Hey everyone
I'm usually super careful when it comes to my smartphone and battery health, I only charge it as slow as possible and try to limit charges over 80% or under 30% as much as possible.
However last weekend I left my phone in the car by accident. Of all things I chose one of the hottest days this year so far, the car was standing in the blasting heat for a couple of hours. After getting back I kind of panicked when I noticed that I had left the phone in the car, it was very very hot. In this state of panic I immediately turned it on (I know I shouldn't have). The device booted up normally, however the touchscreen seemed to be less responsive than usual.
Now I kind of fear that I ruined my battery's health. Subjectively it seems like I need to recharge the phone sooner. Is there any way to tell how much damage I did to the battery?
Thanks for the advice!

well when i first got my phone i only charged it when the battery light was red and hollow. And at times i would put it under my pillow due to the alarm being so loud, didnt want to wake up my son.
But the past few days when i charge it and put it under my pillow it gets really warm, it never did this before, any reason why?
AFAIK all phones do, as well as any battery you charge (MP3 players, laptops, etc).
yea I agree, I think that is something most smartphones do, my mytouch did it... so did the g1
Thats because it charges at 1000mA via AC.
Don't charge it under your pillow! definitely not good for it.
Today I charged for an hour my n1 over usb.
It was really hot.
Then I go to home, and when I arrived, it was again really hot, and battery life is over.
So I reboot and now is ok, but is very very strange...
yeah they get hot, i have the battery life widget and also shows the battery temperature, when it was charging it peaked to 110 degrees lol
I came from a mytouch 3g, didnt have it long, i love Android, i guess i change the alert to something more calm. But before i charged it under my pillow and it never got hot. Maybe its a wear and tear thing
Any device to which you're pumping power into, or using power, generates heat. That's how it works. The only difference between the devices is how much it draws; the more it draws, the hotter it gets.
Yep. Don't charge under your pillow. It needs air or it will get super hot. Not a good thing.
Man...I thought my N1 was going to burst into flames today. 114.5 degrees...not sure if it would have gone any higher.
I was in the car using an AC/DC adapter. Had my navigation going along with my music. The glass on the phone got hot to the touch! I unplugged it right away.
How high of a temp can this phone endure without damage? If it were to overheat, would it just freeze up and shutdown?
Anyway...what's really weird is that the phone was plugged in when battery life was at 80...when before I unplugged...it was at 79. Huh?
warm nexus!
i charged my nexus tru the usb a few days ago, yes it got warm like always but when it was fully charged. it stayed warm even when it was unplugged from the usb. i know that was kinda odd and it drained the battery, it was at 76% just after 30mins. so i reboot and everything went back to normal. what the hell?! i think its a bug. what i do now just to be safe is i reboot the nexus after every charge and check if it stays warm...
So I was charging my phone last night and it was under my pillow on airplane mode as usual, because I use it to track my sleep patterns. But this morning I woke up phone was off, with the charging battery icon showing only, and was so hot to the touch I literally couldn't even pick up the phone. I was really surprised it didn't melt or start a fire, that's how hot it was.
Now today after letting the phone cool down, it doesn't seem to be taking charge well at all, I'm having a very hard time getting past 25%, if I use the device while charging it will actually drop charge while in use (and this is with the wall charger).
I'm thinking the battery cells have been damaged by extreme heat. but just wondering if anybody else had the phone get this hot?
Sounds like damage to me! Sorry to hear that man.
Also seems like an irreversible damage to me :/
Some day I accidentaly left my LG GT540 letting it charge under my pillow. It got EXTREMELY hot and I unplugged it swiftly; I was so frightened that the battery (Li-Ion!) might have literally blown up.
To be honest, you should be grateful that your pillow didn't catch on fire together with your head, really... NEVER EVER LEAVE YOUR PHONE CHARGING UNDER ANY PILLOWS!
Well guys funny thing is, seems to be charging ok now.
I believe I'm having a similar problem that a lot of other people are having with the phone getting stuck on USB charging mode even with the wall adapter, so not accepting ACpower. But once I reconnected it a few times now its charing on AC and got back up towards 70%, so I think luckily I might be ok.
But damn this phone gets so much hotter than the galaxy nexus.
My phone never gets hot when charging...ever. I think you might have an issue with your phone
My phone has serious temperature problems... If I surf in the internet and Facebook then my S4 is almost always at 40°C . When playing games then it can reach over 60°C (where the CPU is under the screen, measured with optical IR thermometer) It randomly starts heating up in my pocket till it is so hot that I cant hold it in there anymore.
Battery life is around 8 hours with LIGHT use!
I bought my S4 on first may and that problem appeared after summer holiday.
In November I sent it to warranty, It took them like 20 days and they did basically nothing to it. I haven't had any time to send it back there because I need my phone.
Yesterday I put it in a warm glove mining Dogecoins using AndroMine (android CPU/GPUminer) with charger connected
After 15 minutes it was at 67°C and battery was down to 30% form 97%. About 5 minutes later I heard a vibration, it had turned off and it didn't boot anymore. I was very happy, because I thought I manged to burn it down. Unfortunately it booted after cooling down . Now the battery life is even worse...
I'm thinking of putting it mining in oven... oven at 50°C I know that S4 has temperature protections but sill it might work. And the battery inside definitely doesn't like heat, so it might pop .
If I mange to burn it then I will get warranty replacement!
All crazy ideas to burn it down are welcome !!!
Sounds like a defective battery. See this thread

The thing is that my battery serial is YS1D420JS/2-B
And how can defective battery make phone become hotter?
As the title says, Phone won't turn on. There are no led lights at all. It does get warm after being plugged in for a little. I had jrkruse's hybrid_bra1 stock safetynet samsungpay...... rom on it. It was rooted. Very minimal processes running. I actually had basically everything stopped and greenify on. Phone was around 40% battery. I plugged it into charger, took my dog outside, showered real fast, washed a few dishes, then came back in to room within 15 minutes to my phone being dead and hot. It's never got this hot before even while rooted and plugged in with this rom on it. I have never had it get that hot. Was just formatted the day before and really bare but, that is what happened.
A couple battery apps I had put the batteries remaining life capacity at around 60%. It held a charge poorly. Even for 60% capacity it felt weak, considering how little I did on it lately. I am thinking the battery may have took a crap but unsure because it warms up when it is plugged in. I plan on getting a battery soon since they are inexpensive and replace it to try it out.
Just wondering if anyone here has any experience with this and can offer any advice.
Thank you in advance.

You say your battery was already outworn, It may have died. I think you should try with a new battery, Or take it to a technician who can test the phone's hardware to see if there is anything else broken
i've only had one similar case with an s3, which would turn of at random % of battery. But when plugged turned on. I replaced the battery and it worked fine then

I really do hope that is what's wrong. I just ordered a battery. Thanks for the reply. I also got some little tools and battery door adhesive sticker. Wish me luck!
funny story....
The mic in my Nubia Red Magic broke and I sent that back to hong kong for repairs like 20 days ago. Before the Red Magic, I used this galaxy s7 edge my friend gave me. I gave it back when I got the Red Magic and told him to sell it or something. Not much later, decided to buy it back off of him for $200 to give to my mother. She loved it. I had the gs7 edge with me exploring prepaid provider options for my mom when the Red Magic mic broke. So then I decided to borrow the edge from her till my phone got back and few days later I break this one too..
I feel naked without a phone for so long haha

I have the same rom, with charging issues. I don't think its the rom causing it. The s7e are getting old and the batteries are taking a toll with the age. My phone will charge up to 81 at night and stay there. I get better results with wireless charging so i just top my phone off during the day with my wireless charger. There is a code to reset the battery's internal memory, if i find the link on how to do it I will post here for you.

Thanks for reply and alright let me know if you find out. My phone had no problem charging to 100% Its just the 100% on the status bar wasnt 100% of the 3600 capacity from wear. My friend's also does the same thing as yours except his he cant charge more than like 24% haha. He just uses it as a plugged in music player in car.... I am getting battery in the mail tomorrow and will see what I can do.

I have not done it because it requires draining the battery and I never get around to doing that. Hopefully it will help you out. Good luck!

A little late, sorry. lol.
Thanks for suggestion, however, I may have worded my statement incorrectly. I meant to say that My phone would charge to 100% and the status bar displayed it as 100% but, the health and total capacity of the battery in mah was not the maximum 3600 or so due to simple wear and tare. It isn't apparent within any stock android feature however, battery monitoring apps like accubattery gather statistics after several charging sessions and estimate the current mah capacity. Mine was much lower than the default oem stated value of 3600. So my battery could be charged 100% but the 100% is really only 2400 mah lol. It was obvious either way by noticing that after my time using it and the previous owner's bad charging over night habits, that the battery was gradually needing charged more often lol..
I did read about the calibration method before when I was first looking into the battery issues. It seems it is more often done after a new battery is installed.
I screwed up a new battery install at the last second. I had to stop due the tiniest little round metal piece coming off from a very light swipe of my plastic spudger.
It was a very small wire connector piece. Unbelievably irritating. I didn't even finish because I doubt it would work properly. I beleive it is for the rf cable or something not sure. The red one on the left bottom side of the logicboard/motherboard whatever. There are three of them.
I took it apart and put it together a couple times prior to this and in a hurry it popped off and I couldnt find it. I couldnt find out the exact part name online so I could buy one and solder it back on. I did find a site/ supplier that has a plethora of them though. They are tiny coaxial connectors/pins. I didn't look through them all but there are 6,000 some listed under coaxial connectors (RF). https://www.digikey.com/products/en/connectors-interconnects/coaxial-connectors-rf/437?k=coaxial pin
I haven't gotten around to asking samsung or the digikeys support if they could help me find out which it is. They have different sizes and frequency ratings or speeds and such. The phone is packed away until I manage to figure out which pin to buy or if I pull 80$ or so out of my behind and buy a whole new motherboard logic board haha.
Hi, I usually leave my phone under my pillow overnight, I know it's not the best idea, but I have being doing this since I have a smartphone.
The problem is that when I wake up my phone is very very hot.
Just to clarify I don't charge my phone overnight, I know that generates heat.
A phone doing nothing should not generate heat, I am very dissatisfied with that
So you think my phone is faulty? Do this happens to you?
Inappropriate post removed
Well, mine does heat up too when I play games or charge it. If you bought it new, expect it to get slightly more hot during charging for first few days.. atleast thats what happens to me. After few days, software updates etc your phone should not heat so much that you cant hold it in your hand. Also, the phone is made up of glass and metal so it does feels more warm than lower end devices like A50, A7 etc
