HI GUYS
IM USING RADIO 2.15.10
AND HSPL 2.08 ,
MY BATERY DRAIN VERY QUICKLY , I HAVE ALL SETTINGS OFF , 3G OFF. WHAT I DO WRONG or what i need to to to corrrect this issue.?
anyone are having the same prob??
tnks to all
there are at least 2 threads on the first page about this...
check the first post here http://forum.xda-developers.com/showthread.php?t=1041912
i read in one of the threads that we should charge the battery in magldr usb mass-storage mode for about 6 hours, and that worked brilliantly for me...
gave me about 40 hours of battery...! (3g on / data/wifi off - data/wifi on when needed)
i try use that mode but the charger light dont show ON , is not charging , i try using the charger directly to ac power and cable directly to pc mode but nothing he didnt charge .
Radio 2.15 seem to drain battery too much (from my own experience).
You can try old radio and see if battery life is getting any better (I recommend 2.12 & 2.14)
omg my phone only hold on 11h today with low usage, i dont know how to make him stay more time alive , the raDIO 2.15 I DONT THINK is the problem because many users are using 2.15 and dont say any... any sugestion??? if i cant fix the prob i need go back to andoroid or 6.5 version

Try to use HD20 1.12 and do video trick - with low(if it's realy low) usage it will easely survive 2-3 days.
i confirmed last night that the charge trick in magldr in usb storage does work to charge the battery.
I found that when my phone starts to get lower on battery that a reboot gives me more power due to the power meter being out.
Also a charge in an external charger helps.
sorry im trying to understand how can users see the MA off batery in battry tools , im trying to use the trick of change the camera mode to video mod and leave , they say the batery consume go to very low usage , like they say here but i cant find the "MA" in battery tools to compare .
this is what they say to do
"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 stanby current drops to 5-6 ma from regular 40-42 ma. (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 - current 5-6 ma.
After hack 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.
Please report your results and HD2 type.
Was on XBmod 1.04, 12 radio, location on, data on, bluetooth on, xbox off, wifi off.
If this problem really exist it will be found in all ROMs.
P.S. Tested phone before with most others ROMs - found this one is the best, thanks for this ROM.
Hope this will be fixed permanently in NODO."

Yes you are right it is not show ma. Electrical current is measured in Ampers or MiliAmpers. So look for Battery Current minus when on battery, nothing(plus) when on charge. Do video trick send phone to sleep mait few minutes, then wake up and fast go to battery tool wait there - you will see. Most important is ROM type. They should be all same, but a lot of testing shows they are not the same(not big difference, but exist in standby consumption).
Want to add - if used proper ROM and this trick you won't need any external charger, because i doesn't give much(internaly battery charged very well - i did a lot of external experiments with battery charged in phone), no need to go any magldr because not help much and dengerous for battery. if you use pfone a lot you may need only charged(in or out) spare battery because it works continiously only 3-5 hours.

I'll try to play with camera modules this WE since they seems the same between HD2 and HD7. But like I've said the bug is certainly due to the flash driver or a dependency with the camera driver or pdd/mdd.
For the rest (Wi-Fi apart) there is a lot of differencies between users with the same rom. Tmous/HD2, revision number of the device, OP/ coutry (for gsm band) etc. all this count to what radio we use (HD2 and HD7 extracted) and some drivers may be not acurated.
The RIL parameters for your OP are important too beside the radio because how your phone reach the GSM network has an important impact on battery consumption.
There is a tool I dindn't know exist before and testing now which I like: WP BENCH.

Yes you are absolutly right - a lot of unknown things and differencies. It would be very good if you will be able to look closer at all this. I don't have tool, enough knowledge and actualy much time to do that. Thank you very much for your work and results!!!!!
Yes, it's true. It worked with the camera bug... Normally my battery would be empty. But now I only used a quarter of my battery life. Nice !!

i would like to turn off devices on my TG01 off to save power:
i use my TG01 just as a pocket pc, i.e. i have no sim card inserted. nevertheless, battery is down at 40% after 1 day of standby, even when in flight mode.
as i heard that flight mode does not really work on the TG01, i would like to selectively turn off devices like phone (gsm, 3g), wlan, bluetooth, motion sensor (all the things i don't need), while keeping the gps still working.
is there a rom version or a tool that allows me to really turn off devices separately?
or is there a rom version, specially made for people just using the TG01 as a ppc?
so far, i always have to keep bluetooth running, as the gps does not seem to work as soon as i turn bluetooth off (no idea why it is like that). maybe it's bluetooth that drains so much power...
i actually run the wm6.5.5 v5 rom from novembre5
or is there anything else i can do to save power?
btw:
i tried to measure the current, the device draws from the battery, to find a setting that is the most power saving. unfortunately, all battery meter tools i tried are not able to show actual current. is there a tool that supports the TG01?
please help!
Some tips...

Use wireless manager to turn off/on phone, bluetooth and/or wi-fi separately.
In settings/motion sensor settings disable autoscreen orientation, in settings/sleep mode indicator tick off, in settings/power saving settings un-tick automatic brightness and choose a brightness level according to your needs and so on...
Does not really help!
...and with all those things disabled, the battery is down at about 40% after 1 day in stand-by (when the TG01 has not been used for 1 day)!
so i think there's still something drawing a lot of power!
to compare:
my hp ipaq 214 ppc, running wm6 too, is down at 40% after being in stand-by for 2 weeks, i.e. it's power consumption within 2 weeks is about the same as the TG01's power consumption within 1 day, when in stand-by...and the ipaq is much older than the TG01!
so it seem's obvious that the TG01 just tells to have everything turned off, while still having things running...
Very interesting...
Why don't you keep this thread opened in TG01 General , for instance? I'm afraid that your question it's not related with ROM development...(wrong subforum)
Best Regards
i thought there might eventually be a rom version with the PHONE FUNCTIONALTY DISABLED, or with tighter hardware/power control!
or maybe, there is a rom version OPTIMIZED FOR LOW-POWER!
that's why i placed the thread here.
if there is no way to get help in the rom section, this thread can be moved to general, but i have no idea how to do this.
thanx!

I am also enjoyed my TG01 without a sim card and then be surprised that it holds several days without being charged. So if your battery falls on a day not to use it, then the battery has a reduced capacity. Try several cycles - full charge, use it while off and only then put it to charge. Maybe this will help you.
hm 'holds several days without being charged' sounds good
so how are your settings for bluetooth, wlan and phone?
btw: i bought another battery because i first thought that it is a battery problem - but now it's the same with both of them.
i also turned the phone on once (but without a sim card), and it looked like the battery discharge was about the same as in flight mode.
i read somewhere, that because of a bug, the TG01 turns power of the phone chip on, when the device is set to flight mode, and therefore bluetoot or wlan has to be turned on to really turn off the phone (and save power).
on the other hand, i would like to use the gps, but the gps does not work when the unit is configured to flight mode.
so what is the ideal configuration for reducing power consumption?
thanx!

I believe you don't need a 1ghz processor device if you compare it with a 624mhz.
For tg01 you can even limit cpu speed for better power consumption in power saving settings...
i think when in stand-by, the TG01 cpu does not clock at 1ghz.
i compare stand-by power consumption, i.e. the cpu has almost nothing to do then.

DISCLAIMER - I am just putting this in here so that if anyone gets any funny ideas ... Whatever you read/use in this How-TO Post is at your own RISK. The aim of this post is to help others who had the same issues as me when they were abroad ... and were stuck without a mobile Running MGLDR 1.13 and DFT stock ROM (WP7) and a USB cable but no other chargers ... If the OS doesn't boot you WON'T manage to charge via USB UNLESS you follow this HOW TO GUIDE (it's the ONLY ALTERNATIVE YOU HAVE OTHER THAN BUYING A CRADLE CHARGER) ... it WORKS 100% but I am fed up of finnicky people emailing /posting / trying to play the "experts" on the matter when they know nothing about the matter
Dear all
After going through all sorts of Registry fixes which were momentary in nature. I decided to find a viable alternative which does in actual fact work with all current WP7 builds and all MGLDR's provided with a USB Storage option.
It has been said that the WP7 Software does not charge the battery to its full potential. I also incidentally ran into the problem of charging the mobile when the battery died. Primarily because the mobile loads ... restarts ... loads ... restarts and you keep on "praying" until the OS boots to get it charged.
Alternative fixes so far which worked for me were:
- Adding android to your SD Card ..booting in android and charging it in android mode
- Charging it in Cradle Charger
- Some people even pulled out 2 wires from a USB cable (+ve and -ve) to get their phone on again (crazy and dangerious)
- MGLDR 1.12 hangs when trying to charge mobile while it is off.
- MGLDR 1.13 reboots (as a momentary fix) in order to avoid the hanging caused in 1.12
Problem is
- I can't stand the fact that we have to have 2 OS'es to get it charged properly
- I can't stand the fact the we have to remove the battery in order to get it charged externally via cradle charger
So we have to adapt to the present circumstances unfortunately. If nothing, and the fix does not give you more battery life, this method avoids you from
- buying/carrying a cradle charger with you when abroad.
- having a dual boot system (WP7 / Android) on your phone
- making you do crazy/quick fixes such as the USB cable thingy mentioned above ... (don't try it)
no need for anything of that!
HOW TO:
So in a nutshell if you drained your battery too much and don't have a cradle charger ... with the added bonus that you may get improved battery life out of WP7 is the following.
- Boot into MGLDR setup menu (hold the end call button at start up)
- Boot your mobile and hold the "End Call button" to go into the MGLDR setup screen.
- Choose USB Storage menu
- METHOD A - Let the mobile Charge for 6 hours (typically overnight would be ideal) (Note: It will not over-charge and it will not damage your battery.
OR
- METHOD B - Charge the mobile for 4 hours (to keep mobile on overnight) and charge the last hour in usb-mass storage mode. This has the added benefit that you do not get your screen on for a long time. This will not damage your battery and those of you who are worried about over-charge can go for this alternative and not take any risks.
- NOTE that you will NOT get the charging indicator ON in this mode. PRECISELY that's the whole point of charging in this mode, the battery will charge to its fullest as it is not under the influence of the WP7 software. It is like as if you put the battery in a cradle charger and charged it outside.
- When you wake up ... hit the back button to go to main menu and choose RESET option to reboot your mobile : ) and voila!
RESULTS:
- I got improved battery life charging the mobile in this MODE. I got 36 hrs + of battery life (normal usage) which is very good.
ADDED BENEFIT: QUICKFIX FOR DEAD BATTERY - NO CRADLE CHARGER - NO DUAL BOOT
- There seems to be mixed feelings about this as some of the readers have reported no discenable difference in battery performance. While I will not contradict these people, I got improved longevity from the HD2's battery. Clearly the OS is reporting the battery level badly. If NOTHING this method still serves as a quick fix
- if you drained your battery and cannot get your HD2 on again
AND
- You Do not own a cradle charger
- Registry did not work for me.
SETTINGS - WHICH IMPROVE BATTERY LIFE:
- You can optimise settings as follows in order to get my same results, again I hear many of you not wanting this as it turns of features from their PDA but as I said above, we have to adapt for the time being:
Settings are -
- ROM DFT Stock ROM original build (issued 13/01/2011)
- Radio 2.15
- Screen timeout 30 seconds
- Screen brightness set to auto
- Wifi turned off (on only when needed)
- Bluetooth turned off (on only when needed)
- Location turned off (on only when needed)
- Data Connection turned off (on only when needing to check mail)
- Email sync turned off (not every 30 mins)
- 3g turned ON - UPDATED - I got better battery life with 3G ON but this may change from country to country so I suggest that you have a go with 3G being ON or OFF and see which is better for you....)
IF YOU USE THIS POST - HIT THE THANKS BUTTON - IT's the LEAST you could do!

Hi Alcatrazx,
sounds logical I´ll give it a try and report later, thanks.

Thx
Thx Bro!
Will try it later too. I'll report.
One question though... Do you need to do this everytime you charge your phone, or just the first charge?
Sounds interesting, I will try and report

Sounds like you have to do everytime... If you reboot your WP7, the battery is under the influence of the software again and does not charge correctly. Beat me if I'm wrong
Very interesting. I will try it
It's a good idea for some times, but I would not use it as an every night thing.
I sometimes get calls or messages during the night (and usually they are important). Another thing is that if you use your phone to wake you up this will not work at all.
I hope WP7 development progresses and solves this issue in the upcoming updates.
Nevertheless it's a nice way of going by, and thanks for taking the time to test it and post about it.
PS: does the light turn green after 6hours of charging or not. Probably not, but worth asking .
Another solution should be to charge a second battery in an external charger...
pronor
Another issue with this "workaround" is that MAGLDR keeps the screen opened, which can cause some devices to overheat, so be cautious with this one. I say that an external charger is the smartest alternative. I actually use this method and it works perfectly.

Sorry to sound pessimistic, BUT, people have already reported clearly in other Threads that they have tried the solution of charging their battery using an external charger with no luck. I can't see how this is any different. In addition, 6 hours will probably kill your battery in the long run (overcharging) - I have queried HTC support about it in the past.
Simple enough mate! Though 6 hours of battery charging will probably make significant damage to your HD2 battery... HD2 normally will charge in about 1 and a half hour or 2 udner WM6.5 or Android!
Not bad idea though! Bravo..
Charging while in Android remains for me the most convenient option. I must say though that this battery issue in wp7 is not that obvious for me. The phone charges quite well in wp7 and only sometimes I feel the need for a restart, after which the percentage increases with 15, not more.
most chargers since the beginning of time have a battery cut off, when the charger unit detects the polarity is starting to reverse it switches off, of course i cant say for sure using the MAGLDR method would use this, potentially it could just be a case of "connecting two wires to a battery" which as you guys have pointed out would not been good, at worst your battery could get seriously hot, or potentially if you reverse the battery polarity enough you would have half of a battery thats unusable.
I think what should be taken from this however, is that like myself and other have been saying for a long time, if your battery is charged propperly it will last a long longer, people reporting empty batteries within 20 odd hours, in my opinion, either have dud batteries or are not charging them properly
the MAJOR plus side to this post is the ability to fix the empty battery restart issue, that alone makes this idea a gold star and should be stickied!

People reporting these batteries issues my friend are people who are knowledgable enough to reach to xda-developers forums - i.e. people who have a pretty good understanding of what battery drainage is and whether their batteries are dying or not; who have installed a number of winmo roms, android roms etc.
there are roms that drain battery and others that handle power better. in the ports of Windows Phone 7 for HTC HD2 there is an issue with battery drainage, and thats a fact.
There is no issue with bat drainage but with false bat stat reporting.

your level of wit and sarcasm is actually quite funny given that you completely got my point wrong, the issue is quite simply this, the drivers for our HD2 are copies from another device, a device that is similar but not the same, the issues we have with battery are down to the fact that WE do not know if the battery is charged or not, at least at a first glance, and given the inability of many people on here to actually read threads and posts correctly it is not beyond the realm of possibility that many users dont know what level there battery is charged to, thus it may not be charged propperly.
If windows reports a full battery and its only half full then it will "appear" to empty twice as quick, now i think thats pretty clear for every one?

we cant
our phone must be different to a degree than the phone this ROM is based off otherwise we wouldnt have the issue, lets all assume for a second we can actually start chopping and changing files in WP7 like WM. We would need to find some sort of driver that exactly matches our HD2 and i doubt that will happen.
whoever made the driver isnt going to just bring out a new version for an old peice of hardware that isnt supported by MS, perhaps if a new piece of hardware has the same battery controller as us something can be done.....maybe

You have the following options:
1. Try the registry tweak. That worked for me and I actually have no battery issues for the last 2 weeks or so.
2. Charge the battery under Android during the night. That's pretty usable as you only need to reboot and you still have a fully functional phone Way better IMO than the USB Mass Storage trick.
I have a minimal Android installation on my SD (Angry Birds, you know) and it currently reports roughly the same values as WP7.
So, I have had a serious battery drainage problem, like most of hd2 users with wp7.
My battery usualy run max. 24h!
Now my phone run 2-3 days without charging.
I have just turned off connection with xbox live
So, go to the settings -> applications -> games, and turn off "Connect to Xbox Live"
I have 3G off
Data connection on (but mailbox, shares, weather ect. is updated manualy)
I hope this will help you...
Interesting will give it a go..... I have to say I beleive this and other 'solutions' may be solving part of the sympton and not the root cause BUT if it helps that's always good news until the chefs can get to the bottom of it!!
Thanks will let you know.
Cool cool
I already did this now.
Will also check it, and provide feedback.
Battery life is a bit of a problem, but atleast i have a car charger
I will give it a try.
3G on
Data connection on
its work this solution ?
I think it should work. I checked battery dainage with Xbox on right after turning phone on after sleep - about - 42 mA. So without use of the phone max time is less than 30 hours. But if Xbox is OFF current is just 5-7 mA. Means 6 times less on stanby!!! Will give it real timing try. Used Battery tool to measure current.
hello
did not work for me
It doesn't work in real life. After start some apps and close it current returned to 42 ma forever.No more 5-7 ma. Only turning on Airplane mode gives 2-3ma standby. So all bad battery life comes somehow from radio is too active.
Hello all.
I hear that if u change the radio version to a down one you have more battary life ..is it true ? there is anyone that tried that?

From my experience (only 3 days rooted LOL) you have to find radio that works best with your carrier. Better reception will stop phone trying to find masts, hence improving battery.
Sent from my HTC Desire using XDA App
I don't see any problem with battery draining. If it gets you over the day, what do you need more. Over night you plug it in.
I have all switched on (location too) and no problem with music maybe 1h, reading mails, checking facebook several times surfing internet and news. I would even say its better than WM 6.5 doing the same, at least the same.
I think battery draining is not hd2 problem wp7 is the problem
the real solution for batery is - turn on 3G
try
batery life is 2 days with many calls, play and others.
22.03 - 10:00 am - charget
24.03 - 12:00 pm - charget agaen 50 hours

I know this looks unbelievable, but I noticed this before... Although I thought it is not possible and that I am crazy.... but after switching back to 3G, my battery lasts half day longer.... Why? Don't have a clue, it defies common sense, but it is like that...

I don't see any problem with battery draining. If it gets you over the day, what do you need more. Over night you plug it in.
I have all switched on (location too) and no problem with music maybe 1h, reading mails, checking facebook several times surfing internet and news. I would even say its better than WM 6.5 doing the same, at least the same.

It is definitely problem, comparing with all android ports where battery life is x2 more longer than in this "simplified" WP7!! Battery is dead in a half day in a standby is normal for you?
I solved my battery calibration issue by installing HTC battery tool, it fixes the calibration of battery so correct full charge is 100% and correct no charge is 0%. Give this a try, I am sorry I cannot post the link but I found this app on XDA too.

ok im running HD2O_1.04_DFT_LEO70_RELEASE and WAS running radio 2.15 and after 3 days testing and very poor batter life with registry fix, i decided to change my radio to 2.12. and so far after 7 hrs of testing ( full data, 3G, and internet browsing + youtube here andhier) my battery is still 3/4 change the radio it take 2 sec. to do.
with the old radio i was using, i went to work at 6a.m. got off at 3p.m. and i only had 1/4 left. with radio 2.12 i still have 3/4 and i used it more because im no longer at work.
try it good luck it worked for me
i will post another update around 6p.m. pst.
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)
Aug 30, 2011
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.
May 18
Tested XBmod 1.10 nodo - trick works perfectly right away getting 3-5ma!!!
June 02
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.
Jun 07
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!!!
Jun 17
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!
Hi,
Just ask for any other information, I'm bound to not remember to provide everything Have had this i9100 for about 30 months. No battery issues for the first two years but plenty in the past six months.
Phone would switch off suddenly (no low battery warnings) or go black / unresponsive and super-hot. Replaced the battery and after about 2 months the new battery (probably not original) was literally bent and mis-shapen. Bought a genuine (I hope) Samsung battery and installed CyanogenMod and still seeing hard power-offs when they wouldn't be expected.
See attached for this morning. Phone unplugged after charging (via USB) all night. Attempted to use Apollo and it wouldn't work so didn't even use the phone on the bus. Clearing data for Apollo after arriving at office and that is working again now. Made one long phone call before starting work and towards the end of that phone call just dropped. When arrived into the office plugged back into USB again.
Why did it power off at 70% and why wouldn't it turn on again even though after being plugged in and charged for 5 minutes it starts up at 40%?
What do you think? Is this a hardware issue and I have to give up on the phone
Does near camera get hot ? it shows media taking 21% which I assume it is not normal .
also we need to know about Rom version and recovery version .
Media scanner is the process that scans every folder and file so that if you copied or downloaded a .mp3 file it shows on your library . However for many reasons this can go wrong . Do you have folders with many files ? (talking in thousands) ... for example apps like maverick can download many thousand mapTiles that saves on internalSD or ex ... Then MediaScanner everytime needs to go trough all those many thousand files and that burns cpu/battery ...
if so try http://geeknizer.com/fix-android-media-server-scanner-sdcard-cpu-battery-drain/
other than that battery can go bad which is easily replaceable .
Attached screenshot from this morning. Notice how it drops to zero at a point. The phone switches off even though the battery isn't exhausted.
Near camera not getting hot. Not sure whether media 21% was normal or not, that morning only 30%+ of battery used when the hard switch-off event happened.
ROM is CyanogenMod 10.1.3-i9100 (Sept 23rd) and recovery is CWM v6.0.3.6
No folders with many files. Use the phone lightly really. A few MP3s, email, phone calls, general browsing, occasionally Skype.
Real question is why the drop from almost 70% battery to zero, as shown on last weeks and this mornings screenshots?
Battery is brand new, unlikely to be the problem.
Will install a battery drain app and study closer.

The most advanced app I can think of is battery monitor widget pro which can show you energy flow in mA per ( by default every 10min ) . A stock i9100 has a 1650 mA .However I don't think it can explain dropping in energy like that . No battery saving app will resolve this issue . There are some battery calibration apps around . I don't know what they exactly do ...
I have an i9100 . There has been some " Episodes " when I shut down , remove the battery and re-enter , turn on and see unexpected drops in the juice but the most extreme was dropping from 38 to 15 . Never when running android .
When phone gets superhot for not reason it sure is using alot amount of battery . I would suggest a factory reset or changing rom/recovery .
Plus I would like to know do you experience a crash ( after going dark you simply turn on the device again ) or drain battery ( which your device wont turn on until its in charge for a few seconds/minutes ) .
If everything fails I would be suspicious about mainboard .
----------------------------
On a second Look I suspect the gap you are seeing in the battery is a state when you experience a crash which loads the cpu that uses juice enough that android is running to record the gap but not functional enough to respond which result in something like the image above . I don't believe the battery can go from 70 to 0 then when you connect to a charging point you gain 50-ish % battery in a jiffie . When I think back I can say I had battery stats like that and my phone still is without issues ...
It's not getting super-hot any more. I think that was down to an old battery. What confused matters somewhat was it still got super-hot with the replacement (non-genuine) battery, which after a month or two was actually buckled out of shape. The phone was running Samsung ROM then.
Since then, have installed CyanogenMod and genuine Samsung battery and it's better behaved in general. Just these occasional crashes or whatever they are.
When it goes black, it won't turn on again, until after the phone is plugged in for a minute or two. Then it will turn on and report much higher than zero battery. It could still be some kind of looping crash where the screen is black but Android is still running. That wouldn't explain why it recovers when plugged back in though.
Since these issues are across 3 different batteries and 2 different ROMs, I'm tending to suspect that mainboard myself. And I don't trust any of the high-street phone repair places. They have two options for me: (1) sell me knock-off batteries, (2) replace mainboard.
The phone is still functional to an extent, it's just I can't rely on it. It's good for a half-day, after that I can out and about uncontactable and unable to take a snap photo or whatever on demand. Annoying!
