If I remember correctly, I was using the new Onlive app for the temp in my OP (but it gets north of 125°F commonly on normal games). If you (or anyone else reading this) have that app, would you mind running it for few minutes & reporting back? It wouldn't surprise me if it played a role in tipping the temp over the edge (Onlive is a magical service // magic = power).

^^ Nice. This is what we all need to know. Can you do something fancy / intensive w/ your replacement phone for a few minutes and see if you can get it into bacon mode again? (gaming or streaming w/ 4G enabled, etc).

If we can confirm that "hot phone" is somehow a hardware issue, its warranty time. :cool:

I got a replacement that was an A revision and the thing got over 120 degrees after being on the charger for a few minutes... Good thing I noticed it or my battery would have probably been torched lol. Sending that joker back
[HTC Rezound] replica9000:
After your phone reaches a certain temp, it should stop charging. You'll see the LED blinking green and orange.
[HTC Rezound] platinumrims:
it did, it was flashing green and orange and idk how long it had been like that before I noticed it. Didn't warp my battery thank gawd. I sent that thing back and just got off the phone with them to get another one sent. I'd rather than a broken front cam then one that gets hot just from charging. What's aggravating is that they sent that phone to my old address that's about 2 hours away, so I had to drive basically 4 hours to get a busted phone. Not a happy camper. And apparently they left the thing on the porch too unsigned for.
[HTC Rezound] thatsricci:
yeah I haven't seen it go over 101F either.. i thought that was pretty hot too...

This happened when I was setting up my contacts and i linked 300~ some accounts at once, it cranked for a while and got real hot. yippiee.
[HTC Rezound] jim_0068:
My usual work day consists of exchange email account, two gmail accounts pushing, streaming A LOT of Pandora and Internet radio and checking greader and facebook often.

The above would overheat the phone above the charging threshold of I think 115* everyday. Now it barely gets to 100*. Same thing also happened with my extended battery as well.

Explained all this to Amazon rep, they rma'd it and the new one is fine. If your phone is getting that hot return it.
[HTC Rezound] Delldorado:
Haha nope keeping my original. Amazon said they'd pay verizon to do a battery test and replace it if that's the problem otherwise I get the peny sale until Jan 8th. Won't gimme another rezound but I love this thing.

Until then ill be putting a stove top background on the replacement and bring it to work with me so I can make lunch on the go

Sorry about the size. This was this morning and notice the battery at 80%. Ill just. Leave this here
[HTC Rezound] nrfitchett4:
anyone having temp problems, do you keep your phone in a case? Those gel cases are great at insulating the phone. I've seen 145 only when charging with an aftermarket usb cable. I'll try onlive on 4g, but I did 4g streaming on netflix to kill the initial battery charge and it never overheated.

Also, if the phone is plugged in and the backlight is set to max, I can see the phone getting pretty hot. None of these phones really have the space to properly dissipate heat.

---------- Post added at 08:29 PM ---------- Previous post was at 08:03 PM ----------

ok, did a little experiment.

Loaded up onlive, set up acct, streamed someone playing a game (not buying any games).

Set screen to max brightness, turned off wifi (so 4g on), and plugged into charger.

Let it run for 20minutes then checked battery temp. 117F. I'm guessing this is about max for my phone at max usage. Already down to 112F just by closing out onlive.

I know HTC has overheat issues, had it on 2 hd2's, so I'll keep an eye on it, but as long as its not locking up from overheating, I think my phone is ok.

heat problems solved

I have used HTC phones way back to the BlueAngel days. I tried others over the years, samsung, Iphone, ect. but have never had the satisfaction in build quality and function that you get with HTC. That being said, the newer phones seem to max out on heat easier mainly because they just DO more than the older ones did. The first thing I do when I get my hands on the Latest-greatest-newest devise on the market is buy an extended battery for it. To me, they seem to dissipate the excess heat much better. I know a lot of people like really slim phones so you really have to decide what kind of trade-off you are willing to make. Do you want a thicker phone with no heat issues and good battery life that you can use ALL the functions on or do you want that skinny little thing that dies in the middle of the day or overheats if you use it the way it is meant to be used?
[HTC Rezound] punman:
Do people who get bacon mode have 3.7V or 3.8V batteries? Curious, as I saw someone report they got one phone with one, and then another phone with the other. Might make a slight difference.

I don't have any heat problems, and have a 3.7V 1620mAh battery.
[HTC Rezound] dustintheweb:
I've got a 3.7 on my current bacon rezound, so no dice there. (Still haven't had a chance to replace it).

Something funny I noticed printed on the battery: "Do not expose to high temperature (140°F/60°C)" :rolleyes:
[HTC Rezound] nosympathy:
I am so confused. Last night I played Pokemon blue...yeah...lemme hear the remarks...a 23 old guy playing Pokemon blue. It was either that or actually watch sex and the city 2 with the girl. Anywho my battery never went above 95°F. Now that I spent 15 mins on my xda app alone I am at 111°…

Lol?

Squirtle saved you. If it were Pokemon Red, Charizard would have nuked that thing to 180°F easy.

Verizon's position is that the are no reports of these phones overheating.
[HTC Rezound] dustintheweb:
lol I know, they tried to tell me the same thing.
[HTC Rezound] Ullmz469:
I have seen 120F plus, So I went into verizon last night. The guy there tested the battery and said it was bad and ordered me a new battery. I'm skeptical on that the battery is bad. He told me the voltage was measuring 4.2v. The battery was charged about 71% and that time. Does that indicate the battery is bad or can the battery voltage vary from the 3.7-3.8v recommended voltage at times?
[HTC Rezound] jdmba:
Battery

Let me +1 the last post. I have found a really good verizon rep, who has put up with me swapping out 3 times. On swap # 2 after he looked at the phone, he said 'you know what, I think the phone is good, but the battery is bad'. He opened a new Rezound, used that battery, and my phone heated up so he swapped it. Ironically, he swapped it for THAT Rezound with THAT test battery, and that Rezound was actually worse.

My current Rezound may SAY it gets hot with Battery Indicator, but it doesn't feel hot, unlike my prior 3 phones. But the part that does get warm is definitely the center (Battery), and not the top or bottom.

I believe that we may, in fact, be seeing bad batteries rather than bad Rezounds. When you 4G or something that starts pulling juice, the battery would naturally start to heat. If this phone stays stable for me, I might just buy the extended battery and see what that does.

My 2 cents.
[HTC Rezound] shankville75:
My first Rezound got up to 118!! It would do it so much that when I took the battery cover off, the battery smelled charred. So when I took it to VZ, the Rep acted like he didn't believe me since he was the one that sold it to me in the first place. He turned on Youtube, minimal heat. He surfed the web, minimal heat. He recorded video in HD, it heated up a lil. He said that it was normal. Then I told him to take off the cover and smell the battery. Once he did that, he went straight to the back and returned with a new Rezound. I haven't had any overheating problems out of the new one and I stressed the hell out of it trying to heat it up.

Off topic and on a lighter note, I was watching Lion King with my daughter the other day while skimming through Tapatalk. The part where Timon was dancing the hula and teasing the hyenas to chase him came on. The lyrics went "Ahhhhrrre you achin, yup, yup, yup. Fooor some bacon, yup, yup, yup....I literaly ROFL'd :o

I probably will, what's strange is the battery indicator showed 131 degrees and 4.01 volts. I quit the app and rechecked it and it was at 109 and 3.86 volts. I read where these are 3.7, not sure if the voltage was too high.
[HTC Rezound] jdmba:

I am not entirely sure Battery Indicator is reporting correctly. On my Rezound # 4 (current) it says 100 when the phone is only slightly warm. My prior Rezounds would heat and you KNEW they were hot.

[HTC Rezound] jbh00jh:
I have had my Rezound since release and yesterday was the first time it heated up. I get a great 4G signal at work and home but yesterday I was in an area with a terrible signal. It went from 1X -3G -4G - 1X (etc.). When I was using Maps on 1X it heated up to 107 degrees. But when I got back in a good signal area the temp dropped back down to 86-88 degrees using maps. So it must be a low signal / battery issue. As long as I have a decent signal it dosn't heat up no matter what I am doing.

[HTC Rezound] jbh00jh:
At home on Wi-Fi temp is only 81.7.

The heating issue must be the antenna straining to get a weak signal and making the battery work harder.

I am wondering if the extended batteries ACTUALLY help with either of these (as the new back cover will have a new antenna; and the battery will have more juice).

I just got my Rezound today and it is a CLN replacement for my Charge. What app are you guys using to monitor temperatures?
[HTC Rezound] 1heffer:
Just got the extended battery today. Charged to 100% (took forever), and am now convinced that the original battery was defective. It was always hot when being used and life was abysmal. There's no way that the 70% bump in battery capacity could translate to the gains I'm seeing on my first charge. Will keep you posted.

Oh yeah,,, my highest battery temp was damn near hot enough to burn my finger on the battery door. I was worried about an explosion!
[HTC Rezound] HTC Rezound:
Been hitting the high 120's here with casual use. A concern is that it won't charge when its this hot. Does the extended battery fix the heat issues? Also how many hours of moderate-heavy use would you get out of the extended battery (never actually bougt one before)

"Battery monitor widget" is the app I use, it actually logs your temps at whatever interval you set, I have mine every 5 minutes, hottest my phone has been since the day after launch day is 121°F, one time and hasn't gone over 115° other than that, I have a tpu case on at all times.

You have to remember that ambient(outside) temperature also makes a difference. At 70° ambient temp your phone should never see 130° if it does return it. Now if its 95° where you are 130° isn't so bad.

Sent from my ADR6425LVW
[HTC Rezound] TB13:
Lithium Ion and lithium polymer batteries both have a minimum voltage of 3.7 volts per cell (fully discharged battery) and a max of 4.2 volts when the battery is hot off the charger. These batteries will stay at 4.2 volts while the device is on because of how lithium ion batteries work, they spend their mah or capacity then begin to drop in voltage. So with that said, your battery was fine.

For everyone having issues, the reason this happens is because of how crappy these batteries are. The stock battery is about 1600mah and most likely has a discharge rate that is very low. To figure out how much power the battery can supply you multiply the capacity and the discharge rate and find out exactly. For example if the battery had a discharge rate of 6c then you do 6 x 1600= 9600 which means the battery can supply a wimpy 9.6 maps. the more amps the battery can give the phone, the less load on the battery. When you try to play a game the phone demands more power and the battery goes into "shock" because I cannot supply the amperage to keep the phone running without heating up. The heating up happens as the battery tries to push out more volts power than it should and because lithium ion batteries are made of sheets of copper stacked up the battery heats up and over time puffs.

These phone company's need to get their S**t together and get some higher discharge batteries that can handle the load instead of taking the cheap route. These phones are much more power demanding then they used to be and this needs to be addressed.

Hmm... So, at what threshold are people looking at exchanging their devices / batteries? Just playing Angry Birds with some downloads on the background is pushing the the batt to 113-114 ( not to mention, drilling my battery life). The part i don't like is how easy it is to feel the heat. Of all my previous devices, it has never happened before. It can get up to 104 only by charging.

Also. Should i relock my device if i go on, or do they not really check for that?

Since the battery was running down, i threw it back on the charger... Playing ab while dling from dropbox pushed me to 125, and my charge light to start blinking........ Fudge me... Back to vz she is going.

I usually hover around 115 - 120 during heavy usage. I put my phone out in the cold when tethering to keep the temps down.
[HTC Rezound] Divine_Madcat:
I am sorry, but in no way should this be normal.. that kind of heat on a Li-on battery will kill it no time. My phone hit 125, and that is good enough to encourage me exchange it.

[HTC Rezound] feralicious:
I just got a reboot which could be somewhat due to heat.

Was using wifi tether to upload a 450mb file. Saw phone get to 43*C (109.4*F) according to WT.

Lost internet on my laptop, checked connection. Figured it was due to screen being off, I have power set to "normal" Don't know if that makes network turn off when screen is off or anything like that).

Also have CPU setting for when screen being off set at 192/596 (although now that I went in to check settings CPU Master showed my Screen Off profile unchecked... hm...).

So... then a few minutes later I check again and phone says it's at 46*C (114.8*). So I clicked on settings to see if I could change it to farenheit and phone went to reboot. Got stuck on boot animation for about 5 min before I pulled battery. Then... when I get it rebooted it gave me a low battery alert saying it was at 9%.

Wondering if that whole combination caused the reboot?

It always gets pretty warm/hot when I use wifi tether but I've never had it reboot before and never noticed it get higher than 43*C. I also never usually let my battery get that low.

Also had a case on it. It's just like the Verizon kickstand case but a knock off. And looking at it now I realize I can pull out the kickstand to aerate the battery a little if I think it might get a bit hot in the future. Or take it off, of course.
