[Q] Charging voltage / temperature question - Verizon Samsung Galaxy Note II

I bought an Ezo desktop cradle. and am using the stock 5V/2A charger that came with the phone. No problems. Charges fine, and the temp stays around 85-90f while charging.
I also bought an ATT car mini charger that's also 5V/2A, but unlike the Ezo, the car charger heats up to over 100F with no apps running, and the back of the note gets warm. Should I not be using the ATT charger?
Thanks
Alan

Odds are the increased heat is due to driving around and the phone bouncing between towers, or getting varying signal strength and searching for better signal. It isn't a huge increase in temperature from what the wall charger gets to, so I wouldn't be to concerned.

Thanks.. I wouldn't want to fry the phone...

[Q] Sat Nav & Charging Problems (Again I know)

Guys, I know this has been discussed before but this problem is subtly different to previous requests so I'm posting again.
So this is an X10 running 2.1
I have a car charger which is a 2.1amp ipad charger. I also have a 1amp standard car charger. I do not have an SE branded car adapter, but both of the above adapters trigger the charging on correctly as far as i am aware.
If I just leave the phone on charge with the screen off it charges up just fine.
If I leave the screen on with no apps running it charges fine (slower than above)
If I run Copilot with APN Data enabled the battery slowly discharges, even though the charge light is on, and the battery indicator indicates charging.
If I run Copilot and disable APN Data the battery just stays at the same level and neither charges nor discharges. It seems to meet a state of equilibrium.
I ran Copilot with APN enabled and SetCPU limiting the CPU to 225MHz and the battery still discharges (albeit at a slower rate than without SetCPU).
I have the phone screen on minimum brightness and I am not running anything else unnecessary. I have checked battery temperature and I have never seen it above 32 degrees.
The same applies for Google navigation instead of copilot. Both discharge the battery whilst on charge.
I also noticed the other day that something went a bit mental on the phone and was consuming high CPU while the phone was on my branded SE AC wall charger and the battery ran down until the phone turned itself off whilst on charge.
So, does anyone else experience the fact that the phone does not draw enough power via the USB port to cover the current draw on the battery. I have 2.1 amps available on the car adapter and its clearly not drawing anywhere near that. Running it on the 1 amp charger also makes no difference. The SE branded AC adapter is rated at 750mA.
Is this normal?
Any clues?
At the moment to complete a 6 hour journey in the car using satnav on my X10 I have to take 2 or 3 fully charged batteries with me, in addition to having it on the charger.

[Q] Car Charger Overheating battery, stops Charging

Hello,
I have the three EVO 4G phones and one EVO 3D phone. Along with a few different car chargers including ones from HTC,Rocketfish, PointMoblm, 12v USB radio plugin,12 volt to 110volt with USB plugin and wall charger plug.
The problem I am having is when I travel distances over 100 miles using GPS "Google Maps" and/or Pandora streaming. The Battery get so hot it stops charging or will randomly reboot phone and the battery is dead or close to being dead when I get to my destination.
Is there a way that I can run the phone without the battery or software mod that will stop battery charging in different time intervals while in car mode.
Any tips or modifications on 12v chargers I can try?
Maybe you could try under clocking the cpu during these trips.
Reducing the CPU will reduce the heat it produces as well as the drain on the battery. Both will help with your heat problem.
I have the same problem with my E3D and the underclocking didn't work. My phone is underclocked when the screen is off, but when I picked it up it was like hot coal.
I paid a total of about £2.50 (£1 for car USB connection + £1.50 USB cable) for the charger, so was wondering if it's the quality of the items.
I plug mine into the cigarette lighter too, so don't know if this is part of the issue.
I will try to lower Cpu during AC charging first since my primary charger charges at AC.
How low should I start? I have SetCpu to max 486 and 192 min with screen off.

[Q] Charging speed / wireless chargers?

Hello everybody!
I've got two questions:
Since I'll be receiving my direly awaited S6 Edge 64gb tomorrow, I have two questions which I couldn't really get any good answers for.
The first one is about the speed of charging. Since the battery in the S6E can't be switched so easy, I'm a bit concerned about battery health, especially since I plan on using the phone for a long time (budget is tight). Now with my last phone (which unfortunately I had to sell in order to come up with the money for the S6E) I used one of my computers USB ports to charge the phone over night. I read somewhere, that it's better for the battery to be charged slowly and since my computer powers the front USB even when switched off, I always used it to slowly charge the phone overnight. It would be faster charging with a wall outlet, but I didnt need it to, so I figured it would be beneficial for the health of the battery.
Is that actually true? Is there maybe even some way to keep the phone from charging higher than 80%?
My second question is about wireless charging. I'd really like to get a wireless charger for my desk at work, however I will be using this ->
*cant post the link, it's the "Galaxy S6 Edge Case, Spigen [CURVED BUMPER] Neo Hybrid Series Case for Samsung Galaxy S6 Edge - Satin Silver (SGP11420)" case
case on the phone. Are there any wireless chargers, that will go "through" that case?
If so, do these chargers charge so fast, that they let the battery health deteriorate? Do they stop charging when the battery is full or is there danger for overcharging or heat building up because of the case?
Thank you guys very much in advance for answers, I'm just really looking forward to the phone and I'm eager to do everything right ^^:fingers-crossed:
You shouldn't worry really. There are rampant unjustified myths about quick-charging. If your device is designed for that feature, the processor and software work in conjunction to prevent damage to the battery. The turbo charger provides large amperage to charge quickly, then reduces at an appropriate level. I've used turbo or quick charging since the Motorola Droid Maxx 4 years ago. Today, those Maxx still function as well as the first day. I do not purchase any device that does not have turbo charging. As far as wireless charging, a decent charging plate should have no issue. I use only TYLT and I build furniture around these things. I put glass top over them and never have problems charging.
Thanks so much
Do all the wireless chargers feature "Turbo charging", or do you mean charging with a wall outlet by that?
I've read in some reviews, that in combination with the S6, the tylt charger tends to fully charge the phone, then stop charging, then after a while commences charging again, leading to the phone screen lighting up and the "phone is charging" notification sound playing, then turning off again when the battery is fully charged and so on.
Did you experience any of this?
@myh0mie I guess we are in the same state, I'm also receiving my S6 Edge on tuesday and have been having the same questions as you have about charging this thread will come in handy
@quangtran1 If you use the fast charger on your S6 Edge, are you also experiencing the screen rotation issues people are suggesting that are caused by the fast charger? I really wanna know how i should be charging my phone to avoid damage once i receive it. Thanks in advance
I myself do not have the screen rotation issue with fast charging. I do know, however, that Samsung has acknowledged this on "a very small number of S6 devices, and has the solution to resolve it". Samsung did not disclose whether this was a hardware or software issue. @myh0mie Wireless charging does not offer fast charging. Fast charging comes from the 2-amp wall block.

Oh cool then it's good to hear that it seems like it's NOT the fast charger that causing the issue and the fact that Samsung already has a solution to it
I haven't had a screen rotation issue either, on a 64GB Edge (AT&T).
As far as methods of charging, seems like the "Adaptive Fast Charging" is definitely the fastest way to charge the phone. The feature only seems to work with the packaged charger, though. I have a few 5V 2Amp chargers that don't charge my phone as fast as the packaged Samsung charger. It's extremely effective when you're very low on battery life, below 25%.
If you look at the Samsung charger label, it says it outputs at 9V 1.67Amp OR 5V 2Amp. The 5V 2A is standard on many chargers. The 9V 1.67A must be the Adaptive Fast Charging.
For wireless charging, I purchased a few PowerBot Qi chargers (very good price and reviews on Amazon) and supplied them with 5V 2A power to keep myself topped off at work and overnight. To me, they seem to charge the phone at about the same speed as a generic 5V 1A power source.
My last phone was a HTC One M7 and I kept a close eye on the temperature with an app called Cool Tool. I still run the M7 in the same operating environment as my S6 and have noticed that the S6 runs 10-15 degrees (Fahrenheit) cooler than the M7 in both charging and non-charging states. Hope that helps.
I have the S6 edge with the TYLT desk charger and the TYLT car charger dock. Neither of them charge the phone quickly at all. I am not a fan of either really, but I use the desk charger on my desk at work and it is fine to keep the phone topped up throughout the work day (I forget it's even there). The car one, however, is going back. It charges hellishly slow, especially if you run any tasks like music streaming or GPS. Not a fan.

HELP! Note 3 Neo gets too hot, stops responding!

The phone is 1.5 years old, everything was going smoothly till 3 months ago,when I decided to buy QI wireless charging pad and receiver. The charging pad is rated at 1.5A and the receiver coil is rated at 1A. For some reasons, the charging pins near the battery (where you are supposed to attach the qi receiver pins) don't respond to any charging voltage, whether from the qi receiver or normal wall charger.
So I extended a very thin wire from the receiver chip and connected a DIY micro usb pin to it's end. Now the receiver sends charge to the regular charging port, I know I could just buy similar "forward universal qi receiver" for this purpose, but that's the same apart from looks.
Anyways, last month the receiver coil got detached from the micro usb pin, so I stopped using wireless charging and started using the regular wall charger (stock samsung, rated 2A) again. I will buy that forward based universal qi receiver later on.
Since then, the wall charger gets quite hot and the metal part of the usb cable (which is inserted in the charger) gets TOO HOT. The phone's motherboard gets TOO HOT, I have removed the battery cover and inspected, the battery isn't the culprit, it gets a little warm as usual. Phone stops responding to touch and buttons. This happens especially when 2G or 3G data is on, but no apps are running in the background and no sync,downloading/uploading is going on. The phone lies in idle state with screen off and mobile data on.
The phone doesn't get this hot when:
1. I charge it via other phone/tablet chargers (belonging to parents), I have tried with 3 chargers, rated 1.5A, 1.2A and 1A. None of these 3 result in overheating EVEN IF I keep the screen on and use games, browser etc!
2. Charge it while switched off.
3. I had a charging cable of a cheap micromax phone lying around, it's not a data cable, simple charging cable. This cable doesn't result in overheating even with with the stock charger.
4. Once the battery level reaches around 70% (regardless of charger and cable), it doesn't get hot even with mobile data on, screen on and playing games etc.
FYI, The wireless charging setup didn't result in the phone getting this hot ever. As you all already know, the charging pads and receiver coil get quite hot but they also cool down quickly. Also the intensity of heat produced by receiver coil is not too high so as to heat up the whole phone. NOTE that I was using the charging pad with the stock samsung wall charger for that 1 month (maybe that ruined the stock charger somehow?).
Obviously if I start using the wireless charging setup again, this problem won't crop up. But I need to know whether there's any hardware damage/problem or not. To avoid this problem, I could buy another charger of lower amperage, like the moto e charger.
INFO: The phone is SM-N750 3G (Indian version) with no hardware changes. It's running on a custom rom "Unikat V5", alongside the custom recovery "Philz touch". I had installed this custom rom around 10 months back. Overheating problem started ONLY after trying out that wireless charging setup and removing it.

Question How Warm Does Your Battery Get While Charging?

After getting a new charger that charges at 22.5W I've found my phone gets noticeably warmer than it did with the weaker charger from my old LG G8X. According to CPU-Z the battery gets up to 39.2*C and the phone is noticeably warm in my hand with a Google case on it.
So if folks wouldn't mind checking their battery temps after having been charging for a while and then sharing here I would appreciate it.

Try to keep it between 82-100F when charging.
Put a fan or damp microfiber cloth on it if need be. At 102F or above fast charging may disengage.
Stop charging if it gets in this range.
Don't start charging below 72F, 82F or higher is ideal. It's an electrochemical reaction that needs heat to work properly.
Low temperature charging can cause Li plating which will permanently degrade the cell.
Never attempt to charge if at 40F or less.
