This behavior happend to me too. It’s hard to say how often, because I noticed it from time to time, but wasn’t sure about. Today I caught it:
On this picture you can see normal discharging until I plugged it in (USB-Hub of monitor, where its connected every day for charging). You see the green bar at the bottom (“wird geladen”) but the percentage dropped as it would be unplugged. When I noticed this, I tried to get a screenshot but shut down the phone by mistake:-). Then there is some time of using without charging, and the last minutes (after reconnecting to the same USB with the same cable), it started to charge.
So we learned:
The red LED was on.
The cable is OK.
The power is enough.
It discharges although, even a bit faster than before (longest ramp), although without WLAN, without GPS and without Signal.
After reboot, it charged as normal (which I already supposed, based on earlier experience).
There is a second thing to be seen which I don’t understand: This curve started after charging the whole night, at 100%. During the first hour, I used it rarely, but it discharges quite fast. Then, without a reason (as far as I know) it discharges slower. The next fast discharging is ok, I used it for navigation and forgot to plug in to the power supply in the car. But this is a quite heavy load (display, GPS, Bluetooth and data) and discharging is as fast as in the morning without doing that…
The story goes on. Today, I noticed, that the percentage stayed constant at 80%, although the phone was plugged in. I took a screenshot. Then, after a while, I plugged the phone off to accept a call. After the call I plugged it in, but was puzzeled because the percentage was dropped to 72%. But the picture now shows, that the percentage lowered the whole time! (the pictures are starting at the same time!)
To make the confusion perfect: the phone is now charging (without reboot)!
I have the same problem as mentioned before. Phone says it is charging, but battery level is not getting up. When unplugged, level drops (sometimes) or stays the same. Till so far I read no solution! Problem occurs not all the time…
I’m also having this problem. Defintely this isn’t a cable issue - with the very same cable/charger combination, sometimes it works and sometimes it doesn’t. Seems ot be very randomly as well.
I’d say about 1/5 times when the phone is plugged in it actually charges.
This makes it EXTREMELY unreliable. Really makes me lack confidence in the phone which is other than this fundamental issue working perfectl.y
In my case, after rebooting the phone, it jumps up! Yesterday it took a long time (about 45 min) to get from 2% to 11%. I turned the phone off during night. Today, I plugged it in without booting it. The loading-screen showed 11%. After booting, it went up to 50%!
I don’t know if there’s a relation to the fact, that the phone discharges in flightmode about 6% per hour since a few weeks… Some issue in the charge/discharge module?
This is so weird! I hope we will have different experiences with the next software update (1.8)… In the meanwhile check out this post. @therob also reported differences between loading screen and notification bar. Your issue also seems to be related to software.
This happens with wall charger or charging from computer usb port
Rebooting (usually) seems to fix it.
It happened v occasionally before 1.6 upgrade and much more since - now, possibly, about 20% of the time. Seems to be worse when I travel, so it could be something about going in/out of coverage and/or aeroplane mode.
I face the same problem as described above and identified the reason without having a real solution.
At the beginning, I had an old 2GB SD Card and all was right. This card died and I purchased a new one : a 32GB SDHC one.
Since this change, I face the problem described in this thread. By charging on a 220V plug, no problem. While charging on a USB port (on my laptop or in my car), sometimes charging doesn’t succeed.
When is happens, the solution consist in :
stop the phone
remove the sdcard and reinsert it.
restart the phone
It happens sometimes without any identified reason. When I face this problem, the other symptom is that I can’t mount my sdcard on a computer to read or write data. The computer tries to mount it without success.
If someone has a real solution to this problem, I would be glad to read it
I am checkling out this thread, as this morning, despite being on charge overnight, the phone had only reached 60%, and dropped quickly. I have just tried rebooting the phone, so let’s see. It seems to have gained 1%, but this seems quite a large problem so early into owning this phone…
To everyone: Could you please tell us, which SD card you are using? @Cyrille_Vivion suggests that the charging issues could be related to her 32GB SDHC card. See here.
