Battery/ Standby problems since a few days

Hi all
I expirence a strange problem I can't really explain to my self.
For two weeks now my XDA looses battery quiet rapid. I goes from 100% downto 25% in a matter of 8 hours... this hasn't been the case before.
I tried to do a hardreset and this fixed the problem for a new days, now it appeared again.
The standby problem is only when the phone is turn on, but I do have good network coverage, so the phone is not always searching or something. I don't have GPRS connected, no bluetooth or something and didn't install new software, there are no additional tasks running in the background.
Actually I would like to wait for a german 1.72 ROM before a upgrade the nexttime ( current is 1.60 )
Does anybody has an idea ????
Help is greatly appreciated !!!!
Alex

Hi Alex,
i have experienced the same problem since several weeks.
I have made a hardreset, Firmware update to the actual o2 Version (1.66.01GER, 1.10.00 Radio), and so on without a better result.
I suppose that it could depend on the o2 Network.
Two weeks ago on vacation in foreign networks the standby time was o.k.
The o2 Hotline has no information about this phenomenon until now.
Regards
Markus

Arrgh ****...
I was in a "foreign" country for nine months... just when I came back it started...
It seems fixed after a hardreset for a day or so, then it starts again...
I tried this new ROM, it's simply horrible, was totaly unstable, I switch back to 1.60.
I also thought I could be related to the network... this would not be good.
I am here in the office on the boarder of my homezone, someday I have homezone, some not... (shouldn't be the case either )
But my other mobile also behaves strange, it switches ( with homezone indicator on !!! ) to t-mobile... even I have a strong O2 signal...
I think it's time to write a mail to customer support...

Bah... is a fantastic PDA, but I must charge the battery every 2 days...
I think is normal...

I had to recharge very second day... that's normal if you use your pda...
but we are talking about 8hours and less without using it !!!
:evil: :evil: :evil:

Try switching on flight mode and see if it is better.
One thing I learned but not sure if it is scientific: don't xray scan your phone/pda when passing customs. My Siemems phone started behaving cranky when it gets scanned.
Lastly, if still as bad, suggest you send in to check it up. Hope just some problem with the battery. :roll:

Thanks.. but as I have allready written... when I turn flight mode on (same as turn the phone off) the battery is OK.
It has definitvely something to do with the radio.
The phone didn't get xrayed for a while now :wink:

Interference
It doesn't have to be an X-Ray machine Bro. Any form of frequency interference can screw your Xda's radio - but usually it will get back to normal after awhile (days) unless it is subjected to severe exposures.
What you can try to do is to goto Start-Settings-Personal-Phone-Network.
From Preferred Networks hit Set Networks - reprioritize.
Then under Network Selection change to Manual once the Xda gets hold of a signal switch back to Automatic.
Lastly check if your Broadcast Channels is enabled - disable it.
Worked for me after hours in the OR once - oops!

I have the very same problem for a few weeks now. Some more observations:
- power goes down at a rate of 1% every 12 minutes
- happens only with an O2 SIM. If I put in a D2 SIM, everything is fine
- happens with every O2 SIM - I tried three so far
- my O2 SIM works nicely in a friend's Himalaya
- bought a new battery - didn't help
- putting it right next to a speaker (so that you can hear all network activity) shows that there is not more activity than normal.
- problem is present with both 1.60ger and 1.66ger O2 firmware, with no software installed (i.e., directly after a hard reset)
I would be grateful for any tips or hints how to solve this! Also, if someone else experiences the same problem, please post here. Maybe it's a hardware problem, and the more people experience it, the easier it'll be to convince T-Mobile/O2 that there's a real problem.
Cheers
Daniel

News on this issue: I just flashed the Imate 1.72 ROM version, and at the moment it seems this resolved the problem. The 1.72 has a newer Radio ROM (version 1.14 rather than 1.10) than all 1.6x versions, so this could make the difference.
However, it is also possible that the effect is only temporarily gone, due to not having configured GPRS, SMS, whatnot for the O2 network yet, so it is too early to start partying...
And, of course, the OS is now English rather than German.
I will now leave my Himalaya alone for another few hours, just to confirm the problem is currently really gone, then I will start configuring it back to O2 settings, and add back all my software. This will take some time, as I want to check for the problem between all steps, and each check takes around one hour.
So, to all who suffer from the same problem: I suggest you wait a few more days before you upgrade. After I have finished my testing, I will post here again the results.
Let's hope 1.72 really does the trick!
Cheers
Daniel

More news: I am now pretty sure that (again) the Homezone application is at fault!
The battery drain we experience roughly matches the power consumption of the CPU when not in a sleep mode. So, it seems the Homezone application prevents the CPU to go to sleep mode.
Why that used to work, and only started happening some weeks ago, I don't know. My guess is that O2 slightly changed the way they broadcast the location info. That location info is sent every few seconds via Cell Broadcast on channel 221, and as the Homezone application has to read that, it's quite plausible that it gets woken up every few seconds (whenever a new broadcast arrives).
What surprises me, though, is that there seem to be relatively few XDA II owners on O2 who experience the problem. I will send an email to O2 support and ask them.
In the meantime, to correct the problem, uninstall the Homezone application. To do so, do the following:
- deactivate the Homezone display, using the "Homezone" program
- using the file manager of your choice, go to the Windows directory, find the file "OHZ.dll", and rename it to whatever you like. This step is important!
- soft reset your XDA II
- go to "Einstellungen" -> "System" -> "Programme entfernen", and remove the program called "V2R Homezone"
- with your file manager, go to the Windows directory again and remove the renamed OHZ.dll file. If there is still a directory called "Windows\V2R\HZ", remove that also.
Of course, you lose the Homezone display. But you get full battery life back!
Cheers
Daniel

Okay, I'm trying to find out why not everybody on the German O2 network is affected.
Alex and Markus: I opened a thread for this over in the PPC-Welt forum, see here.
You are invited to come over and participate! If you are not interested, could you please let me know where exactly you are located? I live in Munich, and it might be that O2 misconfigured just a few base stations here in the south of Germany so that the Homezone application behaves erratically.
Thanks!
Daniel

Hi Tazido
Fu#$%^&*( is it really because it move to munich... arrgh.
I do live in Starnberg, but I spend the weekend in Ludwigshafen and here everything was OK.

As mentioned in a post in that other forum, everybody who is affected should call the O2 hotline and report this as a "network problem", to raise O2's awareness of the situation.
For the moiment, uninstalling the Homezone app is the best you can do. :-(
Cheers
Daniel

I did uninstall the O2 Homezone app.
I tried to mail to O2 but this seems not to work for some reason, I get a 403 error.
About calling the hotline, I have to pay for this, as I switch to the web-based contract with the free SMS, so as long as i doesn't get worse I can live...

sms with delay

Hi there, due to the fact that the search option doesn't work with less then 4 characters, i can't search for "sms".
But here's my real problem:
I've flashed different roms into my mda vario, after unlocking it. First the Molski.biz rom, then the last original t-mobile rom, but it was toooo slow, i've imediatly deleted it, en flashed the mr clean rom.
But in all roms i have some delay in recieving sms-messages.
Half the time they appear directly after they were sent by my friends, but sometimes i get them after a few hours. for example: it was sent at 15:00, and i received it at 17:30.
And sometimes i don't get any sms-messages, and after an soft-reset, i get 10 at one time, all delayed.
does anyone know what to do about it? or what causes it?
Regards,
Twan

i sometimes get this too though not often its usually when my phone loses signal and when it comes back into signal it wont recevie txt messages until i soft reset or send another txt out then ill get like 4 all at once lol.
Wizard isnt the best phone for txtin i must say as i send a good 1,000 txts a month and so far its poor.

Sounds like a network issue to me...
The network isn't registering the phone or something similar. For SMS the towers "push" the messages to the phone. Queuing them when they don't detect the phone on the network. If the phone is on the network and not getting the messages until it is reset and forced to re-acquire its signal than it is a network problem.
I've seen this problem on a few networks regardless of phone make and model.

I would agree with the above, its a provider issue not a phone issue.
I have a debate with Orange about 10 years ago about not getting text messeges when I loose and then regain service. I was told that when a text is sent to a phone that is off or lost a signal the message is stored until a set time has passed and then delivery is retried, thus getting all the messages at once. The way 'around' this is the disconnect the phone from the network and re-connect. This forces a scan of the message queues and again you will get all messages in one go.
I would assume going in to Flight Mode and back will do the same thing as a soft boot, but I have not tested this.

Okay,
so i could suggest it's not quitte an rom- or wizzard-issue, but a network-issue.
I also think going to flightmode and back will solve the problem. So we will hear from you if that's a solution?
I'm busy reflashing a new rom into my wizzard.

I've tried, but now there's nobody who has sent me an sms
ghehe, i'll wait....
but i do think it will work.
i'll keep you posted

This is happening to me all of a sudden and its not a network issue. I have 4 phones on my account and i texted between all of them and only my phone won't get the messages UNLESS I reboot my phone or use smartskey to close a window.
Here is the strange part, when a text message is sent to my phone, the screen turns on, but doesn't show the message pop.
Is smartskey blocking it?
Also, closing a window by clicking on the X also kicks the message to come through

Phone freezing

Hi,
I have a big problem with my Tytn (sorry if this is already been posted). Quite often the phone freezes, making it impossible to turn on again. The only thing that works is a soft-reset. What is worse, is that when the phone is in this state, although the green light is regularly flashing, it is unable to get phone calls even if the caller gets the normal ringing signal. No trace is left of the call, neither in calls list! This is a really serious issue: please, let me know if you have an idea of how to solve the problem.
Thanks!

I am having the same issue. I haven't been able to isolate it. I was havign to0 restart 1-2 times a day. Same systems press the power button nothing. Lights blinking everything looks ok. but nothing on the screen. and i miss calls. really pain in the ass. I loaded mobile secretary and it hasn;t locked in a day or two which is odd.
I also sometimes have to rpess the power button two times for it to wake

me too
It's happening to me too. I will lose service and the phone doesn't go out and poll automatically when service should be good. It may show 1, 2, 3 bars then when I try to make a call it hangs, and then get an x and a Y!, then searches for service. I have the GSM only hack installed and the activesync workaround and it still does this. It is not useable as a phone.

do a search in this forum.
one relevant thread here:
http://forum.xda-developers.com/showthread.php?t=285974

With all due respect, there is no solution where the link leads to.
I am having the GSM problem also. Just from time to time I am noticing an exclamation mark near the 'antennae' icon in the top bar. When I tap it, I read 'Service unavailable' in the balloon. From that point I may either soft-reset, or switch GSM flight mode on and off, which brings the PIN code keyboard and the phone works again.
I really don't think it is related to power saving, as it happened a few times in the car with TyTN on external power.

I think warmkiwi's link may be relevant to jimwormold's original post, which may not be related to your and angled1's problem of failing to poll correctly after dropping it's signal.
Mike

yes, it was. sorry, i should have quoted the original author (jimwormold)

well, sorry for being so picky on you :|
Now when we have defragmented the conversation I wonder if the GSM problem is reported more widely? and what is supposed to do in order to isolate the problem and fix it...?

Sorry to do a "me too" posting, but I experience the exact same symptoms. There is no obvious pattern to when this happens, but it is a major problem, as there is no way (other than trying to switch it on) to distinguish whether the phone is working or not at any given moment.
I am running the latest (South African) ROM on my Vario II.

Given this thread now appears to have two distinct issues running together I better be clear that I am referring to the lock-up/freezing issue not the dropped GSM signal issue!!
To be honest there are quite a few possible causes for the freezing issue(s). I would suggest searches and the wiki on such things as (and you may or may not have tried some already):
1. Use of a Task Manager to properly shut running programmes otherwise they contiue to run in the background
2. Proper shutting down of Active Sync in addition to any task manager you may have, as it can re-start itself automatically (particularly overnight. Look for the "Fake Server Trick")
3. Always shut down Wifi when not in use (vital particularly overnight but also good practice to avoid lock ups)
4 For overnight and possibly other quiet times you can consider having your device automatically perform a soft reset to clear any running programmes that may block alarms/receipt of mail etc. Look for such things as xbar or SK schema

Yes indeed, although I think that both: a Phone App problem, and a GSM signal problem, are indeed the same, maybe only differently percepted and described by users affected.
I need ActiveSync to be running in order for DirectPush to work. If it conflicts with the phone, it makes the device unusable concerning push email functionality.

I agree they may be cause and effect for some folks. Although I don't believe we can say that all the freezing and lock-ups are due to dropped GSM signal and freezing when failing to re-establish it. The items I list either taken together or individually have been found by others to work in some cases.
I appreciate that if you require Active Sync running then this is not a solution for you. I think the issue of crashing on loss of signal requires more analysis and I'm not aware of much discussion of it - though I could be wrong!!

I was fiddling with the phone yesterday and today, and I have a hypothesis that my problem is related to PIN entry screen that won't pop up but is silently awaiting a PIN underneath.
I was trying to ucheck the "Require PIN when phone is used" box in Settings but with no luck, my PIN is then refused with "Unknown SIM Error" message. Maybe it wants a PUK but I don't have it on hand to try.
My plan now is to:
- uninstall all Phone-related applications (PhonePlus, Dark_Blue Buttons, EZDial),
- request PUK from my office and try to uncheck the box,
- try prepaid SIM card which has no PIN
To observe symptoms I need two-three days, so I will rather not be posting until solid data is collected.
ps Mike, it is a pleasure to be on a board with people like you.

new phone
I'm on day 2 of my replacement phone from Cingular and the problem with losing gsm signal is non existent. The problem was hardware and fixed by calling and getting a warranty replacement phone. I'll let you know if the problem returns. Oh, and I have not been using the gsm only hack. I'm trying to see if the phone will work as designed first.

I am reporting from the test field that my problem persists, despite uninstalling all phone-related extenders.
I have noticed that freezing is paired with disabling Bluetooth. So after switching the phone off (flight mode on) and back on (flight mode off), I also have to turn on Bluetooth.
EDIT: I was grounded for last few days at home and freezing problem was not occuring. I am now thinking that it may be related to switching band between GPRS and UMTS. My next step will be disabling UMTS for good. It saves a whole lotta battery, by the way. I am for the third day mostly on standby, with a few calls made, and I am still on 70%! (no 3G in the area)
I have contacted my vendor and asked about replacement policy, they are "checking this with the importer". It's a beauty of living in not-so-western country. Poland is the name.

I'm having exactly the same problem, very annoying because the staus LEDs keep blinking as normal. I too think the problem is UMST-GPRS switching related, as I also have problems when phoning while I drive with my car from a UMTS enabled into a GPRS only zone. The voice call is interupted and I get a loud noise, sounding like a scrambled voice, on both sides of the connection. At home my UMTS signal is very weak, so I think it happens when I move around the house to a place where the TyTN switches to GPRS.
I've put my TyTN to "GSM network" only now to see if this helps, but I use UMTS frequently so this is no long term solution for me.

Hi,
mine was siffering of freezing issue, I sent a mail to HTC support, they don't know about it but the guy said me that I must to hard reset my device. Then no more freezes, I will keep testing it.

BTW: I changed my old and almost destroyed SIM card by a new one.

My touch hd keeps dropping calls

Hey,
Has anyone else had problems with their HD suddenly cutting of calls even though there is good network coverage? I can have 5 bars of network on the phone, receive a phonecall, talk for a while, then suddenly have the bars drop to 0 and the call being ended. It's getting really annoying at this point.
Also I think the speed of the surfing through network (gprs/edge/hsdpa) has slowed down; it feels as if it doesn't really establish a great connection with the network.
Please tell me you've had this problem and that it's a software issue that is fixable!

Its your 3g network that is dropping calls. I have same problem.
Go to settings, phone and then choose the band tab. Change network from Auto to GSM.
Solves all problems.
I have poor 3g in my home. At home I use gsm mode and when i go back out i switch to auto - 3g mode.

Or it might be because of an old SIM card. If you had yours for a couple of years for example, it might be time to ask for a new one.

i've actually had my sim card for ages, gonna try to order a new one and see if that solves it, thanks for the tip

Let us know!

got the HD and it droped calls all the time. My SIM-card was 5 years old. after changing it worked a lot better but not 100%. Solved that after disabling 3g (bad 3g rec at home), now it works as it should no more dropped calls.

You know.. it would be ideal to have an app that could be assigned to a button press that switches the 3g on and off without needing to go into settings all the time.
I don't use the 3g stuff all that often (mostly wifi) and gsm is fine for sending texts and making calls. Not so sire about mms though.
To be alle to switch it on and off would be ideal and could be used in conjunction with other software to schedule locations or times that would auto switch.
Anyone know of any thing?

i have got the same problem. I have sent my hd to manufacture on warranty. I still waiting on my phone, i let you know what is going on when it will be back to me.
P.S.
sorry about my english

Desperate
Hello to all,
I am having completly same issue with my touch hd.
Expierincing line drops, other side hear me badly or not at all. I tried to update radio roms to 1.09.25.35 and 1.10.25.25 , but ittis the same. Also tried updating ROM to DUTTY HD 1.7.,but it was the same. My network is MTS in Serbia.
Than, I changed finding netwotk to manual, and type of band to GSM (900+1800) UMTS (2100), same result . It looks that this helps a litlle, since I expierence less drops, but I am still unavliable sometimes. Also since my gsm card is 7 years old, I was adviced to change it what I did as well.
This brought even more results, but today, after 5 days of good work in one place (with good reception of 3G) I travell to another city, and you may guess, It started happen again.
All the way phone was loosing signal, calls were droping or even I was unable to make any calls as well.
I am so desperate, and will have to return it to a dealer, although it was my last option...

My was the same problem but it was fix
After I installed couples of upgrade my HD from HTC website and I recieved too many drop call so I uninstalled all the Hot fix . Now every work back to the normal way

Tried that as well, made 2 times hard reset, but no help.
Anyway I had only ine hotfix installed the one for keyboard lag.
I had imprssion in the begining that my problems started with new connection manager database (hotfix that was automaticly installed), but after hard reset everything repeated, so that was not the case....

Same problem here! Total nightmare, is there any possible fix for this or is it just poor quality gsm bits in the phone? Mine picks up such lower signal than any other phone ive had

Ryanmt, It looks that GSM module sucks...Everything else is superb, but, after all this is a phone, isn't it?
I reversed to original ROM (403 WWE), and RADIO ROM (1.09.25.14), removed HardSPL, and now waiting for asome bright idea to try...
I give myself 7 days before waranty claim...
CORRECTION: I left mine HD for warantty today (11.02.), will report on...

Mine went back for warrenty also. Mine went back due to a faulty screen but i noted down it had major signal issues too.
Have you had any update?

I am still waiting for mine. Don't know how long usually takes. Any expiriences?

Im still waiting now is 24th day, but i had sent by carphonewarehouse next time i will send straitgh to htc because cpw is not good.

24 days !? OMG, I hope I won't be that luck. I gave mysef my HD directly to official distributor (same place wher I have bought it) here in Serbia, this is 5th day since I have left it...

HTC told me 5 days from when they receive it.

Sent mine away also
I was experiencing the same problems, even when I had signal it was impossible to call someone(not always but it happends sometimes) and for some reason my FM Radio wasn't working.. I'll try to keep you all informed, if it helped to sent it back to htc..

sounds like htc might be collecting a nice pile of phones with the same symptoms. I wonder if that will prompt them to release a fix of some sort

BIG GSM PROBLEM (Glofiish X610)

Hi guys,
i have a big issue concerning the incoming calls on my phone. When my Phone is in standby mode, there is a HUGE probability that i wont recieve any call. I have the device for 4 days now and today i tried to call myself many many times and i can say that the PDA revieves only about 50% of the calls i try to make. For the other 50% i only get to hear the Mailbox after waiting a while. A few minutes later i recieve a sms on my mobile that i had a missed call on the mailbox. So I think this crap cell phone does turn the GSM power too low while in standy mode. While not being in standby mode i can recieve as good as every incoming call. Do you know if there is a way to adjust the GSM signal strength?
Actually the phone suits my needs quite well besides of that issue, so actually i'd rather like to fix that issue instead of returning that phone to the reseller
PS: I m on a 1800 GSM network and didnt make changes to the ROM.

HI man

Try a hard reset and see if that solves the problem.

It's common problem of Eten X600, Eten X650 and Eten X610
I have in hands Eten X650 some time ago - it does not recognize my SIM card at all. just "No SIM" on today screen. with another SIM card it start to skip calls.
Also a lot of users have this problem with GSM.
