Is overheating common? - HTC Rezound

I've done a few searches on the subject and it seems some people have the overheating issue, but not many (or its not discussed anymore).
I've had the Rezound for about a week now. It was a certified like new warranty replacement for my Thunderbolt. I have the extended battery.
I can't use the phone for more than 10-15 (sometimes more) minutes without it overheating (50° + C / 120° + F). This is normally just phone calls or twitter/internet browsing. If I play any game it's overheating every time and quickly. I'm rooted, unlocked, on just the stock ROM.
I'm curious if this is a common issue or if I possibly was provided a defective device. Would a custom ROM help?
Any insight would be much appreciated!

i would get a replacement asap

Lol aight, I take it is not that common. Thanks.

She runs warm, but 15 min with the extended battery sounds like a lemon. There have been multiple reports of extreme heat like that where people have traded in and no longer had the problem. Go grab a new one and see if you have better luck.

Is it gb or ics?

Had to return my first unit because its USB and/or charging system fried seemingly; it got to 130+ running heavy gaming and went 140+ overnight once on charger shortly before then.
Return it. My current unit tends to heat fast, but I run it hard too. But it only gets to 110-120 under heavy use, not running higher than 120 easily by any means. It is rather good at staying at that threshold or lower.

Thanks for the responses!

Oh, and GB for the one who asked.

I used setcpu to save battery and reduce heat
But now with cr gb rom its all good

I wonder if it's the battery...
I was at 7% battery. Been on charger 2.5 hours, only at 52%. Extended battery...
Or is my phone just eff'd?
Sent from my Rezoundizzle

i remember when changing and doing something its getting hotter so i duno

I would just get a replacment man. It could just be faulty. The newer versions of the rezound are supposed to be better then the older ones. Mine is a pre release unit, and works fine but I had experienced some overheating when I flashed a sense 4 rom, and many others didn't.

Amaze is a power hog and other issues

So, I made a switch from HD2 running android to Amaze hoping it will have a better battery life coz of its juicy more 1730mAh battery, more power efficient s-lcd screen and the fact its an native android device (which the hd2 wasn't) but its been barely 2 days and I'm seriously disappointed with it.
I'm have a moderate usage which includes calls, pandora, youtube and net surfing but it barely lasts till evening and the usage is actually less than what i did on HD2 coz I don't have put any games on Amaze yet. I had lots on HD2. With HD2 I could easily pass through the day and still have about 10-20% battery left at night and this was on its anemic 1230mAh battery
I do realize the HD2 was rooted and was running CM7 and had all kinds of custom kernels and stuff. So is stock Sense and HTC kernel the culprit here ?
I've already ticked in the setting for Power efficiency under power settings which turns off auto sync (I have google and facebook sync same as I had on HD2) and using auto brightness with the least setting, but neither of them are helping
One thing I noticed in current widget log and current widget display, is the power drain in standby hardly goes below 100mA anytime ? According to me, this seems to be the issue hogging the battery as on HD2 it used to be <10mA most of the times with occasional spikes...but in Amaze every value is like more than 100mA. Does the faux kernel and custom ROMS helps with this, a lot ?
Ideally I should try it myself and see, but don't want to unlock the bootloader and stuff just yet as if the things are going to be like this, I may as well sell it and put in some more money and switch to other side (sgs2)
The other theory I have is the CPU on HD2 is single core 1GHZ while Amaze is dual core 1.5ghz. Gingerbread doesn't have proper dual core support so things will improve when ICS comes ?
Also on a side note, is there a problem with earphones having L shaped jack on Amaze ? My primary headphones monster turbine pro which have L shaped jack don't have a very good fit in it and small amount of force seems to disconnect the headset from phone. Its really annoying, although my other earphones which have a straight pin don't have this issue. But its not the earphone problem either as I don't have this issue with turbine's in my mp3 player and HD2 ?
The stock battery was horrific for me so I bought the Anker 1900mah battery from ebay and It's far better than stock...I'm at 15 hours with 47% left...Tasker is helping a lil also.
Sent from my HTC_Amaze_4G using XDA
Hmmm didn't think i would have to upgrade the battery just after buying it, although seems something wrong is with the battery though...maybe HTC just bloated its spec to 1730
Yea, I have advanced task manager with auto-kill, but its really the same with it or without..

Try letting the battery discharge completely until phone turns off, and then plug it up and let it charge to 100% without unplugging it.
My stock battery last 12-16hrs depending on use. I also have an Anker 1900mAH last a good 18-20 if I charge it inside the phone. If I charge it with the Anker charger it last about 8hrs.
Guys what about the current widget numbers ? Have anyone of you got it or can get it to see how is the drain like for you guys?
No matter how strong the battery, if its going to [email protected], it won't last very long. 18-19 hrs on after market 1900mAh battery isn't very impressive figure either
I'm not quite sure of this drain, is the fast 4g on Amaze the culprit just like LTE
Also let me know if you guys have stock or custom ROM ?

i assume youre talking about cell standby? you WANT this number to be high on the list
You should use a battery saving app like juice defender or battery fu.
Personally, I use battery fu and I have gotten more than 20 hours of battery, on stock battery, running on stock phone, unrooted.
Sent from my HTC_Amaze_4G using XDA
I havent had any battery life issues with mine. Before rooting I could go the whole day on a charge but it would be close to dead around 10PM. I'm still getting used to the new ROM I flashed but battery life has definitely improved.
I would recommend opening the task manager and killing off some unneeded apps.

Using task managers to kill an app that you don't want running isn't bad, I think its the continuely killing all apps every 30 minutes that makes it worse.

I'm not sure why this should be high
It should be low ? A high number would mean its losing more power during standby...
Guys, There are 2 school of thoughts about task manager...I agree task manager may consume more battery if you look into the theory how android works...but I've tried with and without task manager it doesn't make much of a difference from what I observed
Also what about L shaped jack earphone issue? Is it fine for everyone else?
I have the same issue my battery lasts 6-8 hours MAX with intermediate use....juice defender, tried every rom and different kernels.
My brother Easily gets 16-18 hours with intermediate use (galaxy s2) same processor. I know his battery is a little bigger but I didn't think his battery life would triple mine -__-

Hi Glacier,
Thanks for the update That seems reassuring...
I've been researching on Amaze battery quite a lot, I think current widget numbers are misleading because even in Airport mode it shows more than 100mAh drain, which is not possible..
I've found out another app...My battery drain analyzer written by a fellow member here at XDA
https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain
It basically calculates the drain rate in %/hr, basically measures how much time does it take for battery to take 1% dip...
I've found for my amaze its close to 1.6-3%/Hr when in standby, when phone is not woken up during the period...I think its on a higher side but acceptable still...Can any member with a custom ROM/kernel also report his/her number..
BTW I've seen the numbers on TMO SGSII in their forum, this number is roughly the same there too ~ 2%/per hour for most users...

Heat and Battery

Amazing. Just when I've got enough stuff turned off that the phone is only ten or fifteen degrees above room temp, it turns out that it's not charging anyway.
Right now the only way my phone will charge is if I turn it off.
Maybe this is because I took the leak and went back to GB. I was convinced that all the power being lost to heat was the reason it wouldn't charge. Now, not so much.
I have pretty much everything turned off, and the phone's not actually using any juice. But it still isn't taking power unless I actually shut the device off.
The next leak can't get here soon enough. And I wish I meant that in a much better way.
Right now I'm glad I'm not one of those people who remembers every day of their life. Because I can't wait to forget the day I ruined my perfectly good Rezound with that leak.

Maybe it's just a bad phone ? Sure alot of people seem to be having some heat and battery issues, but just as many do not. There are so many variables between phones, unfortunately you probably got a borderline phone which can't tolerate the new software .
It sounds like you have a lot more issues than the leak is causing. The battery life complaint I could see. I've upgraded thirty phones and had two that had a decrease in battery life and this seems to be about normal for what I see on the forums. But the charging issue, that's a different story. I don't think the next leak is going to repair that any more than flashing the leaked RUU again would, but that might be what your phone needs.
It sounds like you think the leaked firmware has mucked up your charging.
What voltage/battery are you using?
Do you have another around that you can test?
When it is charging does it say USB or AC?
It might be better in the long run to see if Vzw will give you a refurb.
I have the big HTC battery, about 2.8 Amps. When charging, it always says USB, even when the USB is plugged into a wall adapter.
And yes, I didn't have these problems when I ran the GB release, but I also know that restoring my GB apparently did not restore all files. For example, I had to replace my WiFi module from another package in order to get rid of the WiFi error.
If you are within warranty I would call up HTC parts and accessories and explain your charging issue. I think they will be willing to send you a replacement battery to see if it fixes your issue. Some or many have had issues with the 3.8v batteries, when I rma'd mine they sent me a 3.7v. It is relatively quick and painless.... unlike sending it to PCD repair.
*hmm maybe you consider the "big HTC battery" the extended battery; my extended is 3.7v and stock replacement is 3.7v for reference.

Running stock ? Otherwise it would be smarter to run a replacement on stock for a week or so to verify the hardware is working properly.seems like a lot of quality issues with the resound that is being blamed on the leaks without making sure its a good phone to start with.

Sent from my ADR6425LVW using xda premium
hopefully you wont have a problem exchanging your phone

What should I check to find out what is using so much power.

I'm currently getting ridiculous battery drains(like 500 to 980 ma) when my phone isn't plugged in. My phone also gets really hot. This isn't constant but has happed a lot even right after restarting my phone. I have been using Battery Monitor Widget. It might be off or wrong readings but the heat and the speed my battery is draining tell me it isn't.
Details
3.7 volt battery
Drain of 500-900ma when only using 4g no apps open
Clean rom 4.3
Battery usage general show most battery is from display.
Sometime even when it plugged in to a htc usb charger it still has shown around -143 ma.
Any ideas
I'm pretty sure just having 4g on entitles your phone to half of its natural battery life XD
Typically a lot of drain comes from disturbance of deep sleep, I believe there's "wakelock" or something similar on the android market that helps prevent and/or shows what is causing it.
Of course, common issue, hard to say if it isn't something more generic
currently I have it sitting here charging with screen on only as far as I can tell. It for about 10 minutes was telling me it was charging at 32 ma then it went up 205 ma and bounced between that and 105 ma for a bout ten minutes. It went from room tempature to 44.7 degrees celsius.
Now it skipped to -55 ma (while still ac charging) for a few minutes spiked to +653 ma and now is back to 100 ma. That seem to be all over the place and the phone is very warm.
To me that indicates either a problem or a huge drain of power.
Am I just that far off. Has anybody looked at the reading from battery monitor widget or something similair to see what a normal drain is in ma or a normal charge.
maybe an unruley app running in the background? check what's using your battery: settings- > about phone- >battery- > battery use.
It usually shows the majority of the power (50% at least) going to the screen and not much else notable.
Also on a probably unconnected note it produces ridiculous RF interference. But only when charging. At work it was causing crackling in both my desk phone and laptop and when in my dorm it was causing loud cracking in my speakers well over 2 feet away. Is that normal for everyone else.
Start uninstalling or freezing apps that you've installed

This is also my problem. I have been experiencing huge power drain ever since installing the 3.11.605.22 leak. I tried different kernels, rolling back to GB. Went S-off and tried different radios, and then most recently moved up to the new 3.13.605.7 leak, and am currently on CleanROM DE 1.3 and nothing has improved.
Sometimes my mA will go beyond -1000!
Would appreciate any suggestions as I have no clue what to do about it.
I would suggest downloading System Panel from playstore. It shows you what's running and how much power its using from your device.

Copy everything off both cards, format both cards through the phone, internal and external, and then copy everything back.

That didn't do it. Down 12% in an hour with limited use.
Say, anyone else who is getting decent battery times have Battery Monitor Widget and are willing to give us battery-challenged folks an idea for what a typical mA draw range is for your device when you are using it?
I am having the same problem with my phone.. Its gotten a little better since moving to the latest Clean Rom, but if Im actually using the phone (screen on and doing something) the battery plumits. any suggestions would be greatly appreciated.
I bought this phone from someone and didnt get it from Verizon so Im SOL as far as getting them to replace it.

Low battery life!

My rezound is rooted. I am on clean rom 4.5 with the 3.13 kernel. Everything runs very smoothly and just how I like it.
I also have the OEM HTC extended battery in my phone and my battery life is still bad. It doesn't get through a day.
Am I missing something here? Maybe a bad setup? Any suggestions? Comments will be greatly appreciated!

How much are you using it? The screen seems to be a big drain on our Rezound.
I'm at 55% 12 hours into the day with the stock battery. Usage has only been a few calls, some FB, Tapatalk, google finance checks and several times into gmail but WiFi has been on all day except when driving for about 1hr (with 3g and bluetooth turned on).

As jazzy said 4g is really hard on the battery too. Google 'Extremetech 4g' to read their article to understand why. It's more to do with how 4g networks are configured than with the actual phones.

I actually was underclocked to 540mhz because I don't need 1.5ghz to browse the web. That test was mainly to prove good battery life is possible if you really need it sometimes. Todays results week be more real world use. I never run my phone like that. But I know I will still get good battery life with higher clock,4g, and bright screen

I think you're right about that.
Last Friday, I switched from the setup in my sig to the newer innefilibis v1.0 ICS ROM & my battery life seems to have dropped quite noticebly. I set up the new ROM with the EXACT same apps etc as the old one to get a fair comparison.
I do a lot of audio streaming at work which is really hard on battery life, but with the 2750 extended battery I do make it through a full day at work. Now, today my battery dropped to 50% charge in only a couple hours use & I only turned the screen on briefly to text a couple times........
Go to the phone menu and set it to LTE mode (w/voice) will use less because there is no 3g connection running at the same time.

There is a script to recalibrate the battery. I looked inside the script, and it just wipes battery stats, so you don't have to do it inside Recovery. However, the apps that wipe stats on the Market do the exact same thing as the script.
I personally am S-Off with the latest leaked RUU. I am on the latest CleanROM DE ICS with the OEM extended battery. I get great battery life. If I wasn't using my phone much, I'd easily make it through two days. The way it is now, I get moderate to heavy use and easily make it through a single day.
I don't run live wallpapers, I keep the widgets to a minimum, I only use Gmail for email, no Social networking services are active, and I have some system apps frozen.
I do have a crapton of apps installed, but very few that have notifications. I remember back when K-9 Mail was eating up battery like crazy. Look for culprit apps like that, there is usually something.
Honestly, coming off my old OG Droid Incredible, anything more that 4 hours of battery impresses me. I am an -extremely- heavy user. 4G, auto brightness, lots of web browsing and games, and my battery temperature often hits 115-120 degrees fahrenheit when gaming. I can pull 4-6 hours on a stock 3.8v or 3.7v battery. I have a second battery and a charge cradle, as well as a 1 amp car charger. I find I'm never away from a power source for longer than that. Further, I just bought a 5000mah battery pack to emergency charge all my gadgets. My recommendation is to drop $50 on a second battery and charge cradle. Battery becomes irrelevant.

Battery is Rapidly Dying

Hey guys, if you haven't guessed, I have an Evo 3D (Evo V 4G, details, details) and I've always used the extended battery from Zlaza. That worked wonderfully. Now the case for it broke and I have to get a new case or fix it. So I'm stuck on stock battery.
EDIT: For the record, I did use the regular battery for roughly two and a half weeks before jumping onboard the extended battery ship.
The Problem:
Stock battery (when I used it) never drained this rapidly. 30 Percent in two hours. I'm not streaming audio, listening to videos checking email or even browsing the web, I'm just listening to music on Poweramp. Occasionally I checked into XDA with it.
I'm on Harmonia (the, what stock should've been ROM for Virgin Mobile) using Buttered Toast Kernel clocked at stock using conservative governor. Any ideas why this might be happening? Is this normal? Have I been sucked out of the realm of normal due to having an ultra large 3460mAh battery? Keep in mind I have wiped battery stats and let it die (really easy now) then charged it up again before using it.
Any explanation would be great.
More in depth stats.

And this one was while I was flashing a ROM and jumping in and out of recovery earlier today...

A few thoughts:
1. Maybe the battery has gone bad (or a little bad) since you had it unused in the drawer for so long.
2. I lose quite a bit of battery every reboot.
3. I only get about 3 or so hours of screen on time when using stock battery
That's absolutely mind blowing. Nonetheless, thank you.

Try going into recovery and wiping battery stats.

30% drain while listening to music is not out of the ordinary.
You could try changing your kernel and undervolting. Might help out but be sure to know what you are doing.
Also battery may be bad.

Damn it, I meant to put that into my OP, yeah I did that.

And undervolting is always an option, I figured using stock clock and conservative governor (along with set CPU profiles) would be enough. I may consider doing that, thanks.
Im assuming its your battery. On my evo battery life fluctuates alot. If i use it alot, i tend to get about 6-7 hours daily. If i hardly use it, it can go above 1 day. Right now im at a day and 12 hours. lol but have hardly used it

I also think maybe you need to charge and let it discharge a couple of times since you havnt used it in a while. This should cycle it and should help the battery retain some more charge.
Hmm, that's something else that I didn't consider. I figured it would be fine because I'd used it in the past... Recalibration it is then.

EDIT: By the way, what ROM?
Viper 3D r192 but the newest r202 has gps issues. i have also changed my kernel to (Bacillus anthracis) i dont think im allowed to say the actual name
Hahaha, thanks. I'll have to try it out.

Just an observation, I bought 3 extra batteries with a wall charger, my original HTC battery is now a year old and there's a noticeable difference in battery longevity, my after market batteries last 30-50 % longer, so after 1 year it's time for a new battery
(Don't ask me for help as I couldn't care if your phone explodes, eh! )
That's always a possibility... I'm on Virgin Mobile and I got one of the Sprint Evo 3D instead of the Virgin Mobile ones... There's always the possibility that it had been lying around in a box for a year or so. Something else to consider I suppose.

Batteries normally will lose the ability of retaining a full charge after many discharge and charge cycles, lithium ion batteries are prone to this as any rechargeable battery

This is probably your problem.
Lithium Ion batteries die slowly on the shelf too. They recommend you store them at 40% if they won't be in use, but there's no perfect way of storing a battery to prevent it from going bad.
However, charging it to 100% and leaving it is apparently really bad.
Maybe you did that before switching to the bigger battery?
Ahhh yeah... that's kind of exactly what I did.
