I have two Pixel 4 XL, one white and one black. Both have the latest software update installed (QQ3A.200705.002)
I also double checked that radio and bootloader are identical.
Now the weirdness: Both phones are turned off completely (shutdown).
If I short-press the power button on the black one, nothing happens.
If I short-press the power button on the white one, the display shows a battery symbol for one second, then goes blank again.
How is that possible? Where is that different behavior coming from? I would expect the hardware and software to be identical.
What is your Pixel 4 XL doing when switched off? Do you see the battery symbol for one second when you short-press the power button or does yours remain dark?
Does the phone charge and power up? I did some searching and did find that plugging in charger at USB should show a battery icon, at least temporarily. More below. Also the screenshot below offers Pixel troubleshooting battery charge issues with a computer and data cable. See screenshot.
I checked my Pixel 4 XL with power down and battery at 25%. No battery indicator with momentary power button press. I did see the battery once when I plugged in with power off. What I saw from then on was battery percentage with dots in a circular pattern, animating when I press power button momentarily.
I'm thinking it could be something simple like battery % difference in the 2 Pixels? A more complex issue could be a battery indication warning. A quick battery test maybe?
There's been a few issues noted with Pixel 4 batteries, maybe not even limited to Pixel 4. Battery electrode terminals can crack if phone is dropped. Electrodes are too fragile, it seems. Others have noted carrying phone in pocket may induce battery or USB connector issues. Then there are the battery failures on Pixel phones.
I know I don't usually carry my phone in pocket unless I need to free my hands and I'm not wearing my belt pouch that I carry the phone in while away from home. My front pockets are loose in my synthetic sweat wicking shorts that I'm usually wearing most seasons due to mild weather most days year round. Only had the phone in that pocket a few minutes. I recalled it needed charging and connected to USB cable and walked away. Got busy and didn't need my phone for 3 hours or more. Still plugged in; when I unplugged it and checked notifications it had a moisture warning. Wording was something like ok to charge now and it did charge but I was oblivious to this the whole time it was charging. I looked at the USB port and saw nothing unusual.
Said all that to say best not to drop or carry phone in pocket. Pixels are fragile phones, it seems. Maybe there's a difference in battery percentage or past handling of phone that differs in the 2 pixels above?

My white XL doesn't do anything before showing the bootloader unlocked warning... which requires holding power for over a second.

Was the white one plugged in? If you plug the phone in while it's off it will turn on and act like it's booting. Then it will show you your battery before turning the screen off

This.
I just tested with my Pixel 4 XL.
I power it off. Waited about 5 seconds. Quick pressed power button. Nothing.
I plugged it in. Waited until screen went dark again. Quick pressed power button and it shows me percentage of charge on battery (I'm on Android 11 ßeta 1.5, so no actual battery icon, just the percentage and an expanding circle of dots).
I unplugged, and hit the power button again, same thing.
I waited about 5 seconds, and after screen went blank tried again, with it unplugged again. Nothing.

Thanks for your replies so far.
Both phones are in perfect working condition, e.g. there is no visible problem on any of them.
The behavior occurs without the charger plugged in, e.g. it is simply turned off without any cables connected.
Only apparent difference is level of charge, I will verify again once I charged both of them to 100% and see if that has an impact on that behavior.
But it is quite interesting. In switched-off condition, only generic firmware should be active, as Android or any other OS is not yet booted, not even the bootloader is running then.
So either there are different firmware/hardware revisions circulating or this is really weird.
Give your phones extended wait times after both:. Removing from charger, and powering off.
From Coral, with Tapatalk
I found the explanation for this behavior now:
It is purely related to state of charge and affects ALL Pixel 4 phones:
If the state of charge drops to a specific level, this battery icon will show briefly for one second if you short press the power button while the phone is switched off. It will no longer show, e.g. nothing will happen upon short power button press if the state of charge is above a certain level.
You can reproduce that by e.g. discharging your phone to 10% and then switching it off and perform that test.
What is the power level? I thought I did my test on a phone with ~90% charge....

Ok, I'm really sweating bullets here...
I had installed Cyanogenmod ICS alpha2 on my TouchPad and had spent all day on that tablet - loving the new lease on life it had. Before I went to sleep last evening it had like 10% power left. I plugged it in with the official Touchpad charger and left it charging until I woke up the next morning - a full 8 hours later.
To my surprise, it had 0 power left. Nada. Zip. I had checked the outlet and it was fully plugged in at both the tablet and the outlet to the wall. I knew I had turned off the tablet.
Now that it has 0% power - how in the heck am I supposed to boot into Palm mode to charge the battery (as I have heard that that is a work-around)?
I could really use your help here - many thanks.
@kstagg
Not sure if its the same problem...but I noticed recently that whenever i let my tp go down below 10%...and i hook up the charger...it doesnt charge at all...even with charger hooked up..battery drains....So when its 0% and I boot into WebOS to charge to fully....
For your issue, if your TP is dead...do you see battery sign when hooked to wall charger? if you do then wait for some time (mine takes 15-20 mins)...it will boot up..if your android is default then it will boot into android....without removing it from the charger...boot it into webos and charge...
If you cant do this..get it fixed by HP
What does it do when you plug it in?
First take the power adapter and twist off the bottom part and put it back on. When you connect it, do you get the battery "charging" symbol?
What I do is let it charge enough to hit moboot, then if I catch it in time I choose webOS and let it charge a little then reboot to CM, unplug the charger for a few seconds, then reconnect it. If it boots direct to CM the first time (moboot default) it's going to stay 'charging' but doesn't change from 0%. In that case, reboot and either go to webOS or reboot into CM9 a few times till it shows 1%... then disconnect the charger a few seconds and reconnect.
No matter what level the battery is at, if you boot into CM with the charger connected it will not charge. You have to unplug it for a few seconds and then reconnect it.
When I am hooked to wall charger, I see the battery symbol with the red line on it showing that battery is extremely low - in my case battery is dead. It won't even boot up when I take it off the charger. I just get the power cord symbol.
I have even been able to turn off the touchpad completely (since the TP has been on 0% power) by holding in volume up and power buttons simultaneously. I have no idea how I knew to do this - perhaps it was desperation. So I have even attempted to charge it via the wall outlet and waited a couple hours that way - but no change. It still has squat power.
Everything I've read is that once you've rooted the touchpad to a different OS, HP will no longer support it. Not sure where I would go to get it fixed by them either? Please correct me if I'm wrong. Hopefully it won't come to that though. Besides, the Mrs would kill me. :]

Just tried twisting off the bottom of the HP charger and reattaching and am just getting the power plug icon.
I installed CM7 in my friends TP back when that was the current release and about a month ago it went dead, wouldn't power up at all (no battery icon) and they still took it and repaired it with no problems.
In your case though I think you are fine... just leave it charging in that screen for a while. Then do a home/menu + power button reboot (15+ seconds) and see if you can get moboot. It may go back to the charging screen but thats fine, give it more time and try again. A few of my coworkers have the same problem sometimes and they come running to me, lol.

Guess you can add me to one of those unfortunate souls you can add to your list who keeps running back to you. :]
My question to you is - where did they take it back to? Do you have a URL showing a shipping address? Sure, HP HQ is a few miles away from me - but am not about to go knocking on their door and say "Yeah, uh - can you fix this?" Besides that is a corporate HQ - not a manufacturing plant.
I have two TPs and one (older one by about a month) has the connector going loose... It usually charges fine but once in a while, it fails to connect. Depending on the angle of the way the tablet meets the micro usb I will sometimes fail to connect it properly.
My other one has a very tight micro ubs port and it's hard to plug in, but it works fine everytime...
So my point is, make sure you have an actual connection when you plug in for charge.
Dunno if I'm just lucky or what, but my tp died on the way to work this morning, so I plugged it in when I got here, got the red battery symbol, and let it charge for about half an hour. Here is where I am now:

I should also note that it died in cm9, showed the battery screen, then when I checked it next, it had 7% or so in cm9 as well. Never had to boot into webOS for anything.

OK, did exactly what you said and plugged it in w/battery indicator in the red and walked away for a few hours. When I came back just now so far it was at 93%. Can I get a Hallelujah?
Ok, can anyone tell me what to do to prevent this from happening again in the future? Do I have to do any routine cache cleanup (?) or other general maintenance? Will booting into WebOS to charge before battery gets too low always work?
Thanks again folks-

Booting in WebOS before battery gets too low and charging in webos always works for me
Last time i drain my battery to 0% for the calibration. But it charges just fine after that.
Sent from my GT-I9100 using Tapatalk
I'm glad it worked for you! I would say just don't let it fully drain, lol. If it does, just repeat the steps and you should be ok. And you don't need to boot into webOS when it is low, you can plug it in while in android and it will be fine, as long as the battery isn't at 0% which is when it shuts off.
Mine is actually at the same point right now, fully drained.
Sometimes mine doesn't charge....because the USB cord gets ever so slightly slightly unplugged from the adapter.
Be sure to try that in the future.

Ok i removed battery and plug phone in usb now red led diode blink for 4sec but when i plug it which battery. Nothing
Was the phones charge less than 20 % at the time when you did the operation?
Use like a rubber band or something to tie down the power button and plug in charger. Should be able to charge up. Give it some charge and try to flash stock again.

USB charging mayby 30-50 % i dont remeber
How much time i must charg it beacouse when i try to charge this option ( i sit there 5 min) nothing like normal no led no charging animation
I thought I noticed when my phone has a low charge state, it does not want me to do things like restoring, updating core apps, or other significant changes to the system.
Charge it at least over night regardless what the charge indicator says.

Hi the problem is its say nothing no led no animation do not know phone charges
Guys is better i pull out battery then plug in charger wall than i put battery back and wait now red diode blink red always without stopping but phone dosent turn on
PS I gave him a charge later on but the LED does not light up but after 2 minutes she started to flicker about 6 times red then again shone red, and so all the time
Hi everyone,
I currently experience exactly the same problem. I wanted to flash my CM10.2 to the last night build (CM11) on my Xperia V. I boot into recovery mode and wipe data / factory reset and wipe some data from sdcard. I finally choose the "Restart system" option. The phone turns off but never restarted. I think I wiped some important files from system or kernet. I tried all combinations of keys (vol- + power, vol+ + power, only vol- while plugin in usb etc) but nothing occured. No LED, no vibration, no screen on. My phone was charged around 65% when I started operations.
I tried to charge my phone via the wall plug. No led. I wait during more than 30 minutes but nothing changed (I was expecting the back of the phone a little bit warm as it usually the case when charging).
As Ghost4Fun, I noticed that if I pull out the battery and plug the device with wall charger and then put the battery back, the red led blink red 2-3 times but finally turn off. If I pull out the battery, plug the device on usb and hold vol- + power during few seconds, the red led blink. It continues to blink even after release keys. If I put the battery back, the red led stay lit during 1-2 seconds before turning off.
This xperia v is not the first android device I change rom and it's not even the first time I flash this phone. I already experienced some problem during flashing with infinite reboot, device stucked on boot animation, etc but this time it's quite different as nothing happen with keys. Hope it's not bricked and someone could help us.
OK no help close thread... i will send to services f****** SONY

dm led red switch off than i try to connect to my pc but nothing. No now it isnt red led when pressing power button
I aslo tried quite a lot of configurations with keys and power source (wall or usb) but the only thing changing is the led frequency (~30s, ~45s, ~1m). I leave the phone charging during the entire night and some hours today but it didn't change anything. I aslo tried to let it charge with some keys pressed by an elastic (I read the problem can be related to a flat battery). I haven't been able to have another color than red from the moment it turned off the last time.
I don't think the issue is from the battery as it was 65% charged when it died and even if the phone is plugged for hours, the led color doesn't change and the heat is ambient. The problem is that if it's not related to the battery, it must be software and the only way to fix it, is to make the phone recognized by the PC.
I also plan to send back the phone to Sony but as I'm not at home for the next week, I have 7 days to try to fix it myself :victory: Does anyone already send back a phone to Sony in this state? I mean, my phone is (was ) unlocked, rooted and with a custom rom, I'm really not sure they will fix it (I'm sure they can but not sure they want). Maybe the data I wiped and make the phone bricked will also hide it to them :fingers-crossed:

Thanks for your link (there is a limit of 10 messages before a member can post external link so I can't quote you ).
I tried to plug my device to the pc with the rubber on the volum - button during 15 minutes without any chance to make it recognized by the flashmode. I will plug it to the wall charger for the entire night and will wait. I never thought a battery can be as long to charge. If someone has the technical reason of this long charge when a device is bricked, I'm interested by the answer.
I will update you as soon as I have news.
@Ghost4Fun i think it is because of the broken boot.img inside the ROM, use FLASHTOOL, put the devices in fastboot mode then flash a kernel, maybe NK Kernel, it has recovery http://forum.xda-developers.com/showthread.php?t=2223534

Does anyone have a solution for keeping the screen on when wirelessly charging the N6? The problem seems to be that once full the phone stops charging and the screen will turn off. This is annoying when using a Qi dock at night.

That won't work.
The problem is that the N6 completely stops charging when it reaches 100%. Compare that to the Nexus 5, which would go into "Trickle Charge" mode, but would always show a charging indicator as long as it was on the charger. This one simply stops charging, removing the charge indicator. This causes daydreams to stop (as well as the "Stay Awake when Charging" option), because as far as it's concerned, it's been removed from the charger. Once the N6 reaches 98% (or so), it will start charging again. The phone will come on, and if it stays on long enough, will even go back into daydream mode. However, as soon as it hits 100% charge, it repeats this process.
As far as I know, there's currently no fix for this. Google needs to set the N6 so that it still considers itself to be charging as long as it's on the wireless charger, like the N5 did.

Exactly... Hopefully there'll be a fix for this in the future.
i dont use daydream but i have the option ticked to keep screen on when charging.
i use a qi dock with an indicator on the front. blue when charging. green when not.
when the phone is full, lightning bolt goes away, charge lamp on the qi dock changes to green.
then as it need to "top off" the phone, the chargers lamp goes to blue, lightning bolt on phone pops up. tops off.
rinse. repeat.
what am i missing?
what docks/chargers are you cats using?
I have to same type Qi charger when it's green the screen will turn off after the prescribed time out period. That is my issue and I have keep screen awake while charging on in developers settings. I want the screen to stay on when full, green light on, currently my workaround is Tasker but apps like "Stay Alive" will also work.
Someone has posted a bug report for this issue. Hopefully it will be fixed. https://code.google.com/p/android/issues/detail?id=85538

The problem is, what do we use to end daydream?. In use a qi and this is really annoying me but realistically there's not a lot that can be done without tasker.
Also daydream isn't really the same as "screen on". If the screen doesnt time out, you'll never get to daydream.

Can I ask what settings you have used in Stay Alive? I have tried using it, but my Nexus 6 still turns the screen off once the Qi dock has charged it to 100%.
UPDATE: Sorry, it was me being stupid. I had a Llama task which switched off the screen when the phone went from "charging" to "battery". Once I disabled that task, Stay Alive is working fine and the phone stays on.
Question for you, does the nexus 6 turn the screen on when the charging kicks in?
Picture it connected to a solar charger where you're walking in and out of the sun light..... My nexus 5 would always kick the screen on which would drain my battery.... Nexus 4 didn't do that... When charging I think only an led would light up...
I wouldn't keep the screen on a static image for an extended period of time for any reason, because amoleds burn in.

Was this a response to me?
I'm trying to find out if the Nexus 6 turns the screen on when it's plugged into to charge. Or if the screen stays off when it receives power....
Hi,
My HTC One has started turning Off as it goes below 30% and does not powers up until plugged in to charger. When i plug in charger it shows charging and 0% indication.
How can i rectify this ?
I too have seen that the device does not properly indicate the REAL battery level. Mine usually turns off when I am below 10%.
Yeah I'm sure there's a thread that solves this issue, I'm looking for it too. I've been having crazy battery issues, such as the phone randomly changing it's mind on the battery level. For example if I restart the phone (may have to do with if I was charging it or not) the battery either goes up to max, or sometimes goes down to ZERO and won't even start up (pre reboot it would be near 50%)
I think this happens because of using a ****ed charging cable. I have two main cables that I use, with the original HTC adapter (no longer have the HTC wire though, so I use the one from my Nexus 7). Over time the Nexus cable got damaged, and even data transfer was extremely slow and unreliable.
The funnest part? When I charge my phone and it's at 90%, and I restart and it claims 100%, so I power down and it keeps charging for another 10 minutes or so and finally the LED turns green, only to turn it back on and it claims 97% and keeps charging.

The funnest part? When I charge my phone and it's at 90%, and I restart and it claims 100%, so I power down and it keeps charging for another 10 minutes or so and finally the LED turns green, only to turn it back on and it claims 97% and keeps charging.

HTC one M7 & M8 battery reset and calibration: http://forums.androidcentral.com/ve...ry-charger-reset-procedure-htc-one-m7-m8.html
Follow it to the letter, skip "Turn off Fast Boot in settings" as it no longer applies to our phones, unless you are running an old rom.

I tried this but it does not help much.
Is anyone else experiencing a problem with their phone randomly switching off? Mines turns off at random intervals regardless of battery and when I turn it back on a percentage of the battery level drops. Please see link below for screen shot

I already tried the above mentioned instructions to recalibrate the battery but it's not helping.
HTC One Turns Off at 30% Battery
I Am facing same issue. when battery level is on 30% then phone goes suddenly off. I have done catch partition in bootloader for calibration of battery but it is not permanent solution. I think there should be permanent battery calibration is solution but I dont know how to do it
My htc one m7 also turn off using 30% battery only i purchased a battery and give it to mobile shop but they are unable to change it and asked me to go htc service centre but i am out of warranty and trying to contact some private service centre its not an issue that can solved by yourself or doing battery calibration now i am using my phone with a 10400 mAh powerbank i will soon contact service centre or buy a phone with removable battery if servicing cost too much

Try another phone shop, any good shop should be able to replace your battery. There is a lot of uni-body phones nowadays, good phone shops know how to deal with them.
I got a Redmi Note 11 from Amazon.sa on 8th June 2022 (17 days old) and the phone was working absolutely fine until today.
My phone ran out of battery as I was outside. When I came home to charge my phone, it was charging but not turning on anymore.
I can see the battery sign while charging but when I'm pressing the power on button for more than 10 seconds, it's not turning on.
I tried to use a different charger and kept on charging overnight. I tried fast boot but it's not entering fast boot mode. Attached are images and videos

This happens to people who live life on the edge and take the low battery warning for granted. Happened to me once. Lesson learned. Never use a Li-ion battery till 0%.
This happened to me on Redmi Note 11 4G
I was doing battery drain test and suck up the battery to 0% and when i tried plugin the phone with the in-box charger the phone do show charge but percentage don't bump up.....
Solution :
1.Open the backpanel via heating it to loose the glue
2.Removed the middle frame
3.Disconnect the battery connector
4.See the + and - symbol on the battery connectior pin
5.Disconect the battery and Carefully try to try to charge the battery directly via 5V 1A cable ( find old usb cable n cut in middle u will find 4 wires,2 wire [red+,black- ]for power and 2 wire [ green n white] for data...we need only red+ and black- wires put the one end on charger and connect the positive to + point of battery and negative to - point of battery used septic pin but carefully....
note the + and - marks are mentioned in battery connector pin and on mother board ..
charge it carefully for 3 to 5mins ...when the battery will get warm conncet the battery conncetor pin and bamm charge ur phone with inbox charger
Don't puncher the bttery....whlie using septic pin

The charging battery voltage limit is 4.3V. Charging it with 5V could make it unstable and even explode. But doing this for shirt time just to bring it back to life wouldn't hurt it. Just don't leave it for too long.
