I have a Jade Black edition, made HSPL, tried some cooked ROMs (megade, pdaviet, spacejade etc), but i have the feeling that battery lasts much more with the stock ROM, with cooked ones it drains faster, am i right?
Can someone move this to ROM Development section, cause here i dont get replies, i think there will be more effective to discuss this
yes, i share your sentiment. my jade's battery drains faster with the cooked ROM. could it be an inherent symptom that exists in WinMo 6.5?

I dont know buddy, with most of the cooked 6.5 ROMs battery goes faster than with original ROM, at the moment i am using "pdaviet V24" and i can say for now battery is good
Hi buddy, i am now using pdaviet's v27 ROM. the battery draining problem is apparent. i have turned off 3G signal (since i dun really need that) and am using GSM only, this prolongs the battery life. hope a newer version of the ROM will solve this prob.
It prolongs but not so much of a difference. With the stock ROM i had 6 days of battery, with pdaviet i had 4 days without using WiFi or GPS, so i returned my stock ROM and waiting for another cooked one with long battery life

six days? how is it possible? full charging of my jade lasts for max 3 days. no gps, no wi-fi, "receive incoming beams" turned off.
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.

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?
Over the Last couple of days I have been using the stock MIUI rom, it ran supurb and very fast and stable and with the gingerbread theme for MIUI it looked very nice. And battery life for me was incredable using it normally like I do and at the end of the day maybe be around 55-65% left.
I now have moved onto the CM7 rom as wanted more of a stock like phone and read it is very good but from full battery within an hour it is almost 30% BT is not on as know there is a common no sense rom issue.
Although this is easily fixed by just switching back I wandered if anyone knew any stock like roms with good battery performance? or should I just stick with miui?
Im using a Euro HD2, and think its the 2.15 radio
You are using HTC HD2?

You are using HTC HD2? If yes, it's normal. Almost all android roms draining batteries very quickly... And MIUI drains the battery additionally...
I do realise that the MIUI roms drain the battery lol only at a much slower rate all my question was, is there a stock rom that drains it at a similar rate so it lasts say a days use instead of an hour
Also why are the CM7 mods the worst offenders at the min ?

go to market, and download currentwidget. put the phone on standby (turn off BT and GPS) let it sit for a minute, go to currentwidget and see how many mA is showing. if it's 3-7mA on standby, then it's normal.
You should try get your hands on MDJ's Cyanogen Mod 2.6. I thought that had great battery for a CM7 ROM. You won't find it here on XDA as MDJ's work is banned but a little google should do the try.
It comes with the stock launcher but it's pretty easy to download your preferred launcher.
Hi everyone,
I have a big problem of battey usage on Android...
I flashed the NexusHD2 rom in a first time and i realised the battery life was very bad ! (I lost 3% for 5 minute of use !)
I flashed the famous Typhoon CM7 rom and it's the same...
My Radio is 2.15.50.14 and i use CLK.
Thanks for your help
Try a different kernel. That helped in ICS, so after some trial-error you should find a good one.
Sent from my HTC HD2 using XDA
What kernel is the best for it ?
I use Hyperdroid w/ seader r9 kernel. I get pretty decent battery life with it. But you also have to remember that the HD2 is a bit older so it has a smaller battery and less power-efficient parts.

Agreed, i flashed STOCK Windows Mobile 6.5 from T-Mobile and the battery lasted exactly the same time as with Android on it. I found that the ROM/Kernel combinations only matter a little. The phone alone has horrible battery capacity.

A bit?! Lol that would obviously help a lot. I'm not quite sure how accurate CurrentWidget is, but in terms of standby battery drain I get 5ma drain with wifi on on my phone. On the same settings on my Mum's Desire S she gets 26ma. However she gets great battery life, which I would only guess is due to the larger battery (and the fact that she barely knows how to use the phone, so the screen isn't on very much at all).

I use batterymonitorwidget pro. And i get around 5ma with wifi and cellular on.
Try using an app called JuiceDefender - it works really well at extending battery life. It basically lets you tweak loads of options to do with data and syncing, so you can have it set that data doesnt run when certain apps are open, or data is off when the screen is off, etc.
There's an ultimate version available, but it is £4.99 from the play store. But I guess that'd be cheaper than a new battery?
The same problem occured to me a few weeks ago. I have been using HyperDroid-CM7 which worked quite decent for 5 or 6 months and had very good battery life. ABut a few weeks ago suddenly the battery life became to awfuly decay, wasting 20% of the energy for idle hour instead of the normal 1-2. I changed the rom to the NexusHD2 ICS port and the battery life slightly improved but rhe problem stays the same. Could it be because the battery itself is broken or some software calibrations are needed (I haben't done any for an year since I bought the device)
