e61 in pocket - phone warm, battery drained - issue?

I got an e61 last week, and had an odd experience today... at work, I was carrying the phone in the pocket of my track jacket. The keypad was locked, and the phone shouldn't have been doing anything.

I took the phone out after a couple of hours to check the time, and noticed that the battery was almost dead, and the phone was extrememly warm to the touch. (I hesitate to say hot, but it was far warmer than even body temperature!)

Is there anything that the phone might have been doing to cause this? Is the battery at risk? This is certainly uncommon behavior -- I've never had a phone overheat while sitting locked in my pocket before!

Incidentally, I've carried the phone around in a jacket pocket without any trouble. This is the first time I've had it indoors at the office though.
 
Are you sure you didn't have it set to check for WILan (set it to never) and make sure it is set on "GSM" instead of "dual" in Network?
 
Does disabling the "show wlan availability" option actually turn off the wif network check? I have now set that to disabled. (It was the 10 min max before.)

It's already set to GSM only.

I'm more worried about the fact that the phone got so warm, than the battery life. Even if one of the volume buttons was being continually pressed in my pocket, the phone shouldn't be so warm...

And the phone has been searching for WLan's on its own for 10 min for about a week now, without getting hot. Unless the track jacket pocket trapped the heat?
 
I carry mine in my pants or jeans pockets all the time and it never heats up. I would take it to a nokia service center or send it off.
 
CLIFF NOTES

Story being, its not the phone, its something software based. The phone doesnt get warm for anything else than WLAN.



Long story

The phone gets warm when it is USING/CONNECTING to WLAN, and that drains the battery faster than a (insert prostitute comparison).

My guess is, you got SOMETHING like your email client, web client, whatever client, on a update schedule.

It might happen that the schedule came along and the phone tried to find the WLAN access point. You werent within range of it, so the phone kept the WLAN on, always trying to connect.

Searching and connecting are very different. Searching will only take a few seconds to look at whats around. Connecting will use as much energy as being connected.


I had that issue when my activesync had my router as connection point, and instead of doing "time out" when I was out of range, the application jammed into "connecting".

It killed my phone's battery in one evening. Sucked cause that caused my girlfriend to freak out on me because I didnt answer my phone or SMS (obviously because the phone was off and I didnt notice)
 
Hmm... I'm not sure that anything would have been running in the background, that would have been attempting to connect. Certainly being around the office, I had nothing really to connect to -- I see a free wifi spot, but have yet to be able to connect to that.

At any rate, I didn't have any problem last night. Today I'm carrying in my pants pocket, and so far, the phone isn't any warmer than might be expected from my body heat.

Thanks for the replies. I hope the wifi was all it was -- it makes sense, for emptying the batter, and perhaps the heat. And again, the track jacket pocket might be a relatively insulated space. In comparison, I've noticed the phone gets cold when sitting out during a meeting, or overnight; so it apparently conducts the surrounding temperature quite well.
 
Maybe you had a java application running in the background? It happened to me once, it was a game I believe, I was playing and wanted to minimize to continue later, so pressed 2 times menu key, got to stand by, and a few minutes later the phone started heating up fast, it was because the screen light wouldn't turn off, it was on like when you're using the phone. When I closed the game, it went back to normal.
 
my phone seems cool but today for some odd reason it felt like my leg and pocket was burning, but the phone was warm at best. yes, i do have wifi search on as well as gsm only. what could explain such an odd occurrence?
 
I have my email set to check every 15 minutes and usually keep contacts and messages, bluetooth, running through out the day. I'm usually ALWAYS on the phone from 9:30 am until 6:00 pm 5 days a week. (at least 30-40 incoming outgoing a day and many times more)...what else...tons of wifi surfing and gprs, stris, emailing texting....I mean basically I use this phone like a mofo and it has never heated up to the point where something was noticeable and I always just let it hang loose in my pocket. Not sure how multiple people are seeing this "over heat" problem but I'm not seeing it and it would be difficult for me to push the phone any harder.
