strange scenario----> weather is affecting factor??? - HTC Desire S

Hi everyone....
i want to discuss and ask some interesting problem related to my DS
last summer my DS had a problem of self power off whenever i put it in my pocket...in in winter i moved to china and here temp. is like -10 to -19C....but in winter that problem was disappeared ...but in mean time in winter sometimes flash light not turn on and keep giving temperature error.......now here in china temperature is almost stabilized and same tuning off problem is appeared.......Any suggestion to over come this problem....

Maybe your battery or another element has some problem and overheat or something like that. Usually electronics components work better when they're cold.

[Q] HTC One X almost on fire

I have read allot about battery problems lately and my conclusion is that every HTC one X heats up badly when browsing internet on wifi or playing 3D games.
Just came across a website where they said that the one x easily gets 45 degrees with just browsing on the internet, and gets 63 degrees celsius by playing 3D games within the first 20 minutes...
I guess these temperatures damage the battery badly?
I contacted HTC and they tell me i need to send the unit in. But if all units have the same problem i dont think its fixable by hardware repair... Its useless to send the unit in if its not fixable.
How do i report things like this or what can i do as a customer??
When contacting HTC you get someone at the other end who doesnt care at all or never heard of the problem. im getting very angry about this. The phone is useless! when doing even the smallest stuff on the phone wil drain 1 - 4% battery a minute. the phone heats up and in settings the battery status is shown as overheat...
This needs to be fixed with software somehow!
re
"The battery should be stored in a cool place. However, it should not be exposed to frost. Storage at high temperatures (eg, heated cars) accelerates the aging process"
Most companies in such cases says that they didn't heard 'this' problem form customers.. It's normal I don't know that in one x is software or hardware problem. People write on other forums that high temperature in one x is 'normal'.
I don't know what You can do really.. Meybe it's not flexible ( I think probably ).
If You are so angry, just give back this phone to the place of purchase like as "lack of conformity" - (special warranty). In Poland exist special previsions to 'fight' with seller but I don't know what rules are in your country..

[Q] Overheating when using navigation & loading?

Hi everybody, hopefully my problem hasnt been posted yet.
I am from germany, so I am using Navigon Software for Navigation. Some users reported this problem too, but I dont know if its Software or hardware related.
When I use Navigon while charging the phone it takes about 15minutes, the Phone gets freaky hot around the camera and the status LED flashed red-green-red. The accu temperature is shown as 50 °C (i thinks thats the maximum before the phone trys to save itself by stopping the charge)
Has anyone similar problems? Would you suggest a software problem? My old Desire gets pretty warm too, but not so hot that it goes into save mode.
Todays the last day I can return the phone without amazon questioning anything (14th day). So what should I do?! Its not that I use navigation and charging all the time, but it just sucks.
It shouldn't get that hot no, I'd send it in.

[Completed] Who can explain: sensor readout is stuck ONLY DURING SUMMER MONTHS (Neo 003)

I know that this sounds ridiculous, yet I have observed this issue for the third year in a row.
My Neo 003 smartphone (Android 4.2, 2013) fails to read out its sensors (gravity, compass, location etc) during the summer months!
All apps reading the sensor data will 'freeze' or 'hang', or simply report 'waiting for event'.
The values for xyz are stuck at odd values, or change once or twice before hanging.
I can provide more details on the sensor hardware used, screen shots of these weird freezes if interested.
It took a while before I noticed this obvious dependency, as it is so odd and unexplainable.
After working flawlessly for several months the sensor readouts would start to hang more often in later spring of 2014.
The effect got worse over time; I suspected a hardware failure and was pissed when they got stuck for several months in the summer. I contacted the manufacturer and was brushed off - FU! So I kept trying.
To my surprise the sensors would start returning values more often in early fall, and would run perfect again around October, for the entire winter!
And then the SAME happened in 2015 again! And again this year!! Currently all sensors react flawlessly to motion, shaking, rotation. They had become flaky around April, hardly worked in May and failed during the summer, came back to life several weeks ago: I checked them almost daily to see this drift of functionality. Just WHAT is going on here?
I have tried to fool my phone by resetting the date and not going online to keep the wrong time - it did not affect the dependency. It failed to run in summer when set to winter dates.
I use the phone at home exclusively and always in the same rooms. There is no significant environmental change I can think of that could affect this (temperature, pressure, humidity). The problem occurs as well on the road anyways.
I am a phycist by trade, in fact I was quite involved in electronic measurement and data collection for many years.
This phone is driving me nuts, because I can not come up with a resasonable explanation for its odd behavior?
Android seems to use a quite thick layer of software drivers and event handles to manage the sensor readouts; it looked rather confusing to me and was not straight forward as I hoped for.
Since the failing mechanism is NOT hard but 'soft' (slowly shifting from working to failure over several weeks, and back to functionality in a similar way) it can not really be a software 'numbers' glitch, or?
Could other apps (about 600 are installed) interfere and block the readout? But why only in the summertime months??
I REALLY want to learn about this phenomenon, because it is about the weirdest problem I ever saw on an electronic device.
Who can shed some light on this, who can explain how Android initiates the sensor chips and reads them out?
Who has seen the same effect on other phones or devices?
What tests should I conduct to isolate this unique failure pattern (phone in the fridge, in a Faraday cage etc).
I do not want to break my Neo, despite its age it works quite well and runs stable, with its original ROM in place.
It took me THREE years to come forward with this issue, because I could not believe my own observations.
Now it is time to bring it up.
Please explain my spooky phone to me - thanks a lot!

Greetings and welcome to assist. It sounds like defective hardware and something that is pretty much out of scope. There are several sensor testing/calibrating apps you could try to test your sensors. That is all I can suggest really
Good Luck
Sawdoctor
Thanks for looking!
It has NOTHING to do with calibration.
If the sensors do not react during the summer, they can not be accessed anyway.
I installed and tried a dozen or so sensor apps, all show the problem, if in different ways (frozen, 'waiting for event' etc).
Noticable is that the orientation readout is consistently showing the same '(fixed) value 0.0130 for x, while y and z show flat 0, every time the error occurs. The compass is entirely frozen during these times as well.
The Neo uses different sensors for magnetic, gyroscopic and gravitation measurements.
I would not have asked here, if I had ANY clue about this causality.
WHAT is throwing the orientation/gyro sensors off for several months and ONLY in the summer? Inside my own house, at fixed environmental conditions?..

I'm out of ideas then all it can be is faulty hardware. Maybe try asking in android q&a to see if you can find any other Neo 003 users see if they have the same issue or not
I have raised this issue in the NEO 003 thread, without results. I read about other phones acting up on their sensors, but never due to DATE patterns; typically they fail entirely or due to firmware mods, driver issues etc.
I AM willing to believe that the temporary failure of my NEO 003 sensors is hardware related, BUT:
which miniscule environmental variable change could possibly let the sensors fail to respond to reading them during the summer months, inside a regular home?
What IS different in July compared to March? Neither gravity nor magnetic fields fluctuate in any reasonable range throughout the year.
Nor does temperature (which varies far more depending on other factors; the phone shows board temperatures of anything between 39C and 60C depending on CPU load).
Room humidity is lower in the summer than in the winter time (heating in Central Europe), but then the problem happens inside a home as well as outside on the road. And there humidity can be anything from 30-100% during the day.
I even thought of electro-magnetic interferences, but there is nothing in my home that would only disturb electronics in the summer. Plus the problem is not limited to my own home anyways.
As a physicist I AM at the end of my wits. For me this is downright 'spooky'.
Never would I have brought this up if I had the faintest reasonable explanation, yet I can prove that the observation is true. It took me THREE years (winters and summers) to notice the regular, season related, repeatability of the problem!!!
I have two more choices:
- entirely resetting the phone and rebuilding it; with 600 apps installed this may take months to get them all tweaked and running again
- conduct more thorough system time modifications (prohibiting date adjustments for several days in a row, while booting the phone frequently and using it offline), trying to enforce it to accept SUMMER as the current season. First tests failed to trigger the reported sensor failure.
The fact that failures do not occur 'black/white' but slowly (more and more often failing to return data, from 'alive' to 'dead' and vice versa, over several weeks) does NOT speak for the software dependency. A number glitch would kill the readout hard at a given date; yet it does NOT.
As you can see I AM pondering quite a bit, unwilling to accept a phenomenon that defies my understanding of this universe. This IS my 'Einstein moment': spooky behavior beyond my horizon, unknown entanglements, as mentioned earlier.

Help me diagnose my overheating/battery-sucking D6616 (TMOUS)

All right. Let me start by saying I've had this phone since it first came out and until very recently it's been a great device for me. Yes I have the T-Mobile US version with a locked bootloader, which sucks as far as ROMS etc. go. Yes its GPS can be less than reliable occasionally thanks to issues with Lollipop, which we're stuck with. But everything else it did just great. The battery life was one of my favorite things about it- if I started a day with 60% it would be just fine.
Until about a month ago. About a month ago, the phone developed this <sarcasm>neat trick</sarcasm> where it would get really hot and burn through about ten percent of its battery or more in ten minutes or less.
My initial thought is that I'd have to wipe the phone and start from scratch (followed closely by rooting and loading up an Android Nougat ROM, but we all know how that's worked out for the D6616 ). But I'd really like to avoid wiping if at all possible.
Here are my working theories, let me know what you think I should do to further diagnose:
Some New App is Responsible- The obvious candidate. I installed GSam Battery Monitor to look into this, hoping to find an obvious culprit to delete. Sadly the only apps using more than 2% are whatever app I've been actively using with the screen on, Android System, Kernel (Android OS), and Google Services. I uninstalled a bunch of unneccesary apps anyway, but it didn't improve things very much.
The New York Subway System - Stay with me here, it's not entirely a joke. I live in New York City and recently all of the stations had cell service and wifi activated on underground platforms, but not between stations. So when I ride the train (a significant chunk of my day as I freelance work in clients' homes) I'm going in and out of service constantly. And things do tend to improve when I turn on airplane mode when I get on a train. But not a lot. And the overheating and battery sucking behavior does happen sometimes when I'm aboveground.
The Battery Itself- This is the one I'm most worried about because the fix just sucks. The phone is now over three years old, and I do use it pretty much every day, only turning it off at night or when I'm traveling abroad. That's a long time for a lithium battery. My understanding is that near the end of their lives, they do overheat and lose charge quickly after a while. Since this is a waterproof phone and I'm in the US, I'd have to ship it to Sony for 2-3 weeks a repair if I want to keep it's waterproofing abilites (I do). I'm betting that's not cheap. My real hesistation with this one though, is that my phone is about as old as most other people's on here, so if this were the case, I'd expect a ton of users here or on T-Mobile's forum to be complaining about the same problems. I haven't looked closely but I haven't seen many people with this problem.
So that's where I am. Any ideas? Things I should try out to get more info? I'd really like to solve this, and I'd bet figuring out on here would help others in a similar position. Thanks!
Managed to get some relief by wiping the phone. Didn't restore it to the good old days of 60%-in-the-morning-no-problem-all-day, but was decent. But now it's come up again. I can and will wipe the phone again if I have to but if there's a more elegant solution someone has found over the past 10 months or so, I'd love to hear about it.
Thought I'd solved it when the sd card died and I wiped/replaced that. But then it started having the same problems a few weeks later on a new card. I wiped the phone and the SD next and I'm still having issues. Heck, I've even had it heat up while in TWRP recovery mode, so I'm pretty sure we're looking at a hardware issue.
My first instinct would be the battery but according to the internal temp sensors, the battery isn't that hot (39 or so C). The CPU on the other hand is getting very, very hot (spikes to 72 degrees C). This tallies with what I feel on the phone looking at diagrams of the innards: the hot part is about a third of the way down from the top of the phone, where the CPU is.
Any idea what bit would have to be replaced to fix this?

Huawei P9 Battery issue thats "somewhat" confirmed by Huawei

OK it all started when the temperature where i lived dropped below 10 degrees Celsius and my Huawei P9 could not hold a charge for more than 30 min. when being outdoor.
I contacted Huawei about this issue and was told that was normal and a safety feature in my phone and i should use it out doors and keep it in a case and in my pocket.
Well thinking ok then this kinda beats the point of having the phone if i cannot use it out doors for 6-7 months a year and also no rely on have a phone to use for calls say should my son or some one else get in an incident where you would need to call for help or you wanted to call a taxi or just take a picture ..... i heard that some phone can do this now adays
So finally i convinced Huawei that the phone should be looked at by a repair shop that they used and i send it in and got the reply nothing wrong with the phone ... but it would still just die after being in my pocket and taking a 30 min walk.
So back to the repair shop it went, this time it came back with a message saying that they changed the main board of the phone ... Nope did not work and still the phone would just die after approx 30 min while in my pocket after a walk out side.
3rd. time back to the repair shop and the reply was, Nope nothing wrong with the phone and you just have a phone that you cannot use out doors in temperature below 0 degrees celsius
Well this kinda blows... so i have had the phone for about a year and i cannot use it out door on most of the year and ... BEEP*** so i wrote Huawei again and again to get them to find a solution for my problem
either they got tiered of my complaints or something else but all out of the blue Huawei wrote to me on facebook saying that well they are now aware of a battery issue on the Huawei P9 phone ... i cannot get the official information from them confirming this but will share the message i got from them on facebook "image attached to this post."
Translated from Danish to English it says:
There just came some news about the issue you're experiencing.
It turns out that there is a problem on some of Huawei's P9 models, as you describe it.
As I said, I have received a mail tomorrow that the problem can be solved by changing the battery.
I'm sorry that it has taken a long time to find - but we actually note the issues people write about and we'll send it on.
Sometimes it takes a little longer for Huawei's developer and test department to find the error.
Everything indicates that your phone should work exactly as desired if it changes the battery.
I would recommend telling Telenor or Care1 that it is a message from Huawei's technical department.
So in general i am not done with this case .... but i felt like this was information that might help anyone else in here that have the same issue with their Huawei P9 phone and dont know what to do about it, and could use this information that i have from Huawei via their facebook support.
Again my little "adventure with a phone i cannot use out doors" and Huawei support.
Small update:
Huawei here in Denmark cannot say witch models of the P9 that have this issue but they confirmed to me over the phone, that within the last 24 hours they did receive information in their support department here that there is an issue with some of the Huawei P9 batteries and where this will result in that some phones will shutdown when getting cold and this is also when in temperatures above 0 degrees celsius after short time of use, no matter the level of charge there is on the battery beforehand
so now for the 4th. time, my P9 is in for repairs .. Hope they get it right this time.
Bummer, man, no doubt. Hope you get it sorted soon.
I, on the other hand have no such issues. Temperatures here have been oscillating around 0 Celsius for about 2 months. I spend lots of time outdoors and the battery drain is just the same as it is indoors.
I had a similar problem. I was outdoors taking pictures of the first snow and keeping the phone all time out or in the outer pocket . It was about -3 Celsius and after two hours phone shut down displaying that battery was empty. When I went back indors, to warm, I switched the phone and the battery was still 65% full.
Later, I spent a weekend skiing, but keeping the phone under the jacket (pulling it out when needed), and didn't have problems with battery.
Same here. Went skiing and P9 will shut down due too cold, especially when the battery was lower than 50-60%.
To be honest I thought it was normal as the iPhone of a friend of mine behaved the same: it turned itself off due to the temperature (-10°C).
I managed to continue keep it alive by putting it under the jacket and not keeping it out too much while taking pictures.
I would not complain for -10 C, I think no phone will work. But my experience was on -3 C, I was with my wife and her older phone (with older battery) Galaxy worked just fine, even less charged than mine P9, under the similar conditions (holding in hand, taking pictures)
Its really common, mostly in iPhones and LG, but every device can behave like that in -10C conditions. Especially phones with metal backs that are not protected by user from such harsh environment(because if you live in such cold place cheap rubber case is useless).
I would not call it a major problem, especially when manual it self clearly say that minimum temperature that you can use phone is 0*C
But dont look at number it self, thermometer can show 0, but because of humidity of air, any electronic even at 0*C can behave like it is less than that.
And because metal body and getting phone out from pocket to cold air few times its a matter of minutes when the moisture will gather inside and phone will shutdown preventing from damaging it permanently.
I know that there are other things that could be stated as "major problems"
But i will however still say its somewhat of a problem as a phone that is less that a year old cant hold a charge for approx 30min even when at 100% charge when going out the door and this is even when its in a cover and is either in ones hand or jacket pocket and this is even in temperature that is between 0 degrees celsius and +8 degrees celsius.
But still i have taken me around 2-3 months to get Huawei to finally say ok there is an issue with the batteries in some of the P9 models and if you have this issue with the phone shutting down you should get the battery changed
I have also several times requested Huawei to share the information they have on the batteries, but i guess you all knows who hard it is to get a manufacture to release that kind of information to the public, so no luck there.
First of all, many thanks to you -> freetechdk ...
But, what happens now?! Do you, or will you get a new battery, paid by Huawei?
We do have, sort of the same Problem... Unfortunately it is getting worse rapidly ...
My wife has is p9 and was happy so far... just about 2 or 3 months ago, the battery was getting worse. It hasnt shown the effects it does now, but was getting drained very fast (she had to charge nearly twice a day, which, i know, depends on your own usage, i know... but..., twice a day...) Then, just about a week ago, she dropped it that hard, the display was smashed... So we had to change display, what happened last tuesday. Since then however, the phone is reacting very strangely! We now have exactly the same effect as described by you! 70% full battery, went outside at about 3°C and the battery was at 1% and the phone shuts itself down... Somehow i am relieved that it seems to be the battery... why?! Because, very carelessly we handed out the screen-lock to the guy who changed the display... i really wasnt thinking, because my wife and baby have been waiting in the car, in the cold (because the littleone was sleeping). just when i came back to the car, i thought "what the *** have i done" :-O ... and praying, he would do nothing bad... then, when we got the phone back, it was reacting strangely so my first thougth was ?! Spyware ... We are not sure, maybe it is "poisoned", but the battery thing seems to be a legit reason for the phone racting this way... So, we might try to change the batt... (and are still praying, for no spyware ... by the way, does anybody know how we can check this?! I tried (from ggl play):
antispycell.free
arcane.incognito
cleanmaster.security.stubborntrjkiller
and have all been negative so far... also i have been looking through processes and, i dont think anything to be fishy there as well... Anyhow, any hints would be appreciated!
Sorry for off-topic question

So had a talk with the repair shop that Huawei said i had to use due to warranty and so on, also the place the phone is now and they will change the battery as a warranty case.
The other main issue in all of this is that this is the now the 4th time that the phone is in for repairs with this issue and the repair shop have also previously changed the main board of the phone, so by no i really have no faith in the phone even if huawei now claims that this will fix the issue.
So after pleading my case to the repair shop and had them contact huawei and convince them to call me so we can sort this out, they will not see if they can do something else for me than just trying to fix my phone for the 4th. time with in a year.
So nothing is set in stone right now but looks to that huawei is swapping out my phone to a new P9 or something newer.
But this was all just because my tele service provider that sold me the phone had failed several times when trying to get them to fix it and then have a ton of issues getting huawei to take my problem seriously over for the last 2-3 months.
But when i talked to the person from huawei he did tell me that the battery issue for the P9 is something that they only found out was an issue with in the last week of Jan. 2018.
so if you have a P9 that have issues with holding a charge in semi cold weather / environment i recommend you contact huawei about the issue and have them swap the battery, but this all depends on the warranty rules in your country, here in Denmark these rules / laws are really good and does provide a descent level of aid to customers that have a defective product.
I used the support chat they had on their facebook page, the support there is not great but you do in some way get semi direct contact to huawei.
Just yesterday i contacted Huawei. After asking for IMEI and Build-Nr they told me that more or less, this is a Battery issue due to high power consumption because of the temperatur and advice me to
only use the Phone in enough warm environment

Are you f***in kidding me :cyclops: ... what do i have a mobile-phone for, when i am not able to use it??!??!
Well my exact reaction when i first talked to Huawei about all this ... !! stupic to have a phone you only can use when your indoor or in a warm climate.
But Huawei here said that mine phone where one of those that needed a battery change... well they did this, but would guess that the repair shop did something wrong because when i got it back it did random reboots all the time..
4 times while trying to set it up again after the battery change.
Sooo a rep. from Huawei's service deparment called me last week and asked if i would send it back in and have it swapped out for a new Huawei P10, well OK with me, BUT IT BETTER NOT be the rose gold version they are gonna send back to me.
Hope you get through to huawei and get them to fix your phone!!
OK so the Huawei P9 battery issue came to a close for me.
Huawei gave me a new Huawei P10 as a replacement for the broken P9 i had
But still from my point of view some P9s for sure have a battery issue that Huawei should do something about and i would recommend all that have this kind of battery issues to contact Huawei and try to convince them to change the battery in their phone.
Hey guys, thank you so much for making me aware of this!
I sent in my phone for repair because it was losing 1% battery every 1 min (and that with a lot of battery saving tweaks already) on a day we had -5°C.
And it automatically shutdown in between, rebooting showed 1%, so I went to a repair shop by the provider and suddenly charging it turned on with 56% battery ... and then me and the repair inspector (they inspect the phone, if it is a very quick fix they do it, but otherwise they send it in) we saw mentioned 1% per 1 min together and so we sent it in.
I originally went into the store because suddenly the SD Card & Sim were failing. Guess what, charging the phone in the warm store/repair shop and it worked again FLAWLESSLY.
Any advice what I should write Huawei when I get back the phone and it still happens? I mean it has still warranty, so that must fall under it.
Mine does this as well, shuts down on heavy use on sub zero temperatures , but it's normal that after 2 years the battery would be on the end of it's life cycle ...
I kinda see improvements on battery with MR4 to be honest. Not while it's cold tho. We had some - 20oC here till last week so phone was shutting instantly when it was not in my pocket. Definitely I can tell you that battery lasts more but I use Facebook Lite, messenger Lite and everything else is deactivated from running in the background. I get like 35 hours standby otherwise with heavy usage 6-7 hours. If you wanna try Magisck rainbow 4 please do a clean install after at least c432b395 version
I have the same problem, so now I can tell the tech what the problem probably is. Thank you
-Fellow Scandinavian
Same problem here with my gf's P9. Just started to occur this January. Good to know it's somewhat acknowledged by Huawei. I just hope I can find the receipt (she got it as a gift from her parents...).
