Yes plenty has been written and posted online by experts on wireless charging. Premature battery wear is exactly one of the reasons phone makers like this option, it guarantees a shorter life span for your phone so that you're more likely to upgrade sooner. This is averted to some extent by using removable batteries. Which is another reason they pair wireless charging with a non replaceable battery. That's another reason why this is a consumer oriented phone, if you choose wireless charging swapping the battery is inexpensive.

But as far as wireless charging itself, It's pretty simple... if it takes longer to charge wirelessly, which it does, and if heat increases during charging, which it does, then there is no way you aren't diminishing the battery at a faster rate than keeping the phone in a charging state for shorter periods with conventional charging. Like I said if you are a battery swapper it doesn't matter.

But this same thing applies to Quick Charging. That creates more heat too. Which is why Quick Charge and wireless charging should not be done often or for long periods (like charging from empty to 100%) unless you don't mind less screen on time and faster battery wear. If you don't like those things wireless and quick charging should be done (infrequently) with battery swapping if you do use one or other or both.

So I'm guessing the backwards-ass LG either say "have wireless charging support, or a dual SIM model", right?
[LG V20 Guides, News, & Discussion] @rbiter:
Wireless charging the DAC when listening? Lol. Nonetheless I will believe it when I see it. Probably means a plastic back but oh well. Don't care for metal anyways. Metal frame like note4 is OK but give me plastic. All this metal and glass are premium is garbage and make phone more shatter prone. LG did a nice job with the v20 though they should've used sapphire of gg4 for the camera lens. And if they do indeed release wireless charging I hope it is not thicker and is fairly flush with back. My current back isn't perfect but nothing to complain about.

LG back track record for wireless back is a fail, and usually available in only a few market for a good few months, then it's none existances.

I think that the LG representative that said that there will be wireless charging is clueless. I think that those pins in the rear are some sort of shielding or antenna extension. I bet that they are all connected if tested with a multimeter.

Please keep the post on topic.

I have this case to use a wireless receiver as a temporary solution, the case has a slot for a credit card or a smartcard, but using it a wireless charging looks good without the bulge.
[LG V20 Guides, News, & Discussion] SgtBarrett:
The G3, G4, G5 and V10 all have wireless charging built into the factory battery covers. The V20 is the first LG phone that will require you to buy an LG case that replaces your battery cover with the new case, and voila, the new case has wireless charging built in.

---------- Post added at 05:21 PM ---------- Previous post was at 05:15 PM ----------

This "repairability" that LG builds and engineers into their phones is why I will never consider anything else. Even the earphone jack snaps in and out for replacement. Heck, the V20, though it didn't include wireless charging in the case, includes the pins above the battery to attach an aftermarket wireless battery cover. The LG company is VERY forward thinking in a way that does not make sense to the masses, but makes perfect sense to those of us that have a gram of knowledge and understanding about technology and common sense.
[LG V20 Guides, News, & Discussion] roosta:
I like how they call this a " wireless receiver\charger" yet you require a physical cable for it to work. This is piss weak after market stuff... Where are the receiver sections you tape inside your phone, or a back cover that connects direct to the pins? Otherwise there's no point in these gimmicks.. As you are already using a cable?!
[LG V20 Guides, News, & Discussion] kms108:
The V20 has been confirmed to have this, but not proven yet, if this is the truth, it makes no difference to what the G3, G4 and V10 is, which is also market depended, not all market has this wireless feature, but all require the battery cover to have a coil antenna.
[LG V20 Guides, News, & Discussion] Pick_A_Name:
The problem is the metal back of the V20. The tape kind won't charge through the metal. Until they provide s wireless back cover, we're stuck with this crap ( which I'm not using).
[LG V20 Guides, News, & Discussion] esqueue:
The LG G4 required a different back cover to get wireless charging. I know that my black leather back cover only had NFC. The LG Quick Circle case that I purchased had both NFC and wireless charging.

LG is known for supplying the lowest end accessories with their devices. LG G4 came with a standard slow charger instead of a QC 2.0 and the V20 comes with a USB 2.0 cable and QC 1.0 charger instead of a USB 3.0 Cable and a QC 3.0 charger.
[LG V20 Guides, News, & Discussion] roosta:
Is it common for LG to release a new flagship and practically no accessories to go with it, 2 months on? Seems like poor marketing strategy to me. People buy cases and screen protectors almost immediately to protect their phones, not wait 3 months...

[LG V20 Guides, News, & Discussion] KOLIOSIS:
My money's on the LG Customer Care rep who corresponded w/the OP was misinformed.

I was hopeful,but,not optimistic,as the conventional contacts near the battery are MIA & not a peep out of LG on their website,in the V20 phone description/specs,or,in the accessory section.

One member here in the V20 section mentioned seeing TV advertisements promoting it in Soutk Korea,but,nothing of it has been spotted elsewhere,or on YouTube,which leads me to come to this conclusion:

OEM LG Wireless Charging support is an elusive unicorn.

You can use your phone while wireless charging

You can use your phone while wireless charging. I use my Samsung Note 5 that way frequently. I have a wireless cradle for the car and another one for the desk. Necessary because I broke the USB charger port. And because the battery life SUCKS! I'm looking into replacing it with the V20. It would be really nice to have a replaceable battery AND wireless for me because I'm an extreme user.
[LG V20 Guides, News, & Discussion] emdroidle:
The V10 back cover shipped with V10s did not have support for wireless charging. You had to purchase a replacement back to get wireless charging (for $60). I'm expecting the V20 to be the same, just LG is being rather slow in getting their back out to the masses.

Seems some models of the V20 have fewer pins on the back, I merely see 7 extras on mine. This is still plenty for wireless charging (which only needs 2).

There is also a second thread on this topic. Really need to get one closed and have everything on the other.
[LG V20 Guides, News, & Discussion] tickertapes:
What we need is a non metallic aftermarket back cover so we can add a QI coil internally and still retain the a free USB port.

Has anyone on here got a close up photo of the motherboard QI contacts for the T-Mobile variant? There is a good chance that the SMT pads are on the non QI variants of the board in which case it may be possible to add the gold spring contacts.

Where there's a will there's a way!!!
[LG V20 Guides, News, & Discussion] railshot:
We probably don't even need an aftermarket cover. The coil can be taped to the battery/phone and covered with any of the existing cases. However, there are a bunch of contacts on the back (10 or so). I have no idea how to determine the 2 correct ones without risk to the phone.
[LG V20 Guides, News, & Discussion] evo4g63t:
I honestly can't see the appeal of "wireless" aka pad charging, it's slow and is it really that difficult to plug in a phone especially with USB c?

No offense intended I just don't see the appeal personally especially with no fast charge. I am curious why so many like it though.
[LG V20 Guides, News, & Discussion] railshot:
I have a bedside cradle at home, at the office and a wireless charging car holder. The appeal of the wireless charging is that I pretty much never have to plug in the phone to charge. I don't need to think about charging because my phone rarely drops below 50%.
[LG V20 Guides, News, & Discussion] wtharp2:
It's simple convenience. And you also haven't considered how wireless charging saves wear and tear on the USB port.
[LG V20 Guides, News, & Discussion] emdroidle:
I kind of flip-flop on this. All the movable/stressed portions of the USB-C port are on the cable end of the connector, so the phone receptacle is supposed to have near zero wear. Even then the cable end is supposed to last 10,000 insertions/removals so the connector should be pretty darn long-lasting. In theory (famous last words).

The best reason for wireless charging I've run into is it means you can have the phone charging somewhere and if it rings you simply grab it without worrying about attached wires. Whereas if you're charging via cable you need to be careful picking it up.
[LG V20 Guides, News, & Discussion] cwis:
Wireless charging is slower, so I dont understand what the big deal is. Who cares about a wire??:confused:
[LG V20 Guides, News, & Discussion] Teknoshamn:
Just discovered this thread, and upon reading it I took my back cover off of my Sprint variant that I bought just yesterday. Sure enough, the pins are present. I have a QI charging pad, so I popped it on, but neither the phone nor the pad appear to respond, unlike my Note 4 (may it R. I. P.), so others are like right about it using the competing charging standard.
[LG V20 Guides, News, & Discussion] ChazzMatt:
it's not either/or. You can have Qi wireless charging for when you are not holding your phone. You can plug your phone in (I have lots of 10ft cords) for when you want to hold the phone.

Too many people think like you, that you are FORCED to use Qi wireless. You are not. But I will not buy a phone without that feature. The convenience is amazing.

---------- Post added at 01:22 PM ---------- Previous post was at 01:17 PM ----------

Exactly. Qi wireless is meant to be used in addition to plugging in sometimes. I have tilt charging pads all over the house for both mine and my wife's phones. Set it on the charger, walk away. Ready to go somewhere, pick it up, walk away. Easy to see notifications due to the angle.

I have QuickCharge 2.0 also, so I plug if I have to, but Qi is very convenient. Most hardware failure comes from stress on the charging port -- plug, unplug, plug, unplug a thousand times.

Once I used it with my previous phone, the LG Nexus 5 I was hooked. Have it on my Moto XT1225, and whatever replaces this phone will also have wireless charging.

---------- Post added at 01:27 PM ---------- Previous post was at 01:22 PM ----------

Because the convenience is great. Like having a remote control for your TV. Why can't you just go over to the TV and change the channel manually? Turn up or turn down the volume manually? Why do you NEED a remote control?

(Yes, at one time remote controls were newfangled things people debated whether there was a need for.)

And yet once you use a remote control, of course you understand the appeal. ;)
[LG V20 Guides, News, & Discussion] sanjsrik:
Okay, I have a stupid question, i have a T-Mobile version of this device and went looking for the "contacts" you're talking about and don't know what you mean. I had a wireless charging back for a previous device and was looking for something similar on this when you posted this. Don't see it, can you take a picture and point out which contacts you're talking about?
[LG V20 Guides, News, & Discussion] emdroidle:
If you'd looked earlier on this thread, specifically right here is such a picture. I need to check mine. I didn't count quite that many of them. Perhaps later ones lose some of those pins or else some variants have fewer.
[LG V20 Guides, News, & Discussion] sanjsrik:
Thank you for clarifying.
[LG V20 Guides, News, & Discussion] evo4g63t:
I have NEVER had a port on a device fail from wear and tear, especially not USB let alone 3.5mm (which would be far more likely to wear out just on the way it works, i.e. Cords get caught on stuff and pulls the cord out from the device). I am talking decades of use. Worst thing I've had is the cord connection becomes lose and I can't really move the phone while plugged in but this was from the connector on the cord rather than the connector on the device.

Furthermore USB c seems to be much better built than micro USB, the connection feels much more solid.

That being said I just read here that you can use wireless charging while using the phone? How does this work? This changes my opinion considerably since I was under the impression that "wireless" charging requires the phone to be on a pad.
[LG V20 Guides, News, & Discussion] The_Keeper86:
I got one of those Chgeek wireless receivers which seems to work well. It claims to fast charge but I just get normal slow charging. It also seems to only want to charge if my screen is on. Anyone else have any experience with this particular receiver?

Also I'm using my fast charge adapter that came with my phone. Even tried my old Note 5 fast charge adapter with same result. And yes my wireless charger supports fast charge thanks!

Shame this phone doesn't have native wireless charging so lame.
[LG V20 Guides, News, & Discussion] dartinbout:
I loved the fast wireless charging from my Note 7 and Galaxy S7E. It was super convenient at work to just plop it on the silly flying saucer I got from Samsung. LG is offering Qi charging with the G6 but......it's not even fast wireless charging! This combined with the lack of a DAC for the US market means I won't be trading my V20 for a while. Personally I don't ever expect LG to offer wireless charging for the V20 at this late date in the product cycle. You can get a flat add on that works but it to is a slow version and it occupies the USB-C port under a suitable case. This DAC has changed my relationship with mobile devices permanently. It is now my chief criteria for assessing any new phone.
[LG V20 Guides, News, & Discussion] tickertapes:
My concern is the SMT solder joints on the motherboard. Sometimes the joints break and require resolder re-soldering, if the pads come away from the motherboard, he phone can trashed.

Wireless is definitely the way to go IMHO.
[LG V20 Guides, News, & Discussion] The_Keeper86:
So strange and ridiculous that LG hasn't released a wireless qi back replacement yet like they did with the v10. It's as if they're going backwards.
[LG V20 Guides, News, & Discussion] @rbiter:
Yes. Weird. You would think they would try to make some money off accessories. I am up to 6 batteries. Makes me wonder if the v30 will be sealed.
[LG V20 Guides, News, & Discussion] The_Keeper86:
Exactly. I bought a wireless receiver it worked but my god did it charge so damn slow. I hear the G6 will have wireless charging but not fast wireless charging lol so lame.
[LG V20 Guides, News, & Discussion] The_Keeper86:
It wouldn't be so bad if we could also use our wall chargers when needed. Shame these occupy the USB port :/
[LG V20 Guides, News, & Discussion] rubiicon59:
Having just got a V20 H990ds I can clarify the pins for the NFC antenna are the two located immediately in board of the Volume + button.

The other 7 pins around the perimeter that correspond with silver rectangles on the rear cover are for grounding purposes. The silver rectangles are where the anodised finish has been removed to facilitate a direct electrical contact between the pins and the rear cover. This keeps the cover at zero potential / voltage.

On this V20 variant there are no pins relevant to a wireless charging coil.
[LG V20 Guides, News, & Discussion] tickertapes:
Are there any SMT solder pads on the main board for the two Qi contacts?
[LG V20 Guides, News, & Discussion] The_Keeper86:
Pretty ****ty LG never bothered to release a wireless charging back cover when the v10 got one. I doubt they'll even release one this far into the devices life either. I'm using one of those charging things that plug into the USB port and hide it behind my case. After used my wall charger in nearly two months. Still would be nice to use it when I need to though.
[LG V20 Guides, News, & Discussion] emdroidle:
Those rectangles aren't silver, they're white. Looks more like a coating of titanium white or other non-conductive coating, rather than the silver color of exposed aluminum.

Even if the areas on the back cover were bare conductive aluminum, this would not interfere with the role of being used for non-contact charging. Shorting two contacts used for Qi/PMA would merely prevent them from being used for that purpose, not damage them. When inactive Qi/PMA receivers do not place any charge on their coils, so it would be the same as not being in proximity to a charger.
[LG V20 Guides, News, & Discussion] rubiicon59:
Hmmm

Ok then :rolleyes:

(I've no idea what you're on about BTW)
[LG V20 Guides, News, & Discussion] The_Keeper86:
Does anyone know of a way to also be able to use the wall adapter as well? I tried looking for a small USB C splitter to allow me to use the wireless adapter but be able to use the second USB port on the splitter (if one exist) for charging if I had to but had no luck in finding one small enough.
[LG V20 Guides, News, & Discussion] fiver5:
I searched high and low a few months back when considering a Pixel, I found nothing.

I no longer have easy access to a 3D printer, seriously considering going out and buying one just so I can make my own damn case with wireless charging and usb charging passthrough. This is ridiculous.
[LG V20 Guides, News, & Discussion] The_Keeper86:
Good luck with that. I know the closest thing I could find were USB C hubs and I definitely don't want a hub hanging out of my phone all the time.

I still can't believe there was an official wireless charging back cover for the v10 but not this phone. That cover must not have sold much or something.
[LG V20 Guides, News, & Discussion] frettd:
No back but this might work...

I, too, have been looking for a charging back but I found Qi charger plates on Amazon. I can't post the link, but search for lg+v20+qi+wireless+charging+back. It looks like they stick on the back of the cover on the outside. Not particularly attractive, but should still charge under a thin phone cover. You'd have to make sure the cable would clear the case, too. I'm tempted to try one because the price is pretty low.
[LG V20 Guides, News, & Discussion] emdroidle:
That revealed a bunch of chargers which plug into the USB-C port and include their own Qi chip, nothing specifically adapted to a V20. Such things should work, except all the visible ones obstructed the USB-C and wouldn't allow pass-through of anything else (either normal USB or MyDP).

Hi everyone.

I've gone weeks looking through the internet trying to find a solution to my problem.

Basically, the screen of my phone is cracked. The touchscreen function of the phone no longer works but the phone still lights up when charged.

I did not leave USB debugging on in the phone.

I do not have any sort of app that lets me control the phone remotely on the phone.

I can still access the recovery mode of the phone.

I tried connecting a special cable to the phone to connect it to a mouse / keyboard and both did not work.

I am just trying to recover some data and pictures on the phone.

Is there some way to turn USB debugging on so I can use something like Vysor to open the phone? Or any other way to get the data inside?
