Simple Trick To Get 4-11ma In Standby

First, sorry for the new post on this, but I have not seen this mentioned. Didn't want it buried before it could help anyone.
I have used pretty much every android ROM out now, and for some strange reason they each have one constant.
ROMS which give 54-67ma on standby on first boot can be reset a couple of times until they reach the 4-11ma in standby point. Usually takes 1-3 resets.
Now, I'm not sure why this is all I know is it works. And yes, there is a huge amount of difference between 5+ and 50+ma.

I can surely confirm this

This is most definitely true, might sound illogical or fake but I personally took battery logs when my drain was 58mA but could not find anything, I changed Kernels just to observe the same and I finally gave up but I accidentally had to reset my phone a few times as I forgot to put it on charge/freeze then after a few days I happened to see terrific battery improvement 5-8mA, I didn't know why but then I understood it was because of the resets..

Good to see I'm not going crazy. Like I said, I tried this with a bunch of different ROMS. All the same.
So if you are having bat problems. Try a few resets and see how that works for you before giving up on the ROM.
Oh, I might also mention I am not running any sort of set cpu app.

Funny that just the both of us are populating this thread.. But yes I too do not use any Set CPU or Task Killers..
Currently on
Mattc Leo 1.8 with hastarins r7.6 with 5-7mA battery drain on Stand by (Wifi, GPS,Bluetooth off, data on(but disconnects sometimes))....

I can confirm this too.

Im a little new to Android on the HD2, running Mdeejay eVo Sense v. 2.3 rEVOlution 7.7 Hasteran at the moment.
Im finding the battery life on v2.3 less then on v.2.2 so I'll try a few resets & see if it improves, thanks.
Oh, is it really necessary to run SetCPU or a task killer?
Im forever closing tasks with task killer & the though of a task being auto closed when I turn the screen off is comforting, but is it best to just leave things to the kernal?

The most consistent way I have found to get 4-5ma on standby was to use exceller's android loader set autoboot android and 3 secs.

I can confirm this too.
I am trying dual boot (http://forum.xda-developers.com/showthread.php?t=723200) to boot into Android right away to see if that leads to more consistent standby battery drain. (this was mentioned on another thread.)
I have abandoned TaskKiller and AutoKiller, made no diff in battery drain for me.
I so still use SetCPU to slow the CPU when battery gets low.

For better battery life, setCPU is a MUST! Creating different profiles to change the cpu clock is huge in conserving battery; especially, the the screen off profile.
Ditch ATK and download Watchdog instead.

even hastarin himself is using android without setcpu. with kernels 7.6, 7.7 I get same batt juice as with setcpu, BUT less stuttering in general, i.e. android runs more smoothly.

Honestly I have found that every ROM I have used set cpu was a detriment to battery life.
I'm still not 100% that even task killer is helpful in some cases. I think that on the other hand has to do more with how you use your phone and what apps than anything. Some people can prob get away with it.

SetCPU is pretty much pointless now with the latest kernels, only thing it's useful for is overclocking, but even without it I've not found anything that can't run. Even graphically intensive games like Reckless Racing run perfectly fine at stock CPU speeds.
I've just updated last night to ShubCraft 2.0 DropMode and I get 6ma in standby, my battery dropped 9 percent in 8 hours of standby while I slept, and after a full day of using my phone from about 9am to 6pm tonight (texting, calls, wifi use, 3G use, picture taking, playing a few games and listening to over an hour of music) my battery only just hit 50% at 6pm. This is without SetCPU.

What i've done is just swap out the micro sd card for another one. I had the stock 16gb and replaced it with an 8gb micro sd card and i'm getting fantastic results.
Without any type of task killers or Set Cpu, i'm constantly getting 3ma - 9ma stand by readings from Current Widget.
I also downloaded Juice Plotter from the Market ( what a fantastic app IMO ) and it tells you how much time you have left on your battery as well as a graph detailing the percentage of power battery has used.
I can go a day to a day and a half with out charging my phone. I am in complete Android Heaven.
NOTE: Keep in mind that when booting into Android, when you hit the Haret, make sure that the hard key light are on.
I also have the auto sync off to save battery as well.

To get the 4-11 mA, just make sure the keypad lights on the phone are on when booting haret.(pretty much, boot asap)

After several reboots this is holding true.
Before when I making sure the keypad lights were on before booting Android I would still occasionally get bad standby drain, so I think that is myth.

Exceller's auto boot app = no battery drain!!!

GOLD!!!! PURE GOLD!!! Been trying to preach this for days now! The battery drain is eliminated by booting Android before WM/Sense fully boots. Has nothing to do with keypad lights being on or off. Hence, use Exceller's auto boot app set to boot 3 secs and restart your phone and let it auto boot. Battery drain ELIMINATED!!!!!

When you guys say do a few resets do you mean pull the battery or just use the off menu?

Just do a hot reset if your android buid has that option, even better power off and and reboot from windows

I'm using bangster v1.5 with hasterin 7.7. I only get 2-3 ma standby.
Sent from my HTC HD2 using XDA App

For me the problem was the SD card. I formatted it with 4098 (or similar)block size, copied the Android build back over the top and bang from 115-170mA to 4-9mA on standby!!! WOW.

method for fix HD2 SD android standby battery drain 50+ma

This method is suitable for hd2 SD Android, not test on NAND mode. If you encounter problems as the standby battery consumption(50+ma), you can try this method to solve:
If you reboot android and monitor the standby battery drain is 3~5ma,do not happy too early and think that you get a good android rom, because after reboot,it will likely become 50+ma;
If you reboot android and monitor the standby battery drain is more than 50ma, do not despair, don't think that this version is so bad and you need to replace another immediately, because you can use this method below to fix:
Steps:
1, reboot WM, don't hurry, wait 1 minute, let's WM fully reboot, especially some softwares installed on SD but need to run when reboot. press the power button to turn off screen(not shutdown mobile), open the back cover, remove the TF card, the screen will light up, tap the power button again to turn off the screen (not shutdown), wait 10 seconds, insert the tf card, the screen lights up again, now boot android and monitor standby battery consumption, 90% under 10ma ----- In short, that is, before boot android, pull out and plug in TF card;
2, if fail, you need pull out and plug in battery before reboot WM, then repeat the above steps;
If works, please say thanks
Don't charger when monitor standby battery drain, please use currentwidget monitor and use its log function to record. What is "the standby power consumption" pls consult Mr. Google.

Other users reported that changing the sd to another one solved the high drain in standby for them, so you basically are saying the same.
I use the original 2GB card the few times I decide to test android, because first time I tested superram build, my 16GB card got wiped for some unknown reason; I may as well see if your method changes anything.

Worked for me! Tnx!
Had 50+mA wen using android sd, very annoying because in the beginning I had no problems.
Now it's back on 8mA! Tnx!

Thanks
Thanks for the solution, seems to work every now and then when i get high drain on standby ^^ thanks

At first try, this seems to work well. I was getting 60+ ma usage in standby with Darkstone's SuperRAM build, even with a fresh install. Going through this little bit of voodoo got my standby usage down to the 5-8ma range. Thanks for finding this, though I don't like thinking about how much trial and error it took to discover.
I just hope I don't have to do this every time I reboot.
Thanks...

Was getting low power usage through this morning, when I unplugged the phone from the charger. I had left Android running on the phone overnight. I discovered that the HD2 was back to using 60ma when I got back to work. Repeated the magic spell, and I was back down to 8ma in standby. Really strange. Does anyone have any kind of explanation for this behavior?

Wow thx work like a charm.
imrazor - My theory is by pulling the SD card out in WM you stop all applications that use the SD and when you boot android the SD card is only used by android. Well thats what I think ^^
The point is it works and we now have better MA in standby.

Sort of works
The SD fix does take the standby drain to around 7mA, however I can only wake the phone once. The next time I try to power up, my phone never cuts on, and I have to pull the battery.

This is exactly what I am looking for. I will try it. Is it possible to write a program in WM to do this instead of pulling out SD Card?

That's an amazing solution.
If someone can tell me what to kill, I can try do create this nice prog...

Any idea why it works?

Didn work for me... Dont know did I do it right? I normaly shutdown my phone, do those things with the sd card (plug in plug out) and when I start android continuesly 50-70mA on stanby.. I did the battery thing and still the same...

Have MIUI SD ROM.
Current changed from time to time from 5-8mA to 50-70mA and back.
Killing all applications sometime give effect to decrease current.
Switching off autolight sensor sometime give effect to decrease current.
Sometime call in/call out give increase current.
Switching off in-pocket and near-ear sensors (call settings) give good effect to decrease current.
...
continue testiing
my head is overheat

switching on near-ear sensor after call return power consumption to 60-70mA.
switching off near-ear sensor not give decrease current.
call in/out not give effect.
sw on/off auto backlight not give effect.
sometime callout decrease current to 6-8mA,
but best result give system restart

Turn off HTC Sense

HD2 SD android standby battery drain 50+ma comes from 3 places:
1) What was running in Windows Mobile when you boot Android
2) The Android ROM you use
3) What is running in Android
1) The answer is turn off HTC Sense
When I turn off HTC Sense in Windows Mobile I get much better battery drain in Android. If I do not turn off HTC Sense then I usually get standby battery drain 50+ma. So flap can you create a nice prog to turn off HTC Sense etc. and then boot Android?
HTC Sense is not the only program. In addition to turning off Sense first, running a RAM cleaner (e.g. cleanRAM) in Windows Mobile will also help or - even better - reboot Windows Mobile without HTC Sense before launching Android.
2) use Portadroid to easily try different SD Android ROMs
3) see BetterBatteryStats

I started having this problem one day randomly (after i installed some new apps). However, even after i installed all the new updates and apps the problem persisted. I tried this method you mentioned and now my battery standby drainage is back to 7mA (instead of 30-60mA). Don't know how it works, but it solved my problem. I have since reinstalled the apps that I wanted and it has been working fine for 24hours...

thanks man

hi i just ask you what mean Tf Crad? SD card or SIM card

Hello, it doesn't work for my HTC Leo. I have battery drain 230-800 ma on the latest MIUI SD ROM. Any idea what should I do next? Maybe I must change the program, that measure the battery current? Now I'm using CurrentWidget.

Thank you, I will test it.

pssible soloution for battery darain on nand build

ii have been watching my new revived htc desire hd2(means hd2 which runs android) and i've tried a couple of nand builds and dozens of sd builds for the battery life
and here is the result
considering the fact that sd builds use sd cards to operate they use 2 times more battery than nand build
and now my battery lasts almost 2 days more in nand , while in sd builds i couldn't get a day through with it
but due to some rmnet connection problems most of people are experiencing high battery drain like 150ma
if u want to really compare the battery performance u have to put both builds on flight mod and the try them

I'm experiencing high battery drain running AD from NAND.
With: GSM + Data connection (no wifi, no BT), 55mA when idle
In the same configuration running from SD...5-6mA when idle.
Tried to disable data connection when running from NAND, result is 54mA...
I re-calibrate the battery, but still high battery drain...
Don't know where to look for as the NAND configuration regarding power management is exactly the same as when running from SD(screen auto-adjust on like from SD, screen timeout set to 30s like from SD)

could u give a little bit more information about your nand build and the radio
there is also a possibility that programs are struggling in the background
so you'd better try a clean build like nexus one

how to improve power consumption? in standby the phone has peaks 5ma to 50-60ma constantly! How can I do to improve the consumption?
i have MDJ FroYo Revolution v.2.2 [RMNET][kernel:MDJ S9.2 OC
Radio 2.14
I have read that some people do a certain procedure with battery and then obtain the optimization of consumption, you can say, or how to describe me?

Have a look on my sign
And regarding builds, both NAND and SD builds I used were Desire HD so it should be at least the same.

I followed the procedure:
-Charge the phone until full while the phone is totally off (shut down)
-Boot while the phone is plugged
-Delete the file batterystats.bin
-Unplugged the phone and wait until it is fully empty
-Reboot the phone to completely empty it
-Charge the phone until it's full
Done.

Im experienced high standby drain also. The only cure I found was to reboot the phone with the charger plugged in. If I just reboot it without plugging the charger, the battery drain stays about 50mA

ok look there are only two factors in the world that can cause battery drain
connection problem that is usually due to unsuitable radio and build
and background cpu involvement in applications that is caused by some applications
and it can be handled by task killer applications
except these two problems what really can cause battery drain?

I try and let you know, thanks!

In that final part:
-Charge the phone until it's full
Do I have to charge with phone off or on?

Am I missing something here? The title says "possible solution", but it's just a discussion about the fact that flight mode is the best way to compare SD and NAND consumption.
???

Have you tried the Radio drain fix?
- Enable gps+BT+WIFI
- Have a lock on GPS, wait for wifi and BT to go on
- Disable GPS+wifi+bt
This usually removes the 60ma drain, even if the GPS is off or has never been on.
>Most builds "forgot" to shut it off on start, but without showing the icon.

[Q] Screen off lag problem with [AUG12] AmeriCanAndroid AOSP HD2 GB2.3.5 CM7

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)?!

[Q] Battery life with NexusHD2-ICS-4.0.4-CM9-HWA V2.9a on SDCard

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.
