Nexus Only Reading 1.5A charging

[Caboose27]

I did search through the forums and didn't find anything that applied to the issue I'm having. I bought a 6P off Ebay for a good price, but it didn't come with any accessories. I don't have a C-C wall charger, but I did buy what I thought was a decent one with a C-C cable for my car. The charger is made by Satechi, and the cable is made by Belkin. They both specifically say on the box that they support fast charging, the cable up to 60W, the charger up to 36W. When I tried multiple amp monitors on my phone it only said that it was hooked up to a 1500mA charger. Plugged it into my USB battery pack which has a 2.4A port, same thing. Now, in my experience with computer hardware most of my hardware problems are generally software problems, and I'm wondering if installing Lineage on this thing has eliminated my ability for fast charging. I've done lots of searching (my Google-Fu is terrible) and there's no real mention on if fast charging is up to the hardware or software. Does anyone else have some experience with this and can maybe guide me through some things I can look at?

I know that ampère (app) says Max 1500mah too when I'm connected to my stock charger, but the charge rate goes well over 1500 mah (around 2500-2800 or something). After hitting 60% or something it slows down. I also know that lineage os on the nexus 5 says "charging slowly" on the lock screen, while the charge rate is normal.

I had a similar thought so I drained it to about 25% and then charged it back up. Fastest charging rate I saw was 1250mA.

It's hard to say whether the app, charger or cable is letting you down here. The 6P charging cycle has many steps and it will only pull maximum current from empty to about 30%. Next time you discharge the phone, pull it down to the single digits and then check current again. My stock charger will put out 2.7+ amps when the phone is fully discharged. (I used Accubattery). What you should also know is that the phone will continue to charge for 45 minutes or longer even when the phone says 100%. If you are interested, you can read more in an early Anandtech article. Scroll down to the "Charge Time" paragraph/graph. There is a lot of misinformation around the USB-C standard, and ton of crappy chargers and cables that do not meet the USB-C standard or make claims that independent testing does not back up. A Google engineer named Bensen Leung has been lab testing cables and chargers to try and provide some clarity. For car chargers, he currently favors the Nekteck 5.4A . Lastly, there is much more discussion on chargers and cables in the Accessories sub-forum.

Well, I tried it with the app you mentioned and it said (at 9%) at I averaged a 1350 mA charging current. I almost need to find a charger belonging to someone else that works on their own Nexus and then try it on this one.

@Caboose27
Good you tried a different app to rule out a particular app. My guess is that one of your components is not living up to it's claims. Look for Benson Leung approved cables/chargers and you won't be disappointed. Have a look through the Accessories sub-forum to find good stuff tested and endorsed by other folks. Good luck to you, and welcome to the exceptional Community of the N6P. You chose a good device.

I did look through the Accessories forum, and I found a post about a USB charger that's basically exactly what I'm looking for. But it was a year old and he never wrote if it worked or not, hence me starting this post. I appreciate your input though. Most of the stuff on the sub-forum is about wall chargers, and I'm specifically looking for a fast charging car charger.

See https://www.qualcomm.com/media/documents/files/quick-charge-device-list.pdf (the only not so funny thing is that it doesn't mention Nexus 6p)
Will receive my car charger tomorrow and I only discovered this document today.
Lucky me, the charger is mentionned So is your Satechi.

It doesn't mention it because the Nexus 6P does not support Qualcomm's QC3 or QC2 at all. Hopefully the car charger you bought (you didn't specify) has a native USB-C port or a permanently attached USB-C cable that outputs 5V/3A. Otherwise your QC3 charger will only output a maximum of USB-A which limits you to either 2.1 or 2.4A. A review and test results of many USB-C compliant accessories can be found here.

It does have a USB c cable and outputs at 3A.
Good spot on 6P not supporting QC while chip is a Qualcomm
Haven't seen many reviews. Will give feedback if it exploded.

edit: I finally have had time to test it. Works great.

No worries mate. I have two of those same Tronsmart units. :good:

I bought one and it arrived over the weekend. It works great, and it actually seems to run a tad cooler than my standard two amp charger.

Good to hear
