Phone confused about charging - Huawei Mate 9 Questions & Answers

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.

Thanks, good idea.
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?

USB port damaged?

I have looked around on this topic before posting, but nothing applies to what im experiencing
Up until this morning, I haven't had a single issue with my USB port or charging in general.
I clean flashed Purity KitKat, flashed compatible Uber kernel and installed my apps as one usually do, and let the phone charge for a while. A few hours later, I realized my battery was at 0%. I started panicking, looking for a USB replacement part, which I found for about $12 on Amazon. I decided I would download GSAM battery monitor to see if there was an issue with my charging cable.
What I saw was the mA flow was acting erratic, sometimes shooting from -700ma (yes, that's negative 700) all the way up to 1800mA. Even by just rotating the screen, it would drop instantly. . The phone charges, but a little at a time. I disabled KSM and fast charge which seemed to have a positive effect.
I'm not sure what caused this, or how to fix it, but I've attached a couple pictures to give you an idea of what I'm seeing. If it is in fact the USB port, would using a Qi charger be a good option or should I just go ahead and dismantle the phone and replace the USB port?
Note: windows still recognizes the phone and I can send files from the computer, and the charging bolt is showing.
Have you replaced the cable? Far more common for the cable to crap out then the port. Cheap or broken cables will appear to work, computer will detect phone and even display a charging indicator but it won't actually charge. Had happened to me in the past.

Yeah I've tried numerous chargers including my car charger. They all charge, but it took 12 hrs from 0 to 100

Try flashing the stock rom to rule that variable out. If you want to be sure that is the usb port you could try with a wireless charger as it could also be the battery, you can find a new one at the same price range of the port.
It does seems a lot like what happened when both the stock charger and the cable were damaged. I tried to charge the phone and when disconnected it had less charge.

Z3 D6603 does not do anything anymore

Hey Guys,
i recently did change the Display on my D6603 Z3. It took some for the Display to arrive, so i did not charge the Smartphone at that time.
After changing the Display my Phone only gets a Red LED when plugged into the charger but none of the Reset combinations seem to work.
Also does the LED stop after sometime. Anyone has an idea what could be wrong ? Its a constant bright RED light.
Mine did a similar thing if I remember correctly. The LED should at least change colour when charged, stays red= battery not charging. I changed my battery and has been fine ever since even though it is a cheap one off ebay!
Presume you've pressed the tiny yellow reset button that's next to the sim card.
Just stick a new battery in it's not like it'll ever be waterproof again! lol
jim
I did change the Battery but it seems like somethin is wrong with the USB Port. I got the Z3 Running now but suddenly i am not able to load it anymore. Its on and i have 40% Battery but when i put in the USB Cable nothin happens. Also its not regocnized when putted into the PC. Any tipps ?

Try charging via the magnetic port.
I tried that. It does not really work. When it connects then disconnects then connects again for about 15 times or more . The LED blinks orange the whole time. after that it starts chargin but it charges 10% in 6 hours
what i also noticed it that i wont get the message anymore that when the cover of the usb plug is unplugged.

what are the Battery Chips ? It is an original Battery from another Z3. I have 3 here now and got the same problems with all of them. It seems like that the charging power is not constant but it charges then stops then charges. Repeats like 2 times per second.
welleither u should try to getg an 2A charger and proper cable and retry. else ur usb port (z3 ones) might be defective

xperia XZ charging problem

Hi, I am a novice in phone repairs though I have successfuly replaced the screen and charging ports on a samsung s6 and note 4.
I am requiring some expert advice on this problem, I was given an XZ from my friend with a cracked screen and charging problem, the charging port became temperamental and failing (at least I think it was that) and eventually wouldn't charge at all. The charging port was handled a bit harshly toward the end, for example the charging cable lifted up and down to try to get a charging response.
Anyway I ordered a screen/digitizer and charging port flex for it, and fitted them, following a guide. Before this, the phone had around 2% charge. After the repair, I switched it back on and conncted the charger, the screen was fine, however there was no response from the charger. The phone then ran flat and eventually ran flat enough to not be able to show the "low charge" symbol when the phone is off. Then after plugging and unplugging the cable (via USB in the pc) it would charge for what seemed a second then stop, the red charging notification light was lighting up. The same happened with a wall charger. I then stripped it back down and back together again. This time there was no response if I remember right, then I connected it to the wall charger and left it for 3 hours or so. I went back to it and it had charged up to 15%.
Now i'm at the point where the phone is working, it's on 90% now, but it charges very slowly, around 60-350 mA per hour on Ampere app. So a full charge is around 12+ hours. This is in the wall socket with a fast charger. Additionally, it takes 10 seconds for the phone to recognise the charger after is is plugged in and that is consistent each time I plug it in. The phone now isn't recognised by my PC via USB, and also won't charge that way also, it just doesn't do anything if I plug it in there. Other than that, the phone works and it holds its charge well.
Any ideas? Thank you.

pick up an original sony charging cable - no idea why it makes such a difference, but.........
Hi, thanks for the reply, I bought a sony charger but it's still the same, drawing about 50-300 milliamps from wall charger, not recognised by PC and takes 10 secs exactly for the phone to recognise it's being charged. It's just odd how it stopped charging before the "fix", now the new flex lets it charge slowly. Can a battery problem cause this? It still holds its charge well. Maybe this problem is recognisable by some phone repair experts around here? any ideas?
Thanks
Noticed the phone only draws charge from a 3amp charger, anything less isn't recognized. And the power drawn from a 3amp can be 30-1000ma but averages around 300 ma. Can anybody point me to a hardware forum maybe? I can't find any, i guess it need taking to a phone expert but it's gonna end up costing more than its worth with the stuff i have done already.
Aukey Quickcharge 3.0 is working fine. It is cheap too.
I have just purchased a aukey charger, but my XZ seems to be taking longer to charge than the UH20 charger that came with my XZ. Any suggestions guys?

Have you tried cleaning/replacing the charging port itself? As i see, you replaced only the flex cable.
There's probably extremely weak contact somewhere in the charging hardware i think, because you need 3.0 A charger to get any kind of charging response. Weaker current probably gets lost at that 'weak contact'.
Buying new chargers won't fix that if you ask me
I have exactly same problem with you
I am about to buy a new charger, yet I saw your post
At first I thought it was the cable. Then my cable work normal with other phone. So does my charger, it connect perfectly with other phone (xperia xz premium and xiaomi mi5)
It seems that our phoneis the only one who can'y charge normally.
I am quite depressed, also looking for solution. Mind if you share if you have succedeed? Thanks before

Try plug in and plug out. My phone sometimes charge a normaxl. But need a lot of effort
Solved
Use the the detect usb in the notification keys before connecting the charger,, this will solve the fast recharging issues
Did you solved problem? I have same issue. Changed battery, usb-flex, no luck
Hi,
I have bought an used XZ.
The owner sold me this phone because he need new battery. I have replaced the old one after a week of test. The old battery works only for 6/10h and drain totally during night even if the phone is turned off. The new one have the same problem. I try to solve with an other battery, and nothing same problem. 12h of standby, after is totally drained. The strange thing is that I have the same battery life even when the phone is turned off, but not only this. If the phone is in 0% he charge without problem. If we have any % of battery I need to connect and disconnect the charger from a wall plug many and many times before he start charging. Phone give me the charge icon for a second and after nothing until I disconnect the charger from a wall plug(I have tested different charger and cable). During my investigation I have found that this phone results every time a little bit hot even if turned off. I have try to disconnect all is possibile, but the heat is from CPU! Now I know that this is the cause of fast discharging in all conditions.
Now I need to know if anyone with a "normal" unit feel the phone heat while turned off and while is on wich temperature have. Mine is every time on 34/35° in standby. Let me know,
thanks
i have same problem . sony xperia xz and sony corp is very very Rubbish
Hi Guys,
I found a way to charge my Xperia XZ with the same loop problem.
Try to push upper volume pad together with power button and plug in the charging cable.
Hold the buttons for 3-5 minutes - you will feel vibrating signals like 3 short and 1 long.
so hold it and then simply leave it for a several minutes and it should start to accept the charge.
Alex Kutikhin
Yes - I had this problem...fixed it by holding in POWER UP and OFF button for 120 seconds.
Do not let go...you will feel vibration (1 short, 3 short). Keep holding for 120 seconds.
Device should now be powered down. Plug in charger cable and leave device off until 100% charged.
Still no fix for the original post’s problem? Having the exact issue with my xzs right now.

Old Thread, I know, but I encountered this issue today on an Sony X compact - F5321. Fixed it and want to report back for the next guy.
Same symptoms, noticed first a slow charge, phone was drawing low current and only responding to cable after 10 seconds of plugging in. I than checked for data connection, couldn’t get any. Opened it changed the USB port - BINGO - that fixed the issue, everything working nice.
TLTR: no Solution in Software, it’s a faulty USB-port. change it.
Have a nice day.

slow charging

My s8 is slow charging and says to use the original charger and cable but I am using the original. Anyone else having this issue?
never-mind...started working after a reboot.
same issue
my s8 take up to 3 hr to full charge :crying::crying::crying:

It should not take more than 2 hours. If it is saying slow them you've not connected the cables firmly into their ports. If you have, you have a defective phone or cord.
I doubt this is the issue but I just noticed that there is an option (settings -> battery -> advanced settings) to toggle "fast cable charging" on or off.
I think it is enabled by default but might be worth a look.
Have the same problem. Went to settings > battery > advanced settings... Unplugged my cable, turned off fast charging, plugged the cable in, unplugged it, turned on fast charging, plugged the cable in and it works now.
Slow Charging and Charging gets stuck
I have S8+ with me from last 10 days. Charging with original charger takes a very long time. Horrible. Moreover on reaching 80%, the charging stops even though charging emblem is active. I have to plug out the cable and re-insert and switch it on afresh, then it starts charging, of course slowly. A strange behaviour.

I am having exactly same problem. Also it has increased in past 2 days. Now it stops at 73% too sometimes. Also when my wireless charger came 3 days ago, it was unable to charge more than 3% in 20 minutes, and just stopped after that for more than 1.5 hours. I even took of s8+ from wireless charger dock and put in on again, but not charging after that.
The dealer i bought it from checked it infront of me, and it was charging properly upto 100 in his shop. But i checked it at my house and my shop, even at my friends home and its the same issue.
Right now trying to get a replacement. Dealer says that i have to talk to samsung through voiceover call, and fight them to get replacement or i wont get it. At the time of purchasing, he said he will do everything to get replacement if any issue comes up. Now says can only get replacement for first week, any longer than that and cant get it.
I paid 64,900rs for it and cant get replacement for a faulty phone within 15days. SAMSUNG SUCKS. Next time i will go for oneplus or xiaomi, cuz i may not get replacement there either but i will lose a lot less money.
you guys have something wrong, my S8+ charges 0-100% in about 1hour 45min.....and this is the normal charge speed, try another samsung original cable, maybe the cable head or the S8 port is damaged
No its a software problem that Samsung needs to fix because it not just 2 but a lot of people

Don't use your phone while charging ...
But should go into slow charging when in use. Should at least have a message saying that or a message saying charging when you use it instead of fast charging

Is your phone overheating while charging ?
What's the ambient temperature in your location ?
There is something called swelling prevention mode where the phone stops charging when the battery temperature reaches a certain point..

I dont use my phone while charging. Also if i use it while charging it, it mostly doest even charges. Just remains at same percentage when i put it to charge.
It doesnt heat up. Remains pretty normal. Even if i play a game like mc5 while charging it at the same time it doesnt go up much in temperature.
I put my S8+ on the charger with 20% and the wife's Nexus 6 with 35% at the same time. Both are supposedly fast charge and the S8+ was at 100% 30 minutes before the Nexus 6. The S8+ has a 3500 battery and the Nexus 6 has a 3200 battery, I wouldn't call it slow charging.
I have the same problem. I can't remember if it started charging normally after unplugging the charger itself and then plugging it back in or after restarting the phone. One of those fixes it. Hoping for a fix from Samsung/Android soon!
Really odd. A reboot didn't fix the same issue for me. What fixed it was turning the charger around. I'm talking about the bit that goes into the phone. I was under the impression that with usb c it didn't matter which way the charger went into the phone. I've tried this several times and get the same result each time. Slow charge when plugged in one way and fast charge when charger plugged in upside down if that makes sense. Could I have a faulty charging cable? Or a faulty phone perhaps?

“This is a normal operating condition to prevent damage to the device.”
: While charging the S8/S8+, sometimes charging is stopped even when device is
not charged fully.
because
: During wireless or wired charging, the device and the charger may become hot.
For your safety, Samsung has applied charging algorithm to protect device
overheating.
If the device heats up or the ambient air temperature rises, the charging speed may
decrease or stop automatically.
In Samsung authorized wireless charger, cooling mechanism (such as cooling fan,
air hole…) is applied.
Wait for the device to cool down and then begin charging the device again.

Help with charging

Recently, my got hit by the floor i the back, and at this point every time i connected it to the charger it wouldn't charge saying it's cold.
I tried replace the wireless module, the battery and even the charging port module.
I also formatted the phone but nothing seems to be helping.
If anyone here has a solution for me, i would love to hear it.

Sounds like a hardware related issue.
Does charging via USB cable work? Or via wireless charging?
The phone says that it's too cold to charge? If it is not that cold, maybe the temperature sensor is defect preventing the phone from charging the battery

High g impacts can damage chipsets, crack solder joints and... thermistors. May be just a loose connector but it needs to come apart to be repaired.
Get the battery replaced while it's being repaired.
