I've dug through the other wireless charging threads and even tried posting my issue within a couple but cannot seem to get a response. So here we go:
I have owned the WCP-700 Wireless Charger since January. It worked flawlessly with my Nexus 4 and has been working flawlessly with my Nexus 7 (2013) as well. By "flawlessly" I mean that it charges the Nexus 4/Nexus 7 until full. Once the Nexus 4/Nexus 7 is full the blinking green light at the top turns a solid green and it stops charging the device until the battery falls below 95%, then it starts charging it again (AKA the "Trickle Charge").
However, with my Nexus 5 I am noticing that while the WCP-700 charges the phone just fine, it doesn't stop charging when the device is full. When the Nexus 5 indicates that it is 100% full, the wireless charger continues trying to charge and the green light remains blinking. If I leave the phone on the charger overnight I wake up to find the phone rather hot, which concerns me.
Does anyone else have experience with this charger or the WCP-300 that can confirm whether or not your charger stops charging the phone when full, as it should? Does your green light turn solid when full?
I hate the idea of having to get a new wireless charger when this one worked so well with the other Nexus devices, but for the time being I've resorted back to plugging the Nexus 5 in with the stock charger to prevent from overcharging it.
I have the same charger and my phone doesn't get hot. The light doesn't turn solid green either but I think it stops charging

Overcharging isn't really an issue as there is a chip that shunts the power when the battery gets full. Plugging into your USB charger would still overcharge it if overcharging were a problem.
People everywhere and concerned about the lights on their qi chargers not responding to a full battery and thus become concerned with overcharging. Right now it looks like the N5 doesn't communicate back to the charger when full, honestly it's probably less the phone and more something in KitKat. Regardless, the charging circuits in most new phones are designed to prevent overcharging.

I have the same charger and I personally love that the N5 exhibits this behavior! My biggest gripe about the n4 is that the phone stops charging before 100% and then remains awake and drains down to 95% or lower before charging again. With this phone it always is "charged." Same with the Nexus 4 Orb. Charges continuously like a cable charge would... and it's about time!
Fun fact... you can get your n7 (2013) to charge fully on wireless by shutting the device off while it's on the charger. The device will not stop charging and you end up with a truly full charged device when you take it off the charger.
It is impossible to overcharge the Nexus 5. Wired or wireless.
Thanks for the replies guys. What you are saying makes sense. Concerns alleviated. :highfive:
I disagree. I own a power outlet with build-in Watt meter.
When I charge Nexus 4 you can read continuously 4-7W power consumption. When the phone is charged this number drops to 0 and the led turns green.
When I charge Nexus 5 you get average 6-8W power consumption, but at the end, when the battery is full at 100% you still get around 3W power consumption, even hours after the battery is charged. All this overcharging is easily detected when you remove the device from the charging pad and you'll notice the produced heat on the back of the Nexus 5.
Unfortunately I experience the same issue with Nexus 7 (bought in EU), so basically I have only Nexus 4 properly working on two different wireless chargers.

Will it eat through my battery cycles though? (will it shorten the battery's life span?)

I was charging my tab and now the tab if off. When i try ro swicth it on it does not responed. Its was working less than 30min ago when I putted it in the charger. How ever now if off. Any ideas what might have caused it? Thank you in advance.
Possibly your battery has been allowed to become flattened to the point where it cannot accept a charge from the wall charger. One thing to do is to try and trickle charge your tablet from a low voltage/amperage connection. Either a powered on PC USB port to the charging connector on your tablet, or from a low power phone charger (5v/500ma). It has been pretty well documented that lithium batteries do not like to be drained fully & it may be that the battery in your tablet has drained so low that it cannot accept a charge from the Samsung a/c charger.
Try a trickle charge for 8-10 hours (or longer) on your tablet & see if that gets enough charge into your battery to enable it to recognise & accept a charge from the a/c charger.

Samsung did the same to my tablet after a warranty claim and I had to charge off of my laptop for an hour to get it to wall charge.

I came from Nexus 5 with Qi chargers, so I'll be comparing my experience to that.
Is anyone noticing the phone STOPS charging at 100% via the powermat and doesn't trickle charge to keep it close to 100%? I charge my phone overnight and I'm waking up to ~70% charge and charging off (no indicators of charging on phone or powermat). My qi mats all kept trickle charging at 100% so I wouldn't lose battery.
Now the ***** part - I swear the first few weeks with powermat, I was waking up to 100% charge and suddenly it's changed.
So what are other people's experience with this? There was a lot of discussion about qi chargers that behaved differently based on brand. Some did trickle charge, others didn't.
The further I go using an att g3, the more I want to sell it and run to t-mobile.
Hello,
I was wondering who is charging during the night and who is going also below 15% battery ?

I was having this problem when not using the included charger.
It seems that the phone actually requires to be quick charged (8V 2A) up to 65% or so and will then switch to the usual 5V 2A mode when it's reached this point.
As a result when I was using a regular charger (Nexus 7 charger, 5V 2A) the phone would "charge" but would actually slowly lose battery power during the night.
Gotta watch out for specific usb cables or charger adapters that don't provide enough power (as mentioned above).
I have 2 Nexus 7 FHD (2013) tablets and my Zenfone2 has exactly the same charger, 5.2V 1.35A
A standard cellphone charger is 5V and about 700-800mA.

I turned on Airplane mode and power saver while using a regular 5V Charger, and it was able to charge over night.....just not fully.
I thought I was the only one with this issue. Everything works fine with the included charger but when using my charger from my Nexus 4, it would charge a bit then at times start losing battery. I've used a friend's Nexus 5 charger and it has been hit and miss...sometimes it charges all the way sometimes it charges a bit and then starts losing battery.
Im also using ipad 2 charger..works well as a normal charger for zenfone 2. Especially if your gaming and charging same time..mine does not over heat..but dont recommend to do it always
In fact my question was more about who is charging all night their phones and also who is using his phone when the battery is lower than 15%.
Happy to see some others bugs on the ZenFone 2

i charged my phone twice over night and i does mostly use it to just under 10% before i recharge
I have the wireless charger under my monitors and it looks nice right in front of me so I can see notifications and the always on display but I was wondering if it is bad to keep the phone on the stand after hitting 100%. I heard that the phone is programmed to stop taking in the charge to protect it, can anyone confirm?
Thanks
Mine sits on the wireless charger stand (Spigen) every night, all night. My previous S7 Edge did the same, as did the S6 Edge+ before it. Never had an issue.
I believe that once it reaches 100% it stops taking charge.

Then why its warm all the time, while when plugged in it stays cool after 100% reached?
On the wireless charger im using: Seneo Fast Wireless Charger
It does stop taking a charge when full, the light shuts off.
I have not left it on there overnight and will not due to any "potential battery issues".

This happened to my Nexus 7.
I think the inductive process keeps on generating heat. At least it did for my Nexus 7 even after 100%.
I would NOT use wireless charging on this note 7 since heat degrades the non rellacable battery.
lithium rechrgeable batteries last longer when:
dont go below 20-30 %
dont go above 90 %
dont get hot
I am talking about longevity of the battery
I leave my Note and my previous S7 Edge on my Spigen wireless charger all night, every night. It is not hot in the morning. Once charged, it stops.
HI can anyone tell me if there is any way to resolve this. I think is has started since doing the upgrade to Android 10 earlier this week.
I normally put my phone onto the wireless charger before going to bed and I have noticed recently that when I grab it in the morning the battery percentage is sitting around the 90% mark. I initially thought the charger was not able to charge to 100% but on further examination I see that it indeed charged to 100% after I placed it on the charger and then the charging stopped and the phone ran on battery until I removed it in the morning.
I confirmed this this morning by replacing it on the charger and watching it charge (like watching paint dry ). The charger light was blue while charging, when the phone hit 100% the charger light turned to green but after about 30s it completely switched off and so too did the indication on the lock screen that a charger is connected. Removing and reseating the phone started charging again.
It definitely looks to be software related as I did not have this problem last week. I just wanted to ask if anyone here has noticed this and knows of any workaround?
For the record I am running fast wireless charging with the samsung wireless charger that came with my wifes S8, that charger works perfectly with my older Note8. I have also tried switching to normal wireless charging speed with no success.

Unplug the charger from its power source and plug it in again, causing it to 'reboot'. Let us know the results. Note, there is an option to set the wireless charging to NOT be fast during certain hours of the day. I set mine so it charges slowly while I am sleeping - to put less stress on the battery. Your charger may be a little old as well if you got it with a note 8 or S8 - ?

IMO this is a good feature to stop the wireless charger cooking your battery.
Maybe turn down your AOD brightness or something, to use 10% within a couple of hours of being idle is pretty high. Maybe turning off fast wireless charging would extend the charge time so it finishes nearer to when you wake up could help too.
Thanks for the feedback however it does sound like workarounds for an issue that should not be present (apart from rebooting the charger which I will try when I get home).
For me wireless charging should act just like wired charging in that when it reaches 100% the phone should essentially run off the charger now and not use battery at all. Every other phone with wireless charging that I have had worked that way, this is just plain stupid.
Willhemmens its not a couple hours, looking at the battery graph if I go to bed at 10pm and put the phone on the charger it pretty much hits 100% around 11:30 and then is at 90% at 7am, so it is 10% over 7 hours which is ok in my books, but reality is that during this time the phone has another source of power that it can and should use. It did before I applied the Android 10 update.
I have had this issue every now and again, and I found that rebooting it takes care of the issue.
An update. This morning I tried my wife's wireless charger and when the phone reaches 100% it continues to show the charge icon. Put my wife's note 8 into the wireless charger and it exhibited my problem.
So it looks like this is a problem with the wireless charger and not the phone.
Thanks for the answers guys I am of to try buy a new wireless charger
edit - New charger solved the problem.
