[Q] Very High Power Consumption Android On HD2

Hi,
Ive recently installed Android 2.2 Froyo on an SD card on my HD2 and the battery is going down so quick... it wasnt great in Windows mobile but now I'm struggling to get it to last all day...
I'm saying to myself this cant be normal, I'm also trying a Samsung Galaxy S and the battery is so much better!!
Is there anyway I can improve the battery power on my HD2, I know in a HD2 the battery is a 1350mah and the Galaxy S is a 1500mah battery.
Should that make such a difference?
I'm considering going back to Win Mobile but dont really want to but havent got any other choice if the battery carrys on like this....
I also notice the screen and back get really quite warm... I suppose Android is making the system work harder?!?!?!

Its safe to say that you havent read any of the threads about battery life.
Before you say I did a search and didnt find anything Ive already typed in battery in search and found a bunch of threads.
Now what you need to do is find out why its running so warm.
It could be the kernal version you are using.
Ways to improve battery life are using setcpu and underclocking. A lot of members use current widget as a method to see when High drain is occuring.
In sleep mode you should be seeing less than 10ma. If you dont see less then this there is a problem.
Set current widget to 1 min intervals.
Dont use task killers they dont help anything no matter what anyone says.
Dont compare the captivate to the hd2. 2 different phones.

I am using mccm 1.5 customize, and CurrentWidget shows 5mA on standby which I think is good enough. Sometimes, it shows 60mA on standby in a while and my battery drains very fast, even I use Advanced Task Killer but it does not help. I have to reboot the phone to get it back to 5mA on standby.
Anyone has any idea of what may cause my standby power that high (60mA)?
Thanks.

Thanks for your tips for better battery life. I was curious about a few things and hope you could clarify a few things for me and some instruction or threads on how to do so. And yes I have searched, that's the first thing I always do before I do anything web based as far as positng.
1. How do you setcpu and underclocking?
2. How do you find the amount of battery that standby takes? i.e. 60mA? How do you get to that setting in android?
Thanks for your help in advance.

Setcpu is an app used to control your cpu speed.

To check ma's use (current widget)
http://forum.xda-developers.com/showthread.php?t=776085
long press on the desktop and apply current widget. It will ask you if you want to create a log. Create a log for 1 min intervals. Put the phone to sleep and leave it for a good 5 mins.
You can then open the log file usint astro file manager and check your drainage while sleep.
One thing I found is that If i am having high drain i turn my gps on and restart then it usually settles down and I can turn the gps off.
If you have apps that are syncing you will a higher than normal drain during those times the apps sync. if you set your apps to sync at longer intervals the amount of batter drain will be unnoticable.
I have major battery ocd. I constantly check my battery and have to force myself not to look but still use my phone as any normal person would.
I can pull more than 12 hours easy!

Thanks hazard99!
The first time I ran android I don't think I've had any battery issues and now that I'm looking at the percent on my homescreen Im beginning to feel battery OCD too. It's like I lose 1% atleast every 15 minutes when I look at my screen. But I did take and apply all the tips you told me and I do see that it only uses 5ma when screen is off. I truely don't understand. :/

Stop looking at your screen. Stop worrying. The more you look the more juice you use while the screen is on. There will be more points where the phone is off.

Ive also been trying to investigate this, my standby drain is usually 60+ mA, and during use it jumps to the 200's, strange stuff indeed....For you to have 5mA, lol i wish that was for me too =/

What radio and wm are you using? Do you use SetCPU?

I had high battery consumption, too. But now I found something interesting...
Due I'm not allowed to post links, yet, search for the post with topic:
[SOLUTION] Possible solution for heavy battery drainage.
With this fix: over night I only lost 20% instead of 59% of battery.

uninstall SetCPU

im using the same radio as you (2.10), energycookie rom 21916, and my setcpu is at interactive 245/729, and for sleep its at 245/384, hastarin kernal.

Use a Battdrv.dll from older HD2 ROM 1.48 Etc. I'm not sure if you recmod the module and replace the current one in Windows if you will get the same benefit as if you cooked the driver in.

i just updated my kernal to the latest zimage in mattc's froyosense's evo tree, and my standby is around 6-11 ma now, guess that solved some issues lol, anyone know whats the normal operating ma power consumption for texting?
EDIT: Now when i try to enable wifi i simply get "error", did i mess up on something? =/
EDIT: Solved above problem. WOOT!

[Q] Battery Life Changing

I always had the issue of battery life being short as hell, 60ma on standby
i even updated my radio to 2.14* the newest one forgot the name but no luck!
But recently i got good battery life 5ma on standby!!! After i flashed the newest ChuckyRom Lite Rom.
But yesterday it went back to sucking again after i restarted android. i restarted android before, but the thing i did different this time was have the charger plugged in when i booted into android.
So my question is to the people that have excellent android battery life, How do u boot into android? Do you Flash a new rom? Format your memory card? Do you use set cpu? ATK autokill?

I can easily go a day on one charge. And normally I boot into Android while charging. I don't think it matters tho cuz you have to unplug and replug your charger cable before android recognizes it. I'm running Kumars GTX and have a class 6 micro SD (helps with battery life). I also use set CPU and have a taskiller icon I normally press before I turn my screen off. Also I have 2.12_5 radio and had worse battery with 2.14. Hope this helps,

Lose the Taskiller icon, it does nothing but harm. First of all it uses extra battery, because most apps you kill will simply re-open quite shortly after, and secondly it may slow down your phone, or generate problems. Android works in a completely different way than Win(Mo/dows), here it's not a good thing to clear up ram.
The only occasion in which you should use a taskiller, is when an app goes mental and you need to shut it down somehow. For all other cases, don't use it. That's not my personal preference, but a fact that all Android-savvy people will confirm.

For me it sucks the battery out when I just use android
Standby I get 8-14mA, once I use some apps for few minutes it jumps up to 150-400mA :S
What can be the cause?

winmo IS NOT running in the background! android is not emulated or s.th. like that.

well maybe it has to do with usa hd2 or euro hd2? i have the usa version
its just realllllly odd that the battery varies sooo much from person to other
i have tried countless things to improve battery, search far and wide in these forums, but no luck.
and when i dont do a thing it does well at 6ma but then all of a sudden it raises to 60ma on standby, when i restart. (60ma is what i always get)
i even got the new sd card from htc free but no luck and its a samsung! (im pretty sure samsung is more reliable, no?)
MAYBE A FILE GETS CORRUPTED that has to do with power management?
just throwing ideas around, anyone have any other theories?

I recently was able to get better battery life, this is my setup
8 gig class 6 microsd
Radio: 2.10_50
WinMO Rom: ChuckyRoom-Tabtastic lite (Put in AIRPLANE MODE before booting Android)
Android: mDeejay froyo Z 1.3 rev.
I am not using setCpu, but I DO USE Taskiller
With this set up I am getting 4-7 mA drain in standby

My tips for battery life are in the FAQ in my sig.

[Q] Battery Issues;BSOD/SOD;EBL?

So, I'm at a loss of what to do here. No matter what settings I seem to use I can't get good/decent battery life.
In fact, I get terrible battery life. With light to moderate usage I have to charge my phone at least two times a day, mostly three. Current widget reads that at standby I'm anywhere between 55mA-70mA and when in use 200mA-500mA. When charging it reaches 400mA-600mA
I see everyone talking about being able to get 5-10mA and I'm amazed at this. I've searched and read most "Battery saver" threads and none of it seems to work.
I was originally using Chucky rom lite and when I noticed the drain was abnormal I switched to the set up that chiasoft uses in his ReadMe for the ROM (stock 2.10ROM/2.08 radio).
Although since switching to the stock WinMo ROM I had repeated BSOD and SOD issues. To the point that it became unusable. I switched over to latest Energy ROM.I installed EBL and on both Stock and this Energy ROM. I am still having BSOD/SOD problems. Could it be the EBL? I plan on upgrading the radio to 2.12 in a few after I test out this EBL theory.
My setup as of this post is this:
WinMo ROM: Energy.BLACKSTONE.21916.Sense2.5.Nov.08 (Switched back to Stock 2.10)
Radio: 2.08.50.08_2 (Switched to 2.12)
Android: MooMoo Froyostone Sense 3.2 w/hastrain kernel
SetCPU:
998max/245min Ondemand on boot
Profiles: Screen off; Priority 100; 384max/245min ondemand
Battery <25% 576max/245min Priority 0 ondemand
Sampling 20000; Up Threshold 40
Advanced Task Killer:
Kill Level Agressive
I really don't want my LI-ON battery to die before I've even had the phone for the year. So if anyone can think of anything to help I'd be ever so grateful.
And of course, thanks to all the people who make all this possible.
(Sorry for the tl;dr post. I wanted to give as much info as possible.)

when you fully charge your batter what is your mV ? use the battery life widget to determine this. If it is not nowhere 4000mV once fully charged, you might need to consider buying a replacement battery.
btw. my mA reading is actually worst than yours. Might have to calibrate the battery again later.

idk what it is fully charged. I'll be sure to check it later though. How do you calibrate the battery?
Also, I realized that I made an oversight on my part. When I switched to the stock WinMo rom I hadn't realized fully that it changed my Radio to 2.08 even though I posted it.
The rom chef recommends 2.10ROM/2.12 Radio, so that's what I switched to to check out that combination.

btw change it to interactive not on demand.
you charge the battery when your phone is off. Till your charge indicator turns green.
Once that is off. you can use root explorer or adb and go to rm/data/system delete the batterystats.bin leave your phone plugged in while you are deleting the batterystats.bin file
i prefer root explorer. but its not free and your device has to be rooted.
let the phone drain the battery till its dead and turn it on again to make sure it is completely dead.
charge the phone like you would usually afterwards.

Yeah. No interactive settings. Also, that guide recommends 1190 max, but mine only goes up to 998.
Also, I finally got it to down to 7mA in standby. When I changed the radio to 2.12 and using a 2.10 stock WinMo rom.

no issues here getting 48 hours of light use, or a full 24 of moderate use...

I've yet to "condition" my battery. I'm worried it'll do more harm than good. Especially since I just got it finally to a decent mA draw. Although I'm worried my phone won't charge up to 100%. Always stop at 95.
Is conditioning really necessary/important?

easy answer... whats your full charge voltage? shuld be 4.2
if not , your looseing batt life..

yes full charge voltage should be around 4.2. Try charging it with the phone OFF till your charge indicator is green. This way you can achieve a full charge.
By the way how the hell are you getting 48 hours on light usage?? excuse my language. What are your setcpu settings, configurations. etc.

Yeah, 48 hours seems improbable. I finally got it down to 7-10mA on standby, and I think it charges up to 4.2 but I'll find out for sure tonight.

same
I had the same problem, make sure you use EBL android launcher and set to autoboot at 3 seconds. Make sure you restart your phone anytime youw ant to load android. I assure you this will work.

My HD2, like all others can be flattened in 2-3 hours with windows/android if used hard, the difference seems to be on very light usage/standby win mobile could last 4 days... with everything turned off and basically not used Android would struggle to last 2 days !
Same phone same network/signal levels etc, can only be poor power management within Android, and I think that means voltages for all the processor and comms modules, not just a simple case of turning down speeds.
What do others think ?

Update: Upon switching to WinMo:2.10 and Radio:2.12+ MooMoo's MMS fixed froystone3.2 I was achieving 6-10mA in standby. The phone would last all day with a two-three hour charging period with moderate usage. Low battery use, rare DC's. Perfect. Best build I've used so far.
I'm noticing a new problem however, and I wonder if it's happened to Chiasoft who recommended this build. I'm getting serious touch screen freezes since last night. Anytime before that the set up was working AMAZINGLY.
Now? It's almost unusable sometimes. This morning it was happening in Android so I switched to WinMo and surprisingly enough it happened in there too. So I read touch freezes are Radio problems mostly. Is this true? Should I switch to a new radio? I'm confused as to why it would just randomly start happening though and worried it would mess up my battery troubles I just solved.
Any advice?

Hmm. I noticed that it almost always freezes when I hold down the end home button to turn off the phone or data or to silence it. I can't actually use the touch screen again until I hit the button again to put it to sleep.
I wonder if it's hardware related because it was happening in WinMo that way as well.

Okay, so now the entire adroid system is acting up mostly related to the touchscreen. Like I use the calculator and it appears that i'm holding a button down. Or I try to make a call and it's not responding. It appears that when I hit end call button repeatedly it allows me to unlock the phone. But when holding down the end call button to get to the Power Off screen nothing in that menu is responsive.
It seems... software related, but I'm not sure. Any info would be helpful. I'm going to reformat my card and reinstall droid and see what happens.
So, called t-mobile. They're sending me a new replacer phone. Oh well. We'll see how that one goes.

I give you only a very short suggestion
You have just to DELETE SETCPU
and delete ANY TASK KILLER (you can keep it just to close any apps that could hang, but not to "free up ram")
Android is not Windows, you dont need to free up ram, and you dont need to overclock/undervolt to gain some minutes of battlife despite stability.
Talk to any Dev and they will confirm this.
Good Luck

What effects Battery the most?

Operating system? Screen colors? Flashlight for movies or photos?
Battery - energy loss or charge? Age - recycles from deep discharge? Plugged for longer than needed? Air temperature or silicon cased? Temperature with heavy energy drain?
Not a simple question.

As far as software goes, the biggest killers of battery I've noticed have been push notifications and wifi. Turning both of them off almost doubled my battery life. I now have my emails synched every 10 or 15 minutes instead.

In addition to wifi and push, a big one maybe the biggest, which is often overlooked, is screen brightness. These big giant screens burn a lot of battery. Keeping it as dim as you can stand it will actually save quite a fair share of battery

I feel silly for not mentioning that one myself now

heres a funny thing i found, i replaced my Apacer 8GB Class 4 card with a Sony 8GB class 4 card. the phone use to hang with the apacer card.
the thing is, ever since i´ve made the change, the phone sucks up twice as much power.

Theres great ways to make your battery last here too:

Calibrating Android's battery read will allow Android to fully charge your battery, and if you have battery profiles in setcpu, then the app will scale your processor speed by a more accurate reading, giving you longer battery life. I did it on the couple of builds I use most, and it really does make a difference
And dont feel silly john, I sometimes take my enormous screen for granted too
Edit: hmmm maybe my class 2 is why i get good battery life, maybe a slower r/w speed sucks less juice?

well, i know all of the normal tricks.. like screen brightness, wifi off, email push...
i am just looking for a windows rom, a radio, and an android rom, to get the best battery life...
thanks again guys.

Have a look at my signature.
Data enabled, push every hour only 5mA in standby.
If it is in airplane mode it only uses 2mA most of the time. That's quiet good

From what I can tell, the single most important factor for better battery life is using an auto boot app, such as Exceller's, to boot into Android soon as possible. I set mine to auto boot in 3sec. If you let WM/Sense boot fully, you will experience higher than normal battery drain; around 60-70 mA drain in standby. Also, try installing Advanced Configuration Tool in WM and enable all options under Power Management. Have tried these techniques with pretty much every WM Rom and Android combo and average around 3-9 mA draw in standby with wifi, sync, gps and data all enabled. This translates to about a day and a half of moderate use for me. Also, remember that Sense builds tend to use slightly more battery than non-sense builds.

This method really works! The simplest way!

I have trying different things for some times as why my HD2 was always 60mA+ power drain but some others reported as low as 5mA in standby mode. I tried different builds and different settings but none worked. I almost want to flash to change my stock rom or give up the idea of using Android.

It doesn't really, mV is a measure of state (what condition your battery is in), mA is a measure of change (how much power is currently leaving/entering your battery).
Download current widget, free from market, to track the current (= in mA)

Current Widget. Set it to update every 60 secs, and then leave your screen off for more than 60 secs, turn the screen back on, and check the widget.
Battery drain with screen off should be somewhere between 5-9 mA

Nice tips here guys...
My battery meter in the status bar looks about 60-70% full, but battery widgets say i have about 50%.
Does this mean that I need to calibrate?
I tried to delete the battery stats with Droid Explorer but it seems to be in read only? (It doesnt do anything when i click delete).
I guess I'll set up ADB and delete that way.
Also I seem to get better battery without LED me know, (why do i need this?)

Just run terminal emulator on your phone and type:

rm /data/system/batterystats.bin

oh, you can do this on the phone.
Thanks bro!
I hope to see improvements as my theory that the status bar battery reading vs widget battery reading being so different = it needs calibration.
Edit
I am now using Exceller's auto boot, and the my draw peaks are waaay lower, but the idle has gone up! (60-80 now...)

Device RAM = 410MB?

I have run a few NativeSD ROM and all says around 410MB RAM. What happens to the other ~ 150MB ? Is it the amount of the ROM loaded into RAM? If it was the case, would I get full 570MB when installing on NAND? Thanks

As far as i know some RAM is reserved for the Adreno 200. ( The GPU.)

There's a breakdown of RAM usage in the post I linked, which shows why only 411MB is available to use.

I think vbulletin should have added those tags long ago!

It's worryingly sad how happy I would be if they did that :')

@ Nigeldg: that s why you are a recognized contributor :good:
@Nigeldg & NYLimited : I see you both running JB 4.1.2 from tytung, what is your device battery life esp. at standby like during your sleep, how many % the phone drains? Mine could drain 20% for 8 hours , and 50-70% easily for 24hrs with stock ROM, mobile/wifi off . This time i did search and seems like there are a few people have the same experience but no solution found.

As a little background, I use Kaiten mail which is connected to 4 or more email systems via the IDLE protocol at any given time and downloads new mail, usually within 5 seconds of arrival. I update weather every 3 hours and Google runs who knows when to check calendar, contact and play store updates.
Having said that, I do use Tasker which turns off my data connection for 7 hours while I sleep. I do run a scheduled Titanium Backup each night while data is off. During this time (remember, no screen and no data) the device uses about 6% of the battery.
During the day when data is resumed it will use about 25-40% in 12 hours depending on things like mail volume. This is without the screen turning on!
I seldom have wifi on when not plugged in. Tasker does, however, automatically turn on wifi for me when at home and plugged in.
When I am using it (reads screen is on) all bets are off. Luckily, I am usually near a charger.
I also purchased a Powerskin which is a second battery that can piggyback on the device giving me two connected batteries at the same time, essentially doubling my capacity.

6% for 7 hours while you re sleeping seems normal . Again, mine is around 20% for 7-8hours ; that is unacceptable but I cant find any solution. You dont have any special kernel or governor, do u ? Mine is just the built in with tytung 1.3a and smartassV2 .. I really like the ROM but cant live with the battery life.
PS: saw you reply on the other thread..I am gonna try fsck first and do NAND install to see if it make any diff from NativeSD

Could you give a value in mA using CurrentWidget? It should be between 3-5mA most of the time in standby, occasionally jumping to 10 or so when syncing stuff. Also check the drain when in airplane mode, which will help determine whether it's one of your connections that's causing the issue. In airplane mode drain should be a consistent 2mA. If you find the drain to be quite high e.g. 60mA, try the solution in this thread, it used to work for SD and may still work for NativeSD.

Stock kernel but I do occasionally switch governors to see if it makes a difference. I am currently using "interactivex" (governor) and "deadline" (scheduler). While they do make a performance and power consumption impact I am not sure if it is significant.
Checking logs can sometimes pinpoint culprits and, of course, the one none of us like - starting over clean and installing one app every few days to see which will trigger it. (shudder)
BTW, I am running DataOnExt, not a pure NAND install.
