I searched all over the forums but couldn't find this posted anywhere, and I wanted to see if this was a known issue. I'm using an T-MOUS HD2, with Dutty's WM 6.5, and AmeriCanAndroid SD. For the past 2 ACA builds, I've had a period, when first installing that standby drain is about 5ma, but at some point soon afterwards it jumps to 60ma on Standby. On a hunch I disabled the security pin lockscreen, and it dropped back down to 5ma on standby. Enabling the pin again made it jump back up to 60ma on standby. Does anyone know if there is a fix for this? I would like the longer battery life, but still be able to offer a small bit of security for the device.
Thanks.
update: culprit found
Upon further investigation it seems that the culprit is the "Disable Lockscreen on Security" option in Cyanogenmod settings->Lockscreen settings. If I have both the swiping(rotary) lockscreen AND the security PIN, standby drainage stays at 5ma. bizarre...
Thanks, that worked for me too!
Switched two days ago from Hyperdroid to Typhoon which is based on newer CM7 and noticed reduced battery lifetime. Indeed Current Widget was showing about 60mA current.

Hi.
I installed MoDaCo based on 2.1 official last day. I am not sure if this problem affects all 2.1 or just mine, but since then my phone battery gets drained to death in half the time it happened when i got Cronos 1.4.1 with updated radio.
When i check the battery usage in BatteryLeft widget, i notice that wi-fi eats almost half ot the power over a 6-7 hours span. This makes me think that probably this 2.1 release has a problem on putting wi-fi on sleep.
As a note, i also have overclock widget working and i've read the other thread were people seems to have problem in having their phones changing to sleep status when pressing the sleep button.
Should i just uninstall oc widget and check if that's the one causing the problem, or we are talkign of a recognized bug from 2.1 which prevents wi-fi from going into sleep mode?
Hi all!
I tried yesterday [AUG12] AmeriCanAndroid AOSP HD2 GB2.3.5 CM7 build from SD card.
This was my first Android experience with HD2 and must say that i am impressed.
Didnt expected that everything will work so flawless. Deep respect to creators of this build.
I noticed only one problem so far. When i turn screen off (red button) and when i try to turn it on again there is a lag presence (3-10 secs) and again sometimes it turns on instantly. Is there maybe some fix for this behavior?! I mean i can live with this but ...
I have played with device intensive for 2 hours and than i leave it with wifi turned on overnight and battery duration was almost 14 h. Is this good because i dont know what to except from SD build ??
And should i use some autoloader before HTC Sense in WM loads as some advise to maximize batt life or that is no longer necesarry with new builds like this?!

This is a known problem with SD builds, don't worry it is normal.
To check the battery, use Current Widget from the android market, it should show 5-8 mA in my personal experience with the ACA SD build, although some people get even less than that apparently. I think that 14 hours seems a bit low, try using JuiceDefender (Android market) and SetCPU (here on XDA) to maximize battery life.
You may as well disable HTC Sense in Windows if you don't need to use it, and use an autoloader to load Android automatically, makes the whole thing more convenient and I also saw a minuscule improvement in battery life.
Thank you.
Current widget showing cca 160 mA drain in standby with JuiceDefender turned on (wifi and gsm are turned off).
Without JuiceDefender drain was about 230 mA
How to get such low values like 5-8 mA.
Android is started via haret.exe from WM (latest official 3.14 rom)?!
Hi everyone,
I have used an older version of Hyperdroid over the past few month, which worked very well for me overall. Usually the battery managed to last a couple of days.
However, after I tried some different Android NAND Roms on my HD2 yesterday, I reinstalled the latest version of Hyperdroid (HyperDroid-CM7-Observant-Opossum v5.9.0) and noticed a dramatic increase in battery usage.
It drains about 10% in less than an hour without using it.
- WLAN off
- mobile data off
- Blutooth and GPS off
Androids battery use overview lists:
Display 35%
Cell-Standby - 33%
Idle 29%
Wi-Fi - 4%
There are barely any additional apps installed.

Install currentwidget and place a widget on your homescreen. Tell us the battery drain when the screen is off by setting the refresh interval to around 20, leaving the phone to settle in standby for a minute or so and unlocking it and giving the drain immediately displayed (don't wait for it to refresh again) and it should be around 4ma with everything but the phone function itself turned off. Try it in airplane mode as well, here it should be around 2ma. If you mean high drain with the screen on then you're just going to have to live with it unfortunately.

Yes i would definately check sleep drains. But if its when your phone is on, it may also be an update in the CPU governor settings. I would switch to conservative. Especially if you dont game a lot. You can also try changing your CPU voltage levels.
What's your kernel and governor? Any OC? Maybe the kernel isn't allowing deep sleep.

did you do a clean install?did you wipe your battery stats?
if you post some more info about your device then we can help you even more.
i would try changing the governor and then battery calibration (you can find it on the market). i had this rom and if i remember correctly there were some issues with my battery too. i then got the 5.10.0 version and everything became normal again.
or you can upgrade to the latest version 6.0.0. i just installed it runs smooth as hell!!!
good luck!
Even I'm using the same rom and the battery drains heavily only when using applications and playing games. But can anyone help me how to upgrade it to version 6.0 with detailed instructions.
Sent from my HTC HD2 using XDA
so, i am having a lot of fun with my HD2. And since a few months i have ICS running and in the mean time i have 81 apps installed.
What is so strange is that all of a sudden the last weeks i noticed that the battery drain without using the phone at all! I am used when leaving the phone at the side of the bed at night, the battery drain in the morning would be 10-20
%. ok by me. But now in the night without using the phone the battery drain becomes 40-50%!
how do i find out what is changed on the phone, or what is happening for this drain to occur?
i can go to settings and the tab energy gives me an overview of the things that used the energy. Even in the night it is the screen? how can this be?
there's an app that can show you your current drain but i can't seem to find it
https://play.google.com/store/search?q=current+battery+&c=apps
or your battery is dying out? how old is the battery & is it an original one?

@OP if you're using SD Android see this thread, it should solve it for you. I had the same issue. If on NAND, you need to check what you've changed to get such high drain. It should really only be around 4mA with data on, 2mA in ariplane mode and 5mA with wifi on. Turn off all unused connections, kill background apps, increase sync intervals etc.
I tried to search but the results were not conclusive, so decided to start separate thread.
I installed NexusHD2-ICS-4.0.4-CM9-HWA V2.9a on an SD card to try it first, and I am running it from Windows Mobile through haret. Performance is good, everything seems to work fine, besides the battery life. It drains the battery in about 10% an hour. On Windows, it can last several days with the same type of usage, so it is not the battery.
Better battery stats does not show anything useful - it reports that the main consumption comes from the OS itself.
Nothing seems to alter that behavior significantly - I wiped and installed the ROM again, so that there are no applications of my own running. I turned off wifi, mobile data, and changed connection to 2G. That causes only minor variations in the battery drain. Played with the cpu governors - same thing, just minor improvements.
My device is T-Mobile HD2 with class 4 SD card. I used PPP when installing the build as the other setting did not work for me.
Has anybody experienced the same behavior? Do you think I will be better off if I put the ROM on NAND?

Try using NAND it does reduce battery usage by some percentage. But don't expect a big change in battery drain , it is common issue that we all are facing.
Battery should last about a day on normal usage. 10% per hour is a lot. Is your screen turned on? Screen takes most energy of all. Turn intensity down and let it turn to sleep in 30 secs or 1 minute.
Also, frequent battery checking drains battery too, so leave the phone alone
Don't use tools as juice defender, my opinion is they take more juice than they spare.
Sent from my NexusHD2 using xda app-developers app
and let the rom settle down for a day or so
becuase you cant really tell what the battery drain is after
a fresh rom install
Ok, if the range is around one day, then I do not think there is anything specific with my installation. It can be weaker battery or too much screen time. It was just too different than on win.
Thanks all

Battery drain will always be an issue as the battery really is too small for the phone. Have you tried setcpu or similar these cpu management programs seem to work to a degree in increasing battery life.
