I have a 2018 MacBook Pro 13 inch (the one without the touchbar). Over the past weeks, I have twice faced the situation where the charger is plugged in but the battery is draning and I get a &quot;Battery not charging&quot; message if I look at the Activity Monitor or hover over the battery icon. Resetting the SMC seems to fix the problem but it reappears after a few days. Should I continue resetting the SMC each time or try something else? The laptop has a third party warranty but I cannot leave my home due to the COVID lockdown.

I've been experiencing a very annoying problem lately. Often, I've got my MacBook Pro connected to  power when I'm working from the office. At home, I often leave it unplugged until the battery is too low to continue at which point I plug it in. The problem occurs when my device is connected to a power supply. My battery indicator shows 100% charge which is fine. But sometimes the battery starts draining and the menu bar icon says &quot;Battery not charging,&quot; even when it's connected to a wall socket, and it keeps draining until absolutely dry. It doesn't even warn me the battery is running low because it shows &quot;Power source: Power adapter&quot; which I guess disables the Operating system low-battery warning. This has happened on multiple occasions. I've already tried several things, I've swapped chargers, swapped wall sockets, started with as few tools/apps running as possible. But the problem comes back. I also can't really tie this to a specific app or behavior,  AFAIK. Does anyone know what might be causing this behavior and what to possibly do about it?

I've been  on battery cycle counts and checked out my current count on my MacBook (13-inch, Aluminum, Late 2008) - recommended maximum cycle count is 500.  I've had this laptop now for over 4 years and at the 2 year mark I had the battery replaced by AppleCare. The first time I checked out the cycle count was today and it's currently on 1004. Now my question is, is this the cycle count of the battery since I replaced it (as in, it reads the cycle count from the battery), or is it the combined cycle count (as in, it stores the count somewhere and increments occasionally)? My assumption is that it's the count of that battery but I have no idea how to verify this.  Either way, it looks like I need a new battery ;)

I am looking for a way to check the current health of a battery for iOS devices, similar to how  works for OS X.   How can I check the battery health for an iOS device?

I got a brand new mid-2015 MacBook Pro 15", OSX 10.11.3.  Display never turns off even it is configured to turn off after 10 mins in power adapter AND in battery mode. Screen saver (aerial) stays active forever. I tried disconnecting all USB peripherals connected - it did not help.  Any ideas?

I haven't found anything yet so I was hoping maybe someone here had an idea.  I want to kick off an even based on battery on an Apple laptop reaching a certain charge level, or when the battery is fully charged.  I know I can have something run periodically, check the battery level, and decide what to do, but I prefer event driven if possible.

Well, my MBP cable has gone yellow after a while. I've tried cleaning it with water, and also toothpaste (with whitening) and that doesn't seem to have removed the yellow stains. I guess I'll try mouthwash next; I may have to gargle that myself first. Anyone have the same problem? I haven't been keeping it in unusual places, in my bag and on the desk.  On the left is the whiter clean cable.

I have Macbook Air, Mac OS X El Capitan.  There is no warning box shown before the battery is near %15, like it did for Mountain Lion. So I can not notice and my computer goes sleep simply when the battery is off.  And even if it did I generally miss it because I use it external monitor attached to my Macbook Air. And because I play Spotify, I may miss the warning sound, too.  Is there warning box for low battery on El Capitan? If not, is there any utility or software that may help for external monitors and even playing music?

I wanted to know if there is difference in terms of charging the battery when a MacBook Pro 16" is connected to two monitors via USB-C, both with Power Delivery capability.   In this specific case I am talking about the LG 27UK850-W monitors. The MacBook Pro 16" will be connected via USB-C to both of them and use them as external monitors. Since both can charge it as well, will the MacBook Pro  charge faster while being connected to both or will just one monitor be able to deliver the charge at a time?

I recently purchased a Macbook Pro retina display. When I use the 2 pin charger, and I touch the surface of the laptop I can feel electricity passing - basically laptop is vibrating softly. When I charge it with 3 pin, it does not vibrate. I have been charging it with 2 pin for about 10 days when I was not aware of this issue, so would that have messed up my laptop by any chance? To me laptop works perfectly, but I was wondering some hardware internally got messed up.

I have a 2015 MacBook Pro with a MagSafe 2 charging cable. My wife has a new MacBook Pro from 2016 with USB-C. I was wondering whether I could technically (in the matter of electronic feasability) use her charging cable on my MacBook and vice versa with some sort of adapter / dongle, and, if so, where I would get one?

My 1.5 year old Dell Studio 15 notebook computer has a battery and I keep it attached to the notebook but 98% of the time I just plug in the power adapter.  Lately when I unplugged the power adapter, the battery was only good for 10 minutes, and a few days ago, when I unplugged the power adapter, the computer simply turned off.  When clicking on the battery icon on Win 7, it says "Plugged in, not charging":    is the battery dead?  Or can Windows 7 have any option to not charge the battery?  It is a Dell Studio 15, I wonder if in such case, it looks like it can be a manufacture's defect, would Dell replace the battery? (if there was a recall, then they probably would, i think).  The notebook is 1.5 year old.

When I charge my iPhone 4 on my laptop, it starts charging but then it keeps going on and off charging even though it's not touched. It charges fine with a plug charger or with any computers I use at college.  What things prevent a Mac from charging a connected iPhone so that charging can be resumed?

Will my MacBook's battery be damaged if I do not use for next couple of months?  I bought a new Macbook Pro (March 2015) a month back. So far I have not started using it yet. It's charged and box packed as I do not currently have time to set it up for my development work.  Update: It's charged 90%+ but not being used.

Problem: My laptop battery is broken, it never charges. I have to use it at 0% battery and on AC power. Ubuntu 18.04, keeps giving me annoying notification every 5 seconds:   I know several questions have been asked on this topic, but this is specifically for about Ubuntu 18.04. I have tried solutions mentioned for older versions of Ubuntu but none of them work:   Modifying /etc/UPower/UPower.conf Modifying dconf editor ->org -> gnome -> settings-daemon -> plugins -> power   I am surprised that these settings don't point to the same values? I can set different values in these and still nothing happens. Do these settings even work or are they deprecated?   Has anybody else faced this issue? It's very annoying.

I wanted some opinion on my set up here, just to make sure I got the basics right.  I have a Li-ion battery charging circuit based on the MCP73113. This is designed to be a single-cell battery charger.   The battery itself (3.7V, 650mAh) comes with its own PCB with Schottky diode and current regulators as protection. EDIT: Not a Schottky diode. Current limiter and a Protection IC.  By design, they work together just fine.  I have more batteries from the same manufacturer and wanted to make higher capacity packs by putting two cells in parallel. The two cells come with their own PCB, but I only kept one of them, as I soldered their leads together. It seems to work and they are charged and discharged just like regular batteries (3.7V, now 1300 mAh).  However, not all the packs I made work smoothly and I get a failure rate of 2 in every 10 packs. They all start out normally, but occasionally when the batteries are not charged for some time, or are used up, they tend to not work anymore. So far, in only 1 pack I found the voltage to be different (both now below 2V, aka dead).  I assume my method is not the right approach to ensure 100% success rate, so I was wondering how can this be solved. All the controllers I looked into was designed for multiple cells in series, not parallel. Am I fundamentally missing something here?

Many people keep their laptops plugged in and charging when using them at home, and rarely if ever take them out of the home. This keeps the Lithium battery at 100% State Of Charge (SOC), which I understand shortens the battery life. It would seem to follow that the battery life could be optimised if there were some way of selecting "storage charge" on the laptop, whereupon the charging circuit would keep the battery at 50% SOC. This issue has become more pressing now that manufacturers have switched from removable Li-Ion battery packs to built-in LiPo battery packs. I'm guessing that all the necessary hardware is already present, and so this would be a relatively simple software fix. Is this an issue that has already been addressed and for which a solution is already available?
