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 !

Possible soluition to fix 60mA: Enable GPS and wait for full sync

Hi friends.
I found the following coincedence.
When I install new build aparently CurrentWindget shows 60mA in stand by and no way to fix it to 5-7mA as it should be.
The solution which helps me to fix it is the following:
- enable GPS module in settings
- open Maps and wait for it to find where you are located
- go back to homescreen and put phone to stand by
It should be fixed now to 5-7mA current.
Hope it will help everyone.

I can even leave GPS module on all the time after that - standby current stays at 5-7mA level.

Very strange, but very cool if it works for you! I will give it a shot next time I see high battery drain. Thanks for sharing, it will help at least one other person if it helps you.

I've also found that switching Bluetooth off, then back on again, fixes this 60mA drain !

Common misconception: leaving GPS enabled in settings doesn't leave the GPS chip on the whole time. It just means that an app can enable it when it needs to (e.g. when you open Maps). As long as there's no GPS icon in your status bar, it doesn't drain *any* battery.
OT: that trick would be way faster than rebooting! Gonna try if it works for me too.

Really strange solution for this issue. I have the same problem but for this moment have drain about 5mA after quick boot with dualbootloader (wait time 3sec for Android load). For this moment 5mA in standby mode - with any enabled comm modules (WiFi,Bluetooth,GPS).

My experince of fixing the problem(temporary) is not using taskkiller too often, but it not always works

Don't ever use your task killer again, it only causes problems.

Tried the above however no sucess..........please check out my post and tell me what you think

Why? I use it a lot...

To solve 60mA problem, each time you want to boot android:
1) when you are in windows mobile, lock the phone and turn the screen off by press end call button
2) wait few seconds and press it again to turn on screen
3) you see lock screen, unlock your phone
4) after that boot your android quickly within 10 seconds! (you can do it by creat shortcut of android on your home sceen)
I test it and solve problem for me on both mccm and mdeejay builds!

It was discussed hunderd of times. You dont need to free up mem in android 2.x
It has already a memory management built inside.
The only reason to use a task killer is to close an app that hangs or not properly close itself.
If you continue to kill your processes and backround apps just to free up ram, you will definitively drain more battery becaouse some of that apps will just load again automatically from SD or, when you open again one of them, it needs to load again from SD.

Exactly. And apps not closing properly is still not an excuse for using it. If the app is bad uninstall it or mail the dev to fixit, but don't go around screwing stuff up with a task killer.

Autokiller on agressive,and a taskkiller....never troubles with drain etc

Or everyone check my signiture for my thread on battery drain solution

I think the OP is really onto something here. I tried this trick & my drain has gone from a steady 55-65mA down to around 5. I'm impressed!

Just one question, those of you that having issues with battery drain what WM do u use? I've recently had a problem on my HD2 (no USB) and i installed a stock ROM. Before i had the VBN Droid Reloaded 2 and with Mdeejay kernel current widget never showed me values above 300mA (witch i believe i only saw that value 1 time). Usually i'd get from 1-2mA to 250mA tops. Now i'll never go below 60mA and i've seen the record of 600mA. Today it drain me from 95% to 35% in about 2 hours. A bit too much for my taste...

I always find if you boot Android with Win Mo fully booted, it's over 60mA, but if I use Exceller Dual Boot to boot Android before Win Mo has finished loading, then it's 5-6mA.

Yea man task_killer - problem

Everything is working for me fine, i am using futureShocks MIUI build, the only thing is when i switch on bluetooth, my battery drain is about 60-80 mAh without bluetooth i have 3-6 mAh... no task killer, no setcpu, with other builds like mdeejays sense roms this problem is not !?
Everyone an idea how to solve the problem ?

[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

editing your build prop using root explorer is the best place to start,i've got my battery to read FINALLY 0mah when screen is off,ppl didn't believe me at 1st and doubted me,but then once they followed my instructions,my inbox was full of appologies and thank you's lol

[Q] Battery Drain VS Rom?

I know theres alot of topics about battery drain, and some methods have worked for some, but I am still stuck in the loop.
I'm using Back to the Future (XBmod-Yuki/7740) - and have tried The Camera Trick, 2.12 Radio, and Registry tweak (battery indicator) and all have failed, i get around 8-10 hours battey on minimal use, (Facebook app for 30min and 8/9 text msgs) [note: 3g and Data on]
and I was wondering is anyone noticing any difference on other wp7 roms? or is that rom specific?
Thanks in advance

Apparently i've got the same issue as you, I got 3 hours off it with intensive use today ( 2.12 radio, no battery fix, but it was draned down to zero )
I'm also using the back to the future rom ( But it's registered as 7720 )
My device is eastern europeian.

I'm back on winmo
i will try wp7 again (HD2O) (7740) but with different SD cards, hopefully i get a lil better life
ill let you knw how that goes

And i'm gonna get an android SD these days to compare.

with lightly use, my HD2 WP7(Back to the future 7740) ate battery so quick. I'm trying to flash pdaimatejam's v2. Hope to get some changes.

Okay to CONFIRM
Booted pdaimatejam's v2 on lexmar 8gb (class 4 )
Radio: 2.12
and so far used 10hours
and still 54% battery remaining
3g and data is ON!
Location OFF
Live Tiles disables (have to manually update hotmail etc, no push)
Tooks round 40pics, used FB app (Biggest drain)
and few small video clips (2.mins each)
also 70-100 txts snt and recieved
im happy now

yeah i was struggling with battery life for a while too.
the camera trick seems to have helped a lot. i get almost 2 days with normal use with location, 3g and data all turned off. i am going to do the registry trick, then turn location, 3g and data back on to see if anything changes.
EDIT: the registry editor that works with mango does not allow me access to these registry files. oh well.

Android SD was still not the best I've tried. while the ROM had more battery life then yuki's back to the future, it still left me 30 minutes before I was ready to let it go.
Today on WP7 i got 3.5 hours with: the camera trick,(Switch to video and leave it running, right?) also no 3g no Wi-Fi and no Location/Bluetooth. Brightness all the way down ( snowy weather ) . Where can I find the instructions/guide to installing pdaimatejam's or is it included in the download?

Do we have to use camera trick every time we reboot HD2? How about the reset command from MDLDR menu? Do we need use it every time we replace battery?

reboot should be fine, bt i tried the HD20 rom over last few days (radio 2.15) and battery drain whilst standby is AMAZING! with 3g on over night it drained like 5-7% battery, but when using browser, whats app etc battery drains too much :S
