[Q] Nexus 5 and wireless charging.

Hi Guys,
I have a nexus 5 and I noticed that my LG WCP-300 continue to charge even when the battery is full.
The charger works fine with my Nexus 4, it stops charging when the battery reaches 100% capacity but not with the N5.
I'm wondering will it affect the battery if I keep it on even tho the device says "Charged" ?
Thanks in advance

Interesting. My Nexus 5 just arrived and I'll be curious to see how my LG WCP-700 charger handles charging the Nexus 5 when i get off work.

I think they finally fixed the wireless charging. My N4 would stop then drain down then start charging again. I never knew if it would be fully charged when I took it off the charger in the morning. I'm certain the battery will not overcharge.

Off topic, what is the use of wireless charging other than not using a wire to charge ?

That is pretty much it, it just save you plugging the wire.

Apart from the convenience of just putting down your phone to charge it will save your USB port from damage so if you need to fastboot for repair / warranty / general flashing you know it will be in good condition if the time comes. My galaxy nexus USB port broke, plugged in the charger and noticed it wasn't charging after a while and plugged the plug to see smoke come out the port and the phone was very hot! It may have caught fire if left. So now that phone has a dead battery, luckily its removable so could be charged separately with out the phone. The screen would turn on and drain battery too. I'd fully recommend getting one if you can, I intend on getting one in the future.

I aslo have the WCP-300 with my Nexus 5. I am experiencing the same thing.
I wonder why they changed the charging. I know my Energizer Qi charger also does this because the charging light always stays lit blue.

Wireless charging on Energizer
I have the energizer charging pad and noticed the same. My Nexus 4 would stop charging and if it fell back to 98% would charge again. The Nexus 5 just stays charging at 100% and I have read that it can damage the battery overcharging like that. Can someone confirm that for sure?

nothing on this?

Not unique to the charger

Just for the sake of clarification. The same thing occurs with the Nexus 5 using the Panasonic QE-TM101 which (as above) worked flawlessly with the Nexus 4. So it appears to be the phone (not the charger). And in spite of people assuring us that this won't damage the phone (battery), I can't help but think that the heat can't be good for the battery and if it wasn't "actually" charging after it hit that 100%, then what's generating the heat (it has to be actively charging to create that heat). I plan to do some controlled tests to see if the same problem occurs with my OWL (Qi compatible but not Qi certified) chargers, and see if the charger is cycling on and off during the charge period or staying in charge mode. But every time I've awoke in the morning the Panasonic charger has actually been charging (charge light on) with the handset very warm.
I'm afraid that if it's not cycling then over the long haul the battery (or possibly the phone) may suffer ill effects due to the consistent heat.

[Q] Nokia Wireless charger continues charging after battery is full

I bought a Nokia wireless charger from ATT online store.
It works on my nexus 5, but when the phone is full charged the LED light on the charger is still solid on (on means charging, and blinking means done). However I go to Setting->battery, and it shows battery is full.
My question is which one is right?
-Wireless charger is still charging the phone.
-The system shows battery is full, so the phone won't be charged. But since the charger is Nokia, so it doesn't know my Nexus 5 battery is full.
Thanks in advance

I believe there phone will stop charging the battery buy the charger won't know so it'll keep going. The phone has the circuitry to prevent damage to the phone.

I purchased (2) tylt wireless chargers from kickstarter a while back and I planned to keep the N5 cradled most of the time.
Unfortunately while the chargers work great they also heat the battery to 110 F while charging as compared to around 80 F with a straight USB charger. I'm afraid this heat will eventually kill the battery. Since the battery isn't easily replaceable I've decided to abandon the wireless chargers.
The batteries and the whole device stays hot after its charged and until I pull it off the charger. I didn't notice whether the charge light actually went out on the charger itself after the charge was completed. If I'm brave or (dumb) enough to try it again I'll report back.
Anyone having better luck with the stock wireless charger or other wireless chargers like the Nokia?

I purchased the same Nokia wireless charging pad, and, despite the LED not turning off on the pad, the battery DOES stop charging once it is full.
This can be observed through a battery monitoring app like Battery Widget Reborn. If you look at the battery graph at any point after the battery hits 100%, and before you remove it from the charging pad, you'll notice an even 2 or 3 percent drop and rise at regular intervals. This is the trickle charge mechanism. Once the battery is full, it stops charging, Once the battery drops down to a certain percentage, the charge resumes, and the cycle repeats itself until you take the phone off of the charging pad.

Same here with another brand on wireless charging pad, I think it's normal

Are you not concern with premature battery wear considering now it's not user replaceable? Heat is supposedly not good for battery life.

This really explained me what happens. Thanks !!!

Battery Health

I'm not sure which one has an issue, it could be my 1+ cable, the phone's battery, or the 1+ AC charger.
Basically, my 1+ cable no longer charges my phone when connected to the 1+ AC Charger. But works fine when using my powerbank. So I am assuming that my 1+ cable is defective. So swap cables, now using my Nexus 5 Cable and it charges my phone using the 1+ AC charger, but its very slow. I checked on batter monitor its only maxing out upto 1.7A then reaches 80% charge, it went down to only less than 1A (800mah). Is that normal? Or the 1+ ac charger is defective?
I also noticed that previously when using the 1+ cable and 1+ ac charger, my phone charges up so fast. It can finish charging in 1.5 hours. But not its 3-4 hours to fully charge.
So I'm confused now which is which or maybe the phone's battery is defective? Hope someone can shed light onto my issue. Thanks! :good:

Qi Charging Issue; Turns On and Off at 100% Charge

Do any of you have an issue where the phone screen turns on and off (and beeps) when it reaches 100% charged using a Qi charger? I am using the official Samsung wireless back cover with a Nokia Qi charging pad. When the phone reaches Charged, it will turn the screen on, then it'll say Charging Wirelessly 100%, then it'll turn the screen off and start charging... and the cycle repeats every 20 second or so. Anyone else?

I think it is standard glitch on all Samsung phones. The same thing happened with my old Note II, and it happening with my Note IV too. I have to shift phone maybe 1" off center so it would not make that noise.

Yes, I turn off notification and system sounds at night while charging with Tasker, and I use Gentle Alarm to display a dim clock so I don't get the screen flashing.

Thanks for the quick reply! Now I know that it isn't just my phone or charger, I can rest easier and just let it be (mostly will just take it off stand when charged).

My Note 4 is using S-View cover with wireless receiver built in + OEM Samsung Wireless Charger Pad (the big one) & I never experience your problem.
It only shows "Charged" once then fall asleep again until I turn it on.

this is correct if the note 4 is not properly centered ona single coil charger. upgrade to a 3 coil or center the charger coils with the base.
it takes place because the signal to cut off the charger at 100% is not properly received by the charger base so the charger keeps charging. the note 4 assumes the sginal sent will cut off charging and goes into a no charge state. then when current keeps flowing through the coils it wakes up and issues a no charge command again...which is again lost because the coils are too far apart. and the cycle repeats.
solution is to switch to a 3 coil charger or align the coils with each other.

Is there a way to find out how many coils in my charging pad?

Phone keeps waking up while charging

When I'm charging the phone it keeps lighting the screen when the battery is under 100% (like when you plug the phone to the charger), charges up to 100% again and lights again the screen. It's pretty annoying specially during night. Does anybody had the same issue? It only happens when charging with usb-c charger, not with the wireless charger. I'm using EU rom 10.2 Stable.
