I got a Tab yesterday without any cables. There was a little amout of battery left so i Rooted it and bought the "Euro Tap Bootstrab", i tried it, boot CWM, took a backup and then i turn it off. No battery left.
I got a USB cable today. Plugged it in my pc and tab, but I honestly cant see if charging or not. Sometime comes a large battery icon, but when pressing button it goes black
Cant hard reset.
Please help

A PC will charge it very slowly. You need to plug it into a wall charger. You probably didn't brick it. See if you can get a USB wall charger from somewhere. Usually Blackberry chargers have a USB port that you can plug the cable into.

Using my HTC usb charger, thanks! So I just have to wait now?

Yeah, pretty much. I don't think backing up your Tab would have bricked it, even if the battery died mid-backup since you're reading from memory (internal), not modifying it.

Ehm, to be precise, I pressed "Reboot System", a samsung logo popped out, I waited a long time and it didnt change so i turned it off. Dont hope it's bricked

Just what!? I've charged it for about an hour and have litterly tried everything, this suck big time! It just wont start

Just plugging it in HTC charger gives you almost nothing! Original Samsung charger has a "trick" inside - it has pins 2 and 3 of its USB output connector shortened, and on top of that it has also 2 resistors between these pins and +5 and GND pins. When you plug the cable in common charger the tab does not "understand" that now it must take full power from the charger and does not charge the battery actually (it should take appr 1 A current from the original charger for 4 hours to be fully charged). You should get an original charger, or get a special adapter connected between your HTC charger and tab's cable (I have seen some at Amazon.de), or to make an adapter yourself.
PS. There is a strong recommendation: never do any programing, flashing, backup or restore with battery discharged below 80%, better to do it with charger connected.

Thanks, good to know, however the orginal is lost.. so can i still use the HTC but it will take longer or?

I am afraid the tab will "think" that there is no charger at all. Connecting it to USB port of PC may give a result after several hours (very-very slow charging). Why don't you think over getting (or making) an adapter?!

Will defo get one, but then I would have wait till monday
Don't think i can make one

Actually I have made this adapter in 20 minutes (but I am formerly an electronic engineer, though).
Well, then try to connect it to PC for the whole night (do not forget to keep PC running ), maybe it works out...
First try to run it, if it hangs, try CWM/restore, if it is bricked - re-flash it.
Good luck!

Thanks alot, really! Will report back tomorrow. Again tanks

Just to be clear, when it's charged, does the battery icon have to be there all the time? It does disappear after some while when it's connected

Battery icon disappears in several seconds when the tab is switched off. Short pressing on power on button shows it again for some while. Moving dots under icon show charging in progress.
When the tab is fully charged it makes a short sound.
When the tab "understands" that it is connected to a charger, it also makes a short sound.
PS. After recovering the unit I recommend to install Battery Watch from the Market - it has a widget and you will always know the state of battery etc. And you can see a graph showing a battery behavior. And this application is on top of that shouting - "Charging started!", "Charging complete!", which is funny...

Guess mine doesn't charge?

Sorry for delay - no, it does not charge... the reason was explained.

Yeah i see now. Thanks for taking you time. Defo appreciated

Just for reference, do NOT turn your GTab on while charging from a pc. It won't charge at all. Keep it turned off, and then wait for like 9 hours (it takes about 50 minutes to increase the charge to 10% from my laptop).
And when you flash, always have a full charge. ;-)

Hehe, yeah I just couldn't wait
Gonna pick up a HDMI dock tomorrow, until I've connected it to a laptop to see if it will charge.

So i got a proper charger, but does it charge?

[Q] Touchpad ICS down to 0% Power

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.

it happens to me one time, I pulled out the charger for 20 seconds and its was ok...

That's not a problem, its just like that.
The pc it's not so "strong" (500 mA) as the normal charger (1.2A).
Don't worry, be happy

Of course I have the notification, it's normal.
What it's not normal is receive the same notification in a normal charger.
Even when I charge with the Samsung Wave GT-S8500, with 0.7A the phone don't give any notification, it just charge normally.
Try to use other charger and see if the problem remains, check the output cause if it's 0.5A the notification will appear as well.

Same's happening to me. LG has changed my phone via warranty and this phone is saying slow charging from normal charger. I tried using different chargers but it keeps appearing. While iI watch mvies on my phone the battery goes down even it's on the charger.
EDIT; I figured it out it all depends on the phone's temperature. If it's too hot it will never charge that fast to avoid the heat. I wouldn't care about it but it simply annoys me that I can't play or watch movies continously.

Is there anyone else with this issue or already fixed it? I flashed 10e yesterday and i started getting it too.

Maybe I solved the problem of slow charging. You must use a higher quality (thick) cable USB.
I had such a problem, two months after purchase. But I used unoriginal cable between charging and phone.

For me was a little hardware related problem, i solve it performing the following procedure, in the port of the phone, with a little blade screwdriver got a little up the middle connector as described in the attached image, and for the cable did a small narrowing in the micro USB connector, so you can see in the pictures, I hope will be help.

Was also having problems connecting the phone to pc, I hope will be helpful.

Slow Charging
I had the same issue.. I am currently on stock rom 20a and this issue started to appear after I flashed the stock rom. After a lot of RnD on difference forums, I tried every possible thing.... changed the charger (wall charger), changed the cable, even tried charger with higher output, reflashed the rom...but nothing worked..... considering the last resort of using the blade screw driver and tried straightning the pin inside the phone and guess what.....it finally worked.:laugh::laugh::laugh::laugh:

G Watch R on Wear 2.0 - Won't turn on unless it's on the charge base

I've officially had it with Wear 2.0, all of the good stuff is gone, but what's really winding me up now is the problem where I turn the watch off overnight (if I'm not near a charger) but I cannot turn it back on the following day. I see the LG logo with the padlock at the bottom, but the watch will not continue to boot and instead shuts down. There is more than enough battery (probably >50%).
Does anyone else have this issue?

Managed to edit and delete my post grr.
Basically same problem as you, info in the post above from adb shell regarding battery. Perhaps someone with a working watch could post there's so can compare.
To get your watch working try
Dumpsys battery set level 5
Dumpsys battery unplug
Since i did this watch has been off the cradle for 20 mins.
To reset the above
Dumpsys battery reset
Funny how this only started with aw2.0 ota update, prior to which was getting 1.5-2 days.
Perhaps something's corrupted somewhere. I did think the misc partition, tried to download it, to look at it can't see anything but zeros from DD bin file i made.
Tried reflashing, factory images, taking the back off disconnecting reconnect, run down in fast boot mode to nothing, downgrading, reflashing aw2.0, nothing has worked.
Doing the commands above could damage something so do at your own risk.

Update: failed at 2028, vibration went off caused it to turn off. Must be failing battery unable to provide sufficient current. I've ordered a new battery from eBay.

Was board so rigged this up (was described on another forum post but using a proper bat charger), left it connected for just under an hour, disconnected on rise of battery voltage.
I wouldn't recommend doing this.
Anyway watched booted up, fully off the charger after. Leaving it on charge for a while, will report back on experiment

Same Issue
So is it working now? What did you EXACTLY do?

Yes working correctly now battery back to normal. Basically butchered a usb cable and rigged up to power as in picture above. Temp solder wires to battery.
If your going to do this make sure battery doesn't get too hot, expand or explode

Wow that's quite extreme, I guess? But I think Imma try other methods available first. This would be my last resort. Anyway thanks

There is definitely an issue here. Mine just started doing the same thing...

I ended up getting a new battery the old was working ok after rigging it up as my post however long term it was an old battery dated 2014
Sent from my Moto G (4) using Tapatalk

Same. Started having odd issues. Would not complete boot off cradle, powering off when removed from cradle or not booting at all on some kernels, etc... Fresh battery seems to have resolved all of it.

I had the same problem, tried factory reset a few times and flashed different kernels. Watch shut down as soon as I removed it from the cradle, however I removed the usb from the PC when the watch was in the cradle and the watch didn't shut down. It stayed on when I removed it from the cradle with the USB unplugged. Coincidence or maybe powersurge when removing the watch with usb plugged in?

Hey all, I'm having the same issue where the watch doesn't boot if it's not on the cradle. I've tried formatting and reinstalling multiple times but I still have that issue for some reason. It looks like once I boot into TWRP and take it off the cradle, it stays on. I'm going to try to drain the battery in TWRP and charge it up again in AW.
EDIT: Fixed it somehow, it seemed to work without the cradle when I would "fastboot boot" into official boot image and then take it off the cradle when it turned on.

Ok. So I've been following threads here for a while and i finally bought a new battery from fonejoy and had it replaced today...
I still cannot get past the android logo. It's the overheating. If i put the watch in the fridge i can boot up fine and the watch remains around 50 degrees celcius. Once it gets to 60 it shuts down. And it easily gets to 60.
Can someone please help me out?

I still cannot get past the android logo. It's the overheating. If i put the watch in the fridge i can boot up fine and the watch remains around 50 degrees celcius. Once it gets to 60 it shuts down. And it easily gets to 60.
Can someone please help me out?

For me, new battery solved the problem too

could you please explain how you did it and which "Official" boot image you mean ^-^ ?

Sorry for the late reply, I just noticed this message.
Basically the official boot image is the single core unmodified version that is posted in the forum here. The problem was that the kernel with 4 unlocked cores was putting too much stress on the battery. In the end even the single core boot image stopped working well so I bought a new battery.

Just saw this and trying to see how long it will last back on stock kernel... earlier wouldn't boot up but when booted from fastboot was ok but went into shutdown trying to download July's patch
Flashed back stock kernel and see how it goes
PS: anyone knows where in Malaysia the replacement battery can be bought as the local LG service center has no clue about it

Power off when removed from cradle
I have this issue ever since Wear 2 as well.
Bought a battery and replaced - problem now even worse - won't even stay on in cradle. Put original battery back in and it's still a problem, but not as bad as the new battery.
Contacted LG about this - they said they only repair in warranty, and referred me to a sub company called SBE. SBE say they no longer repair them.
Lots of heated emails between me and LG's Customer Service with no result. Basically if you own an LG product and it's out of warranty - it's pretty much time for the bin as far as LG are concerned.
Pretty disgusting service in my opinion. You expect a £200 watch to last longer than a 12 month warranty period - but LG won't budge.
Oh, and LG say they have never heard of this issue! That's either a lie, or they never read forums!!
Not sure what to do next really - but here is what I won't be doing:
I won't ever be buying another LG product!

Pixel 4 XL loses battery power

My pixel 4 XL literally lost 6% battery power after just a restart. I know letting the phone die completely is actually bad for the battery but should I actually do that to reset my battery? Losing 6% battery power in less than 20 seconds of restart is very strange. Anyone else have this problem and what did you do to fix it? Thanks in advance for anyones help with this.

I lose 2 or 3% each restart. It's really weird and consistent. Happens every time. Can't figure it out either.

restarting the phone causes a lot of stuff to happen and depending on your apps, they can all be started during the boot

I've been with Android for 10 years and no phone I've ever had goes from 100% full power plugged in to 94% in just a restart...

I don't think so it has anything to do with battery consumption. It must be faulty battery counter where the actually battery % is not what you see and after a reboot the numbers are reset to the original battery% number. That's what i can think of

That would be fine if the phone wasn't on the charger all night plugged in. There's no way a phone should drop 6% being at a full and constant 100% charge plugged into my wall charger. If the phone was off the charger at night I might understand the drop after a reboot to correct the percentage.

But you might want to consider the possibility that charging stopped at 100% which wasn't obviously 100% in real. If it had dropped 6% straight away then i feel what I'm saying is correct.
You might wanna try to reboot by pressing the power button for about 40 seconds or so. You should have a reboot first and then it will vibrate and reboot again. That would reset the better stats but don't leave the power button until you hear there vibration after first reboot.

Starting apps, checking filesystem, turning on radios and reconnecting and registering with cells/wifi, starting the GCM sync tasks... and lots more.
Why would it no use a few percent of battery power restarting? My older tablet chews up 5% on restart is sluggish for first couple of minutes why the play services does all the background sync and backups.

Tried that trick you said to do, I didn't feel any vibrations although I let it restart three times while holding the power button down. Maybe that reset my stats. I'll know later when I wake up and take the phone off the charger and reboot if that did anything for me.

Sure let me know! If it happens again i might know why.

So I think it worked even though I didn't feel a vibration. Only lost 1% restarting now

Great must be the faulty indicator stats. Although i was thinking it could also be that your phone stops charging at 100 and drain till 90 and start charging again.
This was the pattern on my Xperia before to avoid overcharging. Pixels might be doing the same if you put it for overnight charging.

Does that restart trick work for other phones too or just the pixel line?

Should work or if they have any other way to reboot incase of a phone freezing then that method should also work

Ok thank you for your help, I'll tell others to try the trick if they have batteries falling fast

Lithium batteries do not have a battery memory, so there's no reason to fully drain a battery and then fully charge on any regular basis. Use and charge as needed.
It's also not normal for a phone to drop that much on a restart unless there is something wrong with either the battery or the power management circuitry.

Seemed to work for me also
I rebooted twice. First time after 40sec hold down and I lost 1%. Second time I lost 0%
