[Q] New G3, cannot boot/restart without charger - G3 Q&A, Help & Troubleshooting

I've bought an LG G3 today. Everything worked fine at first, but then when I restarted it for the first time this happened:
Device boots
Lockscreen is visible
Asks for pincode -> I enter correct pin
Few seconds later screen turns black..
After the screen turns black, the only thing I can do is remove battery and try to boot again. Or plug it in to the charger.
If I plug it in to the charger it shows a battery icon in the middle of the screen and when I press the power button it boots, and does not shut down after it's fully booted.
I've read the other shutdown thread but it looks like that is not entirely the same issue I'm facing?

Have you customized anything? Sounds to me like either a bad battery or a faulty device. Take it back to the store.

It's rooted with TowelRoot and exposed installed, just installed - nothing changed yet. Today I was not able to reproduce the issue when rebooting. Although it did shutdown when I just tapped send in the default messaging app.. Couldn't get it back on without plugging it in to the charger. Battery level was around 25%.. Removing the battery also does the trick.. So it looks like it totally freezes..
When I got the device, I immediately started configuring and testing it and only charged fully when battery level was +- 25% (started out at 45%).

Definitely nothing normal about that. Return the device for a new one.

My G2 will shut itself off - any suggestions?

I'm looking for any ideas for the problem I'm having on my G2. I'm afraid it's a hardware problem and not much I can do about it.
I started having problems after upgrading from CM 7.1 to 7.2, but I don't think it was related to the upgrade. I started having battery draining problems, the phone took forever to get fully charged, and car mode would automatically start sometimes when plugging up or unplugging the charger. I cleaned the usb port with alcohol (with battery removed), let dry, and restarted. Now I don't have the car mode problem and the battery problem is somewhat better.
My problem now is that the phone will just die when I'm using it. Usually when I'm using the browser. I'll be scrolling on a page and the phone will just turn itself off. Like the battery died. I can turn the phone back on and it will start up, get all the way started back up, but while it is still loading the home screen widgets, it will go off again. I can repeat this several times. The only way to recover is to plug in the charger. I don't have to hit the power button again, just plugging in the charger will start up recovery mode automatically, I'll choose reboot and the phone will start normally then and stay on.
The phone never dies when I'm not using it. I'll carry it all day, making phone calls on and off, and it'll stay on with no problem. Mostly, I only have the problem when using the browser. Also had the problem while using my newsreader. Once during playing a game. But if I start up browsing the internet, it doesn't take long before it will turn itself off. A matter of a couple of minutes. I don't have the problem with reading emails with K9. Don't have a problem in downloading from the internet such as podcasts. Don't have a problem in sending text messages. Don't recall it shutting down while using the Facebook app. After putting up with this for a week, some troubleshooting and observations.
I never have this problem if the charger is plugged in. Only when it is running fully from the battery.
I've tried swapping to a different battery.
Turned down the overclocking with no difference.
I've changed to other recoveries, CM 7.2, CM 7.1, a CM 7.1 that I was running in May. No difference.
I've swapped memory cards.
I've reset battery stats.
No difference if running on wifi or just data.
Clearing caches made no difference.
So, I start thinking it must be a hardware problem, but then why does it only crop up when internet browsing. Must be power related since plugging in the charger makes it go away, but why does it not have a problem with using the phone in other ways?
Any suggestions on what I could try?
You could try to see if there is too much voltage drop when you start something power-hungry. Use a battery voltage logger and post the results. Start logging, let the phoneidle for a minute and then start browsing. Even if the phone shut off, the log should still be there after rebooting.
Thanks for the idea. I can't locate a logger that looks like it would work. It would have to capture a quick drop in voltage that is momentary. This problem happens even on a full battery and when the phone come back on (either momentarily or after a recovery reboot) the battery level is unchanged.
You might try as well an other way: first idle, then gradually step up to a more power hungry app to see when the problem actually happens. I have no other ideas...
Make sure that you dont have any contact with the battery and the door.
Normally batteries are covered with an aluminum wrap, and can cause short-cuts with the phone itself.
I searched it for a while with the galilio batteries.
You can try to put some saranhwrap around the battery.
I have the same problem with two different batteries. But I'm ready to try that too.
Battery graph
So here's a graph of my battery status. Long time to charge to 100%. Discharges pretty rapidly. Each downturn ends in the phone turning itself off. Notice that at 7:30 today, it turned itself off, I did a recovery reboot, then noticed it wasn't charging very well (green line turns to blue but doesn't increase), then I did a manual reboot and when the phone restarted, it showed the battery was at 100% charge (from about 60% before the reboot).
What do you think - hardware or software?

Well, I just took the cover off for awhile and tried it. Played crosswords (Shortz) for awhile with no problems. Started my newsreader (Newsrob) and it shut itself off in about 15 seconds. So, no short to the battery cover.
Same thing is happening to me. I use poweramp or the browser and the G2 just shuts off. Then I restart it and it tells me that the battery is low. Once I shut it down and reboot in recovery and wipe the battery cache it's back to it's normal battery level. I disabled data and set my phone for 2G networks only and it didn't shut off after. I'm assuming this is a wireless issue? I'm running mimicry 1.3.0 on my G2.
Had the same problem. Swapped out batteries and problem gone.

Did you swap the battery and immediately have no further problems? I tried swapping my battery already and still have the same problem.

false full battery with random boot loops

I have this problem: youtube.com/watch?v=chvRbwgT9n8
Sprint Galaxy S3, unrooted, stock
Basically one night my phone would not turn on after the battery completely drained out. Put on charger but phone would not turn on. Did the spin test on original battery and it seemed busted. Ordered a new battery, put it into phone, charged for a couple hours and have the same problem the above youtuber does. The battery icon looks identical (both the grey and ~90% one).
1) If phone is unplugged nothing happens, can't start into recovery/download/boot.
2) If phone is plugged in it will show grey battery icon for like 10s, then go to a green battery screen where it shows the battery is ~90% full. The red charging light stays on.
3) I can boot into recovery mode if the phone is plugged in but if I try to normal boot the phone it will 50% get to the S3 splash screen, vibrate, and then turn off, and then 50% of the time it will boot to the home screen but wifi and data will not work (the battery icon will show 100% at this point). After a few seconds the phone will vibrate, turn off, and return to the grey battery icon swirly and then back to the 90% green battery screen.
4) I've tried wiping cache and doing factory reset but doesn't seem to phase it.
5) Reflashing via Odin to stock doesn't fix issue.
Any ideas? It doesn't seem like the power button issue because usually in those cases the battery shows as low or it will be stuck in a constant repeating cycle. This just seems like the phone is not drawing any power from the battery. Thanks.
Update: so it appears that the longer I leave it on the charger the longer I can use it while connected. The issue now is that Wifi and data will not enable, sound intermittently works, bluetooth doesn't work. I found someone else with _exactly_ the same issue and symptoms who had a weird fix:

OK, Czech this out, I took my sim card and SD card out of the phone and tried to start it, and guess what? IT FREAKING CAME ON!!! It obviously wont function without the SIM card, and it prompted me to turn off the phone and reinstall the SIM, but after doing that, it started right back up like it was new.SO EVERYONE GIVE THAT A SHOT. We'll see if it gives me any issues.

The problem for me is that the Sprint version doesn't have a SIM card and I'm not using a SD card. Is there any reason for this madness?

[Q] Can't boot up SmartWatch 3

Guys,
I've updated my SmartWatch 3 to 5.1 yesterday via OTA
Everything worked fine.
When battery was low, I charged it up from 9% to around 80% (I switched it off though)
It stuck charging at 80% as it was very hot I removed it from charge.
After 2-3 hours I charged again to complete from 80% to 100% even after 1-2 hours of charge It would not charge.
Today morning I did the same I wouldn't charge. I switched on the watch I got android wear logo and it directly switched off.
Now it's not switching on.
Any help I can get?
Yeah same issue here but it is harder than that ...
I installed TWRP on my watch, and when I received the 5.1 OTA, it seems that it did not want to install the update because I was not on recovery stock. Then, my SW3 started to lag, I was not able to install the ZIP via TWRP, and it was superhot, I was unable to boot Android Wear..
That's so ****ed up, man. I can't even know what should I do. xD
I've got the same (or really similar) problem my watch was out of battery, I put it on the charger, it showed normal charging battery icon, then when I tried to turn it on it doesn't show anything, the display is black and when I held down the power button it vibrated once. The problem is that it isn't only display fault because I can't connect to the watch with my mobile phone. Wat do?

edit: Well that was weird, I unplugged it from the charger and put it there again and now the charging icon is back and when I pressed the button it started to boot. Weird.
Me, too.
After OTA today, my watch is dead. Even long press power button can make freeze screen reboot.

Okay guys, here my solution, it worked for me :
If the screen of your SW3 is completly dark:
1) Just let it plug. In fact, the watch is charging, it's just not shown up (I dunno why...)
2) Let it like that for 1 hour, and then unplug it and let it cool down for 10 mn.
3) Install the Sony Companion App on your PC.
4) Keep ressing the power button of your watch til a screen with the watch and USB appears.
5) Plug It to your PC, open the Companion App.
6) Somewhere in the menus, you can resinstall the OS of the watch, RESET it, find the menu.
7) Let your watch restart.
And you're done ! It worked for me, so try.
I left it aside from morning to evening. Didn't even touched it. It completely discharged. So I kept to charge once again and it magically booted up and now working fine. Seems pretty weird. ?

As I read in other post, I can confirm there is some kind of bug when you are charging your SW3, if you turn it on with the usb cable charging and the screen showing the battery %, the smartwatch gets like frozen and doesn't do anything.. In case you have this problem, you should wait until the battery goes to 0%, start charging your sw3 BUT when you are going to turn it on again first unplug the usb cable and wait until the battery % display dissapears.. I did it after I read it in other post in XDA (I don't have the link here.. I was searchig for it on another computer) and worked for me.
I hope it works for all.. sorry if my English it's not perfect hehe

Battery Level stuck @80%?

I can not seem to clear my Issue of the battery always showing 80%.
I have reflashed back to Stock, but still the same problem.
Even when I had TWRP recovery installed it showed as 80%.
Any ideas how to fix this please?
you have infinite battery, be happy!
I wish
Fixed it by flashing Open EU H815.kdz file once again and now the battery use is showing correctly.
Edit: The problem is back again!!!!
After several hours when it seemed okay, I put the phone back on charge and Bingo.
Stuck back at 80% again, even on my other original LG Battery, and to top it all i have a stuck LED on faint green.
WTF???
I had the same problem before, how many apps do you have installed? Does it charge in safe mode? If not, does it charge to 100% when the phone is powered off?
Tried Safe Mode and the same problem persists.
The battery seems to charge fully but the OS is not showing it correctly
Hmm, in my case, it was always stuck at 74%/75% and it doesn't charge more regardless what the indicator says. What about if you powered off the phone and charge, does it actually go past 80% and to 100%? I fixed my problem as I had 739 apps installed incuding system apps so I greenified everything except for those I needed and that fixed the problem, not only am I getting more than 2 hours of battery life regardless if the screen was on or not, it's now 12 hours or so of battery life with a few hours of screen time but the charging is fixed. Before I used to also have problems installing in Google Play Store, it would actually sit there doing nothing after the download and install when it feels like it even after a hour or it can install fast.
Tried charging while turned off and still gives the same reading.
Last night I reset the phone and left the battery out for 30 mins before re-inserting and setting up the phone once again.
So far it seems to be fixed and showing correct battery %.

Sure, see attached.... Please note that I am including the system apps in the app count as this is what's reported by Titanium Backup *root. I was wrong, I seem to still be getting the stuck battery percentage indicator which can happen at 73/74% or even 97%.
It seems the stuck battery charging % problem came back when I changed the brightness to 100% Auto but went away when I changed it to 0% Auto. I had the problem at 38% Auto too.
Is there any workaround? I just flashed my LG G4 from 10a to 10e and Rooted it. And It happened exact the same.
After a reboot I didn't have Service IMEI Null . This happened twice in a row, after that it magically resolved and now I have Service and IMEI... But after some reboots I started noticing that LED green turned on and the 80% Stuck Battery....
Im experiencing the same issue battery stuck at 80% and green led stuck on. Issue went away however battery life was appallingly bad, went from 1.5 days battery life to struggling to last a day. Battery stuck at 80% has come back today.
I have tried factory reset, upgrading from 10c to 10e.
i'm having the same problem: battery level stuck at 80%, network set to 3G but not actually connecting, and the inability to charge the battery when it is in the phone - even though it says "charging" the percentage kept dropping (tried different chargers, cables, batteries, and even wireless charger - i can only charge using a separate charger). the battery not charging started about a week ago. the 80%/3G issue started this morning.
no root or any other mods, very few apps installed. i've had the phone about 6 months. verizon. 13B. 5.1.
i did wake up the other day to a frozen "firmware update" screen, but it has not come back, and i've checked for updates (to 6.0 maybe) with no success. this "firmware" screen was after the battery stopped charging, but before the 80% problem. i had to pull the battery after it sat there a few hours (it said "don't disconnect USB" even though USB was never connected, and there was a progress bar at 0%).
UPDATE: this thing may be falling apart in front of my eyes. now my service is disabled and I have no network connection showing up at all.

Try taking the SD card out, if that doesn't work take the sim card out and then back in. That normally gets the service working again for me.
I had this same issue and sent it back to the supplier, they than forwarded it onto LG who couldn't find any issue with it. Im now waiting for it to be sent back to me.
Are you using a 3rd party (non-OEM) battery by any chance? I ask because I had the same issue occasionally when using a non-LG battery. It would fix itself after a few reboots or by installing the LG battery that came with the phone. I truly believe based on my experience, and others (there is another thread related to this exact problem) that the issue is purely battery related. Even the service disabled symptom.

I don't have a 3rd party battery so I don't think that's my issue
OEM battery for me. I did remove SD card, and reseated the SIM: no help.
This is my current work around: Turn off phone. Charge battery to 100% with phone off (overnight). Turn phone on.
It seems to charge fine (and have accurate %) when the phone is off. Then it powers up with accurate battery percentage and 4G coverage. Note, I've only tried this twice, but it worked both times.
I'm having the same issue. Battery stuck at 80% and green constant notification light. Not rooted BTW.
I assume LG will investigate the issue while I am stuck with no phone for weeks.
I should have never bought a non nexus phone...

1st Gen Moto360 Essentially Not Working

So, I got a new phone...Galaxy S8+. After like dozens of attempts to factory reset my 360, it finally booted correctly. Now when I try syncing things, nothing happens. In the Wear App, I don't even have the option to select a watch face. After undocking the watch (which is fully charged), it just shuts off until I redock it, at which point it boots up as it was turned off. Is this thing toast, or is there a trick to this? Never had this many issues with this before.
Anyone?

Ah ? thinking you said : After undocking the watch (which is fully charged), it just shuts off until I redock it,
so when watch is not on charger it shutdown ?
You're misunderstanding my issue. Nothing is syncing to the watch, and the Wear app gives me no option to pick a watch face.
I tried resurrecting this again, but it's still having issues. Popped it on the charger, and it acted like it was going to start up, but went into a charging screen. Eventually it'll boot back up, but when I swipe down and start swiping right to get to settings to do a factory reset, it just turns off after a couple swipes. Is this thing just dead? Battery is over 60%.
Your battery is bad. It shows good battery % numbers, but it can't provide enough current to keep the watch running when off the charger.
Replace the battery and it will fix some, if not all, of your problems.
