Lost 'Fast Charge' capabilities - Huawei P9 Plus Questions & Answers

As the title says, I suddenly lost the ability to fast charge. Used to work fine, then one day (about 3 weeks back now) I plugged it in, with the included charger, albeit using a micro usb with a usb-c adapter, and it no longer said 'fast charging' on the lock screen. Note that this combination of OEM charger + cable with adapter, had never caused any issue in the past, even as late as that previous night.
Have since flashed it up to Nougat (.362) and back to every other firmware in between (.170 which it originally came with, .180, .190, .202) and none of them work.
Have also tried a second original charger which I had bought, and had previously worked with, but no luck, nor with any variety of usb-c cables, or cable with usb-c adapters.
Any thoughts?
It charges perfectly fine, just without the notification. Have not had a chance to fully drain the battery and time it (last time it hit around 45% in 30mins, so I can use that as a base).
Only thing I can think of, is it somehow 'shorted' (for lack of a better word) something inside, but you'd think it would affect charging in general, and not just the fast charging bit.

Vehicle chargers won't work...

Okay, I'm stumped. I'm already getting a replacement device from HTC under warranty so my problem is solved, but like many of you, I HATE NOT HAVING AN EXPLANATION FOR THINGS!
I'm also wondering if anyone else has had this problem? About 10-Days ago my Kaiser (Tilt) stopped charging via the automotive charger. The A-C charger works fine, but the vehicle charger sent to me with my device from AT&T completely stopped charging my device. I went to the AT&T store & bought a new charger, It didn't work. I changed power points, & cigarette lighter in the vehicle &, it wouldn't work. I tried the charger in the vehicle of two different AT&T sales guys & also tried multiple chargers, & it wouldn't work. Is there any reason why the unit would lose it's ability to charge via a vehicle charger while still retaining it's ability to charge through USB to computer & through the A/C home charger? It seems to me that if the charge portion of the MB was fried, then all charging would be affected.
So how can my device charge fine through all means EXCEPT the vehicle charger?
Again, AT&T is sending me a new device, but I hate not having an explanation for the problem, drives me Nucking Futs!!!
Any ideas, anyone?
Thx!
I dont want to sound rude but have you checked your power settings?
Under the "Advanced" it has a option for "When device is turned on, do not charge the battery when connected to the PC."
If this is ticked it will not charge via the in car charger.
It's a known issue, not just with the Tilt
I had the same problem with my Axim X50 and X51v.
The original sync/charge cable wouldn't charge from the car's lighter, while non-branded cables did so without any problems at all.
This happened with other Axims as well, so I know that it wasn't a defective unit.
I then purchased an HP Ipaq HW6910, and encountered the same issue with my wife's Mazda 5 - the HW6910 woudn't charge if the cable was connected to the charger, when I started the car. It only worked if the adapter and cable were disconnected while staring the car. This did not happen with my Mazda 3 or my Mitsubishi.
And another thing I discovered, is that some cables are not designed for use with car chargers, but they work perfectly with AC chargers.
I bought a couple of retracting sync/charge cables for my HW6910, they worked only when connected to the mains. But regular cables worked perfectly with both power sources.

OF COURSE I DID.
Yeah, It charges fine from the PC, & from an A/C source. But the HTC TYTNII car charger that came with my device, as well as replacement car chargers don't work.

Funny, I just ran out to the truck & grabbed one of the guys Blackberry chargers & it looked like it was working. But SK Tools reports an even bigger (negative) amp draw (like discharging twice the normal rate). So with the BB charger it dischages even faster. Maybe reversed polarity Guess I should've checked first. That's a moot point now though as I await my new unit. Weird though.
Well i was using a BB charger that worked fine up until this morning. i bought my phone when it first came out so it wasnt easy to find a charger made for it at the time. i never had a problem until today. i also noticed that the Usb terminal on my device was bent. i called htc but they charge way too much to fix it. i have no idea how or when the terminal broke but it does still charge when pluged into pc or into the wall. ill have to spend $80 to have ppctechs fix it.
wassup, i`m in SF Cali, I had a att 8525 that was doing the same thing. I assumed it was the phone when it 1st started happening. After a week or so it was bothering me so i started playing with it trying to figure out if it was a setting, bad flash, or hardware. I noticed that if the phone was off it wood charge but not if it was on. I started flashing my phone and testing (for trouble shooting purposes) and for the first 2 or 3 roms problem still existed, then one of the roms i flashed to would turn on the back light as if it was charging but no LED or charge, when this started happening I realized that if i turned my fone off it wood start charging and continue to charge when i booted the fone back up. So if when i got in the car i pluged in/ shutdown/ waited like 45 sec or 1 min. / then booted it would temp. fix the problem for as long as my fone was on the cable. At some point after that many weeks/roms later i noticed it was working correctly again, So I had decided it was a glitch in the rom, But i`m not a Dev. or fone guru so I really dont know what it was, but hope this helps someone.... PEACE!! ~bboyphrog1~beatz`n pieces krooh~

The slight diagonal slant on the bottom right? It's supposed to be like that. All AT&T Tilts (and I'd assume TyTN II's, but I've never had one to compare) have a mini-usb port that looks that way.
i looked at a 8525 and the usb terminal was straight. i even took a pencil and straightened mine out. it should be bent. that wouldn't make sense because the charges slot is not bent. i think the problem is that one side of the terminal is not soldered to the board and can easily be broken. in another thread 3 people have the same issue. as far as the car charger goes ill do some testing but until today it was charging fine while the phone was on.
this issue is known ,it even happens with the htc tynt.... by simlpy rebooting while in the charger it starts working again ..at least with mine.
I've had the same problem. I went to the lcoal AT&T store and they said they never heard of it so I thought it was just me. It looks like many of you have the issue. I wish I knew what it was. It was really bad with my 8525,
i thought Faria developed a cab to fix this issue in the hermes forum? might be worth having a search for it and when i get home i will see if i have a copy on my pc.
any of you guys get anywhere with this? I have exactly the same problem. posted in a couple of other threads actually.
Not sure whether the usb port is damaged, but it's certainly is slightly "down" on the right hand side.
It charges perfectly on the mains and perfectly from usb, but not in the car.
I have used a normal car charger, spent £50 on a Carcomm powered mount and tried one of the separate chargers that you plug the standard mini usb cable into. Nothing works. This is driving me crazy (if you'll excuse the pun!) a the primary reason I bought the Kaiser, was for GPS.
Thanks
well i also just found out 2 of my minisync cables dont work anymore. 1 of them still charges the phone but neither of them sync the phone anymore. it still syncs fine through a normal usb cable.
I am using a moto Razr car charger and it works fine so far.
Okay, confirmed on my replacement Tilt: The USB port is arrow straight. Someone earlier mentioned it being lower on the right side & indeed my DEAD DEVICE was as such. Looks like a bad job of connecting the port to the device.
NOTE!!!!!!
It's a good idea to take a look at your charger before you plug it in to make sure the charger USB connector is not bent or mi-sshappened.
i have the same problem i went through 4 att car chargers adn 5 phones. They are crap. Its not the phone its the charger if you play with it you will see that it comes and goes. The end tip on the charger is bad doesnt make a good connection. i have yet to find a good car charger.
Mine stopped charging using the car charger supplied and a brodit. A friend's kaiser charges OK with the same chargers.
No-one has mentioned it in this thread, but my phone, shows "charging" in the battery control panel and the LED lights up to confirm this. The percentage charge value decreases as though it isn't being charged!
As others have done I noticed that the corner of the plastic centre of the connector nearest the reset hole was slightly bent and I assume (though can't remember doing so) that I missed the reset hole with the stylus tip and pushed it in. Menu driven resets for me from now on!
HTC Europe didn't know anything about this fault, so seem to be happy to repair / replace it under warranty. It's with them at the moment, so I'll have to wait and see.

Please let me know the outcome. mine is getting worse by the day.
Now I'm confused.
Because the device charges over USB I just assumed it would draw <500mA (the max output of a USB port) but the specs say it draws up to one amp.
Having owned a high-drawing device before (Axim x50v) I know that trying to pull this out of a USB port can blow your motherboard. So are these safe to charge over USB??? How does the device know whether its being charged over USB or mains - are there different charging pins on the connector?

Alternate Chargers

Is there anyway to get this thing to charge off of a regular mini usb cable? I really don't want to have to worry about a separate charger when I go places.
Is it the cable that matters or the transformer it connects to? (I could test this but I left mine at my bro's house; hence wondering if there is another way to charge it right this second.) I have tried a few different computer systems and even the original nook charger but nothing charges this thing.
What gives?
it charges
The original nook charger (and any usb cable) works however the NC doesn't indicate it is charging. That's been my experience, ymmv. I'm not sure why the battery indicator doesn't work but maybe it could be addressed in a custom rom.
Agree, and I've used my BT headset charger to charge the NC successfully as well. (micro USB)
afaik what I read on MobileRead and the B&N forum indicates that normal microsd charges the NC, just slower (and no charging label). But I'm not 100% sure here, haven't tried it for myself.
Yeah, very slow. It went from 10 to 68% overnight. Hopefully it will top off while I am at work.

Weird battery/moto charger issue

I bought a used nexus 6. It's in good shape. I immediately installed twrp and flashed cataclysm (my fav). This was all done on day one. I began using the device as normal. Upon plugging the device in to the charger (moto quick charger) I noticed it was charging VERY slowly. I checked the battery usage menu in settings and noticed that it said "charging over USB.". I was plugged into the wall. So, I thought, alright the guy sold it to me with a borked charger. I tried my old note 5 quick charger and it seems to work fine. Then, just for additional trouble shooting, I tried using the moto charger on my wife's lg g3. It worked fine. Seems the issue only happens on the nexus 6 with the moto quick charger. I searched with Google and found:
https://m.reddit.com/r/nexus6/comme...is_charging_slowly_says_it_is/?ref=readnext_3
Anyone know anything about this, or knows of a fix? I can use my note 5 charger, but my obsessive and anal tech ways keep me from just letting it go.
Thanks in advance!
I'm having a similar issue with two different chargers:
The Included Charger (the one that comes with the phone)
and
Aukey 12W / 2.4A Home Travel USB Wall Charger Adapter
http://www.amazon.com/gp/product/B00Q873I3K?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s01
+
Monoprice 6-Feet USB 2.0 A Male to Micro 5pin Male
http://www.amazon.com/gp/product/B003L18S0E?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00
In my case, what happens is that the phone intermittently start and stops charging while plugged in. Not sure if it actually slows down the charge process though...

Slow Charging - Max Charging Amps?

So I recently picked up a T813 to replaced my Nexus 7 (2013), I've had a few weeks now, and as with all my devices I slow charge it. This tablet generally took ~30 hours or so to charge at 0.35-0.45 amps, but I didn't think anything of it. This week I went on a trip and plugged it into a charger that can output anywhere from 0.8 to 1.8 amps depending on the port you are using (all the current ratings I'm listing are what I've measured, not what the devices are rated). My tablet said "Charging" at first, but then once it hit 75% all it would say is "Charging Slowly" no matter what. Now that's all it will say. Sometimes after a restart it will say "Charging" briefly, but then it goes back to "Charging slowly". The charger I was trying to use was an Anker product, so not a complete "no-name" charger.
I did some more checking and it appears my tablet has an upper charge limit of 1.5 amps using even the factory charger which is rated 2.0 amps. That same factory charger plugged into my Nexus 5X outputs 1.88 amps. Anything less than 1.5 amps, my tablet behaves as the rest of the devices. If I plug the tablet into a power source that current is limited to 0.5 amp, using the same cable, using an Honor 5X, and the Tab S2, both draw the ~0.5 amp.
Now the "Charging" and "Charging Slowly" messages were on Lineage, however since I have returned home, I and done all the subsequent testing, I have used Odin to return completely back to the factory Samsung software. Right now I have some videos playing to run the battery down, and am planning to trying to charge the battery all the way up using the factory charger to see how long it takes. If it also takes 30 hours, I'm going to assume it has to be a hardware problem?
Anyone else have any ideas?
My T813 arrived with Nougat on it. The only Odin firmware I could find that would successfully flash was a Marshmallow so I let videos play overnight (which did actually play overnight surprisingly!) to fully drain the battery. This morning I started charging the battery with the OEM charger, and from fully dead to 100% it took roughly 4.5 hours. So I would say this is normal from what I've read. I would say this rules out any hardware issue.
My next test will be to find a flashable Nougat OEM image as it doesn't want to update itself. Then see how it performs then. I'm starting to wonder if Samsung changed something in the firmware to make it charge slower on purpose just to prevent any "Note" like issues from happening? Finally then I'll have to also go back to Lineage, as I don't plan on using it at all with the stock software, as it's quite unbearable. There's a reason I only buy devices that Lineage is available for.
So after updating to Nougat, and letting it update, then fully draining the battery again, which again took overnight, it seems to charge even faster. This time from 0-100% taking just under 4 hours using the OEM charger, at roughly 3 hours 45 minutes.
I'll put Lineage back on it tonight, however this definitely calms my concern that I had a hardware issue. It's definitely fine. I'll see what kind of charge time I get with Lineage.
It charges with ~1600mah
I've had slow charging issue twice. I sent it in the first time and Samsung sent me a slow charger (not fast charger) to use. Worked fine for about 10 months. Once I update to Nougat, my charging became slow again.
Seems like many people have slow charging issues with this tablet. I have the Verizon tab s2 9.7

Yeah this is what I've noticed. This seems to be about the upper boundary. Despite being shipped with a 2 amp charger. I did reinstall Linage, and it charges fine with the OEM charger, so it's not a bug on their end, or a hardware problem for me. With LOS and the OEM charge it's still ~4 hours to charge with is what I would expect roughly based on my other tests, even though LOS still reports charging slowly.
I think my problem early with the 30+ hours of charge time was related to the hub I was charging with. I have been having issues where I would wake up and my phone wouldn't be charged at all. Most nights it would though, so I figured my cable was starting to go bad. Swapped the cable and same issue. Measured the current on the ports, and it was far below what it should be on a USB port, the charge ports were getting 0.18-0.2 amps, the regular ports were 0.2-0.3 amps (not sure why the regular ports were getting more). Then I noticed the power adapter was not plugged in all the way into the wall. After plugging it in all the way the current on those ports returned to normal. This honestly doesn't make any sense to me, so it maybe time to replace that hub. Either way, I know the problem is not the tablet, which calms my fears about it, since it was the new piece of hardware.

charger/cable issues anyone?

Since 2 months ago I began experimenting some weird behavior while chargingv with either charger qc30 or 5v2a I don't get fast charge, or it's difficult, I believed it was an an issue with either cable or charging port, first I tried some cables it barely bring back fast charge, lately even with new cables neither fast charge, I swapped chargers nothing, finally I replaced the charging port with one new, same thing but stronger plug, I noticed when I plug the cable either end it recognize it and begin charge for a second or two, then drops charging, only way to charge until now it plugging the charger to an anti-noise USB extension I have.
