Yeah, I've done all the tips and tricks and charge with power on the power off and charge, wash, rinse, repeat. Nothing works. I'm curious to see if the "free" battery they gave me will last longer.
[EVO 4G General] mjz147:
I was in the same boat as you.

I have a fix and it should work.

turn on always on mobile data and enable auto sync

I posted a thread about getting rediculous battery and someone told me to do that and it worked.

go to settings all the way to the bottom to about phone Ans then choose battery. I bet ur up time and away time are the same. if they are that means something is keeping your phone on even tho the screen is off. doing what I told you above with a restart should fix the problem. also when you restart it its not going to instantly go to sleep leave your phone for like an hour and then check the up and awake time and it should be different. hope that helps.
[EVO 4G General] mjz147:
and enable data when roaming.
[EVO 4G General] MCL1981:
Without specifics about what you have the phone doing and what kind of signal you have at home/work/etc, this is a totally irrelevant discussion. In my experience, the only thing that actually kills the battery quickly on the Evo or any other phone is poor cell signal.
[EVO 4G General] Vdek:
I get well over a day on my evo... Running the netarchy kernel along with setcpu profiles. I have my phone set to clock to a max of about 384mhz when the phone screen is off.

I did the battery recharge trick and it helped a lot. I also have my display timeout set to 30 seconds.

Dump the Mail app and use Gmail to pop your accounts

If you are using the MAIL app that comes with the OS, that is likely the culprit. Especially if you are syncing more that one account. That can kill the battery very fast.

**try using the gmail app, and set it up so that it pops your pop mail accounts for you and pushes them to your phone. Then disable the built-in mail app and never use it again. This alone should double your battery life. It worked on the Hero and it works in the Evo.**
[EVO 4G General] tsunami0ne:
Do you by any chance use Yelp? I did an experiment last week with Yelp. Without the Yelp service running in the background, I would lose less than 8% of my battery overnight. With the Yelp service in the background, I lost about 50%. I've emailed Yelp to see if they can disable the Yelp service if I don't login to my Yelp account through the app.
[EVO 4G General] jigglywiggly:
Putting my phone on wifi made it so in the morning (4 hrs of low signal then to 50% battery), I put ti on the school's wifi and it was 80%.
[EVO 4G General] mayurolla:
I would avoid doing this. Lithium-Ion Batteries (found in the Evo and almost all other phones and laptops) can only go through a certain number of charge cycles. This method will not help prolong battery life.
[EVO 4G General] EVOKeith:
So I put the "free" battery in and turned off background data. I have been unplugged from the charger for 6 hours, and my battery is at 63%. That is with email being checked every 10 minutes through the default email application, some gaming, Facebook, light texting, and a few phone calls. This is a HUGE improvement from before. I think I'm going to go ahead and root my phone and see what all I can get out of it.

Thanks for all the replies.

There is no way that you are getting 1.2MB/s download speeds with 3G. I think that's even beyond the theoretical maximums.

May sound stupid, but make sure you are running the latest patch, or their is a facebook sync bug that can cause constant data usage, drains the battery. Only way to fix it temporarily is to remove your account and readd it, there seems to be a facebook server side bug right now that is causing friends to not resync, wonderful.
[EVO 4G General] MCL1981:
And here still we have no idea what you signal strength is like. The biggest killer of batteries is poor signal causing higher radio power draw.
[EVO 4G General] wase4711:
or, a defective/bad battery...most likely the culprit here, since the replacement battery works fine..
[EVO 4G General] EVOKeith:
Very sorry. I live in the greater Dallas, TX area, so I have very good signal strength all the time. I don't use 4G at all unless I am closer to downtown and feel like running a speed test.
[EVO 4G General] EVOKeith:
They "tested" my old battery and said it was perfectly fine. I'm not sure what test they ran, but it took all of a minute and half to do it. The way it came across is "damn, it's another bad battery, let's give him a free extra and see if it makes him go away".
[EVO 4G General] topdnbass:
Root isnt necessary for good battery life.

I am at 22 hours right now with 45% battery life remaining.

Stock, no special tweaks..

Just watch what you install and make sure your phone is sleeping when the screen is off.
[EVO 4G General] sablesurfer:
Yeah...moderate usage here...short'ish calls (<20minutes), texting, camera, occasional game time, lots of internet, occasional podcast...I easily get 12-15 hours of awake time out of mine. No root here yet.

I did set my syncs to 4 hours and I do not have live wallpapers or any RSS/News/Facebook feeds.

On the new OTA though I find that Google Talk is CONSTANTLY restarting itself. On the old version I'd kill it once a day and it would only show up if I went to Market. That ticks me off and I kill it now about 5-6 times a day..(well just force close from Manage Applications)

Oh...and I have the battery widget running all the time and just recently put YouMail widget on to see how it would work. Still making it from home back to home some 11 hours later and only plug in around 10pm before bed.
[EVO 4G General] sablesurfer:
Forgot...I do follow that HTC recommended charge process about once a week though. That power it off, charge to green, power on, charge to green, power off charge to green.

As for the poster that said only so many cycles...these are not cycles...these are topping off as the phone charges different when on vs off. HTC released the recommendations.

How many users of laptops take the laptop to a meeting...then back to desk and plug in? They do not run it all the way down before replugging back in....and while it is in the dock it is trickle charging the whole time.
[EVO 4G General] the_hustleman:
5-7 hours is about right w/o rooting is quite generous with regular usage.

now if you're only going to do light usage (nothing major, just a little here and there) you'll get a lot more.

heavy usage will get you a MAX of 4 hours lol.

but I rooted my phone, added overclock widget, and I get about 8-10 hours of use with regular usage, or if I use it a lot, I'll only get 5-6 hours.

if I leave it alone however I'll get 2 days with only sending a few texts and a couple calls.

but you're not gonna get great battery life out of hte phone if you're USING IT!

Beleive it or not your problems are being caused by your Micro sd card the same thing happened to my brother. It is very easy to verify just remove the card and watch the difference. You will have to format the card using the slow method. Your battery life will more than double.

[EVO 4G General] the_hustleman:
How is this misinformation when I've tried an proven it?

I'll post screen shots later, but if u look at it, the screenshots showing exceptional battery life have very high idle and standby times. That means the phone is just sitting and not being used. I didn't pay 200 bucks to have my phone sitting, I use it. And that is what kills the battery. If I can get 24 hours of actual usage I'd be thrilled

[EVO 4G General] notasimpleway:
Where is the nightly build posted? I lost all my links.
[EVO 4G General] Zabalba:
This will not harm the battery. Also what that method does it reset the max capacity that the phone will recognize as "full".

For example before applying the method the phone will say "Hey your battery is fully charged" when its really 80% full. Turning it off and forcing to keep adding charge calibrates the internal battery monitor.
[EVO 4G General] baiatul:
I heard about this in Egadget or one of these blogs. They said EVO's circuitry doesn't know when the battery is really full. It just kind of guesses. So it stops charging when the battery is still half empty. A firmware upgrade was supposed to fix it, but the difference is not that big. Also someone here said that the battery lasts longer when it is charged on an external charger, not on the phone. So that would confirm that EVO is not good at charging. These steps also seem to confirm it.
[EVO 4G General] DarkManX4lf:
Do you have to do this every time you charge your phone? Or is it a one time thing?

Is there a way to keep YouTube videos (or any other videos for that matter) playing in high quality, rather than having to click the left key -> More -> Watch in high quality every single time?

Cheers
[XPERIA X10 General] dpk0875:
you can find several apps that can download YouTube videos in the market

in the market type YouTube downloader and apps should appear

I tried a few and liked jetvd the best, however I use freedi YouTube downloader - its been discontinued but you can still download from the developers site an old version and install it.

I also saw that there's an app called freedi YouTube download helper but you need to have dolphin browser or login with YouTube account so I didn't bother with it

hope u got wat ur looking for
[XPERIA X10 General] chris_knows:
Just use Skyfire and go on the full YouTube site, it should automatically play them in HQ.
[HD2 Android SD Development] mskip:
Without the inclusion of proper documentation included with an Android Rom or an Android Build users will start filling up the HD2 Android Development Forum with why this wont work when it does on someone elses Rom. To stop this from happening there will be a requirement when creating a Thread for a Rom with Android included, or an Android Build.

------------------------------------------

------------------------------------------

If you are making a Rom with Android built in or an Android Build that is run from haret then please INCLUDE with your file a readme.txt file in the ROOT of your release archive with the following information:

*What BUILD version?

An internal version # that can be used to identify the authors exact release (e.g. my-rom-v0.5.zip) for easier reference for the users and fellow developers benefiting from the release.

*Which kernel image and kernel modules are used?

Where are zImage and modules.ko originally downloaded (in case the chef didn't compile on their own) and where is the kernel source code for the kernel and modules.

In case the chef did not compile on his own, he should still be able find out where the source code is.

(The license under which the Linux kernel is released requires the distribution of the source code that was used when distributing builds.)

*What rootfilesystems are used?

Where was it taken from, what does it include (android version it's based on etc) and in case of self compilation, where is the source code.

(In case of most windows mobile shipped devices that's often some rootfs file e.g. named android.ext2 and an initial ram filesystem often named initrd.cpio.gz).

*ChangeLog*

A ChangeLog is really an essential addition in every build as it informs the end user what modifications have been made from the last build. This will save you ALOT of questions as to what has been added, deleted or modified and therefore is a requirement for everyones benefit.

*WindowsMobile version your Android Build was tested on*

Please include your WinMo Build version, HTC OemDrivers (if known), XIP (if known) and Radio version so that users know what the Android Build was tested on and can replicate if neccessary for fault finding purposes.

------------------------------------------

------------------------------------------

If you are unable to obtain any of this information and thus can't make it available through an included readme.txt you should not distribute your rom and keep it for personal use only.

If you are using an exact copy of a present release (e.g. in case of a WinCE rom that has an android 'dual boot' option) you must include the readme.txt from the original rom chef.

If you release a Rom and do not have the required information then you will be asked to either create and include a readme.txt file with your Rom or ask for the thread to be deleted.

If you have any comments or questions on this please feel free to post.

Mark.

[HD2 Android SD Development] dcordes:
Thanks a lot for the quick action, Mark. I am glad to see a first positive response.

If this will establish I hope that

*users are informed about what they get

=>less unneeded questions and thus more room for constructive feedback

*developers have an easier time to benefit from present releases

*new developers must try to get an understanding of what they are doing

=>more quality releases

The original post can be found here.

I think it would be nice to hammer out the readme.txt requirements together with chefs so we can get some convention that satisfies everybody.

edit: Think it will really be good to always put readme.txt in root of release archive so everybody knows where to look for it.

[HD2 Android SD Development] ahbad:
May I suggest that the readme include the date of ROM compilation, as well as the date the kernel and root file systems files. I think this will help users and chefs to easily build there own compilations and keep track of it's validity.
[HD2 Android SD Development] shufflez:
And a title format like: [date]-[name]-[version]-{[kernel]-[kerneldate]}-{[modules]-[modules-date]}-[rootfs] (just like rules for 'regular' roms). Both for the post and the archive preferably?

Personally I switch between versions a lot, to find differences/improvements/bugs.

Clear archive-naming should simplyfy this :).
[HD2 Android SD Development] dan1j3l:
Excellent rules! We need to improve stability of ports and eliminate all unnecessary questions !

P.S. Hope there won't be any "bogus", or "copy-paste-claim" ROM-s.

dcordes an mskip +1 :)
[HD2 Android SD Development] dcordes:
Very good idea. I think we should at least add the rom release date to minimum required readme.txt information.

For the rootfs release date I think we should leave it up to the chefs because I think it will be hard to find out in many cases. Reason is rootfilesystems get passed on 20 times...

In case of the kernel release date it might be a good idea to add it. should be easy to find out. When you grab the kernel e.g. from the two sources I link to in the thread

http://oe.netripper.com/files/htcleo_autobuild/

http://cotulla.pp.ru/leo/Android/

you can just copy paste the date from filename or information on the site. This would be very useful assuming the kernel images will be removed at some point.

On a side note: For both kernel examples the source code repository to add in readme.txt is

git://git.linuxtogo.org/home/groups/mobile-linux/kernel.git htc-msm-2.6.32

gitweb: http://git.linuxtogo.org/?p=groups/mobile-linux/kernel.git;a=shortlog;h=refs/heads/htc-msm-2.6.32

So currently in every leo rom readme.txt this must be linked to as kernel source reference. netripper autobuild zImages using this exact source code and cotulla zImages share same codebase (although currently the latest changes are unavailable but will be added in git soon)

To me that seems over exaggerated. Rom version in file name should be enough. Rest can be looked up in readme.txt

So what does everybody think? If we add the release date of kernel and completed rom, do we have an agreement ? In that case we should compile an example and add it in the first post.

best regards
[HD2 Android SD Development] David Balfour:
your right dcordes too much information in the title can be a bad thing. Something more like

[Date] [Name] [Version] [Build] [maybe Kernel version]

That should be Enough i think so for Example

[21/07] [Darkstone1337] [v5] [Eclair w/sense] [2.6.32]

Everything else should stay a change log for people to read
[HD2 Android SD Development] dcordes:
I am sticking with my opinion:

*in filename require internal chef rom version

*in readme.txt add:

-rom release date

-kernel release date

Mark what do you think? Any other opinions?
[HD2 Android SD Development] ivku:
Install to folder

May be a good idea install all files to appropriate folder, not directly root of SDcard as in last darkstone FROYO. Greatly simplify process of testing and changes between several images and don't messy root. Switching between different versions is than as easy as renaming directory.
[HD2 Android SD Development] dcordes:
I think we should also leave directory structure etc to the chef as long as readme.txt with all the required information exists in archive root so users can find it easily.

so do we have some agreement here? Mark ? If so you should update the first post to compile final set of information needed and clarify that it is not a nice extra but a requirement.
[HD2 Android SD Development] mskip:
I agree with you on this theres no need to make things more complicated than they need to be. Although there does need to be some sort of standard for the thread title.

And no I cant think of anything else right now that needs to go in.

Also agree that its upto the chef how they want their files set up as long as its clearly stated in the readme.txt what to do to get it working.

Everything sounds fine :) What needs adding to the first post to make it complete?

Sorry I have been working on my Loader but its all finished now (I hope).

HD2 Android Image & Instructions

Hi All,

Can somebody confirm if there is a working Android image for the HD2 yet? From reading previous threads, it would seem there is still some technical challenges, no image is available yet.

If I am wrong, please could somebody tell me the location of an image and instructions so I can install Android on my HD2? I am struggling with WM6.5 and I much prefer Android. I have used WM for 9-years now but it just doesn't compare - partially because there are limited decent apps available.

All the best,

Youdaler
[HD2 Android SD Development] mskip:
I will just give you a friendly warning this time as it is your first post. This thread is for the discussion of information to be included by Android builders.

If you look in the Android forum then you will see working builds by DarkStone and by Dan1j3l. Look at their threads for how to load Android. to answer your question yes Android does work (95%) on the HD2.

Please confirm you have read this so I can delete these posts and keep the thread clean. In futured please only post in the correct thread and if you arent sure then post in the Q&A thread at the top of the Android forum.

Mark.
[HD2 Android SD Development] youdaler:
Understand. Thanks for clarifying.
[HD2 Android SD Development] dcordes:
I think we should extend the readme.txt items with some section like 'expected issues' or 'known problems' .
[HD2 Android SD Development] Miyagi:
And in the readme.txt , could help too:

Tested with:

-WinMo rom x.xx.xx

-Radio rom 2.xx.xx
[HD2 Android SD Development] mskip:
A readme file doesnt really need any more information then how the build was put together, what is included and what does and doesnt work (to date).The whole reason for it is so people know what they are loading and have the right information to report problems or get help. Over complicating it will just lead to people not reading it, things like the system it was tested on are best left in the first post of the discussion thread and may cause more confusion.

I do think that a link to the builds discussion thread should be included so that people who have had it sent to them or just given the download link have access to help if required. If there isnt a discussion thread then a link to the HD2 Android Development Forum should suffice.

Is there any more input on this or can we come to a conclusion on this.
