Hmm so basically you're f*cked when your trying to navigate while charging during summer with a non AC car. I assume it won't keep up and the battery will be losing juice instead of gaining juice. I don't have that problem with my current N5, but I had to buy a specific charge only cable for it though.
[Nexus 5X General] EeZeEpEe:
Summer driving without AC? I definitely don't do that in Florida. ?
[Nexus 5X General] frigidazzi:
Some of is actually use the heater in our cars during winter :eek:.
[Nexus 5X General] EeZeEpEe:
Then close the vent close to the phone. And yes I do use heat in the winter. Of course, not full blast.
[Nexus 5X General] bblzd:
This might seem like an inconvenience for some but really Google is doing us a favor. Batteries won't degrade as fast and there is less chance of one exploding.

Keep your phone cool when it's charging people. I even wait 5 mins after heavy usage before plugging in.
[Nexus 5X General] Darkknight512:
Just for fun, charging on an ice pack. (Only for a a few percent, don't want to overcharge due to the lower voltage at low temp making the phone think the battery is not full yet)
[Nexus 5X General] skippa:
when mine is on charge i can hardly do anything. major lag. i guess that the idea of fast charge... dont touch me
[Nexus 5X General] hokee:
Just wanted to add that I regularly plug my phone in in bed while doin my last bit of reading, you tubing and candy crushing and have never seen any performance or lag issues
[Nexus 5X General] shook187:
This could be an LG thing because I had the G4 and it did the same thing.
[Nexus 5X General] xxc0dvshal0xx:
I've had really slow charging as well with screen on. It doesn't bother me much but it is strange to see that. I came from an s6 and it had no such problem.
[Nexus 5X General] dwang:
So I got my 6p and I noticed that the 6p doesn't have the same problem.

When the phone is charging and the screen is on, it will slow down charging but only down to 1000-1500 mah and not all the way down to 500 mah like the 5x.
[Nexus 5X General] Pandages:
I've been using some older chargers that don't quite have the output to trigger "Charging Rapidly". They continue to charge at full speed while the screen is on. It's interesting how the rapid mode seems to alter the threshold for throttling the charging circuit.

I'm happy to have a 1hr charger (the stock one) as well as several 2hr chargers (my legacy ones) because most of the time, I have the time to wait the extra hour. I mostly charge my phone beside my bed, in the car, or at a desk.
[Nexus 5X General] bblzd:
I thought it was determined that is based off battery temperature. Perhaps the 6p is able to keep its battery temp lower?
[Nexus 5X General] dwang:
The 6p battery temperature seems to be about the same, but looking at 6p thermal-engine.config, it seems to have different thresholds for throttling the charging rate.
[Nexus 5X General] srnoth:
I just performed a rudimentary test and confirmed that the slow charging rate with screen on is directly related to temperature. Basically:

*N5X with screen on & CPU running at max (stress test) & case on = warm back = slow charging (under 300ma)

*N5X with screen on & CPU running at max (stress test) & case off & fan blowing directly on the back = cool back = fast charging (over 1000ma)

Note that this was with the stock charger, with the phone showing "charging rapidly" in both situations. Also tested and confirmed this at various charge levels.

Even worse, under the real-world conditions of using the phone for navigation in the car, I actually had my charge % go down today, while still plugged in to a 2.4a charger.

It seems that this may be an LG issue, as G4 users are complaining of the same thing:

http://xdaforums.com/g4/help/slow-charging-using-faulty-phone-t3116970

http://forums.androidcentral.com/lg-g4/544644-g4-charges-really-really-slow-when-use-screen.html

Sadly this basically makes the phone useless as a GPS in a car - at least during the day when the screen brightness is near full, and the phone itself is in direct sunlight. I personally would prefer for my battery to have a slightly shorter lifetime if I could maintain rapid charging (or at least not a DROP in charge) while using navigation. My previous Nexus 6 could rapid charge during the hottest part of the day, while still running Google Maps & Spotify just fine... so we know it's possible.

Hopefully this is a kernel-tweakable limit that developers will eventually open up to us.
[Nexus 5X General] qwerty12601:
I don't think it has anything to do with temperature. My phone was sitting next to me for 10 minutes idle. Plugged it in to an aukey quick charge...
[Nexus 5X General] srnoth:
Does this charger ever show "charging rapidly"?

The temperature issue seems to affect the phone when in rapid charge mode (it continues showing "charging rapidly" even though the charge level is actually going down).
[Nexus 5X General] qwerty12601:
Nope, it just says charging. It's now at 9 hours till full.
[Nexus 5X General] bblzd:
Does your vehicle have air conditioning?

That's not the stock charger though.
[Nexus 5X General] qwerty12601:
Who said anything about the stock charger?
[Nexus 5X General] srnoth:
Yep but with winter coming up it doesn't really count - at this point it's more of a question of making sure the heater vents are not blowing at the phone.
[Nexus 5X General] nickhell:
I noticed this today, my phone is 2 days old on MDB08L, stock no root, original charger, I was 11 % batt and after an hour or so it was 18%, just surfing. I came here and read and gsam stated it was charging at 281mA. I closed all background apps ( my son played a few games earlier) and after that gsam reports charging at 2669mA. **** it's again at 309mA. I'm on 37°C

update: watching a video it was charging at -106 mA wtf!

Update: https://support.google.com/nexus/answer/6102350?hl=en-GB
[Nexus 5X General] dominican2589:
Of course it will charge faster if you aren't using it. When you are using it, your using some power so all the charging power can't be used just to charge. Some goes to the use. This issue is that compared to other phones, the 5X is extremely slow at charging when using. Other phones slow down too but not as much as the 5X
[Nexus 5X General] srnoth:
That about sums it up perfectly!
[Nexus 5X General] kikikaka:
I use the Google store's USB Type-C to Type-A cable for charging. I plugged a usb current meter to monitor the charging current. If the screen is on, it draws around 600mA. When the screen is off for about 10 seconds, the current increases to around ~1.1A. Unlock and screen on, the current drops to 600mA....
[Nexus 5X General] EeZeEpEe:
Slow charging while screen is on is definitely something I've noticed. There's a thread on it as well.
[Nexus 5X General] axemred:
I've noticed this too, but I'm not too worried about it. It has been an issue with many of my phones starting with the Droid Bionic years ago.
[Nexus 5X General] kparis:
The phone is very slow (performance wise) and the touchscreen becomes borderline unusable when i'm fast-charging
[Nexus 5X General] adichandra:
mine charges normal when the screen is off, but doesnt charge at all when im using it while plugged in. it stayed at 35% for 15 minutes when i was playing with it, no gaming. sucks.
[Nexus 5X General] perrocaliente:
When the screen is on the phone takes forever to charge regardless of temperature. This is all Google and their stupid decisions. The nexus 5 could charge 20 percent in 20 minutes while watching Youtube/netflix for goodness sake. The fact that people think this is okay is ridiculous. No I don't expect the same speeds while using it but I do expect it to charge at least as fast as the phone it replaced. Or close if that's too much to ask. Currently the phone gains nearly NO charge at all while doing something as simple as texting people. This is on the stock charger too! Don 't even get me started on the horrible performance and memory management either.
[Nexus 5X General] EeZeEpEe:
The only time I've noticed slow charging or even a slow discharge while plugged in is when I run turn-by-turn navigation and a video playing during a drive. If I'm only running one or the other, it charges relatively fine. This is with an Anker 2.4A car charger with Elegiant compliant cable.

I wonder if it's an 808 issue. Anyone have a similar experience with other 808 phones?
[Nexus 5X General] Restola:
My mxpe was charging at 1200mah according to ampere with the screen on in my car. Also an 808.
[Nexus 5X General] EeZeEpEe:
With the same scenario, GPS with music/video playing?
[Nexus 5X General] jensvoss1:
I think their must be a bug in the cable or charger. My N5X is charging, keeps responsive and doesn't get warmer (phone and charger) than other micro USB devices

Gesendet von meinem Nexus 5X mit Tapatalk
[Nexus 5X General] Restola:
I'm not in my car now (and this wont take into account any heat-related throttling some people may be experiencing) but with my mxpe plugged into the moto quick charger which came with the phone with navigation running and streaming google music my phone is sitting on my desk charging at 1970 mah.
[Nexus 5X General] Andeh23:
My 5X has the same issue. If my screen is on at all, my charging drops to essentially net zero (with both the Tronsmart unit, or the 4-port Anker unit and the Google USB A->C cable). If I let the screen sleep, it charges very quickly (~20%->full in like 1 hr).

This has got to be some sort of bull**** software setting on Google's part, and is really annoying. While it doesn't affect me in the morning on my commute in, if I use my phone all day and get low on charge, I can drive a 1.5 hrs with Google Maps running and still be at 15% charge.
[Nexus 5X General] Sinergie:
Seems like this is a US only problem, since users in Europe are not experiencing this behavior. So perhaps a hardware issue with the charger?
[Nexus 5X General] 95Z28:
I don't use my phone much when charging, as I usually leave it on my desk at work or charge overnight when I'm sleeping. Today I did happen to be texting while on the charger, and battery still went up 6% during 5 mins or less of use. If your doing anything cpu intensive I wouldn't expect it to charge much, but for light usage to basically stop charging I would say something isn't right with the phone.
[Nexus 5X General] MrHollow:
I encountered something similar last evening but it was weird. I had the phone completely discharged plugged it in and powered it on and it was on 2%. It said rapid charging so i closed the screen and put it on my desk, 10 minutes later i checked again and it was on 3%, panicked a bit and wanted to see what's going. With the screen on it was charging but it was soooooo slow it seemed really weird so i just said, okay this phone is getting returned so i just left it charging on the desk. After it reached 15% after 15minutes or so i checked it again with the screen on and i could see the battery going up pretty fast like it was actually rapidly charging and it went to 18% in about 1-2minutes. 20 minutes later it was already at 40%.

What i can assume from all of this is that it charges slowly if you're really low on battery until it reaches 15% then it goes into rapid charging. I'll give it a try again once it goes below 10% and test the charging output with Ampere.
[Nexus 5X General] nickhell:
I'm in Sweden and it happens to me too.
[Nexus 5X General] MrHollow:
These are my charge times:

10:34 - 15%

10:35 - 18%

10:41 - 26%

11:00 - 50%

11:05 - 56%

11:19 - 68%

11:40 - 86%

11:52 - 93%

11:56 - 95%

12:15 - 100%
[Nexus 5X General] EeZeEpEe:
That was screen on the whole time because that wasn't too bad to get to 86% in just over an hour.
[Nexus 5X General] MrHollow:
Nope, it was closed. If you want i can get some tests done on the next charge with the full run. It will slow down after 90% considerably though, be it screen on or off and it will charge slower with the screen on depending on what you do.
[Nexus 5X General] EeZeEpEe:
Ah okay. I thought that was pretty much what I got with screen off.

Yeah usually just unplug when it gets to 90% because of the slowdown.
[Nexus 5X General] MrHollow:
Okay so back with the results that i promised.

Screen Brightness 50%, Bluetooth Off, Wi-Fi ON (but not connected to any networks), Connected on 4G (full signal Orange - Romania), Location ON. The phone was rebooted before the process.

Timers with the screen on and the settings from the notifications menu on so I could check the percentage, the process was started this morning. No other actions were performed with the phone.

09:41 - 11%

09:43 - 13%

09:48 - 17%

09:52 - 21%

09:58 - 27%

10:02 - 30%

10:19 - 49% (screen was off for a few minutes)

10:26 - 53%

10:31 - 57%

10:44 - 66%

10:53 - 72%

11:03 - 79%

11:14 - 86%

11:21 - 91%

11:25 - 93%

11:30 - 95%

11:34 - 97%

11:39 - 98%

11:48 - 100%

Also i was wrong about the first 15% battery charge timers. From 10-15% at least it will charge just as fast as from 15 to 90.
[Nexus 5X General] Restola:
So 2 hours to charge with the screen on, and a little under 2 hours with the screen off (from your previous post). This tells me the issue people are having with slow charging is some kind of overheat protection as the slow charging seems to kick in when the phone is under high load (GPS + streaming + screen on)
[Nexus 5X General] Ezzy77:
A short test with mine, data from Ampere. Battery at 62%:

Screen off - no data, bt or location: Charging at 2610mA

Screen on (Lux sleep mode and auto brightness): Charging at 20-930mA depending on disabled features/CPU state.

Screen on, running Youtube 1080p over 3G with BT on, location on: charging at 100-410mA

I've been a bit surprised by the power drain caused by the screen as I don't use mine much atm and still it's killing my battery with sub-2h SOT's.
[Nexus 5X General] ITGuy11:
This really sucks. I was using Waze for about an hour while connected to a rapid charger. Battery went from 25-28%. Every other device that I have owned would have charged at least 30% under the same condition.
[Nexus 5X General] EeZeEpEe:
Yeah it's really noticeable with GPS running apps.
[Nexus 5X General] NexusMotoFoshoBro:
Will return. Please don't make me get an iPhone

I just got my 5x last night and woke up this morning at 7 and took it off the charger. Watched some YouTube videos and went to work. Then at 1045/11ish it was already down to 23% battery. Just a couple hours into my first day using my brand new phone. I will definitely be returning it, so many unacceptable things from Google coming with this phone. The charger is also terrible, both ends of the wire have the same end which nothing in life uses so I can't even charge in the car unless I buy the car charger from Google. Starting to feel like apple making me buy new chargers from them. I did a lot of research before buying this phone and no one had said anything about the poor charging capabilities.
[Nexus 5X General] EeZeEpEe:
All reviews have mentioned USB type C being the "future of devices" but it'll be scarce for the first year or so. That's why there's a big thread on USB-A to type C cables so people can still make use of older accessories.
[Nexus 5X General] kasvi:
My 5X does charge extremely slow when screen is on. Hardly at all.
[Nexus 5X General] :
Great i just ordered my 5x now regretting it after reading this thread this is the #1 thing i do charge while using phone especially in the car. Great.
[Nexus 5X General] pnut22r:
Don't fret. It charges slow when battery is high. When it's lower, it definitely makes positive gain
[Nexus 5X General] EeZeEpEe:
But that's not it. Even with low battery, if you have the screen on and active background and foreground apps (turn-by-turn navigation with music/video playing) it's not going to charge fast. For me and my Anker car charger with USB-A to type C cable, it actually still loses charger (just slowly) with that scenario I just mentioned. If I exit turn-by-turn and have video/music playing, it does charge though.
[Nexus 5X General] nexusdingens:
Can confirm

I can confirm the observed behaviour. The charge current is reduced when the screen is on, at least if some component reaches a certain temperature.

I tested different chargers and cables, including the provided wall charger and measured the charge current externally in the cable. Once the phone is in the situation that charge current is reduced by screen on, it doesn't seem to matter if power intensive apps are running. Just the launcher or lock screen is enough to trigger the current drop.

Kernel messages seem to indicate that the current limiting indeed is related to some thermal issue, however I haven't seen any indication so far, which component's temperature is too hot.

After some googling I also came to the conclusion that this may be an LG+808 issue, as reports for LG G4 read very similar.

Has anyone any luck in reporting such issues to google/LG, I mean actually reaching someone and not being blocked by dumb user question first level support?
[Nexus 5X General] N_t_N:
Any chance it's the kernel?
[Nexus 5X General] el_charlie:
I'll just leave this here:

http://www.androidpolice.com/2015/0...use-it-to-throttle-your-charging-speed-a-lot/

It happens more or less on other phones. In my 5X it happens but not that slow. Ampere says over 1.5A on the stock charger.

Cheers!
[Nexus 5X General] andreheitor:
I can confirm the charge current is reduced when the screen is on.

The funny thing is showing to me that was in quick charge and, at the same time, showing 4 or 5 hours for a full charge.

I did a hard reset, and apparently fixed.
[Nexus 5X General] Terabyte:
The reduced charging speed with display on is one thing.

But the problem is, when you use your phone, while it is plugged in (for example for navigation), it won´t charge the phone.

Same is when you play a game while phone is plugged in. Phone does not charge.
[Nexus 5X General] bland.life:
Anyone try Daydream while charging?

Does it charge? Slow?
[Nexus 5X General] EeZeEpEe:
Yeah my battery still goes down with navigation and I have the new Aukey fast charging car charger. ?
[Nexus 5X General] KamariTM:
Hopefully something fixes this. This is very inconvenient
[Nexus 5X General] nicola.mela:
I'm having the same issue.

Phone won't charge at all if display is on (with heavy use will slowly discarge!!).

If this is related to the temperature this is going to be a big problem since the phone is constantly hot.

I'm using the stock charger EU version, does gets better with other chargers?

Edit--

Today I had a chat session with Google about the Issue. Here's what they said:

Looks a bit like a copypasted aswer... but haven't tried the procedure.. i mean.. my phone is 3 days old.. i don't want to hard reset :\
[Nexus 5X General] EeZeEpEe:
Using Battery Monitor, this is what my 25 minute or so commute home looked like with YouTube playing the whole way. Got no charge and stuck at 51%. ? This is with the new Anker type-C car charger.
[Nexus 5X General] 2x4:
what's weird about this is that the lock screen charging text also seems to reflect this now after 6.0.1 when charging via USB A-C, so when I plug my A-C cable to the phone it says charging, but at after a bit it may switch to charging rapidly. Also, it will say charging rapidly when battery is low only, not when high. Does anyone else notice this?
[Nexus 5X General] RTwoD2:
I am having this issue. Stock charger C-C, will not/barley charge while screen on. How is that not getting more attention?!
[Nexus 5X General] 2x4:
probably because its not an issue, but intended design from my understanding to mitigate thermal issues.
[Nexus 5X General] RTwoD2:
Right but my phone is essentially at room temperature. The design is highly flawed and cuts into normal usage. I just don't understand how deva haven't looked into hownto disable this or raise the threshold. It seems like it would severely effect peoples daily usage as it does mine.
[Nexus 5X General] Bei60:
I have this issue also. This is horrible, I'm completely stock since forever and hate it when it happens, sometimes I even discharge slowly while using the phone.
[Nexus 5X General] eduardoll:
I have the same problem... Is there anywhere where we can track this issue? Device is plugged in, screen on and battery is draining

Enviado de meu Nexus 5X usando Tapatalk
[Nexus 5X General] 2x4:
The fact that charging is now at 5V/3A means more power is coming into the phone, which means more heat, so I assume that's not something devs can fix. I'm not a dev tho so I may be wrong.

One thing you can do is change the thermal throttling temp with a kernel like EXkernel, which may affect the charging speed since the reason this throttling is done is to prioritize your performance over charging speed. Again I'm not a dev tho so maybe go suggest this at the kernel thread
[Nexus 5X General] katetimosoy:
Is there any workaround for this? Cant believe that their QA didn't find this bug.
[Nexus 5X General] Majin Aiman:
U should use the higher output voltage to increase the charge speed of your phone. 2A or above is recommended.
[Nexus 5X General] EeZeEpEe:
But it doesn't have to do with output of the charger. Even with the stock one it can be slow or not charge when having the screen on.
[Nexus 5X General] Majin Aiman:
Then please check your battery. Normally, even phone with 3500mAh or above can be accelerate it's charging speed by using larger output current. Boost battery if necessary.
[Nexus 5X General] EeZeEpEe:
Check my imbedded battery?
[Nexus 5X General] nizarnoor:
I'm having the same problem. It's so annoying.
[Nexus 5X General] asc366:
Pretty much the same here, in the Netherlands, Europe. Subscribing to see if there's any updates for others.
[Nexus 5X General] gerrysnaps:
Indeed, I've had this happen on my Nexus 5 and older Nexus phones before, so not surprised that it will not charge quickly while running navigation or playing movies that need the screen to be on as well as other battery draining devices. This seems normal to me. I have changed out cheap car chargers that fail to charge my phone even at the expected slow rate, but that is a different discussion.
[Nexus 5X General] EeZeEpEe:
Thing is for me and my GS5 or even GSIII, I never had a problem charging and using Google Maps with music playing in the background.
[Nexus 5X General] gerrysnaps:
I know GSIIIs, paired with the wrong charger, can, in your use case, draw more power than the car charger can provide and the net effect is nil or the charge drops but slowly. Paired with the right charger, it will charge but it will never charge as fast as when the screen, GPS or bluetooth module is on. As simply pointed out, you are putting a lot of load to charge the battery when using all of the most demanding components, so that will absolutely impact how quickly you can charge.

For some of the cases on this thread, I would also check the charger and cable. If you're using a legacy usb-c adapter with a usb-a charger, don't expect the quick charge function to work necessarily on a fast car charger even if it says 'Charging rapidly' on screen. The 5x doesn't support Qualcomm quick charge. I have switched my car charger for a Tronsmart 33W with USB-C and USB-A quick charge 3.0 ports, and get reasonable charging rate out of it using USB-C, even with GPS, screen on and Bluetooth streaming audio from Spotify on mobile network. Prior to getting that charger, I would need to use a fast charging ASUS ZenPower 2.1A power bank with a compliant A to C cable to charge at reasonable rate in the same use case.
[Nexus 5X General] EeZeEpEe:
Good point. I also feel like it depends on how much battery the phone has makes a difference too. I feel like when it's below 40% I'm either at even not getting a charge or a slow trickling discharge. But above 60% or so I have a decent charge. 40-50% not really sure. In both cases I'm talking about using Google Maps, streaming Google Play Music, and using Bluetooth. This is with my Aukey charger.
[Nexus 5X General] kuosi:
Any solution about this when screen on and not charging?
[Nexus 5X General] asc366:
Not yet here. Marchpatch hasn't fixed the charging issue.
[Nexus 5X General] EeZeEpEe:
Yeah still charges at the same rate I was getting prior to the update.
