Android build and rom for long battery life

hello
im have HD2 512 MB rom with ChukyRoM and rEVOlution build in it.
my battery life is horrible.
after 5 minutes of music without screen i got 2 percent drain from my battery.
i can barely complete a day without battery runs out before 3PM
can anyone recommend me the best sense build and rom for battery life?
i desperate
sorry for my bad english.
can anyone help?

Hello, use my settings + low screen britness
T-Mobile HTC HD2
Cotulla HardSPL
OMEGA ROM
Mdeejay eVo Sense v.2.0 REVOlution
Stock Radio
this last for 1 day with normal use

omega is good for battery life?

what sd card are you using? i might be wrong but most of the time, battery drain is down to the type of an sd card you are using rather than what winmo rom you have got.

sandisk 2GB MicroSD is that really matters?
what about radios,that can help too,right?

if the configuration of android settings (like backlight, autosync, set cpu) does not help to reduce battery drain, then try a different radio and sd card as well. unfortunately, i cannot tell which radio and sd card to use, since it is rather subjective. i personally use Samsung 8 gb class 6 sd card, running FroyoStone 3.1 on the latest stock rom 3.14 and radio 2.15.50.
also what is your batter drain in mA during standby? you can check that with Current Widget from the marketplace

il try another radio.
in standby i have 30-60 ma
on music or games i have 200-400 ma
that terrible

30-60 mA in stanby is a bit too much, average should be around 7-9 mA, but there are some that can get even less like 3-5 mA. 400 mA while playing games i think is alright.

Well, this works for me...

I switched rom and did your guide.
still didnt help.
any other ideas?

any other ideas? please!

Are you using setCPU?
edit: just noticed you said you had followed that guide which is all about tuning your CPU, so you can disregard the above question.

Try to use different windows rom
As I know ozdroid, Chuckydroid. And vbnrom are the best.
Or try different radio 2.10.50, 2.12.50 or the latest 2.15.50
Or sometimes try to restart the device will work

Make sure your running apps aren't sucking power behind the scenes. I'd try by killing off suspect apps one or two at a time. Even if they pop back up (because of a widget or other background service) it can help because it kills a service that they are running. don't use Auto Kill though or it might increase your battery use.
Have you cleaned any widgets off your homescreen that might frequently use CPU?

any other ideas?

[Q] battery drain with ram builds

hi, i've just discovered darkstones super ram build, which will be loaded from sd to ram at start. i read about 12 sites of his thread, but no one was asking after battery drain on that build. well, here's my question:
will be battery drain less then on builds operating from sd card? please post some experience with that build
thx in advance!

let me present you my results
revolution 1.2 on SDcard = 7mA in standby
RAM darkstone edition = 6 mA in standby
But it depens on other stuff too. Seems like battery consumption is same and still depens on kernel. RAM version gives you the speed but consumption is same.
Theese are my results. Others may have different experience.

thx for sharing. i imagined that ram builds don't spare much more battery than normal builds. i will keep on mdj's froyo hd build then...

Thanx
How much HD2 consumpt in "not-standby" state in RAM edition?

frankly, i find that my battery drains faster both in standby and non-standby with darkstone's superRAM than JDMS defrost build. i did not check whether it's a kernel issue but no improvement in terms of battery life here.

Android?

Hell all!
i considering to go over to android on my HD2.
Have try some SD version, but always go back to WM 6.5...
Are there some NAND version for daily use, with no problem and less powerdrain?
The speed are not so important, but i´m not happy to charge the battery every day.....
Tnx for Your answer.

Yes, most of the current NAND builds (ie the later ones) are very stable and if set up right can draw even less power than wm.
The one I'm using is linked in my signature if you want to give it a try.

Hi,
I am using Android on nand since MAGLDR has been released. What can I say is works better at this stage of development better than WinMo ever, at least for me. The rom I use (link in my signature) is super fast and stable, no problems so far. Also the battery drain in my case is lower than on WinMo. With 3G, GPS, background data, weather sync every 30min, facebook sync every 30min, emails sync every hour I get 5-6mA on standby which is very low. Battery drain depends also how you are using your phone, if its a lot of gaming and browsing over 3G it will drain faster. I charge almost every day, cause I play a lot on my HD2 There are so many different types of roms, you have to choose from. I need to mention about some minor bugs as well, but they are not big issue. Usually dev or chef writes about bugs in his rom in firsts posts of his thread. As always decision belongs to you.

Using "MDJs_CyanogenMod7_v.2.6_NAND_A2SD+" ROM. Music, internet, Jabber, calls, camera. CPU is overclocked 245-1420 MHz by SetCPU. Have no problems with excessive battery drain. What I'm doing wrong?

There's really not much difference in performance between nand builds and sd builds. Battery drain is the same... I get 3-5ma power drain on standby with most recent sd builds. Main bonus with nand builds is you can use clockwork recovery and you can switch sd cards while running android. If you are not going to use winmo anymore, you might as well put android on nand... but if you still want to use winmo, there's not that much gain by running android from nand. I prefer having 2 OS's on my phone that to have just one. I used nand android for a month or so, but I'm back to using sd card builds because I put wp7 on nand... and performance and battery life are just as good with sd builds as they were with nand builds. With either nand or sd builds, if you put your settings right, you can get decent battery life... it's just as good as winmo (maybe better if set up right) if you casually use your phone and leave it on standby most of the time, but with intensive use, android, both sd and nand, on the hd2 eats batteries quicker than winmo did.

Try the jaws-miui, it's awesome.

Android Nand or SD boot. Which is better?

I haven't tried any nand android yet, but i'm start thinking of using full android w/out winmo. The reason for that its just that the performance of my android sd build is getting slower in these few days. Laggy sometimes. Not just that, even my battery is kinda drain quite fast too.. the average battery usage now is like 9ma - 20ma on idle. It used to be like 1 - 4 ma on idle.. I don't know exactly why. 3rd party software problem or maybe i got too many of software/games which leads to a high transfer rate on SD which affect the OS operation (laggy) and drains the battery.
So from your experience:
1. Which is better nand or sd? why?
2. What is the advantage and disadvantage using nand and sd boot?
3. Any difference between nand n sd build in terms of performance?
4. What would you suggest for me in order to remove the lag and high battery consumption on my android sd build?

1/ can't say cause if you have 1-4mA at idle it's good.
2/ no WinMo (advantage if you don't want it, faster boot time, no risk to receive calls or SMS in WinMo.. disadvantage if you want to go to WinMo sometime)
3/ I imagine NAND is better for battery consumption... but your 1mA at idle show me the opposite.
2/ don't understand your question...
Don't understand your SD comment. 16Gb is good, class4... hum never feel a noticable difference between classes... but all is in NAND for me.

thanks for the suggestion and answering the question.. i edited something on the thread to make it more understandable.

Ok, I never made some "serious" measurement regarding anything, so my advices will be based only on my feeling.
I tried Android on SD until I convince myself that I prefered Android.
So I choose the NAND to:
- boot faster (I gain the WM boot time)
- reduce my battery consumption (I put all in NAND to reduce the SD access)
- have the ability to remove the SD with OS booted
- performance difference... I really don't know. I don't know the memory techno of the two. RAM is faster... but NAND and SD, for me the techno are close so...
What i'm close to be sure is that even if you don't put an OS in NAND it will be always powered by the phone. So waste of energy. If the OS is not stupid, I hope it has the ability to cut the power of the SD when not in use. If it's the case... less consumption. If not, the dev is stupid... and my consumption will be the same.
My feeling is that the battery life is now very close to what I had with WM.
My advice... test a NAND.
Don't judge the battery life before few days. the first days it's not very good, you can feel it only after few days (looks like auto calibration of the system...).

Second advice. If you don't want a Sense build, test this one:
HyperDroidGBXv4.0
I don't say it's the best. Comparison between build/dev are stupid as a build match a "need". The best build for me may not be the best for you.
So I like this one, that's all.

yeah same goes for sd boot. The battery life is kinda great in 1st month.. but idk why it started to lack in these few days.. the phone should be like 2 days or 3 on my average usage.. but now it only survive in just 1 day.. thats why i was thinking about moving fully on android since i used it daily..

yeah well thanks.. rom is not the issue.. its okay with any rom.. i actually just wanted to know the difference in terms of performance and battery life between nand n sd.. u really get my point.. so there is.. guess i'll go for nand then.. thanks.. really appreciate it..

You missunderstood what I said regarding battery life with NAND. Just after flashing you will be disappointed. The battery will not be good.
After few days only you will have the real one.
I never encounter what you describe with SD build. I think I never keep one long enough (I was a flash addict).

[Q] NAND vs SD. MAGLDR vs CLK

Hi there,
I have been running SD Android builds for a couple of months, still a beginner. I'm happy with WinMo + Android SD build(s) ... however would we made any progress if we don't investigate further ...
Would NAND Android be any better than SD builds, specifically on Battery & speedness?
Would you recomend NAND vs SD?
MAGLDR OR CLK? What are the differences?
If I want to go back to WinMo ... would it be as easy as having the original stock rom (.nbh file) in a blank microSD and enter the boot loader?
If you still have energy after so many questions, one not as important (I can test myself) ... any ROM recommendation?
Many thanks to all those that make XDA-developers be XDA-developers
Pozi.

hey pozi,
I would recommend using NAND, it's a great experience. a TON better than winmo 6.5. I have great battery life, and the speed is as if the HD2 is an android device natively.
MAG vs cLK: I've tried both. The differences are:
cLK boots faster, and doesn't have a cmd prompt screen during boot.
cLK uses PPP for your data connection (MAGLDR uses rmnet). Sometimes you'll have a data drop that can only be fixed by rebooting your phone with PPP. rmnet is completely stable.
For NAND, to get back to winmo, you'll have to flash the official winmo6.5 ROM just as if you'd flash cLK or MAGLDR.
As for ROMs, it's totally up to your preferences. I've used a few, and currently I'm using TyphooN 3.6.0 because it has all the customization that I want. There are other kinds, you'll just need to test with a bunch to find what you like.

Thanks for your answer.
What does great battery life mean for you: 12h, 24h, 36h, 48h ... ?
In average, I'm just trying to have an idea compared to my 12h on SD.
THANKS AGAIN.
Pozi.

It depends on your setup:
What accounts are syncing, What apps are using background data,... you probably know the drill.
I use an app that disables my data usage and periodically re-enables it to sync with everything. So far my battery hasn't lasted any less than 13 hours.

Hi,
im used to flash the Boyppc's roms with cwr so on Nand after have handled a lot of builds on SD card. The battery life is great (2h of music, mail and internet 2-3h and others things with from a mobile so i use 60-70%) the speed is awesome and no problems if I need to remove the card from my phone.

I have tried many roms, I change every few months ... Until I find the "perfect" ROM...
I recommend NAND.
In my opinion it's faster, more stable and less problems.
Great battery life. With normal use you can enjoy almost a day of battery.(but if you use 3G the battery dies)
Right now I'm using the rom TyphooN_CM7_v3.6.0 MAGLDR, my favorite.

===========================================

Yes definitely go for nand. Its so much smoother and faster than an SD build. I would imagine that android nand would conserve battery life vs. SD just because nand isn't going through so many processes to make your phone run.

Heck, if you really want to save your battery turn on airplane mode. You'll go for days

I would also agree with the other posters that going with a NAND ROM gives you better battery life than an SD ROM. For me, my current NAND ROM has a standby battery drain of 2-5mA vs. my previous SD ROM with a standby battery drain of 7-9mA. I am currently using Tytung's Nexus HD2 v3.0 ROM. Very stable and fast. Everything is working very well. No force closes or drops in data. Market is very stable as well. Call quality is very clear and probably is one of the best that I have tried. I use MAGLDR since it is very easy to use, is very stable and compared to an SD ROM, is much faster to load from off. Try 45-50 seconds from off. If I remember, my SD ROM took almost 4-5 minutes to boot up from off.

As i have just readed the posts would say that your main problem is the BATTERY thing..right??
NAND is is the most stable , fast , battery saver , that you can offer to your phone..as all the people of xda writing above me ^^.
Now if you care about battery try finding a rom thats STABLE ...and not fancy with Effects and cool weather ,live wallpapers and many many other..try getting something stable - fast - and with no much bg programs to run....!

Thank you all.
I've gone to a NAND MAGLDR ROM and I'm VEEERY HAPPY ... at least now .
Already looking to the change rom process so that I can find the one that best suits me.
Thanks again,
Pozi.

Dayly use, so:
phone + bt + wifi + good responsiveness/overall speed (actually Speed IS important)
gps (not frequent but must work)
battery life (*)
HTC Sense or SPB Shell ready ... any other fancy launcher?
Good to have: navigate through PC's internet connection when USB connected (though saving battery due to not use WIFI and not use my little 3G data plan). Maybe this can be added with an .apk ?
Thanks Pozi.
(*) By the way Panda_Face I followed your suggestion of flight mode to save battery, it did work and saved a lot of battery

There is a "patch" of sorts for GPS which makes it connect a lot faster. It usually takes a few minutes to get any sort of lock from the satellites without it. (Click here to read about it).
I'd recommend either the TyphooN Cyanogenmod or the Nexus HD2. They are both very stable, and have all the latest and greatest stuff for them. They are also well known. Their forum pages have been viewed millions (not joking) of times, so there is a lot of support. And as far as I know they both have everything working (phone + bt + wifi) are very responsive.
To help with responsiveness use just a plain old normal wallpaper. The live ones --from what I've seen--- tend to lag the scrolling and flipping home screens and such.
I use an app called "JuiceDefender". The free version turns off my data connection (3g) and periodically turns it back on to sync with email, etc. The other paid versions of this have more options such as managing your wifi and other connections. This alone has doubled my battery life.
Hope this helps!

Currently on TyphooN Cyanogenmod ... will keep an eye on the Nexus.
Thanks.
Pozi.

i use a patriot class 10 SD card running AmeriCan Android, and it is uber fast.... has anyone ever compared the speed of a class 10 and NAND??? im really curious about this to decide if i want to use NAND or not... lol, i just dont know if it is worth it to redo everything for a little extra battery life... lols...

Battery life is a plus. NAND is nice because it makes your phone feel now like a native android phone. Also you get to dedicate more space on your card for things. finally, you'll be getting rid of winmo 6.5 (worst operating system ever) it killed my first hd2; wouldn't boot one day.
Android NAND is the way to go
Sent from my HTC HD2 using XDA App

I would also agree with Panda_Face, Android NAND is the way to go. Very smooth and fast. Much less memory intensive. Gingerbread ROM that I am on used a zip file of slightly less than 90mB vs. my old HTC Sense ROM using 445mB of space. Both NAND ROMs were smooth and fast but going with the "lighter" Gingerbread ROM gave me a much faster boot up time. Less than half the time the HTC Sense ROM I used. Battery life is better on NAND vs. SD. Also, when I was using Android via SD, I never realized until I went NAND, how the SD ROM was not smooth when compared to the NAND ROM I am using now.
