[Q] Battery suddenly charged extremely slowly

So up until now my battery has been charging really quickly, with ~1 hour to charge to full. Just last night, however, it suddenly started charging exceptionally slowly. Left it plugged into the Samsung wall charger at 41% and when I wake up 6 hours later it's only at 92%. I had noticed it charging slowly late yesterday as well.
I don't think the problem is with my ROM or any apps I'm running, because I get the same unsatisfactory results whether the phone is on or off before I plug it in.
The only thing I can think of is this: yesterday, when going to plug in the wall charger, I accidently plugged it in such that only one 'pin' was pushed into the slots (specifically, the left-hand slot). It was like that for about a minute before I realized I goofed. Could it be that that somehow messed up the battery/cable/charging mechanism? I've already tested against two different wall chargers, so that isn't the problem, but I haven't removed anything else.
Anybody have any idea what's going on, and possibly how to fix it? I'd rather not have to unroot and go to AT&T, but if I have to...

Original SONY DK31 charging dock issues.

I purchased an original charging dock and I've noticed some strange issues. There are times when it just seems to disconnect itself randomly. It will charge the phone for a few seconds, then disconnect for a second, then charge for another few seconds and so forth and so on.
There was one time when I placed my phone in the dock before going to sleep, I think the phone had somewhere around 20% battery left and by morning, my phone was completely discharged and it didn't even power on until I charged it by cable for about an hour.
Strangest thing is, it seems to only do this when battery is low. I've tried using it when battery is over 80% and it doesn't seem to show this issue anymore.
Does this make any sense? Should I return it?

I would probably say that the magnetic cable is not connected properly but... If possible, try charging it again, say for a period of time - 10 mins perhaps etc or checked with your friends/family and use their phones to test it out too.
Personally, I never like the dock as similar issues that has happened to you, happen unto me too!
My solution to this - took out the cable straight out of the docking mechanism (do this at your own risk - as it will void either the warranty or refund)
Perhaps this link may gives more information -

I did exactly that. Took out the cable and now it seems to charge ok.

That's great. I had a bigger problem, but not with the dock. My device was not charging(it was discharing) and the phone kept spamming the charge sound. I opened it up and i was suprised that my phone was already opened(bought it 2nd hand) and the dock connector was detached(only the back door pushing it a bit.). I connected it and everything works perfectly now. I am glad that you solved your problem easier.

HI,
had a similar Problem with this docking station. For me it seems that the docking station doesn't fits right to the Smartphone. I put a plastic card (like a credit card, but without any chips) behind the Phone when i charge my phone with the docking station.

Problems charging watch when switched off - overheating

Hi!
I bought my Sony Smartwatch 3 about two months ago. I've always updated the watch and now I'm on the latest build MWD49B.
I don't know precisely when the problem started, but for sure also before updating to the latest build it already showed it.
Basically if the watch is turned off it won't charge and it'll overheat a lot. I mean it maybe charges at an absurd rate, like from 60% to 100% in about 4 hours.
I tried changing charger (1A and 2A) and charging cable, but it doesn't change. It's like stuck in some way. The funny thing is that when it is stuck in this state if I turn it on (with the same chargers and cables) it starts charging fast (normal charging times) and funny enough it gets colder than when it's turned off charging (I mean slightly hot but colder than when it's stuck).
Do any of you has this problem?
Could it be a SW problem too or just HW? I haven't tried to reset it yet, but would rather lose time in resetting it and reinstalling all my stuff than losing time in the RMA process and waiting time to have it repaired, even because thinking of running without it makes me feel already mad!

I also have MWD49B and I'm charging my watch with (AFAIK) a charger which was bundled with Xperia PLAY docking station. Its output is around 500mA. Sometimes I was charging the watch with EP880 charger (output 1,5A) and I was charging it with BlitzWolf charger (output 2,4A). I've never had any problems with overheating and I pretty much never turn off my watch even when charging.
The problem is that some watches (especially the fresh ones from 2014 with glossy grey cap on microUSB port, not the full rubber ones like my watch have) might have faulty battery. If it overheats, charges 4 freaking hours... well it's REALLY long... my 500mA charger charges my watch up to one hour and I have no problems at all...
If you still have warranty, I'd suggest returning the watch, this overheating might be dangerous.

Hi!
Thanks for the answer.
My watch is from an April 2016 batch (written on the box), and it's one of those with the rubber cover on the charging port.
Just to be clear, if I charge the watch when it's ON, I don't have any problem and it is charged in less than one hour, the overheating problem and non-functional charging is present only when the watch is switched off and it is charging.

Me too...
I bought my Sony Smartwatch 3 about one years ago...
Whan I first charge it from PC's USB port , the same problem with you..
I don't know why...even I reset watch , it's the same...
So..I always charge the watch when it's ON...

I have the same, "new" batch, with rubber cover on USB port.
I'm not sure if I missed some of your text from the original post or you edited it. I'm talking about switching the watch on so it does not overheat.
I've noticed my watch behaves exactly the same! If it's turned off and charging - it's hot like hell and not even fully charged after two hours and if turned on and charging - cold and fully charged after like... one hour.
Strange because on earlier Android Wear builds everything was ok.

Same over here.
But I didn't try charging it while it is running.
But when it's off, it only charges up to 75% and gets insanely hot. Then, when used it drains normally until around 50%. After that, the battery dies within 1-2h
I also never had any issue with the battery before the last update.

I've had this exact problem. One thing I discovered is the battery will stop charging when it reaches a certain temperature. Try placing a fan to blow directly on it while it's charging. This has worked for me.

Same problem here.
I've got the SW3 of 2015 vintage (it does have a cover over USB - I thought they all did?)
Since updating, if watch is off while charging it gets very hot, charges very slowly and never to 100%.
The solution is simple enough - charge it while OS is running.
If the watch is out of juice: Start charging, let it get enough to boot and then again allow it to complete charging with Android Wear running. Then charges normally (about an hour) and doesn't get hot.
My feeling is this is a software issue too. I'm running M1D63G.
Since we all know batteries don't appreciate getting cooked, I'm wary of leaving it charging for long when off, I'm betting it will cause battery damage eventually.
Conspiracy theorist's might even suggest it's Sony's way of ensuring our SW3 batteries die, so we're ready to update to the SW4 - I'm not that cynical.

Hello everyone, here's the matter don't know where to ask it so this thread is similar...
I have 2 Sony3 watches, one with screen partially broken and the second I got it secondhand with a charging base made by the previous owner.
The watch that came with the charge base it always has the charge icon on screen even if it's not charging, sometimes if i reboot it dissapears but most of times it STAY :/
if i turn off watch vibrates and start "charging" all alone without connecting it so i don't know what to do with that cause it obv drains battery and its never really off...
Second thing, my old watch with broken screen worked well since i plug it into that base.... then is doing the same as the other watch, charging forever without charger seems like the base charge illness has affected my old watch too... XD
So pleaaase anybody know something about this? i've restarted them several times and with pcCompanion and the icon remains maybe a custom rom will solve or is hardware issue?

I am using may sony smart watch 3 for long time and i kept it for some month after then i carry it and begin to charge it but it will only show sony and then will not proceed i kept it again after i carry it i plug the charger and it only vibrate

This watch needs to be recalled or have an emergency firmware update. My smartwatch 3 overheated while plugged in overnight and melted apart. Thankfully it was on a metal computer case and not some paperwork. This annoyance has become a real safety issue. It's a shame because I loved this watch otherwise.

Just a general FYI to all of you, use a USB Port or a charger that charges slow and always turn it on when you charge it.
Our watch is really different compared to anything nowadays. It shouldn't but still charges faster than it (should) be allowed.
My Watch is still with it's first Battery and it holds for at least a day, just be careful

Pixel 2 XL stopped fast charging

My device has recently stopped quick charging. Instead it's charging but an absolutely slow rate. I've read that the device temperature can cause this but even after having it warm by playing videos it doesn't rapid charge...
It's stating that it's charging rapidly but the estimated full charge is about 5 minutes for every minute it's actually stating.
I've factory reset the device to no avail, changed cables and charging plugs.
Honestly, this is putting me off buying another pixel device - my Pixel 1 XL suffered with screen burn. I'm just tired of the device breaking after having it since July 2018.
Does anyone have any advice before I start the ball rolling with the warranty?

Clean the USB port on the phone

I agree cleaning the USB port might help.
I had a charge rand Phone overheating issue and it was that some water was in the port.
Even dust has metal particulates, so cleaning it and making sure no dust or water is in, is a great idea.

Cleaning the port worked for me few weeks ago,i had to try a few times with a toothpick

So I've cleaned the charging port. The device when screen is off is coming back charging at 850mah when I plug it in with the screen on it charges at 1000mah.
Can someone send me over what there's charges at after having the phone screen off after half an hour?
I think there's something wrong with the battery, just doesn't feel like it's charging like it used to.

This is what the ampere is showing when I've plugged in the device.

To put this in perspective.
Here's my old Nexus 6P.
Can someone show me what their Ampere shows when the device has just been plugged in and then what it's like when it's been on charge for a while?
That way I can have an understanding as to what a Pixel 2 XL should be charging at.

Weirdly the device seems to be charging okay today. I'm gonna see how it goes, probably warranty if it happens again.

First, that app isn't the most accurate way to measure charging.
Second, fast charging is at it's fastest when the battery capacity is low. So below 20% you'll get the highest number. Your screenshots are 73% and higher.
So typically for me, I gain 70-75% in 60 minutes when I start at 5-10% and don't interrupt it with use. It's been like that since I've gotten the phone October 2017.

Some screenshots showing this morning's charge. By the way, going from 80% to 90% is slow, and 90% to 100% is very slow. That's why when I'm topping off, I just unplug at 1 hour or around 80% because it's a waste of time to wait any longer.

Okay, so I've just let my phone charge whilst off as it was drained completely. It was the full length of a breaking bad episode (rewatching).
Pick up the phone its very cold to touch, I then turn the phone on, it's at 20%.
A device for 40 minutes doesn't go from 0-20% when it's using a fast charger... I should be on at least 50% maybe even 75%

Very strange. Stock charger right? Don't think it would matter but I've never charged with the phone off. I would try to replicate what I showed you in screenshots. 15% plug it in, phone on but screen off, set a timer for 1 hour, return and see where you're at.

I'm experiencing exactly the same problem l.
My pixel 2 XL stopped charging at all of the sudden and only accepts slow charging and with a "Chinese" cable. The original cable doesn't work. No the cable ain't broken or the charger. My girlfriend has a pixel 3 and she uses my charger and cable and works on hers. We used also her charger and cable ( from pixel 3s ) and on her pixel 3 everything works comes to mine it doesn't even recognize to start charging.

Last night I drained again, charged with another stock charger I have, completely different house - was at my partners house. Again 35 minutes, switched off, 13%.
I'm going to have to call my insurance company, I get insurance with my bank - I'll have to pay an excess but they should be able to sort it I think.

This what you're experiencing sounds different to my issue.
My device fast chargers when it's plugged in. I have read that the Pixel 2 XL charges at a massively slower rate if the battery is at 20 degrees or below - this is unacceptable as the phone switched on, the battery till be always below that.
What's frustrating is the tips and support options in settings doesn't even open anymore, whether they've killed that feature off or not...

General Pixel Stand 2 stops charging

This started happening a couple of weeks ago, prior to the latest update.
When I put my P6P on the Stand 2 at the end of the day, I get the little sound and animation that it started charging. After a few seconds I see the message at the bottom that it's "charging wirelessly" and a time until full. I have the stand set on Max Charging and adaptive charging turned off. After a minute or two, the fan comes on. About 10-15 minutes later, it stops charging, (the message goes away and the current % is shown), and the phone is really hot. No matter how long I leave it, even overnight, it never starts charging again. The phone remains really hot until I remove it from the stand.
About 50% of the time, if I reboot it, it will behave normally again, but last night nothing I did would get it to charge wirelessly. I ended up plugging it into the wire. It never gets warm when charging on the wire.
It has been working fine since I purchased it in Nov. This just started a few weeks ago. Has anyone else seen this?
Dave

Try cable charging.
Charging will disengage if the battery temperature gets too hot, about >103F
Fast charging may disengage if the temperature gets beyond 95-100F.
Ideal charging battery start temp is 82F.
Erratic charging can indicate a failed battery.
Any swelling is a failure, replace asap if so.

As indicated in my OP, cable charging works fine every time. The phone doesn't even get warm. It's only wireless charging that's an issue, and not every time I try to charge it wirelesly. It's like the phone decides to stop accepting the power, and it starts to heat up because of it.

I take it you don't have a second wireless stand to rule out if it's the phone or your STand 2 that's behaving badly?
I have been using a genric set-up from charger to stand with my P6P and did have charging issues a few months ago with wireless charging not working correctly but the May update fixed it.

May be a hardware failure in the phone or stand.
Remove a case if it has one and try.
C ports generally last for thousands of charge cycles and cable charging is better for the battery, produces less heat.

No, unfortunately I only have one stand. I'll keep trying things to see if I can narrow down the exact situation when it occurs. I was mainly checking to see if anyone else had something similar happen and there was a quick fix.

Yeah, and I've always used cable charging on all my phones in the past with no issues. I thought the stand was cool in that it could fast charge and keep the phone upright so it's easy to read in the middle of the night. I'd really like to keep using it. It was stupid expensive and I'd hate to let it go unused for that price.
Thanks!

I've been experiencing similar problems with my Stand. Sometimes it charges normally, sometimes it charges REALLY, and I mean really slow... And sometimes I get the "Not charging" message for whatever reason.
I think it's gotta be an issue with the adaptive charging on the Pixel 6 Pro, because every time I put my other phone on the stand, my S21U, it charges without any issues.

Yeah, I feel you. It could be firmware, a SEU which are rare but do happen. A reflash would fix it if so. Probably not worth the trouble to try and more likely to be hardware.
Cable charging be the best plan for now I think.
The old micro connectors were horrible and invariably would fail. The C connectors are much more robust. This N10+ is heavily used and the C port jack is still tight and has well over a thousand cycles plus a few drops and pulls. Even the original cable is still AOK.

Just came across this thread while looking for similar problems on my P4 with a 1st Gen stand. The phone showed the normal 'xx% charging wirelessly' display then at 79% it changed to simply '79%'. After a while the message went back to 'xx%charging wirelessly'. I took the phone off the charger and using a utility app called 'inware' I looked at the battery temp which was at 41.5C/106F.
So I'm guessing that the phone will stop charging when the battery gets hot and resume when it cools down a bit. What is 'too hot' and when does it cause damage, I have no idea. Google told me in a chat session the other day that it's perfectly acceptable to leave the phone on the stand all day. Personally, I take it off at about 80% charge which lasts me all day.

Mine also has this behaviour, taking it off and placing it back on continues to charge

I just sent my stand back for similar reasons - not good when a $12 Qi charger from Amazon was doing a better (and faster!) job charging.

I sent mine back too & am now using a charger that I bought at IKEA for £5. It's a shame as I thought that Google would have made more effort to integrate the charger & phone. Oh well, bling gone!
