[Q] Battery life comparison for each WM/Android combination

Hello folks,
This is my first post here so I am glad to be here. I just installed the Autoboot program for my build as specified below. I was testing the ChuckyDroidROM (which I really love for its simplicty) with both Matt's Froyo with Sense UI (which I enjoy quite a bit) and the Cyanogen Mod version with shubCRAFT 1.4 and I am finding that I am getting a much better battery life with the latter.
So basically I would like to get a reference for battery life with the tweaks here for each type of combination out there so that we can get an idea of what people are getting.
After all, I am sure that we can get longer battery life that of the EVO can we?
Thanks, Albert

as long as you put the android on sdcard, the answer is no

It doesn't matter so much if it runs on sd, because mainly it's running on memory of the phone and it's same as other android phones.
In ways it's even better/faster than phones nand if you have quick sd card.

Android need to access to sdcard to launch and work. Sdcard access has a power consumption ... So Power consumption is higher in Android, but when a Nand Version of Android will be released, it'll be proximately the same between Android and Wm.

agree with the other posts, but if your new here, read the posting guidelines. This section is for development only, not really a q&a section. If you click top left, HTC Leo: HD2 that will back you out to the main Leo section, from that point you can see the different sections and have a better idea where to post..welcome to XDA, this is one of the most knowledgeable forums I have come across.

I'm not convinced NAND will help battery life all that much, my battery use is dominated by cell standby when I'm not using the phone, and screen when I am. NAND won't reduce either of those.

I'm using TMOUS Energy Reference, Leo_Radio_2.12.50.02_2 and Xcelsior's with great results. Battery easily lasts an entire day.

I tested it out with the build in my signature and got about 12 hours of heavy use using 3G but tomorrow I plan to use only EDGE and hopefully get better life for sure.

There are too many variables in everyone's configuration to do a comparison of battery life(twitter, Exchange, POP, IMAP, Facebook, web usage, talk time, WM ROM, Android build etc). However, it might be useful to show what works for individuals and share ideas.
I don't buy into the "NAND saving battery" too much. It's still memory that needs to be accessed. It will be faster on NAND, but better battery life? I don't have the specs on power consumption per access but I would think an Android build that utilized hardware more efficiently would have bigger impact.
Take for instance your example.... why is your shubCRAFT using less battery than mattc?

battery won't improve very much in final versions, maybe -10% or so (+sleep)
but will never get as good as in WM, because android doesn't have very good optimized PM (even when they finish as much as it can be done). look at any android vs. WM device with comparable internals and you'll see that wm has much longer stand-up time
but hey if you take into consideration hd2's tiny batt i think htc has done some great job with hardware

I plan to downgrade my radio from 2.12 to 2.11 and I suspect will increase battery life a lot. Will post more later.
Testing the Xcelsior Sense build and loving it.

Uk hd2 with extended battery

A little help please. Currently running darkstone froyo with michyprimas kernal. Everything's fine but a little dated.
After a more current build with a stable kernal for extended battery. Everything i've tried either crashes or reboots due to battery.
Could somebody please point me in direction of a current build/kernal that works with extended battery.
Happy to frig about with wifi drivers etc but found searching was getting cluttered results and as it takes an hour to download, build and test each time hoped somebody would be kind enough to offer a workable solution.
If i stumble across any info will share!.
Thanks

I´m waiting for my extended battery I´ve just bought in Ebay, doing a little investigation of which kernel should work with this type of battery, found that there are at least two known kernels that support: hastarin 7.7 and michyprima r11. I´ve downloaded these three for testing:

i have the 2300 mah battery and try to find desire rom
i have the 2300 mah battery and try to find desire stock rom that works....
the only roms that work are with hastarin 7.7 does enyone know a way to make the
stock desire rom to work with 2300 mah battery ?

This works for me
hi chaps,
sorry for delay in replying. Have returned back to problem and am happy to report that MDJ_FroYo_HD_v._4.0_MDJ_S7.3HD works like a treat with extended battery.

It's usually the kernel not the build itself that support/doesn't support extended battery. You should read the change log for the kernels to see if extended battery support has been added. So before you change your builds, take a look at the changelogs for the kernels to make sure your extended battery is supported

The great battery challenge

Hello all,
I have tried a lot of the win mobile and android roms from the xda forums. But i always went back to windows mobile 6.1 as i work and need at least a days worth of battery. Having tried android and then messing with kernel changes i eventually got just over 8 hours with an average days use of texts, calls etc. I then read that in actuall fact, most of the(real) android phones did not fair much better than 8 hours anyway unless you did the recharge/off/recharge trick(desire).
So if it is possible to get the 8 hours, even if i had to muck about with complicated kernel stuff, why cant the android cabs be written with the required changes ?
In fact, why cant the devs start actually looking at their win rom/android creations and tuning them to make actually usable in the real world ?
So this is my challenge, before you release a rom try to tweak it for people who dont sit around a charger all day.
Steve.

Steve the main problem comes from the fact that android is using the micro sd all the time. With a working bootable android rom we will face also the fact that most of our hardware is now initialized by windows mobile before we launch haret and with an android rom that won't be the case.

The R/W to the microSD card is not that much of an issue for the battery life, yes it may contribute to the battery reduction but only by a small fraction, the only adverse effect of running android from your SD card will be a reduced lifespan of the memory card and possible damaging your SD card permanently depending on the type of filesystem used.
We need dedicated Blackstone developers because tbh it's all becoming a mess, there seems to be no communication or no-one testing XDAndroid releases on the blackstone before made public because if there were they would have noticed by now that they have messed up the qwerty.kl for us users, the home button which also doubles up as a task viewer/switcher has been remapped to power off since 3-4 releases ago.
Yes you can amend this in spare parts but we have still lost the task viewer/switcher functionality due to this and we now have two power buttons.
This is becoming a joke, if you put a valid point in any of these threads they become dead or ignored almost immediately.

Sometimes it is helpful to remember that this forum and many others with home-made ROMS or Android installations are for developers. User which will have stable releases have to wait for or use the offical ones. All others here are also developers or testers which help other developers. Therefore the releases here are often beta- or test-releases.
Nobody is committed to use them but everybody is invited to collaborate
And the goal is thereby a usable ROM or installation but the problem is that this is very komplex for all when it's made in spare time. And when you look what happends here with the Android installations in the last months, many issues are now solved.

Elim,
although it is obvious that using the roms/android builds is up to the user, it is also up to the user to feed back to the devs...otherwise there is not much point in making them at all, for other devs or for "beta testers" ie general readers of the xda forum.
My point in the first post is not only have htc(the actual developers) forgotten about handsets being actualy usable(read practical) but devs are now straying into the "just roll off a rom a day". No one is doubting the time and effort put into this, but someone has to man up and say it how it is. There is no point is creating roms/android if they last a few hours but can do everything(or nothing).
So again i lay down the gauntlet to devs, whether from htc or xda(or both) to concentrate on roms for people who work and there fore have no time to charge untill at home/car.

native android flash would be awsome ... dreams come true ... somewhere sometime

I dont have any problem with the battery life while running android on my blackstone, i am an IT consultant so i am calling all day long. I take it of its cord in the morning and use the phone all day until i go to sleep. so thats about 16 hours of intensive usage. I read that all people have battery issue's but my phone is running for 6 weeks without running completly dry. and i only recharge at night.
i dont use wifi or internet on it so that is maybee the difference.

Which Kernel do you use ??

If you had such a battery life, why wont you give details of the kernels etc for us to test....
So again the challenge is put down, an android version for blackstone that has battery "legs" for people who work or cant get near a charger all day.
Steve.

sorry for late response i had a 2.1 kernel, and it still works great. dont remember wich build i installed exactly but it whas somewhere from this forum

[Q] After Market Batteries suck with Android???

I've seen posts about it, but have yet to find a thread addressing it. I have been doing Forum and Google searches but have found nothing.
So what is the deal? I have an Andida battery that was great with Win Mo, but I'm convinced it causes problems in Android due to trial and error testing.
I start with a fresh build with the stock HTC battery and it rules. Then I run out of juice and switch to the after market and I lose data connection, wake up lag, and other wierdness.
I've also done fresh installs with a task29 and low level format of the sd card , using a fresh data image and if I do the same with the After Market and the Stock, the build used with the stock battery works and the same build with the After Market has problems right away.
Anyone having the same experience as me? Anyone know what the deal is?
I just purchased a spare OEM battery for 11 bucks off of ebay/USA seller. Hope it's the real deal.
***MOD PLEASE MOVE THIS TO THE HD2 ANDROID GENERAL DISCUSSION FORUM. MY BAD!***

I have found this same problem. I also have an andida battery that was awesome in winmo but sucks in android. I now use the stock battery first and the andida only when the stock dies. It used to be vice versa.

I have a andia battery and a extend battery , and both of them work fine

And this is why I need to know what's up. Doesn't seem likely to me that a battery can make a difference, but it certainly does on my phone.

is it possible that its just a faulty battery?
Or a whole bunch of faulty cheap batteries that have poorly regulated power?
I have a 2400mAh "Replacement For Touch HD 2" battery that gives my phone a hump, I got it for 12 bucks off ebay and it works great in winmo and android... my phone suffers from android sleep of death with both oem and third party batteries that I have though I think this is a mem card issue though.

[Q] extended battery rebooting

i have a hd2 which was on WM6.5, i installed the nand version of android and found it was eating up the battery a fair bit. i bought a extended original battery from ebay and found it kept on rebooting my phone straight away, the seller sent me another one and it done the same!! i tried the standard battery and all was fine, i then tried a extended battery from china that worked really good.
is there any reason why the original htc extended batteries wont work unless both are faulty?
any help would be great,,,, many thanks

Maybe you will have a look on this thread: http://forum.xda-developers.com/showthread.php?t=898818.

You just need to use a kernel which supports extended batteries.
The tytung kernels posted in the following link support it.

many thanks to you both for all your help, i thought i was something i had done or had a faulty HD2. i will go and try the modified kernells, many thanks, dave.
