Battery starting to put off my HD2 love :/

Hello..I am an overall very excited HTC HD2 user but i am having huge battery problems which is why i am asking for your insights In general if phone is idle it can go as far as 35 hours straight without any charging.But when i start playing around with it, browse menus , look through settings,launch apps e.t.c the battery drains like mad..sometimes even 3% in 10 minutes..
i do not know what could be the cause of this in particular since listening to mp3, watching movies does not chalk down too much power,i can even say i was slightly happy in that area(consumption and quality wise)..
so far i have done the below..
-hard reseted
-got a brilliant new mmc (transcend 8gb class 6 FTW )
-flight mode only during nights
-bsb tweaks
-some of the tweaks mentioned in the registry tweak for battery thread (not mmc ones, read alot about data corruption risks)
-tested battery (output voltage and mah are fine and it only gets warm after 3 hours of constant ndrive use-which is normal)
-i never installed anywhere else besides phone memory(apps/games)
-virus free
-i have no data plan so 3g/hsdpa access is not a possibility(also deactivated all connections from NoData app)
-disabled all auto update app functions(weather,footprints, my location ,time e.t.c)
the only possible deal i can figure out its to blame is the radio rom..
As i said earlier i am very interested in hearing your thoughts,comments,suggestions on my issue..Thanks for hearing me out
specs
manila : 2.5.19211619
Rom : 1.66.482.1 (gr) - official
radio rom : 2.06.51.07

do you use msn live?

i have the SAME EXACT problem, i do NOT have any apps running, i always use cleanram, every apps always get terminated.
as soon as i TOUCH my phone, the battery drains, this battery is rediculous, i have BsB tweaks with powersaving, i dont beleive how you guys get a full day out of this crappy battery when mine doesnt last 10 hours with just texing/and web browsing. im on my third battery replacement, i conditioned my battery three times and STILL the same problem, i feel like braking this phone in half, im using my blackberry bold 9700 now which lasts me 3 days with FULL usage ALL day, my hd2 is about to see the hammer soon

try flashing it to another rom
I stepped from stock rom to artemis and I use my HD2 often but with the stock rom i didn't even came to the middle of the day but with that artemis rom i can get till next day morning without charging plus it's very stable and i almost never do a soft reset and i use this artemis rom about a month now and i didn't even do a hard reset after flashing
sorry for my english hope you understand me

My HD2 will last 2 days constant usage. This includes web surfing and emails being pulled down all day via exchange.
The battery goes down quick to about 30% and will stay around there for ages.

I hear good things about artemis as well but i am afraid i am not up to the flashing challenge..too much of a chicken to play russian rulette worth 680 euros :3 (in case i break something)

just for a test select sign in with a different account so it wipes your details amd reset, use your phone normally and dont use live see how that gets on.
I had my phone running for 2 - 3 days of medium use. as soon as i signed up for live it was lasting less that a day even if i used task manager. I then wiped my details then it was back to normal again.

With Artemis you can hardly go wrong. It does not flash your radio only the OS part, you do not have to use HSPL but SSPL which is far easier to perform. It's all explained on the Artemis thread itself: http://forum.xda-developers.com/showthread.php?t=612580
regards, Kuzibri
BTW, if anything should go wrong, almost impossible with Artemis ROM's, then you can always flash back one of the original stock ROM.s from HTC itself (1.66 or 1.72)

hmmm...this is actually interesting...the artemis post seems to be fairly close to stock rom...BUT..if i backup all stuff i got now, will the usual apps (spb backup e.t.c) store everything?like e.g pc imaging apps(acronis true image , paragon drive backup) ? and if they do...and something goes wrong i can restore from pc even if hd2 becomes unbootable?
i really wish there was something simpler than me meddling with flashing :S im more into-system knowledge oriented guy :S

I understand your "reluctance" to flash a new ROM, but to be honest if you go wrong with flashing Artemis Rom, you will probably never will be ready/equippped to flash a new ROM. Flashing a Artemis ROM is as easy as it can be!

mine is set to 30% and with auto backlight off..its the ideal for my taste actually, even for the sunniest mornings
The WLmessenger change did not bear any fruits..i squeezed out all its batt to just see any time difference but nada..
Oh well, i might probably have to get over myself and start the flashing frenzy(i hear its quite addicting )
Byt the by , there is supposed to be a WWE version of 1.7.x this month i believe..maybe i will start with that and if it gets me nowhere Artemis here i come!

i'm just waiting for a 1500 capacity battery... which is all i need...
running full power and and heavy use... i manage to make it home to charge... but still... i would much rather have a bigger battery to avoid some worrying...
1500 would be soo perfect.. that accessory alone would add an extra 3-4 hours of life on my phone.. which would be more then enough...

Hopefully it comes out soon, but I'm tempted to try Artemis at the moment.

By the way i have 1 weird question about all those ROMs..Are they created from scratch from their makers or are they just modified/edited/tweaked versions of the original OS (ROM) that shipped with the phone?

I ordered a battery bundle with a wall charger, 2X1200mh batteries and a Mirco USB wire for $14 bucks. This is my first full smartphone so its hard for me to get used to the battery life.

I turned off all communications to flight mode. Yet my HD2 battery power keeps dropping fast. I dont have this problem with all my previous windows phone. Whats wrong? I'm using factory rom

yea the hd2's minimal battery life is something that i never had to deal with before also... (i've owned other smartphones but usually could last 2-3 days with moderate to heavy use...) but then again.. i never had a smartphone like the hd2 before
regardless... i'm not sure if i'd be willing to carry 2 batteries around with me... granted i could just leave it in my car until its needed.. but i guess i just consider it a extra thing to remember before i go inside my house/ an extra step to complete before i sleep... would much rather have just one 1500mh

Battery Drain
Do you guys experiencing battery drain have Co0kies Home Tab installed?
There is a known battery drain issue with CHT if .NET version 3.5.9198.0 is not installed. The battery drain will disappear when 3.5.9198.0 replaces .Net 3.5.7xxx.
Don't forget to update the registry to activate the new version and deactivate version 2 or earlier version of 3.5!
Co0kieMonster said:
Some users have had trouble with the battery drain.
I've now added this solution to the first post.
About battery drain:
There is an incompatibility with older versions of the .Net framework that can cause the battery to drain too quickly.
If you have this issue download the latest .Net version from here and install it on your device.
Even if you don't have the issue, it's always good to have the latest .Net version installed.
Big thanks to mike2nl for providing this solution, and to MichelDiamond for tracking the issue while I was away.

Do HD2 Batteries fail quickly when they go?

I've always read the thread about battery life problems on here thinking "Thank **** mine doesn't have that problem" - luckily since I bought mine in December the battery has been quite impressive really.
But a few days ago it suddenly started losing power VERY fast. I'm talking about 10%/hour even on standby, so I undid changes I'd made recently and it made no difference.
Then I read through loads of other threads on here from people who had poor battery life on their phones to look for clues/solutions.
It seems that the responses are (understandably) fairly consistent, eg:
check for stuff running in task manager
remove changes recently made to the phone/uninstall recently added apps
make sure your data/wireless etc isn't doing stuff it shouldn't be
turn off automatic updates
turn down the screen brightness
check activesync
do a hard reset
upgrade your radio rom
etc
All of these of course make sense and are useful suggestions, but it seems there are a good few cases where doing these things don't help, ie you check out the different potential causes and none appear to be responsible. And in the case of sudden poor battery performance you can't point the finger at the rom/screen brighness/auto updates if they are only doing the same as they have been for ages without issue.
So is there a genuine case for the batteries just suddenly 'going weak'?
I've resorted to a hard reset on mine last night after assuming something had got corrupted hence why I could not find the cause of the sudden battery weakness.
But it hasn't helped - it's still dropping approx 10% each hour while on standby, even on a basic install, without even all the apps I normally have.
To me therefore it logically has to mean a failing battery if a hard reset does not help - or can anyone argue why that might not be true? The only exception I can think of realistically is a hardware fault with the phone.
Have ordered a new standard one anyway, and a hicap 'bulge' battery, so I'll post up if the new one cures it. Quite a few battery threads seem to have no conclusion, so ultimately they're not all that helpful in those cases.
How many other people have had issues like this where the battery life has rapidly gone downhill and a new battery has solved the issue?
Also, has anyone done any tests on their 'dodgy' batteries to see if they are indeed going bad or if it's the phone at fault? For instance (really basic I know) if I were to hook up a light bulb to the battery and measure how long it lasts before it goes dim, then compare it to the results from a new battery, would that be worth trying?
If that's the case it's p1ss poor that a state of the art phone can't even go 6-7months before the battery is junk!
I understand and appreciate that li-ion cells only have a certain number of charge cycles (like most rechargeables) but this takes the cake!
My old XDA orbit is years old, still has its original battery, and that has not deteriorated by any noticeable amount, so these shouldn't either.

See: http://forum.xda-developers.com/showthread.php?t=688496
and let me know if the new battery fixes the problem. I think the batteries might be crap and prone to failing early.

Thanks for the link - sounds exactly the same as my issue.
Hopefully the new battery packs will sort it but that's shocking quality control or product design/testing if these are failing so quickly.

Yeah right. But that has not solved the problems with the 6 month old phone.
What i have not read in the post of Cret is that you took the memory card out and see if that improves battery life. a corrupt file on the memory card causes a huge drain.
try because that also happenns suddenly e.g. after been connected to a computer and not disconnecting properly.

That's a damn good point actually - thanks. I had seen that mentioned in other battery threads yet somehow completely forgot to try it.
I will try and see whether it makes any difference - cheers.
If that should turn out to be the cause of the problem how do you resolve it?
To elaborate - I don't imagine you can easily identify which file would be the culprit, without formatting the card and adding the files back one by one and testing for the fault to re-appear. That's totally impractical, almost impossible with the number of files you can fit on a 16gb card, and the time it would take to carry out that process, so what do you do?
Or is it possible that simply copying them off the card, formatting it, and pasting them back would somehow resolve the issue.

Doesn't this usually result in filesys.exe spiking up to 100% (or just high) CPU usage, though? It isn't doing this on mine, although I'll give it a shot without the SD card. I would expect better battery life without an SD card in anyway, but nothing dramatic.
Cret, let me know if your new battery sorts the problem so I know to buy one myself!

What are you talking about? Again, you enlighten a thread with useless information. You can clearly see the OP has had the phone for 6 months (as have I) and the battery is failing (as is mine).
Plus, your battery must defy the laws of physics if it gets better day after day. Interesting.

What you can try is put the memory card in a card reader and run checkdisk on the card. see if that identify's any problems on the file system
beside of that it seems that the HD2 has problems with 16GB cards, at least quite a few of them. read through the posts.

Id suggest to collect more data about the problem.
The program BattClock lets you check the battery drain in mA. A normal drain for the HD2, with no processes keeping the CPU awake, is 4mA in standby, with only the radio being powered to receive calls.
So, since the battery current value isn't update instantly, right after you wake up form stanby battclock should be showing 4mA (max6-7mA or something lik that) fora few seconds. If that's not the case, and if the drain is way higher than that, then it may be the case that the phone for some strange reasons is draining more current than it should, and it's not a real battery fault.

I had a similar issue, solved it by disabling auto backlight. Set it at 30% and all good since then.

Well, I thought there had been a slight improvement over the weekend with this battery issue but this morning on standby the phone dropped 3% in a matter of 5 or 10 minutes on standby.
So I removed the mcirosd card and in nearly 3 hours since then it has dropped another 4%. That's a big improvement and does hint that the card is the fault, but it's too early to be sure about that. I've put the card back in to see if it begins to drop fast again. If so I'll take it out for longer and monitor it again.

Good idea. I wasn't aware that the phones had problems with cards this size. What about with 32gb ones (not that I can afford one!)?

I did use battlog briefly, but just to keep an eye on the current current amount in use and it was fluctuating a lot just with the phone awake but running no apps. Sometimes it after waking it the phone would show a low figure like you quote but other times not.
I haven't checked batlog out fully in terms of what it's capable of, but what would be great would be an app that can log the current use like that does, but at the same time also log a list of which processes/services/applications are running, then that could REALLY give some useful info.
Eg the log shows normal current use, then spikes upwards when a specific process begins to run.

make a request for this feature in battclock's thread
The author seems to be quite open to useful suggestions (I, among others, suggested the log-to-txt feature )

Would be a good idea - I like BattClock I must admit. Nice to have the taskbar info like it does.
Ok, later on in the day, it's worked out that it's used 35% battery in approx 3.5 hours of standby - pretty horrendous. Equates to about 10.5 hours (very roughly) battery life on standby. I've checked periodically during this 3.5 hour period and the drop has been steady.
With the card removed, it went 3 hours and only lost 4%, meaning approx 77 hours of standby time at that rate.
Quite a difference between the two.
So at this point it very much looks like there is a fault relating to the memory card.
I'll try some testing tonight. Mainly that will mean I'll first do a filesystem test as suggested. Then delete all the media files, cut the remainder of files and paste them elsewhere, format the card then paste them back, and see how it then behaves.
So it seems now that buying new batteries (and almost slagging off the HTC one) was slightly hasty, but they'll still be really useful, so I'm not at all bothered about that.

Try putting the blank card in, with nothing on it. Would be interesting to see how much juice it draws just having a card in there without reading anything from it.

I have the same issue.
My HD2 worked like a charm, only around 12% battery drain in 24 hours (I could carry it around on standby for one week before recharging).
Now - it sucks around 3% per hour. After one day, I'm at around 25% charge
At first I thougth this was related to Co0kie's Home Tab, but even after hard-reseting, it still drained battery as hell.
At the moment I'm running it without memory card (4GB Kingston) to see if this might be the issue...

I've run a CHKDSK on my memory card just in case, but the filesystem's fine. Any update, Cret?

Well, I'm sure mine was caused by the card, or at least a fault that related to it (ie possibly a file rather than the card itself).
Since I removed the card the battery life returned to normal, so I formatted it, and then copied some of the content back onto it again. It has been back in the phone for a little while now and has been behaving quite well. Basically for instance it's at 77% now at 10.30pm after being removed from the charger around 8am. I haven't used the phone much except to check emails a few times, read a few texts, and go online a couple of times/read RSS feeds a little.
So I'm fairly happy with that.
BUT - not having had the chance to use the phone much (ie mess about) since I formatted the card, I just found that the phone thinks there is no card inside it at the moment for some reason!
I removed it and the PC can read the card and its contents no problem but the phone cannot see it. The only reason I can think of for this is that I formatted the card as NTFS instead of Fat since it's meant to give faster performance, but is it possible that the phone itself does not support this format?
Since it's not working at the moment I'll have to try wiping it and changing it back to fat again.
Yes I have tried rebooting it also.
Next thing is th double size replacement battery I bought arrived the other day. The battery fits ok but the replacement cover that came with it does not fit properly at all.
The cover clips in ok on the side of the volume buttons, but no matter what I do it just hangs loose on the opposite side so I can't actually use the bloody thing since the battery will just fall out like this. Really not happy at all about this.
This is the one I bought:
http://cgi.ebay.co.uk/Extended-2400...eBatteries&hash=item5d2925ce91#ht_1862wt_1137
I think I will be trying to return this for a full refund since there appears to be a design flaw. Normally I would attempt to make something like this fit properly myself but if I failed then I'd have a piece of junk that I could neither use nor return so I think better just to return it without messing about.
It's a shame as the cover actually looks like it should fit perfectly, and seems to fit very well, it's just that it fails completely to latch in place on one side, as if the clip bit is not long enough perhaps.
What concerns me slightly at the moment

Just reformatted the card as Fat instead of NTFS and loaded my files back on and it works now.
So I'll update in due course once I've been using it loaded up again.

[WP7] The two ways by which you can get awesome battery

So you did flash, and you are running WP7 on your HD2.
Now the battery dies quick?
Firstly, download this ROM and flash it: (google your ass to find out how its done, dont ask me )
http://forum.xda-developers.com/showthread.php?t=941905
Its a custom ROM by football. Works amazing. Better than original ROM or the Moonlight (another custom rom) shiite you're planning on running.
After you have this ROM (or even if you dont have this ROM) if you take care of the follwing things, you will get HUGE battery life.
1. Fix the indicator by installing Registry editor, charge your battery to full and follow following steps:
http://forum.xda-developers.com/showthread.php?t=933751
Thanks arkatis!
2. See that you have a new sd card, not the one which came with your hd2 orignially, buy a new one, any branded one should do, and rplace it with the older card and in your phone go to: settings> about phone> hard reset
These two steps will really show a massive imprvement in your battery life.

Are you able to list even one of the performance difference's between this rom and the Moonlight rom?

well, for astarters, ml has a higher call drop rate, the voice quality over the call isnt all that great either, im on x.12 radio, and its not able to use the radio perfectly - this same problem is not there on footballs rom.
Another bug is while recieving calls, sometimes, when you click "answer" it automatically puts you on speaker phone! Its scary when you dont want others to know who just called. (happened twice on ml)
gps lock took nearly 5 minutes on ml, on footballs rom it snaps on in less than 30 seconds.
thats why i had to switch to hd2 1.00

Odd how I haven't had any of those problems. Anyway there is no difference between this rom and footballs rom. The tools to make any of those kind of fixes aren't out yet. The only kind of change you'll find is simple things like different keyboards or installed apps.

I did both, but there is no improvement in battery life. lasts less than 12h as before...

I will try the hard reset part when my new SD card arrives

Hold on there a sec, top be clear buying a new SD card might not work at all!!
If you dont have lots of cash or you dont have another use for the SD card please dont go spead money on something that may not work!
Not all cards, even within teh same brand and model will work!
and the reg fix doesnt improve battery life, it just lets you know what you have left, most issues with apparent high consumption are because a your phone isnt fully charged yet windows reports it so, apply reg fix once charged, restart and charge again you may been to repeat process, and to check use the HYC battery tool, try it pluged in and unplugged and you may notice a difference, if you do, restart and plug back in again to charge the remaining battery

I am using Moonlight atm..and with calls/sms and wifing i get utleast 1 and a half day..I use my tweak everytime i charge the phone and seems alright!
I am so obsessed with WP7 so i maybe get an official WP7 mobile..i am thinking of Omnia 7..Looks good!

I actually got the best battery life with the card that came with my HD2.... I've tried 8 different cards with wp7, too... most of them bought recently. Just buying a new card doesn't mean it will work with WP7. Your best chance of getting a good working card it to get a class 2 sandisk with part# ending in A11M.

I only seen this now! This just proves you haven't a clue what you are talking about!!

I'm using the Moonlight-Rom and I tried the last Radios (2.12, 2.15, 2.14)
And the winner is 2.14 - used the phone a lot (games used Wifi...) and after 12h I've still 25% left.
With the other Radios I had to charge it after 9houres because it ran out of battery without using it that much only some SMS!

Hey,
at least we could talk in german, but the others should be able to understand our conversation
I also tried many Radio Roms and my fav is 2.12, bu to be honest I only tried 2.10 2.12 and 2.15.
Do you really think, that the 2.14 is better than the 2.12?

Ja dann machen wir das in deutsch... ;-)
Yes The first Rom I tried was 2.15 (it was already installed - previous rom)
Then I read that 2.12 is working very good and because my phone needs to be charged after less than half a day (using 2.15) I tried 2.12 - but I still had the same problem.
Thats why I decided to use a other Radio! And it seems to work!
Maybe it depends on the phones too?
I dont't know - Try and Error....

I too don't think the registry battery fix works. First time I ever installed WM7 ROM was football's and never changed it. Tried the battery fix a few times with no luck.
Had Radio 2.15 and downgraded to 2.12 with no luck. I see some have improvement with 2.14.
I took out my SIM card yesterday to try if SD card "helps" in battery drain. Left wifi on and played with internet for a bit. This morning it had like 90%+ battery left in it. So it's not the SD card. IMO Radio is the major culprit for the battery drain.
I'll try 2.14 tonight.

That is what I am feeling too! In an other forum I read, that it could be helpful to release the battery for 60s before charging it. But I don't want to do this every time I charge my phone

Right, tried that too but there are no changes and if I check the battery with the HTC battery tool after charging it is 100% charged....

HD2 HUGE BATTERY DRAIN 1% every 1 minute

Hi my hd2 is on a stock windows mobile rom and has a huge battery drain, every 1 minute or so i lose 1% of my battery and even on standby its the same.
Please can anyone help!!!! I have just flashed a stock rom from sd and have nothing on it and it still does it!

did you flash another radio rom? battery performance has a lot to do with it.
formatting your sd card could also help.

I've tried formatting my sd card and have tried flashing many radio roms right now im on the latest one (2.15...) and still it does it.

well the latest doesn't mean that it's the best for you. it depends on your carrier and area. but this wouldn't result in such a high battery drain.
sorry i can't help you then. i would try to make a freash install with task 29 and everything and if it's still not better try another battery.

Ive tried everything..no one knows anything about it
Thanks anyways
Would appreciate if anyone else has this problem too?

Sounds more like your battery is on the way out. Do you have another you could test?

Yupp, i have 3 standard htc batterys and 2 of them are brand new and still it happens

You did not say how long you have had the HD2, whether this problem has occurred from the beginning, or had just recently started. If it's been that way from the time you got it, it needs to go back to the vendor/seller for replacement. If it has suddenly started, what has changed? Other recent threads here note that a change in GMail was causing problems with high CPU levels and fast battery drain. I believe you said in one response that two of your three batteries have this problem. I assume that one of the batteries does not. If so, it sounds like bad batteries.

Sorry i meant to say that every battery that i try, it still has the problem. And also i brought this phone (used) with no problems and i put android on it, one day it turned extremely hot whilst i put it on charge, then what used to happen was whenever i left my phone on standby (screen off) my phone would switch off. But then i changed my charger cable and that problem was fixed but now i have this problem.

In that case could be the cable not supplying enough charge to the battery, or the phone reading battery stats incorrectly. Other than that I'm at a loss.

Tried everything :/
Thanks anyways I guess its just time for the bin :/

Are you using Gmail? There have been a lot of reports about overheating and battery drain from gmail accounts. Evidently there was some change in the way Google handles their accounts.

Nope, not using gmail
theres nothing on my rom as i just flashed it.

if you flashed it new and the problems started at this point you can try to wipe the battery stats in cwm. don't really now what exactly that does but it's worth a try.

thats providing hes running it and not using a stock winmo 6.5 rom

Yeah, im using a stock windowsmobile rom so no clockworkmod unfortunately..

oh right. there was something with windows on this phone ^^ sorry already forgot that.

Hi, did you try the following?
Switch off the phone completely and then remove the battery for approx. 15 to 20 seconds. Then put it in again and start the phone.
When I used this procedure the battery drain was normal again.
BR rainer

tried that still no luck :/

Take out the sim AND sd card. Maybe one of them is going bad.

[Q] Battery Drain VS Rom?

I know theres alot of topics about battery drain, and some methods have worked for some, but I am still stuck in the loop.
I'm using Back to the Future (XBmod-Yuki/7740) - and have tried The Camera Trick, 2.12 Radio, and Registry tweak (battery indicator) and all have failed, i get around 8-10 hours battey on minimal use, (Facebook app for 30min and 8/9 text msgs) [note: 3g and Data on]
and I was wondering is anyone noticing any difference on other wp7 roms? or is that rom specific?
Thanks in advance

Apparently i've got the same issue as you, I got 3 hours off it with intensive use today ( 2.12 radio, no battery fix, but it was draned down to zero )
I'm also using the back to the future rom ( But it's registered as 7720 )
My device is eastern europeian.

I'm back on winmo
i will try wp7 again (HD2O) (7740) but with different SD cards, hopefully i get a lil better life
ill let you knw how that goes

And i'm gonna get an android SD these days to compare.

with lightly use, my HD2 WP7(Back to the future 7740) ate battery so quick. I'm trying to flash pdaimatejam's v2. Hope to get some changes.

Okay to CONFIRM
Booted pdaimatejam's v2 on lexmar 8gb (class 4 )
Radio: 2.12
and so far used 10hours
and still 54% battery remaining
3g and data is ON!
Location OFF
Live Tiles disables (have to manually update hotmail etc, no push)
Tooks round 40pics, used FB app (Biggest drain)
and few small video clips (2.mins each)
also 70-100 txts snt and recieved
im happy now

yeah i was struggling with battery life for a while too.
the camera trick seems to have helped a lot. i get almost 2 days with normal use with location, 3g and data all turned off. i am going to do the registry trick, then turn location, 3g and data back on to see if anything changes.
EDIT: the registry editor that works with mango does not allow me access to these registry files. oh well.

Android SD was still not the best I've tried. while the ROM had more battery life then yuki's back to the future, it still left me 30 minutes before I was ready to let it go.
Today on WP7 i got 3.5 hours with: the camera trick,(Switch to video and leave it running, right?) also no 3g no Wi-Fi and no Location/Bluetooth. Brightness all the way down ( snowy weather ) . Where can I find the instructions/guide to installing pdaimatejam's or is it included in the download?

Do we have to use camera trick every time we reboot HD2? How about the reset command from MDLDR menu? Do we need use it every time we replace battery?

reboot should be fine, bt i tried the HD20 rom over last few days (radio 2.15) and battery drain whilst standby is AMAZING! with 3g on over night it drained like 5-7% battery, but when using browser, whats app etc battery drains too much :S
