[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.

[Q] Keeps charging at 100%

Hello,
When I charge my Nexus 5, the battery icon keeps on showing it is charging even so the battery is at 100%. Also my USB charger (not the one LG one) indicates that the device is still charging. Is this normal ? Would this damage the battery ?
Thanks

It's normal.

Thanks ! (But i just find this weird as I expected a device to stop at 100%)

I understand what you're saying but it's not a charging icon, it's a connected to power icon. If you were to use something like the dashclock extension it would show that it actually stopped charging once it reached 100%

Thanks for the reply.
The thing is that I have this charger http://www.portablepowersupplies.co.uk/portapow-quad-usb-mains-charger/) and the LED indicates charging (albeit I did not measure the current ).

Nice unit!
Are you connected to WiFi while charging? I had the really bad battery drain issue while connected to WiFi after the 4.4.2 update. I lost about 30% of charge after 4ish hours while connected. Currently I'm at 92% after 3 hours.
The WiFi battery drain could be causing your phone to not fully charge or at the very least make your charger THINK it's not fully charged. No harm should come of it either way but it's always best to pull your phone off the charger once it gets to 99-100%

Thanks for the reply. I had Wifi activated; it might be the reason.

My wireless charger LED didn't shut off when my N5 was charged in a powered off state. Usually it does once the battery is full.
That said, I don't think it's over-charging the battery, as that would be really bad

Don't worry about it. This isn't the 2000s where constant charging is an issue.

Just tried with the Wifi Off. My USB charger then indicates that the unit is not charging.
Thanks for the replies and great help.

Don't worry about it. The charger isn't the thing that determines how charging is handled, it's all done on the phone side. The phone knows how to take and stop taking power.
In the case of the Nexus 5, it most-likely stops charging the battery but continues using the power from the charger to actually power the unit (thereby no-longer using the battery to run the device, but not charging it any longer).

Anyone else having wireless charging issues?

Wireless charging seems flaky at best. Sometimes, it works like a champ. Sometimes, my phone will stop charging, start charging, stop charging, start charging, etc. until I get annoyed, pick it up, and put it back on the charger. I left it on the charger overnight and found it at 87% this morning. I don't know if it wasn't charging properly that whole time, or if it got to 100% and then just stopped charging. Any tips on this? Anyone else having similar issues?
FYI - this is the Samsung charging pad and the phone with no case or anything on it.

No issues here. Work flawlessly

I'm also having the issue with wireless charging starting and stopping. My charging pad, however is an ebay qi pad. Seems very position dependent on both of the pads I was using successfully with my S3.
The behavior is that it will start charging, then 10 seconds to a minute later stop. Then start....then stop...

S6
I have the sony charging pad and I've noticed my S6 stops charging when I get any kind of notification...

No issues here

you shall use 2A chargers to be effective.

I do. I have an official Samsung 2A charger with an official Samsung USB cable attached to an official Samsung wireless charger.

I haven't paid attention to it throughout the day, but I did notice that if I place my phone on the wireless charger it seems to charge to 100% and then it will stop charging. I know a few nights ago the samsung puck was green when I fell asleep but in the morning when I woke up I was down to 92%. I will be taking the wireless charger with me to work tomorrow so I will know for sure if it stops charging at 100% or if it does what you are describing.

Both my gf and I bought our Galaxy s6 edge on release day at Bestbuy and with the preorder the wireless chargers we're included free. The past 2 nights both of our phones have had this issue. Mine only charged to 87% yesterday and 93% today. Hers was at 88% yestwrday and 96%today.
I'm curious if the wireless charger takes a much longer time to completely charge the device to 100%.

For me better wireless charger than wire... I think I've better battety life.
With wireless charging I use wire charger included.

iirc thats supposed to happen to prevent overcharging.

Does wireless charge work with OTG plugged in?

Thats makes sense but I've my wireless charger next to be bedside table and I was woken up but the charger plugged in notification sound constancy going off.

It would be really great to turn those sounds off. Also, you have to assume that there's some battery level where it will restart wireless charging, right?

This is what I was hoping for when I said above that I saw it hit 100% and then overnight it drained to 92%. I would hope that if it falls below 97% or so that it would charge again to 100% so it keeps cycling but right now I am not sure if it does it.

I've noticed the exact same problem with mine. I got the free Samsung official wireless charger from Best Buy. The phone charges to 100% every night but when it finishes, usually around 3 or 4 a.m., it just stops charging and doesn't start again. So this means that every day when I wake up my phone has drained to around 90%. This never happened with my Nexus 5 on a generic wireless charger. It always kept it topped up until I remove the phone. This is really annoying.
BTW if you go into the settings menu under battery, you can see exactly when your phone stopped charging.

that sounds like the best reason untill i hear anything more concrete, might try charging tonight direct via the cable and see if it hits 100%
but with no replaceable battery they may have introduced this to prolong the life of the battery.

I totally get not overcharging. But it's got to kick back on at some point. Leaving your phone on a charger overnight should basically guarantee 100% in the morning. Maybe at 97% it could kick back on, or at 100%, it could go into a trickle mode. I'm sure some custom development will come along and fix this problem.

Here's hoping for an update or something through soon. Gonna test a full charge before tonight and see if it actually states it reaches 100%
I'll post what I find.

Samsung tablet SM-T805 charging issues...

For the past 3 months my tablet has been struggling to charge.
I would plug it in, it would show the charging icon on the battery, but it won't charge. Sometimes it will INCREDIBLY slowly. Other times (most of the time) the charging percentage will decrease while its plugged into a charged.
I have tried:
1.Soft reset
2.Hard reset
3.Removing micro sd card
4.Different (original) lead
5.Different (original charger (3 in total)
6.Opening it up and disconnecting the battery terminal for 5 mins
7.Holding down power while battery disconnected
8.Connecting the charger FIRST before connecting the other end to the mains.
Im getting nowhere. Currently its on 1% and just wont charge.
To me it could be the charging port or the battery. How do i determine (without spending heaps on a battery) what to replace first?. Is there anyone else with this problem?.
Thanks

Just now i plugged it in charge. The tablet is off as its on 0%. It took 30 mins to get to 4%, then it went back down to 0% instantly.
But like i say, when it DOES have a charge, the charge is usually decreasing as the charger is plugged in, till it reaches 0%!. Only sometimes very randomly and very rarely will it actually charge properly, and when it does it operates perfectly with it OFF the charger. So it doesn't drain dramatically off the charger.
Right now im struggling to even get a charge out of it now.
Can someone help? charging port or battery fault??

Its on 30% now, creeping up slowly. So strange.
Have you seen any other cases the same to say it is the battery?

When a device charges strangely fast or agonizingly slow, it's typically the battery, also, randomly discharging fast is also a sign.
You could always have a repair take a look with a voltmeter, testing the battery and the USB port/charging components. Or you could do it yourself.
Sometimes it's just the solder working loose on some of the pins from your USB port, you can do a reflow on those solder points.
