Have y'all tried charging the phone screen down? I've noticed that when I charge it that way my voltage was down for some reason. Also the battery stays cool. It's like the camera is a vent & my desk was keeping the heat in.

why does everyone try to find things to complain about? like i care your going to pull out your old outdated phone and use it? why is this even stickied? my phone is not overheating or having any problems and i got it on the release date, i would think if your phone is getting hot you would use common sense and take it back to sprint and they will replace it. people should realize that your basically carrying a mini computer in your pocket around on a daily basis and things will not always be perfect, and in the millions of devices that are made there will most definitely be some phones that have problems

The irony.

It's stickied because statements made by a company representative in the OP are alarming and the issue demands attention, so that those with defective phones know what's up and to return them.

Glad yours is working out for you, mine is as well (after replacement for a bad RF unit).

Otherwise - please remember to attack issues and not people, cheers, thanks.

In my opinion, it is always better to be in the know. Being armed with knowledge is always a good thing.

Yes, often problems can seem blown out of proportion because the people who are having them weigh in more heavily than those who do not. However, I am seeing very balanced opinions on the issue here in this thread and I think that it is serving as a good place for collecting data on the subject and analyzing it with the collective mind of concerned users.

This is a HTC Evo 3D and more over an Android COMMUNITY.

Many people come here to find solutions to their issues, and an alarming issue like this needs to be visible because we need to get to the root of it.

If you don't care about it, why even post in this thread?

so today i was getting atrocious battery life. i unplugged it from a full charge at 6:45am and by 8:30 it was at 50%. at this point i decided to charge the phone and do the calibration as follows:

charge while on til green, disconnect from charger
turn off phone, charge til green
turn on phone then turn off again fully
charge til green and then finally disconnect and power on.

after doing this though i noticed no change whatsoever. immediately upon disconnecting from the charger it dropped 3% then over the next 40 minutes it dropped another 21%.
thats when i decided to start playing with the settings.

where i work they have a network extender for verizon, sprint does not have any reception at my desk and hence i am forced to roam on this extender. because of this i believe that my phone's radio is working extra hard to maintain a connection with our failing extender (verified using my droid x) and try and search for sprint towers simultaneously. so one of the first things i disabled was data. after a half hour of disabling the data my battery had cooled almost 10 degrees celsius and the battery charge declination slowed down significantly. it is now 5 hours later and it only dropped another 25%.

granted disabling data is not an option in most scenarios but in my case it worked perfectly as the connection to the extender is too slow for data usage.

from my experience today i am lead to believe that the heat issue may be related to the radio and your reception. i am not sure how roaming may affect this but it seemed to only be a problem with data. i could still roam without 3G and was able to send and receive SMS messages fine.

any thoughts? am i crazy or is this a reasonable deduction?

Default Thanks for the tips, input, and possible solutions...

Personally I think all the information contributed to the members on this forum has been a great help in exploring the issue, and I appreciate the ideas, possible solutions, and troubleshooting tips. And thanks to you all for trying to solve it for our common good, and confirming there is not just one or two people out here with the problem.

I don't see "whiners" in here, but people trying to address a legitimate concern. It's very easy to send a phone back to Sprint and get a new one (as I did) but it doesn't address the original problem when there is one... and the new Evo 3D replacement I received happened to have all the same problems of my first one. I considered sending the second phone back, and just giving up on the Evo 3D, quietly walking away from it. But that only serves me, doesn't help me, and leaves others with the same issue unaware until it's possibly too late. So sending the phone back, in my case, didn't solve the issue. My hope was (and still is) one of my fellow 3D owners will have an answer, and Sprint/HTC will address the problem (if found to be a legitimate issue) and publicly acknowledge it.. which in great part will be from the users of this forum.

Back to a little technical info/testing:

Recently, when the battery dies I've been pulling it from the phone and charging it on a digital LiIon charger to see what results I get. I can confirm, when the battery is directly charged (not through the phone) with a digital LiIon/LiPo charger at 4200mv and .5C (850 ma per hour), it stays cool (ambient room temperature 21 degrees C) and takes a full capacity charge, with an ending voltage of 4200mv. For me, with the information I have so far, it confirms this battery shouldn't be charged with voltage higher than 4200mv (the charger won't allow it, and if I "trick" it into attempting to do so, alarm beeps sound and it discontinues charging). Please don't try it (you must use a special charger and have familiarity working directly with LiIon batteries)

I did with the Evo 4G when I first got it (not battery monitor app... not sure it was out at the time), but not nearly to the degree I did on the 3D because I never had the need to... it always showed 4200mv peak, so the voltage issue wasn't there and no heat symptoms, so I had no concerns. The 4G would hit 4200mv a little bit before full charge... say 90 to 95%... and stay there after reaching capacity until unplugged.

Why are we seeing high voltage without high temperature?

Do you have any opinions on the accuracy of those sensors?

I checked my wife's Evo 4g last night while charging, I only got to play with it for about 10 minutes but it got up to 39.4 C and voltage was at ~3.85v. The battery level was 16% when I was playing with it so I didn't get to see what happened as it neared a full charge.

I went to sleep early last night leaving WIFI on, mobile data off like the previous two weeks. Woke up in the middle of the night and noticed the phone next to me (using it as an alarm every morning) is close to frying when I try to check the time. There was only 14% battery left at 2am. I went to sleep around 11 with 90% of battery, when I wake up in the morning, I typically have close to 80% left. Note that I don't charge my phone at night and only charge it at work. I use Juice Plotter for the past two weeks and have been monitoring the usage closely. Typical temperature is around 25C idle/charging, 32C while on use and 35C when on WIFI. During 11pm to 2am last night, the temperature was at 45C. I checked the apps that was running at the time and couldn't figure out what could have caused it. Have anyone have an issue like this where the battery just went berserk and try to blow up?

Open the battery compartment and push gently on the battery. Does it feel solid, or squishy?

If firm, then it's something on the phone that is drawing a lot of current, which is causing a lot of heat. I don't know what, given what you said was on, off and normal. But it's not the battery.

If it's squishy/puffy, replace it ASAP.

You seem very knowledgeable on the subject so maybe you can help me understand why the cut off point for the 3VO would be 4200mv. Would the engineers not build in tolerance above the 4200mv stated capacity?

Ok - help me understand - the penny finally dropped that you mentioned plating.

You're saying that the higher voltage creates a state where either electroplating or reverse electroplating occurs.

I'm not clear that (reverse)electroplating has a thermal by-product. (I reverse electroplate things, but never bothered to check temp.)

Hmmm.

If I understood correctly, the capacity is nominally 3700 mV and 4200 mV is the upper tolerance.

If I understood correctly, the capacity is nominally 3700 mV and 4200 mV is the upper tolerance.
I didn't see the plating comment, so maybe I am missing something?

You understand the voltage rating correctly, at least from my perspective and experience. 4200mv would be the upper tolerance, and devices and/or chargers should have that regulation and limit built into them already, just as I am sure the 3D does. With the high voltage, there shouldn't be much heating once full charge is reached and there is little activity on the phone, because the battery has reached capacity and their is no real current flowing through it.

The voltage (and heating that seems associated with it) seems to effect the minority of phones (based on the polling here) so the regulated charging must be working properly on most devices, even though the voltage reads as high. As to the voltage readings being reported incorrectly by the phone, I think that it's something possible but with what I have available to work with (1 Evo 3D and it's battery) and voltage reading and charging tools, on my phone it appears to read correctly.

LiIon technology is so complicated I hate trying to dive too deep into it because it then goes beyond my experience and comfort to speak about, and I don't want to be making guesses. A LOT of engineering goes into LiIon batteries and the devices that run them, because of the great power of LiIon and the "control" necessary to charge them.

When Alkaline, NiMh and other older technologies stray outside of their voltage range, they stay pretty stable. LiIon and Lithium Polymer much less so. NOT that they are randomly dangerous or volatile, they just require more care. Normally we never think about it, because the phone takes care of everything for you and we don't give the battery a second thought. You can't simply plug a LiIon battery into a wall without a regulated charger, which in our case is mostly the phone. In RC applications I've seen what happens when batteries are used outside of the set range. Phone batteries AREN'T RC batteries but they use the same technology and require the same care... so when I see the voltage on my phones battery outside of that "set" range, it naturally makes me question why.

I am far from an expert on LiIon batteries or phone charging technology... I am not a chemist or engineer. I'm hoping to hear or get input from somebody who is. I just want my phone to work normally.

OK - well, here's the data sheet for the TI charging chip - from the 3vo schematic, it's a TPS65200YFFR.

Rated output charging voltage is 3.5 ~ 4.44 V and it's programmable.

Or for those that prefer to access it directly from TI - http://www.ti.com/lit/gpn/tps65200

I have also confirmed that the voltage readings are correct in a previous post.

And the TI doc that Early just linked to confirms that the voltage can go up to the values we're seeing.

So the next logical hypothesis is that 4.35V is not harmful to the battery, assuming that the battery does not heat up unreasonably. New Li-ion tech? This looked interesting:

Good find!

Makes me wonder about the validity of just slapping any battery you like in this new pup and expecting goodness.

That is a great find.... if it's a new technology, it's BRAND new and changes everything I've know about liIon. POSSIBLY the phone is putting out more voltage so the voltage the phone gets is a little higher and the voltage the battery is supposed to get is 4.2V... like the chargers put out 5+Volts, but they don't go directly to the battery.... phone reduces it before reaching the battery. The PHONE may be able to run on a higher voltage than 4.2, so it allows itself to take the higher voltage from the charger and uses it directly, so it's not feeding off the battery at a lower voltage. The higher "horsepower" the voltage gives to the phone may help it's processor run more efficiently or something..... like many computers that run at a faster processor speed when plugged into the wall, then step down when running on battery power.

You have me really curious now. For example on many laptop computers, when the charger is plugged in, the processor runs at it's "full capacity" and seems to get a higher voltage... but when switched to battery the processor drops to a reduced speed to handle the reduced voltage and/or current coming in from the battery and to not drain the battery so fast. I would think the phone and/or battery would have a "pass-through" on it... so when you are using it when it's plugged in, it's using power directly from the wall.... not pulling it from the battery and then constantly recharging it. But I don't know. I'm going to dive into your specs to see if anything sticks out. One thing I still don't understand is why the battery would receive a higher voltage when it WANTS to run at 4.2 or less... coming off a charge it's normally over 4200mv, but it drops FAST down to 4200mv.

Same patent, much better site. Shows filing date of July 2010. Pretty new. Is 1 year enough time for something like this to be production-ready?

It's DEEP reading, and I'm trying to get my head around it but it is complicated. It sounds as if it is using PWM (Pulse Width Modulation) Charging IN ADDITION to Linear charging AND Burst Charging, and supplies the varied voltage to the battery AND the Bus so the phone (apparently) can use a higher voltage than the battery can supply. With PWM you can send voltage pulses several hundred times a second, each one carrying a small amount of amperage. You can also keep the amount of pulses per second the same but increase the length of the pulses, allowing them to deliver more current or ramp up voltage for a longer period of time in the same amount of pulses, but each lasting longer. Get's confusing! If everything available on this chip is being used, it is very advanced and brand spanking new. RC Motor speed controls work on a very similar principle and are considered computers themselves... and cost $125 to $250.

If you can hit a battery with 100's of short higher pulses of voltage carrying low amperage, I can see how that would work... not enough amperage going through to damage it. I'm stuck on the linear part though... the continuous charge it's also capable of. A constant stream of higher current... with that if it were to be over 4.2 volts the same rules should still apply, but it sounds as if this chip is doing the PWM, the linear, bursts, and in addition has an "overflow" available if the voltage is going too high.

It would be great if this IS new cutting edge technology and (I hope) I'm reading it right, as it would indicate you can charge the battery at a higher voltage but not in the "traditional" way. It doesn't sound like heat should be a major side effect though and I don't believe it is as designed. So if the voltage IS supposed to be high (?) but not generate heat, that is a very good thing as it indicates all the phones are supposed to be getting that pulsed width modulation at the higher voltage... it's just the phones that are having the heating issues with it that have the problem. A certain number of unit failures out of "X" amount sold, due to the chip being so new of course there will be some units that don't work as designed... that's the case with most every kind of phone release with every carrier.

It's odd though... I've been trying to find other documents on this kind of charging... Linear/PWM/burst mix and they seem to say it's important to still not let the battery voltage exceed the 4200mv, but Voltage Bus can be 4530 mv.... is it possible he phone is reading the "voltage bus" and not the actual voltage of the battery?

A document I was looking at... it's not in the phone, but also explains the charging in a similar way that is still complicated, but a little easier to grasp on.

I believe you'll find those modes in the charging control chip as detailed in the datasheet, no conjecture required if the capability is there.

I'm beginning to doubt what that rep told you about this being a real issue.

Some units out of spec needing return, yes - endemic design flaw, I'm not thinking so.

I tend to agree... I doesn't appear to be a "widespread" problem, depending on how many people you consider to be a large amount (this would vary from person to person, but I'm sure within a company there is a threshold that has to be reached.

I found this interesting part of an article on another website. I can quote the site if you wish, but it may be a competing website:

"We received a call from an HTC spokesman, Keith Nowak, who told us that he talked to HTC's tech associates. Although they saw a couple of reports online, they have been unable to replicate the problem on any HTC EVO 3D devices to show any overheating issues. They have not been getting any customer complaints either. It does not seem to be a widespread issue."

The fact that they haven't been able to duplicate the problem when it appears others here have been able to OR it just occurs without their trying is a concern, BUT since it isn't a problem with all the phones and only some, they will have to get a hold of a phone with the problem to test it. Sprint has one of mine, so I would like to think either they or HTC will do some testing to verify it.... then fix it and not just say "Most Android phones run warm" and leave it at that. I know that, and most anybody who has owned one does too. Nature of the beast.

I'm sure there are many out there who think the "normal" heat is a problem with the phone (when I think everyone here has agreed it's just part of using a high powered phone) and are reporting the heat as an issue... but the heat wasn't an issue for me until it became excessive under little to no use conditions, in addition to the high voltage. So I continue to feel there is a problem with some of the phones, and I do hope it is looked into. Case closed? I guess only time will tell.

Please link the site you're quoting, that's only fair - we believe in fair.

I can understand them stating that there is no problem if they can't replicate it. I'd ask that you contact them so they can be alerted to the issue you personally experienced, and perhaps even track down your phone.

For those who we've helped that did have this problem will say that this exploration was worth it, and I'd agree.

Default Noticed it varies by location

New to the forum... forgive mistakes made in answering this post...

Originally made the switch from the Iphone 3Gs to the HTC EVO 4G... and pre-ordered the HTC EVO 3D... getting it on the 24th...

Hooked on HTC... even with the problems that all these crazy great smart phones have

I am using Battery Indicator as my App for these readings...

The heat and voltage did vary quite a bit during the course of the charging... both going up and down... and not necessarily together....

Home: (Not Much Heat Noticed from either)

Plugged into USB for my LapTop:
96.1*F
4.01V

Plugged into Wall:
97.5*F
4.243V

Office: (Noticed a Lot of Heat earlier this week)

Plugged into Wall:
(tbd - need to do this again on Monday for you guys)

Could have something to do with the wiring of the plug (house/office) you are using... Unfortunately, not all wiring is created equal...

Overall, I have noticed some heat... but it comes and goes...

Battery life is very good considering how many Apps and Things I do on this phone daily... I am a heavy user...

Welcome to the forums!

That looks like perfectly normal charging results so I'd say you're in good shape.

The 3vo is a great step up isn't it?

My EVO 3D doesn't get hot while charging (on the wall charger), but it does repeatedly get very hot when it has been in use for semi-prolonged periods of time (30 minutes - 1 hour). Everytime the phone get's up to 39C (103F) I have an alarm go off. After the alarm goes off I put the phone up to the vent of my air conditioner in order to cool it back down again to 31C (89F)...granted I'm near my home or car A/C!

I usually have my mobile network, GPS, a few applications, a few widgets, and a HTC live wallpaper running.

I will post a log of my phones charging habits later, but here is what my phone is currently reading: 91% charge, 37.5C (99.5F), 4293mV, 618mA...

Obviously I don't have a log of my phones charging and temperature habits but from your best guess-timate (technical jargon...haha) do you think my EVO 3D handset has a problem that deems it worthy of a replacement?

Thanks for your input ahead of time!

Mine gets a bit hot from time to time and also randomly reboots from time to time, possibly because of this. Hopefully we can get that fixed cause I <3 this phone!

They quoted you diirectly and used Chris' Phandroid graphics for their article. I'll check and see if HTC contacted us. It seems odd that they wouldn't have or that I'd not have heard.

Anyway, thanks for the link, and we're always ok with them (unless spam of course).

all,

you can search on the net for other handsets getting hot or so called "over heating".. it happens across all flavors of handsets.. even larger older legacy handsets, iphone, crackberry... the touch pro2 i used on sprint , the diamond, the mogul... all of those had reports of heating issues.

i just want to keep the playing field here level. i just dont think the evo is overheating.. its just thinner and people can feel the normal heat discharge more.

rant

EDIT: just skimmed that "article".. more like a blog.. and no official reports from HTC and i would not consider a employee at a store to represent "Sprint". the post takes the word of one tech at a sprint store?

this just looks how a simple interpretation form a customer is conveyed as gospel.. its hearsay. and the internet is one way to throw doubt and unproven data out there and then it suddenly becomes a "widespread" issue.

i still dont find it to be an issue. i have every radio on and my screen is set to timeout after 30 minutes. i have many background options running and i notice no overheating issues even during charging a near depleted battery. my personal opinion is its just the way the handset is designed. i dont think any software can alter this.. its a physical reason one feels more heat.

also, keeping the device in ones pocket pant is not good for your organs (microwaves) and with no air flow in your pant pocket shouldn't it overheat?

ever put a chocolate bar in your pocket and have it soften/melt?

I agree.

Thermal runaway is important and we've done our job bringing this to people's attention for the few cases where it happened.

This is a new charging technology for cell phones and other makers are trying different approaches as well with their new offerings. (Samsung's GS2 charging profile is different and the blogs are indicating Apple is going to change as well.)

The main thing was never heat alone - it was the charging voltage above 4.2 V and we have an answer for that.

We both said it on the first page of this thread: nothing to panic about.

I agree also with you that it's time to de-escalate. Thread unstuck.

Okay, I got hit by overheating this afternoon. I was using my EVO 3D with a Rocketfish car charger that produces higher amperage (2 amps, from memory), and using GPS and the Google Maps app to navigate. I did this for just a very few minutes (see the battery log below) and happened to pick up the phone and noticed it was very hot. The info on battery condition under my battery monitor said "overheating" where it usually says "good"! So I shut everything down, just turned the phone on briefly a couple of times while I traveled (I was on the road, and had a relative who is prone to be alarmed if she calls and I don't respond quickly while traveling). Now that I"m home and I can view the log, I see that my battery was WAY hotter than it should be. Relevant portion of the battery log is here:

2011/07/10|03:22:25 PM|-395mA|99%|4220mV|36.3C|0|0

2011/07/10|07:31:20 PM|-322mA|76%|3989mV|29.5C|1|0

I believe I plugged into the charger and turned on GPS about 3:50, unfortunately I don't know the exact time. I had two brief stops , but otherwise ran until shortly after the 4:22 reading of 61.6 degrees<!> When I shut down the phone and left it off as you can see, except for one brief power up, for about an hour and a half. I invite comment or analysis. I can post more of the log if desired. These readings were recorded by the "battery monitor" widget, version 1.7, produced by 3C in the Market.

That's actually quite common under those use conditions. My E4G routinely overheated when I needed GPS for a long trip and I was charging with a 1000mA charger.

Funny... The typical 500-800mA chargers can't keep up with the discharge when using Nav, but when you use a 1000mA+ charger, the phone overheats. Can't win

My E4G shuts off charging when it reaches some threshold. Which of course means that the Nav will eventually shut off the phone. So I would hold the phone over the AC vent for a couple of minutes. That does the trick.

I also had a SetCPU profile that would alert me when the phone went over 45C. 45 minutes of Navigation always triggered that.

Current limiting built into both phones restrict max current draw to about 1 ampere.

My Evo 3D got up to 110.6 F this afternoon and it had not been on a charger. I noticed the heat after the music player went nuts jumping from song to song and the sound sounded degraded. Not sure what would cause that. Should I be concerned?

I've had some issues with Google Music Beta on the 3vo jumping around a bit. Is that what you're using?

this whole topic has got me a bit paranoid about heating and whatnot...is it normal that my phone heats up quite a bit when i play certain games? when playing tap tap for about 15 mins earlier my battery went from like 28 C to like 35 C..it's probably normal but I stopped playing at that point to prevent it from getting hotter..but i really shouldnt worry about it unless it's higher than 40 C or what is the deal here?

Like the Evo or any superphone, some apps require more of the processor and that will cause heating. Not an issue.

It was the stock player but then I tried the Google player with the same results. I am sure I am being somewhat paranoid. I love the phone but I am worried about the 30 days going by and being stuck with a lemon.

Download "AndroSensor" from the market.
androsensor - Search Android Apps on AppBrain

Great app. Gives all that info (voltage/temp) and a boatload of other information from the sensors.
you can also take a data snapshot (text only) showing the status of the device (Paste in Excel for it to look right)
BATTERY STATUS:
Temperature: 82.6 F
Level: 72%
Voltage: 4.027 Volt
Status: Charging
Health: Good
Technology: Li-ion


___________________________
30 minutes later...

BATTERY STATUS:
Temperature: 87.8 F
Level: 94%
Voltage: 4.397 Volt
Status: Charging
Health: Good
Technology: Li-ion


___________________

really wondering how accurate the sensors are. I use Li-ion in my RC cars and never have a float above 4.285 to prevent puff the magic cell from rearing its ugly head. I can't imagine these are actually pushing to 4.4 since that can cause serious issues.

So how hot is to hot? I am a fairly light user but if I plug my phone into my truck stereo it heats up every time. I only use it to and from work and my ride is short, about 15 min. When I get home I check the temp using System Panel and its usually between 110F and 115F. I am going to try an new cable as well as the stock player or the google player start skipping all over the place after a few minutes.
