Battery drains 50% a day...whilst idling!

Guys,
pretty much as the topic says...it drains about 40 to 50% a day when it is idle....if I am using it it can be anything up to a 1% a minute.
Any hints on where to look - tried using battlog to log the usage but i cannot open the subsequent file at all.

Wiggz,
Try checking if you're in a dead-zone with no reception? (Your phone may be constantly trying to search for a signal). Do this for Wi-Fi too. Make sure it is not constantly scanning for a network.
Similarly, open up your task manager. How many programs do you see running in the background? Remember that pressing X in Windows Mobile does not mean it closes the application, it only means that the application is minimized.
Cheers.

Wifi is hardly ever on. My signal is always constant, but I have my data connection on 24/7 for emails. The only program I ever see consume CPU power when idle is "changescreen". I always check that a program has closed properly when I click the 'x'.
I know data connection on eats some battery but jesus - not that much surely?

Wiggz,
The question remains, how many programs do you see when you open up the task-manager? You did not answer the question.
From what I've observed with my friend's Toshiba Portege, he lost 30% in an hour. He did not realize that he had 15-ish programs "idling" in the background with very little RAM use. Long story short: Turn everything off if you don't need it and just keep the Task Manager running. He now goes through the night with 1 ~ 2% loss.
Good day.

When I open up task manager I see 4 applications running (taskmgr, manila, cprog x2) - when I check the processes I have many more obviously. However these are all processes I'd expect to be running (gwes.exe, cprog.exe, device.exe, services.exe etc...)
Any more advice?

Wiggz,
Unfortunately, that's all from me (I dont even have this phone yet, I'm saving up for it in the next couple of weeks). Try turning off your data and see how it goes. But damn, 50% loss just on idling, something in the background is definitely killing the battery.
Cheers!

Thanks for the help anyway - annoying the crap out of me. My Artemis used to go for days without needing a charge...I suppose my battery could be screwed but I want to troubleshoot first before I bite the bullet on that one - suppose I could hard reset and see what the drain is?

Things idling in RAM should not have any significant hit on the battery life. However, having the data connection on 24/7 will indeed kill your battery life, especially if you're using 3g or higher (Edge drains alot aswell, but not as much as 3g and higher). Since emails seem important to you, I'm guessing you have it set to dl every 5min (which is the most frequent setting). If applicable, change it to 10 or 15; granted it's possible you do need to get your emails ASAP and you need the 5min frequency. Now regardless whether you changed the frequency of the auto dl or not, set your data connection to terminate after a 1min of not being used. This should help you get a good bit more out of your battery.
(I have emails dl every 30min and RSS feeds and push pages once an hour. Data enables itself when needed and then terminates after a minute of not being used. This allows me to get much more than a days usage out of the phone. The only way I kill the phone is if on top of all that, I listen to music/radio for about 6 hours)
Hope it helps
oh, and in case you don't know, HD Tweak is one way to terminate data after X amount of time of not being used.

do you have stock or cooked rom btw? duttys v3 xt, for example, is known to drain battery a lot.

Cheers for this. I have HD Tweak and have tried that data connection termination setting before, however there is a little comment along with it that it can stop data and/or voice calls. Has anyone had any issues with it?
Thanks

i had similar problem, battery got drained overnight or during the day with a speed of light... but in my case the bad boy was Palringo (IM) which was auto starting with every phone reset and did not show on taskbar...it is so bad that it drained fully charged battery in aprox. 6-7 hours. so now i hardly use it, and whenever i do i make sure its closed properly....

personally I have had no issues whatsoever. The voice calls that I'm guessing they're referring to is VOIP which uses your data plan to make the call as I don't see why it would interfere with normal calls. I think the easiest thing is just to give it a try, and if it doesn't work for you, then let us know and hopefully we'll be able to come up with a different solution.

Well the reason I mentioned it was that I enabled that as one of a number of weaks and ended up having to hard reset as I wasn't getting Texts in a timely manner etc....it was probably another setting but I couldn't be sure.
Will try again. Only other thing is that data connection on 24/7 is great for a quick browse here and there and stock updates etc...

why is that, by the way?

You haven't got Sprite Virtual Mobile installed have you? I tried it out on my HD and it sucked the life out of it for some strange reason. And it wasn't even showing up in task manager.

Is there a list of processes, services etc that we can safely remove/disable to work in the background? What say all?

glad this thread came up - my blackstone has been absolutely fine until I had the genius idea of "optimising" everything about 2 weeks ago with HD Tweak...
Now it's not HD Tweaks fault, but whatever I have changed means that it can drain a full charge overnight, and by morning its nigh on empty, i'm going to try and change it all back today, but for sure some setting I've changed is sucking juice like no-ones business.
FWIW - I havent installed anything during this time, the only thing i've changed is some of the settings - so it's not a "rogue" app draining the battery.
OT - sorry for the semi-hijack - I guess my point is that i'll have a play with the settings and see if I can determine what's eating the battery and then compare with other people.

that's fine (re: hijack) I think the two topics are closely connected.....not sure of the answer though

ta - me either - i've changed a few settings and made a note - will post if it doesnt eat the battery overnight over the next couple of days.

I think Ive found the cause to the battery Drain....

Ive been working away with Artemis Ver 9.0 and Radio 2.09. The battery has been superb e.g 3 days worth. The other day I setup Windows Live and my battery drain within 10 hours of very very light useage. I was not ever sign in to messenger but hotmail must of been checking for new emails. So I got back home and logged out of live and disabled my hotmail. Now my phone has its battery life back. I cant put it down to anything else because I had full signal and nothing else running.
Also this fixed my problem with the front screen crashing.
What do you think?

Not sure if you know, but you can change the frequency and time span in which your email is checked. I'd set it to check during a specific period throughout the day, and only every hour or so, depending on your needs.

I made sure hotmail was set to manual but that didnt do anything. I think there might be some sort of bug

I'll have to agree. with windows live active, sync set to manual, battery life was terrible.. without windows live, battery life is much better.

from 9 last night its gone down to 90%! ive used the phone alot for txting. Everyone try it whos having a problem

[Q] Basic phone (long battery life)

Hi
I've been reading xda threads for long now and I have always wondered if there was a way to transform a smartphone into a basic phone. Let me explain myself.
I own an HTC HD2 and I'm really satisfied with it's big screen, power, ... I live in a house with electricity cool and thus charging it every 1 or 2 days is not a real problem. But once a while I have to live a fews days or a week without electricity (for example holidays like a one week camping), but I still have to receive a few important phone calls.
I'm using Android right now and this led me to think of a linux build (for example launched from WM) that would only enable us to browse our contacts directory and manage phone calls. The interface would be very simple, without beautiful effects, and I guess it would be possible for the battery to last very long this way, since most of the apps launched on powerful OS would not even be included. There would be not slidings, no transparency, and everything that require power.
I'm sorry if such a topic exists but I took some time to search and nothing appeared. And please don't replay "It is not the purpose of smartphones" since I know that, I've made a choice and I'm satisfied, but I just want to know if there's a way to make it even better.
I'm not (yet?) a developer so what I ask might be unrealistic, but I'm convinced this idea could be useful to most people. There could also be other ways to achieve this, like another OS or just a WM mode...
Don't you think it would be great to be able to switch to this when long battery life is needed ?

Hello,
That is actually quite interesting, but the first time I have heard of such a query in the 9 months this phone has been released.
Just out of interest, have you tried running the phone with just the standard WM interface to see how long the battery lasts?

Alternative solutions:
1 - You could always try wind-up, or solar charger.
2 - buy the cheapest PAYG phone you can get (on your network)and put your HD2 SIM in it.. These tend to last quite a few days on standby and you don't really care if it gets bashed or wet.

Morpheus, what you mean is WM without sense ? I'm not sure there would be a huge improvement...

you can turn Sense off in Settings/More/Today,
and according to BattClock power consumption on my Leo (YMMV) is:
Sense: 100-300 mA
Windows Default: 42 mA

Turning off sense would give you a noticable amount of battery life......
The sense interface is a hungry hungry beast........
The linux idea is nice but the problem is that it would be running on top of windows and therefore not save any battery.........
Luckily I still have my trusty (4 days without a charge) N95........
The old girl still comes in handy...

Whenever I break my good phone I just use a T-mobile PAYG phone until I can order a new phone. Or if I'm going camping or biking or something.

nice i will try to disable sense ! thanks for this tip
about linux, i believe i read that wm is completzly shut down when launching android (it only serves as a trigger ?)

Running SPB Mobile Shell, I lose 1% of battery life every 3 hours on standy. That's with data and wifi turned off and just the phone running. That would give me about 300 hours of standby time. In theory that should last you a week with a few short calls.
Problem with Android/Ubuntu on this phone right now is you have to run it off the sd card, which draws a lot more power. Whenever the screen is on it draws a lot of power anyway. The best I've done so far is 6% drain over 8 hours with just the phone running in standby.
The most obvious/best solution for you is to just bring an old dumb phone instead or as backup. Then you can just slip the sim card out and use that to make/receive calls.

[Q] Battery use always exceeds 200mA and wifi tethering doesnt work.

Hello, I have been installing android builds on my HD2 for months now, and have to say the recent development has really left me with a great android phone.
One problem I find I have consistently is that I can never get the kind of battery usage others speak of. Mine trends at 350mA right now which seems wrong cause my battery life isnt THAT bad. and I have never had a build thats had better than 10%->hour.
I'm using ShubCRAFT 2.0 with the hastarian r8 kernel, chunkydroid ROM and 02.12 something radio, i also have an australian HD2.
I keep my screen quite dim, wifi and bluetooth off, no over or underclock (since r8 doesnt support it), no auto task killer.
And while I'm at it my wifi tethering should work based on my build and kernel but every time i check it it says "Error" and third party apps are a no go either.
Any insight would be greatly appreciated.
Also to all the devs, I love you, I want to carry your children.

i always make setcpu, max 619mhz min 254, screen off: max & min 254, auto task killer when screen off and i disable all auto sync, like facebook gmail etc.... im getting acceptable result, around 2 days with normal use

I had just finished reading that list and forgot to try the 3sec. boot which helped. I'm at 10mA now it makes no mention of the wifi tethering problem, any idea on the subject??
EDIT: It flew back up to 200+ after 5 minutes and hasnt gone back down since.

Battery dying very quickly - what to do?

My Evo battery is draining at a rate that is all together too fast. I took it off the charger about 3.5 hours ago and it has drained about 30-40%. I have not made a call nor used the net at all save for the receipt of 3-4 emails. I had a rooted phone but I reset the phone back to complete unrooted stock. I have not even so much as installed an app. What can I do about this?

turn off your mobile data when not in use. This will save tremendous amounts of battery.

if you search the forums you should find countless threads on battery and how to find out what is draining your battery and to extend life.
not sure why you would unroot unless you were exchanging it at sprint store but it greatly limits what you can do to help prevent battery drain. If you dont want to mess with much jsut use a rooted stock rom and it is pretty much the same thing as being unrooted but you keep the extra rooted benefits.
your best bet on non rooted device make sure mobile data, 4g, auto orientation, bluetooth etc are turned off. do the HTC battery condition/charge trick. and turn off background sync.
my suggestion is to re root and look into undervolted kernels and many other battery saving tricks found using search!
hopefully it helps some.

I had the same problem OP.
Turns out my radios weren't update.
Head over to the developer section and download the newest radios and stuff.

I've seen significant improvement of my battery life by using Collin_ph Battery Tweak 1 that was offered by Myn's when I flashed his/her's rom. I had my BF take his Evo to work after he come home complaining that the charge would only last about an hour or two and behold, he got through the whole day without having to charge his battery. This is after listening to music at work for 8 hours also. I HIGHLY recommend this tweak for ROOTED PHONES as I and everyone else I've recommended loves their Evo now and have no complaints...I'm at work right now and I'm at 79% and when I usually get home the battery is either still green (full) or orange (med) charge. I'm not sure if this tweak can be used with other mods but I'm very happy with this tweak as it has made my phone perfect now~~

Could be a Rogue app running killing your battery or radios not updated like stated above.

I recently started having the same issue. Advice such as turning of data and the GPS aren't helpful since the device functioned fine with GPS and data on before. Also if the battery was draining at a slower rate on the current radio before, you shouldn't need to update it, should you?
Seems that either something is making the Evo use more juice than it was before or that the battery is not holding the same capacity it used to. For some reason Phone Idle and Cell Standby have been using quite a bit more juice than they used to.
I don't like some of the software mentioned to try and locate anything that could be using more juice since those programs seem to use quite a bit themselves. Either way, what could be doing it that would come up as Phone Idle or Cell Standby in the included battery monitor? Wouldn't anything else come up under Android System?
The battery draining that quickly is not normal even with background sync, GPS (idle), 4g, data, or anything else on. There is another issue which must be solved. To troubleshoot so far I've tried another battery (same thing happens) and now I'm trying with everything turned off. If I can isolate what was causing my sudden rapid battery drain, I'll update everyone. This just started a couple nights ago for me. I think I'm on the latest radio, but I'll check.

Last post sums up my problem perfectly. I have an extended battery that lasts half the time it has over the last 4 months. Started with the radio updates. running myk

Use the battery usage functions of 'spareparts' to determine what's consuming cpu or preventing the phone from sleeping.
Can't fix the problem until you've isolated what's at fault.
Turning off mobile data will indeed fix a problem of some app trying to access the network, but it won't solve the actual cause.

I think juice defender does this automatically when the screen is off.

In the case of my phone, and I believe the OP's, we don't have any rogue apps or things running in the background. I know this phone like the back of my hand. I have completely uninstalled unnecessary apps like facebook, twitter, all things like news and weather are on manual update, i don't keep 4g or gps on, and I use wifi at home. I turn off 3g in terrible reception areas. I'm not a new user who doesn't understand the basic ways to save a little battery. I'm pretty sure the OP isn't either by his post. I use my phone the same every day. My chinese extended battery would last me easily from morning to bedtime with 20 to 30 percent to spare. Now I can't get near that after the radio updates. Since it's been well known that something is weird with these current updates, I've downgraded to 1.77 to see if that helps. My phone was sleeping fine though, so I don't know how much it will help. Always some BS with this phone.

I appreciate it. I really do. But that is exactly the things I'm saying are already off. GTalk is turned off immediately on my phone from the jump and latitude has never been opened. It's got to be radios. I guess I'm not really asking a question, I'm just telling the OP he isn't alone.

this is the thread with flashable .zips of alllll the radio updates ever out for the EVO.
http://forum.xda-developers.com/showthread.php?t=715485&highlight=radio
if you are having trouble after a radio update, just try some of these other radios and see if that helps

Your best bet would be to root your phone again and give one of the SBC kernels a shot. I'm running CM 6.1.2 along with Zendroid 1.1.0 BFS AVS SBC and I can easily get 16+ hours with HEAVY use. And when I say heavy use, I mean hundreds of sms, dozens of calls and lots of websurfing. You will love the SBC kernels. Give it a try.
PS. My name is HondaCop and I approve this message.

We can offer suggestions until we're blue in the face.
First off, the OP needs to provide specifics of what's installed on the device, including rom, kernel, radio, etc, not to mention the hardware version itself.
Assuming it's not the known pri /rom conflict, then determination needs to be made as to what's actually consuming cpu - see first sentence above.
Need to use a systematic approach to troubleshoot this, otherwise it's a waste of time.

That sounds like a very weak cellular signal is forcing the radio to keep searching for it, draining the battery very quickly.
One way to somewhat alleviate this problem is to force roaming, to connect to a provider with a better signal.
"Roam Control" app does this (Market).

Actually,
some android users looked at the posting date, saw that the op hasn't updated in over 24 hours, wanted to complain about it, decided against it, posted quickly the most useful idea they had.
All that while doing real science.
