Hello, can anyone else reproduce this bug?
When my phone is charging and it goes to 100% it will still have current flowing thru it(AccuBattery) even tho the charging LED is off and if I ,in that moment, disconnect the phone from the charger and then reconnect it to the charger, the current goes to 0A? The battery voltage at that time is about 4.45V, is it overcharging?

No, it's not. As an Electrical engineer, i can tell you with certainty that there is nothing wrong with the behavior described. The feature wherein a mobile device stops charging and uses only current provided by the charger is called Power Passthrough, Which only a handful of devices can do right now. Example for that is the Asus rog 3.
Regarding the voltage situation, accubattery only refreshes the charging state (status inApp) after you disconnect it due to system limitations. A clue for this limitation you can find in accubattery itself; when you want to measure the battery capacity and it says disconnect the charger first. So no worries you phone is fine :good:

Yeah but that's the thing, when the charging led turned off it was still drawing about 1A of current until i reconnected it and it just didn't draw anything, shouldn't it restart drawing if it drew it before disconnection? I mean it's just kinda weird that it started powering the phone directly, instead of charging the battery, only after reconnecting the cable...

I woke up to find my SDA powered off and unable to power on, which was odd considering it was plugged in to a (Motorola) charger.
Since the orange charge light doesn't come on at all, I suspect it's just a dead battery. I've touched the battery contacts to a battery tester with no response - as if the battery is totally dead, which is promising. However, I can't be sure I'm doing it correctly since I've never tried this on a battery I know is working.
There are 4 contacts on the battery, and I'm wondering if there's more to it - like needing to have 2 contacts touching the positive lead and the other 2 touching the negative lead.
Can someone try testing their battery and see which contacts give a live (charged) result?
Thanks

Normally you shouldn't try to use chargers not designed for your phone. What has probably happened is that there wasn't enough current output in the charger, and it completely drained your battery. Your battery is probably fine. Get a proper SDA charger and try charging it again. You can even take it to a store and ask them to plug it in for 15 minutes while you browse the new phones.
Yeah - I lost the original charger, but I've been charging with this Motorola one (output 5V / 550 mAh) and via USB for the past 6 months without problem. I still think it may be the battery because it was at 50% when I went to sleep.
What are the output specs of the original charger?

The stock HTC charger (model ADP-5FH K) has output of 1A at 5V. But if you had no trouble charging before it shouldn't be a issue, unless the charger/battery is faulty.
If you have a multimeter you can verify this. To check if your battery is charged place contacts in (+) and (-) contacts on your battery and it should show ~3.7V. I just tried this.

Thanks, silencer. I don't have a multi-meter, but I was using the battery tester as a way to gauge whether it was putting out any current at all, and it sounds like it's not. You were testing the 1st and 4th contacts?
I have read elsewhere that if your battery goes below 10-20% you won't be able to charge it with anything but the stock charger, so I think that's the problem, but I'll probably order a new battery as well just in case.
Yes I check the voltage between first and forth contact. What sort of battery tester are you using? Is there a digital read out display?
You can also try a USB to mini-usb cable to see if the battery get charged. From what I can remember USB ports are designed to give 500mA at 5V, but I have charged my phone when it was flat using a USB cable.
To follow-up in case anyone has this problem in the future: I ordered a new original charger (ADP-5FH) off eBay and with it, the phone's orange charge light came on right away and after giving it a full charge my phone is back up and running.
I'm inclined to think that it's not the difference in mAh of the original charger (1000mAh) vs USB charging (500mAh), but that there is something unique to the original charger which can "turn on" the charging when the battery is completely dead - perhaps something communicated by one of the extra pins in the mini-USB connection.
Hello,
When I charge my Nexus 5, the battery icon keeps on showing it is charging even so the battery is at 100%. Also my USB charger (not the one LG one) indicates that the device is still charging. Is this normal ? Would this damage the battery ?
Thanks
It's normal.

Thanks ! (But i just find this weird as I expected a device to stop at 100%)
I understand what you're saying but it's not a charging icon, it's a connected to power icon. If you were to use something like the dashclock extension it would show that it actually stopped charging once it reached 100%
Thanks for the reply.
The thing is that I have this charger http://www.portablepowersupplies.co.uk/portapow-quad-usb-mains-charger/) and the LED indicates charging (albeit I did not measure the current ).
Nice unit!
Are you connected to WiFi while charging? I had the really bad battery drain issue while connected to WiFi after the 4.4.2 update. I lost about 30% of charge after 4ish hours while connected. Currently I'm at 92% after 3 hours.
The WiFi battery drain could be causing your phone to not fully charge or at the very least make your charger THINK it's not fully charged. No harm should come of it either way but it's always best to pull your phone off the charger once it gets to 99-100%
Thanks for the reply. I had Wifi activated; it might be the reason.
My wireless charger LED didn't shut off when my N5 was charged in a powered off state. Usually it does once the battery is full.
That said, I don't think it's over-charging the battery, as that would be really bad

Don't worry about it. This isn't the 2000s where constant charging is an issue.
Just tried with the Wifi Off. My USB charger then indicates that the unit is not charging.
Thanks for the replies and great help.
Don't worry about it. The charger isn't the thing that determines how charging is handled, it's all done on the phone side. The phone knows how to take and stop taking power.
In the case of the Nexus 5, it most-likely stops charging the battery but continues using the power from the charger to actually power the unit (thereby no-longer using the battery to run the device, but not charging it any longer).
Anyone successfully using this? How have you set your charging thresholds?
For anyone not aware, the module allows your phone to stop charging once it hits 100%(or a specified percentage) and will start charging again at another specified percentage. I'm wondering how safe it is for the dash charger. Won't that power it is sending to the phone have to go somewhere? I understand the charger is doing some sort of energy conversion for the OP6 that other phones do internally at the battery- hence the OP6 doesn't get as hot while charging like ither phone's might.
Thanks!

It still has a governor to tell it to stop charging and switch to AC power after 100%. Dash charge is most effective to 60% then it dips off to protect from overload. It would just alter the governor to a lower value to switch to AC power sooner. From using a 3t for 2 years, charging every night, it didn't impact battery life too much anyway, so degration isn't a big issue, if that's your concern, unless you will keep this phone for 5+ years. The module will just give more control that you can't normally access. You can set the charge to stop at say 85% and it could keep the battery healthy for longer, in theory, since it is not always filling the battery with energy.
i have set my mcs to 65 35 via terminal, works like a charm.

Still, the actual charger is inside the phone. Otherwise, your battery would explode if you left it charging on USB or generic AC Adapter.
When I talk about charger, I really mean the phone's built-in electronic component which controls battery charging.
Many kernels have a software switch for toggling charging ON/OFF on demand, and OP's are not an exception.
In theory any Android device could have that, since the Linux kernel can be customized beyond imagination.
When you set that switch OFF, the charger simply stops pulling power from USB/AC adapter. At that point, since there's no load, the power source takes a break.
So, what's the take home message?
You can safely use MCS on One Plus 6.
There's a beta version which is good enough to use as a daily driver.
Don't hesitate to ask questions on the official Thread.
Hi guys,
I haven't been able to charge my phone properly for a while - after reset when I plug in the original charger, it charges fast, when I unplug it and plug it back in, it charges slowly. When I unplug it again, it still shows the charging icon forever but it won't charge when plugged in. Factory reset doesn't help. The phone also randomly shows the USB moisture message even though it never got wet. Changing cables and power sources doesn't help.
Build MHA-L29 8.0.0.375(C636)
Thanks for any ideas!
Blow out the USB charging port on the phone. Also, use a toothpick to GENTLY clean out the port of lint and dirt.
And use app that tracks your charging speed. Try ampere In playstore.

Thanks for the reply. I tried that already. Is it possibly a battery issue? I wouldn't mind replacing the battery, which is cheap rather than replacing the phone because of such nuisance.

Ampere clocks in at -250 mA after reset. Goes to around 1800 when plugged in to a third party charger, which drops to around 300 mA when unplugged (phone indicates that it is charging). After reconnecting it goes up to 1000 mA. I don't have my Huawei charger at work but it's similar - at first plug in it charges fast, after reconnecting it switches to the slow mode.
You should use your original charger. And see if supercharge is working. If not. Give it a shot in a service center. Theyll fix your phone for free if you still have warranty.

Well, before replacing the battery, try this:
- turn phone off
- connect to original Huawei Supercharge charger and charge up until 90% or so
- disconnect from charger and turn on
Use the phone as you normally would until around 35-40% remains, then try connecting the charger. If the issue persists, I still believe it is a problem with the charging circuitry rather than the battery. Especially if we take the moisture in the USB port message the phone shows. Replacing the USB charging circuitry should not be a big problem AFAIK, it is connected to the motherboard with a snap-on connector, replacing it should be easy as disconnecting the connector, removing the circuit with the port and placing the new one in.
Yep, I guessed it: https://www.youtube.com/watch?v=4avHFWjsz4k
Are you having issues where the phone is displaying 30 or so percent battery remaining, but the phone shuts down?

That's a great point. I didn't know the USB circuitry can be replaced by itself. I don't have any issues with the phone switching off. It uses the battery all the way down to 1% or so. I don't see any erratic percentages. I'll replace the part and update you on what happens. Thanks!

Yup, that was the problem. Easy fix. Thanks for the suggestion!
Make sure your microphones still work. I had to replace my USB charging board (which also contains the mics) recently and the first one I tried had a bad mic. I could make phone calls just fine, but google assistant couldn't hear me. I got a replacement and both mics were fine.

I wish I could close this thread but a lot of weird stuff happened since I "fixed" the phone.
Since I bought the battery before I was told it could have been the USB board, I replaced the old battery too. The first charge was smooth and I drained the battery to 0 as recommended. I plugged it back in and it charged to 5% and stopped. I noticed a chemical burn smell that I later realized was coming from the USB circuitry. At this point there was no way to charge the phone but when tried to turn it on, I still saw the red charge icon. I opened it up and put the old defective USB board back in and I was able to charge it. Throughout the day I noticed weird battery drain that I saw recently before the replacement of the USB board. As usual, I tried to restart the phone to fix that but it won't turn on. The battery was at 85% when I shut it down. When I try to turn it on, it won't even show that red charge icon. Nothing. I can't put the old battery back to see if that's the problem, because I bent it during replacement.
Could it be a battery issue this time or is the phone just dead at this point?
Hi,
We are facing what seems like a weird charge current limiting behavior of the Android (or maybe Pixel?)
We are using Pixel 3XL as a sort of an embedded kiosk.
It is connected to a Windows10 PC (Intel NUC 8th Gen Core i5) through a powered USB hub. We use ADB to control the phone and our app from the Windows PC.
Our app running on Pixel is consuming a fair amount of juice, but the Phone is still charging while our app runs ... except ...
When we just plug in the Phone, and run the app - all is well, phone charges and reaches 100% fairly quickly. Then, if we leave it running (our app is still consuming the usual amount of juice) - sometimes, after many hours of being plugged in, the phone starts discharging while plugged in. If we reboot the OS on the phone, it starts charging again (with the app running still).
Another easy repro of the weird discharge behavior: If we let the phone charge fully to 100%, then, start our app - it starts discharging rapidly. Now, if we were to charge it only to say 70%, and started out app - it would keep charging, until it reached 100% and could stay there indefinitely. And then again, if we just kill our app, let the phone sit a bit, and start the app again - it starts discharging (reaches 0!)
I should mention that it does not matter if the USB hub is powered or not - once the phone starts discharging - it does not matter how much juice is available on the hub.
Any thoughts? Do you think this an Android thing? Or a Pixel 3 bug? ... I least suspect it to be a "Windows bug", but appreciate any suggestions!
Thanks!
The phone charges more slowly as it approaches 100%, I believe. It is my understanding that you cannot achieve rapid charging with an A to C cable, only C to C. I see you said it's on a USB hub but doesn't specify if it's an A/C or C/C cable. If it's rapid charging the charge is likely enough to overcome the draw of the app/screen, but once it slows down at/near 100% it charges more slowly and can't overcome it anymore? Could also be thermal throttling or similar if the app is that intense?

Good points. It does not appear to be related to temperature. The phone is at ~42C throughout, and happily charges. Then it reaches a 100%, and if we stop our app, then start it - it starts discharging. Only full reboot helps (our app restart does not matter). The cable is A to C, but again, even with that connection, it would charge 10-15% an hour with our app running until it reaches 100%, and the whole "throttling" thing starts, which can result in discharge to 0.
