I recently started watching the battery temperature on my Verizon SMT5800 phone, and was surprised at how hot the battery got while charging. It has reported internal temperatures as high as 210 degrees Celsius (410 degrees Fahrenheit) while charging. Some documents that I have found on the Web suggest that this indicates that the battery is being overcharged. The battery becomes merely warm to the touch, which might mean that the internal temperature is not as high as reported, or might simply mean that it is well-insulated. What sort of battery temperatures are normal for Lithium Ion batteries?
mine just 35-45 degree celcius
mine htc p3600i
I suspect that the battery's internal sensor may be reporting a higher temperature than is actually present. I talked to Verizon tech support, and they told me to bring the phone by a Verizon store so that they can test the battery. I plan to do so.

The temperature as reported by you of 210 degrees centigrade would certainly melt your device down. The temperature you saw is full of flaw in the application, it can't be true anyway.
I have now tried two other batteries, with similar readings. While it is possible that all three batteries had faulty sensors, it seems more likely that the battery interface isn't standardized across manufacturers, and the data is being misinterpreted. The two applications that I have been using to retrieve the temperature, SBSH Facade and Accosto BLifePlug, are both general Smartphone applications, not HTC-specific.
My battery temp currently reads 3 degrees C. I quit really paying Arthur to it day one. It always reads slightly above freezing.
I don't find a need to check battery temperature. Moreover, phone/battery tend to become warmer when its charging.

I know, that can already melt metal right? 210 degree C?

I don't really check exact temperatures. If it feels unusually warm (pretty only if I'm tethering and charging simultaneously) I prop it up in front of my desk fan. Otherwise I don't really worry about it. Batteries are made to withstand a good amount above/below normal operating temperatures.
In my xperia mini pro, reaching around 31 º Celsius
I can't believe it,maybe there's something wrong with your battery!

So is mine! It has been like that since I started using custom roms (with no or hardly any overclocking). I think it was lower on stock. Which rom are you using?
It reaches about 30º on HTC desire.
But not on Sumsung moment using now.
I got the temp light only once when I first got the captivate. I was downloading a lot of you tube with a dead batt and charging
I have an issue on my HTC desire as the battery gives me constant values:
- battery voltage: 3923 mV
- battery temperature: 24.3 deg Celsius
- Current:
* either constant to 8mA (after a full charge the current says 8mA for some hours if phone is in standby)
* or constant to 44mA (whatever I do, playing games, browsing, watching movies..., or doing nothing)
Those values can be obtained with the secret menu (*#*#4636#*#*), using the apps "Battery Monitor widget" and CurrentWidget, or from kernel logs (cat /proc/kmsg in terminal emulator).
Apart from that my phone behavior seems to be normal, and the power consumption seems ok.
For some it might not be a big issue but, as I am trying some ROMs and different kernels, I would like to get the real current used (in mA) in order to really test the power consumption.
I did already did some tests to understand where the issue come from:
- full wipe (cache, data, dalvik) to get a clean ROM
- try a different battery (battery reference are both 35H00132-06M)
- change ROM and kernel
but I always get the same values !
That's why I suspect the issue to come from the battery sensor.
Now here come my questions:
1- Did any of you already had such an issue ?
2- Is the Battery Current sensor and Temperature sensor are the same one ?
3- Where are located those sensors ? In the phone or the battery ?
4- Do you think this wrong values could lead to strange phone behavior or damage the battery ?
Thanks for reading this boring post and even more thanks if you have some answers !
If the battery is being used in the same way as another battery then the results will be the same. If your getting 44mA from using your phone then good. Power consumption is low. By turning the screen on and not doing anything, I get to about 120mA. To be honest, this just seems normal, nothing wrong here. Unless I am missing something everything is fine.
My problem is that every returned value is a constant, I don't see any changes in terms of current if my screen is off (even in airplane mode, nothing running) or if I play a game.
I still get the same current, voltage and temperature values. That's why I suspect the sensors not to work.
Now I would like to know where are located those sensors (in battery or in phone) and if this sensor issue could lead to potential problem... I suspect it could damage the battery.
Anyway thanks for your answer, regarding your 120mA with screen on is it a normal value ? how long does you phone lasts on a battery cycle using CM7 ?
Testing the sensor
mmh, my question does not seem to passionate lots of people
I have a new element, I installed the apps called z-DeviceTest and Temperature sensor is said to be not working.
Is there anyone who could try this app on his HTC desire and see if the problem comes from the app or from my phone.
Once again if someone could answer the following questions, it would be quite helpful for me:
Is the Battery Current sensor and Temperature sensor are the same one? and where are located those sensors ? In the phone or the battery ?
problem solved !
I went to the shop where I had bought phone and batteries and I made some tests together with the reseller using Battery Widget Monitor. It has been easy to find out that the issue was coming from the battery.
Actually I was unlucky, I had bought 2 defective batts ! Or at least the battery sensor was defective. The batteries seemed to work fine but because the sensor was broken I think that after some charge-discharge cycles the batteries might have been broken.
So in case you have such a problem, just try another battery.

damn it, it happened to my battery as well.
I have experienced the same problem and reach similar conclusions.
More details are given on my blog 78michel.unblog.fr
Looking more in detail to this battery caracteristics, I am now anxious about one point:
You observed , and I confirm :the temperature is always at the same level.
Looking more deeply at safety IC for LI-Ion battery , it seems that the NTC which normaly gives the temperature of the battery has also a safety component which prevent from extra heating and fire.
If the temperature is constant , may be it is beacause the NTC have been replaced by a resitor. This means that there is no longer any safety system active!!!!!
I am trying to check this point.
I have the same problems as mentioned above. Always constant 3923 V and constant mA drain.
I have bought 3 batteries from different sources all have the same problems
2 batteries have the S/N 35H00132-06M and 1 with S/N 35H00132-01M
The only battery that is working is the one that was shipped with my phone.

i have the same problem with voltage indicator - 3923 mv even my phone is low on power or fully charged!
strange issue....
someone did find any answers till now?
i'm try'ing to change my rom from cm7 (7201) where i am now to another rom to see if problem persist.
i'll be back with some conclusions...soon!
I'm seeing the same issue with 2 bilitong gold batteries. Despite them claiming to be 1650mAh they test at little more than half that with jumps in the % left reported rather than a smooth reduction The batteries appear to be 'genuine' bilitong batteries as they arrived in the blt packaging and not just a battery with a lable.
They also only charge to 99% and the charge light stays orange when powered on although the charge light goes green when its switched off and charged
I would surmise that these effects are seen from batteries which are trying to hide what they actually are. aka the manufacturers disable, or more likely do not include the protection circuitry which
* reduces the cost of manufacture
* decreases the losses through the battery as there is less control electronics to power/incur resistance losses
* prevent reporting of what the battery state is and is doing hence indicate its true capacity.
this would also explain why some folk say that a battery melted/damaged their phones.
Unfortunatly there are a lot of 3rd party batteries for the Desire who have bugged electronics inside.
I tried several 3rd party batteries before ending up with an original HTC battery, that works fine.
It seems like all those companies just buy the same electronics, assemble it with the cells and case and put their name on it. (polar cells, andida, etc.). They maybe check the values once, and because they seem legit, they think it is ok.
Im afraid those electronics are a big intended fraud, because the output seems made up to not be perceived so easily...
Unfortunatly sellers and manufacturers seem dont really care about their broken products, because most people just buy them and dont check for sensors or dont give a ...
But I do see some serious risk here, as others pointed out before:
if the temperature reported is always 24°C , the device would not switch off loading when the battery starts overheating, like it would normally do. IMHO this could lead to serious damage to the battery, device and surrounding.
If you get one of those batteries, I strongly recommend to get your money back.

Agree fully, especially regarding the overheating, which also likely means the CE labeling is false or at least unjustified outside of any tested ones.
Temp reported at 24.x even when phone is hot.
Mv always reported at 3923
Claims 1650mAh (or anything from 1500mAh up to 3500mAh in other Chinese batteries) but shows between 2-3 times the power drain of a old original battery (@ about 1100-1200mAh of original 1400mAh) whether under load or in standby if battery power set to 1650 in monitor utility, which means they are probably only about 750mAh real capacity at best under normal load.
I see when searching that shenzhen Himax (presumably not to be confused with Himax tw) seems to make some bilitong brand batteries, but there does appear to be a separate shenzhen bilitong unit/factory in poison province China (shenzhen, Guangdong Province).
Its quite likely the companies are related, and they may well be the sources for many if not most of these crap batteries. Its notable that these 'branded' bilitongs despite their very pretty and professional looking packaging had nothing on them stating a capacity rating, so anything could be claimed.
Pretty packaging wrapping a turd..
Happy to revoke this view if I am given any verifiable evidence (preferably me testing) to do so.
Just testing a bxt (baixt) claimed 1600mAh blue coloured battery which seems OK at least. (NOTE - not the gold coloured bxt with ridiculous 2450mAh claims).
Voltage seems to be reported OK although temp is wildly inaccurate in the one I have.
Seems to be testing roughly 1000-1200mAh with low standbye drain
So seems very OK at the price
Note this is testing on my backup zte blade/san fransisco where the standard batteries are lower capacity than on the HTC desire:
(1250 vs 1400)
people please help any way you can. my battery is all messed up. with each calibration I make it is worse. nothing helps. I tried with various ROMs and kernels. The problems started when I was at Supernova and not in the beginning but after few months of using it. I put GingerVillain and immediately calibrated. Phone was charging overnight, I plugged it off at 9 am and he died at 9:10 at about 90%
*
and all the time it dies at about 85-90 %.
*
For each calibration shows me that it was successful.. Chgtf is lit and value is 0x81. After each calibration in my batery batery calibrator shows age 50%.
*
I noticed that when the battery is at 0, it charges about up to some 20% and then immediately jumps to 100 and the indicator lights green.
Is it possible that the battery is bricked or something else?
Any help???
Cheers
i think the calibration is last thing what you can do when battery is aged.
i bought this battery http://www.ebay.com/itm/390392595398?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 and this seems to be good.
Yes and evaluate when you buy a new battery, because i experienced problems with amazon/ebay sellers which traded fake batteries(a lot less capacity as shown), but looked like a original http://forum.xda-developers.com/showthread.php?t=2457104

I'll +1 that.
A new battery solved simlar problems for me (though by far not as bad as you've discribed)
Hi my friend
I wonder if unoriginal battery can cause bad performance and high temperature?
I think it can definitely cause high temperature but what about performance?
Do you think bad battery can cause bad performance? Most LAG, maybe freeze also
My Xperia ZL has unoriginal battery and it gets very hot in summer, sometimes I feel very bad feeling in hands while holding it, it's like electricity running all the time on it's rear cover...
very hot in summer, the screen and the back also.
If its a bad battery of course it can bring high temperature, i brought a 3rd party battery for me, it fells more cooler than before, but i not tested it to much, cause i'm selling the phone to a friend and he is testing it, the only annoying thing is the standby, it keeps decreasing juice a lot, will try some roms to see what i can get.
Hi, I'm having this battery
http://www.shopclues.com/original-mobile-battery-for-l35-for-sony-xperia-zl-l35h-2330-mah.html
it's expected to be original, but my friend who deals with repairing of mobiles, said it is not, but it's still a good quality battery
costed me like $16
it does work for one full day if I use for songs, phone call, and little bit networking
it surely does not last like original, but this works, and I'm not disappointed with this purchase
just look for original battery at sony service center, or get from online retailer, some google, that can lead you to original battery seller
about your questions:
on this battery, I was playing kingdom rush when it was 90% hope so battery lasted for an hour
and max temp was 36 c for me
but yes, I have greenify, and all bull**** was stopped on my RR 7.1.2 ROM
A battery can give bad performance, if it has bad build quality, so just try to get from good source
In the beginning, a bad battery will usually drain faster like 50...40...30...20... OFF, no shutdown, just deadly off, that's a sign, to protect your mobile from hardware based damage, and also software
just make sure you use an app that provides tickle charging, that helps battery last longer, refrain from bad charging behaviour like, don't keep in charge at 60%, wait for it to be near 25%, and do a full charge
follow good charging habits, and remove unnecessary stuff to prevent drainage
and you would be good to go
Hello...
I've decided to try to replace a battery in my HTC One M9. I finished it about an hour ago and fortunately everything is working so far but...
I've noticed some strange battery temperature reading. When I'm charging the battery, it shows 25C all the time which can't be true, cause even the case is a little warmer. If I unplug the charger the temperature shown by the software rises immediately to about 35-36C, which is more possible at that time.
And again, if I plug the charger back to the phone, the sensor stuck at 25C.
I'm not sure where could be the problem, is it something wrong with the temperature sensor (I'm not sure if it's builtin into the battery itself) or could it be something wrong with the new battery? Battery is actually charging without a problem, but I'm a little worried about overheating (especially using the gps in the car).
I'd be grateful for any advice
How are you checking the temperature?.
Is the battery an OEM or cheap copy?.
My battery was replaced recently and it is charging fine but acting strange too.
Generally I use 3C Battery Monitor Pro but all other software shows the same readings with this battery - if it's plugged in it shows around 25C, if it's unplugged it's a little more interesting, because when the battery is cooler it shows around 37-38C and when it gets hotter it even drops to 32-33, so now I'm sure there's something wrong with the sensor (I think it's build it).
Speaking about the battery itself - the seller claimed that the battery is original, it also looks like a genuine one, but I have my doubts. First of all it is slightly smaller that my original battery, and now that situation with the temperature makes me think that it may be a fake one.
Anyway... I'll try to return it to the seller and order something I'll be sure is a genuine one. For now I'm waiting for the seller to reply, I hope he won't make any problems with the refund.
Before making any commitments try the app "system panel 2" from playstore. I had best results across the functions with that. 3c caused allsorts of problems for me in the past.
I've been using 3c for quite a long time, never had any problems with it (both 3c system tuner pro and battery monitor pro).
I've also tried system panel 2, but as I mentioned in a previous post - all other software also shows wrong temperature readings. With the old battery all software (including 3c) showed accurate readings, so it's definitely something wrong now.
Compare it to the other temperatures. This stock unviolated phone i have in my hand while typing for the last 30 mins or so is at 37c on the battery and 39c on the cpu, 38c on all other sensors.
My previously violated phone which had a battery replacement, just sat doing nothing but being a phone, is at 34c battery and 41c cpu, others temp sensors range from 27c to 34c.
Systempanel 2 is where i got the temps from.
If you're running nougat try an app by htc called boost+. It really does help a lot for those apps that keep running in the background.
I've also check other temperatures, but it's actually doesn't matter in this situation.
Other temperatures are shown accurately (CPU etc.), the only problem is with the battery temperature. First of all it shows incorrect reading (shows higher temperature when the phone is cooler, and lower when the phone is warmer) and more importantly as soon as I connect it to the charger or to the computer temperature reading suddenly drops to 25C, even though the phone is still warm, and actually is warming even more during the charging. Also when I unplug the phone it immediately rises to 37C.
I have also replaced my battery with one from eBay that the seller claimed was OEM, which in fact is not.
It has the same behaviour as yours. 25 celsius when charging, 35-38 when idle or heavy use.

Thanks for the info. Do you still using it, or did you replace it?
I think I'll try to change mine to the original. I'm worried especially about charging this one in the car. I know that sometimes using the navigation and charging, my old battery could easily reach 40C and more, so it could be dangerous with wrong temp readings.

I am using it from like a month. It's not heating up as much as the old one (which was 2 years old), but still gives me the same SoT - 2-2:30h. Recently I began concerning a little about the 810 heat and the fact the battery is not genuine.
I also screwed a little my back camera when replacing it, so I'm wondering now if I should try to sell it or get an original battery, but if I were in your situation, I'd probably try to find a genuine battery.
Notice how your old one's labels look far more crisp and with better print quality. There's also a barcode on the battery. I think these will be the things I'll be looking for if I go for a battery.
Just out of curiousity, what SoT are you getting before and after?

Yea... I think I'll do like you say. I've already found a seller which has (probably) a genuine battery, at least if the photo is real.
About SoT, it's hard to tell, I've replaced the battery yesterday (or the day before it). For now I only charged it, and checked at what percentage it will shut down the phone (with the old one sometimes my phone was dying at 20%). So I haven't checked any stats yet.

I see.
Be careful when buying the battery, because sellers are lying about being OEM and the image could be fake. You could ask for a real photo or something.
Also about the temperature sensor, I think the reports are coming from the battery itself.
Cheers
Just for the record, I've returned the fake battery and bought one from another seller.
In the beginning I was a little worried, the photo actually was a little different from the product I received - on the photo there was a bar code, but on the battery that I received is QR code and some other production dates. Also there is a little different product number - last 3 letters/numbers are 04m instead of 01m which look like it's actually for M8, but looks like it's compatible.
Anyway... The battery look like it's genuine, works without any problems for about 2 weeks now, it shows real temperatures. It looks like it has capacity as described and first of all - it's perfectly the same size and alignments as the original (which was actually pretty far from perfect in the fake one).
Can you please tell where you bought that genuine one?
Hey and sorry for the delay.
Actually, I don't think it'll help you. I bought the battery from some local seller on Allegro (it's an ebay like service). And just for the record, the battery still works fine
