No service!

I am new to android devices and i bought an HTC desire.
I have the device for about 2 weeks now and I am noticing more and more that it gives me no service in areas where the network should be perfect,i have to restart the device to get service again.is anyone facing a similar issue?

i got that just yesterday.. wasn't sure why.. I restarted the phone and Service came back.. just thought it was an oddity until you posted. how weird.

Happens to me when I'll be indoors (where there's 0 reception) and I go outside again, the phone doesn't always lock onto a network for whatever reason. Quick way around instead of restarting the phone is to enable Flight Mode (settings > wireless > flight mode) and disable it again to turn on the phone radio.

i noticed that also, when i use an elevator it sometimes does not get the network after i go out.this is becoming an issue for me because i have to keep checking if the phone is working or not.
thanks for the tip ,makes the process easier

You could also try rooting your phone and then flashing a different compatible radio rom version as this could improve certain conditions such as GPS strength, Reception, Battery life, Wi-Fi, etc.

I have a stock Desire locked in Vodafone, just did the last Firmware over the air Update and the radio updated from the worst version 5.0.0.something to 6.0.0.02 (I think, not the latest, the one before that).
Reception improoved, not by much, but to some extent. But now it prefferes to jump faster to GPRS data than before. So when I move around the house some people might get a busy tone because weather or mail is updating, and THIS IS FRUSTRATING ...
I tried from the *#*#info#*#* menu to limit it to GSM (PRL) but it made no difference.
Also it gets hot, 10 minutes of internet browsing through wi-fi/3g gets it up to 35 37Celsius and that is HOT ... Is this normal ?

Yeah - I noticed this over the weekend too.
Not for calls, but just for data.
I think it might be to do with Juice Defender.
I actually did a factory reset, just to get my data to work again.
Same problem occurred this morning, so I binned Juice Defender, and it worked immediately afterwards.
FWIW, mines is a TMob Desire...

Actually I did not want to root it since rumors have it that there will be an update on the 23rd of this month to Froyo

I was using a different Radio version but have not flashed back to the original stock version (04.00.05.11) already, after browsing for 10 mins or so, the battery temp rises to a max of 29.5 degrees celcius, which is more reasonable than 35-37 degrees celcius. Sticking with this version for now.

Having the same problem the data goes off all the time and i have to restart to get it back on. recently my phone has been getting hot after very little use.
I am rooted running froyo with the latest radio.

It happened to me today .I am on stock 2.2 , no root. I take the phone from pocket and try to call , its does not go . Now I look into phone and it says "No service " .What crap ? . Now restarted the phone and service is back .The Android is not stable enough still .Basic things like calling should be rock stable .

Should my phone always be communicating via 3g?

Even when my phone is 'idle' it seems to be communicating over 3g. Is is normal or is there something I can do, I'm looking to tweak my phone to optimize battery life.
I've already gone through the guide telling me how to optimize my battery. Does anyone have any additional tips on how to optimize battery? Thanks in advance.

Did you shut off autosync for the Facebook for HTC Sense? Seems that thing keeps trying to update I noticed that mine was running like crazy until I shut that off.

I was having same issue and found that the people app was causing data usage. After I killed it data stopped, app still runs fine when launched but seems to only happen on first boot.

I'm having the same issue, i used 300mb of data today and i really didn't even use my phone all that often. I have fresh .3 and full root with nand unlocked. Now is there an app that will monitor bandwidth usage s o i can see which app is chewing my bandwidth? As odd as it seams i think this is just a bug, i tried to capture data use when the 3g data lite was on but it showed minimal (under 60kb in 30 min)usage, its really kind of strange. for now i just turned off data.
On another note, I'm noticing something very very odd with my phone... even after i kill WIFI tethering app my pc is still connected and i can still use data, its odd.

Does wifi kill battery faster?

Does using wifi drain the battery? Is it better than using the actual 3G or 4G?
Sent from my HTC Vision using XDA App

I'm sure someone has a way more technical answer but I would think not. I have no issues with drainage on wifi, as on 2g its on the network constantly and not continually searching for towers.

If you are connected to a wifi network, it saved much more battery than using 3 or 4g. However, if you leave wifi on but don't connect to a network, it will drain battery

ok cool thanks alot man. Idk when I'm home I just like using wifi better, correct me if I'm wrong but it seems faster. Thanks again

Turning on anything more than necessary will kill your battery faster. Not always by a lot but everything does and wifi wouldn't always be faster because it depends on the wifi's local area connection. Best way to save battery is to go in settings/applications/manage applications the force close anything you don't need running. Make sure you know what it is you're closing or you could run into some problems. If you end up killing a system app and it won't reopen itself, its nothing a reboot won't fix.

DO NOT DO THIS.
Android has its own automatic task management system, and its best if you just let it do what it does best: manage on its own.
Sent from my T-Mobile G2 running Cyanogenmod.

Well gee I do it all the time and it works fine. If it wasn't intended to be used I don't think it would come without root permissions and anyone who isn't an idiot will realize that force closing android system will cause problems. But if you wanna suggest a task manager that doesn't actually kill apps and adds some bloat ware, be my guest.

He's not going to recommend another task manager/killer, because Android already does it by itself. Plus, killing a task that is not finished just causes it to respawn. Task killers are unnecessary, and may actually hurt performance and battery life.

I agree that it's best to let Android clean it's own house normally, however I'm getting a little bit jarred off with certain apps starting themselves up at boot-time.
Paypal app for some reason has installed a service on my phone, despite the fact I've never even logged into it and I can't see why it would need a service running all the time.
Also since the latest Google Maps upgrade there seems to be something under my running tasks called Rate Places. I've not used the check-in service on GMaps at all, nor will I ever.
As well as this, since I've been running a modded CM ROM (SparksMod Extra Hot Sauce) then I constantly have Wi-Fi Calling running - again this is useless to me cos I'm not on TMob US.
Any suggestions for a decent app which can stop all these things running before they ever start, and keep them stopped?

Try "Autorun Manager"
I use it, but SOME apps will auto-restart. I think you need the Pay version of Autorun Manager to prevent those from re-launching.
I use the free version, and it gets rid of some of the problem.

WiFi is definitely causing massive battery drain on my G2 with CM6.1.1. I leave it on at night, and if I have 50% when I go to sleep, I'm down to 3% in the morning. Without doing anything.
I'm not quite sure why this is happening, but it is, and it sucks. I can't go back on 3G/4G right now because I'm at just about 4.8GB, and I don't want to go over my 5GB soft cap.
I wish I knew why WiFi was causing such battery drain...

Do you have anything updating automatically (Email, facebook, etc)? That would be my best guess. I leave wifi on when I'm at home and it isn't that bad at all. Also, I'm sure theres an app out there to let you see what is using the wifi for updates and such. I just don't know of one off the top of my head. I have an app like that for 3G data but it doesn't do wifi.

I just went through every one of my apps to make sure that nothing is set to sync, except Google Voice and Email. My battery is at 50% right now, so we'll see what it's at tomorrow morning.
As you can see from the screenshot, WiFi is using quite a bit of battery. I'm not sure why, but hopefully soon (after some testing) I'll have my answer.

Yup, 2 nights in a row, my battery has gone from 40% to dead, simply from sitting on my night stand. I wonder if this is why T-Mobile discontinued the G2... because they knew it would have battery issues, and they didn't want to deal with serving warranties? Hmmm...

Its a bit of a leap of logic to link your personal battery issue with T-Mob discontinuing the phone. T-Mob has a good number of Android phones coming out in the near future, with T-Mob really ramping up their support of Android devices. So its been very reasonably speculated that they are discontinuing the G2 in order to make room in their lineup (and stockrooms, etc.) for the new phones.
I get a full day of moderate usage on my Vision, and can get close to 2 days with low usage. That's very typical for a modern smartphone. I usually get in the range of 2-3% battery drain per hour when the phone is idle. And that's with WiFi always on (even when not connected to a WiFi network) and auto sync of Gmail and HTC stock and weather apps. You haven't mentioned how long "overnight" is exactly, but I'll assume 8 hours or so. So your phone draining from 40% to dead overnight seems unusual. WiFi typically uses less battery then the cell data network, when WiFi is available. I suspect there is something else going on, besides just being on WiFi. If the cell reception is dodgey in your area (or fringe 3G reception), this might run the battery down (even if you are on WiFi) as the phone is constantly searching for signal. Or your radio may be mismatched to your custom ROM. Or you may just have a bad battery. Also, was the battery drain any different when you were on the stock or other custom ROMs? I personally haven't witnessed the battery drain to be significantly different across the ROMs I've tried. But that seems to vary, as there often seem to be people complaining about this or that ROM causing more battery drain.

The reason I thought it might be a hardware defect issue is that my wife and I got G2's at the same time. I rooted mine and have been running CM6.1.1 for a few months now, and my wife has kept hers stock. However, the battery issue hit both our phones at almost the exact same time.
It sounds ridiculous, but conspiracy theories are fun to play with. The fact that I've been rooted so long, and it JUST happened weirds me out. Add my wife's phone to the equation, and it's even weirder. I kept my phone on WiFi and 2G networks only last night (yeah, about 8 hours), and the exact same thing happened.
Maybe I should just get a new battery, I don't know. But I do religiously delete apps I don't use and make sure the ones I do use are syncing as minimally as possible.

Poor battery life

My brother has a desire which is running oxygen Rom but the battery life is terrible. It only lasts about 6 hours with the phone on standby.
I have swapped batteries with my phone but still same problem.
Any ideas?

settings then accounts and sync then untick the background data box, should help a little but generally battery life is quite poor

If i untick that, then push alerts on gmail wont work.
I will be doing the battery calibration as mentioned here,

This is not possible unless you're not turning off screen at all, having auto sync on and using navigation or something...

Change the Display settings to 20%. Do you have gsm or gprs? Maybe Your gprs reception itsnt good, try gsm

It's on gsm and the reception is very good at all times. I have changed to a newer radio as it was running an old version, ill see how it performs now.

Removing cellular from phone?

Hello all, I have been using the d2spr for quite some time... without mobile. I have no service on the phone and have no problems using it as an esspresso device like my p5113 tab 2. On my tab two there was a thread about removing the cell from the device, which I will more than likely have to look up again for that device. Is this possible for this phone? Anyone have any experience removing cell from the phone. I have read that searching for signal reduces the battery life, and I have yet to try it on the phone. If anyone can give me any pointers on this would be great. Also if you know which files to delete would save me a crap load of time searching for it.... thanks in advance...

are you basically trying to use it as a galaxy player? (i.e. an android version of an ipod touch?) if so, ive just put mine into airplane mode and turned wifi on manually. It greatly improves battery life as its not using the cell radio.

not exactly I use it as a voip phone and remote control as well as play various games, though there is no service on it, it shows the mobile connection. With the tablet it was a wifi only tab so removing cellular feature from android really increased battery life. Though I was not sure if it would work the same on the d2spr... not quite sure where to start though so thought I would ask, but thanks for the alternative, I am not sure about using airplane and wifi together as I have not tried that before.

gotcha. well, if youre using strictly voip, then the airplane mode and then turning wifi back on separately will work very well. like i said, ive done that with other devices and it substantially increases the battery life. Give it a whirl, what can it hurt?

Just an update with the steps on what I did.. as well as the results. With rooted device I deleted the 3 folders telecom, telephone, and another that starts with a tele that I can not think of. They are located in system/priv-app folder on root of system. (Using root explorer) After that I reboot, and all is working fine with no cellular at all. I have been letting it sit just to see how long the battery lasts on standby. So far I am at 28 and a half hours... I still get notifications and wifi works smooth. In the battery section in settings it currently reads charge remaining 8 days. Anyone with no service like me might want to give it a try... if something does not work all you have to do is re-flash what ever rom you had and that will put the folders back. and install cellular on the phone again... I would say that is the number one battery drain of the phone next to the display...

Day seven of my battery test and So far it appears that without cellular on the d2 you can get up to 10 days of standby charge. I did not use the phone at all for anything but to check status. Also, If you notice the small change in the curve, it is because it downloaded updates. It was connected to the internet the entire time...
