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.

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.

[Q] Phone warm when charging wirelessly?

I just got myself a Nokia DT-900 Wireless charger (Got it at a clearance at the Nokia store) for use with my Nexus 5 and my Nexus 7.
I charged the nexus 5 with it now. While it charges perfectly, even with a case on, the back of the phone gets a little warm. Not hot, just warm. I was wondering if this is any cause for concern, or if this is normal. Have not tried with my nexus 7 though.
Does the nexus 5/7 work perfectly with the Nokia wireless charger, or is it Incompatibility that is causing the phone to warm up a little?

As it's an LG, I doubt it's any different from the Nexus one. Both have the same specs. Have emailed Google regarding this, their reply was the standard 'We do not recommend using Non-Nexus chargers for Nexus devices'. I told them all QI chargers were actually supposed to work, and am awaiting their reply. Will follow up on this.

I bought a QI wireless charger when I purchased the phone based on excellent reviews on Amazon. I've since stopped using it just because of random overheating and generally the phone was warmer than when charging via USB. It was a feeling that overtime my phone would suffer.

my thoughts exactly

Wireless charging, by its very nature, generates a small amount of heat. It is perfectly normal for your phone to get a bit warm whenever you're charging via any means, but especially when wireless charging. The key is the phrase "a bit warm." It should never be hot to the touch, just warm. The phone was designed to handle this, and there will be no adverse effects. In fact, the heat generated is much less than is generated by the CPU during heavy use (such as during a graphic intensive game).
I regularly use my phone with the official nexus charger (in my car), the Nokia DT-910 (the stand-up version of the DT-900 -- my main overnight charger), and the Samsung S-Charger Pad (at work). All are perfectly compatible with the N5. In fact, the only name-brand charger I'd steer clear of is the Tylt Vu, because there have been numerous incidents of overheating with that charger (i.e., the phone gets very hot to the touch).

Yep, I read online that the Tylt Vu has some issues.
I spoke to Google about the Nokia charger, and they said the temp of the phone is normal. They did warn me that the Nokia does not cut charging automatically when it gets to 100%, and that I should Take it off manually

Using a case increases the distance between the phone and coil which can cause the phone to heat up even more. Even wired charging heats the battery so some extra warmth from the 25% lost energy seems normal.

Lots of people who use wireless chargers say this but I am still skeptical. I would like to see battery capacity tests from two of the same devices. One that was only charged with wireless charging and the other only charged via USB.
My money says the wireless charged device will have significantly less battery capacity than the usb charged device after 1-2 years of use.

Yes, But seeing as most of us use the phone for only 1-2 years, I personally don't see a difference. Maybe the battery will lose capacity over time, but that's going to happen anyway. This will maybe speed up the process by about 20%.

That may be true, but that argument lies on shaky ground, since there are a lot of other ways you can (theoretically) reduce battery life as well. In theory, not allowing the battery to drain completely during each charge cycle, or not removing the phone from the charger the instant it's fully charged can reduce battery life, yet nobody charges their phone that way. There's also the counter-argument that plugging the charging cable in every single day can prematurely wear out, or break, the (very fragile) USB connector on the phone, which would result in the inability to charge at all. (I went through SOOO many Galaxy Nexuses... Nexes? Nexii? Whatever... because of that issue.)
The point is that sometimes, convenience takes priority over the possibility of slightly reduced battery life, and it's hard to argue against the convenience of wireless charging.
Plus, as Srivas95 stated, most of us will move on to the next device long before any such battery degradation becomes an issue.

What you say is right, my Nexus 5 has been with me for just 4 months and I can already see that the jack is kind of loose. That is one of the reasons I got a wireless charger in the first place.

[Q] Oneplus One battery drains very fast when hotspot is turned on

Even when I had the phone plugged into the wall socket with hotspot turned on, the battery only recharged only 3 percent after an hour. My tablet wasn't doing anything as far as I could tell. Auto updates were turned off.
If I remember correctly, when I first got my HTC One M7, it use to do the same thing until HTC released a patch for it.
Is there a way to find out why it's draining so fast? How to stop it?
Thanks in advance.

The 3% per hour charge is only when hotspot is turned on. It charges normally when hotspot is turned off.

No, I am not using the charger that came with it. I am not sure how many amps this charger has but I have used it with my M7 and it charges a lot faster when I had hotspot turned on with it.

Hotspot makes your phone stay active all the time. While this sounds somewhat extreme, it is to be expected that the phone drains a lot of battery when it keeps the data connection open (3G idle won't work well) and keeps processing hotspot informations.
Please post your charger amp rating, I expect it to be below or at 1amp, which would be half of what the phone can be charged with. Also make sure the cable (if not bundled) is capable of handling the current. Many USB cables, especially longer ones, barely manage 0.5amp let alone 1 or even 2 amp.

Everytime i touch my OPO, it drains...

Your M7 has half the battery that your opo has so it would charge quicker.

You need to make sure you're using a 2a charger, otherwise your charging performance is going to be awful whether you're tethering or not. You also need to make sure the cable your using can handle the current properly.

There are two issues Falen , Like everyone mentioned.
+ Charger
+ USB cables.
If you have the official charger ( from OPO which send current at 2 Amps ) and you have a non-official USB cables , it would not be sending the current at the rate that your charger send .
If you are using Official USB cables but the charger is not Official , then charger will not send the enough current to charge the device .
Check the below video to get some highlights : https://www.youtube.com/watch?v=qAozhkQdaow
So when power hunger apps like hotspot , GPS is being used your batter is draining faster than the power supplied and that could be the issue.
So i would recommend to buy the official charger / USB cable and see if that makes the difference , it would be expensive that the cheap charger but its worth the investment.

Battery drain during hotspot is normal on all phone. Basically hotspot took a lot of battery. It happened to all brands, Samsung, htc, and also iPhone.

Nexus 5 not charging properly (?)

While I'm using my phone it keeps discharging. Screen is on minimum brightness, all apps closed, charging with original charger. Stock ROM, same happens with franco and ElementalX kernels. Haven't tried with stock ROM, but that would probably be even worse. Is there an app to check my charger, IE an app that would show charging amperage or something? Thanks
EDIT: The beggining of the post sounds so dumb What I wanted to say is that the phone keeps discharging while charging and using it at the same time. I'll just leave original text like this, it may make some people laugh

well, it depends what you are doing. if its discharging while using and you are only reading a web page, then its not supposed to. but if you are charging and using, and its discharging while you are gaming, thats normal. also it would matter if you are charging it via ac or usb(check how your phone shows the connection). if usb, than it discharging while using is very normal.

right, but does your phone tell you its connected usb or ac? usb has a much lessor charge, and using it while its charging usb can easily drain the battery. oh, and xposed comes with a multitude of undocumented issues. most probably wont affect you, but some possibly can, the modules.

AC. I know about all these things, it's just that my discharge rate while charging seems not to be normal. It is 1.2 A charger, but it isn't behaving like one... Or am I just not used to nexus and that thing is totally normal?

It would be nice if google sold those in my country... Funny thing is that my ~10$ dual usb car charger charges my phone 2x times better than this ”original” one.

The stock charger should be able to keep up with heavy usage, let alone basic web browsing. I can play intensive 3D games and still get a trickle charge. Something is wrong with either your charger or the device. The tricky thing is that all the current meter apps measure current by checking the net current on the battery... which means you're obviously going to have a negative current since your phone is discharging. The only accurate way is to get a USB ammeter. Do you have another charger from an old phone you can try? That would be my first step here.

sounds like the charger might be going bad, they can go bad fairly quickly, and often. try a different charger as said above.

UPDATE:
Original charger is ****. Overnight it charged my phone to 88%. No wakelocks, no sync, just wifi. When I woke up, it discharged to ~70s. Then I said f this ****, plugged my old 0.5 A charger and it charged my phone faster with screen on than the original one on deep sleep. I don't like this.

How to measure charging rate even when the screen is off on S8 plus ?

Hi, I got the S8 plus verizon version.
I suspect I have fast charging issue. The phone doesn't seem to do fast charge all the time even when the screen is off.
I want to know if there is an app that can measure the "overall" charging rate from start to finish when the screen is off. I tried Ampere, it is good app, but it only shows the "current" rate, which very often is around 500mA to 700mA on average on Samsung original charger. Yes, it does occusionally go up to 900mA or 1020 mA. But never over, on samsung original charger. It is normal? I remember I used the Anker charger with QC, it shows it went up to 1680 mA ... However, when I do it now, it does not. It caps on 1020 mA.
Sometime even worst if I a QC car charger, at around 300mA .
When the screen is off, there is no way for me to see the charging rate. If QC is not working, is the phone has some minor defect? I should sent it for repair ?
Please let me know if I have other ways to measure it.
(Thanks in advance.)
Note:. Yes, I also experience some screen shut off or no powering on issue like some members here.

Hi, I got the S8 plus verizon version.
I suspect I have fast charging issue. The phone doesn't seem to do fast charge all the time even when the screen is off.

Although not an app, this works great as it shows the charging voltage as well as the current.

AccuBattery Settings > Notification Priority > Minimum. It will still show in the pull down notification list but the battery % status bar indicator will be removed.
You could probably also disable it entirely via phone settings > notifications.

I wish it did both but this only shows what drawing through the cable into the device obviously nothing plugged in registers 4.95 volts but 0 amps
My note 2 usb was flakey and i noticed it was only drawin .01 .02 amps then in the right spot 1.25

I think you are measuring with usb meter but im measuring with Galaxy Current Charge app & it shows MA per rate current. Can you tell why I'm not getti g stable MA rate, it constantly chaging.
