Yes, aware of that. I noticed this, btw

Hadn't noticed previously that it actually says on the box to use a 2A charger!

Just saying that even without changing the charger (yet - I've a 2A one on order from Amazon), just changing back to stock kernel has made a big improvement for me such that I'm no longer seeing it "charge once" then stop charging altogether (as was happening previously). Obv if you're already on stock, that ain't gonna happen for you

EDIT

Graph came from Battery History - it's newish in Google Play. Found it yesterday. Pretty basic atm but does what we need. Only takes hourly logs of battery level, but that's good enough https://play.google.com/store/apps/details?id=me.jack.batteryhistory
[Nexus 4 Accessories] WibblyW:
I use Llama to announce the state of the battery (charged/charging/discharging). I noticed the topping up via a qi charger is cyclic based on minutes not hours. I just wonder what, if anything, this does to battery service life/longevity in the long term (vs. the 'continuous make up' charge it gets when on a wired charger)

The heat won't be good, but it's all about compromise and convenience i guess. http://batteryuniversity.com/learn/article/charging_without_wires
[Nexus 4 Accessories] Restorer:
Weirdest thing here: having been charging to 100% and then switching off completely, a couple of days ago it started charging to 100% - and then staying topped up. I have changed nothing and am completely stock ROM, kernel and supplied N4 charger.
[Nexus 4 Accessories] thfreedumb:
If you read the topic there is discussion on the charger not typing off consistently with stock charger. Use a 2a charger. The stock kernel seems to be better at typing off too
[Nexus 4 Accessories] Restorer:
Did you read what I wrote :confused:?
[Nexus 4 Accessories] WibblyW:
As has been said, results with the N4 charger are inconsistent.

The spec seems to suggest you need a 2A charger. Using an under spec charger (as far as the Metrans is concerned) is this likely to give unpredictable results. If the Metrans is trying to pull more than 1A at some point when using a 1A charger, the input voltage from the charger will start to collapse and it's quite possible the Metrans firmware would crash at least in part, so all bets are off as far as how it would continue to operate until it's reset.
[Nexus 4 Accessories] Restorer:
That seems to make sense - though if sometimes it turns off and other times it stays topping up it makes no difference to me personally. However I am a bit worried that the "topping up" seems to be being achieved by the unit remaining on at 100% charge (blue light continued to flash as far as I can make out).

Interestingly though, when using the 2A charger from my tablet the Metrans unit turned itself off at 100% and did not restart. Maybe I will go back to that tomorrow and see what happens.
[Nexus 4 Accessories] Jhonb:
I have a different charger (Zens) but with mine, it will discharge down to about 96% and then charge up. I have a similar program and with mine, I see it run the cycle about 3 times a night. So when I get up in the AM, the phone will be anywhere from 96% to 100% depending on where it is in the cycle. If you try leave yours on the charger longer, or try running some program while it is charging that will use some battery, you can see if yours cycles as well.
[Nexus 4 Accessories] Hessi93:
I received my charger today and everything is working fine. Well, the phone seems to get pretty hot, around 45-46*C, but i hope that's OK..

Skickat från min Nexus 4
[Nexus 4 Accessories] thfreedumb:
i'd move it around to find a better sweet spot and i'm usually running around 36c. I remember reading that under 48c seems to be okay (nexus 4 will throttle above 48c) and the phone with shut off at 60? I'm not positive and feel free to correct me as i'd like to have correct information myself.
[Nexus 4 Accessories] The Unnamed Time Lord:
Will this work with HW_rev10 Nexus 4's? Or will there still be issues with the device charging?

Also will it work with my Seidio Convert N4 case on?
[Nexus 4 Accessories] Blazing angel:
Is this site reliable?
[Nexus 4 Accessories] thfreedumb:
If you read more than 2 replies in here you'd realize most people have received their devices and have no complaints.

So yes, it is reliable.

And most cases seem to work with this. Right now i'm in the process of determining whether its runs hotter with a case than naked.
[Nexus 4 Accessories] furyoflight1029:
Just purchased one, hopefully it'd work with my thick case.
[Nexus 4 Accessories] Blazing angel:
If you use paypal, does the site automatically make an account for you? I tried making one after buying the charger, but it says I already have one.
[Nexus 4 Accessories] furyoflight1029:
Add the item to cart, then itll prompt you to register an account if you dont already have one. after that you just pay with paypal the same way you purchase anything on ebay, that's all.

Any suggestions to stop the nexus 4 from slipping off the charger?

Gesendet von meinem Nexus 4 mit Tapatalk 4
[Nexus 4 Accessories] thesoupthief:
Chewing gum? Blu-Tak? Superglue? (ok, maybe not superglue)

Mine seems to balance ok in what I think is the sweet spot - if I move it too far south of that it falls off.

Admittedly, mine is on a stable surface and doesn't get knocked / nudged. If this is the problem you're having why not just cut a disc from one of those non-slip rubber mats (available in 1 Euro shops over here - probably get them on dx.com too) and stick it on the top of your charger - they're only 1-2mm thick so shouldn't interfere w charging.

And that brings me to my question for you guys (which would probably solve the above problem too), can anyone suggest an app to give some guidance as to charge rate for wireless charging?

I've found a number of different widgets that give some indication as to the charge rate, but many seem to consider only wired charging and all give info visually, either in a graph or with digits.

Would be really neat to have an app that beeps not just when charging begins but maybe gives a different chirrup when the charge rate reaches a certain level, indicating that the device is in the sweet spot

Anyone got any recommendations?

Maybe I need to get busy with Tasker for this
[Nexus 4 Accessories] WibblyW:
Llama (like a kind of lightweight free Tasker) will spot wireless charging and charge level, but not charge rate. I use it announce charging/charged/discharging when those conditions happen.

It would be good to be more easily be able to find the sweet spot based on charging rate, but would I suspect not be easy. The best charge rate will be different depending on how full the battery is (because charge rate reduces anyway as the battery charges), so what would be needed is some kind of automatic scale on a widget that would show the last x samples so you could set it the maximum at any one time.

If you look at the qi spec, chargers can be capable of doing this automatically by (a) moving their coil physically or (b) doing clever stuff with multiple coils. I think there have been one or two examples of each (certainly a, not sure about b?). But low cost chargers like the today's Metrans are simple devices with one static coil inside.

One option might be to craft a plastic "tray" into which the phone drops neatly with the Metrans fixed underneath in the right position. so the phone would always be placed optimally relative to the Metrans. Would have to be done nicely not to destroy the neatness of the Metrans. Maybe start by modifying a N4 case so the N4 could just rest in it rather than clip in it? Or modify an in-car holder? Or look at the box your N4 came in - there's a cardboard tray the N4 can sit in. Maybe just fix the Metrans under that in the right position ;) !?

[Nexus 4 Accessories] thesoupthief:
Interesting - I've noticed the battery level seems to drop more quickly over the time I've been using wireless charging, but this coincides with a few other changes (shifting from 4.2.2 with custom firmware and kernel to stock 4.3) so I hadn't partic put it down to anything sinister - hadn't gone looking at wakelocks. Unhelpfully I had a play with cm10.2 last night so wiped my battery stats / wakelock history etc but I'll have a look at this over the next bit.
[Nexus 4 Accessories] WibblyW:
By all accounts heat is bad for lithium polymer batteries and the stress of elevated temperatures WILL reduce the service life of the battery to some extent. But in the real world it's a trade off between convenience and what we can't change about LG's design of the phone. Plenty of advice here and talk of trade-offs:

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

and

http://batteryuniversity.com/learn/article/charging_without_wires

I seem recall some press about LG's design/spec of the N4 battery to increase longevity at elevated temperatures, but can't find it now.

At the end of the day, if you still have your phone when the battery capacity falls to unacceptable levels and whenever that is, changing the battery in an N4 would seem to be one of easier pieces of surgery that can be performed on it. So expect to DIY or for it not to be too pricey to get someone else to do it for you...

Few things:

1. Re: ccab's point above.

Based on one night's experience, I haven't been able to repoduce that "not going into deep sleep after wireless charging" problem, with a good chunk of deep sleep over the past couple of hours, however within those couple of hours there has been about 10 minutes of a kernel wakelock that sounds suspitious - "PowerManagerService.Wakelocks". Also "msm_hsic_host", but I understand that's not specific to wireless charging - can be fixed by reverting to an earlier radio apparently but I'll hold fire before meddling. I'll keep a weather eye on both. (Nexus 4, Stock 4.3 Rom - sideloaded JWR66V - and stock kernel with that, rooted; checked this with Better Battery Stats).

2. Re: Battery temperature while on wireless charging.

Mine wavered between 26 and 40 degrees C (briefly getting to 40, but spending most of the time in the low 30s) last night while charging from 12% to 100%. Once it reached 100% (around 2am) it hovered at 100% til I took it off the charger at 7am, with charge kicking in and switching off every now and then - every 20 mins or so? During this time the temperature was fairly stable between 25 and 31 degrees. The charger was fairly cool to the touch this morning. (Checked these temperatures with Battery Logger).

Forgot to thank WibblyW for that Battery University link the other week - v informative

Back to point 1. - Just checked Wakelocks again - that PowerManagerService.Wakelocks thingy is ongoing and has prevented deep sleep for the past while. Odd that it didn't kick in for the first few hours of the phone being off power. Will add an edit to this post later if it ceases and allows deep sleep again.

EDIT - yeah, so a few hours later I've checked and found that the phone had begun deep sleep subsequently - currently PowerManagerService.WakeLocks have been active for 15.8% of the time since taking the phone off charge this morning. Not a critical problem, but not ideal either if it's not serving a useful purpose

What is everyones charge rate? My office is in a pretty weak signal area but this seems slow...

I have the galaxy note 2 samsung charger (5v, 2a) and a 6 foot micro usb cable from monoprice (the slim version). My charge rate seems to never go above 400mA. I expected the charger to get at least 650mA. I am using battery monitor widget to get my data. I tend to place the phone on the lower 2/3 of the nexus 4 (i believe the induction coils are there?)

Any idea on how to improve the charge rate? Is it better to use a thicker and shorter micro usb cable (overall higher quality)?

I didn't think that this would be limited to usb speeds (<500mA). I enabled the fast charge with franco kernel and will see if this makes a difference in the long run. not much yet...

Ordered mine 31 Jul, shipped 2 Aug, arrived 18 Aug (UK). I paid for insurance but not tracking and got a tracking number anyway. Not that it was much use, it just says "In Transit" then the package suddenly turns up weeks later.

The QI charger works perfectly with an HP Touchpad mains adaptor but I also ordered these http://www.ahappydeal.com/product-38281.html despite saying they are 2a chargers, they DO NOT work.

Very happy with the wireless charger though.
[Nexus 4 Accessories] salem_christ:
I'd start with a shorter, thicker USB cable. 6 ft is a very long usb cable. If you need your charger a long way from where a power outlet is, get a mains power extension cord, not a longer usb cable, and plug the charger into that closer to where you are.
[Nexus 4 Accessories] khodos:
hey guys,

I received the charger yesterday and, after using it for the first time, I have to say that i'm also having problems with the phone being kept awake by the "android OS" service. Any workaround?

Regarding the charger, is way too small and makes uncomfortable using the phone when on the dock. It's even a bit tricky to position the phone so it starts charging, as someone already said in this thread.
[Nexus 4 Accessories] picodot:
Mine shipped on Aug. 1st and I received it about 2 weeks later.

I'm using the stock wall charger and cable that came with the phone. (I don't think this is ideal since the wall charger is 1A and the Qi charger prefers a 2A input, but it probably just results in a slower charging rate).

It works great for me. I set the phone down before bed and it's charged by morning. I don't have any problems with finding a good 'spot" for charging.. I usually place it such that the charger is near the bottom.

For $21 shipped, you can't beat it - this is 1/3 of the price of the orb that Google sells directly. I'm considering buying another one to use while at work, but between this and a car charger, I'm pretty well covered.
[Nexus 4 Accessories] creaturemachine:
I'm having a problem with this thing where it'll charge the phone, but sometime after it's full the charger freezes, the blue light stays on and it no longer delivers power to the phone. The blue light remains on even after I remove the phone and the charger is unresponsive until I cycle the power. Meanwhile the phone battery is draining, leaving it in the same state as when I put it down at night.

tried to charge last night with stock charger:

from BBS i can see that the battery was charged to 99% (so seems ok) but after that the phone didn't go to deep sleep so after 4 hours dropped to 85%.

after tanking off the phone from charger it started to deep sleep again.... will try to test with a 2A charger and report it.

i am on stock rom with faux kernel...
[Nexus 4 Accessories] WibblyW:
Wouldn't this be expected? Phone stays awake when actually on a qi charger as maybe the phone's processor is used to manage charging from the phone side of things...
[Nexus 4 Accessories] beren:
i'd expect the phone to stay awake while it's charging, after this the charger should turn off so the phone can go to sleep...no?

i mean, i like the charger stops after reaching the full battery so it doesn't circle between 95-100% like others do, but it should also become "invisible" to mobile so it won't stay awake draining the battery.
[Nexus 4 Accessories] thfreedumb:
I see people are repeating the same issues that have been discussed in this thread. If you are using the stock 1.2a charger, you need to replace it with a 2a charger to get it to top off the charge so its at 95-100 when you wake up the next day. The 1.2a charger will top off and then shut off, from my experience and others on this thread.

Any luck tracking your package?

Just pinging you guys to see how much luck you've had tracking your package. From what I read from the thread, consensus is, not much...

I ordered my charger on 8/20/2013. I got an email saying they received my order and I should get a tracking number. After one week of nothing, I submitted a ticket asking for the tracking number. A few hours later, I received a reply and a tracking number. Unfortunately, when I tried tracking it, it says the item was delivered a year ago to someone in Pennsylvania (I'm in California).

I asked them to double-check and resend the correct tracking number. Ugh! I guess I should just stop stressing and wait. Got spoiled by Amazon Prime 2 day shipping :p
[Nexus 4 Accessories] anirudh412:
I feel your pain about the waiting. Patience, it seems, is not one of our strong suits :D Forget the tracking number. That thing is useless. It took a little over 3 weeks to get to me. Having ordered plenty of things from China in the past, I know it takes anywhere between 2-4 weeks for delivery.

battery monitor widget pro. Don't be expecting miracles as this is wireless charging. Most I get is like ~800 and this is according the the widget. I would check with that before saying it only gets 500 to be sure.

[Nexus 4 Accessories] thfreedumb:
this might be silly but ill ask anyway. Do you put the wireless charger on the bottom 1/3 of the phone? thats the sweet spot. Have you tried it without a case? Do you have another 2a charger laying around? I found that the samsung chargers work best. in specific, the note 2 white charger you can get on amazon. If you have a custom kernel, make sure you have the rapid charge on computer usb set. It's possible your phone thinks its a computer because 500mA is the usb charge speed from a computer. if you go into the battery information screen it'll tell you how its charging. its that #*#*4636*#*# thing (i think i got it right but google to make sure). you might need to plug it into the microusb port to check the usb cable.

And I've found that battery monitor widget pro works much better than the free version. Not saying you should drop the cash as i can't be confident it'll help.

[Nexus 4 Accessories] furyoflight1029:
If anyone from Canada living in Scarborough and interested in this charger, I'll sell mine for $30 which just arrived today after waiting for more than 3 weeks. I don't really like it, the built quality is very nice but it charges slower than with the usb cable. Although this is really convenient, but I'm not really the lazy type of person. I don't know if it's because I'm using stock N4 charger on it, that's causing it to charge slower. However, I don't have the patient to buy and wait for a 2A charger to be shipped here.

Got mine in 3 weeks

Correction and update: Actually, I got mine in 2 weeks. Also, left the phone on the charger using an old 1A HTC plug and amazonbasics cable. Phone was fully charged in the morning and not warm at all. Awesome!

FWIW, here's a recap of my experience

I never got a valid tracking number.

The number I got was someone else's that was delivered about a year ago.

The company really does respond to support requests within 24 hours.

Mine didn't ship from China. It was from Fiji and from their parent company name.

Mine required a signature so I had to go to the post office, show ID and sign which was a pain.

Charger seems to work fine using a Amazon Basic microusb cable and an old HTC plug.

Charged from 50 to 90% in about an hour.

Charger and phone got pretty warm.

Bought another $16 generic charger from Amazon. From China as well but it came in 2 weeks and had a valid tracking number. Tracking number was pretty much worthless but at least I got one.

Anyway, so far I've been happy but still not ready to trust keeping the phone on the charger over night. I plan on bringing the other $16 charger to work so I can monitor the heat.
[Nexus 4 Accessories] r1nstang:
mine works fine. kinda picky on placement though. im considering tearing it apart and "installing" it underneath my end table or coffee table and see if it will charge my phone thru the thin plywood
[Nexus 4 Accessories] yvrRome:
Been using mine for a few weeks now with a 2.1amp charger. Works perfect for me. I leave my N4 on the charger overnight and it doesn't get warm. Stops charging when it reaches 100% where the flashing LED turns off. I think it starts charging again when it goes down to 97% where the LED starts flashing again.

Seems to charge fast for me although I've never really timed it. I don't have issues with placement, I just keep it on the bottom half of the phone since I read that's where the charging element is and its always detected.

I'm really very satisfied with it especially since the price is what I'm willing to pay for a wireless charger.
[Nexus 4 Accessories] waterman50:
One question I have is whether it is ok to let it charge on the Qi and use the N4/N7 at the same time. Particularly, I wonder if streaming
