For the first few weeks I had my HD the battery life was brilliant. With minor use it'd have high levels like 95+% when I go to bed at night, but the last week or two something has begun really guzzling power from it and I can't figure out what.
I don't think I installed anything new, so I want to find out if there is a way I can easily identify where the power is getting drained so badly. For instance, some days now it is down to about 55% by the middle of the day without even making a call or using any data services etc. I have bluetooth & wifi switched off all the time too!
Is there an app that can identify battery drain in a similar sort of way to cpu/memory use? Or does it normally follow that something using more memory/cpu will be the cause?
Thanks guys!

Try the following task manager and click on CPU Usage at the top. This should help isolate what programs are active
Thanks very much for the reply.
I did look in a task manager I already had and I found that Phonex seemed to be varying but generally using up to 10% cpu just sitting in the background so I have uninstalled it (shame - it's nice).
I'll add in the task manager you've given me and check that, and see how it behaves now PhonEx is gone.....

Here's an update - I couldn't find anything else that was really using any cpu, and the main culprits using memory seem to be important stuff (I think - shell32.exe & device.exe & cprog.exe) so I doubt I can do anything about them.
Anyway, it wasn't bad last night after removing PhonEx but this morning it had used 10% battery in half an hour without even being used at all!!!
Rebooted and it's stayed on the same battery level now for over an hour but I don't trust it - it seems very erratic and I'm really not sure the best way to find the cause still.
I'd do a hard reset but it'll be a right PITA to get everything back on it again afterwards.

I would recommend reading this thread
A number of ideas have been given including using SQTools to identify what is using up the battery.
Good luck and keep me informed
Thanks for the reply again.
Are SKtools/SQtools two different things, or is that just a typo?
Have already got SKtools installed so I'll give it some scrutiny. It's obviously behaving at present though as it's an hour since my earlier post and still on the same battery % level.
Thanks for the link to the other thread anyway. I'll obviously be keeping a close eye on this so I'll advise any findings as they come up.
I've never known anything like it with this battery - no regular pattern sometimes brilliant sometimes awful. Very sensitive to chargers and type - one person reported here that if he charged through usb on computer his battery life went down really quickly afterwards. If he charged through mains battery life was much better. I also just found my charger on my motorbike has a small amount of rust/dirt in it and is causing the device to discharge.
I am not helping but just reaffirming your findings. I did find a programme called BattLog useful to see what programmes were causing high level battery usage. I don't have the link but you can find it here somewhere using search. Another tool for your collection.
Good luck!
Battlog eh? Thanks for the suggestion - will look it up
*edit* here it is - I'll try this tonight, if only as it's quicker than going through the SKtools menus to get to the power usage:
http://www.freewarepocketpc.net/ppc-download-battlog.html
I just began uninstalling stuff to see if it helps (seems to currently run around 106-111mah drain - no idea what might be considered 'normal' and have seen other posts questioning this but no real answers - yet).
Uninstalled Memmaid, and the wedge 18 tab action screen, and also Singh's 15 tab thingy. Have also turned off Handy Switcher as I had that running from startup. It's still drawing 106mah after all that!
One side effect though after removing those, was the weather applet appeared on S2U2 when I unlocked it - first time it's worked! It did disappear again though so there's still a problem with that too.
I've seen many posts where people blame software they have installed and the developer denies it is the software etc.... I think in the end it comes down to the device/battery or manila/TF3D. I may be wrong of course and will be interested to see how you go with it all.
I think it must be software since I have a lot on there and it was fine for the first few weeks I owned it and then suddenly began losing LOADS of power.
For some reason my data connection is not working now either! Might be time for a hard reset I guess.
If you are getting ~150mah consumption when the unit is in use, then with a standard 1350mah battery the lifetime should be 9 hours per charge.
If your battery dies in 1 day, then the unit is consuming the same amount of power almost all the time, even when it's locked or sleeping and this is not normal, unless you want it this way.
Some software, in particular lock managers and button managers are believed to be causing battery drain as they prevent the device from entering deeper sleep states where power can be conserved.
There's software floating on this forum that enables wi-fi and wave audio drivers to remain active in unattended mode (when your backlight is off) too, battery is drained a lot faster when any of these are installed.
Good points
I doubt there's any way of monitoring what power is being used in standby mode is there?
For instance, would an app be possible so that when sync'd and usb charging turned off the app on your desktop could run the same power monitoring process that you find in the likes of SKtools? That would answer a lot of questions I think!
PowerGuard
I used PowerGuard, when I was troubleshooting my battery problems ... and you can run the monitor and put it in standby mode, backlight off etc. I used to consume ~180maH when on, no calls no bluetooth and ~96mAh when backlight off/standby.
For me the culprits were S2U2 and Enable HSDPA in the phone settings. I cant get 3G cause im in the US, but it was alwys searching for a signal... after disabling those two.. im at 115mAH when on and 33mAh when standby and back to an ~18 hour battery life.
Oh dear, I just made a new thread with the same question really Silly me.
What version of S2U2 are you using? Did you upgrade that recently? I moved up to 1.5 and I think that might be the culprit, but I've uninstalled it and still having poor battery problems.
**EDIT** Okay, so I have Battlog installed, the drain sometimes shows as -330ma, but how do I see what is causing that drain?
My battery was lasting 2 days on the standard rom, using S2U2 and with HSDPA enabled.
I then upgraded to the Davideuck V-1 HP, and changed the radio from 1.09 to 1.12. Again I did have SU2U installed.
The battery then lasted about 6 hours, and the unit shut down before the ending of my day at work. I can only assume that the pda was consuming too much power even when switched off.
After two frustrating days, I gave up last night, and installed Davideuck V6 and changed the radio to 1.10, and now the pda battery is lasting for ages. It's only dropped from 100% to 99% after 5 hours.
OK, I know I should have changed things one step at a time, but I must assume that either the 1.12 radio or the V-1 rom is causing the problem.
I don't think S2U2 is the culprit here. But I do suspect that it might be the V-1 rom, as I believe that some folk have a similar problem with the new Dutty rom too. However, other users of the V-1 rom assure me that they don't have such a problem, so I'm confused!
Hmm, Dutty's 2.0 is using radio 1.09. Maybe I should try 1.10? Where can I get it from?

There should be for example "Active Application=ThumbcalStart" just above the temp/ma figures in the log file like in this screen shot post 17.
I am guessing 330ma does not sound too excessive for an open application as long as it is not running all the time.
So, idle it's at around 90-100. When I turned it off and S2U2 didn't start, it dropped down to 33 fairly steady. When I locked S2U2 and then turned it off, it stayed around 80, dropped to 50 for a little while and then came back up to 99...
I don't even know why did I update, 1.43 worked fine for me. After I installed 1.48, I've noticed several problems:
- battery drains a lot faster
- problem with the auto lock, or lock with "end" button - after I want to use the device again, it won't turn on all the time, buttons glow, but nothing happens
- few times phone didn't wanna dial some people when I enter their contact and try to dial their numbers
Anyone experiencing similar issues? Both versions of ROM (1.43 and 1.48 are WWE East Europe)
can't be that I am the only one facing these problems in 1.48
hehehe seems u are tryed to flash 1.48 a second time?
I seem to be having a problem at the moment with 1.48 where sometimes (usually) if I plug in my phone to the computer it freezes up. Only way to solve it is to take the battery out.
Don't know if it's to do with 1.48 or some other program I've installed. Doesn't seem to do it all the time but it really p!ssing me off. That battery cover isn't easy to get on and off. Why on earth didn't they put a small reset button somewhere like on my trusty Trinity.

I reverted to 1.43 WWE East Europe, downloaded from HTCPedia, but seems like battery is again draining a lot faster than on my stock ROM. I don't know what whas the catch in my stock ROM, the one I got when I bought the phone, but seems like battery was far best on it.
It was 1.43 WWE East Europe as well btw, I have no clues..
the problem with battery is with htc sense. You can notice this disabling it for a day and using the Windows default. It is a huge diference
Im using 1.48 official and not get any special problem....
Yes, sometimes after reboot my device I not get lock of screen. But if to do long press of OFF button and choise LOCK then all works fine. Also, I have problem with Skype, but it not special problem, I think.
Battery works about 1-2 day with my style of using device. It mean 1-2 hour of speech, WiFi when available, Inernet browesing and checking mail every 10min. I think, this normal.
With 1.48 I have more faster connect to WiFi, more stable connect in GSM and more natural sound.
May be, I will reflash my device to 1.43, but now Im happy from 1.48.
i have the same battery drain with 1.48,
back to 1.43
I have similar problems. 1.43 was working great for me and I thought I could get a little more out of my HD2 with 1.48. Turns out not. Battery life has decreased, the phone crashes every now and then (as opposed to never with 1.43) and the camera takes horrid pictures with the flash. I am thinking of reverting back to 1.43. I am using the Western Europe ROM.
I will now wait for official HTC roms before installing anything.
Sure you can disable Sense and have huge battery life but that sort of defeats the purpose of the HD2 in my opinion.
Bear in mind that WM seems to take a little time to 'calibrate' the battery with each new ROM. Various threads I have read suggest anything from 2-3, up to 10 or more battery drain/recharge cycles before you get a true reading.
Ditching a new ROM after only a day or two may therefore be a little previous...

Strange with 1.48 I can take really great photos which I couldn't with 1.43. My phone since I have flashed it to 1.48 never hang/crash but battery drains very fast.

I had also read something like that regarding the battery and new roms.
example for Energy ROMs
BATTERY SAVING TIPS
The first few days
• There is nothing special about this ROM to make it use more power than other ROMs except that it is tweaked for performance over battery life. After things have settled down, you should get a couple of days usage out of a charge.
• Immediately after flashing, you will probably observe very poor battery performance. This is due to the charging circuit having to reset itself.
• The battery meter will not settle down and give accurate readings for a few battery cycles. Give it a few days.
• For the first few battery charging cycles, try to charge to 100% with phone off and then allow battery to drain down quite a bit before recharging. This is so the meter will calculate drain well.

Battery drain & other issues
I am not having iszues with 1.48. battery drain.
I heard this so often in the HD forum but never experienced it, and I was flashing Miri's roms every second day.
If people mean their battery runs down very quickly after a flash, well it takes a lot of power to reboot, and then you are probably going to run the device for a while to get all your settings back. Well this I have experienced, but next charge, no problems. I flashed yesterday and recharged overnight and after a day of use my phone had 50% left. No issues yet either.

Was about to agree with you when i noticed something today: i usually charge my phone overnight (it doesn.t matter how much battery i have i just do it to be sure) but few nights i left it without a charge and notice 3% to 4% battery drain overnight (1.43 rom). After update(1.48) i left it overnight and noticed 11-12% battery drain(even though i left my phone for a few days to get used to the new rom). Don.t want to jump to conclusions yet but there could be something about battery drain in the new ROM.
Hi
Battery problem, keeps draining quickly, just by leaving it anywhere. I charge the htc hd2, after not much use... the battery looses charge? I have s2u2 installed any ideas why this would be?
In other words, battery is on 100%. I open it using s2u2 and close it, just random play aroung with the phone. Next minute you know the battery is going lower and lower in matter of minutes. Thats with no phone calls, few text, no music, no games played i think your getting the gist?
This is wierd? anyone else experience this?
Please can some help and advice in the right direction.
thanks.

hi pa49
I have looked at soo many post on xda, but i cannot get to to the bottom of it?
1. Is there any post you might note of, that could possibly put me in to the right direction?
2. also any place you can get extended battery (not the big fat one lol)

you may want to install battclock and check what0s your cpu usage, also disable s2u2, check differences, and whatnot... the only way you can find if it's a software problem or not is by checking with a clean rom.
Usual old boring advice, backup and hard reset, test with nothing installed, if there is the same problem of very high drainage, it's basically a good chance you need to send it back for warranty
I have exactly the same problem. Suddenly yesterday my phone's battery drained and I found my phone switched off, out of nowhere. I charged it for 3-4 hours, and then played some games, the battery was left at 85% and when I woke up today, after 6 hours, it was off again.
So you are suggesting to perform a hard reset and observe the way the battery drains?
Ok, First get the battery working at max capacity by charging it non stop for at least 2 weeks. Whenever you can and wherever you can for as long as you can.
Once you have done that there is a battery monitoring capability built into the charging circuits. You could then allow your battery to drain to cuttoff and then recharge to full again which will accurise the power remaing readout. I never bother with this step as I just use the phone and then recharge as soon as I can again, but, if it's important to you then go ahead, but, don't continually allow the cutoff point to be reached as this will damage the battery.
Now you have maximised the capacity of the battery see how it performs and assess whether you need to take further action.
Installing apps to mem card will eat battery.
Some say leaving apps open will drain the battery. I'm not too sure, but, it's good practice to close them any way.
Finding a clean and pared down cooked ROM will save a lot of power, but, you will have to do your own experimenting there.
After that you could invest in a spare/extended battery, however, I would suggest an external rechargable power pack (Have a look at the juice bar solar pack as it will recharge itself without needing a power socket or USB port (although you can use them!), purely by sunlight. Another advantage is that if you change your phone you still can use the pack with your next device and they will also charge many other devices!
Good luck!
I have my new hd2 leo, and battery seemed to be the main issue for me cause it couldn hold 1working day... but as everybody told its nessesery to charge 1 week to exercise battery for its full potential.. but i did some improvements, did the registry thing with dissablepowersavings dont remmember where found that, and instaled wmpowersaving, for control of 3g 2g data, using 2.12 radio rom, witch is more stable than 2.08 cause i use hd2 for a lot of browsing, and 2.08 was freezing my device.. 2.12 is stable and seems using much less power, i can feel less heat in the back of the case.. tried android... but that was not intterested me... i dont need those 1000ds of apps i need to browse the internet using iris browser.. and now battery easily can hold 2 days with some wifi 3g browsing.. and few phone calls some usage of camera.. witch is poor in dark conditions... so i think battery life is 2days ... and control the 2g 3g networks, turn off location service, turn off data connection.. and the battery for today evening is still 72% after 10 hrs of few phonecalls and a bit browsing with wifi.. some gps navigation i dont even think to buy expanded batery cause i dont like the BACK BIG CASE ... Also i wonder how much power is nessesary to run Micro SD built in card reader... because its a pitty to have 180mb internal memory for progams... if it had 2gb then u install everything in the memory and dont use the sd card reader witch i suppose will save couple of hours of battery.
this issue has been well documented..imo the stock rom battery life is awful lasts up to 24hour on casual use for me..there are cooked roms with better battery life or you could invest in a bigger capacity battery from htc or third party ones on ebay
There is a known issue with the HD2 and microsd cards, when the microsd's filesystem becomes corrupted, causing battery drain.

Ok, so I did a quick test, I turned off the radio just to take that out of the equation.
I ran for two hours, first hour with SD card out and then an hour with it in.
From the log, you see that I am about 6 to 7 mA up until 0945 and then it started to cycle, I dont know why, the phone was in standby the whole time.
I put the SD card back in at 1016 and opened explorer just to access it once.
the cycling continued for like 30 min then settled back down to 6 to 9mA.
So, it looks like the currnt is a few mA higher with the SD card in, but I have no idea why the phone was sucking over 150mA in those four to five reading bursts when I was not using the phone.
What do you think?

Hi,
Ive recently installed Android 2.2 Froyo on an SD card on my HD2 and the battery is going down so quick... it wasnt great in Windows mobile but now I'm struggling to get it to last all day...
I'm saying to myself this cant be normal, I'm also trying a Samsung Galaxy S and the battery is so much better!!
Is there anyway I can improve the battery power on my HD2, I know in a HD2 the battery is a 1350mah and the Galaxy S is a 1500mah battery.
Should that make such a difference?
I'm considering going back to Win Mobile but dont really want to but havent got any other choice if the battery carrys on like this....
I also notice the screen and back get really quite warm... I suppose Android is making the system work harder?!?!?!
Its safe to say that you havent read any of the threads about battery life.
Before you say I did a search and didnt find anything Ive already typed in battery in search and found a bunch of threads.
Now what you need to do is find out why its running so warm.
It could be the kernal version you are using.
Ways to improve battery life are using setcpu and underclocking. A lot of members use current widget as a method to see when High drain is occuring.
In sleep mode you should be seeing less than 10ma. If you dont see less then this there is a problem.
Set current widget to 1 min intervals.
Dont use task killers they dont help anything no matter what anyone says.
Dont compare the captivate to the hd2. 2 different phones.
I am using mccm 1.5 customize, and CurrentWidget shows 5mA on standby which I think is good enough. Sometimes, it shows 60mA on standby in a while and my battery drains very fast, even I use Advanced Task Killer but it does not help. I have to reboot the phone to get it back to 5mA on standby.
Anyone has any idea of what may cause my standby power that high (60mA)?
Thanks.

Thanks for your tips for better battery life. I was curious about a few things and hope you could clarify a few things for me and some instruction or threads on how to do so. And yes I have searched, that's the first thing I always do before I do anything web based as far as positng.
1. How do you setcpu and underclocking?
2. How do you find the amount of battery that standby takes? i.e. 60mA? How do you get to that setting in android?
Thanks for your help in advance.
Setcpu is an app used to control your cpu speed.

To check ma's use (current widget)
http://forum.xda-developers.com/showthread.php?t=776085
long press on the desktop and apply current widget. It will ask you if you want to create a log. Create a log for 1 min intervals. Put the phone to sleep and leave it for a good 5 mins.
You can then open the log file usint astro file manager and check your drainage while sleep.
One thing I found is that If i am having high drain i turn my gps on and restart then it usually settles down and I can turn the gps off.
If you have apps that are syncing you will a higher than normal drain during those times the apps sync. if you set your apps to sync at longer intervals the amount of batter drain will be unnoticable.
I have major battery ocd. I constantly check my battery and have to force myself not to look but still use my phone as any normal person would.
I can pull more than 12 hours easy!
Thanks hazard99!
The first time I ran android I don't think I've had any battery issues and now that I'm looking at the percent on my homescreen Im beginning to feel battery OCD too. It's like I lose 1% atleast every 15 minutes when I look at my screen. But I did take and apply all the tips you told me and I do see that it only uses 5ma when screen is off. I truely don't understand. :/
Stop looking at your screen. Stop worrying. The more you look the more juice you use while the screen is on. There will be more points where the phone is off.

Thanks.

Ive also been trying to investigate this, my standby drain is usually 60+ mA, and during use it jumps to the 200's, strange stuff indeed....For you to have 5mA, lol i wish that was for me too =/

What radio and wm are you using? Do you use SetCPU?
I had high battery consumption, too. But now I found something interesting...
Due I'm not allowed to post links, yet, search for the post with topic:
[SOLUTION] Possible solution for heavy battery drainage.
With this fix: over night I only lost 20% instead of 59% of battery.
uninstall SetCPU

im using the same radio as you (2.10), energycookie rom 21916, and my setcpu is at interactive 245/729, and for sleep its at 245/384, hastarin kernal.
Use a Battdrv.dll from older HD2 ROM 1.48 Etc. I'm not sure if you recmod the module and replace the current one in Windows if you will get the same benefit as if you cooked the driver in.
i just updated my kernal to the latest zimage in mattc's froyosense's evo tree, and my standby is around 6-11 ma now, guess that solved some issues lol, anyone know whats the normal operating ma power consumption for texting?
EDIT: Now when i try to enable wifi i simply get "error", did i mess up on something? =/
EDIT: Solved above problem. WOOT!
Hi all,
Well the question is in the title I just don't get it why my phone on wp7 is empty
in 2 hours while android gives me 6.
I have to take my charcher anywhere I go.
And all useless "battery eating settings" are off.
Can i perhaps do more to increase battery life?

Hi there,
it is really not normal that your battery drains in 2 hours for WP7. It is also not normal that your battery drains in 6 hours for android.
Believe me, battery life is as good for android as for wp7.
I can do about 1.5 to 2 days with average use of bluetooth and with regular surfing on the mobiel internet.
What I did learn from the past:
when installing a new WP7 rom, I inserted a new sd card. Therefore I had to take out the battery. After inserting the new sd card, the battery and after installing the rom (doesn't matter which rom), my battery was empty in about 2 hours.
After a long time the conclusion was as follows:
when reinserting the battery, I accidently bent one of the pins that make contact with the battery. This caused a bad contact and made the battery drain very fast!
So what you should do first: make sure that the three pins of the cell phone make good contact with the three contacts on the bottom of the battery.
Believe me, it seems stupid, but it really matters!
I hope this helped you to solve your problem.
Please give some feedback.
Greetz!
Damn, thanks allot for the intel.
I'm gonna try this right away and If It's not helping..I know that It's just a phone issue, so I maby can get that fixed by Vodafone
Thanks alot mainn
a very good question. the hardware pins is a longshot but worth checking anyway.
but... if you do get a real answer to this question, be sure to post back here asap.
search here for 'camera trick' which seemed to help some people but not me
Still sucks.
With android 7 hours. But slow like hell. And wp7 is empty in 30/1,5 hour.
You probably need a new battery, mine used to last 6 hours if I was lucky. Got a new Mugen battery and I get a day out of it. Two if I don't use it much and that's with wifi always on and 3 email accounts updating as well as facebook etc.
