Wireless charging plate does not stop charging after battery full

[Ekin Koc]

Mine's been sitting on wireless chargers all the time (I have one on my bed stand, my phone stays on it all night. And one on my desk, well, it stays on it when I'm working). When it gets full, the light goes off, sometimes goes back on for a couple of seconds. If I pick it up and check something any lay back, light goes on and stays that way for 5-10 minutes. In any case, phone does not heat up around full charge, only when it's charging from lower percentages.

Had my Lumia 920 on the wireless charger overnight. The light never went off. I checked the phone and the battery was showing as full with the plug icon over it which show that the phone thinks it is fully charged. I then pulled the phone off the charger and put it back on and I did get the long blink that the manual says will happen when the phone has a full charge, but the light stayed on. I wonder if Nokia changed something in one of their Extras+Info updates. It seems to be working fine, but the light just never goes out.

Charging doesn't stop when you have the phone plugged into an ac outlet. That sounds like a firmware thing. Not many devices are programmed to switch to the battery or turn off once they have reached a full charge.

On my 7.5 device I click the power button to actively **** off the screen to make sure it doesn't stay on all night

I would imagine that it is on your phone to stop the charging. The charging circuit in the phone should stop the flow of current when the battery is charged on the plate just like it should when your phone is plugged in. Lithium-ion batteries do have a disadvantage in the fact that they can catch fire if they are overcharged. Several companies/products have made the news for this in recent years.

Update: charged all night on the plate and it was fine I'll keep an eye on it. I wonder if there was something in the last update Nokia sent out that changed this. I noticed it the battery saver screen initially there was no line predicting how long the batter would last like on WP7.5. After nokia's last update this was back. That is also about the time my phone started acting funky. So fat after soft reset all is good on both the charging plate and stand. Anyone else notice this?

I am experiencing the same issue where the light on the charger does not go off. Soft reset didn't have any effect on mine.

my l920 gets really hot when using the wireless charger but charges to 100%

Mine charges to 100% but it doesn't turn off the light, keeps charging past it.
Also, I just did a full factory reset and still having the issue.

Update: mine inconsistently goes away. Sometimes it would do the long blink for a few times.

So... are we certain the light is SUPPOSED to go off? I am not sure, which is why I ask, but I wouldn't think that the presence of the light necessarily means it doesn't stop charging.

Mine is on when charging, then flashes for a while, then goes out completely.

Normal charging, light goes off when battery is full.
Nokia Wireless Charging Plate. User Guide - Charge your device - Nokia - USA

Long blink when battery is already full when you put it on the charger.

Fast blink indicates charging problem.

Hope this helps.

Thanks for this.

So then here is the next question... if the light doesn't turn off is this a fault with the handset or is it a fault with the charger?

I came up with a theory yesterday...hmmmmmm. I think it is the fault of the phone software.

I think the light on my charger wouldn't go out because of a certain App I was running (I do not know which one however)... Put the phone on the charger yesterday, and eventually (after ~3 hrs) it was fully charged and the light slow blinked for a while, maybe 5 minutes that I notice.. But eventually the slow blink would stop and it became a full light again.

Anyway, over night, I took the phone back off the charger and just had it sitting by itself. Well, it died in the 7 hours I was sleeping. COMPLETELY died, down to the "Red Battery of Death" died.

So, my theory...I was not getting the light blink because some app was running in the background and eating up power like NOBODY'S business. It was basically eating it nearly as fast as it could charge it...so the phone wasn't staying at 100% very long and it would need to top up again. No idea what was running that killed it that fast...maybe Skype that I had opened up the day before? The phone has been on the wired charger at work for the last 2 hours, nearly charged up.

My phone does't power on at all :'( I tried turning it off but it is dead.. any suggestions as to what can I do here?? I tried calling my number to see if I get calls but no.. nothing.. it is not working..

Just hold Vol-down+Power for about 10 seconds and the phone should vibrate.

Yea i think we can conclude it's either the software's fault or my phone is defective (which i think it is it has like every single problem listed LOL) because i just changed to a different charging plate and even if the battery's at 100% the white light still stay always lit

I can confirm another user that just got their charging plate and the light goes off as it should. I wonder if maybe the early batches had an issue possibly.

My replacement phone is having this issue where the light on the plate stay lit even when the battery is 100% already, my original phone didn't have this problem. You're right, could be hardware issue.
