Battery Issue with DCD 3.01 - Mogul, XV6800 ROM Development

Ok heres my problem. After the phone reaches full charge, i would unplug it and within a minute it would drop to 96%. And from there on its downhill. I probably get 2-3 hours from a full charge. I have actually been having this problem from the 2.3.2 rom. Could this be a battery problem? or Software?

Forgot to put email notifaction

My wife and I have both noticed poorer battery performance since upgrading our Moguls' ROMs. Like you, we first tried dcd's 2.3.2, and now we're using 3.0.0.

I dunno, I'm finding mine has BETTER battery life now than it did with... whatever the last 2.x was I was using.

My battery actually seems like it lasts longer. Check that you don't have bluetooth or WiFi on and IR. You are letting your phone go on standby right? Another thing to check is your screen brightness.

hmm thats weird. bt wifi and ir are all off. im goin to turn down the brightness and see if that helps at all.

My battery life seems better, i wish i would have actually tested it. Oops. I'm using a rom from DCD's 3.0.1 kitchen.

Possible Solution...
Hey Guys,
I just upgraded to DCD 3.0.1 & also noticed the battery drainage problem. I wanted to see if the battery saver tweaks have been implemented on this new rom & sure enough they have not. I have been using the tweaks all day today & and only shows 15 percent decrease (10 hours of use so far). I also turned off GPS by way of settings-personal-phone-services-location setting-911 only. Turn it on when I needed it.
Here are the Reg tweaks:
Battery Improvement Registry Tweaks
HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms
Default value type and value are
DisablePowerManagement=dword:1
Change to
DisablePowerManagement=dword:0
HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms

HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms
Default value type and value are

Change to

I just flashed DCDs 3.0.1 and tried to change the Reg as you spelled out so well above.
The D values are already 0. He must have changed his ROM.

its been that way for months..

My battery is definitely draining faster then normal, and with nothing turned on. However, I have experienced this once before, it was so bad 30 minutes of talking on the phone would completely drain the battery. I was about to give up and assume the battery was toast, when I tried a hard reset. After that, life was back to normal, so I can only assume there was some app going crazy and eating up CPU so bad it killed the power.
I'm going to try a reset here myself, hopefully that will kill the problem.
-toonces

it should be noted some moguls come with 1000mAh while others with 1500mAh. check what battery type you have, maybe thats why its draining faster. there was talk on ppcgeeks about an 1800mAh battery for sale, but i dont know much about it.

Ditto the battery problems, had consumed 30% of battery in 4 hrs this morning after showing the GPS feature to co-workers.
I'll reset and try settings-personal-phone-services-location setting-off to disable GPS.
Are there reports of accellerated battery consumption with the Sprint ROM?

Well, it's been a little over 48 hours now since I moved from 2.3.2 to 3.0.1 and I have to say I'm pleased with the battery life. It goes down to about 70% after a 16 hour day. And I have not even considered having to soft reset yet... still running off the original reset after flashing the phone.
I think we have a winner here.

Reg Tweaks & Advance Config 2.0
Sorry guys,
I dont know why, but when I loaded up Advance Config 2.0 somehow it showed those reg settings (power management) as enables? I should have checked with my Registry editor. Either way, my phone battery life is back to normal.
Great job DCD!

I am having the same battery problems. One thing I'm wondering if it's how it's reporting the battery level that's the problem because my phone indicates that it fully charges abnormally fast as well as drains fast.
running dcd 3.0.0. I guess I'll try a hard-reset as others suggested.

I went with Keys' kitchen that's based of 6.0 and Sprint's latest release and my battery seems to be much better now. I don't know if it's the way it's being reported with the incremental dll or something in 6.1 that's doing it but i'm not down to 70% after 2 hours of doing nothing with the phone now.

After some playing around I believe it to be the GPS. If I turn the GPS on, I can practically watch the power bar tick down. If I exit google maps, it still seems to keep sliding down the scale.
However, if I reset my phone (not just exit the program) after using google maps, and go back to normal use without using any programs to initalize the GPS, the battery life is what I was used to.
If anyone else is seeing this, try going a day without even activating the gps, and see if you can notice a difference.

A thought on the GPS and battery life:
I have not seen any of the issues related by others with the GPS. However, I am using a nav program called Odyssey Mobile (it came with my Holux GPSlim 236 BT unit that I originally bought for my 6700). With this program, it starts the GPS just like it should with no reason to jump start it, and shuts it down when I exit the program. (Plus, it allows me to keep my maps on the microSD card... I do not want to have to rely on a data connection to get maps a la Google Maps or MS Live Search).
Not a plug for Odyssey, but instead more an observation that maybe progs like Google Maps are not shutting the GPS down like they should when exited. Odyssey has an actual "exit program" button instead of relying on the "X" to close it in the normal WM style (actually you can't even see the WM6 interface at all when Odyssey is running) and using the exit function completely closes it. I suspect that maybe Google Maps isn't really closing for you guys and that's why a soft reset fixes your GPS.
Again, just a thought.
I'm closing in on 72 hours since I installed DCD 3.0.1 and still only going down to 70% battery by the end of the day... plus I STILL have not had to soft reset (it's becoming an obsession to see how long I can go without resetting!) and the phone is still as snappy as it was immediately following the flash. Not one single problem... the 3.35 radio/3.0.1 ROM is easily the most stable combination I have used. No ifs, ands, or buts.

batterry life
Hi guys,
i posted the same issue under this same section but different thread about my battery not lasting more than 12-15 hours after jumping to DCD 3.0.1 whereas with Sprint official (using the same programs and usage) i will usually get 35+ hours, even two full days depending of usage. so guest what i changed the power battery tweaks:
Battery Improvement Registry Tweaks
HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms
Default value type and value are
DisablePowerManagement�=dword:0
Change to
DisablePowerManagement�=dword:1
HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms

HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms

Change to
DisablePowerManagement�=dword:1
HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms
Default value type and value are
DisablePowerManagement�=dword:0
Change to
DisablePowerManagement�=dword:1
using DCDs because i'm assuming that when i'm using sprint official (on which i get more batterry life) i don't have these tweaks and my phone went from 74% to 73% in a period of 2 hours and 42 minutes. be my guest and explain whats going on. lol
just wanted to post this.
NOTE: after i changed everything from 0 to 1 on DCDs, baterry was draining like crazy i soft reset and woila!! solved.

Battery Life? Nothing running, no calls, or messages. 10% down in an hour?

Is this what everyone else is getting? I am running DCD's latest Rom and Radio.
I used to get two days, now i may get one. This is with no GPS running or any programs. Or making any calls.
Any advice?
Rephrase then.
How much battery life is everyone getting on the new Rom?
Are you sure your wi-fi switch is OFF?

"These are some factors that could cause your battery to drain fast"
The brightness of the screen is a factor. Try lowering it if possible.
Disable active sync, bluetooth, wifi, and beam when not needed.
Using the GPS drains the battery quick. ( results vary )
Push email also assists with battery drain.
Put your phone on standby when not in use.
Also the extensive use of PIE and Windows Media Player also assists with the drain of battery.
Last if you have poor signal strength this can also be a factor for battery drainage.
There are others out there but these are some that I encountered and learned live with.
There is a battery hack out there that can help you with your battery life. I don't know from the top of my head but search for a registry battery hack.

all those are try but when you first got your phone did you charge it all the way before using it cuz messes up the battery i know it did for me
Follow up.
On my original Rom I could get 48 hours on a charge.
Today I got 8 hours. I did not use GPS, I am not using vibrate for calls. I only got two calls. And two emails.
Basically I am using the same settings as I had on the original Rom and getting about 24 hours less battery life.
I guess I'll switch back and report then.
Perhaps this might be it?

DAMN.. that would explain alot.. I have a feeling its the same bug with the titans..
I dunno... I've been through the progression from 2.0.0 to 2.1.0 to 2.2.0 to 2.3.2 and I haven't seen anything like this.
I use the phone for about 10 minutes a day, so not much call time, but I have it checking 4 IMAP accounts every 15 minutes, do about an hour of web browsing, and use the GPS two to three times a day (basically any time I drive anywhere cuz it's fun!) and the most my battery has drained is down to 70% after about 16 hours.
Just to give an alternate view... battery life has been very good for me.

No. When I first got my phone I installed on the apps I researched before buying the phone, configured my WiFi, and imported my playlists from Windows Media and then I charged my phone with the AC adapter.
I use alot of WiFi through out the day along with Stereo Bluetooth Headphones to listen to music one Windows Media Player and I have a very good battery life.
Follow up.
My email server locked up this morning and my activesync wouldn't sync.
BUT my battery life was back to it's old self, used 6% in 4 hours. Very Happy!
Email server is now working and Active synce is syncing.
When I check the activesync program it always says connected now. Is that normal? It doesn't seem like it used to say connected all of the time.
It does look like activesynce may be the problem. The setting are the same as they were before the flash.
Any info would be appreciated.
Update: In case anybody is following this.
I went back to stock ROM and Radio.
Battery behavior is back to Normal. I am going to reflash to GPS Rom and see if that was the problem.

I an confirm this too. A few days ago I noticed excessive battery drain and reset my phone, and put it out of my mind. The only later ROM that I'd retained for days at a time has been 2.3.1 and today my battery level feel down by 50% in ~6 hours of standby. With the power on, with 46% remaining, the OS estimation for usage was 26 minutes. In 1% increments I could see it counting down....
I checked all running processes and nothing was out of the ordinary and nothing except that running task manager was bothering the CPU.
On a reset it appears fine.. Disconcerting. My phone didn't demonstrate this behaviour with the DCD 2.1 and previous ROMs. I don't know if to go back to 2.1 or 1.6.10. I'll see if this issue shows up again over the next few days.
That was the same problem I had.
Hopefully I'll dp some more testing this weekend.
After a reset the draining was repeating for me.. I decided to revert back to a working DCD 2.1 set-up and all appears fine again.
2.3.1 ROM was a kitchen build including the transcriber and no2chem's nueLED v1.5. That's all that I can think of being out of the ordinary.
I thought I am the only way with this problem. I thought it just a bad battery. Using DCD 2.31. Before 2.31, battery is about 90% on casual used when I left work. With 2.31, it becomes 95% after it pull from the power plug. Browser the web for like 10 minutes, it goes down to like 92%. By the time I finished work, and get back home around 7, it left with like 30%. That's on casual use.
Anyone tried reflashing to see if that helps the battery consumption?
It seems like this is not common, but effects a few of us.

I am also noticing the same effects, i was thinking bout reflashing my rom, i am currently running dcd's 2.3.2
Flashed back to stock and then back to 2.3.2
It looks like I am seeing the same battery drain again!! ARGH!!!
My battery is dropping like crazy too since the latest kitchen. When I first went to DCD's first WM 6.1 ROM I was blown away by the battery life. Same settings , same apps, different ROM and the battery life blows.
I decided to wait it out for a week and see if the new ROM comes out, if not I'm going back to the WM6.1 ROM that I first tried.

Battery on Touch Pro - HELP!

I am having a terrible time with the battery on my new Touch Pro. My battery goes dead in about 2 hours and unless I turn it off completely, I cant seem to get it to charge.
I finally ran the NuePower driver to see what my power drain is vs. my charging ability. I have attached a screen shot.
The phone can charge at 439 mA while connected to my laptop. The drain is at 523 mA when the internet is active.
When the internet is not active, the drain drops to 220mA which is enough to charge the phone.
I have verified that WIFI isn't turned on. I have also turned off Bluetooth and it doesn't seem to have an impact.
I had a mogul for years and used it in this way and never had battery problems. The phone would easily last all day.
Has anyone else seen this and if so, do you have any suggestions?
The only thing that really drains my power on my HTC Pro is ActiveSync. A quick fix is to use the Adavanced configuration tool and change the power consumption options to your liking. Also I heard changing to a new theme or Rom helps the battery last considerably longer
I had the same problem with my brand new TP. the battery only lasted 4 hours on standby,and used to get really hot. I only had it for a couple of days then I took it back to the store, and got a new one. The new one is a lot better and doesn't get as hot.

A new battery or a new phone?
took about a week for my battery to get "broken in" and at that point i was going about14-18 hours with TF3D running. I am now using Spbmobile shell 2 (really just waiting for SPB MS3) and i can go nearly 2 days now with just texting, a few calls, and checking email and internet a few times. It will last for a full 24 hours with heavy use as well.
When I first got my Sprint TP I only got about 7 to 8 hours of battery. What I did was to disable Rev A on the phone. Now I get about 24 to 30 hours
Well this is pretty common on just about every forum who discusses the TP....
My battery is much better now that I flashed the MightyROM...Apparently he has some power tweaks in there that actually work...
I also found a slightly bigger battery that fits inside the standard case on Ebay...
I now get through the day on a single charge provided I don't make a zillion calls all day...

Sorry, I am new to this forum and phone (1 week old). What exactly do you mean by "disabling Rev A?" I know from reading the threads that switching to a different ROM would help however since I am a newbie, I dont want to risk flashing my brand new phone and potentially messing it up. Thanks for any help!
Disabling Rev A on a Sprint Phone, will make it go back to EVDO rev 0. Is not as fast as Rev A but is a lot more stable and is better for the battery. To do this you have to get your msl code, I'm attaching the utility that I use to get my code. Just install it to your device memory. when you run it tap "get spc/msl, tap yes to the warning and write down the number that it will provide for you, that's your phone msl. Now tap on Launch EPST and hit edit, enter your code, on view info go to "Data Parameters" and there you will see Rev.A, disable it and hit menu and Ok, reset your device and ready.
You may need Net Framework 3.5 for this app to work properly
I did not wrote this app nor I take credit for it.

Thanks alot for your help! I actually used a cab that I found here or on PCC that has worked great for the first day. I pretty much went the whole day without charging which hasnt happened since I got the phone last week. However, after forgetting to unplug the charger to my phone last night, I woke up to an unresponsive phone. I know I have read that problem with other people. So I just wont charge it overnight. Well back to the battery, this cab seems to work quite fine so far. Here it is in case other people want to give it a try and maybe let other people know about your experiences.
hi I used to have this problem too. at least until 2 days a go. my battery only last for 10 hours. That was the best my battery can reach. then i find that htc.com release a new update rom. i upgrade my rom then as suggested by some forum i discharge my battery till my TP turned off it self
They says to ensure that TP cannot boot up again when we press the power button. The sign is a red text saying "battery is too low..... bla bla bla".
Then discard the SIM card (if any), Then charge the phone at least 8 hours (12 hours for best result). You SHOULD NOT turned on the phone while charging.
The result :
I do this step at march 18 2009, 10 Pm. Finished charging with 100% battery reading at 10 Am (march 19). After using it for about 2.5 hours calling, about 45 minutes GPS (Garmin Mobile XT), i still have 41% battery today (march, 20 2009 : 5 PM)
A good improvement for my TP. I will report the next days result.
May be some one would try this as well? hope my report could help.
Ps: im not sure that new rom is one of the factors causing this battery live improvement. so you may try this without updating rom
I posted this on another forum. Seems that some of these are shipping with defective batteries. Same thing happened to me earlier this week. Battery would only hold a charge 10-12 hours and I wasnt using it much at all. Took it back and got a whole new TP, this one's battery has been working just fine and I leave Bluetooth enabled and everything.
If you are having issues with the battery dying 8-12 hours in and you arent really using it, take it back and get a new one.

I had issues with this when I got my Touch Pro. I had to charge it about 3-4 times a day. Now, I charge it 1-2 a day. This is how I managed to achieve that.
First, I bought a Seidio 1500mAh battery on ebay. This gave me a little extra juice. And no need for a bulky back cover. http://cgi.ebay.com/Seidio-1500-Bat...wItemQQptZPDA_Accessories?hash=item35a3e9b967
Then, I used Codybear's ASKicker to stop Active Sync from running in the background...it eats up juice. http://forum.ppcgeeks.com/showthread.php?t=72242
miriror: http://rapidshare.com/files/268159114/SHKCustoms_-_ASKicker_Beta1.cab
Con: you won't be able to activesync- this app prevents it from starting up.
Now comes a super program that made a huge difference, Nuerom's DynamicClock http://www.nuerom.com/BlogEngine/page/nueDynamicClock.aspx This useful app slows your clockspeed down so it won't utilized alot of your battery. You can also keep it at max speed-but watch your battery drained faster.
For example: I have the app activated it now and it reads: [email protected] (with backlight on 245/[email protected])-now set at default:[email protected] the voltage...depending on how much apps you are running and installed- you might not noticed the sluggish.
Con: Some of your apps may require higher speed, so you might have to change the speed back- but it is all of matter of just making a quick change.
I also recommend G-light. Get it here: http://www.freewarepocketpc.net/ppc-download-g-light.html This useful app, adjust the backlight based on the environment. I don't have to ever adjust the background manually. This saves the battery by lowering the backlight.
All these apps (and batter) have made a HUGE difference. When I did a hard reset, i noticed that the battery went from 100% to 50% in about 1hour with minor use. After installing the apps in- it went from 100% to 80%...again it will vary depending on your apps you have installed.
Hope this helps.

Need Help With GSB v2.4

Hello everyone! I would have posted this in the actual GSB thread but I don't seem to have the correct privileges yet so I am posting here instead.
First off, I just want to thank workshed for his awesome work. I really do love the ROM and everything about it. However, I have a few small issues with it that I can't seem to figure out.
First off, my battery life is terrible. Take yesterday for example. I used my phone probably twice to send some texts in the morning and to check the time. Charged it throughout the night and pulled it off the charger when I woke up and began my day. Within two hours, my phones battery was down to 75%. Five hours later, it was completely dead and I hadn't even used it.
My second issue is with settings. For some reason, when I reboot, some of my setting don't get saved. The one thing that really bothers me is the keyboard. I have Swype installed and every time the phone shuts off, I have to go into settings and re-enable Swype as my keyboard. It is just a hassle and is kind of frustrating, especially when I forget to do and then go to send a message.
Other than those two issues, I absolutely love the ROM and wouldn't change it for anything else. Anyone have any suggestions for what I can do about my few issues?

Recharge it until you get a green light. Restart the phone in Recovery, go to the Wipe menu, and wipe the battery stats (I'd keep the phone on power for this.) Restart the phone, pull the power and use as you normally would. Ignore anybody who tells you that you must run the battery down until the phone shuts itself off - this is really not great for the battery (though once a month or so isn't bad), and really isn't necessary for the battery calculations to reset themselves with new usage stats. The longer you can go the better, but it's not necessary to change your phone usage habits so that you have a completely discharged phone.

Thank you for that information, I shall try it out and see if it helps!
I also forget to mention one more error. Whenever I boot up the phone, my Facebook account sets itself to not sync and I lose all my contact pictures. I then have to open the Facebook application and set it to sync again.
EDIT:
Sorry, didn't realize it was a double post!
My battery life is similar to the OP's. I can make it through the day, but since I am ususally down to about 60% by one or two pm (from 6 or 7 am) I prefer a mid-day charge just to make sure I can last through the evening.
I just flashed [ROM][3/22/2011] GSB v2.2 | GingerBread 2.3.3 [CM7.0.0 RC2 NIGHTLY] a few days ago and it has been running great, but I noticed that my green light (battery fully charged) now comes on @ 90%.
Before it would not turn from amber to green till 100%. Should I wipe battery stats?
Under battery use (sry no screenies) there is nothing unusual:
Display @57%, everything else under 10%.
But when I checked Spare Parts I noticed that my little Eris won't sleep!
It looks like Android system is the culprit, keeping a partial wake lock.
Battery History in Spare Parts:
Other Usage - Since last unplugged
Running 100%
Screen on 13.2%
Wifi on 100%

The phone has more or less been sitting at my desk at work in wifi with light usage.
Anyone have any idea why Android System is trying to eat my battery?
i had battery problems on gsb its a great rom. i switch to ginger tazz. with tazz's rom i get more then 20hrs b4 it says to connect charger thats with the display on about 4 hours and wifi on and running facebook tapatalk calls texts and whatever i think of doing.
I'm running GSB 2.5 CM RC 4 and I now have been able to get 25 hours with 70% of battery left. I used to be able to get maybe 24 hours before it died. Now your mileage may vary but this is what I do. I removed Task Killer which was eating a bunch or the battery and after a visit to Amazon's app market their little app was running all the time along with Weather Bug so both of them are now gone. and finally I turned off auto sync ( I can check my email when ever I want and it takes a lot less battery). By turning off auto sync that was what really made the difference for me. Of course there are many things you can do but running WiFi will kill your battery faster than 3g (or at least it does on mine) and I have the screen brightness set at 18. Just a note I leave BT and GPS on all the time when they are not being used an are in standby their usage is quit small.
What works for you would depend on if you want your email pushed to you all the time and if you have to have your WiFi on instead of 3g.
Again it's just my observations for my phone.
Really you should just do the first suggestion and recalibrate your battery.
Also if you read closely in workshed's log, he specifically said to a full wipe not only formatting external memory but also doing a dalvik/cache wipe. You may as well also wipe the battery stats while you're at it.
Personally I'm running GSB 2.5 and it's simply amazing. 60% of the battery gets me from wake-up alarm to nighttime charge.
Hope you figure it out!
After I installed GSB 2.5, my battery also seems to be rapidly discharging. Takes less than an hour of no use, wifi-on to drop from 100% to ~80%. I did a full discharge calibration on my battery as soon as I flashed to this GSB 2.5
I will attempt the simple batt stat wipe at 100% and see if that helps at all. I'll let you guys know.

Another(Really WORKING) battery life hack - temp fix bug in all ROMs

After a lot of playing with T-Mobile US HD2 WP7 i found one interesting thing:
If i start camera with green button and then switch to video mode there, wait for autofocus and after that just simple go out to main screen by pressing windows(middle) or back button then standby Battery Current drops to -5-6 ma from regular -40-42 ma(minus means discharge). (Switching to video is important - if not switched no results found)
It stays -5-6 ma on standby until next reboot. If i reboot and don't do this camera play current is -40-42 ma. But if i start camera -> switch to video -> out - Battery Current -5-6 ma. To measure use Battery Tool.
After hack/trick applied I used phone in different ways - talk internet email - standby still low 5-6 ma. I gave it 12 hours try - lost only about 12-13 % of charge. Checked battery outside of phone with load - real lose of charge was about same as Battery tool shows. Will continue to test longer but can expect at least few days with some usage of phone. Did the same trick with my friend's phone - same results. It looks like really a bug some where.
This problem really exist and found in all ROMs.(a little difference between TMOUS and EU HD2)

FOR this trick to work on any ROM versions(including all Mangos) software WP7 radio must be lower then 5.62, so only from 5.51 to 5.61 works. Recommend to use 5.51 or 5.51T soft radio and trick will work all the time.
History Update:
As of Apr 29, 2011: Confirmed to work for most people. This has to be done ONCE ONLY if you reboot phone.
Confirmed one phone has low standby current 3-7 ma after reboot without this hack - but model of phone is ORIGINAL HD2, not T-Mobile US. ROM is HD2O 1.04.
One T-mobile US shows low standby at bootup. XBmod 1.04.
If your phone shows 3-9 ma standby after reboot without this trick - then this not for you. Your phone has good standby already.
Real battery life vary from about 4 hours(continues usage of cell data and browsing) to 4-5 full days (standby only no usage at all-just few short calls, location on, data on, bluetooth on, xbox off, wifi off).

Update:
Tested HD2O 1.12 nodo - trick works perfectly right away getting 3-5ma!!! After a day of use(not much use) - battery life is amazing!!!
Tested original NODO(YukiXDA) one more time(total two times flashed this rom to be sure) - couldn't get stable low standby - unpredictable, most of the time 40-42ma sometimes even higher. Tried so many times. I don't know why results are not so good. Update: Yuki original ROM used different WP7 Radio - 5.66 - which is not working with trick on TMOUS HD2. For trick to work TMOUS must have 5.51 or 5.51T Radio.

Tested XBmod 1.10 nodo - trick works perfectly right away getting 3-5ma!!!

Continue using of HD2O 1.12 - battery life is amazing!!!(T-Mobile US HD2) Didn't have any single stability problem for 2 weeks!!! Speaker volume can be adjusted with registry hack.

Update: Yuki original ROM used different WP7 Radio - 5.66 - which is not working with trick on Eu and TMOUS HD2. For trick to work for 100% in 2G and 3G, ALL HD2 must have 5.51(original DFT) or 5.51T(from Ansar) Radio(part00.bin).
From my experiments 5.51T looks a little better than 5.51 overall(not sure 100%). There is no any benefit for me of use 5.66 Radio. Just use any WP7 ROM(even Yuki's ones) and replace part00.bin for trick to work. It was TESTED on all Yuki's ROMs.
Jun 08
Yuki's v3 final works exactly the same for standby current - radio 5.66 in ROM trick doesn't work, if replaced with 5.51T - trick works as usual 3-9 ma in all modes
Jun 09
Tested HD20 1.14. Much better than Yuki's for me(TMOUS) - more stable, feels solid no stability problems at all. For the first time HD2O changed Radio to 5.66, so i had to change part00.bin back with 5.51T to have good standby - 3-7 ma in any mode 2G or 3G with the trick. HD2O 1.14 is the best ROM overall again! Overall best and battery life is amazing after radio changing!!!

YukiXDa made the best ROM now with V4 lang2. I have never had so good battery life before!!! I have used 5.51T(TMOUS) with trick.
Excellent work Yuki!!!
Jun 29
Yuki made even better - V5. I am able now to get to some registry enrties i need!!! Enerything is perfect for me, except too many shortcuts to all setup settings.
Hello
Yes you are right.I´ve tried it out like same way and in that second i noticed that my Proximity sensor turn on.
I mean ive set my backlight to auto,but no proximity funktion.But when i turn on my camera bla bla then the proximity sensor turns on to function and my Backlight turns brightness automaticly,like ive set it before.
Thanks for sharing this info bro.
where are u seeing if the drain is 5-6 ma or 40-42 ma?
In Battery tool - Battery Current. Start Battery tool leave it on screen send phone to sleep. Wait a 2-3 minutes or so then wake it up slide to unlock and wait 10 sec with tool on screen - it will show current when it was on sleep/standby. if you were quick enough. Do it several times you will see it. I did this tests periodicaly last month with different roms - aprox same 40-43 ma with radio and data on(radio off gives 2-3 ma and phone lives forever). I have verified battery tool is correct or not by connecting once real multimeter between battery and phone. tool is correct. If divide 1230ma(battery) by 40-43 can get at best 30 hours of standby.
May be need to wait more than 2 minutes to get real sleep/standby - it depends on previous state. After few tries you will see. Stable average of lowest figures after few tries is your standby current.
intresting....just testing now........
well bugger me sideways, it works! nice one mate
Interesting finding man! But i wished i had my HD2... Still a weird bug but promising..lol
Where can I find the battery Tool? It's not in the market.
Sent from my HD7 T9292 using XDA Windows Phone 7 App
Here you can find. It is XAP and need side loading

Dont know for sure what it does.. but semms to solve my problem testing since 6 hrs.. still gonna test it for some more time .. lets see..
Looks like when camera closes from video mode it stops one or more of the running in background process which take some drain all the time. Probably that process should not be running at the begining. Develovers like DFT or Cotulla may be should look at it closer. Big thanks to them for hard work.
I feel like this may be finally the solution to our battery drain issue. Since I noticed that at first, when I install new rom to my HD2 the battery life is fine, but when I take a first picture with camera (or simply restart the device aswell) the battery starts draining itself. But maybe that's just me, anyways I'm gonna try this and if it works I will report back,thanks to the OP
Running already 2 full days with data on, bluetooth on, location on. Still have 30% left - real 30% verified battery out of phone. Used internet, mail, talk - all of them not too much - normal way as i need. Before this trick phone couldn't survive 24 hours.
Forgot to tell checking all the time Battery and current status take enought energy too.
Damn! This just hasn't worked for me! I'll try again, but after trying this trick my battery seemed to drain faster
I normally have it charged when I get up in the morning & have to do another full charge 2/3 of the day through. After trying this trick I had to do 2 full charges yesterday!!!
I'm going to try again as I said, but this could be due to the reg hack that doesn't kill apps, I applied.
I want to add to this post about my experience with Battery tool. It is accurate at least with ROM i have. Charge level, current and voltage. And WP7 charges battery to full. plus minus 5-10 percent(this low margin doesn't make any sence). I have verified it by discharging battery out of phone with known current. Did several times. So battery was charged to good approx 1200 ma in phone to green light in WP7. As i said at least with ROM i am using. Didn't try this with others.
That doesn't work for me neither, it drtains the battery faster than usual....perhaps it is my rom....
Try to measure stanby current as explained above. It shouldn't do anything worse - you just start and stop video camera. Unless really something wrong with ROM.
Strange, it seems to be working fine today! Thanks for the tip! I didn't do anything different, but it's working!
Hell yeah! It actually works, now I'm getting 2-4 mAh, instead of the regular 40-60. For everyone who says it doesn't, try to do the trick, put your phone to sleep, wait for like 10 minutes, wake it up and start Battery Tool again, it should show much better values then. Thanks again. Spread the word!
This definatley works for me ..brilliant find thanks
thank you very much - work for me. after all the battery threads that sounds good but have no effect for my phone.
thank you!

[Q] ED01 Battery Issues

My wife is fully stock and I'm on the Ultimate KangBang Rom. Both have the ED01 Radio's and no 3G issues that we are aware of.
Since the update, we are both getting far worse battery life.
I have not touched the voltage controls in the rom.
Anyone have any ideas?
Could this be related to a 3G issue we simply are not seeing?
Should I (as she is not rooted) try to reset the battery stats after next full charge?
Should I call 228 to make sure everything is kosher on that end?
***************
Update:
I unplugged this morning at 7:30ish. 100% battery.
I started this thread at 10:30ish. 75% battery.
~3hrs, light use, lost 25%.
I hit both options in *228 at 10:30ish.
Its now 1:30ish. 71% battery.
~3hrs, light use, lost 4%.
I think the update, in general, just screws up your 3G/roaming etc. This was already known with other issues Verizon had over the last week or so. This seems, to me, as the most likely cause of battery drain.
I'll will come back later to say if anything changes. Also, need to see if wife ran the *228 options on her phone and will report back if findings are similar.
Hey superchunk,
I have a somewhat related post in the general section, and am finding low cell signal together with Google location services are giving me 4-8% batt loss per hr. See below. Also make sure to toggle airplane mode once per boot to workaround the 50% TWOS bug.

Check what apps you have installed. After I did the full update to ED01, and then replaced the kernel with Imnuts' -100 undervolted kernel, I was getting great battery life until I installed the full Skype client. Even logging out so the program would quit, the battery started draining upwards of 10% per hour, even when the phone wasn't being used.
It seems Android in general, and 2.2 specifically, is pretty vulnerable to errant battery drains. Worst part is that it didn't stop after I uninstalled Skype, so I had to go through the whole process again - back to DL09 and then update.
We've always had google services on (before and after upgrade), so I don't think that has anything to do with it.
Neither of use have Skype and no other apps have been installed anything new (don't use skype), but that doesn't mean something old has a new undesirable effect.
So far, I've ran the *228 options and will see if that helps. I'm thinking we simply haven't noticed 3G dropping and really needed the updates to programming and roaming.
Having a phone constantly searching for its best band will cause quicker than normal dead batteries. This is one of the reasons the Thunderbolt is getting so many negative marks for battery life, LTE just isn't there yet.

Seems the Google location services battery drain was much less of an issue with 2.1.

Have you charged to full and wiped bstats?
