Lg G2 battery connector issue?
I just ordered a new battery for my G2 and everything went fine in my reassembly but the phone would not show any signs of powering on or charging. After QUADRUPLE checking I've found the it will only turn on if the battery connector is pushed so the left side of the connector is disconnected.Weird. I've experimented with ways to keep the connector in place while I reattach the back cover and casing but it is always pushed down. If the phone is already on while the battery connector is pushed down then it will show it is charging but will not charge AT ALL. Any ideas what I can do?

I have an iMate Jam with a damaged LCD that I have disassembled to put a new LCD into.
I've been pretty careful with dismantling and reassembling, but after the last time I put it back together, it won't start up anymore, even after hard resets.
Also, the red LED won't come on when I plug in the USB cable, if the battery is in, but will if the battery is removed or the battery cover is off.
Does this mean I've somehow fried the battery or the charging protection diode?
Any other ideas about what might be going on here and how I can remedy it?
hi i have a nexus 4 12 months . i bought a battery from ebay 5 months ago .before 1 month my main battery was inflate a little and the back housing of the phone cant close proper.i swaped the battery .the new battery charge only to 16% and then discharge with the charger on .when i plug out the charger the battery discharge fast to 4% and shut down.
i bought a 3rd battery from ebay
i charge my phone closed 30min now and the phone dont have power to turn on.
the charger is the official with the official cable from lg
I do something wrong??
sorry for poor english.
It could be the charging flex that is broken. But these batteries from ebay could easily be bad copies which don't work. I know spareslg.com sell genuine parts if you want to be sure.
I have a similar problem. The battery was draining really fast and not charging when plugged in, so I got a new battery. It still didn't charge so I tried a wireless charger. That does work but it will not charge via USB. When plugged in, the icon changes to the charging icon but it doesn't say that it is actually charging. In the battery status screen it says "not charging."
Would my next step to be to try to replace the USB port? I've cleaned it out as best as I can with a toothpick and used some contact cleaner as well.
I think the problem is with the way you replace your old battery
Are you sure you replace it correctly ?
I had previously successfully replaced the screen after I dropped and shattered the phone. To do that, I successfully disassembled and reassembled the phone with no issues. I ensured all connections were tight when I replaced the battery and disassembled again tonight to check all the connections and the battery still will not charge -- both the old and new battery. I do not believe at this point that the battery is the problem.
So there's lots of questions about bad battery life but haven't found my issue in searches - altho I suspect my issue is a factor for many to some degree.
N4 took a 4' to drop to concrete. Screen cracked. Replaced screen w/no problems. Ran fine for a while on stock 4.4.4. Lollipop comes OTA practically zero day and since the N4 isn't my primary phone I upgrade to play around. Shortly after 5.0, the battery drains and shuts the phone off. I charge it overnight, pull it off, battery is dead, phone shuts down. Will stay on and operate fine on wireless charger but powers down if not connected. Pop off the back again to make sure battery connector is snug and reassemble. Now I've got red light of death. Get Google logo and can boot to recovery options but it just cycles. Disassemble again and ultimately find that the battery pins from the mainboard and their little black housing have come off at some point. Try to solder it back on but there's chips on the back side and there's just no room to get the solder on and pins reconnected. Not w/my skills anyway.
My main question is, has anyone successfully reconnected that annoying mofo? Thinking about skipping the connectors and just soldering wire straight from the battery to the board. I don't see anything in that connector that would be a problem if absent, but any warnings I should know about? Other workarounds?
This is not mission critical, just principle/spite.
Repaired?

So were you ever able to get the connector solder back on? I think mine break because it was to hot when I was removing the battery. My nexus 4 shutdown on me, my battery was expanded. I was wondering why my screen was being pushed out. I wonder if Android 5.0.1 is causing phone to run to hot. Never did this with Android 4.4.4. Hope the connector can be fixed. Maybe I take it to a solder shop.

Not yet. I pulled the connector back off and cleaned everything up. I found that even very small gauge solder is too sloppy for the 4 small connections. Not to mention there's chips on the back side so you can't linger too long with heat. So my plan is to try again with some conductive ink and/or gel. If that doesn't work I'm just going to use wires to bridge the battery right to the board. Haven't had time to work on it but I'll follow up here when I do.
Did you get a replacement battery? Lithium batteries can swell because of overcharging. There are definitely more than a few N4 owners who had the same issue. A replacement battery won't solve that problem but it could be more tolerant of it, for a while - and depending on if it was "user error" or a fault in the phone's overcharging protection circuitry. Don't go to the trouble of having someone solder the connector back on with the old battery.
I had my N7 screen broken and the bezel damaged and i have had it lying around for about a year now. I finally replaced the screen and bezel on my tablet but it won't turn on any more. Looking for some info on how to troubleshoot what's the issue. What I've done so far is:
Checked that the battery seems to be fine and charged. Using a multi-meter on the battery connector gives a 4.15 V reading. The connector is properly connected (I get the same 4.15 V on the places where the battery connector socket meets the motherboard).
Changed the ribbon cable after finding out that the battery seems to not be at fault. This had no effect.
Tried to put back the old broken screen and bezel to see if maybe the new ones are damaged. Last time i used the tablet with the still broken screen it was able to power on and boot. Now after the fix using the old screen and bezel didn't work.
I have tried to hold the power button with or without holding the volume down button for various amounts of time with no effect.
As i see it now there are a couple of equally plausible things that could have gone wrong.
I have both damaged the new and old ribbon cable while changing the screens.
There is still something wrong with the power circuitry despite battery being at healthy 4.15 V.
The new bezel and screen that came from e-bay were damaged on arrival.
I have damaged something else while changing the screen.
Any ideas on how to troubleshoot any of this?

Now some 24h later i'm getting 3.8 V. Which according to this http://forum.xda-developers.com/showthread.php?t=2195070 corresponds to battery being at about 60%. Could it be that the tablet is powering on but the screen stays off due to a damaged LCD ribbon cable? Is N7 in general able to boot up with a damaged LCD ribbon cable?
Hi,
Please can anyone tell me whether the little connector on the vibration motor is supposed to be soldered to the motherboard or does it just touch at a certain place?
I've already posted another thread about having replaced the battery but it doesn't seem to charge.
Without going into details all over again, a local repair shop replaced the charging port last week - my phone was returned in seemingly working order but they had assured me a bulging battery was OK. I charged my phone but the battery was draining quickly, which was what led me to research a bit more and discovered how dangerous it can be so I ordered a new one.
In the process of fitting the new battery, I discovered half the screws in my phone missing, no copper tape, plus there is no black rubber cover over the charging port & vibration motor as is shown on the guide for replacing the battery on the fixit.com website.
So I'm wondering if the small square 'connecctor' (?) part of the vibration motor ought to be soldered to the motherboard or is it just normally held in place by the black rubber cover? In my phone now, the 'connector' doesn't stay touching motherboard so I'm not sure if this would affect the phone and stop it from functioning or would it just mean the vibration wouldn't work?
Would this affect whether the battery could charge or not?
(Incidentally, I discovered that the the battery connector was upside down compared to the pictures in the ifixit.com guide (the red wire was nearest to the battery instead of the black wire being nearest) so I was hopeful that by correcting it to match the picture, I would have solved the problem but unfortunately, it didn't make any difference. When I connect a wall charger, the screen just flashes and when I connect it to my laptop, it just gets a blinking white led but nothing more. It seems strange to me that it wouldn't make a difference - is it like a usb-c cable in that it can go either way round?)
The battery seller asked for photos of the new battery in my phone and has now offered to replace it - is this likely to make a difference or is the vibration motor not being attached to the motherboard the cause of the problem?
I'll be so grateful for some help.
