battery – Screen on when charging on powered off phone

My phone’s screen is always on when I charge it while it is turned off.
It displays this image:

enter image description here

And the screen cannot be turned off. I believe it is not charging either, but I can boot it normally. It charges normally when on.

I believe the issues posted at

are fairly similar, but do no have a solution, as far as I can tell.

Originally, I had the message

Orange State
Your device has been unlocked and can’t be trusted..Your device will boot in 5 seconds

Displayed along the picture of the battery. The phone would not boot (unless I’ve pushed the on button, that is), but the message would continually be displayed.

I’ve followed the tutorial at and removed the 5 seconds boot delay time in Orange State: I don’t see that warning when I turn off my phone or when it is turned off and charging, but the screen still stays on when I’m charging the phone turned off.

usability – Appropriate use of and child-proof alternatives to screwed-down battery covers

On lots of electronic devices with replaceable batteries, the battery cover is secured by a screw.

I understand that it may be necessary to protect against child access to the battery bay, but using a screw necessitates the use of a screwdriver to open the battery cover, which can be inconvenient. It annoys me to no end that I need to open my toolbox, grab my screwdriver, and unscrew the darn thing to replace the batteries.

When is using a screw appropriate for securing a battery cover? Under what circumstances is a simple latch closure inadequate for a battery cover? Are there safety regulations that cover this?

It appears that there are legal requirements that specify that toys intended for young children must have secured battery covers. However, this question covers more than just toys, but pretty much any electronic device that has replaceable batteries. Aside from safety and regulatory requirements, when is it better to use a screw instead of a latch closure to secure the battery cover?

Also, what alternatives are there to a screwed-down battery cover that can prevent young children from accessing batteries while being more convenient than a screw closure?

Any such battery compartment must be “inaccessible” such that “it is not physically exposed by reason of a sealed casing and does not become exposed through reasonably foreseeable use and abuse of the product” (source). This may be very difficult to attain in a toolless manner, but any ideas are welcome.

Laptop battery won’t charge (0%), is it damaged?

My laptop battery won’t charge anymore, sits at 0%, and the laptop only operates if plugged to the AC adapter (it detects the power cord, but charge remains at 0%)
The battery is already 2.5 years old, saw extensive use (at least daily recharge). so I wouldn’t be surprised if it is damaged/beyond repair, but could it just be a software issue? I’m running Arch Linux.

battery life – Multiple Device Usage Monitor App with Cloud?

So I’m in a company where they lend a lot of tablets with the same google account. I want to know if there is an app that can track all the device usage like what app they use, how long is the screen on time, etc. I want to monitor and track all the usage also from the web. Is there any option or any free / paid app for this scenario? thanks!

battery – Macbook Pro think 60W adapter is a 12W one, and won’t charge anymore

When charging my Macbook Pro (mid 2017) with the 61W USB-C Power Adapter from Apple, sometimes the “battery is not charging” warning start appearing from nowhere draining the battery.

By looking up the charging information (using Istat Menus) it appear that the Macbook think that the 60W charger is in fact a 12W one (and it appear that the intensity is negative i.e not charging):

By unplugging/plugging back the USB-C cable (sometimes several times) all comes back to normal

Why is this happening ? (Sometimes when the battery is full and still plugged, sometimes when charging)


  • The “battery is not charging” issue start happening early this year, but the Macbook had another issue with the logic board as well. After the logic board and battery being replaced, the issue is still here.

  • SMC reset didn’t fix anything.

  • A full discharge, then a full charge didn’t fix anything.

  • When using the power adapter from Apple and the USB-C cable on another device (unfortunately a phone and not another Macbook), it’s charging normally.

  • When using another power adapter on the macbook, it’s charging slowly (but coming from a 12W power adapter and a USB-A to USB-C cable that seems fair enough).

Stop ‘Battery 100% Charged’ notifications

I have a MBP 2018. After upgrading to Catalina, when unattended with the power adapter connected, after a while the machine will start chiming every ten seconds and displaying a ‘100% Charged’ message on the screen.

It’s driving me nuts. How can I stop it?

Weirdly, I can’t find any references to this online; there are even some references to people wanting such a notification. It’s a new installation, so I don’t think there’s any custom software doing this. Is this a new Catalina feature?

unix – How to prevent the battery capacity degrading using a PowerBook G4 with Ubuntu 16.04?

I have a 2005 PowerBook G4 which I dual-boot Mac OSX 10.5.8 and Ubuntu 16.04 XFCE. The ‘book runs both OSs quite well but I have noticed that using Ubuntu has the effect of reducing the battery capacity quite qucikly. For instance today, my aftermarket battery was showing “full” at 64% but after using Ubuntu for 45 minutes it went to 0% and shut down. When I recharged it, it only went back up to 35%. This has happened before and I am writing this post from OSX while I re-calibrate the battery. Is there any way to use Ubuntu but be gentler on the battery? I normally use Ubuntu more than OSX as it is still getting security updates and I like some of the applications that run on it.

Update: The re-calibration seems to be stuck at 37% so not going very well.

troubleshooting – Why do I get the “Change the battery pack” message on startup with my Canon Powershot ELPH?

I have a Canon ELPH 300 HS, which turns off immediately (or within 10 seconds, it varies) after being turned on. The battery is fully charged and not at fault, as it was subsequently used in an ELPH 310 without a problem, and the 310’s battery in the 300 resulted in the same problem.

I’ve been combing the net and have found that many others have had the same problem, but few have solutions. There is also this page which says that for the Powershot S3 IS this can be solved by replacing the date/time battery. I would try replacing it, but I’m not sure what kind it is, nor where in the body it’s located.

Does anyone know how to replace the date/time battery, or alternatively have another idea what the problem might be?

I know I can buy a newer camera for less than what a repair would presumably cost (I already have). I’d still like to try and fix this though.

I’ve already tried:

  1. Changing batteries (original Canon ones)
  2. Leaving the freshly charged battery in overnight to charge the date/time battery as per the manual
  3. Cleaning the battery contacts
