Not charging

Last night my phone died after 2 days off cable due to me having to use my cord for another device. I plugged it in today to find that it wasn't charging at all. I decided to give it a few minutes before trying, thinking it may not be turning on because it still needs some juice. I waited 30 minutes and it wouldn't turn on still, just gave me the little animation of a battery draining to indicate that it needs to be charged. After this, I figured that it's possible the cable is just dead, so I opted to borrow a cable from my brother. The cable charges his phone just fine, but it doesn't work with charging my phone. I took a shower while waiting for it to perhaps get the juice it needed, and still no dice. I tried several different outlets thinking perhaps the outlet was dead, and still nothing.
I've had the phone for a little over a month, so I'm not sure how long I have to turn it in or not; I'd hope it'd be 3 months for factory issues, but judging from how people mention 14 days, I'd assume that they're eager to push responsibility of broken devices onto the customer as fast as they can. Do you guys have any idea of what could be wrong? Perhaps if it's possible for me to get a replacement at this point?
I've been running the Lifeless v.11 Rom for a while with no issues, I haven't flashed anything in possibly a week or two, so I honestly doubt this is a software issue. It's never been exposed to water, but then again I really don't trust phones to detect if they've been damaged or not since it seems even a humid day is enough for those small water damage detection stickers to run pink.

Pull your battery, try again
Sent from my LG-LS970 using xda app-developers app

Yea, going to update this. Sprint was giving me issues and trying to cough up money from me, so I pulled the battery and cleaned the port with a q-tip and it charged fine again. I was in for a scare there, but it's back to life.

Same problem...didn't have to pull battery

Just wanted to chime in with my experience.
I had same issue. Battery completely drained with a visit to the relatives (low cell signal).
Got home and plugged it in for 5min, the "battery charging" animation came on when short pressing the power button.
Had to move the phone to a different charger for the night and noticed that I couldn't get it to even show the charging animation while on the charger. Indeed after 8 hours on the charger the next morning it still wouldn't turn on. I thought I would have to take it back to Best Buy. On a whim, I thought I would drain all of the capacitance from the system by pressing and holding the power button to see if that would allow it to restart the charge cycle. So I held the power button for about 30-45sec off the charger, then waited about 30min and plugged it in at work.
It worked. Not sure why, but I didn't have to return it to Best Buy, so I'm happy.

[Q] DOA

Watch has set on the charger for about 4 hours now, and I haven't had a vibrate or screen turn on at all. The charger light on the charging unit turns on, but nothing from the watch at all. Anyone have any suggestions? I'm about to call moto and get it sorted through a probable replacement. Sort of annoyed that the QC is this bad.

Just a couple of quick questions:
(1) I know you said DOA, but I just wanted to clarify that is has never worked, or worked for a little while, then didn't work?
(2) When mine arrived, it had 37% charge and for some reason it didn't charge the first time I plugged the charger in. The light came on, but it wouldn't charge. Strangely enough, I unplugged it from the wall and plugged it back in and then it started charging. I'm not sure why, but just in case you haven't tried that yet, I would try that. I may even have used a different plug.

Make sure it is fully seated in the charger. Is there any warmth on the back of the watch when you remove it from the charger?

There is. With the stock charger, it is warm to the touch and the feeling fades with time off the charger.

As in DOA, meaning I took it out of the box and attempted to power it on with no vibration, screen lighting or any other form of feedback to indicate it was on. I have tried it with both the stock charger and a charger I use with my M8 that has a higher amp output.

Mine was the same way, totally dead out of the box. But after sitting in the charger for 20 minutes it finally turned itself on and so far seems fine. Maybe yours was just too dead to recover from.

I actually thought mine was DOA as well. Even left it charging overnight with no signs of life. It turns out that I was not pressing the power button hard enough. Once I REALLY pressed the button in for 3+ seconds, it powered right up! Haven't had that issue since then, and the power button now seems to register normal presses just fine.

I just tried this as well, and had no luck. I think I will call Moto tonight and get this resolved once and for all.

On the one I bought this morning I thought it was DOA until I peeled the plastic circle off the back and placed it on the charger. Did you take the plastic off?

That I did. Called Motorola support and they will be sending me a new one. Will see if the condition changes before the new one gets here though. It's still sitting on the charger and still getting warm to the touch.

Just to give some final closure for anyone in the future, I recieved the replacement today, and it works just as intended. I think the issue with my other one was that the power switch itself was faulty, as this watch has a much more noticeable firm 'click' when I press it (The other one just sort of softly clicked.) Replacement was sent overnight, and arrived working out of the box. With that said, and after customer service messing up not just the email address, but also my name, I would say that Motorola's support is quite shoddy at best. I just hope they actually reverse the charge on my account for the replacement watch.

I just want to add to this thread, this is exactly the issue I'm seeing with my brand new Moto 360. Just purchased from Best Buy. Took it out of the box, held the power button (as the instructions say) and nothing. I plugged the charger in, unplugged, replugged, etc, no dice. The light on the charger lights up and the watch gets warm. I've let it charge for over an hour, and still have yet to see anything on the screen. The button "clicks" when I press it as opposed to the OP's issue. I guess I'll just take it back and exchange it, just hope this is not the norm with this device.

Pixel C bricked after first charge

Purchased as a Christmas gift a couple of weeks ago and worked great out of the box. It was put on the charger at the end of the day to charge. Next day come back to the tablet only to find it will not power on.
Tablet gives no indication that is plugged into the original charger. Pressing and holding the power and volume up to try and access the bootloader provided no response.
Calling this one bricked unless anyone else has thoughts or suggestions. Have seen this with other Android devices in the past but where going on 3 years old. This guy is only a couple weeks old. 1 day powered on even.

Can you try a different charger? How much battery was left when you put it on the charger?

Couldn't say what the battery percentage was at, it wasn't dead though. I was given the tablet back to try and troubleshoot and only have as much info as I was given.
As for the charger, this is my one and only USB Type C device and only have the original charger it came with. I was told however that a type c cable was used from a laptop to see if anything worked. No response I am told.
Have a few days to wait until I can RMA it. I will see if I can source another power adapter.

there are many [upwards of 20 or so] reports that it takes between 15 and 20 seconds of holding power button down to power up the device. i have had it happen twice. the largest thread for this issue i have read is on reddit.

I've had it happened to me twice on my first unit and twice on my RMA'd one now. Every time it happened it was after leaving the tablet unattended for several (12+) hours, regardless of battery % (anywhere between 10 and 60%). I never turn it off to make sure I don't get the touchscreen issues again as these come back everytime I reboot the tablet but when this happens there isin't much I can do as it turns off by itself. I can confirm that a very long push of the power button (agree with the 15-20 seconds mentionned above) also does the trick for me. Same pattern on my first unit and my 2nd one.
I'm realllllly hoping Google will have a software fix for all of this (touchscreen issues, awful Wi-Fi download speeds/range on 2.4 Ghz and this (tablet going dead without any apparent reason and being hard to reboot)) as I want to love the tablet but it's a mess right now.

Thanks for the reports.
I held down the power button till my finger went numb. Still don't know if the tablet has a charge and if the charger even works.
Same thing happened with my GPe htc one. Charged, freaked out, rebooted and then bricked never to come back to life.
Would have been nice to have found reports of issues before. Every search brings up reviews however. Hopefully this thread gets indexed.

Don't know if this is related: I've had the tablet for about two weeks and have twice had it not turn on (or respond at all) when I pressed the power button (short press, long press--although possibly not >15s). Even though I thought there was well over 50% battery left and even though though tapping under the cute LEDs showed four greens, I plugged it in and just left it for hours. Then when I came back, everything was fine--it turned on immediately.

I know this is old thread, but though this might help someone: my pixel c won't charge unless I
1) with the device plugged in
2) hold power-vol up-vol dn all at the same time
3) un plug the cable
Can be hard to do with only two hands. "Charging" will pop up on the screen immediately for just a second when you pull the cable if you did it right. I often need to do it more than once. Thanks Google!

My Pixel 3 XL died suddenly

Yesterday morning My Pixel 3 XL suddenly died while in a call. It would not restart.
My day had just started, Pixel 3 XL 128gb fully charged over night, was in a call for about 20 minutes while going down the highway. The phone was in the wireless charger. All of a sudden My Bluetooth switched back to radio I looked down The phone was dead, my call was dropped.
I had about 45 minutes more to travel so while going down the road I attempted to restart; holding power button, holding power and volume down. The phone was not hot, after a while I plugged directly into my rapid charger. The phone wouldn't show any indication of life. No vibration, charge indicator, nothing. Left it on the rapid charger the remainder of the trip.
I let it sit on/off the charger, switched to factory charger. Several hours later attempted to hook to computer, no drivers loaded, no fast boot, no ADB...
Contacted Google, and went through all the troubleshooting steps again. The Google CSR got a replacement on it's way, no hassles. It will arrive in about 2 days.
I'm persistent, and continued troubleshooting last night after is sat for about 4 hours. Finally, I put the phone in it's box, it sat there for about 24 hours.
Tonight I pulled it out and pushed the power button and it started right up normally! Battery was at 23%, so Something must have hung for the entire day. I looked at the phone log and the 20 minute call was missing, the call prior to that was logged.
I Pulled all my precious photos, docs, and pulled out a logcat. Nothing was logged from yesterday. Gonna wipe it, and send it back with a note.
Edit:
About to go to bed, put Pixel3xl in google charger stand, it went black and restarted, now it bootlooped a few times, starts with clock at 12:00, get's NTP and changes to correct time. Gonna try to get some logcats again.
My failure was triggered by attaching the charger; Google Stand and google usb c charger now causing reboot, and bootloops until removed from charger.

Yup,
It was in a wireless charger cradle.
It's a hardware problem, just reset to default and its bootlooping while plugged in. Runs for a few minutes with charger unplugged. I got all my stuffs out of it, and it's wiped, so it's going back to google.

Gotcha. I was having this image of a Pixel stand sitting on the passenger seat with power coming from an auto>AC adapter. LOL! Seriously though, it does seem coincidental that while numerous complaints are showing up about the Pixel 3 series having issues running apps while charging (especially wireless charging) this happens to you while using a 3rd party wireless charger. I know you said it wasn't hot and you are getting a replacement. I just fear that your issue might repeat itself under the same usage pattern.

What type/model wireless charging cradle?

I'm curious. You said your day was just starting and it was fully charged. Why on earth is it in a charging cradle if it's already fully charged? Just wondering because I have yet to run he battery down to zero unless I don't charge overnight and try and stretch out my screen times. I have been getting over 7 hours SOT along with music playback while I commute. That on top of phone and text.

FWIW I exchanged a Pixel 2 XL about 2 months ago because it was having odd/random reboots. I had purchased a P2XL from Google on launch, ended up replacing it through VZW insurance after the screen cracked (didn't have the Pixel protection). Had that one for about 3 months and I would often take it out of my pocket to a freshly rebooted phone, or it would reboot as I removed it from my pocket.
Was annoyed and started removing apps thinking that was the issue. One day I was in a meeting at work and mindlessly spinning my phone on the table while and it rebooted. Spun it again and it eventually rebooted again. There was a mild click/rattle when I shook it that I had attributed to the OIS but every time I shook it, especially when inverted (charging port facing up). I contacted the insurance company and they sent a replacement. A few weeks later my P3XL arrived and I sent the P2XL in as a trade. I can only assume something was loose inside the device. Could be the same with yours. Glad they got it replaced for you.

It was in an iOttie Qi Cradle/wireless charger. I found out after purchasing several of these chargers that the Qi standard won't fast charge Pixel3's. They charge at a about .5 amps.

This device has rebooted several times over night. In fact That fateful morning when I turned off the alarm it had obviously rebooted since I had to enter the pin, and finger print.

This same thing happened to me today. I dont know if mine is going to start working again, but I did get a replacement ordered from Google. There is a common factor between yours and mine, I too was using an iOttie Qi Cradle. Looks like that might be a problem. Im wondering if I should continue to use it or not. Are you going to still use yours?

What Google number did you call for help? Yup, Mine died watching Youtube while using a Samsung wireless charger. I have the Pixel Stand just not one in every room.

MIne just died as well. Was sitting in a Samsung wireless charger also. Wtf people?

Mine also died today but I was using the Pixel Stand, replacement is on its way. I did manage to turn it back on after about an hour and a half of holding the power button down. The phone allows me to use it for about 30 seconds before it boot loops and if I plug a charger back into it or place it on the Pixel Stand it will go back in to the dead state.

This can't be good! Too many reports here with same issue. Does Google know what's going on?

I had exactly same issue. I've been using an iOytie wireless charger. Mine just shut down. So I powered up and in 30 secs, it would shut down again. Eventually it wouldn't even power up, so I RMA'd it.
New one seems ok...so far!!
On my fourth pixel 3 XL now!

Is there any support for multi-window mode?

Not if it dies suddenly.

I had my phone crash once too while in my car wireless charger. It has not happened again in over 2 weeks.

FYI - this isn't just a cradle issue. I actually had this problem on my FIRST 3 XL, and managed to get Verizon to exchange it in store a few weeks ago (got it on Black Friday for a great price, though the forced monthly payments to retain the deal are obnoxious). Full charge, and just stopped working. Actually got it going after a half hour, but only as far as the hard reset key function - and it froze halfway through the reset. That's when I went to Verizon and had some words.
So, here we are, new one... THIS hasn't happened yet, but I've now had three instances where it wouldn't charge. I bought the cradle, and avoided that intermittent issue - but now it often thinks it's connected to USB when I de-cradle it, and I've had several repeats of the "won't charge" event. This occurs on both OEM and non-OEM chargers, and I found that rebooting the phone fixes the problem. That to me screams OS or drivers.
Anyone heard any news on their problem? (FWIW - I left an OG Pixel XL for this... and have had more problems with this in the first three months than I did with the OG in two years, running beta releases.)

HELP! Can't charge Galaxy Tab S 10.5

I've been having all kinds of trouble getting my tablet to charge. It's acting really weird. Over the last couple of days, I will turn the tablet on and it will say 80% charged (after being plugged in all night). Then, with it still plugged in, it will drain down to 15% in about 30 minutes. Why would it drain so fast (if at all?) when it's plugged in? It's also been taking hours for it to charge once it hits that 15% and I don't use it.
At first, I discovered my charging cable was to blame. I'd plug it in, but the tablet wouldn't detect it was connected unless I pulled on the wires just right for them to make contact. Apparently there was a broken wire inside the plug of the cable. So I replaced it with a new cable. Everything seemed to be working good then, and was actually getting proper charges again. Now though, it doesn't seem to want to work.
I was using the tablet yesterday to check my email. It had been plugged in all day and not being used. It said it was at 100%. After about 10 minutes though, the tablet shut off saying "battery low". When I try to turn it back on, I get the battery indicator showing it's at 0%. So I left it plugged in the rest of the day and over night. I just went to turn it on about an hour ago, and it's still sitting at 0%!
I thought maybe the cable was bad again, so I found another charger and tried that. It does the same thing the other cable does.. It stays off until I plug in the cable. Then, as soon as it's in, the tablet "wakes up" and displays the battery indicator. Like, it detects a power source has been plugged in. But no matter what I do, and how long I keep it plugged in, it stays at 0%. I can force the tablet to turn on by holding the power button. It goes through the boot animation prior to loading the screen. Then, in about 5 seconds, it turns itself off again.
I don't think the battery is truly at 0%. If it were, how would it be able to boot up without even a cable plugged in? I really don't know what to do now. I've rooted it, so I can't send it in to Samsung for repair. I don't even think the warranty would still be good at this point anyway. The tablet is at least 3 years old (based on when I joined this site looking for root help). And I think it was 2-3 years older than that before I bought it. Is there anything I can do?

I can't wait anymore. So frustrating to own something that's worked great then all of a sudden decide to no want to even power on anymore. I've spent all day trying to get it to charge with other cables. I've tried chargers, I've tried just straight cables. Plugging into the wall, plugging into the computer, plugging into the USB port in the car. Nothing works. So I hopped over to Amazon to just order a new tablet. I can afford it, not big deal there. But then I saw a ribbon cable used to replace the USB port on the tablet. Maybe the port is bad? Lots of "highly recommended" reviews. I went ahead and ordered one. It was less than $7. If it doesn't work, I still have the money to go forward with buying a new tablet. If it does, money saved! I went ahead and bought the "customers also buy" kit, with a replacement battery (just in case it's not the port), and a set of tools. If the cable is all I need, I'll have a spare battery. If the battery is all I need, I'll have a spare ribbon. If it still doesn't work, I'll go back to my original plan.
Just kinda bummed this is where I have to go now. Why would it suddenly just stop altogether like that? Is it because I keep it plugged in 95% of the time? Should I keep it unplugged till it's drained then charge it and unplug it again right away? I used to have to do that with an old cell phone. This is my first tablet so I dunno. If I end up needing to replace the whole thing, it'd be nice to know from experienced users what the best way to do it is, and what, if anything, I can do to prevent it happening again.

I'd suspect the battery is kaput.
It's not a good idea to keep the battery on permanent charge, there's no need. Let it cycle normally.

Well, all told this was an educating experience. I got the battery first. It came about 40% charged. Once it was installed I used TWRP to create a system backup and downloaded it to my computer. Then I left it plugged in overnight. The next day it was down to 30%. So the "charging" indicator on the screen was just a bunch of lies. I got the replacement charging port a day later and installed it. I didn't do anything else with the tablet, just left it turned off and the charging cable plugged in. It said it was charging, but again, after about 12 hours of charging overnight, the following morning it was down to 18%. So I'm returning both the battery and the port. They may still be working fine, and the problem is elsewhere in the tablet. I accidentally broke the little metal connectors over the power button (it's a contact sensor, and the connectors sit on top and complete the circuit when the button is pressed) when I took the back off to replace the parts. I also cracked my screen, although I think it's just the protector I put on it. I'm not sure what else to try at this point. The tablet is essentially a paperweight now. I can turn it on and watch the battery slowly drain to 0%, but I'll never get any more use out of it. So I decided to do a system wipe prior to putting it away for some future project to try and rescue it. Now it's stuck with the "Teamwin" screen flashing at me. I give up. I looked at Amazon to see if I could just buy another one, but they don't have any "new" left. They're all refurbished or "slightly used" from 3rd parties. I looked at other tablets, and bought a new Samsung Galaxy Tab S5E. It looks like it has the best reviews and marks. The only issue would be the wifi, but it seems to be a hit or miss with people. Some people say it's a problem, others say they don't even have a problem. So.. <shrug> I'll see how it works for me.
