Why does my phone act like it's plugged in all the time...

Just got my phone yesterday. Running Calk's 2.7 and ICS theme, set dpi to 160, looks and runs awesome. However, it always thinks it's either charging or plugged into USB. the red LED never wants to turn off. how can I remedy this problem?

Possibly try turning it off, booting to recovery, clearing cache/dalvik-cache, and then clear battery stats

Was it like this prior to rooting and custom rom?

Apk, that didn't do it.
yes, it did the same thing beforehand. Except takng out the battery solved the problem once.

Get it exchanged ASAP. This is a defect with the USB port. Has NOTHING to do with software. I was outside of my 14 day return and Sprint made me send it to Samsung to get fixed. $7 jig and two weeks later it was fixed.

With my tech background I would say check the charging port. Could be a metal shaving or *gasp* corrosion!

Shouldn't matter. The phone has a one year warranty from Samsung. I bought my wife an Epic on craigslist last year and had it repaired under warranty.

Yup. I had the same problem. I think it is related to the USB port (from reading a few SGS2 threads). I took it to the Sprint Store and they said the USB port looks good. They reset it and it still acted that way. However, 2 hours later the problem is gone. They ordered me a replacement so I'm still going to take it because who knows why the problem starts. I did have Calk's rom and also have the battering monitoring widget by 3C and I had cleared the battery stats multiple times prior to the symptoms starting. Just proving as many clues as possible...

What do you mean by reset?

Funny I see you have this problem (not really funny) because I noticed the same thing last night and just figured it was Rom related.

It sucks... can you give more details about the reset process? Soft reset?

and bump...

no dice

I had the same problem.
The red light was on all the time, only went out when I got a text. If I pulled the battery the phone would show like it was charging as soon as I put it back in. It would show the battery animation on the screen not plugged in.
After a battery pull the phone would also not boot using the power button, had to boot to recovery and boot from there.
Took it to sprint, they gave me a new battery. Solved the problem only until phone was plugged in to charge. Then started all over again.
Turned out to be a problem with the USB port and they ordered me a replacement.

got it fixed! looks like the pcb on the port was sitting too close to the lower edge of the phone. pushed it up gently and now it seems to be working. thanks for the direction, nivron.
my other concern is that battery life sucks ass. drains really quick (at the rate of ~6%/hr!). again, running calk 2.7 + ics theme. also, taking out the battery seems to reduce the life 20%. what's the deal...

Hmm, now the USB cable needs to be at a certain angle for the phone to charge. Is there any way a Sprint store could furnish a replacement for me?

[Q] Help!!!!! Screen going on and off idk what to do!!!

first of all thank you for taking the time to read through this.
Yesterday I woke up and reached over to check my LG G3. I had left it charging overnight as I usually do and while the phone was still plugged in and I tried to go through my notifications, the screen flickered and went off. I was puzzled cause the phone was fully charged and the screen has no cracks and barely any scratches. I was trying to restart it and the LED light started flashing as I heard a notification sound.... I proceeded to take out the battery hoping thatd help out and nothing.
I thought my LCD took a **** on me but I tried to restart the phone once more about an hour later and then the LG logo came on shinny as ever. Then the AT&T logo, I thought all was well but then the screen flickered again and went off. A few moments later I started to hear more notification sounds and I saw the LED light start blinking.... everything in the phone works except the screen.
I changed my sim card to an old blackberry knock off so I wouldnt be cut off from the world while I went to work and when I came home I tried to play with it once more and the phone started working normally! As I was playing with it I raised the brightness and the screen started to flicker again but did not shut off. I immediately brought down the brightness and the phone seemed to work normally I then tried to open the camera and the screen went off completely same happened when I tried to refresh an app. What could this be? the battery? currently I the screen doesnt stay on for more than 10 seconds and does not work at all when plugged in to charge
Also in the last couple of weeks I was experiencing overheating but I assumed it was because of the rise in temperatures and the fact I spend most of my day outside and Im constantly using my phone. I am also guilty of using my phone while charging.
Any input you may have is going to be helpful. I need to figure this out as I use my phone to work more efficiently.
Thank you in advance!

I am having the same issue. I'm going to contact LG about this on Monday.

got answer ?

Yeah, they changed the entire display and said that the error could come from a defect battery. So i bought a new one and hoped for the best.
I still had the error today. I will try installing another rom so I can be sure it isn't the software.
Or else LG will be getting it again.

Well, they got it again... Twice. They changed the LCD panel and the mainboard. It seems that the latter fixed it. I got it back on Saturday and haven't had any problems since then.
Fingers crossed

I forgot about this post but I used my warranty last year and got a new phone or refurbished. They didn't tell me. Here I am a year later with the new phone and the same problem came back. The only thing that seems to work is baking the main board at 350 for 10 minutes and letting it cool down in the oven for 30 yet the problem comes back. After a week or so. I'm convinced the overheating of the phone is he culprit

G4 Intl. Charging issues

Hey guys,
first of - sorry if this is oftopic.
I notice heavy charging issues on my g4 intl. The phone just won't charge probably.
I'm running on the latest cyanogenmod nightly, everything else works fine.
Cyanogen says "slow charging" even when I plug in the original cable, or a quick charge wallplug. With all micro USB cables everything is fine for a week or two, but after that everything repeats again.
It seems like the phone cuts down the input power to 300 milli amps or so, while "charging" the battery percentage is going down sometimes, too.
When the phone is off and plugged in, the charging is slow too.
But sometimes everything is fine for a charge or two.
Does anyone have the same issue or have a solution?
Greetings from germany

Okay I found some guys talking about this here, but is there any final solution for this?

It happens to me too, stock ROM, cm13, aosp, no difference.
I have tried changing USB cable (only cable) and device begin charging normally again.
I don't think it's something software related..
But if you have already tried with another charger and problem is still there..

I'm really frustrated. I don't know what is happening to my g4, since 2 month's I noticed heavy red screen ghosting, too. The phone was already repaired once from lg, there the problem was that it won't boot up anymore.. Next time I won't buy lg..

I got problems with display too..
Both lateral sides are brighter than the rest of the screen.
Especially with dark images it is absolutely horrible.
Will never ever buy LG anymore.

same problem here with the ghosting and the super slow charge some times battery goes down even while plugged to original charger, had a G2 before this, love the phone was almost flawless, this one I had it for almost a year now, piece of **** full of problems, now after the lates OTA the unlocking is retardedly slow, I double tap for unlocking the screen wakes up but dimmed and unresponsive and after a second it fully wakes up, I'm so frustrated with this piece of ****, the only good thing is the camera. Btw regarding the slow charging problem, I tried with different batteries and chargers and same results (I'm fully stock, no root no nothing)

my problem is that sometimes it just doesn't charge at all the led blinks and i wake up for 0%

SM-P605 cannot charge

Greetings, I have a bit of an issue with my tablet and it's most likely a hardware one.
About two days ago I had my tablet completely discharged and I put it on the charger. I saw the battery and lightning screen and left it for about a day.
Then yesterday I wanted to watch a movie on it and so I reached for it and all it had was a black screen. I thought that it must have charged up completely, so I pulled it out of the charger and started it up.
It then went as far as the Samsung logo and 20-30 seconds afterwards it shut down. I thought that maybe my ROM became faulty or smth and tried to boot into TWRP. Same thing.
Booting into the Bootloader worked but at one point the screen started rapidly changing its brightness. And it again turned off after a couple of seconds.
I tried this several times, connecting it to the wall charger or my laptop but every time it turned on for only a couple of seconds and now it has completely died off. No matter with which cable, charger or power source I try to charge it, it doesn't light up at all. Power button and combinations with volume buttons don't do anything.
A bit of info about the device: It's about 2 years old running the latest LineageOS. Roughly 1 year ago it suffered a drop and the screen got cracked. I ended up buying a spare screen from China and gave it to a hardware specialist to install it. (Samsung doesn't really have representatives near me, so that was the easiest option) Ever since then the speakers have always been a lot quieter and worse-quality but everything else worked fine.
I believe that somehow the charging circuit fried itself and now the battery has died off. Is that even possible? I haven't charged it with any unknown wall chargers or anything that could fry it. Can someone please help me fix this problem since I have no idea where to start?
Thanks in advance...

You might want take a look to this topic of mine. Not exactly the same problem but the resolution might apply to yours as well.

Thanks for the suggestion, but your tablet can at least boot. Mine can't, which is the issue and it doesn't charge at all when off.

That's why I pointed you to open it and resettle all the cables, as I did. The problem is different but the solution might be the same...

Mi 5s Sudden Death?

Hello everybody,
so yesterday my two year old Mi 5s died completely after crashing 3 times in about 30 Minutes.
After the first crash I noticed that the battery status had suddenly dropped from ~60% to 33%.
Now, after 3 crashes, the Phone seems to be completely dead. No Bootscreen, no status LED when charging.
Also, the phone doesn't even get slightly warmer when plugged into a charger.
It's literally just a brick at this point.
Because of the suspicious battery drop after the first crash, I suspect that the battery just died.
Fortunately I ordered a replacement already, about 1.5 weeks ago.
My question is this:
Would you suggest waiting for the new battery (which should arrive in 2-3 weeks) and hoping everything works with a new battery?
Or would you rather buy a new phone?
Even if you are not an expert, I would still appreciate your opinion.
In case anyone wonders, I was using LOS15 with latest(-ish) firmware and magisk, though I suppose none of that matters for the issue at hand.
UPDATE: After removing the battery; plugging in charger; attatching battery and repeated plugging in and out I now have a blinking red LED.
Victory? Not sure .. I still can't boot but at least something is working?

this thread sounds similar to your situation... https://forum.xda-developers.com/mi-5s/how-to/blinking-red-led-death-t3743795
worth a shot before your new battery arrives. and since you already ordered your battery its best to wait for it and install on your phone, while putting your sim in a backup phone. if it still doesn't work then buying a new phone would be the best option.

Thank you for your reply! I tried the methods described in the thread you linked and updated the OP.

I had a similar problem 2 days ago. I changed the battery, now it works again.

Same thing in my case - new battery helped.

Thanks a lot! I revived my old Nexus 5 (what a great phone!!!) and will stick with that until the battery replacement arrives.

New battery fixed the phone, it's working normally again (and lasts much longer ?).
