Battery Life - WinMo 6.5 or 6.5.x

So I am thinking of making the switch from 21xxx to 23xxx and I read somewhere that I will see a increase in battery life by doing so while staying with the same cooks roms.
Does anyone have an opinion on this? Will the newer windows builds really help my batter life assuming the same usage throughout the day???
Thank you,
Jeff

I'm using WinMo 6.5 and as for right now my phone has been running for 3 days already with 40% battery life.

Jeff, I'm was the energy 23138 sept 23 standard rom and 2.14.50.x radio. i was getting anywhere between 24 and 36 hours on a standard size battery. I am a heavy user and when i'm at home my wifi is always on, i surf the internet a lot and if i'm out i've normally got the music player going. I also have the facebook tab updating every hour as well as my location. I also use the gps quite a bit.
So i would say the battery life is good but i can't compare it to 21916 as i have never used that series of builds and it's been a very long time since i used a stock rom, so again i can't compare.
My advise would be to try it out for a few days and see if you notice the difference but i have to say i am very pleased. I've just finished flashing and configuring 21619 sept 24 so it will be a couple of days before i can get a comparison between 23138 and 21619 (as you will have seen from the enrgy rom thread these are both 6.5.x builds) but i'm not expecting much difference considering that they use the same drivers from the 3.14 tmous base and the radio hasn't changed between the two.
A plus point though, seeing as you use the energy roms, is that xda_uc will still be able to import all your settings if you go for the same "flavour" rom i.e standard for standard or cht for cht (unless you pick the new cht2 builds then your cht settings are not compatible)

Can someone tell me how this is possible? I've had my HD2 for about 4 months now and if I don't charge it daily it's dead the next day. I'm using the new 2.14 radio and Miri HD2 WM6.5 (21916) ROM V 19.1. I have Exchange and weather on auto update and everything else is on manual update. Any pointers is a big plus. Thanks.
BTW I've tried the 23138 but I can't stand the over-sized buttons on the bottom. It's just absolutely hideous to me so I have no idea if it gets better battery life.

Extended size battery (the one that needs the different battery cover), auto disconnecting data connections, and not really using it very much at all

thanks guys for your reply, man it sure sounds like I am sucking as far as battery goes, my usage is a fraction of yours and I can barely get 20 hours. I think part of my problem is that at work, I have poor service, going in and out of coverage as I walk around the building. I have to turn off 3g and I barely have edge. I am currently trying duttys cream de la cream now 6.5.x to see if is any different. man, if I had your battery life, I would never flash again! I have latest radio, tried many, and the 3.14 rom.
I will let you know how this one goes.

I really don't believe some of you about the absolutely ridiculous battery life. Especially if you are heavy user, no way! I've seen lots of HD2's (different ROM's/Radios/battery charging methods) and I want to tell people on this board that they don't need to be worried if their battery is dead after a long working day with heavy use. So, don't believe too much fairy tales and enjoy your wonderful phone.

It does seem a little crazy huh? I hear that some Iphone users can go three days with pretty heavy use and a few that I have talked to say that thier iphone can barely last 10 hours. There seems to be a ****load of variability in current consumption amongst all variants of smart phones.
I would just be pleased to get from 5am to 11am with moderate use, without having to buy that brick battery with the built in kickstand.
I will give this current rom a week to see how the battery settles down, ignore the sig, it is the Dutty CDLC V17 with the 2.14 radio.

Why does Android on the HD2 eat up so much battery

Hi Guys,
I was wondering why Android on HD2 eat up so much battery. Earlier I was thinking, that android is running of SD card...so its the case. However this is not true as in Android HD2 NAND thread its been mentioned many times...that battery won't increase significantly even after NAND install of Android, so where lies the problem...is it because power management drivers on hd2 android not good enough...just curious?
Regards

There must be a problem with your android build or you are not properly managing your battery life. To enjoy good battery life you need to disable radios via power control, and keep screen brightness low.
Current widget tells me that in standby my hd2 uses 3-7 mA. This draw is fine when compared to similar android devices.
Please provide some details on your build and your reading from current widget.

I think he was asking about how much the HD2 life in android is shorter when compared to WM6.X
If this is the case, this has much to do IMHO about how Android works in its innards.
The Android OS has a way of controlling the apps installed in it, to know which apps do which kind of stuff. Like, when a new app is installed it has a file that tells the OS all features it does, and which of those features can be called by other programs (an example is the gallery 3d, that can be used to open pictures of certain types, every time a file that it can open is accessed android asks [if you have more than one type of gallery] which app you want to use to open the picture).
With this kind of control being done by the system in real time in a way totally different from windows (register??) the OS probably need more awake time and probably use more battery.
With the same amount of time spent using similar stuff in windows mobile and android, WM really rulez in terms of Battery Life. BUT I really prefer the new life Android is giving me in HD2. I'm really happy again, feeling like I have a brand new toy again.
P.S: I'm oversimplifying the way this works, without even mentioning the services, widget services, and several other stuff that are running in the background all the time.

i get about the same battery life in winmo n androud. make sure u have a good radio n compatible rom.

People always say those things...
Well, let me just say that I'm using one of the best combos out there, and yes I have tested almost all combos you can imagine by my self in my own phone, so I wouldn't rely on someone else's idea of a perfect combo.
Tested more than 10 roms (the list is long so, I wont bother saying all of them, but the most used ones are there, Chucky, Miri's, VBNrom, Dutty's, and several others.
About radio... 2.10, 2.11, 2.12 and now 2.14 I have used all of them too and combined them with each rom...
Right now the best combo FOR MY PHONE and in my opinion is VBN 3.14 and radio 2.14
Multi boot, autoboot android 6sec.
I really think that what is most important is the build, with the same builds, almost all WM roms made for android, and Miri, have the same effect for me, the radios I must say that 2.12 and 2.14 are the best, and 2.14 has better reception in my country, for me.
So, as I have said, FOR ME, the best combo is resumed to VBN 3.14, radio 2.14 and any android build, right now using Desire HD 3.1 from Mdeejay with several different kernells (still testing them)
The kernels and the build are the MOST important thing after you find a good combo.
With the best build/combo and a good WM rom, doing similar things (surfing the net for the same amount of time, phone in sleep mode for the same amount of time,same time talking and etc. the best battery life is surely for WM 6.X hands down.
BUT if you are really getting the same Bat life, you are a lucky guy keep the settings you have, because I must say that I have constantly near me 5 HD2 (from friends), all of them with android now, and every single guy says that the bat life is nowhere near WM 6.x
I could go a full day in WM6.5.3 and have 50-40% remaining in the end of a day with heavy usage. Android, with moderate to heavy use, I'm happy if I can reach the end of the day, and even happier with some bat left
Greetings, Santroph.

I agree battery life is not comparable to WM6.x. People who claim they get the same battery life most likely have a buggered up WM6.x setup or they don't know how to manage power/settings.

Which App are you using to monitor power consumption?
Currently I use PowerTutor.
One time I wondered how 30% of power were lost over night?!
So battery lasts maximum one day until it's empty.
On WM 6.5 it lasts for about 2 days, like santroph already said, too.
A friend of me told me, his HTC Desire has about 80% in the evening. Do they have a better battery?
In usage I have about 540-600mW
He has got 550-650mW
So seems the same power consumption.
Regards

HD2

I actually get around the same amount of battery life as well. Just running the stock Froyostone 2.1 without tweaks (don't even know how to do tweaks if my life depended on it). Current Widget shows 0mA when waken up from screen off and hovers at 3-4mA with screen on and idle. Battery drop 1-2% per hour over night.

I have TMO US HD2 and I'm using NRGZ 21916 18Sep ROM with 2.14 radio. For android I'm using pongster's HyperDroidSense V1.1. I'm using only 2 widgets HTC Analog clock and Weather channel. I have set the screen brightness on automatic and to tell u its quite dull, not at all bright. I've also disabled all Background sync's and no WiFi or bluetooth is enabled...
I do like to fiddle with my phone every now and then...but its not heavy use, I would say its moderate.
Battery life i'm getting is by the end of day, the battery is drained and have to recharge.
Before this android ROM i tried warrenb213 CM6 9/6V1.5a which is claimed by some user's to give best battery life on TMO HD2. Its stock android rom with CyanogenMod...battery life was little better, but it was slow and it didn't had instant wakeup...it took 2-3 seconds after pressing the button to wake...and personally I prefer HTC Sense UI to stock...
On WinMo my phone easily last 2 days with some battery % (about 20-30) left and can easily give me third day too with light use on 3rd day. And by no means i'm using a minimalist WinMo setup...I have CHT v1.8.5 and the same analog clock with seconds hand enabled.
So battery life on Android << that on Winmo. About the argument that Android uses more battery due to how its build. I don't think its the reason, because HTC's other phone like Desire or Desire HD have the same 1230mAh battery and have similar specs...but there battery life is similar what HD2 gives on WinMo.

Also, you must bear in mind that comparing the HD2 to the desire with battery life, the desire is obviously going to win. The desire has been made by HTC to run Android, unlike the HD2. The desire does have a slightly larger battery (i think) but the desire has been optimized by HTC so that it uses the least amount of battery possible I.e when in standby etc.
I don't know all the specifics but this is what I've found out
Hope this helps

^^ya, i do understand...but to me its happening like battery life on hd2 w/ android is like 15 hours from 7am in morning to 10pm in night....WinMo give easily gives like 50-60hours depending on use...desire has similar as i've heard...
Agreed not optimized, but I expect it to give 40hours with full charge?

It is not optimized I guess? I get 6-7 hrs on winmo but 5-6 on android.

We can't compare with Desire, even if the hardware are really similar when looking at CPU/GPU, RAM, radio and stuff like that, we have e HUGE NORMAL LCD screen, that really takes way much more battery than Desire's Smaller Amoled screen.
Recent tests have shown that the new desire with Super LCD (thats way better than ours) do waste more energy than the AMOLED one (despite what HTC has to say about it).
I think that we should compare it with our own phones with WM, and probably with the new Desire HD or Evo 4, which have the same Case/Screen and very similar hardware too (despite Evo beeing CDMA).
IMHO...
P.S: People say that the SD card doesn't have anything to do with the battery drain, and that nand should be the same. Well I can say that this IS and IS NOT true... It all depends on which card are you using. I have 4 MicroSD cards, and they all have different behavior with the same combo/build/kernel/battery, even when in sleep mode with everything else (connections and all) disabled.
I have used WatchDog to see if any program was strangely making this happen, and I didn't find anything at all different when the Hungry SDcard was using that much battery, it was all it's fault.
2GB class 4 -> 5-7ma stable
16gb class 2 -> 3-7ma stable
8gb class 2 -> 5-9ma stable
8gb class 6 -> 5-80ma not stable (can be ina 5-7ma for hours and suddenly be in more than one hour in 40-80ma)
I prefer to use the 16gb class 2 for more battery, since the performance is not that better with the class 6 in android.
I've tested this a lot, and retested.
Greetings, Santroph.

I think that the HD2 battery is shortened by the display (Samsung Vibrant is awesomer in that respect) as well as the processor. If I throttle the processor down to 384mhz and keep the screen at 33% (automatic backlit) then I can get pretty decent battery life from 15-24 hours?

[Q] Battery Drainage

Been trying alot of builds recently trying to get reliable gps (+ compass) and decent battery life. I really like MDJ's desire HD build nice gps + nav and best of all loving the new sense interface. But as with a few other builds i have tried recently battery drainage has gone through the roof.
To compare to darkstones desire hd build i get 3-8 mA in standby and i can get around 18-22 hours out of the phone. But most of the recent builds i am only managing 8-10 hours max.
I have tried shubcraft 2.0, the latest hyperdroid, the latest MDJ evo and of course MDJ's latest desire hd. All of which have increased significantly in battery drainage. But when i switch back to an older build battery drainage falls in line again.
Is there something i can do to sort it out? As i see a lot of people report decent battery life whereas my observations are totally the opposite.

looked but can only find everything ive been doing ever since android was first developed for hd2. using winmo battery tweaks, setcpu, turning off all unnecessary wireless (wifi, data, syncs) using a android loader + making sure keypad lights are on. only thing new i found was your post about reconditioning the battery to let it know when it is actually full. none of that addresses the 100+ mA i get in standby and neither does reconditioning the battery.

Batter Life!!!!!!!!!!

Okay I am now running an Energy Rom, still every build that I have tried, the battery drains so fast!! It is almost unbelievable. I can not get a days worth out of this thing, I have turned off background data, and everything, and it still the battery drains like crazy! What is the point in having Android on this nice phone, when the batter drains too fast, you can barely use the phone? I have tried builds that include Kernel 8.5.1, still battery drains.

Download current widget to see your mA, I thinks that is battery voltage...what radio are you using and WM rom?
With chucky lite, radio 2.12 and froyohd2, if I don't play angry birds my battery still last about all day... And around 7mA in stand by.

I like the Energy Rom, can you give me a link to the FroyoHD2? Also I heard there was a Froyo with no sense ui, but I can not find it. My Radio is working just fine, I have 2.12.50

The answer to this question is all over these forums. 90% chances are the issues are between the 4.2" Screen and You.
With the right settings/configurations, you can get pretty damn good batt life.

4.3"..... Sorry its nexushd2, its froyo no sense. It's in this hd2 android dev threads

my hd2 cant live without car charger......

i've bought a hd2 yesterday. And I will use Android on it. Can anybody tell me the time of the battery life, if i use my phone for gaming etc. and if i don't use my phone often? Is 24h a realistic time?

Try the MIUI build (any). If you like the nexus one builds you will definitely love the MIUI build. If you don't like the iphone looking style just install ADW or launcher pro from the market. You will also need to use an android friendly wm rom. Use vbn with excellers multiple build loader both are found in the android development section. When you use the build loader app chose auto boot 3 seconds, ( you will know what I'm talking about when you are in the app). Hope this helps

i tryed just about every rom, got atleast 24hrs with all of them. most were 48+ with conditioning... for me bat life was more an isue of shutdown voltage in the kernel than any thing else..

Strange some people say to switch to that from Desire or Desire HD builds because it has better battery life ?
I am running
MDJ Revolution 1.7 with MDJ 7.6HD Kernel
Radio 2.15.50.14
I find that the above radio is better on battery than my previous 2.12.50.xx
Also the Kernel is better too.
But it depends on how much you play with your phone I get 3 - 7ma drain on my current setup but of course when you start calling or playing games it will easily go up to 200ma.
I find the above rom very stable I can't find anything that doesn't work and its fast enough for me I don't notice any lag or freezing.
I was thinking of switching to your ROM to try but if the battery life is that bad then I may stick with this.

guyz lil but of an update here still on the same rom and i've manged to last 14 hours and i still have 72 % in the battery, with very little usage a couple of texts couple minutes of browsing and some music
im using setcpu greenpower and advanced task killer
ssetcpu is at the minimum
advanced task killer set to auto kill - crazy (means it kills apps as soon as screen goes off)
greenpower set to manage wifi and mobile data, turns off wifi and data when there is low traffic and turns it off as soo ans the screen goes off
its working for me so far so just wanted to post it up incase anybody else wanted to know
