Evo getting extremely hot!

Ever since I picked up the Evo, I have noticed that it is getting extremely hot after using it for a while. Usually happens during Wifi browsing or playing a game. Roughly 10-15 minutes. The kickstand gets so hot that it is almost untouchable.
Using battery monitor widget I can see that the phone temperature gets anywhere from 107 degrees Fahrenheit to 111 degrees Fahrenheit.
I have used several kernals from CFS, BFS, HAVS, NOHAVS, SBC, NONSBC and I am experiencing the same issue. Same thing with different ROMs.
It happens whether the phone is charging or not. I have noticed that it happens more quickly when charging.
Anybody know what temperature threshold the battery has before it begins to get damaged? Anybody have ideas to resolve this?

How is your battery life when the phone gets hot like that? bad, I would assume? Perhaps there is an app that is throttling your CPU 100%, causing the phone to overheat. Does this happen after a completely fresh install, after a full wipe? Have you tried a fresh install without adding any apps back, just to test and see if you get the same results? I'm not sure what the actual temperature is, but the phone has overheat protection. Once it gets to a certain temp, the led starts flashing orange and green. I've had my phone get in excess of 114 F, but that's while under heavy use. 4g tethering, streaming music at the same time, while charging. Under normal use, i'm usually around 80-98 degrees, somewhere in that range, depending on what I'm doing. It only goes over a hundred for me when I tether or play a game or something. What PRI are you on currently? Some phones don't like the newest 1.90 PRI, and dont run well with it (my phone being one of them). Using the 1.77pri works much better on my device.
I would try using Spare Parts, or OS Monitor, or maybe Watchdog, to try to see if anything is running away with your CPU.

Anything over 120 degrees is too hot, under that and you *should* be ok. A friend of mine has a new white one that is doing the same thing and the people at the sprint store told him the wifi and having the radios on will cause it.

hot HTC Evo
Mine seems to pick up a lot heat from receiving emails. Started about 6 months into the use of my new phone. Battery starting acted up as well. It does heat up when playing Pandora & Sirius, but it will heat up without radio use. Mostly just from updates and large emails. Very, very disappointing.

Maybe an defective motherboard ?

Yeah, as someone said a while ago, check to see if there is an app keeping your CPU at 100. There was a gps driver for aosp roms a while ago that caused CPU spiking. Happened to me and while it was spiked my phone was dangerously hot. Flashed a different driver and was back to norm temps. Good luck.

Monitoring phone temperature with extended battery?

So I finally bit the bullet and purchased two Galilio 2000mah batteries from ebay and currently have been quite pleased, however, I use the battery monitor widget found in the marketplace and I have found that it is not correctly displaying the temperature. It is always stuck at 77.3 F. Using stock battery I am able to get a accurate temperature.
I like to be able to get a temp reading so I can stop using the phone if it gets too hot.
Any ideas why this is happening and/or recommendation for one that will work?

BatteryTime Lite seems to report accurate temperatures for me and my Sprint OEM Extended battery.

I use battery left widget its dead on! It just takes awhile to calibrate but it works.. check it out!

Unfortunately, neither of these programs worked for me. They did the same thing as Battery Monitor Widget. Showing a constant 77.3 F. Any other ideas/suggestions?

Yep... cheap battery is cheap! I am betting it doesn't have a temp sensor....

I think a good app for estimated battery would be juiceplotter. Its in the market. I use that and its pretty accurate, but sometimes its off.

If battery monitor widget doesn't work... nothing is going to. They all get the measurements from the same place.

Yeah, I thought so, just was hoping for a different answer. Oh well, life will go on. Some how.

Same here, cheap '2000mah Galilio' batteries from eBay always read 25 deg Celsius.

You're going to be okay just by feeling the phone. If it gets hot to the touch, shut it off or take it out of your pocket. It's a waste of space having battery temperatures displayed if you ask me, unless you're way overclocked or running Snap.

Has anyone solved the "Low battery" and "immediate turn off" problem yet?

Has anyone solved the "Low battery" and "immediate turn off" problem yet?
Man this is the most frustrating issue EVER.
I'm running SRF 1.1.0
I have a 3500 mAh battery.
For some Farking reason, if the battery is under 50% and I get a call. It will RANDOMLY beep LOW BATTERY and turn off, in the middle of the farking call!!!
You turn it back on and it'll have 40+ % charge left!!!
AHHHHH!!!!!
After watching the 25 how to videos, I fixed almost everything that pissed me off, but this one thing drives me bonkers!!!!

I think that's the battery. Is its a yoo-bao from china (cheapie) or a good brand from a reputable source(sedio)? I have that problem with all the cheapies I bought on ebay.

It's not just the battery. My stock phone and rom does it too when the battery gets to 15%. When it reboots it has 20 or 30%.
This phone should never have been released with such a serious bug.

For "such a serious bug" it doesn't seem like many of us have it... I can keep a call all the way to 0%...did it a few minutes ago. Have you tried calibrating the battery stats?

Now I dont normally let my phone get down to 0% but yeah i know i've gone WAYYYYYYY past even 10% and the phone hasn't done this. Stock battery not extended.

it's a cheapy battery.
However, it's also a bug somewhere in some software...
If it hits 15% when u are NOT on a call, the phone doesn't shut off. It's only when you're actually talking that it does it.
I'm surprised to hear STOCK people saying it happens to them... When I had my phone stock it didn't do this. I assumed it was a ROM issue.

I would try calibrating... I believe there's an actual app in the market to do everything for you. I'm fairly certain its free, so ill post a link, but if its not, I apologize, and well get a mod to take it out.

Yes. I've calibrated my battery. I have seen a couple threads on the issue. I have repeated the issue on several roms and modems. Happens every time i'm on a call and the battery gets to 15%. That makes it serious since it is a phone after all. What if I was talking to 911?

What I'm hoping for is I can figure out what you guys are running that doesn't crash on you when the low battery beep happens.

I think this is a battery issue. I never had this problem with stock battery and it happened twice on cheap 3000 ma battery I bought. Returned the battery and got another one (same kind) and this one works fine. I think this is a manufacturing problem with cheap batteries. When you look at reviews of more expensive ones online, you never see anything about this problem.

I have found the solution! It turns out that our phones, much like a simple light bulb, just don't function when they don't have enough juice...
Since I can't modify a light bulb to magically require less power, the only solution I have found is to provide the specified power level. I have applied this same method to my phone - when the battery gets close to that magic threshold, all I do is - get ready for this - charge the phone again!
Seriously, though - everything takes power to operate, and a low battery can't put out the same current and voltage as a fully- or even half-charged battery. This isn't a bug, it's just a fact of life (with current technology, anyway). Who here complains when their almost-dead AA batteries can't power an Xbox 360 controller? Most of us just replace them with fresh ones (or charge them) and keep going.

This! Cheap batteries are never worth the money. I bought some cheap chinese rechargeable packs for my 360 controllers... they ALWAYS show low charge even if I just charged to full. Same deal with cheap chinese cell phone batteries.
I am sure the battery calibration is way off with one of the cheapies.

Ok Mr. Smarty pants. You are not understanding the problem. It happens with the stock battery too.
The SECOND you hit 15% while on the phone and get the battery low warning, the phone turns off, MID CALL. You turn the phone back on and it will last hours, even on the stock battery.
If it hits 15% without being on a call, it does not shut down.
That is the real problem here.

This has happened to me once , what could be the cause ? Defective phone or software?

You mean just like a 360 controller can have enough juice to turn on, but not enough to actually play? Or how a flashlight will be too dim to be worth it when the batteries get low?
Would it be better if the battery ran like a champ right up to the second that it shuts off without warning? That would fix your problem - no notification when the battery is low (the sudden shut off can't be avoided until we find an unlimited energy source small enough to fit in our phones)
Your expectations are unrealistic. Just sayin'...
Sent from my SPH-D700 using XDA App

J3ff, it's likely the cheap battery. Here's why:
Charge level is a simple linear voltage function. Our phones consider 4.2V to be full charge (100%), and empty to be around 3.6V (0%). The voltage drops roughly linearly between these two values as charge is consumed.
The kicker is this: The voltage seen at the battery terminals is also affected by the interaction between the internal resistance of the battery and the instantaneous load, or current draw. For electronics buffs, this is the classic V=IR, and what happens is that the voltage on the battery will drop by IR in addition to it's unloaded voltage level due to whatever the stored charge state is.
Good quality batteries have a very low internal resistance, and will not drop much voltage due to an increased load. Crappy batteries are just the opposite, and even though they do carry the charge storage (most of the time) advertised, they are only suitable for low load applications.
What's happening is you have a battery with a horribly high internal R. When you make a phone call, the load increases A LOT -- transmit power goes way up. This if why phones get hot when talking on them -- they really suck the juice.
As a consequence, because of the high resistance, voltage from the battery takes a nosedive. At an "idle" reading of 50% (3.9V, thereabouts) you're probably dropping more than 0.3V when the load goes up during a call, the phone panics, and shuts down to protect the battery (LiIon doesn't like to be discharged below 3.3V, and can be damaged).
When you reboot, the high load is gone, so the voltage shows higher again, reflecting the fact that there is truly still plenty of charge stored and available. The battery simply can't handle gulps, but only slow sipping.
High internal R is one of the most common reject reasons from mfgs, and those batts are sold on the cheap to dealers and distributors in a secondary market. Honest ones then resell into appropriate application spaces where low-current is all that is needed. Most, however, are not that scrupulous, and sell right back to the same market, leaving behind puzzled and unhappy customers.

Critical battery temperature

Hey. Does someone you know, what is the highest (read: critical) battery and HW temperature in this phone? I am a little bit scared when I'm getting even 55*C on battery when I am using it as a navigation connected to charger in a car. I know it's too high because when it's heating over 49*C it stops charging. My question is how dangerous is such high temperature for HW and Battery? Is it normal behavior?

I never had such high temperatures, and I live on a hot country (Brazil). Try to check apps running in background, or, if you are using 3G and charger, it can get really hot. But I think it's normal, since my phone reaches 45ºC while charging, and I don't use 3G.

with 3g my phone gets crazy hot. i once left it on overnight (it didnt go to sleep) and when i woke up it felt dangerously hot, musta been 50deg or something
otherwise, with wifi it just gets warm... still worrying though, considering none of my other portable devices have ever gotten this hot before... just shows where all of the battery life goes to! :S
i dont think its the battery getting hot though, it must be the cell chip. my batt temps are usually pretty low, and the batt itself doesnt seem to get hot. its just the panel above the battery that warms up

My phone got so high temperature (55*C) when I was using navigation. Moreover it was pluged to the car charger (but wasn't charging because of high temperature) and mounted to the window in hot sunny day. And I'd like to know how dangerous is such high temp. for the device.

I wonder if we have dud phones? my battery life sucks ass... bare able on wifi, but **** with 3g

Agree with scott. With prolonged use my battery doesnt heat up, just the panel above the battery (where the camera is)
And my battery life sucks too. Gotta keep it charged in the car for even short (30 min) trips with navigation

Try checking the manual (if there is) for operating temperatures etc.
I'm not exactly sure of how it'll affect the phone but it poses health problems due to higher radiations.
Try preventing this by ensuring all other (running) apps that you don't need are closed by using a task killer and all connectivity stuffs (eg. bluetooth, data sync) ESPECIALLY THE BACKGROUND DATA if you don't need it. Also, if possible try to refrain from covering the back panel (mainly the area near the camera) and allow ventilation to let it cool so it won't overheat.
What else I do is leaving the keyboard opened so there's even more surface area for it to cool.
The problem isn't just about damage, but that you don't want to be holding hot metal.
Yes it sucks but its a price to pay for such high specs packed in such a tiny casing.
My friend who owns Samsung Galaxy II has his phone heating up even more frequently and quickly, so we're not the only ones

Its annoying because we know its avoidable and shouldnt have been allowed in the final design by motorola

I've never seen such high temperatures with my M 2.
Highest was 47ºC while charging and playing a game. It usually sits around 35-36ºC idle, and 40-42º during games.

That's normal guys... Every device dying in a "few minutes" with 3G. And U know what? From my last 3 devices which I have been using to surf in the Internet with 3G (Moto RIZR Z8, Nokia N86, Moto Milestone 2), MM2 lasts the longest.

That's right, but every app just showing the battery temperature

Damn..
Yesterday my milestone 2 became hotter as ever, just above the battery (where the camera is, like newbietown). First I turned it off, but it stayed hot even then. After I removed the battery it became cool again.
But! Now my MS2 is completely dead...
It's really not turning on again, and charging is really weird (irregular flashin led). And my warranty is void because of me installing argen2stone I guess ..

Well, just flash a stock rom and they'll never know...

My phone is not recognized on my computer using USB . Can I still use rsd lite?

First get to bootloader mode: Power + Volume Up (or down) + Camera
If battery is too low you'll need to buy a relacement or a external charger.

Try taking it to warranty. Argen2Stone is so lightly modded, maybe they won't mind it. Anyway, you have nothing to lose now. And this really looks like a HW problem, not SW
Sent from my A953

Beginning of next week I will hand it in for warranty. I think it has something to do with the power circuit in the phone. Sometime i've used HTC chargers (1A) instead of the motorola charger (0,85A).. That could be the cause Hopefully they cannot see that.

I don't think that's a problem. I always use a Nokia charger, I find the original charger too short, the Nokia has a good lenght. And I never had problems with overheating. Also, 1A is the maximum current that the charger can provide, not the nominal [email protected] anytime

R800x 2.3.3. battery life absolutely deathly

Okay so I posted here a week or so ago about how my Xperia Play was epicly failing....it was force closing everything and dying in just hours.
So I factory reset and used Titanium to restore all of my apps and stuff...and so far the crawling speed/force closing has for the most part abated (opening up texts and contacts still sometimes takes forever or force closes)
but the battery issue remains. My battery is absolute garbage at the moment. It drains by 10 percent per half hour if being used or even more!! And it gets hot constantly, and obviously at that time it really sheds the power and dies quickly.
If I'm CHARGING the phone WHILE using it heavily, it WON'T power ABOVE the % it started at!! It stays constant or goes down!!
I'm not sure what to do. Should I let the phone die, keep it off, and charge it while off till its 100%?
Or maybe my phone is approaching the situation it was a week ago...I constantly check the running apps and its the usual suspects, nothing crazy. I had to delete official facebook app because it almost ALWAYS lagged and oftentimes force closed.
It says cell standby is using 40%, wi-fi using about 22%, voice calls 17%, phone idle 15%, and dialer 14%
What happened to my phone? Why is it such a clusterf*ck lately? Any ideas/advice?

Are you leaving wifi on because that will really suck the battery down? Also do you live in an area with bad signal? Put it in airplane mode and see if the battery still discharges as fast.

My r800x dies in 6 hours whether it's on airplane mode or not. I've re calibrated the battery like 5 times so far, and it just won't get better. I'm regretting moving to verizon to this. I should just get a sim card and go back to my HTC Inspire. I can leave the r800x in idle with the screen off, while in airplane mode and it will still die in 6 hours. It doesn't even last a whole day of work. Mine's also rooted. I need some serious help with this phone.

Turn off wifi.
If you have it on it will search for wifi networks all of the time (unless you're home and connected to your own wifi) and it will suck your battery dry.

I don't even use wifi. I don't have access to the router at home, and my data is turned off when I'm not using it.

Perhaps you have a bad battery? Maybe replacing that will solve the issue.

It could be. Every time I try to check my battery's health, no matter what app I use, or even if I do it from the service menu it reads at "unknown". One app says that my phone doesn't even have a battery stat service, or something along those lines. I was considering just buying one of those mugen batteries for my phone, considering that I brought the issue to verizon's attention, and they told me they were gonna send me a replacement battery, but I never got it. This was all about 2 months ago though.

wow, sounds bad. mine will last all day, its an r800x on 2.3.3 as well but i can use it like normal, play about a hour of games on it, talk on it a lot, use wifi and 3g and do some average surfing and it will last at least 24-30 hours...
i'm thinking it must be a bad battery as well

Im running 2.3.3 verizon from the FTF and my r800x would last almost 3days, and thats with texting/talking/surfing using 3g and playing a shyt load of sonic . I would replace the battery with a genuine Sony replacement, dont ever buy a ebay knock off ! Furthermore, I don't believe apps that check your battery health are accurate at all, so dont waste your time.
Best way to check (imo) - Before you charge it up, let it go to 0% and die. Boot recovery and wipe the battery stats, turn the phone on and charge to full. After its fully charged, let it sit 10-15 mins on charge. Then pull of the charge and use normally, if it still dies fast, replace the battery.
If this idea was already posted sorry for double post

I swapped mine out for similar issues. The replacement doesn't have the same issues yet but I haven't put a single app on it. I can't say that adding apps caused it before because I remember it similarly not getting anywhere when charging while using. I also experienced it dropping while charging but it turned out to be a that the MTP device wasn't starting on the PC so it showed as plugged in and charging even though it wasn't (check the Device Manager). My Alienware M11x actually supports charging devices off that particular USB port when it is turned off so it was a bit hard to figure out when it seemed to charge some times and not others.

So I got a new battery. Battery life oz still terrible, phone still can't detect battery health.
Not sure why, but my battery voltages are higher than 3.6 :/

Hate to tell you but it sounds like your Play is defective.
The only way it would always get hot like that is if it was always running, that would be mainly driven by being in a REALLY bad service area that its always searching. I have a boatload of games etc on mine and my battery life varies from 2 days to 3/4 of a day depending where I am. Heck my battery life varies as to whether I leave my phone on my desk at work or on the shelf above me (lasts longer on the shelf).
But the fact you said that even in airplane mode it eats the battery, and a new battery didn't do the trick. I would say you got a bad one. Still under warranty I hope?

i'm not entirely sure. I got mine through verizon in august or september of this year. Not sure if Verizon would handle replacing it, since I didn't buy their extended warranty. I read somewhere that SE themselves can handle it since it's not a year old yet, but my phone is kinda required for work.
