There's no "magic" involved in charging. The standard Apple charger delivers the same voltage and amps to the laptop when used on a 120V grid as when used on a 230V grid. So the type of grid should not matter. 20A fuses are definitely not common in all of the EU, it is much more common to have 10A fuses for lights and other outlets in normal homes, and ...

Apple publishes technical specifications for its products and are available at its website. Have a look at: MacBook Air (13-inch, 2017) - Technical Specifications Under Battery and Power2 it shows: 45W MagSafe 2 Power Adapter with cable management; MagSafe 2 power port As your power bank only has an output of 5V/2.4A, which would be 12 watts, it's little ...

Although discontinued in March 2016, iPhone 5s is still supported for service and parts replacement by Apple (as of this writing). Check with your local authorised service centre for availability.

I'm not entirely convinced the author of the article you referenced did his homework! I've heard that battery improvements from iPhone 6 to iPhone 7 have been incremental. That jibes with battery technology progress in general (i.e. slow progress), and a quick search found this article that seems to back up the "limited improvement" opinion: "... the ...

You might want to have a look at the power management system's logs. There may or may not be something useful in there, but it's free and easy to do - so why not? You can run pmset from a terminal window; it has a number of options, and they are documented in the system manuals. You can peruse the pmset manual as follows: $ man pmset To get right to ...

Apple has better diagnostics than third party plug in, so I would seek a quote / evaluation from AppleCare online or a store if that’s more convenient. The shutdown at 50% should be logged well enough for them to diagnose if you need another battery since that’s exactly what happens when one cell is failing or behaving like the other cells and the ...

Although I really like @Allan's compact answer (first version), I think the danger of a swollen battery should be stressed here. "It happens", however, very rarely. It is potentially dangerous as the battery may catch fire or explode. The device should be disconnected from the power source and not be used anymore as of now. The battery should be replaced ...

There are no guarantees how long any battery will last or that it will or will not swell up. I have had batteries last for 6 or 7 years before losing their ability to be recharged altogether that never swelled up. If you are still under warranty, you should take it back to where you purchased it for replacement. If not,then it will be up to you to buy a new ...

No, it is not “generally expected” that batteries will swell after a certain amount of time. What you have is a defective battery - it happens. It needs to be replaced. The swelling is caused by trapped off gasses from the chemical reaction not venting properly. It could swell and not cause any issues or it could go into a condition known as thermal ...

What’s the harm in asking them to diagnose your battery and not even say anything about wanting a free swap? See what they say and document they had a chance to diagnose things before the warranty ends. My feeling and expectation is Apple would not offer to replace things unless you have them perform diagnostics and they see something amiss or feel it’s ...

I disagree. You should only replace the battery once it stops holding a charge or its capacity becomes noticeably bad, unless you're under warranty and can get it for free.

I have no clue about the Xiaomi, but I charge my power bank while charging my 15" MacBook Pro all the time... Actually, I generally have my power bank charging my iPad Pro and my Apple Watch Valet, which is charging my iPhone and Apple Watch.

At this speed, the Mac will have a dead battery in around 6 years. Probably below useful levels in less than 5 years. As the Mac is already around 4 years old, that means around 7 to 9 years of battery life. Which seems quite decent considering that laptop batteries are expected to last 2 to 4 years, according to a quick Google search. In other words, you ...

Heat kills batteries. It’s not a good idea to keep a battery on the charger constantly, nor should you keep it almost dead. For the best battery life, keep it between 20 and 80%. Try a utility like “FruitJuice” which will also help recondition your battery.
