HELP! Note 3 Neo gets too hot, stops responding! - Android Q&A, Help & Troubleshooting

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.

Car charging problem with Touch HD

I purchased a new vent holder with a car charger, and it charges the phone up OK when it is off, but if it is on it says charging but does not actually charge. This is especially annoying with Satnav and after an hour or two the phone dies and I don't know where I am going!
Anyone know what causes this? I guess it can't provide enough power for the device, especially when using the internal GPS, but I think it doesn't even keep up with the device is just turned on.
I am getting another charger just in case, but never had the problem on my old Touch....
..
try -> start/settings/system tab/power/battery tab - uncheck the box "when the device is turned on...."
It isn't ticked...
..
try ticking it..
That will have the opposite effect, it charges fine when plugged into the wall, the problem is something to do with the car.
Does anyone use satnav on a touch HD and have it charge at the same time?
Well there could be one or two issues.
On the USB port there are four connections, a positive and a negative and two data pins. When you plug your Touch HD into a PC power is supplied down the power pins and after negotiating with the USB controller chip over the two data pins the phone will pull up-to 500mA from the power supply to run and charge the phone. This is so the USB port on the PC is not damaged by the phone overloading the power supply to the port.
Without the negotiation with the USB controller chip the device will only charge at 100mA.
But 500mA is not enough to charge the phone with everything running, you will need at least 1000mA to do that (1 Ampere). So that is what your wall charger pushes out. But how does the phone know it can charge at a higher rate? Well inside the charger the data pins on the USB connector are wired in a way that the phone 'sees' that a higher current is available, and pulls a higher charging current.
So what you need is a minimum current 1 Amp car charger. If you already have a 1 Amp then the chances are that is does not have the data pins connected properly and the phone will not draw the higher current, meaning it will only charge at 100mA.
Thanks, I am going to try another one and see if that helps, perhaps it is just faulty, otherwise I will check if it is 1Amp.
Cheers.
I contacted the seller and they sent me a new one, which works. So it turns it my charger was just faulty.
What's the rating of the new one? and where did you get it from. I bought a 2amp (supposedly) but it doesn't give me more than 500mA.
I've had this problem and it sucks! As I'm always out on the road. But I have found a few solutions. I purchased a mini usb charger from asda for £6. After adjusting the backlight to medium this charger seems to keep the power level the same as it was before you plugged it in, so It doesn't let the battery go flat. I've now learnt to keep a spare charged battery in the car just in case it fails.

USB car charger

Hey guys,
I was wondering if these USB car chargers are compatible for the TP2?

I'm asking because I remember in the past I used a HTC charger to charge the O2 XDA Flame and it charged. However, the phone started acting VERY weird and freeze a lot. I ended up having to hard reset it
Thanks!
I think any USB charger for electronic gaget that has a output of 5.0 v should work. It does not matter if it is an AC charger or and car lighter charger. I got one of these AC and another car lighter charger. There are all 5.0 v output. I use them to charge Ipod and phones.

Thank you
It's best to choose one that can supply enough current (I think the wall charger supplies 2A, but 1A should be ok). Some devices will still trickle charge with a lower current, but others just won't trigger the charging circuits at all.
I had a cheap car charger that seemed to work ok most of the time, but it got worryingly hot after a while.
My TP2 came with an official HTC charger, so I use that now and it's great.
I have noticed that if the phone is OFF then 1A is not enough and usually stops charging but if the phone is ON it completes the charge..but takes for ever.
Has anyone experienced the charging overheat situation where the led flashes orange and green? I dont know if that is the situation but it only happens when I am charging in the car and the unit gets hot.
My old "OEM HTC" charger I got on ebay (the one with the blue HTC light) just stopped charging my phone after about 10-15 uses.
It lights on (charger), but my phone doesn't catch any charge lol
I got a 1A one, and unfortunately it cannot produce enough juice when running the GPS (copilot), after a while the phone shows a message telling the charge current is not enough.
The wall charger that came with the original box is 1A too, thus the problem might be with the cheap car charger.
Brando sells a 2A car adapter that should do the trick. They're out of stock right now, but it may be worth a look.
Hey!
Mine is a cheapo but does the trick. Charges the phone with satnav running, today went from 23% to full in less than 3 hours. Plus it's really tiny so I can keep my ashtray closed all the time. Using it with mini retractable cable, it all fits in the ashtray and it's handy to use.

The manual states that the output of the AC charger is 5.0 volts and 1 amp. That means the output of the DC/car charger should be the same. Using a 2 amp current might be charging the device faster but it would probably generate more heat and might shorten the battery life.
one tip, regardless of which charger you end up with, is to not leave the phone plugged in while starting the car. my understanding is that there can be be large voltage surges or fluctuations during the startup. depending on the design on the voltage converter inside the charger, some of that may be making it through to the phone.
i once had a AA NiCd battery smart charger that went wonky after using it in the car a lot, but that was with a straight-through 12V car to charger connector.
I made my own charger for using as a GPS on my motorcycles.
There is a charge select line in the plug. If the phone detects that it is connected to a USB port, the phone will not 'pull' more the 500ma. If that line is set to indicate a non USB port, then the phone will pull 1 amp. MAX (I never saw more then 900ma myself).
If you have the wrong charge plug, it may only charge at 500ma. If you have the correct plug and the charger can manage 5 amps, the phone will still only take 1 amp max.
For a while I used the phone in a waterproof box called an Aquabox. It would overheat during charging. I now only charge the phone when it is not in an enclosed hot space.
I'm still using the off-brand 'for Blackberry' car charger I got back when I had my Kaiser. Seems to be working just fine with this phone as well.

[Q] loses 450mAh while using GPS

Has anyone noticed that phone does not charge while using GPS. The charging indicator is on but when I look at the stats it says discharging at -450 mAh. Is this the way it is and if so, is there a fix? 1 hr 42 m with 73% display on battery use and 43% charge remaining, but was plugged in the entire time while driving under an hour home. I am using the same Motorola high performance charger that every other phone is charged fully even when using GPS.
are you absolutely sure the charger is giving the full 1A?
What sensor app are you using to see the battery discharging?
Mine charges normally with gps on.
Sent from my HTC
LTE 4G Rezound
I was curious so I tested this with "Battery Monitor" I have it plugged into my laptop currently which only gives +500mA. and not the +1A that you get from a wall/car/high power usb port.
the app is showing +257mA with GPS on and functioning normally.
So charging good here... Might be something with your motorola charger? It could have a sensor in it to detect 'trickle charging mode' that is improperly engaging when connected to the HTC causing the charger to put out a minimal 'sustain only' level of amperage.
good luck!
you need a charger putting out 1A ... most car chargers put out 500mA so find a good one off monoprice
Here's what I'm doing. I have a Belkin 2.1A(2100mAh) USB car charger dongle. The problem is, once i connect the USB cable to it the phone registers it as "Charging USB" and does notcharge anywhere near as fast(power-wise) as if the phone was registering it "Charging AC". I'm not keen on using a power inverter to get the full AC charge so instead i am going to go pick up a cheap micro USB cable, splice it open, then disconnect the data wires(green & white ones) & then tape it back up. By disconnecting the data wires, the phone will no longer think it's a USB connection and then charge via AC, getting the best charge possible.
that should work ^ if thats the problem
I've found that using the included USB cable with a Belkin dual port USB car charger allows the phone to charge as if it were plugged in to a wall. I'm guessing the included cable has a different layout than standard Micro USB cables.

I'm guessing that I have the same belkin dual port (2.1amp and 1amp ports) and the best I've seen out of it is about 250mah charging. This is using the supplied usb/micro hdmi whatever cord for the phone.
I have seen discharge rates off the charger of 750mah which is the highest I've seen on any phone. I'm guessing if you are using the nav on your phone with the screen on, it will probably still be using battery while plugged in.

Possible, but says AC charging in Battery Monitor widget. I will post a few pics.
Here are a few Pics. you can see a couple of things.
-Charger rated at 950 MA out. and no other phone I have owned lost a charge while driving including TBolt, Charge, Bionic.
-Shows as AC charging
- Spikes of good charging detected
Put on Normal power mode today on the way in. live wallpapers did not wrok, just flickered. 3G on vice 4G. Battery still went down, but above 90% on 40 minute drive in. Screen low but on. Bluetooth speaker.
Maybe it is the iBolt car mount. See review online. will try without dock this afternoon on my way home.

Pros: Options for different backs
Cons: Does not charge the phone while it is in use
Try playing pandora when the phone is 100 charged. After 45 minutes on the car mount (and yes it is plugged into a charger and all indicatros show it is charging) and the charge level is 84. Using the same charger but plugged into the phone, playing Pandora for 45 min starting charge level 68. Ending charge level is 100.
Yeah, something is telling that charger to not give you full juice
Rezound
ok, drove home off the window mount and just on charger, all same except full brightness on screen.40 minute drive. came up 7% battery vice down from 100 to 43%. nedd a few trials to confirm, but looks like window mount is throttleing juice.

i have seen spurts up to 913 with GPS off and screen just turned on. Using battery monitor widget. Not on window mount, just charger.
I can confirm. The car dock will not charge your phone atleast not with the screen on and nothing else running but battery monitor widget.
I bought one and tested it extensively yesterday. I used a Verizon 1a charger and a generic 1a charger. With the dock and both chargerz the phone DIScharged(as in LOST battery power) at between 100ma and 200ma. Without the dock using the same chargers and changing nothing on the phone the phone charged at between 50a and 300ma.
I did the test several times to eliminate any random things the phone may have been doing in the background.
After doing that controlled test I played with it some more and no matter what I did I could not get a positive charge with the dock attached even in airplane mode with the screen backlight at minimum. Without the dock using the same chargers i ran Pandora and a police scanner both outputting through the phone speaker, gps, wifi, mobile all on, and screen on auto and still had a very small positive charge.
Moral of the story DO NOT BUY THIS DOCK unless you dont mind it just being a piece of plastic that holds your phone in place.
I wonder if there's a quick mod to it to get it working right. Like the soldering of the USB chargers I've seen.
Rezound
I just went ahead and bought an extra battery so I wouldn't have to charge in the car. Only takes 20 seconds to pop in a new battery.
Can charge both batts while I sleep at night.

I was looking for a high current charger for my Android tablet and there was a review that talked about compatibility. Some of the high cap chargers appear to be designed for Apple products and the pin wiring is subtly different. So, on some non-Apple products, the charge is only recognized as a lower power, 500mah charger and the users reported that some devices would normally charge and others would not. Some of the dual port charges also split the power. The 2.1 amp port and the 1 amp port cannot be used at the same time, depending on what is plugged into them. This was also brand specific. I ordered the Amazon Basics 2.1 amp dual charger and will see how that works. I have noticed a difference in charge rates between my Motorola charger left over from the Blackberry and the Verizon OEM one. The VZW one is faster.
I do the same thing I have been doing since my Windows phone days.
I use the AC cord plugged into a 12v to AC adaptor(screen set to 100% bright and no timeout).
I drove 6 hours last week ruuning Google Maps/GPS & my battery was 100% charged when I got to my destination.

Slow charging notification

Seems ever since I updated to the latest OTA update, if I plug my phone in on certain chargers I get a notification stating slow charging enabled please connect to your factory charger. Anyone else having this issue?
It seems to do it on any charger or 12volt car to USB adapter capable of outputting 2 to 2.1 amps

Same here. Glad to hear it is not just me. I just got off with NA HTC Tech Support. There official stance is that they do not recommend or support using any device other than the official charging cable and plug in device. They went as far to say that they do not support charging in the car. I just about flipped my lid on the phone.
Here is the link to their site: http://www.htc.com/us/support/howto...783&p_name=droid-dna-by-htc-(verizon-wireless)
"Only the power adapter and USB cable provided in the box must be used to charge the battery"
I was told by Verizon that this was just a scare tactic, while HTC says I am not getting the right charge and they have no answer since they do not support DC charging in the car. Any info people have is appreciated. It works fine with Hard Wired DC -MicroUSB, but not with any USB Plug in.
Any apps that would help me measure the amount of charge it is getting?
Thanks in advance.
What are the specs on your car charger?
Sent from my HTC6435LVW using Xparent Red Tapatalk 2
So odd that they would do that, especially with the power draw of the phone. However you can charge using the battery packs?
My car adapter is a Macally USB car adapter model carusb10 output 5v/2.1 amp x1 500mA x2.
As for my house adapters the RCA 2 port USB wall adapter. 2.1 Amp x 1 or 1000mA x 2 I believe.

Everyone with a stock DNA unplug your charger and flip it around. As in flip the prongs. It should give you this message even with the HTC supplied one. Or try this. When you use another charger and it gives you that message unplug it and flip it. It should straighten out. I dunno. Something about the way the power is drawn.

I have tried several different USB adaptors, from Razorfish(BestBuy), Belkin single USB input 2.1amp, innocell (RadioShack) dual SUB 3.1amp. Same problem on all.
On the other hand, any direct Wall connection with USB cable attached seems to work fine.
Also, I have the Motorola p4000 battery backup and when I plug that in, it also works fine and views it as AC.
Swapping the pins didn't work for me, same issue. Its a pita for me especially charging in the car because when using phone for navigation it charges so slow that it can't actually charge my phone and my battery decreases. I've went the route in the car I use my nexus 7 charger connected to an inverter.

From my phone conversation with Seth from HTC Support, the slow charging warning is due to the update because the update incorporates the faster charging feature that qualcomm & htc have referenced too recently (can't remember what its actually called). The phone has a new type of charging setup that makes it charge faster than some other phones.
Unfortunately some chargers (wall/car) dont supply enough voltage to activate the charging feature so while the phone does charge fine (it charges at standard phone charge rate) it cannot charge at the faster rate due to the charger.
He states that this will not harm the phone and ther phone will charge fine and it a normal time. You can disregard the warning. For those that like the faster charge rate, you have to use the right charger/cable.
Before the update our phones were mostly charging at the slower rate and that's why most didn't see a warning unless the cable being used was below the standard rate of charge.
Hope this helps

Well with the faster charging enabled it does charge pretty quick especially using my nexus 7 wall adapter, even with my Nokia Qi pad. But man that last percent takes a while.
As of now I'm using supercharged hatka ROM slim 3.0.3 and getting good battery life. Even in the middle of nowhere where 75% percent of the time when I'm in the plant its searching for signal. I'll leave work after 8 hours and still be at 60%
Guess you can say its the only negative I have for the phone. Trust me the battery life is much better in the plant then my old bionic. I use to have to change the standard battery after 4 or 5 hours as it was completely dead.

Last night I received my daughters replacement Rezound from the warranty company. It came with a 1 amp wall charger.
I plugged it into my DNA and did not get the notice of slower charging and it charged quicker than I've ever seen it.
Too bad my 2.1 best buy one won't.
The quick charge capable chargers must output just slightly higher voltage to trigger the rapid charge mode.
I'll experiment some day and see.
This is a known issue. It all comes down to there being no set standard for USB charging. Android, apple, tablets, they all just seem to do their own thing.
The phone is checking the pins on the charger. If the data pins are shorted, then you get fast charging. If not, then it will default to the slower USB charging.
That last update that came through added that 'Slow Charge' warning. I saw it on my gf's DNA. My DNA is rooted and ROM'd so I don't have that. You can still check for the charging speed on a device by going to the Battery page in the settings. Up on top it with either say AC (which is fast) or USB (which is slow).
The supplied HTC wall chargers have the data pins shorted within them, so any regular USB cable will allow you to charge at the AC rate. You may remember some years ago there used to be Charging Only cables and they were regular USB cables that simply had the data pins shorted.
Most car chargers do not have data pins shorted. I have used a number of different ones from monoprice and none of them will charge at the AC rate.
There are videos on youtube showing how to open them up and solder the data pins. You can look for charging cables on amazon (but that seems lame), or you can find a car charger that just actually works.
There is a cheap Motorola charger on Amazon that will give you the fast AC charge.

I kinda figured it was something with the pins if I wasn't voltage offset.
I did find that one of my car chargers from best buy runs in quick charge. The cable I fixed, rather than using a usb cable in a slot on the charger.
The best number 2.1 amp wall charger uses a data type cable.
Maybe I'll check into shorting the pins on that sucker to get quick charge mode.

The supplied HTC wall chargers have the data pins shorted within them, so any regular USB cable will allow you to charge at the AC rate. You may remember some years ago there used to be Charging Only cables and they were regular USB cables that simply had the data pins shorted.
Most car chargers do not have data pins shorted. I have used a number of different ones from monoprice and none of them will charge at the AC rate.
There are videos on youtube showing how to open them up and solder the data pins. You can look for charging cables on amazon (but that seems lame), or you can find a car charger that just actually works.
There is a cheap Motorola charger on Amazon that will give you the fast AC charge.

The phone is doing more than checking pins now. I have a 2.1 Amp dual charger with pins shorted and get the warning. It happily charged in AC mode before the update. The charger can also charge a nexus 10 at 2 Amps. I'm guessing the kernel devs will have to locate the source of the warning. I thought the resistance between the data pins might be the trigger, but there is no difference between the HTC charger and my dual charger. It does seem my car charger is unaffected.
I have found that to trick the phone into AC mode you have to short the the actual cable. Hence strip the insulation off the wires and short the data wires together. Has worked for me on all my chargers.

This message does not have to do with the update. I have still not updated my DNA and have been struggling with this for about 6 or 8 months. I am on 2.08. The issue has continually gotten worse since the first time I saw it. At first it would just appear about 1 in 10 times I plugged it in to a car charger. It then got to the point where it would only not show the message with a certain car charger. Now it is showing it on the one car charger that works, but if I mess around with it and unplug and replug it a few times it will finally charge normally. The last few days it has started showing the message on the OEM charger. I have cleaned out the port on the phone and cables quite a few times now, but it doesn't help. I found that doing that only helps if it gets really full of lint and the cable rocks in the port causing it to loose connection if you move it, but it does not change the slow charging message at all. The phone is also definitely not charging at full speed when that message is shown. If I have it plugged in and it shows that message my battery actually drains if the screen is on. With the screen off I only gain about 10% per hour. I am not sure where the issue is, but I think it is different in different circumstances. In my case I think it is the phone itself, but from what I have read about others experiences it seems their problem might be the charger/cord. I hope this gets sorted out soon.

It could be the charging equipment your phone or it could also be the power source not providing enough power to the device for it to charge fast so it charges slow.

[Q] Slow discharge with magnetic charging USB port

I've set up my Z2 as a Sat Nav in my car and using a magnetic USB lead plugged into a 3A charger. I've noticed that the phone doesn't really charge with Google maps running and playing music. It slowly loses the charge. Has anyone come across this?
Have the same issue with mine. I've got a magnetic adapter that I use with my ordinary USB cable and it can't charge the battery when I use waze and Spotify. At night I use a magnetic charger cable and then it's charging fast but not with my adapter.

Mine also charges very slowly or even discharges depending on the usage through magnetic port. My guess its due to cable being ****ty
I'm wondering maybe the cable is not delivering enough current despite my charger can output 3A.

i think this might be a Problem of the magnetic Ports!
Pretty sure screen on, gps and active sat navigation type app on nearly all android phones will lead to this.
Fact is the device is using lots of power, so much that the charger can't keep up. You also will likely find the phone will struggle with heat issues while doing this.
