I wonder if the different reports are simply a matter of perception. friday I was doing a lot of browsing, gpz, photos, email etc... and I used 85% of the battery in 9 hours. today, with only email checking and reading on WiFi but with 3g on I used 11% in the same period. what is normal use to one might be heavy to another.

I have applied the reg tweaks from this thread, and have twitter updating hourly, weather 3 hours, and location services on.
[HD2 General] Chainfire:
My HD2 is completely stock. No extra software installed. It was taken from the charger friday afternoon, it is now sunday evening. I have 27% charge left. I am not running WMLongLife on it (yet).

I have used it to make a few phonecalls, but primarily to surf the net (a few hours, combined, I guess) on 5 bar HSPA signal.

Have any of you with a low percentage (when it should be all means still be high) rebooted your phone? Often you get a completely different % after a reboot. May be relevant in this case (or it may not).
[HD2 General] chilau:
Just running powerguard on my HTC now, in standby with all automatic updates off it draws 3mA.

Watched a video on youtube with 3G and it draws 400mA.
[HD2 General] nicelad_uk:
There are many different ways to determine power management and for someone that is not used to windows mobile.. this isnt the most useful answer.

Do you actually know what DisablePowerManagement actually does? I mean when you enable the powermanagement what is it actually changing. Yes it puts it into standby mode but do you know what it will effect by doing this?

If you do, please answer the question as we would all like to know!

And apart from the Power Management, how about the other settings, please explain them too before you flame a post, have some respect man and help out, its what these forums are about!

If people are not 100% sure what these settings are doing then although they might stretch your battery life 10-15 minutes longer, it may also effect your phone and what you want to use it for, like stopping your push email when in standby mode, text messages can sometimes be delayed when being received etc.

I recommend (which I have done with all my phones) is the Reg edit to close programs rather than hiding (stops unneccesary usage in the background) and also the disconnect of data after certain time (unless your using push which means it wont work). Also try disabling the my location as that eats a lot of juice when updating and the screen brightness. (not my favourite as this makes the device a bit unbearable in the sunlight as the screen pushes the brightness up to make it viewable.

There are many reg tweaks and i'm sure they will work in one way or another, but also know what they are doing or you might stop your phone doing what you actually want it to do.
[HD2 General] Nit3m4re:
Nicelads said everything worth saying lol. Disable things that you don't think you'll use, and regedit things you are sure you know it will change.

As for me, I have a new battery now, my first battery seemed to leave me with awful phone usage after just a couple of hours. My new one, after a full 100% charge, from 8AM this morning after a good amount of use, phonecalls, internet, texting, a good 2.5/3 hours music im down to 45%. Its now 9.04pm for me from writing this. I had all the power saving stuff on with my old battery, but to keep it fair, i uninstalled all of them, to see if this battery made a difference. I kept my location disabled because that is useless to me and I can honestly say a new battery has made a big difference.. I don't want to be the one to say all go and buy new battery's but for me, using a new one has improved my phones life by a large amount. Using my phone on the first battery like I have today, I would have been lucky to get 6 hours use from it lol.
[HD2 General] GeitjeG:
Using 2 days now, much improvement in battery uptime. I also use the tweak which makes the data connection disconnect after 1 min. And auto screen brightness control is disabled for me...
[HD2 General] tboy2000:
How long exactly did you charge your new battery? Over night or just until green light came on?
[HD2 General] Nit3m4re:
I used it down from the % it came charged at to around 10% then charged it over night as I needed it to be full for work the next day, so that was an 8 hour charge basically
[HD2 General] erosennin:
Someone here mentioned having a bug that could make the phone drain power.

I might second that, had my battery charge overnight. Went to work put flight mode on, browsed some pics for about 10 min and in 5 hrs the battery drained down to 50%.

Came back home, recharged my battery to full, I was filling the calender with appointments for say 15min max and the battery drained by 10% all this with auto updates off.

Two days ago, I left my phone on with location + weather update on, made a few calls, some text and some photos and in 12 hrs it only drained itself by 33%. There must be something that's causing the battery to drain.

I can't come to grips, how making a few phone calls + text + autoupdates on causes the phone to drain by 30% and with flightmode on and briwsing a few pics the battery drained by 55%. It's either the battery meter reading erroneously or else there's something that's staying in a high power state or god knows what.
[HD2 General] mr_Ray:
Has anyone with battery problems tried checking the task manage to see if there's anything with a high cpu usage going on? Just a thought...
[HD2 General] Danielfr:
My battery is draining faster since I have installed Second Today (http://www.chi-tai.info/cs_wm_tools_im_cs.htm#SecondToday)

It hasn't drained my previous HD
[HD2 General] erosennin:
Sometimes I do have programs using lots of memory but the cpu usage would be at zero. Maybe memory usage drains the battery?
[HD2 General] scilor:
I would not use the SD-Card Power Safe mode, it deleted my sd-card 2times in my old kaiser!
[HD2 General] br3nt:
I am noticing the same crappy battery time as threadstarter, so im gonna give these changes a go (won't use SD settings, heard bad stuff bout it :P )

however, it would be nice to know how the power management works in these comm ports. if someone uses windows vista/7 (spec. 7) you'll notice when connecting the phone to a new USB port it start installing ndis drivers... ;)

hopefully I'll remember to tell you how it went (if i noticed any difference)

current battery :: 58%
[HD2 General] d3l1:
now that I'm using my phone on a work-day basis I charged it about 48 hours ago and I still have 70% battery left. I didn't use it that much in those 48h of course, I had to work a lot, but all in all I'm really impressed.
[HD2 General] Pixel:
On Friday, lots of browsing, GPS, photos etc... I got through 70% battery in 7 hours. On Sunday, wifi on, email checking regularly, 3g connected but not being used, no browsing, I used 5% in the same period. I've applied the tweaks at the start of this thread. All in all, that seems about right.

Yesterday, I used 80% battery in 6 hours of on-and-off-but-mostly-on music (around interuptions) but with 3g off.
[HD2 General] vangrieg:
A question to people who have the battery drain problem: do you carry your device in your pocket/pouch most of the time when this happens? One reason I can think of is this wake-up-on-any-button behavior that the HD2 has. You may accidentally power it on all the time so the backlight drains the battery.

Does it sound as a reasonable hypothesis to you?
[HD2 General] erosennin:
You are bloody right, it could well be the case.

However, how do you disable the keys while the screen is off? Atleast 4 out of 5 keys.
[HD2 General] jabbawalkee:
All i know is that I've been running tests on the battery life of my HD2 and the results are HORRIBLE...

Today, after a full charge, I started with the phone at 9am and used it til 2pm (with minimal browsing, 15 mins of phone calls, some texts, and auto syncing turned off as well as using power management reg tweaks). At 2pm, my phone was at 30% so I decided to charge it for 30 minutes, which made it about 45%. I started using it again around 2:30pm, with little use, and it lasted until 6:30pm. So, in total, the phone lasted about 9 hours, which is being a bit generous. I'd say (without the charge in the middle of the day) that it'd only last 8 hours.

This is awful in my opinion and, frankly, I can't keep a phone with such horrible battery life. I'm thinking maybe some of our phones are just straight ****ed for some odd reason. It's weird because some people have reported battery life of up to 50 hours!!

Any ideas on what I should do? I'm thinking of exchanging it for another phone from the ebay seller I bought it from (if i am able to)
[HD2 General] aBE-One:
jabbawalkee, how's your network coverage? If it's borderline non-existent, then I could perhaps accept those numbers as "possible". However, if you have good coverage most of the time (GSM or 3G, doesn't matter as long as it's 3-4 bars) I'd say there's definately something wrong. Oh, just to be sure - you might want to run one other battery life test with a freshly soft reseted phone just to make sure there is no chance that some program has crashed and is draining the battery in the background. If not... try to exchange to another sample, or if that's not possible I'd contact HTC's support. 8 hours battery life with light use, as you described, is definitely not normal!
[HD2 General] 20mihalko:
second that.. i hope it is only some "bad" app
[HD2 General] aBE-One:
Has anyone else experienced camera-initialization problems after applying these tweaks? I applied some tweaks (some the ones in this thread and a couple unrelated), and shortly after noticed that I can only start the camera app once after a soft reset. On following attempts I got an error message "Camera initialization failed", or something to that effect, and I was back to the home screen. I then reverted most of the changes I made and it seems to be working now, but I'm not sure whether the problem was with the tweaks presented in this thread, or with some of the other tweaks I applied.

Also, as I've now disabled these tweaks, I'm curious has someone who noticed an increase in battery life after applying these reg tweaks, reverted back to the original settings and noticed that the battery life got worse? And perhaps then again applied the tweaks followed by again better battery life.

I'm just wondering because when I first got my HD2 the battery life wasn't much to brag about. I then applied these tweaks for a few days and sure enough the battery life was improved. But then I noticed the problem with the battery and reverted the changes. By this time I've had my HD2 for about a week, and I'm quite happy with the battery life even with these tweaks disabled. So, what I guess I'm suggesting, is that is it possible that the "increased battery life" might be (only?) due to battery conditioning after the few first cycles, and less so because of these tweaks? What do you think?
[HD2 General] shu8i:
after some days of full use and using these reg tweaks i definitly got the full day usage, maybe more.
[HD2 General] Biffy:
From 100% my phone has been on for 71 hours. It's now 25%.

It's been on 2g all that time, with SPB Shell. Admittedly I've used it very little in that time, one short phone call of less than 20mins and probably less than 30mins web browsing and switching off alarms.

But I'm still pleased that it's not sucking up power too much when not being used.
[HD2 General] dugald5:
To be honest, I have found the battery life to be fine. I am in a 2G only area but have wifi on all the time and it doesn't seem to drain very fast.

That said, I have a car charger, a usb cable at work and a usb cable at home so I am surrounded by ways to charge the phone up. Perhaps that is why HTC put in the smaller battery - the fact that most people have access to chargers most of the time? I guess for those who don't there are the ugly extended battety packs...

I am certainly happy that they kept the phone nice and slim rather than putting a fat battery into it, but I can understand people who don't work in front of a computer all day being a bit miffed.
[HD2 General] elburna:
@Jabbawalkee if you want to, you could do a Log with battlog and i would have a look at it and compare it to the ones i made. My phone lasts over 50 hours with average use (30min Phone, 30min Video, 30 min Games, 30 min Browsing and some messaging/ email (all togther in these 50 hours, not per day).

For me there where two secrets which brought a big improvement.

1. I use S2U2 and noticed, that when i dont check "device off if not used for x minutes" in the windows battery-options my hd2 would never go to real standby. instead it uses about 40-60 mAH per Hour which is faaar to much. Also battlog shows a very obvious decrease of consuption after two minutes (thats the value i set the "automatic off function" to)

Dont know if it is the same with the WM6.5-Device-Lock

However in flightmode and standby it should not consume more than about 5-8mAH, thats how HTC measures :) --> 1250:8=156h Got that Info from the repair manual of my old HD, shouldnt be a too big difference to the HD2

You might want to check this with Battlog. Just leave it running in the background for an hour in flightmode and youll see wether you have a mainboard-leak or something or not

2. Comparable effect when i turn on the HTC-Location-Service (or how is it called on WWE-Roms?). Quite big drain, when switching it on. Not constantly but from time to time it eats up over 80-100 mAH for some minutes. Since i turned this off battlog didnt notice any consuption like this again (allthough the function is not explicity mentioned in the log-file)

Right now i got no problems to get over two days of use without charging
[HD2 General] jabbawalkee:
Sounds good man...I'm getting a LITTLE better battery life now (which I can deal with), but it's nowhere near 30-50 hours. I will download battlog now and leave data syncing on and then send you the log when I get it. Should I just let my phone run with normal use for 24 hours or until dead then send you the log?? What's your email man? I'll post here if I don't here back. Thanks a ton
[HD2 General] arturobandini:
After several days of test, several tweaks, my conclusion is that battery life is really bad on the HD2 (compare to the HD).

I don't know what drains the battery so much. Hope HTC will prepare a HotFix quickly.

For now my only solution is to disable the automatic backlight and set the backlight to low...:(
[HD2 General] jabbawalkee:
Btw how do I run the log with Battlog and what file do I need to send to ya? Gimme some instructions cause I don't know :)
[HD2 General] elburna:
In Battlog go to update/log, logging and specify the store location of the logfile. Then click on update/log again, tap "10 seconds", then tap logging --> start logging. Dont forget to minimize battlog instead of closing it. If done with the log, just stop the logging and the file will be saved

You best try, lets say, 2 hours in flight mode with nothin running in background. In a second test you could just use your phone normally without all the automatic update-stuff running.

In the storage location will be a *.log file. Thats the one you need.

Afterwards just post it here in the thread.

I must say, that my batterylife improved a lot but still (even with everything of but phone) there is some quiet heavy consumption noticable in the BG... something aroung 80-100 mAH. Cant figure out what that is, maybe kind of technical leak or bad programming of the phone software??? Dont believe that this is the search for the network because i got good coverage here. If so that would be also a no-go by the phone/htc. Far too much. Thats why i dont always have that good running time with my battery. Some times its good sometimes its not (under exactly the same conditions... WTF?). Just noticed that today --> 22 hours dead (very light usage)...

EDIT: Dont forget to send your settings (light etc.)
[HD2 General] Audio Oblivion:
i am noticing the same... its not consistant atm...

however... i have only had the device a week.

the battery on this device isnt that great but it could be simply perception on my part. i am moving to this from a samsung omnia i900 which had incredible battery life.
[HD2 General] aussiebum:
Using S2U2 and making sure "Don't Suspend Device" is *UNCHECKED* under the Advanced options seems to help with battery life too. Before I had that checked I was lost like 10% battery in 1hr. Now it's holding steady around 82% and it's been another 1hr since I made the change.

Having said that, the HD2 is draining faster that my HD when doing absolutely nothing though, because I didn't have to use that suspend option before with S2U2....
[HD2 General] elburna:
Yeah i am aware of that option. But thanks anyway for pointing at it, maybe other users dont know...
[HD2 General] jabbawalkee:
Okay so everytime i run a test i hit the 10 seconds option before hitting start correct? Also, how long should i run the log for when i do a test of battery life for normal settings (automatic sync and such)? I dont know if ill get to airplane mode tomorrow just cause i need to receive calls but i can do a test on battery life with normal settings (as im doing now) and one with data and everything turned off. Just let me know how long to run the test
[HD2 General] elburna:
Well depends on what you want to check:

If you want to know if it is the Radio/NetCoverage, make two tests under same conditions. Lay the Phone somewhere for one hour or something in Flightmode and then make a new Logfile to do the same without Flightmode. Just an example. Its as easy as that: The longer the test, the more reliable are the numbers (but i think an hour should be enough)

If you want to know what eats up your Battery in everyday use. Just log the whole day and do everything u would always do with your phone.

At the end it is very helpful to put the data of the log file (which is not more than a txt-file) into an excel-sheet but jut if u want to and got some time left :)

And yes, u have to select the 10 seconds thing everytime before u start a log. Otherwise BattLog will only record something if theres activity (p.ex. your phone connects to check email). In the meantime you would not know what the battery consumtion is, as BattLog simply doesnt write it into the Log-File even if there are Changes (p.ex. bad network-coverage isnt an activity but rises your current consumption.)

I have to say that theres another Problem: BattLog doesnt know the HTC-App´s activities. You will just notice a rise in drain but there wont be any tag for the event/activity started at that moment. But you can guess.

Okay enough of talking. Dont let it become to complicated. Just make some logs under different conditions and watch if u can spot anything unusual :) For me it was just, that my phone doesnt go to sleep if that damn option isnt checked. Dont have a clue why (maybe ill try a hard reset soon)...

Greets
[HD2 General] jabbawalkee:
Awesome thank you :) I'm running a battery test right now (and have been since about 7:47pm), testing the battery with normal use (auto sync, playing on the phone, then letting it sit on standby for a bit, the usual). So far my battery is taking a beating haha. I'll post the log after I let it run a bit more.

Later on tonight I'll run a one hour test of the battery in airplane mode (and I'll play around on it for the first half, then let it sit in standby the second half).

Tomorrow I'll run a test from when I pull the phone off the charger until it dies.

I need to get to the bottom of this ****. I think I'm going to buy a replacement battery online tonight to see if that makes any difference. It is possible that my network may be draining the phone but I'm not too sure (I'm in the United States, so I can only get EDGE on AT&T). Expect a lot by 9pm EST. Thanks.
[HD2 General] jabbawalkee:
Okay so here's my log: Log7.48pm.log - 0.04MB

I started logging at 7:48 pm and ran it until 9:05pm (Battery was at 67% with 30% brightness, also I have a tweak installed that disconnects data after 60s. Mail/twitter are set to sync every 2 hours)

Here is a list of times and what I did throughout the logging period:

-10 minute phone call

-Opera and file explorer backgrounded from 7:48 until 8pm (notes and battlog were backgrounded throughout entire logging period)

-64% battery at 8pm

-Manual sync of email and twitter, sent a few text messages

-Screen was on until 8:12pm (59% battery)

-Screen off until 8:17pm (58% battery)

-Surfed web for 2 minutes until 8:19pm (57% battery)

-Screen off until 8:42pm (55%)

-Woke phone and refreshed twitter a few times and posted a couple tweets

-Screen off at 8:48pm (55%)

-Screen on at 9:01pm (53%) -- made 1 minute phone call and screen was on until I ended logging at 9:05pm (53%)

So basically battery level went from 67% to 53% with normal usage in about 1hr 15mins.

Check log and let me know what you see. I will try and run a test of battery level while in Airplane Mode later tonight.
[HD2 General] jabbawalkee:
And here is the batterylog running a test on my battery life when in Airplane Mode. I let it run for 1 hour without messing with it at all, then for the next 45 minutes or so I turned it on a couple of time to mess around with it.

I started the log at 9:21pm with 50% battery and just ended the log at 11:08pm and I'm at 45% battery (which is pretty good) -- drop of only 5% in 1 hour and 47 minutes. But, this is Airplane Mode :(

Here's the log: Log9.21pm.log - 0.02MB

Thanks in advance!
[HD2 General] neverdude:
Google maps and battery drain ?

Hello

I have noticed that there is a big difference in battery drain after using Google maps. The battery having a quick drain:(. I make a soft reset and its back to normal :) ?

Somebody else have this same HTC Leo HD2 experience ?

I think for some unknown reason the GPS is working on the background, without seeing it in task manager.:confused:
[HD2 General] skr_xd:
you are right.

I was thinking the same yesterday when I get a very quick GPS fix.

May be the GPS hardware is on permanently:confused:

May be we shall try disabling GPS from registry.
[HD2 General] danielherrero:
Hi.

When my device isnt using GoogleMaps is uses 220 mA (known using CommMgrPro). Witch Googlemaps running it uses 347 mA but after closing googlemaps it comes back again to 220 mA....

Dani
[HD2 General] jabbawalkee:
Okay, don't know if you saw my logs from last night or not. But, I ran some more battery tests consecutively today testing normal use (ran two logs because I accidentally stopped the first one):

Battery Logs - 11.19am-1.36pm_1.37pm-5.43pm.zip.zip - 0.01MB

Settings:

-brightness set at about 30% most of the time

-backlight dimmed after 30s/turned off after 1min

-automatic sync of ActiveSync (every 4 hours), Mail (every 2 hours), Twitter (every 2 hours), and auto sync was turned off for Stocks and Weather.

Log 1: I started the log at 11:19am with 86% battery and ran until 1:36pm (55% battery) -- I accidentally quit BattLog -- 30% drop in a little over two hours is not good though

Log 2: started at 1:37pm with 55% battery and ran until 5:43pm (10% battery)

I did not really try to conserve battery in this test...I wanted to see how the battery would run with normal use and checking of e-mail, twitter, weather, and stocks as well as making phone calls and text messages. I'm not too impressed with the results. The battery seems to be dropping at about 10%/hour and when I tested the battery in Airplane Mode last night, the results weren't THAT much better. I'm not sure what to do, but if someone can look at my logs and let me know what they think the problem is, then that would be awesome. I have to figure this out.
[HD2 General] tsttse:
how about when you listen to mp3?
[HD2 General] ATomCZ:
I turn on flight mode on the night and my HD2 lost 30% of the full capacity in 8 hour. I think, that this is not so good :-( I'dont use it for this time, all wireles modules was turn off.

How I can recognize when device sleep or only display is dimmed?
