Battery Solution the **FINAL POST**

UPDATE Dec 9:
ALL i did was use Autoboot (Exceller Multiple Build Loader) set at 3 seconds
Try this setup if all else fails
Rom: ChuckyRom Lite HERE
Radio: 2.15.50.14 HERE
Droid: HyperDroid 1.7 HERE
AutoBoot: Exceller Multiple Build Loader for Android/Ubuntu HERE (Comes preinstalled in ChuckyRom)
PLEASE KEEP LEAVING RESULTS AS I TRY THEM, AND CAN UPDATE THE FIRST POST
10/25:
I have been reading and in a recent post I read HAVE THE BUTTON LIGHTS ON WHEN U BOOT ANDROID and u will save battery and its true try this!
AGAIN, PRESS A BUTTON IN WM AND HAVE THE KEYPAD LIGHTS ON.
THEN AS QUICKLY AS POSSIBLE BOOT ANDROID.
I AM CURRENTLY GETTING 3MA WITH SETCPU
I had to try this twice before it worked but THE KEY IS TO BOOT ANDROID AS SOON AS THE KEYPAD LIGHYS TURN ON!

I just posted this in another battery thread but I think the real key is booting Android as quickly as possible and not really the lights so much as I have achieved similar results just using Exceller Multiple Build Loader app and not even touching the keys/lights. C/P from the other thread-->
Tried different techniques to get better battery and found that even on the same build with exact same setup would give varying results. Here's my setup that I would like others to try and post their results. SetCpu with screen off profile set to 245min/max 100 priority and whatever main profile you like; but use conservative preferably or interactive for best battery performance. Any task killer that auto kills all tasks with screen off (be sure to add SetCPU to ignore list). And here is the most important step, use an auto android booting app with minimum boot time setting. I have been doing some experiments with this and found that if you boot into Android as soon as possible, it seems to give better battery performance as opposed to playing around in WM then booting Android. Have tried this with several WM/Android combos. For the first time ever I'm able to get comparable battery performance out of Android as WM. I'm running a bare bones WM (but should work with and WM rom) and using Exceller Multiple Build Loader app set to 3 secs. Even running several sense builds I was able to achieve 3-7 mA draw during standby according to current widget. Took my phone off the charger at about 6:30 a.m. and it is now 11:15 and I still have 25% battery left after pretty heavy usage on standard battery. This is as good or better than what I usually get from WM! Hope this helps.

This was the one thing that was ruining my Android on HD2 experience. I finally got this step right after a few tries.
I've been using it for two days now, and getting consistent 5-8mA readings on standby. There's definitely something to either booting Android quickly and/or hitting the back button to turn on the LED backlight on the buttons.
I just checked my phone, and it's reading 5mA.
And I don't even have SetCPU on my phone. Should I try it out?

I think HTC winmo sense is the culprit. I disable the sense in winmo and get very low Android battery usage during standby. Sometimes around 3mA.

I also suggest to disable sense and put wmo in offline status.

why should turning off sense be good when it comes to battery usage under android? this would mean winmo and sense are running in the background of android...which is not the fact!

You had to try this 2 times before it worked yet you claim this is the final solution for battery drain problems?

i agree with you guys but let me just throw this observation into the mix here. i've read somrthing here in these forums regarding the sd card that came with the phone had something wrong with it ( don't really remember the exact issue ) and if you swapped it out for another sd card, there would be less SODs and a better battery as well.
i've tested this as i have a 4gb sd card and have had no problems whatsoever. everything runs smooth as silk. and, once again, the battery life is great.
NOTE: i do use the keypads lights on trick as well.

Please re-read the post. i updated

Most of us don't need to do keypad gymnastics to get those same results.
Just use the exceller boot loader and set it for 3 or 6 seconds. Having stuff turned off till you need it is a great way to preserve the battery.

Ya thanks for the comment, i was doin this in between class so i didnt have time to just try the Excellor Boot Loader!!!
Updated the First Post Thanks!!!!

well now we hav almost 48 hrs of battery life on android... and moreover i info radio 2.14.xxx is better than 2.15.xxx in battery life...

Not working for me
Sorry thats all not working for me
i'm still having about 60 mA with VBNROM reloaded - 2.15.50.14/ Bangster 1.5 / Scandisk class 2 - 8 GB
I realley tryed everything and have read a lot of posts. I'm really distressed at the moment.
The best battery cosumption i ever experienced was with mccm 2.5 But that one was not stable for me.

1. Are you using SetCPU with a 245 max screen off profile? 2. Are you disabling WiFi, data and GPS when not using it? 3. Are you using a auto task killer with only SetCPU and Current Widget in ignore list? Also, I don't have 3g in my area but if you do I guess it could account for increased battery drain. If you're in an area that is in/out of coverage, this will cause higher battery drain as well. I get spotty coverage where I work and the battery drain is terrible.

Try mdeejay sense rEVOlution 2.0 androind build with your vbn wom rom - works great !
Try this:
1. switch phone radio off in winmo
2. power off and charge until green light comes on
3. boot winwmo on vbn, then immediately click on EBL
4. boot into mdeejay sense rEVO 2.0
5. turn sense off and use LauncherPro
I get *very good* battery life now with avg 5-7mA draw as evidenced by currentwidget.

a few things to try
1
boot into android as quick as possible, 3 or 6 seconds
disable gps location in android
activate the lights when haret is loading
disable wifi & 3g
disable hotspot
disable sync
running htc sense? try a build without it
and many more attempts
im finally at 3mA in airplane mode, 5mA on phone, 7mA with wifi, 20mA with wifi & 3g

no need for keypad gymnastics or other weird and wonderful combinations - before booting into Android, just use KeypadLedControl to force the keypad lights to stay on, then fire up Android using your loader of choice (I use Android Loader, modified to automatically call KeypadLedControl to turn on keypad lights, instead of just letting it run on WinMo startup).
Been rebooting 5-6 times now with consistent low 5-10ma standby current.

The Solution....kind of ;-)
Thx for u'r replys.
I considered all u'r tips and sry dudes it didn't work for me I think the problem was related to the Bangster Build, even though i have been lonesome with my issues.
I changed the LED lib, and tryed to let the LEDs on while booting, set CPU is in condervativ mode/screen off 245min/245max 100% interactiv. And yep, GPS and Wifi where off. I even searched for any SD-Card related Problems in regestry. But Chucky did some great work i think. (i switched again concernig to faster boot)
At some time i think each Leo is different to the other. I changed to Hyperdroid 1.7 with 2.14 Radio and the results are definitely mind blasting.
12 hours on the road, did some surfing, some calls, 2 h musik.
Strange though i used the same kernel and same Radio. Something must have gone wrong by flashing Bangster or something.

[Q] Battery use always exceeds 200mA and wifi tethering doesnt work.

Hello, I have been installing android builds on my HD2 for months now, and have to say the recent development has really left me with a great android phone.
One problem I find I have consistently is that I can never get the kind of battery usage others speak of. Mine trends at 350mA right now which seems wrong cause my battery life isnt THAT bad. and I have never had a build thats had better than 10%->hour.
I'm using ShubCRAFT 2.0 with the hastarian r8 kernel, chunkydroid ROM and 02.12 something radio, i also have an australian HD2.
I keep my screen quite dim, wifi and bluetooth off, no over or underclock (since r8 doesnt support it), no auto task killer.
And while I'm at it my wifi tethering should work based on my build and kernel but every time i check it it says "Error" and third party apps are a no go either.
Any insight would be greatly appreciated.
Also to all the devs, I love you, I want to carry your children.

i always make setcpu, max 619mhz min 254, screen off: max & min 254, auto task killer when screen off and i disable all auto sync, like facebook gmail etc.... im getting acceptable result, around 2 days with normal use

I had just finished reading that list and forgot to try the 3sec. boot which helped. I'm at 10mA now it makes no mention of the wifi tethering problem, any idea on the subject??
EDIT: It flew back up to 200+ after 5 minutes and hasnt gone back down since.

I get 14 Hours standby, but the phone is 4 hours aktivate! I use also chuckydroid. My radio rom is 2.12 and I use Froyostone series !

[Q] best version Android HD2

hello,
i have an htc hd2 and try to install android but all versions i had installed drop battery to 0 after 10 hours
can anybody tell me best android build for HTC HD2?
tks

Hey Sir,
It is always different for everyone, many of these Builds are already really efficient, but here is some tips I would recommend:
- installing some auto kill aps that will kill your aps after your done with it. This really reduces battery usage
-you might want to change from 3G to 2G as that saves a lot of battery
-Reduce brightness of screen to nothing
-turn off GPS
-Turn off Auto-Sync
-Do not use Wi-fi
-Getting a Class 8 SD card i heard decreases battery life as well
Hope this helps,
Luckych

my problem is battery life.
i use advanced task killer , wi-fi and bluetooth off
facebook connection only once per day

Best way to extend battery life...turn your hd2 off.
Just kidding.
I for example use non Sense builds,
and I get about a day of normal usage. If I use the wifi to browse the net it goes down to 10-12 hours. I do not use any task killers.
Edit: now using NexusHD2 build.

now using NexusHD2 build but i dont like the graphics....
i need a android build with nice graphics and good batery life

try one in my signatures. Updated today and most things are working ... hope to get everything working soon !

i am using mdj desire clean.last me for about a day of light usage.
battery problem plauge the hd2 on adroid.its all down to power management.
someone in the forum reported a build that only draws 5-8mah when on standby.which one,i cannot remember,you'll have to do your homework.
one thing's for sure,unless u get a higher capacity battery for hd2,this is the way to go.
and yes,i do know there are extended batteries selling online but they make my hd2 look like some high tech brick.
slim high cap batteries are a rare thing on hd2.

all of the different android builds are good for HD2 as for battery the trick is to start Android as fast as possible after starting your phone if you start it quick enough you will have 3-5mA in standby with almost every build as long as u have an updated kernal. Here is what I do and it works every time . I am using Energy's winmo rom it has a launch Android icon that you can place on the home screen as a quick link or free link. After you restart your phone just watch it soon as sense loads up and you see the home screen QUICKLY tap the home hard key to activate the lights then tap the LAUNCH ANDROID icon

thanx guys

mdj series or cynagenmod series, I like Typhoon...good luck

[Q] Changing Radio, NAND already on

So this is the thing: I want to change my Radio from 2.14.50.04 to a version more compatibile with NAND, because I'm having huge battery drain even in standby (about 109mA due to a CurretWidget). So which one should I choose, and how to flash it? I'm sort of newbie in the topic. And excuse my poor language. Thanks

Your Radio is compatible with NAND. I have the same Radio and i'm drawing 2mA in standby with 3G on.
If you are using any battery widgets (and i don't mean Current widget) stop doing that. Also in Location settings disable the option "wireless connections"
There are numerous topics in regards to battery drainage and how to fix this.

Hi, I'm using radio 2.15.50.14 and i'm fine with it..
To flash simply download the radio from here http://forum.xda-developers.com/showthread.php?t=611787 and it should be a readyb to flash pack.
Turn off your device, and turn it on whil pushing vol down buttun, when you are at the 3 colored screen, connect to the pc via usb (the word serial should change automatically in USB on the phone).
Start customRUU provided with the radio and follow the steps.
It should be all fine then.
hope this helped, bye.

hey guys after flashing my radio from 2.08 to 2.15 my internet/GPRS/Data stopped working, at first it was working fine but after awhile it just stopped working, i tried to mess with the APN settings but its still wont connect, i went back to WM and it STILL wont connect, help please it is really frustrating me! thank you a whole bunch!

[Q] Need Help for less battery back up

I have an almost new HTC HD2. I am testing various ROMs and radios to find the reason for why is my HD2 going through battery so quick.
At this point I am with HD2O v18 ROM and 2.15.50 radio. This is the best combo for me so far in terms of battery use. On standby its very less battery life .This all seems to much to me.but I like to use AmeriCanAndroid .
I also sometimes boot AmeriCanAndroid from SD card, and there it's even worse. 60mA on standby and 120-140 on everything off but auto screen brightness.
I have done so many thing to increase the battery life .Use various Auto task killer apps , keep brightness at lowest level ,removed every unnecessary app from mobile, not used GPS & GPRS . but still this all could not worked for me...
I want to use Android man ... What should i do to solve this problem ? Please help me guys

Hmmm there are many many ROMs with low battery consume...
try a rom with no SENSE - livewallpaper and some hardcore anti-virus program running on the background.
I am using a CM7 Gingerbeard ROM and my standby consume is 6-7mA,
Try A MIUI rom or a Gingerbeard one , Try updating your kernel and i remember i have readed somewhere in here that there is a script that you can run to lower your battery consume..i will find it and post it here
