only heats up. doesnt charge - Galaxy S 4 Q&A, Help & Troubleshooting

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.

[Q] Battery Preservation

Dear L2 G2 owners,
I really love my battery on my LG G2 and since its not removable i want to do the best to preserve its lifespan.
So what i'm doing is, plugging in my phone to the charger when i get home and leave it there even after its been completely charged.
Is that correct or should i leave the battery to complete its cycle then charge it when its almost empty.
What other tips would you suggest.
Cheers!

From what ive read thats exactly how youll reduce your batterys life span
Sent from my LG-D802 using xda app-developers app
The more cycles, the shorter the life span. The thing that will destroy the most is heat. These are good batteries, trickle won't do much, heat is the worst. Don't worry so much about it. Nothing you do is going to have much of a noticeable impact.
Thanks a lot for the info guys!

Btw, these batteries are indeed replaceable. Just not in a normal way, and more difficult than say a MAXX. The back cover does come off. Just a thin plastic back that can be removed going clockwise from SIM tray.

Clockwise while facing the screen or facing the back?

Screen to you. Easier to place back starting at bottom and working up to top a side at a time. Just my personal experience.
Any available online stores that provide such replacement batteries?
Also is there a video tutorial on how to open the back cover.
Just in case...

I've done a little research on batteries from such places as Battery University, and learned a few things that might be interesting. I haven't posted enough to post links, but the location after batteryuniversity dot com is "learn/article/charging_lithium_ion_batteries" if anyone wants more information.
It seems that Li-Ion and Li-Polymer batteries are treated essentially the same; the difference is mainly in the packaging. As for charging, they do better if not charged 100%, and never discharged 100%. But one thing they say, which I was told by the salesman when I bought it (but didn't believe him at the time) is that they should not be charged while power is on. The charger is designed to trickle charge the battery, coming on at a certain voltage. But when under power, this cycle happens too often and stresses the battery too much. I suppose it might be OK to charge it while on if you watch it, and remove the cable when it gets to full charge or just under that. I suppose a timer would be ideal.
I just wish I knew how much difference it actually makes, since turning it off means you can't receive calls. I've had devices with Lithium batteries in the past that were left on a charger all night, and the batteries seemed to last for several years, which is probably longer than my phone really needs to last.
I still think its funny that people don't think that there isn't any charging logic in the phone and that it just willfully commits battery suicide if the user doesn't micromanage charging.
Back in the day, early battery tech such as NiCad was extremely sensitive to temperature and the chargers weren't designed with intelligence so they destroyed batteries with 'Fast' charging by overheating. Also, if you never let the battery discharge completely, the battery would start to form cadmium crystals and lower the apparent capacity of the battery. So, slow and deep cycles were the proper way to go. NiMH batteries were far superior and intelligent chargers were introduced but could still suffer the same symptoms of over heating with cheap chargers.
The idea that you can only trickle charge Lithium Ion/Polymer batteries is laughable. The rate of charge is controlled based on the temperature of the battery, if it heats up, the charging circuit clamps the current down, if it is cold it ramps it up. Also, contrary to wisdom applied to NiCad, deep discharges and full charges are harder on Lithium batteries than the earlier tech. In the mid ranges of charge the charger will go all out, when it reaches the top end it slows down to a trickle because the battery is more sensitive to stress at those charge levels. Conversely, if the battery is fully discharged, the charging circuit will start out with a trickle and speed up as the level increases.
On the G2, if there is high resistance across the data pins it stays in slow charge mode, most likely to protect USB ports not meant for charging, if there is low/no resistance it goes into fast charge mode, it thinks it must be connected a dedicated charger. If the charger or the cable gives the wrong setting to the phone the user is left scratching their head.
Luckily the AT&T car charger I bought with my Galaxy SIII works properly with my G2. Sadly the correct cable with my laptop, even with Lenovo's dedicated charging port, it stays in slow charge mode because it senses a data connection.
Edit: Also, the comment about not charging while the phone is on is another hold over from the NiCad days. Lithium technology could care less as all phones have regulated charging circuits now.

Phone getting super hot!... and attempt to burn it down.

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 !!!

The thing is that my battery serial is YS1D420JS/2-B
And how can defective battery make phone become hotter?

phone heating and smells like plastic burn

i was on latest RR rom cm. after charging my phone for 30min it was too hot and even i opened back case and battery removed then i inhaled it was some plastic burn like smell. though its working without an issue. im bit nervous why it happened and is this smell normal.
Not sure if the CM ROMs have fast charging?
If fast charging is enabled it will charge the battery much faster, but also cause it to heat up more. The smell is a side effect of heating up plastic.
I'm sure Samsung tested that it's all safe.
But it was bothering me also that it got that hot so I just disabled the Fast charging (Settings->Power Saving).
It takes a bit more time to charge - I'm usually not in a hurry to charge it, it will still charge in 3-4 hours max. But it will not get that hot and it might also be easier on the battery so it lasts longer before needing to be replaced.

replacing battery

Had anybody had their 6p battery replaced? Can anyone recommend a good battery? What else should I expect as far as costs and turnaround time?
I would especially be interested in hearing if anyone had a bad experience (e.g., damaged device) getting their battery replaced or if anyone has any shops they can recommend in the bay area. Thanks!

I'm wondering if someone tries to fix it for me and they damage it, would they pay for a replacement part? I doubt it and that worries me because I'm sure I can ask a repair shop to do it and they might say yes but they may not be experienced in replacing 6p batteries.

I just replaced my battery earlier today. The camera glass was actually pretty easy, once I used a heat gun on it. The only thing I damaged greatly was the bottom plastic cover. Slipping a thin blade under it left a bulge in it. I had a spare and replaced it.
I did mine today also. It wasn't to bad.. The most important thing is HEAT or the glass will crack. It took me about 40 minutes to finish it

Will you guys report if you see a big difference after changing? I'm ordering a sino today. If you have Accubattery installed I'd be curious in knowing what it reads the replacement battery health as.

I got the Cameron sino battery from Amazon. Accubattery said my og battery was at 78% and my nexus was losing its charge much faster when I purchased it a year ago. My new battery is showing 99% after 24 hours with accubattery. I'm glad I took the risk of swapping the battery myself

I've been running Accubattery for quite a while. Before the replacement, I was down to 60% battery health and getting around 2 hours of screen-on time. I was getting shutdowns at 15% and 20% battery life. Also, a heavy-load action like taking pictures wasn't safe when at less than about 60% battery remaining, since I'd get just a few pictures and then a sudden shutdown.
My battery replacement was advertised to be and looks like a legitimate OEM Huawei part. I'm now showing 107% battery health after a couple charges and a predicted screen-on time of about 4.5 hours. I also used the phone a lot yesterday for video, audio streaming, gaming playing, etc., and it held up solidly compared to what my old battery was giving me.
And I concur with bigmatt503 that heat is the key to avoiding damage to phone parts. I think if I'd have used more heat on the bottom plastic strip before wedging the knife under it, I would have avoided damaging it and would have been able to reuse it, rather than replacing it with a new one. The heat source for me was a heat gun bought from Amazon.

I did a bit more research and found out that the battery I used as a replacement is not a real OEM battery. The ribbon cable on it is thinner than the OEM and the temperature sensor is locked at 25C. See this thread for a lot more information on finding an OEM battery and the non-OEM batteries that do have a working temperature sensor:

I bought mine from an eBay vendor, but I don't think they are still selling the battery.
After reading through the thread I posted about above, it seems like these are the best bets for getting batteries that have the temperature sensor:

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
