??? :confused:

Yes BUT 3120 doesnt have 4.3LCD, 1Ghz CPU, all "cool features" (facebook,twitter,weather,mail update...), OS and all that in such slim design.

Ill try one day turn all that ON and i'll update you ;)
[HD2 General] Archer:
Well you're gonna have to struggle with it. I went to bed about 2am with 100% charge (it had been plugged into my PC). It's now on 88% (about 8.5 hours later) and I've been playing games with it. Like I said a couple of times earlier, I now get 3 days out of 1 charge.
[HD2 General] simeezee:
My battery life sucks so much. Can barely survive a day on a full charge. I think it's because I'm on wifi all the time and have very frequent automatic updates.
[HD2 General] iwang:
haha your HD2 won't last a day with all the features on...maybe few hours...and it will run HOT...:p:p:p
[HD2 General] Archer:
Wifi is THE biggest battery killer on the device. If you stop using that you'll see a massive difference.
[HD2 General] iwang:
amazing!!! 3 days out of 1 charge for 1GHz processor, 4.3 lcd screen..games...:eek::eek::D:D:D
[HD2 General] Archer:
If I were to be playing games on it then it would obviously be less than that. During the week I have no time for things like that, and when I do I'm at home. Why would I play a PS1 emulator on a 4.3" screen when I have a PS3 and a hi-def telly?

The only time I really use it for games and/or movies is when I'm travelling. I usually travel around on the train at weekends and will normally get about a day and a half out of 1 charge. It obviously depends on how much I use the device. If I only watch 1 film and play a game for 20 minutes then it doesn't have much of an impact and I'll easily get into the second day on one charge. If I watch 4 films and play games for a couple of hours though, then I'm obviously going to run out of charge within the one day.
[HD2 General] joefosho315:
As an update to my situation, I took out the SD card as well as applying bsb tweaks with power management. And voila, overnight (a period of 8 hours), my battery only dropped 4%! Now I have to test this phone during the day with normal usage to see if the battery fares any better than it used to, or if it only just got better at saving battery in standby mode. I recommend those of you having battery problems with a TMOUS HD2 to try the same and report back.
[HD2 General] :
could you explain step by step what you did please?

I'm super interested :D
[HD2 General] joefosho315:
Of course. Turn off your device. Remove the back cover, and remove the spring loaded SD card. Turn the device back on. Download BSB tweaks 1.6 (I searched google, but it's for sure available here on xda as well). Run the BSB tweaks .cab file on your device to install. After installation, confirm that power management is set to "on." Done. Hope this helps.
[HD2 General] kudepi:
Same situation here. The battery drop after 1 week is still around 7% per hour, even in standby+flight mode. I have tried almost everything, including BsB and complete recharge/discharge cycles plus some registry edit. I am now trying some tweaks suggested in thread "Battery life fix".

I have the feeling that the problem is the SD 16GB card; I have also many mp3s. Some suggest to reformat the card through the phone, I will try it as well.

I hope somebody will fix the battery issue, otherwise I have to give up with Hd2, which otherwise is the best phone I have ever had, but quite useless if it doesn't last a day.
[HD2 General] :
so what exactly is the purpose of removing the microsdhc card?
[HD2 General] simeezee:
Thanks for the hint. I'm going to try it out.
[HD2 General] :
yeah also turn off bluetooth! both hog like crazy.

Can someone confirm bsb tweaks help? I'm trying it now.
[HD2 General] Archer:
If there is a problem with the SD card then it will cause Windows to work extra hard whenever it tries to use it. This will obviously put more strain on the device and in turn its energy source - the battery.

It's a common problem for people who have short battery life, but obviously not always the case.
[HD2 General] :
ahh ok. I think I'm gonna remove everything from mine but fpsece.
[HD2 General] kudepi:
bsb power saving tweak did not work much for me.
[HD2 General] :
I just installed it and enabled power saving.

I also disabled some stuff.

Next, I deleted all music and games off the sd card.

Hopefully that'll make it last longer...

For some reason even though I deleted 8 gb of music, it still says I only have 6gb free.... :/ what's the deal here?
[HD2 General] joefosho315:
It's confirmed, at least for my phone, that something about the SD card is causing massive battery drain. As reported before, on standby, I was only losing about 4% for a period of 8 hours, or roughly, 1% every 2 hours. Now with my SD card back in, in 50 minutes, I lost 15%! What's interesting is that I really don't have much on my SD card besides what came with it stock and a few small files here and there. I guess maybe I'll empty the card's contents and load things back on it slowly to see what the culprit is. So for those of you experiencing battery drain, take your card out and see what happens!
[HD2 General] :
keep us updated! :) my card won't gain memory. once I add something, after I delete it there's n ochange
[HD2 General] kudepi:
How many gb you have in your sd? I am making similar tests with similar results. My sd card (16 gb) is also quite empty.
[HD2 General] joefosho315:
I've got the stock 16gb card with the factory software plus a few small files.
[HD2 General] hc03:
I've been experiencing the same problems with my tmous hd2... ill take it off the charge in the morning, read a few PDF's on the way to work and by the time I get behind my desk its at 85%...

And i think the sd card is a huge suspect to why the battery life may be so bad because whenever i (and apparently other users) delete something from the sd card, the amount deleted is not "freed" although the files no longer show up (eg 16gb card with 4gb of data used stays at 12 gb's free even after the 4gb's are deleted)
[HD2 General] :
yes. I suggest one of us call t-mobile or go in the store and talk to them about it.

Maybe show the local reps what's going on with battery too?
[HD2 General] jehlinger:
Must be something wrong with the sd drivers or something going on with Sense 2.5, it is polling the sd card too often.

I concur the same problem, with sd card in (stock or other) regardless of what files are on the card, the the battery drains about 15% per hour even on standby. With no sd card, the drainage is only 1-2% per hour. Also I notice the bottom is always warm with the sd card in, without it is cool.

I'm going to try it with the sd card in and without sense running to see if it's sense or the device drivers who are the culprit.
[HD2 General] :
awesome, please submit the results to my other thread about the issue.

I'm going to contact T-Mobile once we have enough evidence.

Thanks guys
[HD2 General] hc03:
i think this may be caused by sense's music player... its the only app that really uses the sd card intensively enough to cause that kind of drain via its constant and unnecessary indexing (which causes slowness in itself inside the music tab). This could possibly explain why the files (music files in my experience) dont delete... which would also explain why the power drain continues after these files have been deleted, because they havent really been deleted and continue to be indexed. The only problem here is that this apparently doesnt affect european hd2's... perhaps because sense is slightly different than in tmous roms? i mean there would have to be some changes somewhere considering the extra 1024 ROM space right? hmmm just a theory that someone capable may want to check up on...
[HD2 General] kilrah:
The longest I've done on one charge is about 30h so far. But I'm answering "Satisfied", because it's simply because I use it so much whenever I'm on the move, it's nearly on half of the time I'm away from home lol.

If I'm at home, with data and wifi on, push e-mail activated, but don't actually use it much (read, 30mins of web browsing), I'll lose maybe 30% in the day.
[HD2 General] tri0xinn:
With the stock rom I really wasn't happy with the battery life.. was mediocre.. plus the interface was a bit laggy.. not too bad..

As soon as the spl for 1024 Us tmobiles came out I loaded a few roms.. settled with one and instantly noticed better battery life.. today for example I unplugged at 9:30 AM.. used it a fair amount.. 2 hours of phone calls.. checked emails off and on... used off and on for 4 hours during WWE wrestlemania to check stats of all the guys... installed FCpse and spent a good deal of time testing and configuring the ps1 overlays(still having issues) .. and a little just playing around with it. It's 1:02 AM and I have 14 percent left. Thats around 16 hours.. I can safely say I could use this as I want to and won't have to worry about a charger.. I could see with a few more calls in the morning I could probably make it till noon.. that'd be 28 hours.
[HD2 General] maseo:
It does look like a SD-card issue.

I've recharged my Leo around 12.00 this afternoon (100%).

With almost no use, except for automatic updates of mail/twitter per hour, it's already dropped down to a horrific 44%. That's 56% in barely 3 hours!

I'm also using a 16GB SD as well.. i remember something about a SD card power-saving option with the Advanced Config app. Gonna see if that helps.
[HD2 General] Volw:
There was a thread a few months back regarding SD card battery drain. Apparently, some cards do drain it.

Also, don't install any apps that run in the background on SD card, as the system will be accessing it constantly and draining the battery.
[HD2 General] kudepi:
Yesterday I have tested the power-saving options, which are also found in sktools and in the "Battery life fix" thread.

Unfortunately it is not working.

By the way, I have a friend with a new HD2, but with a 2Gb card, and battery life is much better.
[HD2 General] jehlinger:
I think it's related to an HTC Indexing service or feature. I'm not sure how to disable it though. I'm doing a registry hunt right now. I'll post if I find a solution
[HD2 General] maseo:
NRG's Indexing disabler: http://xdaforums.com/attachment.php?attachmentid=275497&d=1265045188

It does seem to help out a allot!.

Watching the current draw with Tbattery it's now around ± -150 when in use (auto backlight incl. 16GB SD, auto updates per hour, on 3G network, Push-Email) compared to -250ish.

In standby mode (screen off, with SD) it drops to -5 instead of -80/-90

give it a try!

Edit:

It seems that the indexing service is the culprit! I haven't lost a percentage yet in 1 hour, so thats good news!
[HD2 General] S3BAZ10:
so has anyone come with a solution or tips on how to improve the battery life? does the indexing cab really work? i just installed it so im going to see what happens and report back.
[HD2 General] kudepi:
Can it also be the music indexing service? I see that audiomanager is always very active. I have many mp3 files. Is there a fix for that?
[HD2 General] FreakyFerret:
Do you have a link to the info page for NRG's Indexing Disabler?

Where did you get the Tbattery thing that tells you how much draw is going on?
[HD2 General] maseo:
It could be, all i know is that the Cab to which im linking disables the indexing service.

Well it works for me, you could try it out and see if it works for you aswell. It's not harmfull as you can deinstall NRG's cab.

Check my last post. But if you're lazy: http://xdaforums.com/attachment.php?attachmentid=275497&d=1265045188 is the link to the cab attachment.

Link to post: http://xdaforums.com/showpost.php?p=5514730&postcount=6262

NRG mentioned a cab fix in his Tweet, so there's not much info i can find.

For Tbattery, just do a google for Tbattery cab. :)
[HD2 General] hc03:
it didnt work for me, a tmous user...:confused:
[HD2 General] :
From 6:30 to 4:30 mine has been on standby

30% battery drain in 8 hours..
[HD2 General] DeoreDX:
3rd day with my TP2. Did a full charge and discharge yesterday. When I first checked my phone at 7:30 this morning it was at 93%. Now 12 hours later I'm at 42%. Mine is a Tmo USA HD2.

Some relevant highlights.

-Stock ROM.

-Schap's Advanced Configuration tools with all power management turned on.

-Very little on SD card. Maybe 70 pictures, a few videos, all my cabs, and the two movies.

-No MP3's to Index.

-3G on. WiFi and bluetooth off.

-Working in a test lab with very poor reception, fighting to get signal all day spend probably 1/4 of the day with no signal.

-About 15 minutes of phone calls.

-About 10 minutes of web browsing.

-Activesync Exchange setup with direct push on.

-17 emails received.

-1 email sent.

I'm pretty happy so far. About the same I would get with my 8900 Blackberry and my Touch Pro2.
[HD2 General] miguel4u2:
Yea, turn if off :D
[HD2 General] Caliban007:
I let the phone get down to about 3% the day I got it and then full charge over night. Most nights I get it down to under 10% by the end of the night and it stays plugged in overnight to start my new day.

Most days for me start at about 730am and end around 1am (two jobs, sucks but I could afford an HD2 :P ). I talk atleast a good hour or so total, use GPS/Google Maps a good bit, surf the internet, play that damned Teeter game, and listen to MP3s over the speaker and it last me the whole day.

It's 9pm right now and I've currently got 35% remaining. I'm fairly satisfied with this so far!
[HD2 General] NuShrike:
I have WiFi forced off, I was @ 100% around 12.00 today, and now at 20:00 it's at 28% with NO USE except 2 imap accounts updating every 2 hours, and one Exchange updating as things come in. All email should do nothing because WiFi is off and no-data on EDGE or 3G is enabled. As a control, my Touch Pro doing that exact email settings with 2G on and data, no wifi only dropped 10% from 65% to 55%.

This is ridiculous. The only other thing I can think of is it's the HTC Location service.

Turning on all the power-saving options in Advanced Config to see what happens.
[HD2 General] Smartmob:
40 send/recieved SMS

5min calls

30min wifi surf

20min solitaire

40min browsing the phone

(facebook,twitter,weather update,stocks,mail update is OFF, 3G is OFF)

after 72hours my battery is on 25% :rolleyes:
[HD2 General] WizP:
Found one of the big drains on battery!!

Have been looking into the current consumtion on the HD2 for a couple of days now and trying to figure out why my battery drains so quickly even in standby.

The typical current consumption I can achieve is around 8mA in standby. Even if we allow a generous 33% extra of 12mA current draw we should be able to achieve 100hrs or just over 4 days usage with our 1250mAh battery.

Using an app called power guard I've been monitoring the power consumption and noticed that periodically the consumption would shoot up from about 8mA to about 150mA, stay there for a period and drop back down again. So to root cause the issue I loaded up the dotfred task manager and went through each individual process and service to find the culprit.

Turns out that the lock screen app is polling something. After I kill this process I get a steady state current consumption of about 8mA in standby.

There is a simple fix.

I'm using Energy ROMs so the fix is

Go to Programs\Tools\Device Lock and change it to disable. Could some of the fantastic cooks have a look at this a see if we can fix it?

PS I have some of the other power tweaks installed but none work as well as this find!

Can get about 4 days out of the battery if I don't play too much and just use the device as I would normally.

__________________
[HD2 General] maseo:
If that IS the case, trying a new (or different) locking screen would prove that the locking screen is the issue here.

Try that out!

Im gonna log 5 minutes with Tbattery here will on the Home tab going into standy with the lock screen and then standby again, and timing it and upload an excel sheet. it does look like the lock screen jumps up to -270 for no reason.

I'll keep you guys posted.

Edit:

Did a quick log with Tbattery and plotted it in Excel:

this is just a short test. Just keep in mind the usage could be lower because it's also logging at the same time to the phone's memory.

i could test it longer, but for now it just shows that my lockscreen steadies at around ±20mAh and doesn't jump up untill it's reactivated again.

I'll do a new log with the phone in Airplane mode, thus eliminating external usage factors.

Edit 2:

Not much different data.

Standby (screen off) is around 20mAh, with display lit it's around 25mAh.

Active unlock screen is around 25mAh, with jump back to standby peaking at 50mAh temporarily.

Active full usage is around 330mAh, but while 'clocking down' it goes down between 300 and 120mAh, depending on how much is running at that time.
[HD2 General] kudepi:
After many checks I think I have found what is the problem in my case. I have deleted all mp3 files from SD (around 4gb). Battery drain is now around 2% per hour, still not exciting but a stellar performance as compared to previous 7-9%. I have disabled all automatic downloads, except gmail exchange (every 30 min), and turned on all power management tweaks; all applications are installed on internal memory.

Now I don't know what to do, I really can't stay without music...

Does anybody have any idea about the problem with mp3? Indexing? How can I fix it?

Edit: it seems like audiomanager_eng.exe is one of the main causes
[HD2 General] lordofsilence:
I will calibrate it too,but I really need the push-email feature.I am pretty tired of the manufacturers selling great and powerful phones with ****ty batteries....it is ridiculous...all the HTC Sense with these mini batteries.

After almost two years with android and far from winmo and I can see they keep releasing phones with bad battery life and Microsoft still has those windows 98 looking menus and tabs.

Way worse battery life than with the G1 or the Nexus One,those two have direct push email.
[HD2 General] jehlinger:
OK, I've tested these tweaks for about 3 days and they seem to help with battery life considerably. I'm getting about 24+ hours on a charge with push-email enabled, bluetooth on, no auto-updates, about 30 minutes of phone calls, 20 texts, 20+ emails received/sent, about 30 minutes of google maps, about 30 minutes of web surfing.

I have a TMOUS HD2 bought the 24th. Elegancia ROM V2.0 WWE, Radio 2.08.50.08_2.

Apply these tweaks at your own risk, you might have to hard-reset if you screw something up.

Here they are:

HKLM>Drivers>SDCARD>ClientDrivers>Class>MMC_Class>DisablePowerManagement=0

HKLM>Drivers>SDCARD>ClientDrivers>Class>MMC_Class>High_Capacity>DisablePowerManagement=0

HKLM>Drivers>SDCARD>ClientDrivers>Class>SDMemory_Class>DisablePowerManagement=0

HKLM>Drivers>SDCARD>ClientDrivers>Class>SDMemory_Class>High_Capacity>DisablePowerManagement=0

HKLM>Drivers>SDCARD>ClientDrivers>Class>SIM_Class>DisablePowerManagement=0

HKLM>Software>HTC>Manila>HTCService>DocIndexerService.dll (delete this entry or rename to DocIndexerService.bak)

Perform Soft-Reset.

Before I did this, device bottom was always warm with sd card in the slot, now it's always cool. SD card performs like normal, access is just as quick as before. As always YMMV
[HD2 General] maseo:
All these Registry keys will be set to 0 if you have set Power management to Enabled in Tools like Advanced Config, or BSB tweaks.

Deleting the key for the indexing service might be a good one, i don't know if it doesn't do the same thing as NRG's Disable indexing cab though.

Well c'mon! It's not like all the WinMo phones are bad. And if you don't like WinMo, why bother to use it then ?

My Rhodium could last 48 hours + with auto updates, push-email, music, and internet usage without a problem.

No flame intended.
[HD2 General] jehlinger:
Might just not have worked for me, but those two entries in the sub-folders "High_Capacity" were NOT set to zero when I used Advanced Config or BsB Tweaks.

Also, I used NRG's indexing cab and it didn't totally stop the heat/battery drain until I deleted the registry key. Maybe something else is using the indexing feature that isn't in the startup folder?
[HD2 General] maseo:
Funny, mine were. It could be they we're pre-tweaked in the ROM.

I don't have the registry line, but instead of deleting it, rename it to <filename>.bak then you still have the line incase you ever need it again.

Also i'd recommend to disable the DocIndexerService as well.
[HD2 General] jehlinger:
That was the filename, thanks, I've edited my original post.
[HD2 General] maseo:
No thanks.

I've soft reset my Leo after disabling the DocIndexing key and am now running a new Tbattery test to see if that makes a difference.

Edit:

Have to postpone the test till im at home. A quick peek at the data looks promising with the DocIndexer disabled though!
[HD2 General] FreakyFerret:
How do you disable a service in WinMo?

All of my registry settings were 1, changed to 0.

I found the .DLL file, but can't rename using the phone. Am going in with Windows 7's Explorer to do it that way.
[HD2 General] jehlinger:
you don't have to rename the actual .dll file, just rename or delete the reference to it in the registry:

HKLM>Software>HTC>Manila>HTCService>DocIndexerService.dll (delete this entry or rename to DocIndexerService.bak)

Then soft reset.
[HD2 General] maseo:
Im trying to figure out the current usage, though Tbat seems to report the mAh usage wrong.

Also i'm thinking of doing a 10 minute test, just keep it at standby and measure some data.

Jehlinger, you mind logging some info for me as well with Tbattery so i can check your usage and compare/plot it?
[HD2 General] FreakyFerret:
if you tell me where to get tbattery ill test as well searched for it and couldn't find it
[HD2 General] maseo:
Here you go.

extract it to your Main memory, if you want to have it as a program in your program files list, you need to make a link in the /windows/programs folder with for example total explorer.

If you don't do that you need to manually open the .exe file everytime :)
[HD2 General] :
I formatted the microsdhc card and now

standby time

is great.

Since 6:30 yesterday morning it's gone down 70%
[HD2 General] FreakyFerret:
01. 216 mA - 36% (14:13:59) (plugged into USB charger)

10. 341 mA - 36% (14:14:27) (hit Red button to sleep screen)

49. 336 mA - 37% (14:16:28) (was still in sleep)

59. 333 mA - 37% (14:17:00) (was still in sleep)

68. 182 mA - 37% (14:17:28) (hit Red button to wake up)

77. 130 mA - 37% (14:17:58) (unlocked screen)

82. 118 mA - 37% (14:18:14) (unplugged USB charger)

88. -182 mA - 37% (14:18:32) (plugged USB charger back in)

95. -182 mA - 37% (14:18:55) (stopped test)

That's my test. I totally forgot to unplug before running test. But it's interesting it switched from + to - draw. I'm assuming + means charging, and - means draining. Here's test without plug.

01. -253 mA - 37% (14:29:57) (started test)

10. -064 mA - 37% (14:30:24) (put screen to sleep)

11. -109 mA - 37% (14:30:34) (woke up, too quick)

27. -574 mA - 37% (14:31:48) (woke up)

37. -267 mA - 36% (14:32:19) (checked email)

47. -449 mA - 36% (14:32:51) (started Transformers movie)

56. -168 mA - 36% (14:33:19) (load opera and a webpage)

60. -168 mA - 36% (14:33:31)

Those numbers all over the place. I've put the "DisableEnergyManagement" registry thingy to enabled. I still have the DocIndexer running though.
[HD2 General] maseo:
well it's not that bad actually but you could improve i guess.

a negative number means draining and postive charging, yes.

I just formatted my SD through my phone and am currently putting back my data and see if that helps.

Maybe we should all do the same steps for 10 minutes to get even results..
[HD2 General] FreakyFerret:
More tests
