The idea of this post is to make a statistic research about the battery drain problem. Maybe this will make us understand the cause of the battery problems -since I couldn't find something that solved the battery problems of all users.

There are 3 solutions (they are post in Faria Wiki)

-And a third solution is to Flash a ROM with FULL battery & let it drain comletelly afterwards.
---------------------------------------
Using the "battery status"today add-on I can say this:
The first time I installed faria 3.3 ROM I had huge memory drain problems
I notised that even in stand-by my phone "ate" about 124mA
The registry memory tweaks didn't change this much - maybe 118mA.
The battery in this codition lasted at most 18hours...
I reflashed Faria3.3 with the mobile FULLY charged,let it discharge fully and now I have 84mA consuption if phone goes to sleep and 97mA when not used. Now battery lasts about 48hours without much usage.
With the [HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms] etc keys changed and with manually shutting down the Wireless Monitor Service(WMS7) was 42mA .
Note: I have Faria3.3 ROM & GSM 2.19 .
In another mobile phone I checked, with 2.17 OS rom & GSM 2.06.10 radio, I see that the when phone is not used the battery drain is 24mA !!!!!
This phone does NOT have the registry tweaks enabled and even with backlight it still stays in 24mA..
Please, post your mA consumption here and say what you have enabled.
Btw, anyone knows why Wireless Monitor Service(WMS7 was enabled (started) even though I have turned off WiFI,bluetooth & IRDA?
152mA, was ALOT higher when i had 5+ programs running, around 200
I have Faria's WM6 and run about 57mA in standby, 125 during normal operations.
Here is my first contribute to this outstanding forum.
Hope this is usefull insearch of the power drain on some devices.
Note:
My phone does NOT have the powermanagement registry tweaks enabled.
And is an clean install with the Faria WM6 (The real Thing) rom.
So there ain't much running.
Just ordered Wisbar Advanced + desktop so hope to see more readings later this week after fully fine tuning my device.
My device
Orange SPV - M3000 Faria WWE WM6 (G3 Unlocked)

BatteryStatus incl Tray applet
Running Hardware
Bluetooth= off
GPRS= off
Radio= on
WiFi= off
IR= off
Power drain Bat= 100% charged
Wakeup: 70mA (after 5 <-> 10 minutes)
Softreset: 258mA
Hardreset: 350mA
Standby + 50% backlight: 302mA
After charging: (and pulling the plug out) 180 -> 250 mA
All readings do not change until i manualy interrupt the current status off my device.
I mean if my device after wakeup says 219mA the reading does not change even when i run different software apps.
Even if the CpuScaler clocked 130mhz the reading will not change.
I think that BatteryStatus is broken or something else is interfearing with the readings.
i went from 175mA to 125mA... just by going from 0 to 1 with the next tweak:
HKLM/Drivers/SDCARD/ClientDrivers/Class/SDMemory_Class/DisablePowerManagement
i use Fario's rom..
trying other tweaks now..
ok:
so without doing anything it just suddenly dropt back to 64mA.... :\
ok:
booting takes 280mA
I recommend not to use these ::: they sucked out my battery even more.. from 125 to 247

Today i did made two changes on my device and noticed the following.
First i updated my Radio rom from 2.19.11 to 2.61.11. (No errors everything works fine)
I just wanted a better radio because the signal strengh overhere is verry bad.
This update has on my device an nice site effect.
Powerdrain dropped by several mA.
Wakeup: 61mA (after 5 <-> 10 minutes)
Softreset: 201mA
Hardreset: 299mA
Second i messed with the key
HKLM/Drivers/SDCARD/ClientDrivers/Class/SDMemory_Class/DisablePowerManagement
I did not notice any effect on this reg tweak
I am using Wizard 100 ( Cingular 8125)
EDGE ON 24x7

decient battery life: fully charged battery comes to 1.5 days..
--tux
i dont know what i did.. but its at 42mA right now.. and sins my last post.. it was @ 76% battery.. and right now its @ 75%... that means more then 12 hours have passed.. and its only down by 1 %...
last post was @ 01:30 PM...
WOW!!!!!!!!!!~!!!!!!!!!
like i said.. it took a really long time for 1 %..
but the moment i sent an sms message... it went from 75% to 71%..!!!
damnnn
Seems as if batterystatus is broken: my readings dont update either: it seems stuck at the same mA-value all the time, no matter what I do, or which clockspeed I use...
Also: the powermeter keeps at 99% (had been 83% as well); it never changes : (
My battery from 100% to drop to 99% might take 8-12 hours , then from 99% to 90% might take few hours (maybe 1-3 hours).
This seems to be normal.
I'm using the mA consumption because if you have an 1250mA battery I think this is the best unit to measure battery.
My apologies, but which program are people using to measure battery life consumption and how does one tell which program is causing the problem? In the past week, I have noticed my battery life take a nose dive and I'm wondering if it is pRSS Reader that causing my problem. I installed a power saving cab found on this forum site and I will test it tonight. Thanks for the help.
It might also be worth considering usage of GPRS, Push email, WiFi, BT, etc.

Be careful of power saving cabs. Some of them actually increase battery consumption.
I think most people are using battery status to check consumption.
BTW:
At wake up: 24-30 mA
When the phone has a signal, the consumption rate is low 24-30 mA throughout the day. When it is searching for a signal (normally at my work), the consumption is substantially grater. When I get back home the consumption goes back down to the normal 24-30 mA (I always have a signal at home).

No,
I never applied the fix.
I haven’t done enough research on the fix to justify applying it. Maybe when I get some extra time.
The signal goes in and out at work, so it's not a big deal for me!
Running an 8125 with Faria's WM5 3.3 ROM.
When I wake it up it's usually 51, or somewhere in the 50's anyway.
I just tried those powermanagement reg tweaks and had terrible results too :\
My wizard can last 3 days with moderate usage of wifi, phone calls, and movies. This happened after I followed the Battery Solved thread and reflash with official ROM and then I installed Xplore1.1. And for the first cycle after first time after fully charging overnight, I can get the 3days of continous battery life..
Since then, I have been monitoring CPU usage and it hovers around 1-5% (Battery status) when idle... Bear in mind that the current consumption value can be around 33mA to 150mA and still battery life seems to be good...
Weird but through...

Dear,
I have upgraded my HTC Touch from WM 6.0 to 6.1. I have faced the big problem of Heavy Battery Drain. I was confused. I try to find out the solution over XDA Forum.
My problem was, "after charged 100%, then after 5-10 menutes it goes to 80%. and then it start draining very fast."
I have changed the registry for :
[HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms]
"DisablePowerManagement"=dword:1
Change to
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms]
"DisablePowerManagement"=dword:1
Change to
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms]
"DisablePowerManagement"=dword:1
Change to
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]
"DisablePowerManagement"=dword:1
Change to
"DisablePowerManagement"=dword:0
and Set the Wireless Monitor Service from Automatic to Manual.
But, I still have the same problem, why after 100% charged & after unpluged it goes to 94% thereafter 88% and within 5 menute it goes to 80%.
Thanks to the XDA Forum Members, help me out.

With the HD2's pretty short battery life compared to my previous HTC phones, and also as I was a bit bored , I decided to have a look at how much the different systems drain in the HD2, and did some tests.
So for anyone interested, here are the results:
Base consumptions: (pick the one that suits your situation)
Standby, phone on, WIFI+BT off, no connections active: 5mA
Processor running idle, screen off, connections as above: 55mA
100% CPU usage (Coreplayer benchmark), connections as above: 315mA
USB connected, connections as above: 125mA
Additions: (add this to the base one depending on what you have on)
Connections:
BT on, idle: +1mA
Wifi on, idle: +5mA BUT!! If you enable wifi during standby (with BsB Tweaks or the WifiNoStandby CAB), the processor does NOT go to standby
anymore, so the base needs to be the 55mA above!
Connected to EDGE, idle: not measureable
Connected to 3G, idle: +4mA
Beware those 2 will occasionally and unpredictably send data every now and then, so this doesn't necessarily mean much.
BT transfer (file copy through ActiveSync, 120kB/s, CPU usage ~2%): +80mA
Wifi transfer (file copy with Wifi Remote access, 1MB/s, CPU usage ~3%): +200mA
EDGE/3G transfer: Pretty impossible to measure due to so many variables, but can be extreme (total current consumptions of 850-1150mA, so very approximative 500-800mA draw from the data connection during page loads are common!), and leads to most of the energy draw when using the net a lot. EDGE uses more power than 3G, consumption is higher when network coverage is lower, bad network throughput or congestion also mean lots of retries/overhead and less effective data transfer, using power for a longer time until the data is finally there.
Memory access (large file transfer):
Internal read/write through ActiveSync (speeds 2.5 / 2.1 MB/s respectively): +20mA / +130mA
Card read/write through ActiveSync (speeds 3.2 / 2.7MB/s respectively): +25mA / +40mA
Card read/write in USB disk mode (speeds 7.5 / 5MB/s respectively): +40mA / +45mA
Backlight:
10%: +65mA
20%: +78mA
30%: +90mA
40%: +105mA
50%: +121mA
60%: +136mA
70%: +154mA
80%: +170mA
90%: +190mA
100%:+210mA
GPS:
+95mA
Flashlight (with HTC Flashlight):
Level 1: +32mA
Level 2 (same as camera flash on): +107mA
Level 3 (same as camera "bright flash during shot"): +530mA
And remember the battery capacity: 1230mAh
So with this you can calculate your battery life for various activities. For example:
- Playing a video with full backlight: Let's say the video is well encoded (30% CPU use, for example 720x400 1Mbps DivX), that's about 150mA base, + 210mA backlight = 360mA, resulting in about 3h20 battery life.
- Same at night with only 40% backlight: Life goes up to about 5h!
- Wifi during standby for an 8h night, or a program that somehow prevents the phone from entering standby: 60mA or 55mA respectively, draining about 40% of the battery during that time.
- GPS program, with 70% backlight: Let's assume 150mA for the processor as it has some work to do, 90mA for the GPS, 154mA for the backlight = 394mA, or 3 hours.
- Music through wired headphones, screen off: the 55mA base plus a little 5mA as MP3 decoding is nothing for the CPU = 60mA or 20h.
- Same with a BT headset, with about half the BT bandwidth: 60+40 = 100mA or 12h
etc.
Charging
[EDIT 14.04.10]
This is now a dedicated section as I did some more thorough charging tests.
So, as some of you might know, the HD2 has 2 charging "modes".
- One is USB, that is used if the phone is connected to a PC, or an unknown device. In this mode, the current the HD2 will draw from the port/charger is limited to approx. 470mA, to stay within the maximum of 500mA a USB port can supply.
- The other is "dedicated charger", which is recognised on the original HTC charger (and some others, it's becoming a standard for a "dedicated charging USB port") by shorting of the 2 data pins of the USB connector in the charger.
USB charge
Important to know, during USB charge, the phone will NOT go to sleep, as it's supposed to be connected to a PC, and be running either ActiveSync, Disk drive mode, or modem, and in all 3 cases would be expected not to shutdown. So not only the current supplied to the HD2 is low, but the phone draws some of it for itself, leaving very little for actual charge - so expect loooong charge times.
USB charge with screen on (backlight dimmed, 10%): 285mA
USB charge with screen off (standby): 345mA (which shows the processor still runs and draws the "base USB" current)
Dedicated charger
When used with a charger that has the 2 USB data pins shorted, such as the original charger, the HD2 will draw a current that is proportional to the voltage on the USB power lines. To measure this I have used the original supplied USB cable, a variable regulated power supply, USB socket (with data pins shorted), and 2 meters for voltage/current. Voltages are measured at the "PC" end of the USB cable, so not taking account of losses in the USB cable. Will talk more about this later on.
Current vs Voltage diagrams are attached. Charge current is proportional to voltage, linearly until it reaches the max charge current, approx 830mA. This was measured so that the only draw is charge. If the phone is turned on while at max charge current, it will draw extra, until it reaches about 980mA, and will then stop to respect the 1A rating of the stock charger.
Now, to the influence of USB cables. I initially had some trouble with inconsistant numbers, phone only drawing 670mA from the stock charger, i.e matching neither the ~350mA from USB, or ~830mA from stock charger in "normal" condition. Turns out that to make it more convenient on my workplace I was using an USB extension between charger and HD2 cable. It was a $2 extension I bought on Dealextreme. Removing it solved the problem... and after making those measurements I poked with it again. Turns out that at 1A current, the voltage drop in the extension (which by the way isn't longer than the HD2's USB cable) was 1.8V! Yep, nearly 2 Ohms for a 1.5m extension! Couldn't believe it.
I have a cheap Chinese microUSB cable that wasn't as bad,but still significantly more resistive than the stock one, hence me noting I used the stock cable for my tests. So, quality of the cables, extensions, adapters IS important! Note the phone correctly reaches full charge current a little bit under the 5V USB spec, so everything is well tuned.
Now, important to know, Most 3rd party chargers will not have the 2 USB data pins shorted, and will thus result in the same behavior as mentioned under USB charge, the processor will also be running continuously drawing the "base USB" current.
It is often possible to modify 3rd party chargers by opening them and shorting the pins, speeding up charge. The voltage/current curve behavior is actually helping there, because thanks to it if the charger is overloaded its voltage will most likely fall a bit, and the HD2 will thus draw less and find a nice balance point. This DOES NOT mean there's no possiblilty of damaging the charger, but all 3 I modified did well. One that was really weak resulted in not much more current being drawn after the mod than before (i.e voltage fell very low, approx. 4.4V), however the gain from not having the processor running like in USB mode still sped up charge a little.
Thank you, that is one useful chunk of comprehensive information
Could you please explain the exact measuring method for these tests?
40% backlight at night is a tough example tho, Lumos on my device is set to 10% for 0 sensor value, and only because I can't set it to lower than 10%... nice to know battery drain goes up twice from 10% to 60%!
Also, 100% is usually really necessary under direct sunlight, in a normal lit room probably 40% backlight is more than enough to watch a video... all in all, with your superinteresting info, the battery doesn't look like lasting "too short" now, but more or less "the right amount considering the battery capacity".
My iPaq 210 has a 2200mAh battery, just to make a comparison... that's why I could go for 8 hrs during some bus trips while watching tv series, and I just needed to swap battery and used a little of the second one.
What's your estimate of the drain caused by activating push email? I've recently been doing some rather crude experiments myself, and one provisional conclusion is that push email on a hotmail account uses a lot more battery than push email on an Exchange server.
Excellent stuff, you are to be congratulated.
I have a long held theory and I wonder if you are in a position to to test it?
I believe that battery consumption is greatly increased when an app is run from mem card and would be intrigued to see a comparison between an install to this as opposed to phone mem.
Any chance?
Battery levels
I found that power consumption of the battery got even worse after I went to Rom 1.66.707.1. However, after a few days, I let it run all the way out, switched back on, it ran out after a few minutes. Then after an overnight charge I found the battery (on standby) only went down by about 10 -12 % in 24hrs. I'm hoping this performance will continue.
What did you use for the testing?

That would be reasonable as reading from an external media will need energy to access its contents... still, once the app files have been loaded into the device's RAM, it shouldn't matter much
You could also test by comparing:
1) copy say 30mb from one location to another of the internal mem
2) copy from microsd to microsd
3) copy from mem to microsd
4) copy from microsd to mem

Simply using the built-in current sensor, getting the reads from AEBPlus battery information screen, and methodically turning things on/off once the others are evaluated and can be subtracted from the total reading.

Really? You should force the backlight off then
I love bright images myself, so even in my bed in total darkness if I watch a video or photos I'll force 100% backlight I have Lumos set to force 100% for Coreplayer, Resco Photo manager and HTC album
Of course not for browsing or just messing around, in that case it's 20% for me

That's one thing I'd have no idea about... I've never used push email at all. And that's "standby usage", so hard to evaluate, as you never know when it kicks in.
Measuring that would need to be done on a long time. I'd say to leave your phone one night with push email off, one night with Exchange only, and one night with hotmail only, and then check the difference, preferably with a battery at about 80% charge at the start (mine seems to fall from 100% to 90% in a few minutes before becoming more regular, so I'd say the top of the scale isn't that reliable).
And I should really try push email once, that would be nice, but I *think* I have no provider that can do it for me... well I have a gmail account I never use, I should try to see if I can have it check my usual 3 mail accounts, aggregate and push... never really looked into that stuff.

Well I'd tend to refute that theory, because when I tested the BT and Wifi in use I tried read from internal memory, write to internal, read from card and write to card, and all 4 were identical. I should have mentioned it indeed, but I was mostly interested to seeing if reads (wifi/BT "sending") and writes (wifi/BT "receiving") would have an influence on consumption, which wasn't the case, as well as whether the throughput was different, which wasn't the case either.
But I've done a few more tests, see the updated first post
One intersting thing is firstly that when the HD2 is connected to USB, the current draw grows significantly, so I've made a new "base consumption".
Next, the card is actually faster than the internal memory both in reads and in writes, tested both through activesync for consistency. Writing to the internal memory eats a LOT more than writing to the card. Reading from the card eats a little more than reading from internal memory, probably evens out as the reads are shorter due to faster transfer rate.
I've added some charging tests as well. Apparently, even if the phone "disconnects" from USB when turned off, the processor still runs and uses about the "USB connected" base current.

d'oh aebplus has a battery information screen, checking it right away In that case you'd have to take into consideration aebplus' current absorption anyway... which is not measurable as you cannot check the current intake of aebplus without aebplus being running
I have the cab on the sd already, but didn't install if after noticing that didn't work for button assignments with later versions of the rom... does it work for you on that side? I used the program all the time on my previous ipaq because it was oh so useful but never got around to notice it had a battery info subsection.
Really? You should force the backlight off then

Wouldn't have much sense doing it in the dark would it (admitting it's possible altogether on the HD2!)
But I actually used my oooold casio cassiopeia, about 7 years ago, with backlight turned off, while reading ebooks with speed reader plus during train trips, as the neon lights created a reflection good enough on the display so that I didn't need backlight...
in the end, the backlight died altogether and until I bought a new device, I managed to use it with light turned off
A flashing LED (incoming SMS warning, e.g.) seems to add consumption of 1-3mA.
Running FlexMail in background with a push service (IMAP IDLE) adds up to 30mA.

AEBPlus works fine for me yes... but I don't have a "latest version" ROM AFAIK. I don't like WM6.5.x new softkey arrangement, so I'm staying with 6.5.
Anyway more about Push, I configured that through gmail yesterday, and it works just fine. I left it on during the night, and this morning I had lost 8% battery. So it's pretty much negligible. I received 2 e-mails during the night and was on 3G network.
this is a nice topic! i am interested in how much extra it uses when you are playing a MP3 with the build in HTC app?
maybe it would be a nice idea to make a program that outputs results like you pasted fast and easy (something like a benchmark app) so we can test different rom's fast? too bad i cant write anything otherwise i would try..
OK, seems MP3 uses 120mA screen off, both with Sense player and Coreplayer, so:
Processor running idle, screen off base + 65mA
But it seems to make some pretty big "jumps" once in a while. Maybe they both decode ior fetch from memory by "batches"...
my test,
HD2 rom 1.66
with BT on and BT off (configured but no connection to headset) difference in consumption is 60mA .!
BT is draining my HD2 .!

But it seems to make some pretty big "jumps" once in a while. Maybe they both decode ior fetch from memory by "batches"...

OK, I can't confirm the BT issue. Did you observe over a long period of time? The "quiet" current for MP3 I seem to get is 185mA with screen on and backlight at 10%, but sometimes it will climb to 280-320mA for a moment and go down again, both with BT on and off. With screen off for a while it seems to stabilise at the "quiet" level.
BTW, it seems that Advanced task manager isn't reporting CPU usage levels properly. Does someone know of a CPU monitor that works correclty on the HD2?
Yup. review over multiple 6 mins. all baseline(3g/brightness) setting the same. resetting each time for off on BT.

Another consideration:
Data connection sucks power when used actively. Badly. As mentioned in the OP I haven't made comprehensive tests due to low monthly allowance, but I've had a look during normal use.
I'm pretty regularly doing 1hr train rides, during which I will be listnening to music , and browse the net at the same time. It's usually bright, so backlight will probably be at 70%. Signal is relatively low most of the time, on EDGE, inbetween small towns. When I'm on a "static" page (reading an already loaded page), current drain varies between 250 and 350mA.
But while loading a page, it will easily soar to 800mA+. Considering it takes 30-60 seconds to read a page, 20 to load a new one, and repeat... you can quickly see that this kind of usage leads to serious drain... in less than 2 hours the battery would be dead.
So be aware of how much power data connection will use. It's directly proportional to the amount of transferred data, and the worse the reception the more power it uses.
I should try using opera mini again, like I was always doing on my Kaiser. I never noticed excessive drain with it, but opera mini easily divides traffic by a factor of 10...
Just wanted to report that the new version of the superuseful BattClock has now a builtin battery current output, even if it's not really update once per second... seems more like one every 10 seconds.
I get ~240mA playing fullscreen stretched Frasier in lowest backlight (but that's with the keypad leds turned on all the time, I don't know why they don't go off, and I don't have keypadledcontrol installed... so that's a problem), and I get a total 630mA with HTC flashlight at maximum.
Good news! Bye bye Batti
Normal about the refresh time, the sensor only updates every 20 secs or so.
Some new considerations I posted somewhere else but should have put here.
After some time the HD2 seems to have better battery life, but usually it's not your battery lasting longer, it's just you not spending your day playing with the thing anymore.
It's always the same thing, the more a device can do, the more you do with it. On my first 1h train journeys after getting my HD2, I was able to kill 50% battery in 1hr. My first thought was "wow, with my Kaiser I would only use like 15%!!"
But then I took a second thought. I used 50%, but I was browsing the web, in bad reception areas, while listening to music the whole time. With my Kaiser, I'd put music on, check 3 webpages, then put it on the tray with just MSN connected and just pick it up to read/type a message once in a while.
On a next trip, I "forced myself" to do the same with the HD2. Just checked the news for 5 mins, then only listened to music and picked up msn once in a while, plus an unexpected 10min phone call. Guess what? I've only used 20% battery during the trip this time
The "problem" is that browsing with the Kaiser was just painful, so I'd just check the news and put it away. On the HD2 it's so comfortable I forget it and just spend my whole trip browsing heavy pages, which obviously kills battery in no time...
exactly my thoughts and findings
For some reason no matter what build, radio or rom I use BatteryMinder tells me that I will get better life with wifi on vs wifi being off. (check jpegs in attachment)
If i turn mobile data off too I get better battery life as well.
Why is the Mobile network killing my battery?
I would guess this has something to do with 3G that gets disabled on WIFI start
Yea I figured that how do I fix it though?
I stop using batteryminder because the time fluctuation was killing me! one minute it would show 1 day of battery left after unplugin, and 5 minutes later would show 15 hrs left, but only 2% had dropped in the battery, I guess it reads everything that's running, and takes it into consideration to tell you what time you have left. I get like 3 to 5mA at idle so I don't need it anymore to tell me how much battery I have left, I get a full day of battery.

This is a known fact, the wifi radio uses alot less power transmitting data than the 3G radio. I have about 20 Wifi access points stored in my phone so that it connects to them automatically like Home, work, church, parents house, friends house, that way the only time I'm actually using cell data is when I'm in the car. Saves the battery a ton.
If you want to use 3G all the time, but save battery, turn off always on data in the settings and set it to sync on an interval instead.

Odd, when I enable WiFi and set it to never sleep (so it keeps WiFi on when screen off instead of reverting to data), I idle at 10 times higher mA than with WiFi off. When actively using the connection (browsing, etc) it does seem less energy consuming than data, though.

Same here. Idle goes up to 70mA with no sleep.
I set it to "never when plugged in" and it seems to work fine.

This is all excellent advice. Cheers roloracer! I use similar settings and software for the most part with Core Droid HD v.02 by Sergio76 right now, and the standby drain with WiFi and GPS on, auto background data sync off, sits much of the time at 7 mAh. This is without using SetCPU. Moreover, with WiFi and GPS off, the standby drain drops down to about 5 mAh on average. This is about the same as I get using EVO Black & Blue Remix v.03A with everything off as well. That said, both of the above mentioned builds are incredible, IMHO, and both include the hastarin r8.5.1 Kernel.
Best to all,
R
If you are in an area with spotty coverage, and constantly switch between 2g, 3g, H, etc... then it supposedly runs your batt down a lot more than in steady coverage.

How much mAh do you have when you use your phone and how much
When It's in standby??
I got 3-6 mAh in Standby and 110-400 when using the phone (500mah when using the camera)
With this info my phone only last around 10-13 hrs

10 to 13 hours of heavy usage is not bad, light use is a different story, even on windows mobile with heavy usage you can see about the same 10 to 13 hrs of battery, My phone averages about the same as you, at idle with the screen off is about 3 to 7mA , with the screen on but nothing extra running about 120mA, and with stuff in the background about 250mA, or with the camera is about 400 to 500mA. The key is to always check advanced task killer, kill all before turning off the screen, I use my phone lightly to medium during my work hours, I text a few times, facebook a few times, some phone calls, but during all this time I keep my background sync data off, I only turn it on if I have to go into the market, and I turn it back off after I finish in the market, then when I get off work, like 13 hrs after I unplugged from charger, I usually still have about 50% to 60% battery, I flip on the background data and go full blast on it, til the end of the day.
First - let me state - and it is true - that I used the search function.
I read pages and pages of advices to lower battery consumption on my HD2 Android... without success...
First I used an SD ROM. I read that a NAND would improve battery life. So this is what I did.
I am also using SetCPU with a profile when battery <30% and another one when screen is off to LOWER the CPU speed. In normal use, I set CPU speed at 768MHz trying to lower power consumption...
I use a task killer to free memory and prevent silly programs to drain my battery off...
I use Juice Defender to control wifi, data, etc...
And with all of this in place, my "Current widget" shows a consumption of 180mA with screen on doing nothing, up to 350-400-500!!! mA when acutally using the phone wifi+sync...
In the forum I read consumption like 3 mA - 9 mA!!! This is FAAAAAR Way lower than what I ever had with different builds...
So this is an help scream to everybody: what is your battery drain, and why mine is sooo High???
Hint: I am also a fan of LCD Density changer, with setting at 165... can this have an influence on battery drain??? I reverted to the original 240, doesn't seem to have any influence...
Thanks for your help,
Looki
My drain is 3-9 ma in STANDBY ONLY now and again slightly more but mainly the values stated. And my screen on between 120+160ma. Turn off auto brightness if you have it on, and set it at the lowest your comfortable with (display is big batt drainer) I DONT use taskillers as they do more harm than good. I use NO undervolting and only the default settings with my rom. I have low lcd density setting 167 i think. Lcd density has no effect on your battery drain!
Found this here. http://forum.xda-developers.com/showpost.php?p=13151738&postcount=11296 Might be of some use to you? (from hyperdroid gbx thread)
Whats youre rom?
And do u use ext partition on sd?
I dont even use SetCpu anymore. Only taskkiller.
Auto-brightness is on
Auto sync is off.
Im using UD 3.3 nand from crawlingcity
Stansby is 3 -6 ma
Using round 160 to 250.

How long does your battery last from 100% to self shut down? As for Current Widget, keep in mind that when people say "Standby", its generally referring to the screen being off. Set current widget to update every 30 seconds, and turn the screen of for 40 seconds. Then quickly turn the screen on, unlock, and check what it is reading then.
If its still high, try "Force Stop" applications in the Settings > Applications menu one by one, i've had to do this more than once to locate problem apps that were destroying my battery in standby mode.
I'm knew to Android, let me share you my idea.
I use UD3.3
I removed google stuff
gmail, search, etc
No auto sync
Location off
Always kill market when screen off.
I use beautiful widget for weather manual refresh.
I use battery widget
Auto level for screen
sometimes WIFI on
2g Only
2 or 3 calls,total of 3 to 4 min a day
My battery stay 48 hrs in STBY mode.
I think the most draining factor is
1) google stuff they are battery hog.
2) screen
3) bad written programs (every time they check connection to
internet or looping for doing something, looping will make
CPU in high frequency).
4) bad device driver such as BT which is known as 60ma
drain. it is not the hardware but it is the software doing
the drain.
thanks

Hi!
I installed NAND rom on HTC HD2. I have battery problems (I think).
I left it for sleep for 6 hrs. I turned of bt,mobile network wifi. He lost nearly 15% in that state. I received only one sms. I cant get battery through day. Is that normal or i have problems ? Also i would like to know is there any program to se battery wear out level like on laptops so I can know to replace it. Thanks in advance
Adition on battery stats now i have 12% 16hrs since charged 14.5 stand by 1.5 up time. Is this normal?
try controlling running operations at background. i use android assistant for this. use battery monitor widget for battery information and statistics. at sleep it should consume 2-6 ma. be sure auto sync is closed. control screen brightness, it eats battery very much. with some kernels after activating bluetooth it consumes 60 ma battery in standby until you restart. for good battery life prefer cm7 roms (i'm happy with hyperdroid

Use CurrentWidget from the Android market (free). Just put the widget on a homescreen, put the device to sleep then after a minute or two check the battery drain.
