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!
Been trolling the forums, for a while, and I am wondering.. what effects battery life the most.. type of windows rom? the radio? kernal? or Android build?...

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.
Thanks to you! Follow your way, I now only 9mA with my stock rom. A considerable improvement in battery standby.
Thank you very much.

my phone tells me power in mV how does this equate to mA?

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:
su
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...)
im new so i cant post on rachs thread...anybody can help me with my battery problem on rach floyo v0.20...only 12 hours..is that normal?..
well I got the same problems with custom ROMs so it seems to be kinda common.

we can't answer you unless we know how much do you use your phone if you're not exploiting it at all, then it's bad, if you have your wifi turned on all the time (and other battery-draining stuff) then it's really good.
well i use the wifi on my way to work, a little bit at work, lunch break, and maybe an hour or two after work...i think its not that much..

I have tryed this app and the battery drain still the same. My batery is working for about 15h and I'm not using the phone a lot.

2% Fancy Widget
I think that it's a lot of batery on the display for only 47min
fine but that's very rough list...
did you tried dynamic view on processes & services & apps running - how much % of cpu time they consume? you can check details also with
- Spare parts
- System panel
- Astro file manager (Menu - Tools - Process Manager)
and last option is faulty battery.

Is it normal to have 5 Android System services??
5 x system could represents different services, so would not be afraid of that... more important for you is to see how much % of cpu time are they consuming at different time of day.
maybe apps like battery indicator could be more of help.

i wiped battery stats yesterday too after reaching 100% battery. And i saw in some place that now i should let phone battery go to 0%.
Strange thing is that since 8:00 my phone is with less than 25%, i have wireless, msn, skype, facebook, linkedin and some other random stuff turned on and atm i have 22& battery life.
Looks like my battery never gonna end today

I will try this too, since i feel that my battery-up-time is getting worse...
Hi I was thinking what if there was a way to manualy set the properties for the batterystats.bin file or if someone with really good battery life uploaded their battery stats file if we would end up getting the same battery life? I was going to give it a try but I can't seem to fine the values I need in the battery stats file soo...
Will someone that properly calibrated their battery or someone that gets amazing battery life upload their battery stats so I can try this and report back...maybe we can save us all valuable time by not needing to calibrate the battery every time we flash a rom! let's try it!

it depends on the Rom u are using....
For eg... I use CM7 and reaching a very great battery life but, I have flashed a new ernel (LordModUE 8.5), than I have flashed a PUV to undervolt the CPU. With No frills I set up the CPU in this way: 122 Mhz frq min and 1075 Mhz max freq...Ondemand Governor and VR like Script.
Than I leave only one mail on push and every widgets are upgraded when opened and not automatically.
Also the weather geo-localization is manually when opened.
Display light manually regulated on 15% and not on auto....
Display time on 30 second.
Sleep time set on 09.00 p.m. and wake up on 5.00 a.m..
When I sleep my device is in fly mode.
The Radio version is the latest with his relative RIL.
Good luck friend.....

look my signature
I would like to add: after flashing ROM fully discharge your battery and then recharge it. After that go to registry editor on your phone and go to
Code:
[B]HKLM/system/state/batteryux/MainIntervalIndex[/B]
and change the value from 6 (or any value it shows there) to 20...now press OK! You wil see that the battery level on top has been changed!
Now again edit it and go from 20 to 80 and press OK...
RESTART YOUR PHONE AND THEN CHARGE IT!
This helps me a lot. I used my phone about 37 hrs with calls, little use of BT and WiFi.
and then you don't need to do
- when battery drop to 50% (for example), restart phone... battery status be refreshed and show around 20% more battery level.... sometimes i restart 3-4 times phone before need to charge it....

haha, you are joking right?
where exactly did you look?
how about google 'hd2 windows 7 battery'
there are +3000000 hits and the first page has several links to xda here and also youtube videos to watch
this is a common problem for all these windows 7 roms.
the registry tips posted in below and also try the 'camera trick' which works for me
Planet O
well, the main trick is to discharge to 0 and than re-charge battery. My battery drain today is about 1% per hour. Battery consumption is very individually.
P.S. I installed hardware radio 2.12 and software radio 5.51. This cimbination is much better for me.
Hello,
i don't want to start new thread about my problem, so i pin here.
When i was thinking about to buy HD2 i didn't realize what i am going into, but now i have to continue.
Well everything is fine except damn powerdrain. It is normal to have on high usage 300-500 mA drain? Well i understand this usage when playing for example gta3 on nativeSD android, but seriously...?
Normal work drains my battery on android in 4 hours (NativeSD nexusHD2 - Wifi, exploring web, youtube, facebook etc) with about 150-300mA usage. Well i have to admit that currentwidget cannot show drain properly, but what it shows look really insane.
Also i found on WP7 more outrageous drain. I plugged in charger to HD2 and launched sims3. The battery was at 5%, but gaming made my battery dead. I had to buy external battery charger to apply some power, because battery was too weak to hang in boot time.
My primary questions:
1. Is this high drain normal?
2. Is 80mA charging power normal (using HTC charger)?
3. If i flash android to nand, will power consumpion on high usage be less?
