I have a QI wireless charger in the car - if I dock my Mi 9 it charges fine, but then when it gets to 100% it turns the screen on.
I think it then stops charging, and then a small amount of battery must be lost, then it charges up again - gets to 100% and then the screen turns on...
And repeat!
So once the phone is at 100% its turning the screen on and off every minute or so, very frustrating when driving.
Is there a way to suppress this anyone can suggest?
Thanks,
Bill.

Unfortunately I've no solution for you, but indeed this sounds a frustrating issue! Furthermore, when i have my phone on the following wireless charging stand at night time....

...i don't face this issue. As in, I have it charging throughout the night and I haven't noticed it turn on and off when reaching 100% and the repitition you have mentioned.
My only suggestion is to perhaps try another wireless charger, though this may be slightly over kill as perhaps the same thing might happen with that one. Presumably the charger (or phone?!) is stopping charging at 100% then dropping to 99% and resuming charging etc. Which charger do you have out of curiosity?
I don't believe there are any settings currently that can help you. There is a setting in the Developer Options, but the opposite "keep screen on whilst charging". Therefore whilst this setting is not what you need, reporting this feedback to Xiaomi could result in a new setting to "disable screen on when 100% charging complete" could be implemented.
Do you intend on unlocking your bootloader/rooting etc? As you could ask for such a setting to potentially be implemented into the Xiaomi EU rom or other custom modified rom. Alternatively, when (hopefully) we start to get roms like AOSP etc with lots of features. Lastly, perhaps the best option for you would be to use something like Tasker (rule based automated task app, Google it if unfamiliar), if you do intend to root, as I believe you could use a rule such as "when charging = screen off", which may work.
I got that idea from here:
https://www.reddit.com/r/GooglePixel/comments/9wg8k5/is_there_a_way_to_have_the_screen_off_while/
Same issue here, but on wire. Screen turns on, showing the charging animation, then goes off for a while, then turns on again. Frustrating.
Update: I figured out that the phone 'doesn't like' some chargers as I use many. I have an older 5V 1A Huawei charger and the behaves like above, however, with other chargers it works fine. Previous phones work fine with this chargers too.

I have noticed that when the N6 is on charge, once it reaches 100% and left on charger, the battery starts discharging approx 1% every hour.
I only noticed this when my alarm was going off and when looked at battery usage it was saying 94% but nothing using it - installed GSAM and noticed that once fully charged it starts discharging even while on charge. If I remove charger and re-insert it starts charging again as normal.
Has anyone else noticed this issue. I have contacted Motorola to see what they say, but they are none the wiser and just think it may be a feature of the device/charger but not sure and said to test with another charger.

Not sure, I don't use stock or the stock charger. I would have thought the stock charger trickle charged. I remember my HTC desire used to charge to 100%, discharge to 90 and then charge to 100% in a loop as it didn't trickle charge.
Make sure your using a cable that supports data as well. My stock 5.01 and stock charger/cable does trickle charge.
It's perfectly normal to see this in such devices, though if it were going any lower I'd investigate further.
Maintaining a constant flow to the battery would burn it out so the charge gets it to full and then cuts out, allowing a little discharging and cooling of the battery. Once it gets to certain point, it'll start to juice the battery again.
Sent from my Nexus 6
thanks for the replies - I've not seen it drop below 90%, but I know if remove the charger and plug back in, it will start charging as normal - another thing I have recently noticed is that when you do plug charger in, initially it switches between battery/charger a few times and then starts properly charging - I wonder if this is feature of the phone or lollipop causing this. - other than this phone seems to work fine and have had over 2 days on a full charge
Well got it to drop to 80% while plugged in and it didn't start charging again until pulled cable and put back in
what charger are you using? i leave my n6 on a charger for hours after it hits 100%, and it never ever drops. id even say that when it hits 100% it doesnt stop charging. it keeps charging, with a much less inflow of charge than normal, but its still charging. for about 30min before it stops charging. then it just stays at 100%. sometimes i have it plugged in for 8-10 hours after, never once did it go to 99%. this is while using stock, and custom roms.

The new gen chargers actually cut the power when the battery Actually hits 99% and show it as 100% and stop it charging. But when the 100% drop to 99% (which is not actually visible), it automatically starts charging. But discharging the battery more than 1% is not actually a Normal thing, I should say. I also do charge over-night, never evidenced such thing. I'll suggest you to try with different turbo charger if you have one.
I'm using the stock charger got with the phone. I did contact Motorola over this and they were useless. I know charger works as charges to 100%. But it then just stops.
I have performed a factory reset to see how it goes tonight.
If still no good will speak with CPW and see what they say as don't fancy having to send off based on some of the forum posts
I have no issues with my N4 which has been connected to a power source for days and still shows 100%
I have also noticed that on the N6 when powered off and charge it doesn't show that it is charging
taken it into CPW and they have sent it off for repair - been told 16 days - at least with apple it's near enough same day, shame can't do same with android phones
I had called Motorola uk support and was promised email confirmation of call and also call back this morning regarding the phone and have had neither
back to my Nexus 4 for time being, just hope my Nexus 6 don't come back with any scratches, etc
I use a Qi charger, and notice this exact thing. Charge until it claims to be full, then stop altogether. So I set it on the pad when I go to bed, and wake up to it not charging and being down to around 95%. I was thinking that it was a characteristic of Qi, but when we got another (identical) Qi pad for the wife's Hammerhead, it "appears" to remain in charging mode indefinitely. Our Qi pads have a blinking white light when they are "charging".
what happens if you just plug the charger directly to the phone so not using the wireless Qi charger, do you get the same fault

Hammerhead does act differently to the shamu. I have both and used them both on the same qi.
Hammerhead trickle charges. Charging icon remains until picked up off charger.
Shamu stops at 100%, charging icon disappears. However, when I remove my Shamu, its always 100% or 99%.. Its never lower.

Good question. But judging by the rest of this thread, I suspect that it will behave the same with a wire as with the Qi. I don't ever actually use the wire to charge, since the ballistic maxx case makes access to the USB plug inconvenient.

I wonder if that could be a coincidence....? I.e., either you aren't leaving it on long enough for the percent to drop lower than that, or leaving it on long enough that it initiates a top-up just before you disconnect it.
Ok, so looking at the DT for the device....
https://android.googlesource.com/ke...ot/dts/apq8084-shamu/apq8084-moto-common.dtsi
Look at lines ranging from 823 to 854 for the smb1357 block.
Note low-voltage-uv = 2750000, max-voltage-uv = 4350000
In mv, that would be 2750 and 4350 respectively. That makes for a range of 1600 mV.
The recharge-thresh-mv = 200
Assuming a *relatively* linear voltage/percentage curve, 200/1600 * 100 = 12.5%. It won't be quite that linear, but this is adequate to give a rough idea of the charge cycle breadth in percentage points.
recharge-thresh-mv accepts values of 50, 100, 200, or 300. The smaller the value is, the tighter the recharge threshold becomes. At 50, we would be looking at roughly 3%.
So my conclusion: working as intended.
There is another aspect that becomes involved when using Qi, which is the bq51021. This one has a parameter "resume-vbatt-mv" set to a value of 4270 mV. That is 80 mV below full, or roughly 5%. Judging by only the name of the parameter, it sounds like it sets a Qi charge cycle breadth of 5%, but I don't understand the relationship between the bq51021 and the smb1357. I suspect that the two have to agree for Qi charging to work.

I don't think so. I put it on the charger at pretty much the same time and take it off at pretty much the same time but starting from different % remaining every day... If it did drop to 90%, i would have caught it at least once by now.
update: whatever you do if you are uk customer and purchased via CPW do not take it back to them - i found out today that they are not accredited repairers and they should have advised me it needed to go to Motorola - now trying to find out what is happening with my phone and when to get it back
I'm still trying to understand how my Nexus 6 works with Qi charging, and the results are a bit inconsistent.
I'm using an LG WCD-100 stand and a BlackBerry Blade charger, both of which are reported to work well with the Nexus 6 (in portrait).
I've had my Nexus 6 on the dock on my desk in work this week, and have been keeping an eye on it. I have the screen on all the time (so I can keep an eye on incoming personal emails). Most of the time the N6 charges to 100%. It then stops charging until it get to about 98%, at which time it starts charging again. So far so good. HOWEVER, on a few occasions it did not start to recharge (even with the battery down to the 70's), and I had to remove it from the charger for a few moments and then put it back before it would start charging again.
I'll try again next week (I'm only desk-bound Tue/Wed/Thu) with a different Qi charger, just in case there's a problem with the one I'm using (though I doubt it).
In the meantime, has anybody seen similar behaviour - or is it time to talk to Motorola UK Support?
the charging issue with it not starting again is the same as what i'm having on wired connection - if you install something like gsam battery monitor you can see that it is discharging while actually charging
I also have the LG WCD-100 (from when I had the LG G3) but not actually using it as I think first time tried you have to get it in the correct area for it to charge
I had problems with my Nokia charger. Because this phone is big and the back of the Nokia was less than half way up the back of the phone, the weight of the too of the phone pushed the bottom of the phone away from the charger.. Imagine the phone as a see saw and the top of the back of the charger as the pivot point. Also the unflat back didn't help
I recently got a wireless charger for my Droid Turbo and have noticed that once full the phone keeps connecting and disconnecting, It almost seems like this is by design, it is so uniform, I just want to make sure nothing is wrong with my charger or my phone.
Are other people having this issue?
Android's built in battery monitor resets when I take the phone off of any charger, so It does not show this.

My phone does the same thing, so I am assume it is by design, but if anyone else knows more, I'd love to hear from them as well!
Yes, that's how all modern devices with chargers work. Once it becomes fully charged, the idea is you take it off the charger. If you leave it sit on there, though, it's going to harm the battery if the charger keeps pumping electricity into it, so it stops for a while. Once it hits 98-99%, it's no longer fully charged and begins charging again. Obviously this isn't the best for the battery longevity either, so again, you should take it off the charger once it hits 100%. But the behavior you're seeing here is normal.
The only issue I have is I have a custom sound through Xposed module for when I'm wireless charging and not. Helps to know when you hit the Qi pad "sweet spot". Or if I accidentally move the phone off the sweet spot and it's no longer charging (but I want it to).
Wireless Charging | Xposed
http://repo.xposed.info/module/com.eldarerathis.xposedmodule.wirelesschargingxposed
Somehow my and my wife's LG Nexus 5 is smart enough to stop charging on the Qi pad (when battery is full) and NOT trigger the custom ON/OFF sound -- because I did NOT remove the phone from the charging pad. It still stops charging and starts recharging, periodically but until I PHYSICALLY remove the Nexus 5, it does not chime. It KNOWS the difference between me moving the phone and the battery's automatic circuitry. Or if I put the phone physically back ON the pad, THEN it chimes. But if the Nexus 5 battery charging cuts off/on by itself, it does not trigger the notification.
Yet, with my Moto Maxx, when the battery gets full, CHIME! A couple minutes later, CHIME! A couple minutes later, CHIME! (off, on, off, on, off, on). Very annoying. LG somehow is smarter so that doesn't happen.
I sold my Nexus 5 a couple of weeks ago, but my wife still has hers. On our living room and bedroom charging pads, I see the comparison side by side ever day. Same Xposed module, but Moto stupidly thinks I've "removed" the device from the charging pad when it stops charging the battery because it's full. And then starts back, and then stops.
Well I'll leave the question (striked) below, but my phone decided to make me look crazy. Been testing on and off for 5 hours today after noticing it yesterday. Minutes after posting this question it is no longer doing it . . .
Hopefully it is nothing major, and it was just something that is supposed to happen under certain circumstances.
Thanks
On the lock screen it says charging slowly whenever it is connected to the charger now. I thought it might be the new battery optimisation as I dont remember it doing that before, so turned it off and still says the the same thing and seems to be fairly slow at charging. While the phone itself is turned off it seems a bit faster but I cant be certain.
Can anyone else confirm if their lock screen says charging slowly while connected to a (stock) charger, with the new battery optimisation turned off?
Or if not does anybody know what the problem might be?
Thanks
Anyone else facing issues with wireless charging? Since the A16 update my device has issues, wireless charging stopped working.
Strangely when the device is turned off it still works. Also after a reboot it works but just stops after a period of time. Only way to get it working again is a reboot.
Never happened before on previous firmwares so must be related
I think it's due to the sleeping time in the wireless charger settings (in battery settings/more).
Try to disable it.

Thanks for your reply, much appreciated. However I already disabled that and issue remains. Only way to get it charging again is a reboot.
Funny fact, I "duck taped" the led on the charger so it didn't annoy me while charging during the night so I didn't notice the issues at first. Just wondered why my device needed a refill so soon during the day.
Now I removed the tape so I can see the led and when it doesn't light up I know it's time to reboot my device.
I really think it's because of the .16 firmware hoping next update will solve the issue

Just placed my phone on the wireless charger (official one from Oppo) and it loads. Got A16 today.
@patensas same issue here with version A16. I mean i unpacked my wireless charger and wanted to use it for the first time...did not charge at all - reboot helped. I will monitor this

That's odd. I've never encountered this problem before :O
Mine does charge wirelessly, but it seems like there is no more difference between quiet charging (lower power) and 'loud' charging.
Regards quiet Vs loud charging, I have found no difference either. And I am on A15 still. I had hoped to be able to leave my phone on charge overnight in the bedroom but the fan kicks in immediately and sounds like someone is doing the hoovering! And the fan stays on permanently until you lift the phone off the charger. I.e. useless.
It seems mine is locked in quiet charging, the toggle doesn't do anything anymore. Seems like a proper bug.
Time for little update from me here:
- no issue with wireless charging, always works (except my first time with this charger)
- on normal and quiet mode the fan is super silent, no strange annoying noise whatsoever
- on normal mode charging from 15% to 100% takes ~75-78min
- on quiet mode charging from 14% to 100% takes ~125-135min
Umidigi A3 pro. My phone.
History: Worked fine, started shutting down at battery ~85% (also: "Battery Testing" app says "nearly dead"), decided to buy new battery.
While awaiting new battery, charger cable got yanked. Unsure if this is relevant. Charging still worked OK, phone still shut down ~85%.
New battery arrived. Supposedly the same ("Model: A3") Same markings, BUT no date of manufacture, physically slightly wider, still fits.
Fitted new battery. Does not charge when phone switched on (charging light blinks once, when connected, goes out, does not stay on). Charges normally when phone switched off!
Fitted old battery. Charges normally when phone on and when phone off.
What could the problem be?
I wondered whether the old battery could not take as large a charge rate as the new one, perhaps the new one charges when the phone is off because there's less current demand, BUT this seems far fetched.
Any ideas? Any pointers gratefully received!
Well, I ordered a replacement charging port board. Will see and say what that does, if anything, when it comes.
Question: are there more appropriate/busier forums for this sort of thing, here here or elsewhere?
This seems to be a dead forum. Anyway, for the sake of completeness:
New battery, new charging port board,
Charges when swithched off (charging light comes on).
Charges when switched on, but no charging light.
If charging cable unplugged then plugged back in, as in first post, charging light blinks and goes out. Charging continues.
I will see what happens when charging get to 100%, and also take it off charge, see whether it keeps working when charge gets low, then let the battery go flat, then recharge.

Yes, it works as above. Something rather screwy here. The settings -> battery indicator right now says "charging", the detailed info. says "not charging". I think I will have to live with that, it's not that important.

Thank you. Unfortunately I am reluctant to install that, since my device says extra permissions are required, and that it is an old application which might not work. How true that is I don't know.

That's very strange. I'd be interested to know what these "extra permissions" are.
In my AndroidManifest.xml there is not a single permission listed. You can easily verify this.
And I'm not dynamically requesting any either.
Yes, it has a very low minimum SDK specified. That's so that it can run on very old devices.
Well, after trying again, I get "Blocked by Play Protect", and "application did not install" (really helpful message!). Then after another try it did. Poxy computers.
Anyway. Similar findings.
Disconnected: Power=battery, Status=discharging.
Connected: Power=AC, Status=discharging.
After leaving unplugged for battery to reach 78%m reconnecting still shows:
Disconnected: Power=battery, Status=discharging.
Connected: Power=AC, Status=discharging; HOWEVER battery voltage is shown to be increasing, % is also increasing, until 100%.
Again, no charging light seen, although when unplugged then plugged back in the charging light lights very briefly, then goes out as charging contiunues.
Bizarre.
