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 would love to know what your settings are, after 3 hours lite use i lost 45% battery, my gps is off and background update is also off....
2.12.50.xxxx radio.img
it has a lot to do with radi youre using, i found this one really good, have good bttery life, 3g, hdspa, wifi, gps, mms and all working really good...
Hello to all, iam using the android shubcraft version on my hd2 and i cant charge my device 100%. It stops on 85%. Did you guys have an idea??

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.
WP7 Battery Drainage Vs. Radio Rom:
After searching in Forums, I Found that most of us (WP7_HD2 Owners ) have a great issue with battery drainage.
I also found that some of us tested radio roms and found that it affects the drainage directly but not the same way the same version did on WM6.5.x
SO I wanted to create this forum to brain storm and try several radios and check what is the best for our Beloved HD2
I will post and edit the best radios based on your reviews so more you post results more we will get clearer image of what's optimum:
So Based on what we experience ; Radios are sorted Best on top:
1- Radio 2.12.50.02_2
2- Radio 2.14.50.04
3- Radio 2.15.50.14
I know it depends on your network provider also, but At the end it's kind of trial and error forum, we get help from each other: there is nothing certain 100 %.
Rest will follow...

Maybe radio 2.12.xx.xx should be tested also. It is a 576mb enabled radio also.
i've tried 3 radios so far
2.12 is the best, and 2.14 and 2.15 are very similar
i am testing 2.10 now
im using htc hd2 t8585, not tmous
i am using the 2.15,,works normally,, not bad,,but neither remarkable.
Managed to pull 30 hours until recharge with moderate usage on 2.12.50.02-2 radio. UK Virgin mobile' s best radio I might say when it comes to batery drainage.
Sent from my HD7 T9292 using Board Express
I have radio as 2.14. Would like to know whether the radio 2.12 is better ?
Wrong forum, this is is development not Q&A/General
Doesn't location also have to be taken into account? I understood that a radio that gives great performance in the UK could be terrible elsewhere and vice versa.
I'm not suggesting that this thread isn't a decent idea, just that users should also post their country of use.
I tried WP7 with radio version 2.15.50.14, the battery lasts two days, vs windows mobile 6.5, 5 days.
But my opinion is that the problem is a bug that allows the use of gprs/3g link cause some sort of continuous, although the 3G connection is switched off.
Im using Radio 2.12.50.02_2 simply because I seem to get a better signal with it. Ive not noticed much difference in the battery life than when I was using Radio 2.15.50.4
Just added it here because it discuss the topics mainly accessible through development, and want most of us to reach it....
I have switched from radio 2.15 to 2.14. and I see improvement in battery life
Sorry if this is a bit off topic but it's just something I experienced that might be found useful....or I may have a freaky battery
Could the problem with the battery drainage could be related to the battery state when WP7 was installed?
I installed it on my device when the battery was half charged and I was only getting 1/2 a days use before it died. When recharged under WP7 it would take 1hr and only last another 1/2 day...but.........I installed android and am now dual booting WP7 and Android.
I ran the battery out using Android and recharged it under Android to 100% charge. Since doing this WP7 takes 2 hrs to charge instead of 1hr but the battery lasts all day with between 5%-15% remaining after 12 hours.
Maybe WP7 checks the battery state on install and assumes its fully charged when the device (HD2) is first powered on and incorrectly calculates the maximum charge!?
Just a thought.

I believe you are right. For the first time did y HD2 chage under wp7 and i noticed that the battery did not last half a day. I usually charge my batteries through an external phone battery charger (have 3 batterie which i rotate).
I am trying 2.14 in London Uk. So far better than 2.15. Will try 2.12. I remember there was one radio in particular that was FAB for battery life but so so for reception. I will try to find out which because for me battery life is more important. Could have have been evem 2.12. Will have to search the other forums.

You might be on to something here! I charged my phone to full capacity while downloading and waiting to install WP7 and my battery had been good. I even believed that it holds better than with android builds on NAND or SD. Lets investigate this, please.
Radio 2075027_2
Ok I managed to find the radio that gave me excellent battery life under Windows 6.5 rom = Radio 2075027_2. I reasearched my old posts in another forum.
I have installed it fine and will test out over the next couple of days and report back.
If anyone else wants to try, the radio is in link below:

Remember, just a warning for everyone.
If you use a 2.07, you want be able to boot into Android (if you dual boot using MAGLDR SD card).
Android needs 2.08 and up.
i tested 2.10
it is a little bit inferior than 2.12 =) but it is still great
I'm on Twilight DFC ( last version with htc hub )
Rom use : 2.14.50
HSPL : 2.08
card SD : micro SD sandisk 4Go class 4
Magldr : 1.3
Use : no really ( check my mails every 3 hours , 20 sms per day , little internet with 3g.
Désactivated : my 3g, wifi, localisation for a better battery level. My emails are checking just every hour by option.
Results : 100% at 8 A.m , 20% at 7 P.m ...
The battery are very drain...
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

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.
I got my HD2 about 2 months ago, I installed MIUI on it the day I got it, and for some reason the battery life is absolutely atrocious.
If I even lightly used the phone at all within 4-5 hours it would be completely dead. Since I bought it refurbished I thought the battery could be old, so I went ahead and a bought a couple of new batteries. Same problem. If I want to use the phone at all anymore I need to bring the brightness to 0% and put on airplane mode.
I think it could be a MIUI problem, so does anyone know of a really good ROM for battery life? I have Android NAND.
Also I keep SetCPU from 225-998 with the smartass governor.
I've also noticed that if I leave my phone in my pocket for a few hours, it gets really hot.
Any ideas?

You should task 29 them flash everything again with formated SD card and use Wipe battery on Recovery menu or use Battery Calibration on Maket.
I and many people use MIUI ROM and don't have Battery issue
^Okay, I'm not sure how to perform a task 29 but I'll do some googling and I'll format my SD Card and do the other steps.
Another thing that I notice; when using the "Current Widget" app, I notice that in standby mode, by phone's current is 53 mA!
From what I gather, 3-7 mA is normal. Thanks for the info, I think a bad flash could be the culprit for my absolutely abysmal battery life.
EDIT: After a few more tests my standby current stands at about 2mA normally, but sometimes it can jump into 30-50. I'm still confused as to why my phone eats up so much battery!
try gomiui

You can try reflashing, or even try flashing a new miui rom if that's your taste, make sure you wipe everything SD card format etc.. charge battery to 100% also. You can also try setting airplane mode then rebooting. Or possibly you have an app or widget eating your battery. I personally use hyperdoid and get about 12-16hrs on it depending on how I use it, my experience with miui I had about 6-10hrs

Try disabling background data. My normal standby drain with BG data off is 4-5mA, but it is around 20mA when BG data is on.
I've had my hd2 since it came out, and am a regular tester of various roms and windows roms. When i got WP7 nodo a few months back i noticed that my battery life was, well, terrible. After trying every battery trick, charging method, and the like, the best i could get out of my battery tool is 120ma, which is like 8 hours of charge for me (TMOUS, 3G on, ~30 minutes of gaming, ~30 minutes browsing, ~25 texts per day, ~30 minutes talking, wifi and background stuff off, brightness moderate).
I've switched back to android since, but i was wondering if those problems persist in Mango? I noticed the big dog, Cotulla, released a ROM and if anyone could tell me if the battery problem is fixed? If not, Whats causing the battery problems, besides the camera (idk if that was fixed, but it was a big problem in NoDo)?
Becuase i really want to switch back to Wp7, but that battery life man.....just can't live with it.
Anyways thanks y'all!
Exactly!
I've been using XBmod & Yuki's Back to the future WP7 8107 ROM, and while I LOVE the ROM, and having WP7 on my HD2, my battery life is TERRIBLE! I too have done all the posted "tricks", but I'm still charging my phone all day. If I can't find a way to increase my battery life, it'll be back to Windows Mobile 6.5.x for me.
I have approx. 2 hours of calls each day and with WM7 I must charging my telefon min. 2 times in one day. So its very horrible. Would be nice to find any fix for it
Batteryyyy!!!!
Hi people.
Unfortunately I'm not reply to give you some fix...I have the same problem and I' still waiting for a fix, maybe if we are more the fix come more fast lool
