During the day, charging is difficult, since I carry it around in my pocket. Software should be able to stop charging at a specified point, shouldn’t it?
I’m not annoyed by the message, but by the alarm, which sounds at high volume in the middle of the night. How can I prevent this type of alarms? I don’t use the Do Not Disturb mode just for fun…
It’s also strange that this warning doesn’t appear every day (night, actually), which I would expect when I do the same thing every day.
Being woken up by an unwanted alarm three times in the last two weeks is no fun at all! I think it started after the last software update, a few weeks ago. (5 May, security update)
I agree, but this requires the function to be either built into the OS or supplied by an app with root access. There’s a lot of discussion in the forum. Have you read this topic from the top?
To take this further, you can contact official Fairphone support.
Leaving the phone charging all night is not recommended (also much discussed). If you need to leave it on at night but not receive calls, put it in Airplane mode.
I was triggered by a post on this subject from a Samsung Galaxy user.
On my FP4, I went to Settings → Notifications → App Settings, here you get a list of apps, but system-ui is not in it,… but… in the top corner on the right, there are three dots: tap on them and you’ll get 1 option: show system. Nothing seems to have changed,… but, if you scroll down, System-UI is in the list! Tap it! Now you can see the notifications that are switched on and those that are switched off. If you tap Battery, you can choose to make it Standard, or to make it silent. I’m a bit confused, because my current settings tell it to respect my do not disturb settings. Last night, it woke me at 5 AM, though. Not with the standard sound (in my case Fermium), but with Cesium, and not at amoderate volume, but at max volume, or so it appeared in the dark of the night.
As for the notification itself. I doubt that it is intended to educate the phone user to pull out the charger at 80% (for which no notification can be set, afaik). I think the system has stopped the charging process, since the battery was full (in my case) and it is issuing a warning that the charging process will not start again automatically. You will have to pull out the charger and put it back in for the charging to start again. So this alarm does NOT mean that you have to wake up your family and have to evacuate the room, building, street or city because of an imminent danger coming from your phone.
Thanks so much, Richard! I’ve just changed these settings based on your walkthrough, and hopefully that take care of the alarm. It most recently sounded for me early Monday morning, and while my phone was on Do Not Disturb. I also noticed that the alarm ringtone is not one I’d chosen Mt’s. I think you’re onto something regarding it happening when the battery reaches 100 percent. I usually unplug my phone when it gets around 80, but, the last time I heard this alarm, I’d accidentally fallen asleep before unplugging the phone.
No, it appears not to be the feature, but a bug after all. Last night I was brutally woken up at 4:12 AM by Cesium and this warning. The warning settings had not changed: silent warnings and no ignoring the do not disturb mode. What I noticed, was that I had received the silent warning much more often since my last message, like every night (no sound!). So, it is SOMETIMES so that the alarm sounds, regardless of the settings. This suggests that the warning can be triggered in multiple ways and that one of these ways, the user settings are ignored or not used at all, like in hard coded. I had the call reopened and switched battery warnings off in the system-ui settings. I prefer not to switch off warnings, because of the obvious function of a warning, but, in this hot early Summer, it is difficult to catch any sleep again, after being woken up by an alarm with the intensity of a fire alarm.
I’ve seen the message a few times, but last night at 06:30 is the first time I’ve gotten the full volume default alarm that continues until dismissed. The actual alarm screen had text which I didn’t quite read in my sleep, but something regarding temperature and an error id in the form “height_usb_ntc_xxx”. The phone had been plugged in 5 hours at that point with the cable securely connected. I speculate the alarm may have come 10-20 minutes after the System UI notification, based on when I remember being woken.
Also just found this related thread with a screenshot showing the alarm message with even more impressive English, although missing the error id I saw: Error Message - "Height USB NTC Temperature"
Hello everybody,
This also happen with my FP4. I bought it last october and this message showed up 3 times since then. And the message comes with an unbelievable loud and annoying alarm sound which scare myself and my wife out of bed everytime. She is very very jumpy and everytime she almost gets a heartattack.
But it is impossible to turn the sound of.
Yes of course I started to not load the phone at night, but sometimes I just forget it and have to do so, otherwise I do not have a morning alert for wake up.
If anyone has a solution on this, it would be very appreciated.
I use the official fast charge cable and adapter from fairphone. I purchased it together with the phone.
I’d like to chime in to keep some momentum on this topic. I recently got a Fairphone 4 and this week also experienced this notification (only once so far). It woke me up at 5 in the morning by this incredibly loud notification - despite the “Do not disturb” mode being active! As others already mentioned, not the best experience. Thus I’d be quite grateful for this to be fixed (as I unfortunately need to rely on charging the phone over night, suboptimal for the battery as it is).
I have had this happen too a few times, it usually happens when I charge my phone with my rather low-quality USB powerbank. The powerbank I use gets very warm when I plug a cable into it for a while, so maybe the error message is a warning that notifies the user that some thermal sensor that’s part of OTG capabilities(?) has crossed a threshold and that the phone stopped charging to prevent overheating? It only happens on my powerbank, not on my wall adapter or any other power source.
I have had this message appear once or twice about two months ago too. Weirdly it hasn’t happened since, so I didn’t think much about it until I stumbled across this thread. I will advise if the message appears again and pay closer attention to the exact circumstances.
I haven’t had the alarm again but I do still occasionally get the “Please reinsert the USB” message and rarely I’ll also find the media volume has been bumped to 100%.
Just happened to me too. Both the loud alert in the night and then the poorly punctuated systemui notification. Has anyone had any message back from fairphone other than don’t charge at night (which is ridiculous as every phone I’ve ever owned was fine with that)
I’ve seen this notification a few times while charging, never had a loud alarm though. Just now it occurred while I was watching a video on YouTube. The video sound weirdly faded out and then it was paused. I saw a dialogue box flash up and disappear within fractions of a second. Afterwards I found the notification in the drawer. The phone was fast-charging at around 50 % and kept on charging uninterrupted and unimpressed by the message. I believe I have once seen it while I was looking at AccuBattery (a battery monitoring app) and it appeared to coincide with a rather high temporary spike in battery voltage.
I also got this warning today. I didn’t hear it though, because I was in another room with headphones. But when I came back, the volume was all bumped up to 100%, which I never do.
I usually charge my phone to around 80%, but today I forgot that it was charging.
Interesting: I got a notification that it’s “charged enough to turn off energy saving mode”, which happens at 90%, which was 31min AFTER the System UI Warning, so no way that charging to 100% is the fault!
