If you're running Android on your HD2, then battery will last about half of what it lasted with WM. If you take a Desire device, its battery life will be at least double than a HD2 running Android (proving that it's not a fault with Android itself).
When the question is raised of why Android kills the HD2 battery so fast, the usual answer is: "Android for HD2 is still in its infancy stages".
The question is, do anyone has any clue why in this "infancy stages", battery performance is so poor ?, I mean, if you want to solve a problem, you first need to understand what causes the problem, and I don't think anyone understands why battery life is so poor, so why should we assume there will be any progress in this regard in future builds ?
I do believe that developers will probably be able to activate every feature of the HD2, simply because we understand why some features don't work now (for example: maybe we don't have an appropriate driver). Battery performance, on the other hand, seems to be a much more mystical feature, nobody understand exactly why the performance is poor, or what is needed to be done to improve it...

What ???, that's the only (or even main) reason ???, the power requirments of the SD card are so much greater than that of the internal storage ?
Many people are reporting poor battery performance even in standby. Is the SD card active in standby too ?

Thanks for the tip, but you are not answering my question. In WM, data is not off when the screen is off, yet battery performance is good. With the Desire device, data too is not off when the screen is off, and battery performance is good too.

Actually Mystik610 already told you the problem. Yes, running Android from the SD card is the problem with battery performance.

Is the system running in standby? Obviously that it is, so the SD card is active also in standby. Equation solved.
Form what I understand it's because cpu scaling isn't fully functional yet... That's why the bottom of the device gets so hot when in use with android. That, along with the SD card and data (witch isn't 100% optimized yet) is why.
these settings worked for me in improving battery life

now with froyostone v1 I lose in standby around 1%/hour...in WM I lose 0.5%/hour
with setcpu set correctly (+the 925mV kernel) and those power management registry tweaks I'm able to do 2 and a half days with my phone, including usage like a few calls, a bit of browsing every day, about 4h of music and downloading mails four times a day.
Thats pretty impressive for me, don't remember getting much more or even more in WinMo.
I could say that SD card is not the only reason. I used Android-based devices (Liquid and Desire) for a while and I can say that android has slight problems with power management itself.

I was under the impression that in standby, the parts of the system still active, run from memory (RAM), and not storage.

Something here doesn't make sense. If the main (and surely if only) reason for poor battery performance is because the system works from the SD Card, then why people offer SetCPU as a solution ?, if SetCPU can solve even part of the problem, it means that Android CPU scaling abilities are not working correctly with the HD2 builds. Am I wrong ?
Do people with the Desire device also get the same boost in battery performance after using SetCPU, as the people with the HD2 device ?
I've not noticed any difference in battery consumption using Android over WM.

I can confirm that SetCpu is vital for the Acer Liquid E. My girlfriend has one and I had to flash Liquid Community Rom with SetCpu due to power consumption.

You should try the tip posted in the other thread
http://forum.xda-developers.com/showpost.php?p=7764579&postcount=11
SD cards vary in class and power consumption. Get and try a class 2 card and you will see the difference. The latest cards are power hungry even in standby. I asked this question of Sandisk and I was told that the info is only available to devs!!!
It causes the problem with Winnow usage as well especially when you install any apps to the higher class of card.
Using a class two I get a day with heavy usage. Right now after 8 hours I have 60% left.

so, we may assume that if we nand flash android rom we can get better battery and performance, sorry for not reading lately this forum but is there flashable android rom for ANY ex-winmobile htc device and how this compares in battery performance with android roms running using haret.exe?
Question for all GB users, which is a pretty high number here. I ran MIUI Lithium and loved it except the battery was pathetic. I can deal with generally bad battery life since i came from an HD7 but it got out of hand. Anyway since there are a lot of GB roms out there and pretty active i suppose a lot of u found a way to handle it better. How do you u GB users get the most out of battery on a GB ROM? (ROM, Kernel, tweaks, etc.)
please share your setup since it can help a lot of others that want to manage battery better

Try using the Bali-CM (For CM7/MIUI/OMFGB) kernel. It was designed around improving battery. I'm currently not using it however when I did I had much better battery life when I was... Also remember to undervolt, as that should further increase battery life without loss of performance. "Screen off" profiles in overclock apps like SetCPU also help in battery conservation.
An app that really helps battery life is called Juice Defender Plus. You should try it out! Here's an overview of the app posted by "Woodrube" that should help you get started...
This is how the JD Plus works (no need for JD Ultimate b/c we don't have many of the functions it supports. I just copied this from another thread the OP started awhile ago and I was trying to helps him out there.
If you set it to custom, the go into the settings tab on the right and then all the way at the bottom, there is two buttons to push, The first in Interactive which will pull up Juice Defender for up for any app that isn't already configured and the other is Configure Apps. This is the one that you can customize on an app-to-app basis where if you are no using an app and the screen is locked, it kills the radio/data traffic for that app.
Say you are listening to IHeartRadio, this you would want either Enable or Enable/off (which means the screen will be locked but the radio/data will be working). Now take the browser. It you are not using the browser, then you don't need it transmitting data right? So you would set that one to Enable (which means that it will only enable data traffic when that app is being used).
Juice Defender only works when the screen is locked, don't forget and all widgets are battery drains b/c all they really are is a monitoring app and if it is tied to something like FB or G+, then that data will be running constantly.
Examples:
Gmail = Enable (not enable/off b/c then it will keep your radio/data open)
Beautiful Widgets = Enable/off
mClock/Clockr = Enable/off
Angry Birds = Disable (with this and something like Adfree, no more ads in Angry Birds even though the ads are embedded in the .apk)
SMS/MMS = Enable or Do Nothing (why would you push disable)
Enable = Radio/data on when app is in use (front)
Enable/off = Radio/data on for background apps (when screen is locked)
Disable = Disables radio/data traffic completely when that app is running
Do Nothing = What is says.
I have been using JD+ for over a year on 3 different phones and have noticed a considerable difference in battery life, even on a crappy Motorola phone. Just takes some time to figure out YOUR settings and what YOU like. I have also used it on Stock kernel and had no problems either.

Also, don't forget that our Vibrant's screens are huge power drainers. Keeping it on a lower brightness level helps save a lot of battery. Hope this helps!

By the way, whenever you flash a new rom you are going to want to do a battery re-calibration. This will help excessive battery drain. However you only need to do it once when you flash a new rom! Use this app to easily do a re-calibration.... http://www.google.com/search?gcx=c&sourceid=chrome&ie=UTF-8&q=battery+calibration+nema
Here are some screenies to give you an idea of how JD+ can be set up. Noob, thanks for the tag, buddy.
+1 on the screen settings too. Plus when you are pulling on-line music for extended time and notice the phone getting hot, it isn't all the processor, it is the screen that is causing some of the heat. Hence my enable/off for MLB or Tune-in in the shots below.

No problem, bro.
Which version of Lithium were you running? Try Prime 360 (Miui 2.3.7). With heavy usage, I usually get around 16-20 hrs. With light usage, I had 29hrs with it. Let your battery drain, fully recharge and you should have remarkable results.
I tried NB-360 ROM, it had decent battery life, with many battery saving features included, but it didn't compare to Prime if you need longevity out of your battery. It currently uses the Neo R18 Kernel.
Let me know how it goes.

So my Setup is basically running CM7 (with 2.3.7), and having a kernel which supports something called "undervolting"
right now, I have a kernel called glitch kernel.. which basically gives me an app where i can set my own custom voltages (like undervolting it -50 mv from the original voltage). THis can help save TONS of battery, but always refer to your kernel guide on how low to set the voltage.
We don't want any bootloops or bricks now do we
I also use an app (in conjunction with my kernel) called screen filter. This dims the LEDS inside youe phone individually so it saves a ton of battery.
i get 1.5 days on full charge listening to music and going on the internet constantly
thanks a million guys. im currently running cm7 stable and flashed glitch v13 kernel. set leakage to medium (honestly still dont understand the difference very well) and undervolted like you guys recommended. ill see how battery treats me.
^^ BTW i had Lithium 11/11/11 update with default kernel
If i see a significant increase in battery, ill give MIUI a go again with Prime since it seems to have good battery. Ill keep u updated, thanks again
Edit: quick question. is it true that the solid white colors still kill much more battery with our screens? or was it mostly a first gen amoled issue?
Sent from my SGH-T959 using xda premium
update: glitch v13 with undervolting really did the trick!!! after a full work day on which on a GB rom my phone would be begging for mercy with about 20% remaining more or less, today i finished with just over 70%, and that was after i realized that the undervolting settings did not stick after boot when i unplugged it and i applied it again (my phone was at 90% when i did this)

I haven't been using stock ROMs for a while, and am now currently on AOKP JB, which is awesome. But I've recently had the need to be out of the house for an extended period of time, and i really need a ROM with good battery life.
So quick question, which GSM (or CDMA with GSM-patch) ROM gives the best battery life? I'm more inclined to think stock, and I've read that 676.226.3.en.EU gives really decent battery life. Or is there a better alternative?

Ive been using the simplex rom it has overclock and underclock scripts built in I have been on it for a few days and got 5hrs of screen on and 19hrs of power overclocked with 25% battery still left. Currently I am running underclocked to 1.0 GHZ to see how long Battery will last and sitting at 13hrs on battery and 4.5hrs screen on time and have 44% battery I think I'm doing well!!! No bugs yet either!!
SimpleX is for CDMA right? My bad, I should have specified that I was using a GSM phone.

i'm using magicmod rom, coupled with tasker to turn on 3g only when using data intensive apps like browser,youtube etc.. the rest of the time i have data enabled but 2g, and the battery only goes down about 2-3% a night, that's about 2-3% for 8 hours..

A couple of things...
Is everything working?
And of course the famous "is wifi tether working"?
And - how stock is stock? Do you get the horrible message in your pull down, "There are wifi networks available?", "Your wifi is off" blah blah blah. Man! That was irritating!

Sorry but no zip rom dev will ever improve battery life without coding their own battery saving applications.
I am sure the rom is great, but don't credit battery life to it
Short of going to AOSP, you cannot significantly change battery life on any ROM compared to what it is based off of. So, if you make a ROM based on Stock TouchWiz, it is going to get approximately the same usage as the Stock ROM. If you have doubts, go do a comparison test. Even undervolting isn't going to do anything significant for you with modern day processors.

It has always been my belief that you use roms for features, not performance or battery claims.
I use Jelly Beans ROM 8 and the performance and battery life is 100 times difference. The battery with heavy usage was at 56% from 7am until 5pm. My Galaxy Note 2's performance without overclocking has been extremely fast in comparison to stock, I can now watch videos with any browser without the hour glass circle hanging for an extended period of time.

AOSP based ROM's can get you better performance and improve battery life (though I very rarely if have ever actually see the later).. At this time there are still issues with AOSP here and there.. most notably the gpu has either glitches or a memory leak (one or the other) and bluetooth is sketchy.
Zip ROM's or Stock ROMS will not change either performance or battery life by any real significance.

I disagree. Lol. I'm not a dev and don't know how to code (sure I'll get flamed) but here's how I see it:
"Debloating" does save my battery a bit. Some crap programs running in the background (at all times) that I never use, showing up in my battery stats and my running apps using xyz of my ram, apps that I *never* use (I mean NEVER opened) -- you don't think killing those (in effect - killing process) has any positive effect on ones battery life?
I think it does. I've tested it. One example: anything exchange related on this phone and the Note 2. Also: smart alarm clock. That damn widget never sleeps and I've never used it. My phone sleeps better without it and I do believe overall (with the other rogue apps I kill) my battery is better.
I'm ready to be proven wrong.

I don't notice as much now, but with older devices bloat had a huge impact on performance and battery life. On some of my phones blockbuster was one of the biggest battery hogs and I've never once opened that app. On my Droid X with 512mb ram it would start to lag at 90mb free, it was really bad once it got down to 70mb free, and would freeze at 50mb free. Before I first rooted I had to use a app killer before I used my phone so it wouldn't lag, and if I used it more than 20 minutes or so I had to run it again to stop the lag. Once I rooted I started using an app to set the memory to always keep 90 mb or more free and didn't have lag anymore, but the apps I was using would constantly redraw but bloat apps I never used would be eating up all my ram, I debloated it and have been fine ever since.

Those *things* you never used are backgrounded and harmless, despite perceptions.
I have never seen a battery use screen shot chock full of apps never used draining the battery. ...
Except Maps. That one is annoying.
I am fully stock still and almost 2d usage with 34 percent left.
This is with Scott's clean Rom 1.0. Maybe stock gives you the same battery performance. But this Rom is as smooth as butter.

Slick V3 plus MEs kernel. Lower min clock speed and use badass governor. I've never had anything better. I'm currently using MEs EG8 ROM, which I like better, but battery life is slightly less then when I used Slick.

Best configuration for extended battery life = power off when not in active use.
Not trying to be a jerk here, but while stating that question is simple, the answer most certainly isn't. There are a huge number of factors that play into battery life, and you haven't provided any info at all to us to provide good answer.
The answer depends on how you use the device. Do you need extended idle time but not high performance? underclock, undervolt, freeze all your background apps. Do you have lots of stuff running in the background? Try greenify paid with xposed features. Do you want the most possible screen on time? drop your brightness as low as you can stand it. Run in Airplane mode. Are you in a crappy service area? Turn off cell radio and use Wifi only.
We don't know what you need for connectivity, or how you use the device, or what apps you run, or anything else. We need tons more info to try to chase battery life. We don't know what will constitute "acceptable" performance, to you, when down-tuning processor speeds and brightness and things. These are all things you need to experiment with to find what works best for you.
In general, I've found that for my use-case, the new 4.3 ROMs are marginally better on battery life than prior versions. I typically get about 4 hours screen on time, with around 20 hours up-time, and minimal phone calls (15min per day or so) and end up having 15-20% battery left when I put the phone on the charger. In moderate use, I look for wakelocks to be roughly twice my screen on time. I don't run much processor intensive stuff, the majority of my awake time is spent at minimum clock speed.
Min screen brightness

Min screen brightness, lower timeout, eco mode, task killer, data off and airplane mode at the office (or school or whenever you use "silent mode" instead)

Be very careful with task killers. If you try to kill stuff that auto restarts, you will end up causing battery draining start / kill loops. In general task killers haven't been necessary since gingerbread.

As stated before, the 4.3 roms seem to have better battery life then the previous versions.
Certain apps can help with battery life as well. "Tasker" can be setup to disable functions when not needed.
"SetCPU" can be used to setup profiles to change min/max frequencies and change governors when certain conditions are met... this can also be done with Tasker but requires a good understanding of Tasker functions.
"Greenify" is also a good app. It will hibernate apps that you choose. This can prevent certain apps from running in the backround until you actually use them.

Kernel Confusion
Dear Concern,
m using AT&T LG Optimus G (e970), i just rooted my phone and unlocked my bootloader. the confusion m having ritenow is
m about to install the new custom rom in my phone but m confused about the kernel thing that ppl used to talk here .. my current software information is
Android Version :: 4.1.2
Kernel Version ::: 3.4.0
Software Version : E97020J
Can anyone guide me if i need to flash kernel while installing the custom roms *4.4.2*, and what are the risks?
is it necessary to flash kernel or not ??
Regards.
Moiz
Its not necessary to flash separate kernel..custom ROMs come with embedded kernels sometimes modified from existing kernels,such as mizry's AK kernel...flashing separate kernels are optional
