My phone has a weird bug
from time to time when I connect my Bluetooth headphones, my battery jumps slowly to 100% as if I would charge it and stays there until I disconnect them and wait a bit.
I did reset my phone three times and it didn't help
so far it doesn't hurt my device, voltage is shown correctly in Ampere
Screen attached.
Did anybody encounter the same?

After have Touch HD for 100 daysI, have got a problem with it, it is about battery charging.
When HD turns on, it shows battery is low, then HD turns off automaticlly.
I tried charging battery with AC or USB, the Charging light is on but after hours, when turn on the devices it still shows battery is low, then turns off.
I changed a battery, it goes well, the device is on with all the fuction running well. and the previous battery is working after change the battery again. and it shows the battery is 90%.
But after a day. the problem is back again. and this time no matter what battery I changed, it still shows battery is low. and won't charge. even with the full battery the problem is same.
If you have the experience with this, please I do need your help.
BTW, The rom is from the factory.
Maybe the battery is fine, people have experinced problem with the actual charger. Have you tried charging through the computer?
Yes, I have tried charging with Computer, AC adpator and even Only charges the battery.
But the problem is not solved.
I suspect the HD's battery chip which manages the battery charging maybe broken ( if there is a battery chip)
Disconnect the HD from USB/Wall outlet. Remove the battery. Short circuit the pins in the HD battery compartment with a wire/metal piece. (never short the battery - it may explode!).
This helps in most cases for this problem. If not then warranty is the way to go.
Solved. The surgery went fine, actually just unplug/replug the battery
and now tablet is charging fine, but only when on. If I turn it off and plug the power cable
I have the onscreen b&w animation of a charging battery but not even 1% increase over the night.
Might consider finding a replacement sooner or later.

Hi every body
My nexus behaves strangely regarding battery charging, I've tried different cables/chargers same result. I've emptied cache, no result.
Actually here's where I am: When the nexus is plugged with original cable+charger, Battery Monitor says plugged, discharging.
The flow shows a negative mA value. I tried charging the tablet while it's turned off, full night.
Sometimes I managed to get a full charge, sometimes only 5% increase during the whole night.
The usb port seems ok, I can plug it on a computer, copy files both ways, speed is ok. But still no charging.
I've read lots of forum posts concerning battery problems with nexus7, my understanding is that I'm facing
a hardware problem, not software. I have to open it and clean/check the link beetween usb port and the battery charging circuit.
Is there something else I can try before trying surgery?
thx
Hello, it has been happening to me for last 2 days that when I put the phone on charger, the battery sometimes charges at an extremely slow rate (14% to 23% in 1.5 hrs), and sometimes it even discharges while the charger is connected. I am attaching the battery screen here.
You can see that first it goes down from 100 during morning to evening. This is normal behavior owing to my usage. Then I charged it and up goes the curve with a high angle because I use a good charger. This is also fine. Then I disconnect and heavily use the phone again and then put the phone on charger overnight. This is where the problem starts!
Now you see, first of all the battery starts going up then it suddenly starts dropping while still on charger. I woke up to find 23% battery after charging overnight. I noticed in the screenshot that my phone was constantly waking up all night long, may be this could have been the problem. So I connected it to charger again to see the battery level rising in front of my eyes. But again, after 3 hours I found that my battery is 51% and the curve has started to fall down again, and this time there were not enough wakeups.wakelocks.
I am using a powerful charger. It is made in china but it charges all the phones in my home perfectly. I also tried on another charger (also probably china) with the same results on my phone only.
I am using the stock rom, unrooted (can't root version 182.*.*.*)
Do you have thinks running in the background while you charge? Mines charges a lot faster if I turn off internet, kill background apps.
Also is it overheating while chsrgeing? You get a better charge if the phone stays cool
And third your phone might think the charger is a computer. I say this because mines charges really sloe when I connect it to a computer, like 12% per hour. Try a third charger, diffrent brand and wattage compared to the ones yoive tried. it might help.
yes there are background apps but there hasn't been a change which triggered this. the background have worked fine before.
no overheating issue. in fact, this device always feels cooler.
I've always used this charger, my whole family uses it without any issue but now the problem just started happening to me. and even with me the problem is not constant. I just charged up to 50% without any problem. there is one thing left to try. that is, I should try to restart in safe mode and try charging in that mode. if that works fine then it's definitely an app, otherwise the issue may be bigger.
So as the title indicates, for whatever reason the nexus 4 is discharging after reaching 100% on the wireless charger. Now, this would be fine if it continued charging after it drains to a certain battery percent, but sadly that is not the case. When I take my Nexus 4 off of my wireless charger in the morning, I see that it has been 'on battery' for 7+ hours, and the battery is usually between 70-80% which isn't enough for me.
If it helps, here is some information that may be useful:
-My nexus 4 is rooted on 4.2.1
-My wireless charger is called "MoKo Qi Wireless Charger 3-Coil Charging Pad"
-I've tried restarting my phone, but the issue persists
-The wireless charger works at full speed with no issue (apart from the charger turning off when the phone is at 100%, and only removing and putting the phone back on it will turn it on)
Now, I've seen some threads where people say their phone isn't at 100% when they take their phone off, but they mentioned that their phone starts charging when it discharges to a certain percent (say, 95% or something) but sadly mine does not.
Any help is appreciated, thanks in Advance!

Edit: If it helps with anything, the charger makes a faint 'ticking' sound every half a second ONLY when the phone has reached 100% and continues ticking until I remove the phone. The ticking sound persists even while the phone is draining overnight on the charger. I have also tried to test if letting the phone reach 100% then draining the battery while it is on the charger by leaving the screen on changes anything, but it seems it doesn't matter whether the phone is 'awake' or not.

I don't understand the problem. Are you reporting fast discharging of your phone after 100% has been reached? Or you are reporting that it doesn't start to charge again when the phone drops from 100% to 95% or whatever?
In the second case I suppose that your Charger works in this way, and nothing can be done.

It would be the latter, the phone doesn't start to charge again when the phone drops from 100% to like 80-90% overnight. And something CAN (and HAS) been done, I hooked it up to a $10 Woods Model 50001 Indoor 24 hour mechanical timer, and made it turn on/off every 30 minutes during the night/morning. It works perfectly now, my phone is always at 99-100% when I wake up since it doesn't idle for 7+ hours, maximum it ever idles is 30min.
I was just wondering if it was an issue with all chargers, or is it just an issue with my phone... I'll test it with my brother's nexus 5 some time and see if it still happens (without the mechanical timer).
I'm facing problems with charging my phone for a long time. I've already tried some roms but my phone doesn't charge in any of those, staying on the same % for a long time and sometimes decreasing it. I've tried many chargers, and all of them show high numbers on Ampere App and charge normally another phones, but not mine. When sometines I can charge, the battery has a nice duration on using, but to charge it is very slow, to get out of 0% take hours, sometimes doesn't even starts to charge. Anyone knows what I should do to repair this? There is any rom that the charging is normally with no kernel changes or something?
