cold battery

Im skiing with my titan and the battery doesnt get along with the cold. it just gets completely drained everytime i turn it on, and as soon as i go back in and plug it in or let it warm up it shows like ~60% left.
anyone have any ideas or suggestions about what i can do about this?
i know its not a problem with the phone and is just the nature of batteries, but im looking for some suggestions that others might have.
thanks

Could your battery be draining faster because your phone is searching for the best signal. The Q that I had would drain the battery quicker when going from EV to 1x signal.

i dont think so, even if i leave the phone off, then turn it on when its cold, the battery drains really fast. like a minute or two till i get a low battery warning

Maybe get one of those 8hr hand warmer packets and put it in the pocket you keep the phone in...although we went tobogganing for 6 hrs in 20 degree weather and my seidio 3500maH didnt budge on my mogul without any heat.

No ideas, but I also experienced a very fast battery drain this morning when I was outside shoveling snow. I had about 60% when I started, I was outside for 1.5 hours at -5F. I have the phone in a holster on my belt under my coat. When I came in, the phone was in an alert state at less than 5%. It was cold to the touch. This battery is just over one year old and is my best one. It is a Seidio 1650mAh.
I have not seen this before, but I should have more chances to repeat the experiment before this winter is over.

LiOn batteries don't like extreme cold. I use cordless drills with LiOn batteries and I get the same thing when I leave them in my truck. I will go to use them and maybe get one screw or hole drilled. If I leave them warm up they are almost full charge as the charger only takes 5-10 mins to charge them. I suggest to maybe take the battery out and put it in your pocket inside your pants. It should stay quite warm there!!!

Did I fry my S7 Edges battery?

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!

only heats up. doesnt charge

Hi
One of my S4's, i9505 variant, has stopped charging out of the bloom. Batteries that recognise as 50% full on my functioning S4 identify as 0-2% on this broken one. In stead of charging, it gets extremely hot and shuts off the charging screen due to this.... But continues heating. Because the screen is broken as I use it as a spare battery charger, I swapped the main boarded into my working phone to see what is on screen. And it almost cooked my good screen :laugh:.
Does anyone know this issue or how to fix it?

It's not worth fixing. The motherboard itself needs to be replaced.

Alright thanks. Was hoping to save it as I use it to charge my spare battery. Was so useful. R.I.P

My battery can reach 41c while charging and intensive use usually and feels warm to the touch. But when I left it in the dodgy phone it felt a bit hotter. I'd say 10c hotter as a guess. Would that damage my battery? It was sitting plugged in for about an hour at most and probably wasn't charging much. (The battery was the coolest part of the phone yikes)
The top of the phone was too hot to touch at all. Battery felt about as hot as my normal S4 gets under med use. Toasty but not untouchable.

Heat is never good for a lithium ion battery as the materials that make up the battery degrade as a result. That said, 10 degrees warmer isn't going to affect the battery enough to kill it. The motherboard itself likely developed a fault that killed its charging circuit. You should be thankful the battery didn't get a power surge from the fault, or you'd have set your broken device and whatever it touched on fire as the battery exploded.

Won't turn on, no lights, but warms up when plugged in.

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.

phone overheats overnight?

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
