Any of you guys ever use the Google Navigation w/ N1, while plugged in to the car charger and find that it's still discharging even if it has the charging icon? Like the charging rate is less than the discharge rate.
I've used it in the car for hours, must be plugged in for me, otherwise it would be dead very soon. Mine gets hot as hell with the gps on while plugged in and driving looking at the screen.
I bet it's possible to achieve a negative rate of charge with enough stuff going on inside the phone.
I like it better than the tom tom though.
I have experienced this. I got to work and, despite having been on charge all the way there, my battery had depleted. 100% to around 85% on a 40 minute journey.
However my car cigarette lighter socket is extremely temperamental, and so it frequently looses connection. In the case of my N1 I was hoping this was the problem, rather than the phone. I can have the car repaired!
I have had phones in the past when it was possible to achieve a negative rate of charge (Samsung Omnia using internal GPS and HTC Wizard using bluethooth GPS). Particularly fun was the fact that the Wizard won't charge from a car charger when it gets too low. This left me STRANDED in the middle of the US.
Navigate uses alot of juice because of the GPS.
The phone can only charge so fast. If the usage is faster than the charging rate then obviously you'll get a slower charge or a depletion.
It's most likely your car charger. It is probably only pulling a small amount of power. There are some 1000ma car chargers you can buy that should work better.
I also believe the official car dock from Google will keep it charged too.
It definitely depends on the car charger and your settings.
My first car charger supplied 500mA (I had it lying around from some other piece of equipment I had bought). I did an experiment with the screen at 100%, navigating, and streaming Pandora. I lost something like 15% of the charge in 45 minutes or so.
I now have a 1000mA charger (just a couple of bucks at monoprice.com). What that same configuration, the battery goes down very, very slowly. If I don't run the screen at 100%, or if I turn off the screen during long stretches between turns on the highway, the Nexus One gains charge instead of losing it.

go plug your nexus into the car charger and go to settings, about, and see if it shows usb or ac and you will figure out the problem. it prob will say usb which means its only pulling 500 ma rather than the full 1000 ma that it should be. my car charger pulls the full amount and it can actually charge the device during navigation.
I own a Galaxy S2. I have tried it using for navigation many times only to find that the battery discharges fully within 2 hours even if the phone is connected to a car charger. I used to think may be its because my car charger doesn't provide enough current to maintain the charge. But recently I found out the culprit. After around 20 minutes of use, the phone battery starts heating up, and it stops charging. I verified this with CPU-Z. It clearly shows battery overheated, power supply connected and not charging.
I was wondering if S4 also has similar issue. Has anybody used it for more than 2 hours with Google Navigation continuously while connected to car charger?

The most I have used it for is about an hour and half, and while the phone did heat up, it did continue to keep charging while connected to my in-car charger (just a cheap one). I can't remember whether the charger was able to keep up with the discharge though, I think it did. I was driving in bright sunlight, so I had screen brightness on max throughout that time.

I've found that the USB cable can have a big impact on the charging current. I had the same problem with my car charger not keeping the phone charged, even though I was using a 2A charger. When I changed the USB cable I managed to quadruple the charging current (from 300ma to 1200ma) and solved the problem (I measured the charging current using the Galaxy Charging Current Lite app).

In my case, I believe it was not because of the charging current or cable. I was trying with a car charger capable of charging a laptop, using the wall charger and cable which came with the phone. When the mobile stopped charging, I checked in CPU-Z app. The app was clearly showing status as "power supply connected, not charging and battery overheated". If I unplug the USB cable and connect it back, it will start charging again!
To make sure that I didn't miss anything, I will try with the app you suggested.
Just to update: The Galaxy Charging Current Lite doesn't seem to work with my Galaxy S2. It doesn't show any value.
Does anyone else have any experience with Qi wireless charging receivers for the S4? I bought one from eBay at the end of last year (item no
151128038769), and it was fine for the first few months, but now it doesn't seem to charge the phone at all. I get a popup message when the phone is placed on the correct part of the charging mat (although this message doesn't always pop up as reliably as it used to), and the charge indicator displays in the notification bar, but if I return to the phone half an hour later it has actually lost charge.
I've tried this with two different charging pads, from two different manufacturers, and neither charges the phone, even though the phone gives the impression that it is being charged when I first place it on the mat. Charging using a cable still works fine.
I was wondering whether others had experiences of wireless charging?
Update: I just checked the charge status with the Galaxy Charging Current Lite app. When the phone is on the pad the charging current shows as 640mA (which should be enough to charge?), but the phone is actually losing 1% of its charge every few minutes.
???
are you using an adapter cover or a connector for the qi charging?, maybe they're not aligned well
also,i just checked and i get 460mA via simple usb/PC charging. and it's still charging. (really slow, but charging.)

I'm using a receiver insert. It sits on top of the battery, and has a flap which covers the charging terminals higher up the phone. I'm more than happy with 640mA as I usually charge it overnight. I just don't understand why it's losing charge instead of charging.
if it's charging with 640mA, but still your phone is discharging, then maybe your phone is draining the battery.
try to close everything, such as wifi, GPS, mobile data etc. and then check if it's still not charging.
also, you can try changing to a a different receiver, if you have one
btw, what about normal charging? does it charge normally?

Yes it seems that there's something that's draining the battery faster than the Qi pad can charge it. I've tried a reboot but it made no difference.
"Normal" charging using a USB cable is fine (and quick). I've just set up the Better Battery Stats app to see what's causing the drain while it's on the charging pad.
I don't have another charging receiver to try (only another charging pad, which exhibits the same behaviour)
Ok so I bought official charging backplate for my Note 4 and my wife's S5 along with two separate Samsung mini charging plates. Last night we installed the cases and place our phones on their own pad. Mine was in the living room and hers in the bedroom. My phone was at about 50% before I popped it on the charging pad. When I placed it on there I got the charging beep on the phone, green light on the pad and a little message that the phone was charging wirelessly. Same with my wife's phone. Woke up this morning and the battery percentage didn't move on either of our phones. My phone is still at 50%ish and she reported her phone didn't charge as well.
What gives? Any suggestions? Both our phone show charging when on the pads and the green light turns on which means it is charging correctly as per the instruction booklet.
Check the specs on that pad and see how much it outputs. I suspect it is not enough for these larger phones. It may just be enough that they don't lose charge. I use the TYLT Vu Wireless Charging pad and it charges up over night on my Note 4 very reliably.
you need a high power usb connection for charging pads and a good pad.
i have a choetech, itian and a few others which work well IF they are connected to a high power usb port otherwise they dont work. some of them will flash leds or the phone will say connect/disconnect continuously. they need to be connected to a usb wall wart or computer socket or car cig lighter port directly. a usb hub or old usb 1.0 port will not do. a low power charger will also not do but that is less likely. chances are youre not supplying it with enough power and/or not aligning correctly.
So last night I made sure that all apps were closed and that the phone was exactly centered on the pad. This morning it was at 100%. It's a 2a charger that came with the pad and since there is about 50% loss with these charger I'm assuming it charges around 1a once it hits the battery. Seems to work now. Thanks!
phone shouldnt be centered on the pad. the coils are offset by around 3/4-1 inch from the center so the phone will be a bit high (or low depending on how you place it). obviously if you have the 3 coil qi charging mat/rectangular plate instead of the 1 coil disks/plates then you can just throw it on in anywhere and it will charge.
Wireless charging is a cool way for charge, which is more convenient and help you get rid of the bothering cables. But the charging speed is slower than original cable charging.
So how often do you charge you S8+ wirelessly?
Never
Seldom
Sometimes
Often
More often than cable charge
Mostly
I usually use it multiple times a day. It's on my desk at the office so I just drop my phone there.

Yeah,very convenient to charge in separated time.
I always use my wireless charger when I'm at home. When I'm on the road or staying at a hotel I use cable [emoji5]

anyone know any good 3rd party wireless chargers? for UK all the amazon ones seem to have issues with the s8+ and are not even designed for the s8+ even though they advertise that it works for the s8+ it's misleading.
I use it everyday!
I've never used the cable to charge it.
I'm about to get the official samsung wireless charger convertible 2017 edition. How long are the charge times compared to the fast charger oem?
Sent from my SM-G955U using Tapatalk
99% of the time while i sleep from around 12am to 5am
usually when i charge i'm at 20%
i rarely use the usb charger. only if i need to quickly get to 100% maybe once a month
Daily using my car charger.

Often while in the office.
Mostly wireless charging.
I use it at home but if I'm at work I bring my regular charger.
Only tune I use the cable is in the car. Otherwise, I have a far wireless charger on my nightstand, on my end table in the living room, and on my desk in my office. If I really need a fast charge and don't have time wait, or I want to use my phone while it charges, I'll use my charger from my Pixel XL. I haven't even taken the Samsung charger or cable or of the box. Nor have I removed the ear buds.
Always.
I only need to charge it once a day which is before I go to bed and I just plop it right on my wireless charger. I turned off the fast wireless charging since I don't need it to fast charge overnight (less heat). I gave in and bought the new convertible charger (it finally went on sale for $75 CAD from $130) and it works far better than the older Samsung wireless chargers. The older chargers just didn't seem to work well with the S8 for some reason. I had the charging pad for overnight charging and I'd wake up with a warm phone in the morning. The charging stand I had on my desk and it rarely detected the phone when I placed it on there.
Only once I used and it's slow so cable charging is better for me
cable charging for home. wireless charging for office
We (both my wife and I have S8+ now) both use wireless charging at work and at home, and she has it in her car.
At work I have a Yeesite 3 coil charger that doesn't do fast charging, but sits right next to my desktop pc so is very convenient. I'm not always charging on it but it's super convenient and doesn't interfere with either bluetooth or wifi-hotspot should I be using those.
At home I have an old Choetech wireless charge pad on my nightstand from back when I added a Qi pad to my GS5, doesn't do fast charging but works fine for the overnight recharge. It's a little small at this point and I sometimes don't get the coils lined up, so I may be replacing it with something more appropriate.
I put a Dodocool wireless charger / holder in my wife's car for her, and it supports fast charging (phone declares it's fast charging), and holds the phone just fine. Haven't benchmarked recharge times yet but my wife seems pleased with the setup.
I don't have one of the Dodocool in my car because with the hard wire I get Android Auto integration, with the phone out of the way in a nice little cubby. I have a magnetic cable adapter that has proven reliable, full USB speed, and full charging speed both using a wall-wart and in my car hooked up with the cubby holder I use for my phone that keeps it all safe and secure in the car (even when having a little fun on a back road).
