Some HTC ThunderBolt units have a hot battery, overheating an issue

Some HTC ThunderBolt units have a hot battery, overheating an issue
It's not a secret that the battery life of the HTC ThunderBolt is not the device's strong side, but now a few reports (including some guys mailing us) have emerged that some ThunderBolt units are plagued with a heating problem, i.e. the battery is getting really, really hot.

Of course, smartphones are powerful gadgets and it's not something unheard of people to have heating problems on their smart handsets, and yet some folks report that their HTC ThunderBolts are regularly overheating while standing idle, which is concerning indeed.

It's claimed that swapping the stock battery with an extended one doesn't solve the problem, and the same applies to the various battery saving tips that are widely available on the web. One lad even says that he went to Verizon, received a brand new HTC ThunderBolt and the same problem occurred after a few days of use.

We didn't experience any heat-related problems during our time with the HTC ThunderBolt, but it seems this issue is real and is plaguing some units of this powerful phone. As of now no cure is available, but if you have the same problem or have managed to overcome it, share your experience with the community - it doesn't hurt to know how many people actually experience it, and who knows - we, together, may even a find a way to sort it out.

I have to say that the power button is also faulty on some Thunderbolts. The button sinks into the body and becomes really hard to push. I already had to swap out one since it exhibited that problem (4 hours after buying it, too!). The 2nd one seems good for now.'s not even a month after release and this stuff is mass produced, so, we're bound to run into some problematic units.

I don't understand why companies have R&D departments? Why on earth can a company as big as Verizon & HTC have an EPIC FAIL like this in their hands? How do test their devices? You need a good Q&A department to make sure the phone will work as advertised. It's crazy that they can't test this device the way it should be, that way they can see these things & avoid all the PR mess that follows. BOTH companies should be held accountable for this unfortunate turn or events. Poor customers who waited to get this phone, all the hype & fanfare just to get a LEMON! Verizon is on a roll. They rip their customer off with bogus pricing as per the post that says they need to pay back the government 93 million & then drop untested devices. Sucks to be a Verizon customer right about now!!!

One of my friends is a tester for Verizon, and I can definitely say that he really doesn't test $hit on the phone. He typically gives me the new software and ask me for feedback. haha What a joke. That's why it doesn't suprise me when Verizon phone have error or some type of failure. Their testing department sucks. They are just worried on how cool they are for carrying a phone that isn't out yet. :)

Does your tester buddy confirm any new LTE devices coming for April or is that leaked news a joke!?

actually the manufacturer tests the devices. in this case, that would be HTC. your story is bullshit, and the only thing your friend is testing at VZW is bloatware, which is garbage anyways.

19. Super Android Evo unregistered

Dude you are so wrong. Verizon test the hardware on their system. HTC tests the phone & Verizon tests it on their system. You got to be an idiot if you think a phone will go on Verizon's system without them testing it. Wow how can you post such a comment!

ok, you are truly an idiot. Verizon tests compatibility with the phone and the network. they do not do quality control on the manufacturing process. that is HTC's job.

33. Super Android Evo unregistered

@ zuno gyakusatsu Yes but they also need to test how the phone works not just that it does. That is selling out Verizon as a bunch of idiots. It's quality control for their LTE network. Verizon needs to know that LTE needs a bigger battery. For it to be charges 3 times a day is crazy. You are the idiot my good sir! If Verizon can't be held to how a phone works on THEIR system then who is. I can't beleive I need to even write this to you!

LOL LMAO That sounds about right. It's the only explanation for such an EPIC FAIL! LOL It's like the cable guy asleep in his truck. Verizon tester sounds like a real easy job. LOL Maybe Verizon is only concentrating on how to steal from its customer or maybe the "can you hear me now" dork is the one testing the phones. LOL

Mr. Evo, your comments are in bad taste. First, R&D departments are expensive. Second, HTC is more responsible for the development of the device itself. As an Evo owner, which is produced by the same company that gave us the Thunderbolt, you would understand that. Verizon is responisble for the LTE network that powers the device, and that has worked exceptionally well in the markets that have access to it. Third, this is brand new technology. If the history of electronics has taught us anything, its that new tech always experiences issues. That its a battery issue, and not a software or OS issue, users should consider themselves lucky. If you rushed headfirst into new tech without even waiting for the first wave of reviews, to see what the bugs would be, then thats your own issue.

HTC is not perfect, but I bet Verizon put pressure on them to drop a phone not yet ready for LTE the way it should be. So I completely agree with my statement before & stand by it. BOTH companies are responsible for this fiasco! Verizon should be more responsible in testing their LTE devices. LTE drains the battery & Verizon should know that. It is unacceptable for this to even be an issue!!! Hot batteries can be a defect or can be from using the wrong size battery on a battery draining network as LTE is!

You clearly have no knowledge of the world. Every major company in the entire computer and electronics industry (and others such as automobile, medical, etc.) has had some sort of issue with a component in their product line. Look at laptop batteries as an example that is similar to this. First of all, batteries aren't made by HTC or Verizon. Secondly, all it takes is one day at a battery factory with one little piece that isn't properly sealed for example, and you have several hundred or thousand problematic batteries. In the scheme of things, this figure is low considering the volume of products (computers and phones) being sold daily (easily in the range of millions). So yes, there are some issues but these are normal, especially for a new product. You won't find all issues when you only test a few hundred phones before release.

@ sgogeta4 Yes you are right, but a hot battery due to an energy demanding LTE network or faulty battery? That in 2011 is unacceptable. Maybe back on 1996. What? Verizon test their LTE phones while they are plugged in? Well that doesn’t make too much sense. Look LTE is a good technology but you need a battery to handle it, Verizon should have asked for a bigger battery from the onset! That is clearly a Verizon mistake.

Why does it fall on Verizon to have to do the testing on a phone that is manufactured by a third party? Verizon is making an investment into this device too, don't forget. They spend the money (more money than Sprint, by the way) to fully test the network so that their promises actually hold up (who does that anymore?), they advertise the device, and they have to purchase the device from HTC in bunches, which is not cheap; somewhere in the $500 per device range. Multiply that by some 500,000 phones. Verizon doesnt have to test the device to ensure that it works; that is why they are paying for the phones.

@ TheFunnyMan Why wouldn't Verizon test the phones on their system. How can HTC do that from the other side of the world. Naturally Verizon has to do it. Who is responsible for this then. HTC gets an order from Verizon, HTC doesn't go to Verizon & say can we put a phone on this network. Verizon has to check what they order. What when you go to a restaurant you just eat your food, what if it has a hair, or a fingernail? You would never know because based on what you say you or Verizon doesn’t need to check to see if all is well.

Verizon is going to test how the phone runs on their network, yes. Does the 4G work? Check. Does the 3G work? Check. It is not Verizon's problem, nor is it their responsibility to make sure the battery, which comes from a seperate party away from Verizon and HTC, is adequate to run the device. You dont fire the server because your grilled salmon came out with metal shavings. You fire the chef.

31. Super Android Evo unregistered

Yes & you get a new grill also. Like I have been saying BOTH are a fault. Verizon sould know their network to warrant that a bigger battery is needed to have a phone work well in a LTE network. Verizon is not innocent in all of this. You need be fair and understand that both Verizon & HTC are at fault. It's plain & simple.

If the battery isnt allowed to be an issue, then what is? Or do you demand a perfect device? Because if you do, then wake up, moron. With everything you ask your smartphone to do, and i can almost guarantee that you ask your Evo to run Pandora, Google Navigation, get text messages and reply to an email at the same time, be happy that poor battery life is the only issue you have.

37. Super Android Evo unregistered

?!?! WHAT ARE YOU TALKING ABOUT ?!?! You sound like a moron. What is your point. I just said it's BOTH Verizon & HTC's fault. Are you kidding me!!!!

I would think that Verizon planned on the phone having such a small battery life. If you were happy with the battery life, would you buy a 2nd battery from them at $40 or $50? More money in their pockets

neither the sunken problem nor the heated battery is a problem on mine.

as for the guy above.... mr evo fan... what company are you on? sprint? EPIC FAIL. haha. go patrol teh web on your WP+FG+R whatever it is network that is snail pace. my thunderbolt has been 100% as advertised.

12. Super Android Evo unregistered

@ Rich At least I am not getting ripped off, check your bill. LOL I think that is the EPIC FAIL!!!!! LOL yes it's 100% until it happens to you! But for your sake let's hope it ok. How is your bill!!! lol I left Verizon because of the overage charges and the customer service. Sprint is #1 in customer service. " JD POWER" and their plans have no overage & are cheaper. Doesn't sound like an EPIC FAIL to me. While I save money Verizon sucks you soul!! lol Why pay more, I get great service & Sprint is a pleasure. LOL you are the EPIC FAIL.

43. Super Android Evo unregistered

Dude that is your come back to call me an EPIC IDIOT & a doosh. Really? Wow I must have struck a nerve. Did you wipe your tear when you were typing your come back. Did you find out you were getting robbed by Verizon? Nah your daddy pays your bill so you have no worries. LOL Just let the big boys talk about this topic & go play with your dolls or think about what it is like to kiss a girl. Wow you are a weak person. LOL let's see how many names you can call me now. Don't cry dry your eye. LOL

I'm having the same problem and thought it was normal. Definitely going to Verizon today.

I have had my thunderbolt for 2.5 weeks now, my phone works perfect. No heating issues as far as the battery. I go throughout the day without having to charge my phone twice.

@ Pajara....Are you doing any battery saving tricks or is it running stock?

34. Pajara unregistered

I am running the phone normal, other people that have issues probably are not using an app task manager or simply got a bad battery, manufacturing issues occur for every product but only a small percentage. I would doubt HTC and Verizon would launch a phone in which 100% of the stock had a bad battery.....

39. Rich unregistered

i too dont have a battery problem. i take mine off the charger at 8:30 and with medium use it needs to be charged around 10pm. with heavy use maybe 8:30-9. but i keep a charger at my desk at work, so i just pop it on for 30 min at lunch and then i have no problems with it at all. i will say that my friend rooted his thunderbolt. he then downloaded an app and makes the CPU run incredibly slow while the until is locked. he goes the entire day 8am - 11pm and still has half a battery left.
