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?

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

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.

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.

Hey guys. I'm a bit new to this, and I have a few questions. 1. Does having a faster microsdcard worsen the battery life of android running on an hd2? 2. With set CPU clocked back to 576 MHz Max 245 min, and all the settings toned back, I barely make it through a days use on my nexus one 2.2 build. Is this normal? Does battery vary greatly from build to build? Is there a build known for good battery life?

Android builds will always use much more power than WinMo, reverse engineering the drivers is not ideal nor efficient. Some builds use less power than others, best try a few with the current widget installed.
This is a thread on SD card power, I'm not sure it makes a huge difference. If you check the power usage app you will the OS is using 2 or 3 times the power that the screen is - this isn't good for battery life.
Hi lads, iam new to this myself I got my hd2 about 2 weeks ago and havnt had out of my hand since.. the only changes I have made was download hspl3 & flash radio 2.14 and I am currently running darkstones froyo 2.2 and I love it.. the only prob I had for my self was battery it was eating it.. when screen was off I was getting around 168ma and using phone was was up to about 600ma.. after about a week of searching I found out a few things and now I get a full day wit heavy usage. I downloaded setcpu,advanced task killer,green power free,changed a few settings on my phone and now I have a battery tats just as good as running WM.. ill get the exact settings up for u later if u want... hope it helps
after doing a task29, i loaded "vbn reloaded" (minimal winmo rom) ;
use EBL android loader and load mdeejay EvoSense 2.0 revolution ;
using "currentwidget" my battery usage is only 7mA idle with four email
accounts getting updated in the background.
Been using android as the (only) daily OS
z
ps just did a rm /data/system/batterystats.bin
need to see if it charges to "100%"
if only battery usage GOES DOWN WHILE ACTUALLY USING ANDROID,
that would be penultimate
(ultimate obviously is NAND boot )

I've been testing 2 different batteries fully charged with phone off. Using current widget they get the same readings about 7ma with screen off and average 200 on. One battery drains at about twice the rate of the other. Im pretty sure one is defective. I've cycled both to make sure. Also running on wm I get the same experience. If your lucky enough to catch a battery problem in the first 3 months of purchase from t-mobile they may send you another like they did for me.

heres a good thread on conditioning the battery
http://forum.xda-developers.com/showthread.php?t=827355
as far as sd card speed, a faster card will use less system rescources due to faster read/write speeds, ie: the cpu is under less load for a shorter period of time.
faster io performance = better battery life.
side note, underclocking to far will hurt battery life. this is due to it takeing longer to complete tasks. so if your like me and do a lot of turn the screen on, check some thing , turn it off, then the longer the screen's on the more your draining it.
I'm on Twilight DFC ( last version with htc hub )

with rom 2.15.50 it is the same
rom i have use : xmob 1.3 / 1.4 , moonlight ... and.. it is the same problem.
Please help me .
Same issue here. It's about 60mA battery drain, guess something wrong in power management.
You've most likely forgot to disable bluetooth completley. There is a 60mA BT bug in some roms.
bluetooth is off, but the battery running time is still bad. What Radio Rom is definitely the best ?
How to completely turn off bluetooth? It was turned off in settings
Yes, Settings/Bluetooth disable

2.12.50 with the battery tweak found in the development subforum gives me over a day with moderate to heavy usage (games, 3G internet, 3 e-mail [email protected] min, 30 min. voice calls). In standby (only mail sync on) I get 10-12% battery drop over the night.
Wait for a few recharge cycles and it will settle. At first I got 12-15 hrs. After 2 weeks it got MUCH better.
is your batter being charged propperly?
The battery tweak sets the full level for the battery.
you must first charge the battery to its maximum level then run the reg tweak
Now here is the problem, WP7 on our HD2 will not charge the full batter all of the time. Quite often you must charge until it goes green, then reboot and charge so more, keep repeating until the HTC battery tool reports the ACR level roughly the same as the FULL level.
to give you an idea
Ive just charged my phone over night, it says its full, it wont charge any more but the tool reports it only half full, even though the indicator shows full. But my battery life will drop like a rock and may report being empty when its not.
If i restart my phone just now the tool shows a jump in ACR value to about 800mAh it then allows me to charge the remaining 400mAh.
or you might find that restarting it shows the battery is full in both indicator and ACR value
The point is, after a full charge, restart the phone because until you do the phone doesnt appear to know whats goig on wth the battery, im guessing this is something to do with the fact that the HD7 and HD2 DO have some small differences inside.
I think what frustrates me more than anything else is the sheer unpredictability of my battery performance. I have done all the tweaks and installed the battery tool but overnight in the past week I have seen the battery go down as low as about 15-20% and remain as high as 80% with a range in between (estimated values, of course).
I'm now going to try to look at my data usage to see if anything is causing the radio to work extra hard some nights and not on others.
If it was at least consistent I could then start thinking about Radio versions, management strategies and the like but while it's so variable it a bit hard to get scientific with it...!
indeed it is a bit of a pain but remember we were never ment to have this ROM.
remember though it might be unpredictable because its not full, its not as easy as it sems to get a full charge, even when htc battery tool and MS tells us its full it might not be, persistant restart and charge usually gets it done
It is definitely battery problem exists! Don't try to hide it because all that stuff you are talking here to solve that is not working! Test in 2G network without any BT and WiFi during 24h failed, battery completely drained without reason.
no one is saying there isnt a problem, there are seveal problems
The big one is you shouldnt have WP7 on your HD2, our device was not supported, you cant say the HTC HD7 is the same because it is not, largely it is yes, but internally it has differences, one of these differences seem to be the controler for the battery
To be clear, WP7 cant report the correct battery level without tweaking it, and in some instances WP7 will not completely charge your phone but it may appear full there by leading to quick battery drainage
I second that. I think it's the matter of hit and miss. I have two hd2s, and one of them has ****e battery life. Both are using the same rom, same radio, same battery optimisation technique btw.
I bought an HD7 cause of the battery drainage of WP7 HD2, multi touching, downloading from market e.t.c!
I know HD2 is better than HD7 because you can have everything but... WP7 is my thing ya know??? So if you guys liked WP7 just go out there and buy your selves an official WP7 device! Believe me i l.o.v.e it and i will stick with it!
Battery life on HD7 is stunning! I have it running 3 days now and now i have 20% with moderate use..

Worse recommendation I ever saw. When first android port was released, there was huge battery drainage too but now I'm using android on my HD2 with 3 days batt life and I didn't buy new android device. So it can be fixed without wasting money.
In my opinion..Android is boring.. I know that battery life on Android HD2 is awesome but the OS is very Boring... When i flashed WP7 i said "this will be my daily OS" (i love simplicity..)... At that time i needed to charge my battery daily and i was a little bored of the hard keys and battery and stuff like that! (also i had some lost pixels on the screen) Didn't wanted to go back to Android though! So why do i have to keep my boring HD2??? Since i wanted to run WP7 as a daily OS i got my new HD7 (for 150Euro)
I am Just telling my opinion and i hope you agree with me...
I am a tech lover guy...Yesterday was iPhone, after that HD2,today HD7 and God knows what else for tomorrow!
where to get an hd7 for 150,- euro????? i'll going out and get two of them, too
for me wp7 is boring until now. almost no customization.. when you want to turn off data or wifi or bt you have to navigate through 2 or 3 menus.
and it is slow even though there are beautiful animations. (contacts open in about 2 seconds and in android it is about 0,5 seconds)
i am all for simplicity as long as you have all functions and speed.
btw battery is enough for 1 day with moderate use but forget using it from early morning and a long partynight
(camera issue still a bummer)
im all up for opinions on here....so ill give me own
Im sorry but i have not seen a more fluid and resposive device then the HD2 with WP7, iphone, android on various models even WP7 on other devices dont appear as quick as mine but thats the luck of the draw with using our HD2 some folk have had issues others think its amazing. contacts for me, around 200ish load instantly
luck of the draw
battery life is a concern still as is the camera other than that all is good

In my opinion..Android is boring.. I know that battery life on Android HD2 is awesome but the OS is very Boring... When i flashed WP7 i said "this will be my daily OS" (i love simplicity..)... At that time i needed to charge my battery daily and i was a little bored of the hard keys and battery and stuff like that! (also i had some lost pixels on the screen) Didn't wanted to go back to Android though! So why do i have to keep my boring HD2??? Since i wanted to run WP7 as a daily OS i got my new HD7 (for 150Euro)
I am Just telling my opinion and i hope you agree with me...
I am a tech lover guy...Yesterday was iPhone, after that HD2,today HD7 and God knows what else for tomorrow!

I'm not agree. You didn't notice that "super simple" WM7 consuming more energy than "boring" android? And what a point of this?
You know what, rich people always bored. I got my first iphone (3gs) just 3 month ago, and HD2 was like a gift from my friends in America.
Hey guys,
I am considering switching to WP 7.5 from WM (default ROM) and was wondering, will I see any battery improvements or it will actually drain it faster?
Also, anyone tried Android 4.0? All I care at this moment is battery life and don't mind whether it's WM, Android or WP.
Hi!
Best batterylife you will get on this device is with WM. Find the right release (some of them have improved power management) and stick to it! You will NOT be able to find better battery-life with Android or WP...

That's right. As far as I know, best battery life is with WM6.5. However, I'm really happy about battery life in WP7 (DFT Ultrafruit changing radios and other things). I make more than a day, maybe 2, but being careful about what I do, of course.
Maybe wm6.5 is better.
But I feel wp7 takes better pics.....weird...after taking 240 pictures of a book..the battery from 100 to 13...is this normal or power consuming?BtW,it's standby life can be as long as two days with some general use
Battery life w.r.t various ROMs are as follow
WM 6.5 (Best battery life) >> Android >> WP7 (Worst battery life)
WP7 runs constantly at 998 Mhz (One of the reason for high battery consumption) where as 6.5 and Android can dynamically vary from low CPU consumption to High as required.
Also in WP7 battery life depends on soft radio + hard radio combination.. For good performance with good battery life use 2.15.50.14 Hard radio + 5.50 soft radio.. For best battery life use 2.12 hard radio + 5.50 soft radio..
Trust this clarifies..
Very Low Battery Life...Please help...
Hello friends...
Recently I have installed WM7 to my htc HD2. I found that the battery life is very less.
I have read here that if we use the combination of 2.12 hard radio + 5.50 soft radio.
Please someone tell how to do so....?

Search the forum my friend, hardware radio is updated via the custom RUU, it does not delete anything.
Software radio needs to be built in to the WP7 ROM before you install it, changing this will mean a loss of everything
Now, whilst battery life is deffinitely less than WM, one thing i can confirm is that its not worse than android, the problem is that it doesnt always charge completely, so for example, it may say its 100% full, but its only half full, so it appears to drain twice as quick, or it might say its empty and its still half full.
It could say anything, for best battery life use an external charger. reboots during the day will help keep it reporting correctly. Tho even then ive noticed that it doesnt always work, some times you need to plug a USB cable in for a moment for it to refresh it.
In short, battery charging and reporting is all over the place, but once you get a full charge it actually lasts quite a long time with very heavy usage.
Personally, now that I've found a WP7 ROM that doesn't drain my battery in 5 hours, I don't notice a difference. (I'm now using pdaimatejam, BT on with -3 to -7ma drain in standby, Yay!).
Sure, WM will last longer. Sure Android will last SLIGHTLY longer b/c it doesn't run the CPU full speed when the display is on. And that is a clarifying statement to the above. WP7 does NOT run the CPU full speed all the time, only when not in standby.
Having said that, I get a full, usable day in WP7 with moderate use. I got just over a full, usable day in WM6.5, but I had to charge every night regardless.

Testing 2.12 now, thanks,
Now sure if estimated battery life is correct, before installing it said 5h, now 2h
also dont forget to try camera trick with combination 2.15/5.51

Does it work with 2.12?
Is 2.15 better than 2.12 in battery life?
10h standby (mail sync on) with all the tricks on HD2 2.12, bad
Hopefully, Tango will increase battery life.

you can dream.... but none updates for WP7 cant be increase battery life... only can be worse
seems your battery in bad shape or something do wrong... also if you play music few hours, play games, nothing strange if battery not least long...
with radio combination 2.15/5.51 + camera trick, with WiFi on 24 hours at day, my battery working around 30 hours with normal use
Hm, well, it said 2h remaining but still holds, another 6 and has battery left... No idea.
I will play with soft/hard roms after Tango is released, as now floashing and losing data for a month or two is pointless
Thanks!
I have actually had better battery life using Pdaimatejam ROM with radio 5.51T/2.15 combo than I had with Android or WM 6.5. Not exactly sure how but it is definitely the case if any of you want to try that
on my hd2 it feels longer with wp7 u can try it on your own
yeah

2.worse battery life,excellent speed=windows phone
3.good battery life and reasonable speed with freedom to do things that you cant in wp and wm=android
i prefer wp7 and sd android and i have to charge 2 times a day (ok i have 2 batteries and external charger so i change the old one and i am ready to gο) but i have a phone that i enjoy to use
