[Q] Is it the Battery or is it something else?

Hi there.
My Mother has a One V which she is really happy about. But recently she says that it has been draining the battery so fast. At first i didnt really believe it (you know old people and tech), and asked if she had charged it correctly. She then told me that the charging process was also quite strange.. She had plugged it in one night, and the phone displayed that it was charging.. Then 8 hours after, in the morning it had only charged 2% ! This doesnt happen all the time, but only some times.
Now she has given it to me and hope that i can fix it. At first im just going to factory reset it, even though i dont think that is the problem. But i have noticed that what she is telling me is true to some extend. I have had the phone sitting on the table all night. No simcard and no nothing.. It had only used about 5%, but as soon as i began using it, to take backup and prepare for the reset oh boy.. It uses 1% in merely seconds! Approx 26 seconds per 1%!
I think this is rather strange and im unsure if the battery is the problem.. Do you guys have any ideas ?

Oh and i have to say that the phone is running newest stock software. It has never been rooted or anything like that.

Well, the charger port is probably bad. My first htc one m8 and my droid incredible 2 both have weak ports on them from the factory. Send it in for warranty and say nothing < about a possible bad charging port if it still has warranty. And, if nothing Less try a brand new charger, and see if that one works and if it's loose when it's plugged in. If it Is loose with new charger it's a bad charger port.

Yeah this confuses me as well. It happens once every few months. The battery drains really fast and charging is extremely slow. The first time this happened my One V dropped from 100% to 27% in 20 minutes! And just like it randomly happens it randomly goes; battery consumption goes back to normal after a day or two.
A possible reason is the charger and USB cable that is used. My cable is worn out so that might be why charging is slow but it doesn't explain why the battery drains so fast even when the phone is disconnected from the charger. So the only reasonable explanation would be some hardware problems in the battery pack.
But this is all just me guessing... I don't know for sure.

It could be the charger port. I tried cleansing it with a toothpick (heard dust could be the problem), but the problem persists

The problem here is that it happens every second time or so the phone is charged at the moment. But i have bought a new battery and will try and change it. Ill write here how it goes and if there is a improvement, so that you know where the problem relies if you are thinking about doing the same.

Same problem here. Every few months the battery drops from > 50% to 2% or so. This happens within some minutes and my phone gets really hot.
But normaly I use it with a 2 amp charger and I think this happens more often if I use chargers with 1 amp.
Edit: This happened for me with every rom I used.

I changed the battery two days ago, and i can already feel a huge improvement.. 8 hours ago i took it out from the charger. Data and Bluetooth has been on all day. Been browsing a little, and sent som SMS and stuff like that.. 65% now.
The conclusion must be that in my case at least, it was a battery hardware fault.

I'm also thinking about replacing my battery, was replacing it easy?

Yes it was actually pretty easy. Although i have done it on my One S too, and that was even easier.
Some recommendations: Get your self a repair tool kit before you start. Everything has been so much easier for me after i got that. It is all the money worth it . This is what i got http://www.ebay.co.uk/itm/261399617620?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT <- They ship worldwide.
The battery i brought : http://www.ebay.co.uk/itm/321303229844?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
First i took the plate off at the bottom of the phone (the one where there behind is sim card and sd card). Unscrewed all six screws. Once done you can take all the plastic off the large plastic part (the one below the simcard and sd card when inserted, and covering everything behind the outer cover). This part is also taped/glued, but should not be a problem to get off.
After you have taken that off, use a pry tool to pry the plate open around the camera lens and flash (beware that this plate is also taped together. Unscrew the last screw behind.
Now comes the tricky part. You need another more solid pry tool to pry the lcd/board out from the front. Use the pry tool in between the screen and the cover of the phone, and all the way around. The LCD and board needs to come out from the phones front.
After that the battery becomes visible. There is nothing special to getting the plug out for it as far as i can remember and should just be pulled towards the battery to get it out. Battery is glue to the inside of the phone, but using the solid pry tool you should be able to get it out. If you order the battery i linked to, it comes with new 3M tape.
Heres a video showing it pretty good i think:

Aah so it was the battery pack after all!! Interesting to know.
Glad it worked out for you and thanks for the battery replacement links.
My One V is retired but since the battery is cheap I will buy one and replace it just in case I ever need the phone as backup.

I HAVE FOUND A SOLUTION FOR THE LG G4 BOOTLOOP ISSUE *Story & Tutorial*

Basically what happened, was on Friday, my phone got stuck in a boot loop. It would get to the "Optimizing Apps" screen and shut off again. Other people may just get to the Verizon screen, or even just the LG screen. I looked it up and found that it was a major issue affecting many people, so I just filed for a warranty and received my new phone today. Well, on Saturday night LinusTechTips, a popular tech YouTube channel(You should really check them out, they are great), released a video on how they fixed a dead Graphics Card and PCI-E SSD by heating them up past the melting point of solder and then testing them. For them, it only worked on the GPU. As I was packing up my seemingly dead phone to ship back to LG TODAY, i decided to give it one more shot. I disassembled the device to the point where I could take out the logic board. I took the logic board and wrapped it in one layer of parchment paper and two layers of tinfoil, shiny side facing in(FYI tinfoil has two sides, shiny and matte). I then placed this package into a barbecue. I turned on the left and middle burners and left the package with my logic board inside on the right side to the grill so it wasn't receiving direct heat. After 10 minutes, I took it out, re-assembled my phone and it booted. I was able to get all of my pictures off of it. This has only been confirmed to work on my phone, but seeing as this SAME issue is affecting thousands of people, It's definitely worth a shot. If you are going to use an oven, PLEASE, make sure it's above 385 degrees Fahrenheit and that you don't plan on using that oven for food ever again, this may release some toxic chemicals etc. I plan on using my grill again, so I just made sure to leave the grill open for 24 hours and I'm going to clean it before I use it next. If you have any questions let me know!
P.S. My LG G4 was the Verizon model.

I highly recommend doing this ONLY if you have no other option. Remember that heating a logic board to high temperatures can release toxic fumes. Don't use an oven you use for food preparation! Toxic fumes can leave residue in the oven and will be re-released upon reheating over many cycles!
Assuming LG's press release regarding the issue is correct and it is really a loose contact, this "fix" could actually work. Of course, only if the loose connection is a soldered connection. Though, it's controversial. You have to remember that the melting point for SMD solder is around ~350°C, or 662°F. So 358°F, or 181°C, is not nearly enough to actually re-solder a loose connection. My guess is that the loose solder point is only expanding due to the heat. There is no real reconnect. It might only be a matter of time until it also breaks. If you could locate the actual loose connection you could really re-solder it and have it fixed permanently.
I've done this on many many devices, including graphics cards, smartphone logic boards, PC mainboards etc. It only works if a soldered connection has a crack small enough that heat expansion is enough to gain reconnection. If there is a loose contact on the PCB or the "crack" in the solder is too big, it does not work. Also, if you really have a dead chip, this trick also won't (always) work.

I read a similar story on reddit. The guy put his main board in the oven, reassembled it, and the phone started working. The last update I read was 3 days later, still working.

I fixed mine temporarily by heating up the emmc chip using solder hot air gun. It seems to be just the emmc chips connection.
Failed again after a fortnight when the phone got too hot. The connection seems to break when the g4 gets hot.
One option to try is to boot the phone inside a freezer. I found that worked too.
Pretty poor quality control on lg's part.
I'm going to try again and see if I can fix permanently.

Worked for me too
I have a LG G4 H815 with serial number starting with 507. It died yesterday night. The bootloop escalated quickly to full death. Even the freezer trick did not work.
I followed the OP instructions. I heated up the grill to ~250 degrees Celsius and cooked the motherboard for 10 minutes.
Magically the phone has been working for a couple of hours since and I have been able to backup files to the external SC card.
I wonder how much more will it work.
Thank you for help OP!!!
Word of advice to other LG G4 users. Backup your phone regularly. Use an external SD card. Set the camera to save images and videos to the SD card. At least at doom day you will have them saved.
Cheers

any more info on this? Looks like my phone bit it the other day, no boot...just dead...
I'm going to take her apart to see if I can find a bad solder, luckily I still had my G2 lying around.

NFN, I sent mine back to LG US in Texas for a full warranty repair. 10 days RT, no cost at all, shipping included.

No unfortunately. I managed to overcook it and it stopped booting altogether

Do you have the address and info Re your communication w/ lg

What is the beginning of your phone's serial number?

Hi bro kindly tell is it worth to install custom rom kernal with root to prevent the cpu to clock high speed so it will not go into bootloop? My is also 2 years old thanks

250 degrees F for 6 minutes and brought the phone back to life. We'll see how long it lasts.
Actually it worked on BOTH G4s I have. I first just went dead and I bought a used one for $100 on eBay and it worked fine until the bootloop showed up.

LG G3 D855 Screen flickers and fade to darkness

Hi and thank you for checking my thread
I have a problem with my G3 as described in the tittle, I did the Paper trick I saw on YouTube but sadly it didn't work
After a while I found out that placing a piece cut from Credit card under the CPU might work and I did , but one week later I had the same problem, likely I can just click sleep button and it returns to normal
After these many problems I decided to give up on it and sell it, but I need a permanent Fix so I don't get involved in Cheating
Also , does replacing motherboard will fix the issue ?
Does G4 Worth it now ? I know about bootloop problem

Probably is a bad motherboard
When my G3 finally died (digitizer went bad), I just replaced it with a used G4 for $150. That was like 6 months ago. The phone has been phenomenal. I know there is many who say that every G4 will bootloop eventually, but I really don't see how thats possible if you just browse google for the issue. Yeah, a lot of people had the problem, but if everyone did you wouldn't see the G4 still being sold at a ton of outlets, and you would see hundreds of links to the issue. I think there was a large batch of them that were bad... and they got past QC, but the vast majority of them are probably fine.

Yea, i saw "1 month/year after" Reviews on youtube and no one montion the bootloop issue, people ask them in comments and they reply that the phone works normal with no issues
Thank you for replying dude appreciate it

I was skeptical at first, but by baking the motherboard in the oven did the trick for me. It has been a couple of hours now an no flickering, no black screen and no troubles. And i know i'm asking for Murphy to come and bite my as*, but as a little trick, i'd like to suggest before putting the mobo in the oven to try something: i have an old Akasa X4 cpu cooler which has metal fins which are removable. I took one of those things and cut a square a little bit smaller than the power IC to the right of the SoC and then cut another one the exact same size then stacked the two one on top of each other, making sure to not short any capacitor around the IC and then put the metal shield back, making sure to put pressure on the IC. Then preheated the oven at roughly 180 degrees celsius, then put the motherboard SoC face up into the preheated oven on three balls of aluminium foil, one at the bottom near the micro usb, and the others to balance the motherboard, like a BMW Isetta, and put the timer for 10 minutes. After these nervous 10 minutes, I took out the mobo and let it to cool at room temperature for ~30 minutes. And voila, now it works. I do hope that it is going to last, and i will be very careful with this phone, unlike the previous owner. Seriously, how can you put a freaking button (small one, from a shirt) between the SoC and the mid-frame? Crazy. And that's why i got it for ~8000 JPY (about 70 bucks).

I had a similar problem for about two months. I tried the paper thing over the camera sensor and I felt like it helped some but the problem still continued. The screen would just slowly go dark with vertical lines running through it. All apps would still work in the background while this was happening. I could boot to TWRP and this problem never happened while in TWRP which was odd. Seemed like if it was a screen issues or hardware malfunction it would happen all the time. That's when I decided to just flash back to stock. I was thinking about getting the S8 anyways so what the hell. I flashed to stock 10B and took every single OTA. Took all night but I've been running stock for over a day now and the issue has not replicated itself one time since reverting back to stock. I was on RR Nougat and Fulmics when it happened prior. Has to be a root or Rom issue?

Just wondering if your G3 is still functioning without the issue.
It really feels like a hardware issue but as you pointed out it didn't happen in TWRP... but like many, I encounter the issue when the phone gets a bit warm (>35C), so maybe TWRP and your stock android is not as hot as RR Nougat? Then again, I'm on MM when this happened...
Update: Actually the flicker n fade happened to me in TWRP while I was backing up. The temperature read about 60C.

I had bigger problems with my g3 and they started as follows
Problem 1. camera not being detected and crashing. 2. Reboot once a while which got worse over time. 3. Bluetooth sketchy and WiFi not connecting. 4. Sd card being ejected and mounted constantly. 5. Mobile data stopped working.
Solution: baked it in the oven 10min with cpu side up at 185c removed to cool 4 30min. Problems gone for the meantime.

This morning at work my D852 died with the exact same screen fades to black and would only stay on for at most like 10 seconds and would only come on again after the processor cooled enough. I came across this youtube video.
https://www.youtube.com/watch?v=UF1s4RCZAvc
Since I didn't have any copper foil tape, I substituted with Aluminum foil tape and placed the tape in the same places as detailed in the video. (copper works better than aluminum for heat dispersal)
My phone is now back to normal and hasn't shown any issues with the past 5 hours since I applied the fix.
UPDATE: My phone has worked perfectly for several days now until I turned on the GPS from Cell Tower to High Accuracy and it immediately started to die again. Once it cooled down I was able to get to the settings screen to turn off GPS and it went back to functioning like normal

How to fix
I tried the paper trick and it did not work. No need to replace the motherboard or the phone. The issue is just a bad connection between the motherboard to the LCD display.. Probably due to dirt (in my case, I found that quite a few places in my motherboard had corrosion buildup). Here is the fix...
1. Remove battery cover and Unscrew The back plastic from the base of the phone to get to the motherboard.
2. Disconnect all the connectors from the motherboard.
3. Scan the motherboard for anything unusual. (My motherboard had corrosion on several different places).
5. Clean any dirt or corrosion with lint-free cloth. (I didn't have one so I had to use a Q-tip).
*if needed, Dip the cloth in rubbing alcohol to assist in cleaning. make sure that the cloth is JUST BARELY Damp and not dripping, otherwise you will risk water-damaging the phone. If you use rubbing alcohol, make sure that you dry the spot right after you wipe it.
6. Once you have cleaned the motherboard, check the base of the phone and clean any dirt from here also.
7. Replace the motherboard, re-connect the connections, screw on the back, and put the battery cover back on.
Viola! Mine has been working like new for 4 days so far with no issues...

So a permanent fix is a new motherboard or a new screen?

Fixing a dead LG G3 (D855) with a hair dryer

Hello people of the internet and most likely LG G3 users. Yesterday my LG G3 D855 died right when I was about to watch some good hentai. I’ve been having screen flickering for ages in the YouTube app and as of late the screen also started to fade to black from the corners, random reboots were also quite common. Android became unresponsive for a couple of seconds and then the screen when completely black in a split second. Tried a lot of things after that: removed the battery countless times, changed with an old battery, charged it for hours at the time (battery wouldn’t get hot so no charging), connected to my desktop. No Android, no TWRP, no bootloader, nothing could make my G3 do anything. I was convinced it became a paperweight. After that I proceeded to disassemble the phone. Disconnected all the ribbon cables of the cameras and the display etc and put them back in firmly. That did do anything. HOWEVER I remembered when I was wasting time reading toxic XDA comments and stuff that someone mentioned baking the device to restore connections between the motherboard and the SOC, or something like that. So I did some research and even though something as stupid as putting it in the oven actually seem to work for people. Mum wouldn’t let me put it in the oven so I made my own way of resurrecting my G3. This is what I did to get it back working:
I’M NOT RESPONSIBLE IN ANY WAY IF THIS GOES WRONG AFTER TRYING THIS. IT IS 100% YOUR CHOICE TO DO THIS OR NOT.
Requirements:
DISSEMBLING
LG G3
Screwdriver small enough to remove the G3 screws
Plastic prying tool (old credit card, solid thin plastic will do also)
Good light source
REVIVING PROCESS
Hair Dryer that can get a fair bit hot
The grill of an oven
Stopwatch
A floor that can withstand heat
A place that can be ventilated in case of toxic fumes (nothing happened for me)
Safety goggles (I didn’t have and so didn’t use)
Electrical fire extinguisher (I didn’t have and so didn’t use)
STEPS FOR MAKING AN UNDEAD PHONE:
1. Remove battery, SIM card, SD card.
2. Proceed to disassembling the phone to the state where you only have the motherboard. I used these guides:
https://www.ifixit.com/Teardown/LG+G3+D855+Teardown/42288
And
https://www.youtube.com/watch?v=sNymIdIXTyI
3. Place the oven grill on a surface that can withstand heat and then gently place your LG G3 motherboard on it.
4. The heating process:
1.
Turn on the hair dryer and start to focus the heat on the part of the motherboard that is facing towards you when you take it out. So not the part where you see the SOC. See image. Hold the hair dryer close to the motherboard (5 cm space or so) and do this for 10 minutes.
2.
Let it cool down for 5 minutes and turn it around.
3.
Proceed to heat the SOC for 15 minutes and let it cool down fully for a minimum of 15 minutes.
4.
But it back together, hope that luck is on you side and that it will turn on.
NOTE: First boot went all the way till android boot screen when it crashed with screen flicker. I removed the battery and waited a minute or two and tried it again and it has been working ever since yesterday night. This is probably not a long-term solution so I’d suggest just using this to get your data off you phone and moving on to another device as fast a possible.

EDIT: Like I said before use this method only if you find putting it in the oven is to risky. My phone has now stopped working. This really is a temporary fix for if you just want to backup you remaining data.

i have used G3 for last 3 years and its was still good phone in market ..ok to the point
i have 3 G3 and one i bought for experiments and i put in Oven and guess what it show some sparks and burn from botton pat of the board so dont ut in oven it can burn and ic on board .. heating through hair dyer is safe i think for noobs... thanks

Totaly dead N5X back to life after baking motherboard

For a while ago I bought an defect Nexus 5X on Ebay to use as spare parts, I needed a camera.
Just for fun I have tried to get the phone working. It has had some life signals but since some time been totally dead. No lamp while trying to charge and no start.
Today I thought why not? I bake the motherboard in the oven, did so. After 200 degrees Celsius, maybe a little more, 10 minutes in the oven and time for cooling down I manage to get the phone start. Now it's running LOS without problem.
Maybe it's not working tomorrow after being cooled down totally , we will see.

Keep us informed

Still working today, being switched off during night it starts and boots as normal today.
One thing I didn't mention is that before I baked the motherboard in the oven I did take away the two metal shields/covers on the board, one on each side. Just to snap them off and it worked to just put them back again after baking.

Today after a while the phone freeze and switch it self of, so this did not work, no harm done but worth a try
