Phone not charging while using GPS due to overheating

This is a continuation of the discussion that was started here. Since I do not want to crowd that thread with an offtopic subject, I am continuing here. I am quoting the relevant posts from that thread also.

One issue bothers me a lot. I cannot use the phone for navigation for more than 2 hours even with car charger connected. In about 2 hours, it drains out fully. My latest theory is that after about 30 mins of charging, the battery starts heating up, and so it stops charging.

User error or bad unit I have zero issues with my GPS or car charging. Also what amperage is your car charger capable of outputting.

I am not 100% sure in terms of the amperage. But I tried with a car charger capable of charging a laptop, using the wall charger and cable which came with the phone. I was sitting in the passenger seat, phone was in my lap (not mounted in windshield) and Google Maps was running in navigation mode. For the first 15 minutes or so, I saw that the phone was charging. The charge level increased by 1% or 2%. After I think 20 minutes, it stopped charging. CPU-Z app was showing battery status as
health: over heated or heated (don't remember clearly the text)
power source: connected
status: not charging or discharing
Phone's back was very hot. I unplugged the USB cable and connected it back, and it started charging again! I waited for it to cool down, removed the phone case, repeated this and got the same result.
This is why I believe the phone is doing something to protect it from over heating. I am not sure though.

Amperage is important son too little it will discharge, I think it will limit if too much. Nav can cause some heat for some of these guys but I've never heard of it getting that high my guess is something was wrong.

I have gotten my last few chargers at Sam's Club, they are about $10, and are rated at [email protected]
In an older phone I had a similar issue where my phone would overheat and not charge properly, once I got a new charger I cut the end off the old one and read the voltage with a meter, it was putting out almost 7.1v (should be 4.75-5.25vDC for USB 1.0-2.0 standard, and 5.25-5.75vDC for USB 3.0), pretty sure that is what caused it... cheap components equals cheap quality and flaws. Current rating should be irrelevant, as long as it meets the devices minimum requirements (most modern phones are [email protected]), even if a charger is rated at 2, 3, or even 5 amps, the device should not draw more than it can handle. Current is drawn, not pushed, a device will draw the needed current at the expected voltage, you can't really "over-current" a device by using a power source that is rated at the proper voltage but a higher current. Similar instance can occur by using a charger that has too low of a current rating, the device will try to draw more current than the adapter is rated at and the adapter will eventually fail or fall out of specifications.
Some other good chargers are by Anker, PowerGen, or RAVPower, and of course a Samsung branded adapter will work well, most all of these can be purchased for $8-$15 on Amazon. If the adapter is not rated with a current rating, then skip it, it is probably only 600ma-750ma and will be more headache than it's worth in the long run.

The Skyrocket (and several other Samsung phones) need special "type 2" chargers. Apple charges are type 6, so if it says compatible with Apple, don't use it as it may not work. If the two center pins on the USB port doesn't have a 50 ohm resistor across them (or not shorted) , the Skyrocket will only draw 350 mA. Samsung and older Curve BlackBerry chargers have the resistor. At 350 mA, the phone draws more than the charger is providing, and the charger circuitry heats up trying to keep up with demand.
Jrockttu has a great thread under General called "Fix your Skyrockets battery life"
I've MOD'd all of my chargers, now my phone is happy with the screen on all day while driving and it stays charged, or charges slowly...

To eliminate the possibilities mentioned above, I bought the following:
1. Car Charger: PowerGen Black 3.6Amps / 18W Dual USB Car charger
2. USB Cable: Mediabridge USB Charging Cable
I also installed this app (Skyrocket Charger Info).
Summary of what happened:
With new car charger: Fast Charge (A/C) - Charging at 898 ma
With old car charger: Charger Wakelock - Charging at 497 ma
When connected to mains using factory charger: Fast Charge (A/C) - Charging at 898 ma
When connected to PC USB port: Slow Charge (USB) - Charging at 497 ma
Even with this new charger, phone stops charging once it heats up.
The full story:
Once I plugged in the phone to the new car charger using the new USB cable, the app showed the charging current as "Fast Charge - Charging at 898 ma". This is the same mA value it shows when I plugin into the mains with the phone's factory charger. I drove around with maps for around 15 minutes. Once I stopped, I saw that charge level had dropped by around 9%. I immediately launched CPU-Z app. It was showing battery overheated & not charging (see attachment 1). The phone was hot.
I removed the charger. After I think 1 minute, the battery status became 'good'. I plugged in the charger again. It started charging. While I was looking at the CPU-Z screen, battery status changed from 'good' to 'overheated' and 'charging' to 'not charging'.
Attachments:
(Please note that these screenshots are from another test where I had driven for around 30 minutes, and is not based on the above story.)
1. Phone state once I stopped the car. Charger is connected, but phone is not charging. Note that ignition is on.
2. After removing the charger.
3. After connecting the charger again. Within a few seconds of taking this screenshot, it changed to what is shown in attachment 1.
So I guess I can't do much about this, right?

I can't remember if you replaced the battery or not.... That could also be any issue if it's getting old and can't absorb the charge as fast as it used to... It will heat up quicker.

How old is your battery? And how many times a day do you plug it in?

My phone and battery are now 18 months old. When I am in office, I charge it twice. It doesn't drain much, but I keep it fully charged just before leaving office.

Phone can overheat when under direct sunlight with GPS, screen and CPU working (the most power-consuming activity on the phone happens to be navigation), and also charging. Nothing unusual in that - its internal temperature in this case can reach beyond 100 degrees C. The battery can't charge when above 60-70 degrees C, because it can get physically damaged or even explode.
Concealing the phone from direct sunlight might work.
Limiting the CPU frequency might work.
A new battery might work.

over 25 hours to charge note 10.1 ?

Hi I just bought a used galaxy note 10.1
it did not come with a usb wall charger
after 7 hours of charging
a search said its my usb charger
I was wounding if it is normal for this to take over 24 hours from 0% battery on a charger like this
that only gives 0.5 A
or am I doing damage to my battery by leaving on charge for longer than 24 hours
its like a incredibly slow trickle charge
right now its almost full it claims but im not sure if it will ever be full at this rate
I thought maybe 24 hours but now its 1 hour past 24
I was trying to (calibrate the battery )
so I let it die to 0%
I turned the device on half way though charging
noticed it had an x though the batter so I freaked out and tryed plugging and unplugging it like 10 times
I was wounding how bad that might be for the memory of my battery to do something like that
because I unplugged it before it got to 100% when i was attempting to calibrate it
Im not sure how sensitive these batteries are
but your input would be much appreciated

You could use an off brand iPad charger with your USB cable to help it charge faster your typical phone charger will only give off 0.5 ma, so look for one for a tablet

I know that but I was wondering if leaving it plugged in will it be bad for my battery at all
to leave it plugged in now approaching 28 hours
the charging logo on the screen appears to have approximately 75% charge so far
I want it to get to 100%
should I unplug it if its not charged in 6-8 more hours
im mainly wondering if it is even possible to fully charge to 100%
on a old ipod usb charger or not

You are not harming your device. The only negative is that it will take longer to charge. The red is normal when not using either the correct type charging block or usb cable, it is not harming your tablet.
I would just do what some of the other posters have suggested, getting a new charger made for a tablet, just because waiting that long for it to charge is not practical.

SGN 10.1 GT-N80XX series need a specifically designed charger for them.
One thing for sure, it need to provide 2.1 A, 5 V & most phone charger only supply around 0.5 - 1 A.
Most 3rd party charger also only supply around 0.5 - 1 A.
The other is the data pin(s) & it quite different with Apple's charger.
I've tried several 3rd party chargers & Apple chargers (iPod,iPhone & iPad) & most of it unable to charge my N8000.
You need to buy an original charger for your device.
Or you can try buying 3rd Party N80XX charger on eBay from a reputable seller.
That being said, you also need an original cable to be used with the original charger.
Most 3rd party cable can only supply 0.5 A & some 3rd party charger can only be used using specific 3rd party cable.
A long 3rd party cable (10 ft / 3 m) usually can only supply around 1 A.
For example :
I have a Powerbank that uses its own cable to charge at 2.1A rate, but I can't use my own original cable with it
But my original cable is fine & I uses it to charge using my original wall charger.
It takes around 4-5 hours from 4% to 100% (with WiFi ON & all sync on)
0.5 A can't charge your device while in Power ON condition.
To charge at 0.5 A rate you have to turn OFF your device & it will take a long time to get 100%
(N80XX series have a 7000mAh battery so you can calculate how long).
NOTE:
The battery with red cross icon means that the charger/cable isn't designed for N80XX (usually the data pin settings is mismatching the original design), but it will still charge your device at a very low amperage (lower than 0.5A) to prevent damage for using inappropriate charger.

yes I will as soon as I can
thank you
I am still a little worried that It will never make it to 100% with the only one I have available for now
does not really sound like anyone has had the patience to let it go to full with this slow trickle

Amazon has the chargers and cables.

Fast Charging?!?

Hello.
Can someone explain me how on earth does fart charging works on this device?
I've tried the included cable and charger, third party chargers and i don't see any fast charging going on?!? or any indication on screen that it's happening.
I've read somewhere that you need a special cable to use with the included charger (?!?!) is this true? where do you get this cable?
Phone is amazing but the charging part is really is really weird if you ask me.
Thanks.

do you get any message saying fast charging?

it doesnt show any fast charging message, so i wouldnt rely on such a message to make sure its working. just use the included cable and charger and ull be fine it takes about 2.5 hours to charge from 0-100% via fastcharge

Yeah ...That's why I asked. I plugged a meter to the charger and never saw it go more than 5v 2a.
I think it needs a special cable for the 9v but I can't find any info.
2.5h is not fast charge. My old s6 edge plus used to take around 70-80 m from 5-100% if if you put the remaining 1000mah shouldn't take that long lol

Mean in 30 min 40% recharge . My phone 0 -100% charged in 2:00

trust me, it is fast charge
calculate for yourself: original huawei charger is rated at 9V 2A, thats 18W total. 2A is 2000 mA. mate 8 battery is 4000 mAh.
best case scenario: 4000 mAh / 2000 mA = 2h
now add to that the extra time it needs to charge from 85-100%, because at 85% it automatically slows down charging to prolong the health of the battery and youre at the 2.5h FAST CHARGING time
also, i dont believe for a SECOND that the S6 edge+ charged that fast in your case. check this review: http://www.trustedreviews.com/samsung-galaxy-s6-edge-plus-review-battery-life-and-verdict-page-6
"Fast charging comes as standard with the S6 Edge+ and it works. It charged from 0 to 100% in just 1 hour 45 minutes. Samsung claims wireless charging has also been improved – it’s 27% faster on the Edge+ compared to the normal S6 and S6 Edge."
so thats 105 minutes for 3000 mAh. add to that 33.3% to get to 4000 mAh and u get a total charging time of..... 140 minutes. which is 2 hours and 20 minutes

I will make a full test from 0 to 100. I only charged from 40 to 100 and it took way more than 2 hours... that's why i asked if any special cable was needed. And as i told i mesured the charging rate coming out of the charger and never passed the 5V.
As for non Believing. It's REALLY pisses me off when people write that crap. Why would I lie? what would i gain from it? I sold the phone because i wasn't happy with it.... On the contrary and in case you don't know most sites like the ones you post are PAID to give positive reviews.

I checked with including charger and cable and the app Ampére and it charged with 2800mah. So, in ideaal situation it means a charging time of a proximity 1h and 26min. That means "fast charging". At least in my opinion. ?

that doesnt make sense what ure saying because in this case the site actually stated a HIGHER amount of minutes that it would take the s6 edge plus to fully charge from 0-100% so what now, theyre getting paid to write negative reviews as well?
also, no, ure not "gaining" anything from that, but people tend to exaggerate a lot, do a quick "drive by" in a thread and post random statements based on non-correctly remembered experiences and this is exactly how false statements are converted into "truths / facts". read my post and tell me where exactly i listed anything wrong. check various reviews on the mate 8, they all stare the same thing: about 2.5h for a full charge, give or take 10-20 min. it also compares perfectly with the charging time of the s6 edge+ in terms of mAh/min, and in fact these two phones are indeed VERY close, mate 8 being at 49mAh/min and the s6 series at around 50-52, so just marginally faster... which, again, is also represented by the numbers i listed in my post before
and again: there is NO extra message or notification stating ure in fast charge mode on the mate 8, it just does its job, thats it!
if ure getting slower charging rates / voltages, make sure to use the original charger and original cable and both with a proper high voltage power outlet.

I noticed the fast charging only really kicks in if you leave your phone alone. But if you keep using it while it's charging, it just charges at regular speed. But the moment I put the phone down and screen of for 5 minutes, it quick charges like crazy

I hadn't tested this. After i turn off my phone, a few minutes later it jumps to 9V 2A on my meter. If you turn it back on it goes down to 5V 1A. Must be a phone security thing, which is kinda cool in a way if you ask me.
Btw Apparently quick charge works with non original chargers too. I have a Cheotech 60W 6 port usb with 2 Quick charge ports (which supports 9V 2A/ 12V 1.5A) and it works Using the original cable though.

Don't use fast charging unless you really need it.
Always fast charging overnite (when you're not actually using the phone for many hours) can only shorten your battery longevity more quickly then with normal charging.

When I'm going to recharge for many hours overnite I use a 1A travel charger.

i guess thats the best way to restrict charging amperage although it shouldnt hurt the battery so much, considering that the amperage drops off sharply once level reaches 85% and above...
Sent from my Huawei Mate 8 NXT-AL10 using Tapatalk

Charging a phone with a lower rated current, will cause the charger to "try and match" the current requested.
Amps work in that manner, the device determines the draw. For example, using a 5v 5a (theoretical device) on a 5v 1a device will likely melt your adapter / screw up your phone from improper voltages.
In that case, an adapter may heat up, or if its smart enough (unlikely), it will turn off periodically. Most of the time, it will have an unstable voltage (undervolting) which is how some phones are able to detect an improper charger is used. This is bad for your battery.
I do not recommend charging with a charger that isn't rated for it. This is widely documented.

Wireless charge temperature

Hi all, I buy a fast wireless charge from anker on amazon and I wold this know if my device is working right or is damage. I monitor the temperature and I see that on standard cable (no fast) the temperature stay on 26 °C and with wireless charge (no fast) stay in 34 °C and stay this temperature with 100% charge too. Is normal or when arrive to 100% the temperature must go down?

It should go down and cool completely when charging is over (at least thats how my s7 acts with choetech wireless charger, also using slow charging). Just give it some time after it reaches 100% (10 minutes or so).

Mine keeps being warm after a night on the wireless charger, so i guess charging doesn't stop automatically?
(just have my s7 for two days so that's something i have to look at)
I don't like it being warm as long as it is on the charger.
(samsung charger, that refuses to go to green color when it should finish, it stays blue)

Ok thanks I'm go to change my wireless charge with other model

I have the anker fast charge model (first photo)
And I would to buy the yootech model (second photo)
All see on amazon
edit:
added photo

I have the fast charge Choetech Wireless charger, and the temperature stay high at 100%, between 32 °C et 35 °C.
To solve this , kinda extreme, i bought a WeMo Switch operated by Tasker. One profile that turn off the Wireless charge 15 minutes after the battery come to 100% and another profile that start the charger between 0% and 95%.

First charme with new wireless charge and I can confirm that the temperature stay the same little warm so I think is a normal temperature. This model is better then other is little more big and I can place more easily to start receive energy

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Samsung Galaxy S8 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

I got problems with it...
Sometimes it charges really quick, like Quick Charge does. But then sometimes it says it needs about 8 hours to charge fully.
Thats why i voted Average 3* and charging speeds sometimes even differs if i plug it out and in again.
EDIT:
With the original charger which came in the box it works fine and needs about 1h and 40m to fully charge.

1 hour 45 mins normal charge with original cable and adapter S8 rocking stock AQF7 not rooted

OK, the original charger, what is the Voltage & Amperage Output?
Also.....
From 25% to full charge using a QI Wireless Charger and the Original Charger that came with it, how long to full charge?
From 25% to full charge using the USB out on a laptop (.5Amp), how long to full charge?

Hi are you Iranian?
If you doesn't use official Charger of S8 that it's available in Phone Box it's probably correct that your device will not be charged very fast and you have to use the Official and trusted charger of Galaxy s8 that Samsung electronics have confirmed it.

Been using the s8+ for two weeks
Not sure what to say. When i check with Ampere app, it only shows it charges for 1000 maH
I have Xiaomi mi5 which charges for 2000-3000 maH with the same charger
How could samsung lose to Xiaomi?

After the August security patch the fast wireless charging is broken. I have the European version S8 and a choetech wireless fast charger. Does anyone has this problem after the last OTA update?
Just to point out, the fast wireless charging option is activated in the settings but the wireless fast charging is not working, only normal wireless charging.

I was wondering if it was my wireless charger faulty... did you have any source on this bug or it's just your (and mine) experience?

you cant check charging current with ampere app, because Samsung changed charging method a lot after explosive s7.
basically if screen is on charging current drop to ~ 1000mah. and phone use 9v or 12v only if screen is off.
also if you phone charge longer than 2h something is wrong with your charger\wire or phone can't go to sleep properly due to "cancer" apps who prevent full sleep.
But iam here to ask owners of 25watt chargers, is it worth it? how long it takes to charge it with it?
i not sure if link are allowed here but here it is https://www.samsung.com/us/mobile/m...apter-for-galaxy-tabpro-s-25w-ep-ta300cweguj/

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Samsung Galaxy S8 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
