Battery life

Hey guys, new to the forum and stuff so take it easy on me. Just wondering, I'm running android from my SD card in a hd2, will that make my battery run down faster?

In short-yes it will.
In long-power management under Android is not as advanced as WinMo, so your battery will last 7-8 hours on a charge with moderate use...even less with data or Wi-Fi or the like.

So it is the android os and not the fact that I'm running an open file from the SD?

Running it from the SD card makes no difference as far as power is concerned, as it's just flash memory, and really no different from the internal NAND of the HD2. Android devices historically have pretty bad battery life, because the underlying Linux kernel isn't really all that optomized for mobile devices..though that is all set to change with a future update in the Froyo code.

In my battery usage it says that the display is using most of the battery, I've adjusted settings and still no better. Is there a way to fix that or will that be part of the froyo update as well?

kind of wondering the same thing..

No reply from the mod so I guess I will do more research and wait till the froyo update. I may look at some other builds as well to see if there is anything better than what I'm running.

Sorry, been busy. The Froyo update I am speeking of, is some kinda of future code change directly from Google...and God knows when it will be sent downstream. Power management saying that your display is using the most power is usually correct, because well, the display is huge and uses quite a but of power. There really is nothing that you can do to make it use any less power. Android on the HD2 consumes alot of power, as do regular Android devices...and there really isn't much you can do about it.

Thanks for the reply. I wasn't mad at ya or anything. Is there a link or something to keep with the froyo updates? All I know is the site where I got this build. I am using the darkstone froyohd2v3 and really happy with it, except the battery usage of course. I'm sure there are other builds, are there any u think are better than froyo?

I'm using mdeejay revolution 1.5 and I can go about 1 - 1.5 days on a charge.
Sent from my HTC HD2 using XDA App

Wow! A day and a half on the battery. That's really good. Is that with little to no usage or are u able to use it a bit and still have decent life? Where can I go to check that out?

Radio for android

Im using mdejay gingerbread on my phone.. but my phone's battery is draining fast. Which radio is the best for HTC hd2 running android. ?
Sent from my HTC HD2 using XDA App

for my opinion, almost radio versions are same. The problem is that how did you config your phone. Just disable 3g in mobile networks, uncheck all automatic update, background apps...I used to face problem like you, but now is ok. So try to do what I did above. Good luck.

I get excellent battery in MDJ's build so it must be something what you have installed or have enabled.
There is loads of ways to improve battery life and plenty of topics about it.

Froyo lagginess - any ideas?

I haven't used the legend for a few months and loaded froyo onto it yesterday as my other phone is out of action. I was under the impression froyo was susposed to speed things up, but scrolling in the browser is still unresponsive and slow. a friend and i were trying to load up film session times - he, obviously, on an iphone - and it was embarrassing how much my webpage jumped around on a fairly graphics lite website.
I know a lot of you guys love this phone, but could I get some honest opinions: is this actually as good as it gets? Am I missing something? The phone is about as stock as it comes with the Vodafone AU froyo rom installed yesterday after a factory reset and the only apps being angry birds and astro.
Thanks,
zuka

turn on usb debugging in settings->applications->development

what does turning on USB debugging do for performance?
cheers

God knows, bu it seems to work. You could also try rooting and installing BlaY0's ROM, it's nice and quick.

USB debugging helps me ) really... It's very strange.
And i tried to send message to support (About laggs without this opt.). They ask me only one question - "What type of SD card you used" and that's all

That's really strange... because when i activate USB Debugging, my phone lag as hell ><"
Blayo Rom is really good, but idk why, since 0.6, battery draining is faster than 0.5

Sorry, I'm out at the moment and can't really search for this. Is the blayo rom stock and sense based?
Cheers for all your help guys

Being out is no excuse. BlaY0's rom is based on stock

In my case, I'm experiencing lagginess when I switch on wifi. This is a bit annoying because I use to have wifi on all the time, when I unlock the phone it tries to reconnect and the phone becomes laggy from the first 15 seconds more or less. It's only me?

No, it's normal, it also lags when "Installing..." applications.

[Q] android sd, android nand, or android ram

Any help me Ive been running mattc froyo sense desire HD for months now from the sd. Everything works with a few bugs and issues and exceptions. For starters battery life is totally unacceptable. Ill maybe get 10 hours on standby in powersave mode back light off auto sync off the works its just the android system running from the sd card draining my battery. Ill get 6 with moderate use.(pretty bad) secondly keyboard lags. HTC sense force close phone process force close. Third. Super quite voice when talking to someone else. I can turn speaker on off and it louder but annoying to do it everytime. Also led notifications don't work. AT ALL! Camera flash sucks pictures turn out over exposed. There is no torch supported or video Cam light support. I'd love to use a flashlight app on a build using the Cam light. Nother thing is ill take a picture with good quality and set as contact icon and when they call the pic quality is horrific. Also when I charge over night I only goes to 94 not 100 no matter hohow long I charge. Things that do work 3g/edge. Phone obviously. Mms SMS. Basically everything give or take a bug. Basically what I'm asking is it anyone knows from experience if there is any rom out there running from the SD, nand, or ram, that has these issues solved. Ivreally appreciate the great work and breakthroughs from all the chefs and developers. Please someone help. I wanna show my buddy m hd2 is just as good if not better than his incredible. I'd settle for any android rom with decent battey life full led notification support. Full Cam support and video support with led flash working flawlessly. Please help. Thanks everyone look forward to responses.

I'm using iamgpc band rom. As long as Bluetooth is off it will last days.

Hello gurjyotanand,
I faced the same problem a number of times. I suppose bad sectors on your SD card. If your device tries to read a file and comes to a bad sector it fails to read, but tries to read again - it goes into a loop causing high battery consumption. Formatting your SD card (not fast format) and setting up your NativeSD ROM again should solve this.
Have fun
Getrid …

Could you post a standby drain value in mA using CurrentWidget? It would help figure out whether your battery drain is high or whether it's just that your standards are high.

Alright, I have installed the widget, what to do now?
hOw to get the mA value?

put the widget on homescreen

Long press on your home screen... select widget. . select current widget.... adjust settings... you will get a small widget showing numbers... you can tap on it to toggle to voltage, battery percent and current drain
