I'll leave it to others to give advice on which radio to use. It might be worth installing danielherrero's (one of our own developers) bandswitch application http://www.commmgrpro.com/ You could use this to limit phone to certain bands only with an easy interface. Would allow you to check out exactly what is causing the drain on battery.

thanks for helps

Sorry, got me stumped. So with no radios on the consumption is double that when wifi is on!!
Let's see if anyone else has any suggestions.
Mike

infinite loop perhaps??
What ROM/Radio versions are you running? EDIT:: seen the ROMs, perhaps try updating to a newer dopod ROM??
Also what 3rd party apps have you got installed??
(RESCO was a ***** for doing this to my TyTN)

the exact same thing happens to me. i've charged it completely, it obviously got really hot. usually at this point, i would take out the battery and let it cool off before turning the phone on, otherwise it would get even hotter and eat 300+ mA and drain the battery fast. this time i opened the wi-fi connection and immediately the battery status dropped from 332 mA to 130, and stayed down there. the phone even cooled down a bit. after i've turned off the wi-fi, it started draining and heating again. what can i do? is it a software or hardware problem? i'm using schaps 4.31, 1.47.30.10, have google maps, palringo, opera, tcpmp installed

I have the same behavior, too.
But not yesterday evening. After restarted it for the xxx time it staid at 28mA. This was so until I left the train in the morning. It went up to 347mA and I am not able to get it back to 28.
I am using the default HTC ROM "HTC_TyTN_GER_3.54.257.2_103_6275_1.47.00.10_108".
I also tried several other ROMS (Schaps, Pays ...) and different radio versions as "HERM_Radinly_1.16.00.00_CustomRUU", "HERM_Radinly_1.47.00.00_CustomRUU", "HERM_Radinly_1.47.00.10_CustomRUU", "HERM_Radinly_1.47.30.10_CustomRUU" and "HERM_Radinly_1.54.30.10_CustomRUU"
but none of them helped me out.
I also done the Exchange Server trick, deactivated 3G and even deactivated all GPRS or EDGE possibilities from provider side.

Phone gets hot
Hi,
I am not an expert but I had the same problem with my phone, I solved the problem by moving some software I had on my storage card to the internal memory, (in my case it was the encryption and additional language support software I had)
Another way is to look for the Power management tweak in this forum which helps to manage your storage cards power draining,
Sound strange but it worked for me.
Good luck

Hi,
the new battery has arrived.
There is no change in battery draining
What I recognized is, that if the battery is "cold" the power consumtion is around 28mA. But after a call it is getting warm and uses 10 time so much of power.
Please don't laugh now:
I put the battery inside my freezer for 5 minutes. Put it back inside the mobile ...
... 28mA.
If I keep it cold it stays fine for 3 days.
There must be any solution on that.

Battery Problem Blackstone

Hi, I'm new in this forum, and I don't speack English well, so I want to excuse me!
I have the new Touch HD, at the beginning I changed immediately the original ROM with a new one, I installed a lot of programs, and everything woked very well for two weeks, but then I had a big problems with battery...a the first the battery was very good, -10/15% per day, but suddenly after two weeks the battery lose 1% of its charge every 2/5 mintes...if I disconnect the power when the battery is 100%, after one hour without use (and also without wifi, BT and GPS), I have 70% of charge!
I try to change the ROM, a friend suggested me a new upgrade for Radio, but I didn't resolve my problem!
Now I buy a new battery online in htcstore, but if I put my mobile in "Fly mode" the battery work very very good!
I want to say that here normally I have the signal indicator with 2/3 nicks, so the signal is good!
Someone can help me?...someone have my same problem?
Thank you so much fo everything!
Greetings, Eddy

the battery will be used up quickly if your fone is constantly searching in and out for a 3g signal, regardless of 2g signal strength
have you got wifi on?
bluetooth?
a gps app running?
what other apps do you have running in background? some really poll the cpu a lot and will lead to battery drain
other than a dodgy battery, it must be some software running that is using up the battery

Thank you for aswering!
In background normally I have SMS o Contacs, but also if I close every programs in background the battery doesn't work well!
No, Bluetooth is OFF, GPS and WI-FI are OFF, I use telephone just with gsm!
Also when I write message, normally I write a message so long (3/4 messages), after wirting, the battery lost 10%, and I didn't have this problems at the biginning!
I left my mobile on also during the night, and in the morning I had again 100% of charge...now 100% it's a far dream!

try turning off the autoadjust for the screen and setting it at a medium setting, also make sure the backlight turns off after a minute or less.
its a huge screen and will burn up power, although saying that i watched a full length film on my HD the other day and only used 20% in 1.5hrs
if no progs are running in the background and its not a display issue (how have you checked whats running btw? need more than just WM taskmanager, try mem maid or similar) and the problem is not there when in flight mode. then i can only assume its the rom you are using, try another with a different radio rom in it
i found roms with 1.10 radio to be better than 1.09. try this rom (mulitlanguage) works good for me
http://forum.xda-developers.com/showthread.php?t=465637
edit: have you got HDTweak installed? its good to configure the data to auto turnoff after 1 minute or so (even in gsm gprs could be running)

I tried to setup the new ROM but I didn't resolve the problem!
If I leave my mobile only with GSM on, without use it, without call and sms, the battery lost 2% in 30 minutes, and it's not normal!
If I use it, change settings, write message, the battery lose 5% in five minutes!
I don't know what I have to do...this mobilie now can't live without a power connection!

I want say also that at the beginning some application in my HTC wanted "HTCAPI.dll" because they didn't found into the mobile...so I found this dll online and I did copy/paste into the directory!
It can gave me problems with battery?....I don't know how it's possible, but I don't know!

Try to buy or borrow another HD battery and compare them. You should know the problem then.

Of course, I alredy bought it online, and I'm waiting to get the shipping!
But it's very strange that a battery stop to work suddenly, but I know that there are a lot of people who have my same problem!

If i were you, i would flash back the original rom and do a hard reset. Then, without installing anything on the device, see if the problem persists.

Thank you ardsar...I want to try....can you tell me, what I have to do to obtain the original product?...without hardspl and new rom?...like the first time that I turned on this HD! Thank you so much!
For example, I have your same SPL and ROM at the moment!

Hi Ardsar, I flashed my ROM and SPL (brand), and now my mobile is like the original but....do you know Teeter?...I played 2 minutes, I completed 3 levels, and from 85% the battery is now at 79%...

Hi guys...yesterday I did a lot ot tests, but without positive results, but I fund out new problems:
1)The bettery lose a lot of charge also if my Blackstone is offline, when I use it with TouchFLO, Teeter, SMS, Settings...everytime!
2)I have near to icon of signal, the simbol of GPRS, but sometimes it changes with the simbol H and with this new symbol, the signal falls and to resolve it, I have to wait a long ore reset the mobile.
Now I'm not sure that the "target" is the battery...I don't know, I changed also the Radio ROM with new last, but the problem is not over!
Before put it into garbage case, someone can suggest me something to try?
...I will never bring it to Assistence HTC, because I will have to wait some months, and I didn't pay 500€ to have it "under repairing"

Do you have SK Tools 4.4.6 or another battery monitor installed?
With SK Tools, you can see under the sys info the current battery use. My usage is in standby with lighted display -100mA. What's normal?
My battery is also very empty. Last evening i had 54%. This morning, the phone was off, no power any more.

No, now I will try this tool!
But I think that you also have problem with battery, becase the firsts days that I had my HD, I left my mobile on the whole night with 100% and in the morning I had 100%...I had 99% at lunch time!And a lot of friends that have this mobile have the battery so strong, like me at the beginning...so...I'm getting angry

i have this problem too. had my HD for 2 weeks coming to 3 now and my battery seems to deplect very fast, totally different when i had it. could be becoz of the wallpaper and 3rd party theme i had

For me, it seems it's a software or anything else that needs so much battery power, perhaps the hotfixes or something else.
Sadly, the whole battery monitor progs don't show the needed power per running process, only the current usage. Can anyone with a "good" battery life cann post his current usage? (For expample with SK Tools System Information/battery supply)
Is the backup battery always at 0%?

Battlog
How about this. You can log your activities and see how much battery current (discharge) each application is using by the ma figure. It produces a .log file but if you change it to .txt you can open it up in a text editor.
Hope it helps.
EDIT: Just found out there is better info on it here on XDA Raphael forum. Credits to PalladiumTD for this app.

Today I tried a new battery, and also with a good battery, I have the same problem...so I think that I have to send my mobile to HTC service and ask for a new one, because it can be an internal problem, maybe of motherboard, radio, or I don't know...but it's sure that is hardware problem!

Did you a hard reset and installed nothing else?

Yes, I did...I alredy unpacked it and monday I will send it to HTC service....I hope that they will sed me a new one....a friend said to me that maybe this problem for them is called DOA (dead on arrived) and in this case they have just to change it!I hope so!....but I don't like...!
I know that I can reset it pushing the volume control ecc.....someone knows it exactly?Thank you!

problem with my camera

Hi guys I need your help for this problem.
The camera won't let me take photos using the flash leds, I tap the icon but nothing happens...it won't change.
The thing is that it worked fine and smooth until yesterday (as far as I remember), I only installed some "innocent" cabs and the hotfixes. Never changed the ROM but now, after the hotfixes, it shows me 2 different versions: when the phone starts it says 1.48.71294 but when I go in phone informations it says ROM 1.48.408.1 (71294) ITA (btw, I'm italian...). Is it the same thing or what?
Now I'm downloading the ROM from the htc support :/. Will it help? donno yet.
The phone works perfect, just this camera thingy is driving me mad. 3 or 4 hard resets didn't help.
Try help me out (I'll go up on the roof and throw my Leo far far away...).
Thx in advance.
EDIT: SOLVED

hi,
great to know your problem got solved. can you please post the solution?
thanks

Funny how it got solved: another hard reset and here I go.
Sorry but this is it.

And make sure your batter is above the minimum charge amount for the camera app to use the flash. I've seen various amounts on here, ranging from 20% to 50%. I'd suggest that if your flash isn't working in the camera app, that's probably your problem. Just make sure you're charged to at least 50%.

this is what I was mumble-mumble thinking last night but the battery was fully charged.
It seems like this smartphone is a work-in-progress but I'm positive and still consider that the price is worth.

I had the same problem: at the beginning I was scared something went wrong on my device. Later I found that under 20% the led flash is disabled by default to save battery.... try, it's the right percentage...

What solved? Share with us!

Not having the flash available under 20% is a real pain - I don't like having my hand held because HTC won't let me decide if the pic I want to take is more important or having my phone last for some extra time.
Does anybody know the registry tweak or fix to enable the flash until the battery is spent?

There's none.
The drain of the flash is so high that if it stayed active under 20% the voltage drop on the battery would most likely cause your HD2 to just shut down instantly when it gives the bright flash when taking the photo.

battery under 30% the device wont allow you to use the flash.

Possible cause and solution to X10 Battery? -"No Sleep Bug"

Hey guys,
Just updated to the x10 after my samsung galaxy died on me, so far i am rather happy - except for the lack of root, but that will come.
I have noticed many complaints on the forum about battery life, and have experienced the same thing myself. From my experience, i think this looks like the same issue that was faced on a leak of 1.6 for the galaxy - it was referred to as the "No Sleep Bug".
TBH, the name says it all - for some reason, in many builds of android 1.6, phones were not sleeping correctly. There are many theories as to why, from cpu not being allowed to sleep, to permanent communication with google servers.
Despite all these different theories, one thing seemed to fix the problem - turning off all location services. Some people argue that a different carrier build, turning off just 'share with google' under location, turning off just AGPS etc. would fix it, but from my experience, the only real way to fix the issue was to turn off all GPS usage unless you need it. The once you have used it, reboot your phone.
This fix obviously sucks, and a new fix has recently been released by a veritable android-demigod around the Galaxy.
HERE IS A THREAD ABOUT NO SLEEP ON i7500 GALAXY;
(ok, some stupid rule says i can't post links - can a mod help me out?)
HERE IS THE FIX FOR THAT PARTICULAR BUG;
(ok, some stupid rule says i can't post links - can a mod help me out?)
LINKS ARE IN POST #5 - THANKS TO ONDOTEAM (would still be nice to get them in this original post though)
Now, from my experience, no sleep behave exactly the same way on the x10 as it does on the Galaxy;
1) I turn of all location services, and my battery life at least doubles.
2) After said turning off of services, 'spare parts' no longer says 100% running time under battery usage - in fact it can be as low as 10%.
These two factors are identical to my experience with Galaxy. SO; is there any way drakaz's fix can be applied to our X10's? It seems to me that the files he mods are standard Android system files, not sony/samsung specific.
Now i am no developer, so i dont know it this is possible - the first question that comes to mind for me is "do we need root access, or can this be done through developer tools using the android SDK?"
Can anyone help shed anymore light on this?

Seems to work for me. I disabled all location services. Spare Parts went down from 100% to 7.6%.
I'll just have to enable GPS when I need to use it..

Awesome! Glad to hear it has helped.
Let's keep testing this guys - if it does show up to be a big cause, then perhaps the devs around this place can help is figure out a patch for Drakas' mod to make it work with our x10's!

No sleep is easy to fix, took me a while to figure it...
Turn your screen brightness from manual to auto, spare parts will now start showing proper running stats, no more 100% running.
The screen is a little dark in auto but it will cure the 100% running.
GPS and location services etc make no difference to my X10i, I am running the 1.6 version unbranded UK handset, the only thing to stop mine running 100% is to put the screen on Auto.

My phone came out of the box with auto-brightness and i never changed that option, yet i still had no sleep.
Drakaz has done some fairly deep digging and is next to certain that it is an artefact of the geolocation bug discussed in the thread in which the problem was fixed.

Although I'd half assumed that they were referring to the total "up-time" figure which you can see at the bottom of the "about phone"; "Status" screen.. But perhaps not.?

Spare Parts is a standalone Program ...
(i don't know for sure if it is in the market or downloadable as .apk from somewhere here in the forum ...)

You can download it here

Spare parts is indeed available from the market - it is a much more powerful tool for indicating battery usage than the regular android methods. The galaxy stared on 1.5 which had NO indicator of battery usage statistics at all, so we all learned about spare parts very fast.
Perhaps that is why no x10 users have realised about the potential no sleep bug; because so far only the android usage indicators have been used?...
Anyway, hopefully this can help us all understand the way our phones are working better together

14% it's mine value for running time, not 100%. By the way thats 30 minutes of 210 in total :S

I'm also experiencing "No sleep bug" after i used GPS. I use Battery Graph to plot my power consumption and after I use GPS, I can clearly see that power consumption is high even if i turn the phone in plane mode.
In addition SE widget, used to turn on/off GPS, seems to not work very well for me. So, to fix the bug, i manually disable GPS in parameter menu and restart my phone. After that power consumption is hardly null (20% in 8h with MP3 on almost all the time).

Do you have 3G always on?

My phone has no trouble sleeping.
Gps hasn't really been an issue but I keep it off when not needed.
Here's my solid settings:
1) No auto sync
2) No moxier
3) Gps off
4) Restart after using wireless
As long as it's like this my phone lasts 2 days easily

I have been playing with mine for a month to work out what caused mine to not go into sleep, I keep GPS wifi etc on 24/7 but in spare parts I was running 100%, after numerous reinstalls and removing everything i chanced on turning on auto screen brightness, now when i unplug my x10 the running sits at the correct level.
No Geolocation bug here

I have this problem with 100% on and off. Sometimes when I check its under control (~10%), other times its at 100%. I have GPS off, no WiFi, auto brightness... don't know why it sometimes just gets stuck at 100% :/

Answer to bad battery life: phone never enters sleep state

Hi,
i noticed months ago the following on my IDEOS X5 (german) concerning bad battery life. It could be the reason why there are so many different reports regarding bettery lifetime of the U8800.
First - why did I start to investigate: because the phone sucked about 5-10% per hour while not beeing used / lying on my desk, so after max 20 hours the battery was empty. But this did/does not always happen....
What I did: it took some time to get used to android (its my first droid) and learn how to troubleshoot. A month after I got this phone I learned that the GSM-code *#*#4636#*#* will show you very useful information concenring battery/phone usage. I started to play around with the phone (factory reset, install/remove apps, enable/disable different options like 2G/3G/WLAN etc...) always keeping an eye on the 4636-infos.
Result: When I use WLAN the phone simetimes enters an "state" when it never again enters "sleep state" and the battery gets sucked as stated above. I switched off WLAN for a week and this did not occur while standby time increased to 48 hours and 4636 stated an "phone awake" percentage of below 20% (normal usage). Once I reenabled WLAN again it took about an day of WLAN usage to reproduce the bug and "phone awake" time increased to 100% while standby time decreased to below 20 hours. ONLY rebooting the device recovers from this "state". I further noticed that this does not happen if just WLAN is available but no 2G/3G (phone had no SIM). My conclusion is, that the
"You May Be Charged"-Popup is the culprit. It does lock the phone to this "state" for some reason, mybe when the WLAN connection is dropped while the phone is not used (traveling). Can someone reproduce this on his phone (maybe not german)?
Resolution: IMHO none. I send the device twice to reseller for service. First time the complete mainboard was changed without success regarding the battery drain. Second time nothing was done - they just returned the device to me.
Thanks.

This is a known problem, that already has a thread...
http://forum.xda-developers.com/showthread.php?t=1043760
This is affecting ALL Froyo Roms, if you want battery life, install Oxygen or CM7...which are based on Gingerbread.
There is no point in discussing this issue anymore, this is a very well known problem and Huawei doesn't care.
Sending the phone back to manufacturer won't help at all.

Thank you for the hint - it realy looks like the same issue. Knowing more about the nature of this issue could give people not willing to install custom roms a possible solution. Can someone move this thread over to that one?

I hope some more bugs are straightened out like headphones and internal mic at the same time. Headset button to work. Battery time!

none of my android phones could use the phone's mic when headphones were plugged in

I saw a solution for the mic-with-headphones-problem a few days ago, either here or at modaco (do not know if it is confirmed working though).
fajabird, I know that you want this to work with the ROMs provided by Huawei. Huawei obviously does not care too much about providing the community with updates (they do not even have gingerbread-support by now). This is the downside of this low priced phone.
Let me just say this: It took me about one hour to understand the ultimate-guide at modaco. It took me another hour to decide which ROM I want to use. If anything goes wrong at the installation I can easily start over again. Now I have a fully working phone with Android 2.3.5 with a battery that lasts at least 2 days, sometimes 3(if I do not play any games within that time). Of course I understand that you are probably very pissed at Huawei for providing a ROM with a bug that serious.

if you find that fix again, let us know where to look

Hi, thank you for sharing your experience with me. I always wanted to update to some custom roms but the time I started investigating this issue there was no stable one out there. On the other hand I thought there might be a dev interessted in more details regarding this issue helping him to sort out this nasty bug for whatever reason.
Can someone tell me, if his U8800 also has the ambient light sensor but like mine does: it won't reduce the brightness, just increase works. Thanks.

Mine reduces brightness but does it quite weird sometimes like adjusting several times without the light around me changing...

Mine always adjusts it way too low. If I am inside the brightness is always on minimum. I use the power-widget on the homescreen. I only change it at night, it is on max. for the whole day (the max. brightness is still kinda low, especially if it's sunny).

I started to play around with the phone (factory reset, install/remove apps, enable/disable different options like 2G/3G/WLAN etc...) always keeping an eye on the 4636-infos.
Result: When I use WLAN the phone simetimes enters an "state" when it never again enters "sleep state" and the battery gets sucked as stated above. I switched off WLAN for a week and this did not occur while standby time increased to 48 hours and 4636 stated an "phone awake" percentage of below 20% (normal usage). Once I reenabled WLAN again it took about an day of WLAN usage to reproduce the bug and "phone awake" time increased to 100% while standby time decreased to below 20 hours. ONLY rebooting the device recovers from this "state". I further noticed that this does not happen if just WLAN is available but no 2G/3G (phone had no SIM). My conclusion is, that the
"You May Be Charged"-Popup is the culprit. It does lock the phone to this "state" for some reason, mybe when the WLAN connection is dropped while the phone is not used (traveling). Can someone reproduce this on his phone (maybe not german)?
Resolution: IMHO none. I send the device twice to reseller for service. First time the complete mainboard was changed without success regarding the battery drain. Second time nothing was done - they just returned the device to me.
Thanks.

Hey there friend, I've detailed much of this and been through a lot of troubleshooting. It did not appear to be the "You may be charged" popup as I disabled that whenever I changed ROMs. I never did get a solution for any of the Huawei ROMs, it just seemed like bad code as Dzo pointed out with the WiFi driver.
A very simple solution for me was installing one of the 2.3 ROMs, they are quite stable at the moment, especially Oxygen (although I use MIUI). You will find much better battery life with these.
Best of luck,
Ryan

My stock rom 2.2.1 Shows Android System 97% battery usage and battery drains 50% in 19minutes! With wi-fi, 3g, Bluetooth, everything is off and even i do not use it.

Flash latest official 2.2.2, wait for official 2.3, flash the custom 2.2.2 rom void or flash a custom 2.3 rom. I would recommend flashing the latest 138 or 162 to get the latest modem baseband or manually install the AMSS.bin.

I formated it via phone, then via PC - it works in powered on phone in android, but in recovery it doesn't it only sees sdcard as internal memory, if i try mount sd-ext shows error, can't mount.
Also i have problem if i use pc to copy some files to internal memory-phone switches storage mode OFF! and i can't copy files to internal 2GB memory..strange
