[Q] Defy+ Temporary bricking due to overheating?

Yeah, got a major issue: My Defy+ is overheating and I usually end up with a blocked phone, which ends up being useless for about 4-5 hours. And it's becoming more often.
I have 2.3.4 on it, but I seriously doubt 2.3.6 solves this issue.
Any tips?

Try custom ROM's and DO NOT flash 2.3.6 full sbf as it's quite buggy and you'll be stuck with it.

You could also try to undervolt the CPU. In what conditions do you get an overheated phone?

How could I do that?
Also, I get it for no reason whatsoever. It gets overheated and that's it. I left it to cool about 4 God damn hours, and yet when I open it it works a bit, then it gets stuck. It's as if the memory isn't well processed.
To give ya an example, I left it over night and even charged it. Everything went fine.Then, got to school, got a break, wanted to listen to a song. Fine, listened to a song. A guy wanted to waste some time on Opera Mini with his Ikariam game. Fine, let him waste that 1 tab and browse online.
But then, when he gave it to me it was stuck.
Wait a lot of time to stop it via Android's button, did it eventually. Left it to cool 2 hours, tried again. Again, after less than 3 minutes of usage (wanted to share a file via bluetooth, but got to the folder only) it got stuck again. This time it was pointless, 30 minutes later I wasn't able to stop it so I took the battery off.
I kinda don't know if I should change it or still have faith in it.
Right now stuff seems worse. Sometimes it reboots itself, but that doesn't help with anything IMO.
BTW, would the 1% battery patch help? Might put that 720p functionality in there as well.

As Auris said, try flashing a custom ROM (CM7.2 is a good choice, stable and fast enough). For undervolting (if you are on a stock ROM only - because CM7 has a built-in CPU manager, accessible from the bootmenu) ), install SetVsel from the Play Store. Like PC overclocking/undervolting, be careful about the values you choose. You'll find a thread in the General section about SetVsel values.
If these ideas don't help you solve your problem, I think it might be hardware related.
Trimis de pe Defy CM9

My defy+ gets really hot on just about everything except stock! Undervolting didn't help, nor underclocking. Putting it in the fridge temporarily helped, but when I started using it again the temp climbed again!
What should I do? :-/

Well, since you flashed custom ROMs (unlike the OP), how about the baseband? I remember that when I flashed CM7 for the first time I didn't get 3G signal and the phone was overheating because the signal was too poor for the baseband that I used. Switched between a few and finally managed to get one with good signal and 2G/3G/3.5G working fine.

I never use 3G, so I've never bothered changing it. By the way... what are the differences between basebands with the same frequencies?
Could flashing a different kernel solve it?
Sent from my Defy+ using Tapatalk 2 Beta

Well, there are different regions - I don't know the technical details, but maybe some basebands work better with certain network operators. It's a trial&error method, you could choose one that works better or one that performs worse.
Regarding the kernel: I have no idea about the heat dissipation, but from what I've read there is a GB kernel that supposedly has better battery life. Ask Auris, he uses it (it's the kernel by walter79).

Okay, seems the issue solved itself, since now it works perfectly :|
I didn't play a game, which was kinda retarded: low quality, a simple Android game, and playing Temple Run/Angry Birds/ Angry Birds Space didn't give you me any issue.
I don't get it.

Cool as the other side of the pillow...

I'm not sure where else to put this (I searched and found nothing) but has anyone else been impressed by this phones ability to remain cool to the touch? I'm using the stock case that came with the US variant of the phone and aside from an APN issue where signals were going insane and the radio tried to connect to a billion different towers, I have not once noticed the phone getting much above ambient temperature.
Is this normal? Can anyone else confirm that this thing just doesn't get hot?
I'm bringing this up because I've owned/used around 30 different smartphones from all of the major manufacturers and the vast majority get quite warm during several normal tasks.
For instance, on most phones I've used, if the brightness is up and I'm gaming for any extended period of time the phone will get quite warm. If I'm charging and browsing the web, most phones will warm right up. If I'm gaming and charging at the same time, things get toasty. If I'm gaming and quickcharging/turbocharging things get pretty bad. If I'm gaming on a "practically magic" iPhone while it's charging- forget about it. Same goes for most phones and video recording.
The Le Pro 3 has remained completely usable during all of those tasks. It's actually downright creepy being able to heavily game on full brightness while quickcharging without my fingertip being on fire within a few minutes.

This is supposed to be the benefit of the Snapdragon 821 processor; fast but at the same time power efficient....

I hear you. Playing Pokemon Go with a Pro 3 is smooth and cool, I can say that playing for about 10 minutes straight and it gets warm, but not hot. Unlike playing it with my One Plus One, a 5 minute session and it gets hot. This phone totally surprised me :good:

Obviously they've made strides, but its not just the chipset. Reviews of the pixel, ZTE and Asus 821 phone all mention how the 821 is better than 820 (lol, as in it can't cook an egg) but they all say it gets warm and the pixels seem to have significant heat issues.
The battery isn't getting massively hot even under quick charge despite being enormous and charging very quickly for its size. The screen doesn't seem to emit much heat either though it's not some AMOLED qhd monster but still. I mean it's obvious that the CPU is right below the fingerprint reader as it does get warm but nothing even gets what I'd consider hot especially for a modern flagshipish smartphone.
I've used supposedly power sipping/efficient chipset before as well as stuff like the original moto x which was literally a heat bomb and none of them have done so well. I'm sure it's not the actual best temperature that a phone has ever been but it's like night and day for me!
Kudos to Qualcomm or LeEco or the battery manufacturer or the screen supplier- they all seem to have gotten it right with regards to heat and efficiency.
I even have the speed up box enabled for all relevant apps and have turned off most power saving stuff and the phone is still cooler than every modern smartphone phone I've used including hugely underpowered ones.

Good to know, if anyone else has this issue - mine was deleting T-Mobiles default APN and making a MetroPCS one (incorrectly), then deleting that and having it automatically revert back to T-Mobile. Once I cleared everything and manually put Metros APN stuff correctly everything cleared up and has been fine since.
But during that half morning when I couldn't figure out the issue my Pro3 was getting quite warm and I was ready to return the thing. The issue remained even after a factory reset until I manually adjusted the APN.

My situation was different then. APN was fine but it somehow kept frequently switching LTE bands/towers my carrier offer which caused ever frequent signal fluctuation.
Nothing could fix it until I moved to CM.

Very disappointed to buy a HTC 10, and some questions

Good afternoon to all, I hope you can help me with this situation.
I have 20 days with the HTC 10, and I can not be more disappointed of its performance, and coming from a galaxy s6, but we go by parts.
1- the phone, it gets very hot, very fast, especially after updating to nougat 7, I mean, with 15 20 minutes of surfing on the web, it reaches temperatures between 40-44 C ° (104-111 F °) , At this temperature it is uncomfortable to hold. Is this normal ??
Taking into account that I do not play, I only watch videos, I listen to music and web, because I just did a hard reset, which brings us to point 2.
2 - It is the first time, I update an android version, and a big error appears, once updated to android 7, the keyboard stopped working (swiftkey), so I could not access it because it was protected By password, and the keyboard in the start section, never displayed. I had to do a hard reset with only 15 days of use, seriously WTF!
3- Due to the warm up, the battery life is quite poor (between 3.5 and 4 hours of screen, no play, or take pictures all day, turning off mobile data at times and wifi, is this battery drain normal?
The battery come to exhaust quickly, especially when the phone is very hot, when restarting the phone, it eats 3-5% of battery every time.
When taking photos the same, the battery drops very quickly.
4- I normally play on a PC at 60 fps, the phone when playing video on youtube, has a slight lag or "stuttering", this jumps out at me very easily, although there are people who do not see it at all, I do by The same as I mentioned earlier.
When playing video youtube on the phone, the camera movements are not smooth, there are micro-cuts to the FPS, and it is very annoying.
5- before upgrading to android 7, just install a game, "realm defense, hero legends", a very popular game on android, and felt like it was under 30fps all the time, my previous galaxy s6 handled this very smooth,
6- Points 4 and 5 are solved by activating the "high performance" option in the menu of developers, the lag in the videos disappears completely, and the games feel very good, but with the consequent increase in battery usage and Temperature, seriously WTF again.
The phone according to CPUZ has a load of 15-35% all the time without loading any application, this is normal in andrid 7 ??
The phone is in stock status, with the update of the operator, I have no ROM installed, and I have no idea how to do it, because I would not like to lose the warranty.
Any recommendations to this situation ??
THANKS and excuse my bad English.

May want to ask for a replacement. None of the issues you mentioned here and I have been using this phone for almost a year.

No these are not normal. Obviously something is running around causing the CPU usage and eating the battery. Given how many problems you're having I would do a factory reset, see how it goes without installing any apps. If things get better that'll help your pinpoint the troublesome app(s). If not, a replacement is in order.

I'll second that, although I've only used mine for about six months. I do admit that running Android 6 the phone did seem to get hotter than it does with Android 7.
That being said, when I'm running a game battery life does suck, and it does get warm. I think I'm about 5 to 6 hours of screen on time, but I'm also bone stock with a bunch of extra apps in the background.

Thank you friend, I am interested to know more about your experience with the phone, why you only had 6 months?
Could you fix some problem that he gave you?
Greetings.

I have HTC 10 for one year and several days, never had those issues.
I admit HTC storage r&w speed is slower than S6 because of emmc5.1, but mine is smooth enough.
I also recognized the battery life is shorter on Android 7.0, but it's a general issue for phones upgraded to this version of Android...Not just HTC10, Sony, Samsung etc also has this problem.
As for SwiftKey stopped working, I have no such an issue, in fact I'm a mod of SwiftKey.
At last for the temperature, mine gets 38 °C while fast charging; 42°C is max while playing heavy games.

Mine gets 40°C Without doing anything, and playing reaches 44-45 °
And it seems ridiculous, that when doing this app can not with the 60fps, for a little ball in 2D.

Again, it reaches almost 60 FPS, activating the high performance mode.
Thanks for sharing your experience.

Sorry, I should clarify...
I've had the phone for about 7-8 months now (longer than I originally thought, got it back in September of last year...) and got the update to nougat about 4 months ago.
When the phone was running marshmallow, it would get warm while working on tasks that aren't CPU/GPU intensive. With the update to nougat, it definitely helped with the heat production. That's not to say it doesn't get warm... If I'm playing Rayman Classic on full brightness, that phone gets really REALLY warm. But when playing Deus Ex - The Fall, even on high brightness, it doesn't get uncomfortably warm like when playing Rayman. Also, basic tasks don't overheat the phone like they would on MM.
I should note that I typically leave power saver turned on as well. I've found it doesn't affect performance noticeably for myself. I've also had Boost+ optimise all foreground apps from the overheating nightmare on MM, and I hadn't bothered to turn it off... These could play into the heat production of my phone as well...
My time with this awesome phone has been so short due to my contract with my former service provider...

I think most of your issues will get resolved after installing Custom Rom. Infact I am in similar situation like you. I can't root my phone due to warranty. As i know for fact that in my country HTC charge huge amount of money even for small issue. After spending that much money on repair, there is no guarantee that phone will work fine cause engineers are not capable enough, maybe cost cutting by HTC. Meanwhile i would suggest select SRGB instead of Vivid display, it will surely reduce heating problem to some extent.

SM-G960U reboots when screen turns off (Second phone!?)

I have a T-Mo SM-G960U Galaxy S9 (Non-rooted). It's about 3 months old. It's on the latest firmware (G960USQS3ARG8 - Aug 1st, 2018)
All of the sudden this issue started occurring where the phone turns off when the screen turns off?! About half the time it reboots, but other times it just shuts off. This happens if it's charging or not. Crazy enough, this exact thing happened to me when I first got the S9, and they sent this replacement which I've been using for about 3 months with no issues. What're the chances I'd get two phones that have that have the same issue? Obviously, I'm thinking it's something I've installed, but I didn't make any changes when this problem started happening tonight.
I looked thru the recently updated apps, and nothing looks suspicious.
Also tried turning off all the settings that deal with the screen - blue light filter, Always on display, but nothing seems to help.
Put the phone in safe mode, problem still there.
I wiped the cache partition - no joy.
Took out the SD card, still reboots.
Any ideas?
Thanks

It's really odd but I have a Galaxy tablet that has done the same thing since I've had it but it has something to do with the wifi. As long as it doesn't switch between my 2.4GHz and 5GHz channels it seldom reboots so I had to split my wifi. It still does the reboot thing but not quite as often. I truthfully don't think that your S9 problem would be that though. If you have the Snapdragon version run an app that will check the core temperature. Maybe there's an app causing it to overheat. I say Snapdragon because there was a discussion where folks were saying their phones with the Exynos chip wouldn't read the Temps.

@Tel864 thanks for the response. Yeah, don't think the wifi thing is the issue. It's weird because it's immediately turns off when the screen is off, so it's almost like a setting "Turn off device when screen is off"...obviously there is no such setting, but I'm baffled.
I installed a simple temp monitoring app, and it's running about 100F, but spikes up to 115F. I'm not sure if that's hot or not? The device feels cool like it always does.

P3XL Suffering from lots of random apps closing/freezing,etc. Any ROM that will help?

I have a P3XL that's roughly 1 year old. It's seriously slow and laggy and stutters like none other. If i'm in Chrome and browsing reddit, it can crash from having a long page of images open. Using simultaneous apps like Spotify and Instagram kills the phone. I was using flashlight and making a call at the same time and it crashed.
I originally used stock, that was the same. Switched to Havoc OS and it's pretty much the same. I can only guess this is from poor RAM management. Battery life is crap now too. Doesn't last me till 6:00PM on a low usage day.
Any ROM suggestions? Or is there something here i'm missing? 4GB should be enough... the P2XL was absolutely fine but this is atrocious. I frequently want to toss this device across the room.

You may have a bad battery which is causing voltage/amperage problems and glitching. If you've already done a fresh clean install of the factory OS and still have issues that'd be my next guess.
Did you regularly run it below 20% or until dead?

Yeah I gotta say that sounds a battery issue or something else going on. I've been running stock Android 9 rooted with Kira kernel for about half a year now and although there is still a lot of reloading (especially when using chrome or internet browsers with lot of tabs open) it's still snappy and reloads quick. I've never had anything crash.
Unfortunately I have no clue how to test a battery for proper amperage. I know 2 ways to get an estimate on capacity with accubattery and extracting it from a bug report but I don't know if that will help with identify it or not.
It sounds almost identical to the same issue I had with my LG V20 which was a bad battery that would randomly shut down with around 15-25% capacity left when it got that low and when I changed the battery it fixed it

I guess it could be a bad battery causing voltage issues. I have done a fresh clean install of factory OS, and still have issues. I would say i'm average when it comes to running it below 20%. I don't do that often, but sometimes it does. I rarely let it die completely.
Best scenario would be to go through Google Support?

Yeah, mine is crashing hard. Hard enough that it's one of the poorest performance phones i've ever had. And that's saying a lot lol.
I'll try to use accubattery today to see what I get. It doesn't shut down at 15% thankfully.

My V20 wouldn't always die at those ranges but it happened pretty frequently. Do you notice a difference with it plugged in?
I would definitely start from scratch if you really want to troubleshoot this. Backup everything then flash a stock system image from Google with the wipe all command and start from there and see. If it still does it then it is most likely a hardware issue.

Sounds more like a cache problem to me.....dodgy nand chip. Needs to be replaced no matter whats causing it. If you cant get rid of it after trying everything including swapping the active boot slot from a to be or vise versa
