to encounter this b4.
My data is usually turn off. I only turn on manually when i need to check mails or surf net.

I dont have sensors issue with gallery and I have removed all email programs from my SGS.
Still have battery issues. It drains really fast when data is on and I cant track what is using so much power

We need a stickied battery improvement thread

I am happy to make one.

My battery tips
1. Latitude : If you are logged in, it will update your location every few minutes. This will make a phone that should be on a very low power state, re-enable lots of things that suck power. (5hrs)
2. Home screen weather clocks : Just change the update interval to something more like every 3 hours and it won't kill your battery as quick. Make sure you don't have it use GPS for location. If you don't mind, set the location to be static. (1hr)
3. Chat programs that don't rely on push. If the program needs to keep your data connection alive, it will kill your battery.(1-5hrs)
4. Anything that will update automatically. The craigslist app for example will poll the site for changes, waking the connection and the processor each time.(1-5hrs)
5. Bluetooth. : I know it isn't an app, but if you aren't using it, don't have it on. It takes enough power to eat a few hours of battery life. Pretty major. (3hrs)
6. Leave 4G on. : This might not work for everyone, but when 4G is asleep, it doesn't seem to suck juice the same way 3G does. My EVO dies quick on 4G, my Epic battery lasts longer on 4G. (as long as you are in a 4G area). (3hrs)
Disable these things and you should get battery life that you hear others bragging about.

"Latitude" on my phone and others I've seen, does not update that often and really only constantly updates is when you have maps open. My wife and I both run latitude and have not noticed anymore of a battery drain than not running it.

Mine updates every few minutes on WM and Android. Turn on your history and you will see it updates hundreds of times a day. After my froyo update, I couldn't make it through the day. You might have location set to wifi or wireless, I probably should do that too, but I'd rather keep it active.

I subscribed to it.

i thought the whole idea of push was that it doesn't use data cause its a server side push instead of the phone polling at a set schedule

Weird, I have history on and the setting to update automatically, and still only updates only once every few hours on it's own. Maybe mine is "broken", but glad it is then. I'm on an htc Incredible.

If you are getting excessive drain while on wifi, check for unusual traffic on your network as the problem is probably not your phone and something else polling your device keeping it awake.

For me, the problem was HP's wireless printer software on one of my laptops.

I'm wondering if one of these 2 is a big sleep preventer:
1. "Background Data" (I used to think all you had to do was disable "Auto Sync" but when I uncheck "Background Data" I get a popup saying something about how I will save battery power if I agree to disable)
2. "Use Wireless Networks" (even if GPS is off).
I usually have been getting good results after unchecking a combo or both of these and sometimes I even have to reboot to get back to normal Epic sleep.

Would limiting background processes through developer options save battery?

I have read a lot online and there seem to be a lot of different information about the developer option and limiting background processes. From what I understand, even if I set it to none, I will still receive messages via GCM from apps like Facebook Messenger.
But apps would refresh every time I open them, so more drain when multitasking, but if I mainly use 3 apps, it shouldn't refresh much by setting it to three?
Even of I set it to none, my standby time would increase, but my battery life when using the phone would decrease, right? Because of the continuous reload.
So is my understanding right and do you know if it actually saves power? Also, as stated, if I use very few apps daily, would it increase battery life limiting background processes to a low number?
Thanks in advance

things that might help save Battery :
disable Facebook app & other apps you don't use/need
turn off location when not in use
turn off NFC when not in use
when on WiFi turn off Mobile Data
turn off Bluetooth and WiFi scanning (to stop apps scanning in the background, apps scan even when Bluetooth & WiFi are Off)
turn off Nearby Device Scanning

I don't know what that have to do with anything.

If you are already using 3 apps only, there is nothing more to be kept in ram, so if you limit to 3 the number of the apps that the phone canzoni keep in ram, nothing will change...
