Hi .. i have a T2 touch on T-Mobile and pretty much since i got the phone if i ever connect to the net for web browsing or stuff.. most of the time for no reason at all after a few mins the internet just drops out and i have to just wait a while (5 mins or so) b4 it suddenly springs back into life.....
All the while i have HSDPA showing as maybe 2 or 3 bars...
Anyone else getting similar problems on the t mobile network? anyone have any idea on what might be causing it please?
cheers
It is same with 3 network here in UK, I think this is a general mobile network problem and also noticed that at times data connection will go on for hours and hours with no disruptions and sometimes disconnection happens more often. Speeds also fluctuate but overall they are all better than used to be!

I have noticed about 5 times in the last 3 nights that my phone is telling me that it has a dead battery just after it has 2 bars left and me not using it at all. When i take the phone out of the case it came with i notice that it is extremely hot and the battery is dead. Is anyone else having this problem and if so does anyone know the solution.
My batter life on this phone last a couple hours at the max with minimal use. I think this is terrible and im also looking for a solution to that if there is one.
Thanks in advance.

Sounds like a program is running... like you are continuously streaming data for some reason?
Even when I'm in an area with no signal and my phone is "searching" for a signal (which kills the battery) most of the time I still get around 8 hours or so out of it and it does not get hot. If I'm in an area with a good signal and I use only the phone as a phone a few times I can easily get well over 16 hours out of it.
The only time my phone gets "warm" is when I'm talking for a long time or streaming data for a long period of time (like using Google Maps or streaming XM radio).
Check your taskbar to see what programs you have running.
I have the same problem with my Alltel Touch Pro. I haven't found a solution yet. I have a spare battery and even with two batteries can't get through an entire day with minimal usage!
I work in an office which is a level below ground in central Sydney so most of my work day I am out of reception.
Now I do venture into reception areas so every now and then so don't want to turn aeroplane mode on and off all the time.... So please don't suggest this.
With my previous phone (i8000) I didn't have such a drain on battery when out of reception all day from what I remember. I used to get really long standby times but I didn't use the screen anywhere near as much.
Now I know the phone will use more power in low reception areas because it needs to turn the sensitivity up to get clear signal. But the i9100 seems to drain much more than all my other phones I have used.
I am on stock I3 firmware with CT Root kernel. I have a high level of 44% Cell Standby with only being on for 6 hours (and out of reception for 3 of them) even though I have used the screen for 1 hour and that only shows 37% of usage. I don't remember it being this bad on H3 but to be honest I didn't really check for comparison of usage.
Is this normal? My old O2 phone on win mo used to go into a state of sleep for searching for reception when at work because it used to take a few minutes sometimes, after I got into reception zone, to realise I had reception. The i9100 seems to get it straight away which makes me think is it polling all the time I am at work and draining the battery more because it tries so hard?
Hope I made this clear.
So it appears like from research this high drain is fairly common on android devices when in no reception areas. I could understand why it would happen in low reception areas where the phone uses more power to pick up a weak signal. But why would the phone continually do this in a NO recpetion area. I thought samsung would have made the phone relaise it has no reception and only try every 5 minutes or so...
I never noticed this on my i8000 or any of my win mo phones before it. I assume they realsied there was no reception and stopped polling at full strength the whole time I was at work. This would have been indicated by the slight delay of leaving my bilding before getting messages sometimes where now its instant. But without the battery usage stats I can't compare.
I have tried to find an app that automatically puts the phone into aeroplane mode when NO signal for 30 minutes or something. And keep s turning aeroplane off every 5 or 10 minutes or so. But I have yet to find anything.
I realise there are programs that will use GPS and do it automatically but this is not ideal. I only want it to happen when I have no reception.
Any ideas of ways to fix this without me manually putting my phone into aeroplane mode when I'm in my office and remembering to take it back out when I know I should have reception? I don't want to use location based because this doesn't work when I go up one level.
Just bumping my ancient thread.
After an app that will recognised NO reception for long periods and automatically put flights mode on. Then turn flight mode off briefly every 5 minutes or so to check if reception is back.
In my office I have no reception but if I go up two levels I do. So time based automation does not suit nor does location based unless it knows what level I am on.
See above for the long story

Hi everyone,
I dunno whether this have been posted, but I have discovered that, on the latest firmware 2.1.1.a.0.6 unrooted, when the phone set to wcdma/3g only the battery last so long.
After a day (24hrs) of standby and few sms, it has dropped to 75%.
Before I was on 2g/ both with wcdma preferable, 100% to 0% in 12 hrs only without doing anything.
could someone please try to see if it works the same for you.
Nope
because of different hardware and different software, i think it could be that.
i have used (before i jumped to android 2.3) 3G and it goes down too fast. this is the first time im seeing someone using 3G and saying it lasts more..! i have no idea!
I had to try locking the phone to 3G only just to test this, and now the phone goes from 100% to 75% in 11 hours. Not much difference from 3G/2G. 2G only is much better for battery life.
If your battery is zapped within 12 hours, you have some other problem.
after 3days6hrs, there is still 20% of juice left. few sms and about 20minutes of voice call during that period
incredible.

The difference probably has to do with network coverage in your area. I think picking one protocol over the other and not having the phone check both bands save on battery.
In my area, there's plenty of 3G coverage, and setting to 3g only, on my MiniPro 2 has saved on battery.
I suspect if you're in a good 2g coverage area, with spotty or bad 3g, setting to 2g only is probably better.

Heya all.
I'd like to know is there some android application that can control my 2G/3G settings based on a rule (something like AutomateIt, which does not do that) so that it stops my phone from trying to connect to 3G network when signal is low or lost?
Let me explain - I go twice a week to a gym which is actually in the basement of a building, and my carrier's network is very weak there, mostly no signal at all.
During those 2hrs period I've noticed that my battery drainage is larger than when I'm in the reach of the network.
Since I know that cell phones tries to log-on to the network using maximum power, and that 3G uses more juice than 2G, I concluded that my phone is trying to reconnect to 3G network when it looses signal instead of doing nothing.
Now, I don't exactly know how phones in general behave when they loose signal alltogether (I think they go from 3G down to 2G and then should go into some passive, listening-only mode, waiting for the beacon from the cell tower), but I guess that in such cases it would be better for me to force the phone to go to 2G (and keep reconnecting/listening on 2G) and later on, when it detects 3G, switch back to it.
Unfortunatelly, AutomateIt does not have radio control and I can't use it like I do at night to turn off sync and data and turn it on in the morning.
Also it does not have a rule related to network signal strength/type/whatever.
I can't use some timer app that would simply turn on/off airplane mode during that period, because I might not go to the gym sometimes, or I might simply be late or leave the gym later, so I'd still have larger battery drainage, even for a short period of time.
Many words, but I hope everybody understands my problem.
Cheers.
OK is it possible that nobody knows the answer to this?
I know that 2g/3g autoswitching should do it's job but watching my power drainage I get the feeling that phone keeps trying to force 3g and that eats the battery.

Hello everyone!
My device is facing strange problem, I know it is normal behavior among smart devices to get hot by intense CPU load. But it normally happens when CPU usage is intense like graphic intense gaming and constant browsing/downloading.
I am using 2G/EDGE Telenor Network in Pakistan and even chatting with friends on different apps causing this problem after using the mobile more than 5 minutes it starts getting pretty hot and battery drain too very fast ( same as using graphic intense games for 5 minutes). On the other hand, when I use the same apps on wifi network mobile don't get hot that quick.
I have even changed different firmwares available to our region. But my problem is not getting solved. Can someone please tell me what can be causing this strange problem?
PS: Sorry for the bad English, I hope everyone understood my point. If not you can ask questions

a faulty battery may also cause heating unnecessarily! also try changing the battery!

Have you rooted and changed the governor? I know this is probably not the issue but I can relate somehow. My phone got very hot very quickly while on pegasusq for some reason. If not, I cant think why it would get hot. 2g/edge is supposed to be less cpu intensive than the alternatives.
Are you sure its the cpu? have you tested it by taking out the battery when the phone gets hot, and feeling if the battery is? if its not the battery, the bottom part of the phone will feel hot, then it is the cpu.

I don't think that battery is faulty. The phone gets hot only when I am on EDGE data connection. Other than that, the phone battery is doing pretty good when I am using wifi and it will go for more than a day or so.

No, I am not rooted, using pure stock firmware (I9300XXEMF6) and obviously using stock kernel. Yes, I am pretty sure its CPU because phone gets hot from bottom part (front and back) got hot when this happens. And if I constantly use EDGE for like half hour, the phone gets super hot then I have to put down the phone and lock the screen for 5 minutes then it starts doing well.
The problem only happens when data transfer is being in process when modem is receiving and sending signals. If I just enabled the EDGE data connection and don't use Internet then the phone don't get hot.
It looks more of a network problem, I have read the blog post about fast dormancy. I think this network problem has something to do with fast dormancy.

the phone obviously gets hot when using internet via data connection and that is common for many people.

Thanks but with all due respect, I am not new to smart devices and my previous phones didn't get hot on EDGE connection that quick (in like 5 minutes) on same area and same geographic region. I am facing this problem specifically on S3. Network sim signals are also doing fine (full signals). Now, I have left with only this option to disable the fast dormancy.
