Critical battery temperature - Milestone 2 General

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

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

Universal suddenly shuts down; battery or other problem?

I recently acquired a HTC Universal for dirt cheap, and have found the first problem to explain the low price: Whenever I'm using a "power-hungry" application (TCPMP, Internet via Wi-Fi) it eventually just blacks out. Full shutdown without warning.
When trying to reactivate the unit, it reboots as if after a soft reset.
In fact, if I try to reactivate it too quickly, even the reboot fails.
None of the above happens when on external power.
This leads me to think that it's nothing worse than a battery that's lost its mojo, but since there is no warning about low battery, and when the reboot finishes successfully even SPB says the battery is somewhere around 70%, I want to run this by you guys.
What do you think? Just go get a new battery, or is there something else going on which will make buying a new battery just a waste of money?
I'd say it's the battery, 99% sure.
I'ts gotten old and its voltage breaks down under load. If you have proper equipment and a glimpse of an idea what you're doing you should drain about 300mA from the battery and measure its output voltage.
You'll most likely see it going below 3.0V quickly.
I'm afraid I don't have that equipment, but all I really needed to hear was that it's probably the battery.
Now I can stop thinking about it and just order a new batery.
Unexpected reboot - Apparently bettery issue
Hey Holybear, my device shows exactly same symptom, If possible let us know if bat replacement solved the issue>

I knew I wasn't the only one withthat problem. I think i've prooved it to be a battery faultt. as if you taake te battery out after it gets to that stage where you just can not get it too complete a boot up without it shuttinng down again
take out battery ,place finer oveer all battery trmminals and plug inn your mainss charger it should now boot up and runn fin off the charger unless your finger slips off the battery terminals. thisshsowws it's the temprature sensor in the battery.
I posted a more in depth reply to a guy in the wm6 threads as wifi heeaating up battery wass shutting off his device as well
@ cyberjak
Hmm, the idea that a temperature sensor in the battery causes this problems is interesting. I'd just expect the device not being cappable of rebooting instantly, because there should be a hysteresis implemented in the battery's protection circuit.
I had the exact same problems and described them elsewhere, but in my case it surely wasn't an issue of temperature.
I'd suggest to take out the battery and wait about an hour for the device and the battery to cool off. Most likely the battery will then take a complete boot but shut down soon after that - without having gotten near to "warm" yet.
If this happens you can be sure that the battery itself is dead without needing to measure anything.
Okay, to tell you what I tried:
I ran the Universal until it spontaneously went dead.
Started bootlaoder to see how much longer it would work on that. Was a bit longer, what with low energy consumption, but soon even that wouldn't stay on for long.
Then decided to try the "old wives' tale" (meaning I don't know whether there's any sense behind it or not) of putting the battery in the freezer for a little while.
When I took it out and let it get back to normal temp, I plugged it in and after a while booted the Universal. It showed 40% battery, lower than it had ever gotten lately.
Recharged for a full day.
Tried TCPMP: went dead after three minutes.
So in my experience the above didn't help battery performance.
Am going to get a new battery in a few days; I'll keep you posted on progress as I try with a fresh battery.
I had the same problem, whenever i did something cpu intensive, it would just black out.
I just bought a new 3100mAh battery. Best thing i ever did. It might be thicker now with the new battery, but it actually feels more comfortable as a phone. Plus the new battery only cost 13 odd quid, so definately well worth it. Oh and it doubles the battery life (3100/1500 = ~2... duh)
Hope that helps.
oh you know wat i have the same problem with my Jasjar and the bigest problem that there is no batteries on market for Jasjars in my country....its looks like im living in Jurassic Century!!!
If you want i can send you a battery xplayer, they're quite cheap here.

I revived two batteries by intense cycling to work quite well again. They still black out at 20%, but only under extreme load (active gsm connection, active wifi, bluetooth and having to render a webpage).
But you should be able to discharge them below 25% at least. Else they're most certainly "too dead" already. And you should do at least 3-4 cycles.
My guess would be that the freezer finished your battery off. I don't understand how this method should work anyway, as lower temperatures reduce the time affected capacity loss. Actually the best place to store a LiPo or LIo battery is the fridge, charged about half the way.
But I also ordered two 3100mAh batteries. I'm using the Uni as a laptop replacement and the permanent wifi usage together with some cpu load and the backlight kicks the battery's ass quite hard.
In Germany the China 3100mAhs are overpriced and it's hard to get your hands on an external charger, but on Ebay.co.uk there's a seller that offers battery and charger as a bundle for about 15€. This will give me a solid 6000+mAh per day and should be enough to forget about virtually every setting related to power consumption

If you haven't donw already, take a look at Ebay.com, co.uk etc and look if one of the sellers there will ship to kurdistan. You may be lucky

Thanx for helping the guy,yo folks on xda are the best
Just to give you all the end of the story:
I ordered a regular replacement and a 3200 mAh one, and both have returned my Universal to a well-used life.
Thanks again to everyone helping me out here.
For you guys does the device switch off only when the battery is low, or any time. Cause I have this problem as well, and I was SURE that it wasn't a battery problem until I read this thread. The phone switches off intermittently, sometimes after only 3' talk time right after it had been charging for a full 8 hours! Also, usually if I let it sit there for a few hours I could then turn it back on and it would last a full day, so I knew it wasn't due to low battery.
The overheating theory would explain my problem, as, now that I think about it, all my seemingly-random shutdowns were during radio activity (making or receiving calls, especially when the phone was searching for signal, or wifi, which would almost instantly kill it). Strange that it overheats like this, most phone batteries simply run out of charge faster and faster until they can't hold a charge at all, but mine lasts almost as long as it always lasted even though it's 2 years old - unless I get the shutdown thing of course.
I asked this in another thread, but since this one is full of people who got replacement batteries I'll repeat my question here as well:
How much thicker than the standard battery are the 3100 and the 4200mAh ones?
I also got this problem recently, so I bought a new battery and although it's only a 1600mAh battery it runs great again
hey roodkapje ive got that same problem with my battery for my spv m5000 the bad news is that i cant get that batery in barbados so im all out to see

X10 As In-Car GPS

Hey guys,
This issue has been brought up in a few threads, but not properly discussed with a solution. Issue is as follows:
X10 + Gps Application = kick ass gps system with beautiful screen
Having the screen on drains the battery heaps, so I bought a in-car charger. The first one I bought was a crappy cheap one, so I replaced it with a good one that charges the phone properly.
THE ISSUE: After about 20 minutes driving, the combination of the display being on and the phone charging causes the phone to get quite hot (about 40 degrees C from my calculations). This triggers a feature in the phone to disable charging until the temperature reduces.
END RESULT: Overall, the battery drains even though the phone is plugged into power. It drains reasonable slow (about 40% for 2 hours driving) but is still frustrating.
POSSIBLE SOLUTION: I have not rooted my X10, but I was wondering if using the "setcpu" app to reduce the CPU speed to like 233Mhz or something once the temp goes above like 35 degrees may help. Could someone confirm or test for me?
INTERIM SOLUTION: If I really need the phone to charge, I just lock the screen while driving and listen to the voice commands. This results in the phone not overheating and charging whilst driving. If it helps, I use Sygic, Google Navigation and CoPilot, all with the same result of overheating.
It would be great if we could get to an acceptable resolution for this issue as this is a feature that I really want to be able to use often,
Thanks guys, look forward to the replie!
Starsky.
Also, running the .20 firmware on a generic UK x10
im on build .23 - rooted, i just drove about 4 hours with both Google Navigation & Motonav at the same time, had no problems at all!
im not using setcpu.
it might also get warm from the burning sun.... try placing it away from direct sunlight.
Thanks for the reply Joel.
Im in Australia so its winter at the moment, no worries about the sun
I have the phone in cradle connected to the air vent, so I did at first think the hot air from that may be causing it to overheat, so I turned the vent off but it hasnt made a difference.
It seems to be a random amount of time before the phone gets too hot, some days it happens after a an hour, other days it happens after 10 minutes, not sure what causes it. I might try rooting the phone so I can get .23 firmware and see if that helps, thanks for the feedback.
Cheers.
Since you have it placed in front of the vent, the air conditioner blowing cold air on it should be able to keep the temperature down
Sent from my X10a using Tapatalk
You may want to check your car charger output.
If the output is very high, say 1A, your battery will get fully charged much faster, phone & temp will be much higher than say at 500mA.
you definitely do need to check your car charger. I have it plugged in with Navigation on (which leaves the screen on ) and it actually GAINS battery charge. Looking at about 1% every 5 minutes.
I have same problem. Need charging while using navigation but it gets too hot. Will try to mount in front of airblower. Did not have this problem with x1.
Sent from my X10i using XDA App
I have the same issue here. The phone heats up quite a bit when using Google navigation and it being plugged in to charge. I'm not sure if this is normal.
Using Google uses both the GPS and Data functions and might be the reason why the phone gets warm. It works harder!
I use IGO 8 and have no overheating issues whatsoever. I am rooted and use SetCPU (using the default "on demand" option).
My battery lasts a very long time anyways, but charging during use it does not cause overheating.
BTW OP! On most cars, even if you have a individual vent closed. If the heating is on to the rest of the vents, that vent will still radiate heat as warm air is blown into the back of the vent fins and they will heat up. Put your hand over this and feel it to confirm. I use a windshield mount and the phone is in direct sunlight a lot of times.
thanks for all your replies.....
quick question, those of you who have said they are able to keep the screen on and charge at the same time...which charger are you using, the official SE one?
If not, can you post a link to where you bought it?
Cheers.

[Q] Heating up while charging

Does everybody's vibrant heat up like crazy when they are charging their vibrant?
yes I have two of them and they get pretty hot ( you can feel it in the back side underneath speaker)
Mine as well gets hot but it doesnt happen all the time. It's charging right now and it isnt doing it. Weird...
it usually won't get hot unless you're USING it while it's charging.
Mine used to go up to 116 degrees while charging, but them I swapped it out and my new one barely goes past 95

Try disabling the Wi-Fi and GPS while charging it....Seems to stay cool when I do this on mine.
When using up a lot of energy and charging at the same time it causes the heat...this is one of the problem with the current battery tech :/..
from experience with other phones..wifi + charging = hot as hell..if you really must use wifi while charging for say tethering then I suggest putting it on a metal surface(which will act as a heatsink in a way) and it won't get hot.
I'm from down south.. And mine sits at 110... seen it at 115 before... Ive never had another phone get as hot..

I noticed this as well too. Seems that it is more noticable if you put in on charging soon after using wifi/gps intensive apps. Maybe they stay on longer when it sees it is on ac power? I even had one point where after over an hour charging there was no noticable gain in battery charge. I imagine it was using so much power that little was left to actually charge the battery. In all cases, a reboot fixed the issue and it charged quickly with little increase in temp.
Kinda remides me of my previous windows mobile phones. Sometimes an app would "hang" even though there was no error message and the app appeared to close down fine, I would notice my battery would be used quickly and the phone would be very warm. Usually it was an app that used wifi or gps that caused the issue. Maybe the app crashed before giving a "release command" or similar to the hardware and it kept on running at full power?
It happened to me twice. My phone went past all of yours. It got to temp of 143F. It was really hot all over the phone. I had to turn it off and take out the battery for it to cool down. It wouldn't even let me charge it cus it was too hot when the phone was off. I woke up to 18% battery charge after 7 hours of charging. It said that the display was using most of the batteries. I believe when you plug in your phone, i noticed a change in the brightness setting and i dont have automatic brightness enable. Now i make sure i fc everything before i charge and the brightness is at 0.

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 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.

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.

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'...

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.

Hot priv (not warm)

I know I'm not alone on this one, I have to constantly cool down, it's totally intermittent and it's scalding....I hope it will be fixed soon and not just a myth. the folks at ATT said it had something to do with being more green. I think if an app is spinning in the background, it should be told to stop....
Mine gets very warm very quickly, but hasn't (yet) gotten hot. Certainly not "uncomfortable to hold" hot, anyway.
yeahh, i just received the phone and there are a lot of downloads an updates, but the phone is really hot. with a normal charger i hane no charging at all. the drain is bigger than than the energy from the charger.

I have been told by BlackBerry tech support the heat temperature flare ups could be caused by the encryption that is being done in the background.
Mine doesn't get to hot but it does get as warm as my note 5. I purchased egrip stickers from amazon to improve the grip and it has also helped with the comfort of the amount of heat you feel while holding the device in your hand and my pocket
I found a great app called "ShutApp" It let's you shut everything down that's running in the background. I have 117, It's running so much cooler now and the battery is lasting longer.
It's still not fixed got very hot in airplane mode plugged in at 100%, it dropped to 97 still plugged in So it must be something to do with charging.. It also just comes and goes as I'm working or watching a video...but sometimes under the same load it stays cool....
12/7 3rd party Camara apps are really cooking, and with short use maybe there should be a handwarmer app (lol)
12/11 I'm sad that this is electing my future non removable battery's life! ..at 100% I reboot in airplane with no apps running in background and plugged in it returned to 99% and started baking.. this is a power problem......
Yes my BlackBerry does get hot for no reason. All my apps are shut, last night i had it in my pocket and i felt it on my leg very warm. As I'm typing this right now i also feel it in the middle back of the phone. I really hope they fix this. As for battery life i am very disappointed, I thought it was supposed to be 22 hours and my lasts like 8 to 10 hours. I even got myself a Aukey portable battery charger and Aukey quick charger, it does charge fast like 1 hour and 30 minutes but it also drains quick. Apparently what drains it the most if being connected to WiFi. Really hoping they find a root for this or fix all these problems or I'm going back to Samsung.
the last update is solved this problem?
Serious hot spots have occurred in Airplane with minimal background while just working on a pic or document.. This is a serious problem and is leaning towards being a hardware issue.. Even though it helps to run an efficient system .. IT should be able to tell whatever when it is getting that hot to cool off....
I will hope to exchange it a third time But not until I know the replacement they give me isn't nt just another of the same....

The priv is the very first of its kind but here are some things you can do to cool it down
1: Turn The Brightness Down- most phones tend to heat up because the battry is pushing alot of power to the screen to make it brighter
2:Android: The Priv is the first blackberry not running the original OS; It's now running on Android Marshmallow which has a lot of animations and alot mor functionality so this could also cause it.
3: Replace The Battery: Yes I know it's the battery that came with the phone. I have 3 friends with the priv and when 2 of them went from stock battery to generic there phone did not turn into a brick out of the oven!
I hope this helped!

i had this issue for the first 2-3 days of getting the phone. disabled a few of the 'neat' settings ( wake on pick up, bb keyboard predictions, using swiftkey instead of bb keyboard, maybe a few others ) and since then it doesnt even get warm, like at all.. had it on for 20 minutes playing a youtube video and the phone was still cool...
Bought mine 2 weeks ago, it does get pretty hot (to the point of not touching it sometimes).
Only when I play games or snapchat, browsing internet doesn't heat it too much.
Especially when charging, so I try not to use it as much.
But the battery drops the same so it doesn't matter much, I just let it cool down and continue
Are you on any marshmallow rom ?
I haven't had any problems while using marshmallow.
