Battery Solution the **FINAL POST** - HD2 Android Q&A, Help & Troubleshooting and Genera

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.

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] So what is currently the most stable setup for android on HD2?

So about 1-2 months ago, I switched to Android on my HD2, but this wasn't a very good rom. Whenever I turned the screen off, it would only light up black (wtf). It stated the battery was empty all the time. And when I had to restart my phone, and tried booting into android again, it would either freeze on the bootscreen, or it would be the darkest screen ever. Sometimes both.
So I ask; What is the most stable setup to date, for HD2?
I would also like to know which is the most stable Android build to-date (i am not bothered with the HTC Sense layar).
I agree ^^
Right now I'm using mdeejays evo sense 2.3 revolution and upgraded the kernel with Hastarin R8 and it is very stable!!
Its gonna depend on many factors such as what WM rom you're running and what radio as well. I would recommend you get chuckdroid WM rom, a good recent radio, and either evo sense 2.3 or Bangsters 1.5 (if you dont want sense) Ive had good results with both.
Latest Energy WinMo ROM, 2.12 radio, the Android build linked below.
Works fantastic, all day, every day. CM6 mod. MDPI/HDPI hybrid too

I like my setup (in my sig). There's a new skinnyEVO v1.5, and since I haven't tried it, I can't speak of its stability.
The issue you'll encounter in most Android builds is data dropping, which is caused by using PPP (not RMNET) connection. This can be 'fixed' by turning on/off airplane mode.
+1 for Mdeejay builds
just loaded Mdeejay eVo Sense v. 1.1 Matted this morning, so far v smooth, battery 5mA in standby, camera with flash working, no probs so far.
deff' the best of the 3 android builds ive tried

I'm on O2 in the UK. Using the latest Sense version of the PhireMOD Skinny EVO (v1.5) with 2.15 radio and the latest Chucky ROM 23139 ~ 3.14. Rock solid stability and very smooth and fast. I get an occasional data drop but that's the same with every PPP build. Battery life with light usage is approx 2 days.
Just upgraded to V8 kernal and it's smoother than ever. Best andriod build i've used - apart from the data drops (which is not the fault of the build) it's pretty much perfect for me. The key is to get the right combination of radio/wmrom/andriod. Unfortunately it seems to be different for different people so just a case of trial and error until you find the right combo. In my case the switch to 2.15 radio solved a lot of issues.
energy and skinnyEVO v1.5 with latest kernell update is the best setup you can get.... after a long search i foud this one to be the best..... oh radio 2.12.50.xxxx great battery life..... >
energy rom and mdeej's Revolution is by far the best sense build to date and there is a new radio for those of you that dont know yet 2.15
There is no guaranteed catch all perfect setup. what may run perfectly fine for me may run absolutely horrible for you. Different strokes for different folks.
Factors you have to consider:
SD Card (class, size, whether is SDHC or not, how it is formatted, cluster size)
Battery calibration (does your battery last a long time in WinMo?)
Your own knowledge (if you cannot be bothered to search for any simple problems then you WILL get frustrated trying to run Android)
the best way you can find out the best setup for you is trial and error.

Sorry for the noob question, but can somebody describe data dropping to me?
I got a HD2 from work on the weekend, so the first thing I did was install android
I installed: Radio_2_14_50_04, and FroyoStone_Sense_V3.2. This combo is working fine and seems stable.
The problem I had yesterday was that I could not access the internet although I had a strong 3g or H signal. The problem would suddenly disappear and access would be fine for a few minutes and then no access again. Access seems more consistant today.
Battery life seems a problem too, it was fully charged at 7am this morning and was down to 5% by 5pm, that was with mild usage apart from about an hour mp3 and 30 min gps.
Any of this sound normal for android on a HD2?

reboot Android at least three times and the battery usage will improve drastically
my juice lasts a full day of moderate to heavy usage.

Thanks for the info...the airplane mode trick worked a treat
When you say reboot android 3 times, do you mean reset the whole device, or is there a way to shut down and restart the android os?
Cheers

I use:
VBN reloaded 2 minimal ROM
mdeejay revolution 2.0
radio 2.12.50.
One time deals:
i) turn off auto backlight in winmo
ii) do a g-sensor calib in winmo
Make sure you :
i) Load android using EBL *as soon as you possibly can*
ii) press the back button when its loading HaRET
and you are all set !!!

[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.
Sent from my Nexus One using XDA App
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

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.

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] 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
