Suggested December 2023 Ott Explains – Why Your Iphone Charges Fast First And Then Slows Down
If you own an iPhone, iPad or iPod, you may have noticed something a little odd about the way it charges: fast up to a certain percentage and then slower and slower as it gets closer to 100%. I noticed this a few weeks back and since I know practically nothing about current, electricity, volts, amps, chargers, etc, I wasn’t sure if this was the way my iPhone was supposed to charge or not.
Eventually, I tested it out on the iPad too and realized that it did the same thing. It would charge to around 70-80% pretty fast and then would slow down significantly before getting to 100%. Actually, from my calculations, the time it took to go from 1% to 80% was about the same time it took to go from 80% to 100%!
Table of ContentsPower Sources vs Chargers
The first thing to understand is the difference between a power source and a charger. You probably have said the statement below at least once in your life in you own any Apple device: “Where’s my charger?”
Unfortunately, this statement is technically inaccurate. The cable and adapter that you plug into the wall is actually just a power source. It draws current from your wall and delivers a set amount of amps and watts to your iPhone, iPad or iPod. The charger is actually in the device itself. That is why you can use an iPhone charger to charge an iPad or an iPad charger to charge an iPhone.
The charger inside the iPhone or iPad controls the flow of current into the device, not the adapter. If you ever have checked, the iPhone adapter is rated at 5 watts and 1 amp. The iPad adapter is rated at 10 watts and 2.1 amps.The iPhone and iPad Charger
The battery inside your iPad or iPhone is a rechargeable lithium-ion polymer battery. It’s what Apple uses for all their devices, including Mac computers. Apple has a great page that explains a bit about their battery technology, but the best part is this chart they provide:
Let’s take a look at this chart. On the Y axis we have Current Voltage (A/V). A is for amps and V is for volts. The first number is amps and the second one is volts. On the X axis we have the stages of charging: fast charge and trickle charge. Stage 2 is what explains why your Apple device slows down and takes more time to charge when you get past 80%.
As you can see, the number of amps remains at 1 (for the iPhone, 2.1 for the iPad) for the first two hours and then drops off over the next two hours all the way down to zero when the device is fully charged. You have probably also noticed that sometimes when you disconnect your iPhone or iPad from the charger, it could be anywhere from 96% to 100%. This is because of the trickle charging. When it reaches 100%, it shuts off. If the battery starts to drop, it will kick back in around 96% and start charging again slowly.Why Do We Need Trickle Charging?
So this bears the question: why the heck do we need trickle charging? Why not just fast charge all the way to 100% and be done with it? Well, apparently it has to do with the chemistry behind lithium ion batteries, which I have no idea about. In a nutshell, lithium ion batteries react very badly to being over-charged and therefore you never want that to happen.
Trickle charging solves this problem by reducing the current at the latter part of the charging and completely stopping it once the battery is fully charged. That is why it is also not harmful to leave your device connected to a power source even after it has fully charged.

Whether you’re tired of living a 9 to 5 workday or simply forced to stay at home for the foreseeable future, you probably find the idea of making money online more than appealing. One of the most popular ways to do that today is affiliate marketing.
If you’ve ever landed on a blog post or seen a YouTube video before, you’ll have heard of affiliate links. In simple words, affiliate marketing is when you promote other company’s products. As an affiliate marketer, you find a product you enjoy, promote the product, and then earn a part of the profit from every sale.
Table of ContentsWhat Is An Affiliate Link & How It Works
Every affiliate marketer gets a unique link from the seller. Those links are used to track who is responsible for a sale. The link will have a reference name or number.How You Get Paid How To Become An Affiliate Marketer
Essentially, you become an online salesperson for the company when you join an affiliate program. All you need to get started is a platform where you can reach other people and promote goods.
The best part here is that you’re not limited to one company or even one type of product. You can promote items or services from many different companies and earn commissions from all of them at the same time.
To become an affiliate marketer, you need to follow this general strategy:Decide On a Platform For Promoting Goods
Most people think of a blog or YouTube when it comes to affiliate marketing. However, you can choose any social media platform to get started. So if you have a big following in TikTok (for example) – that would be your best choice to start using affiliate links.Find Affiliate Programs To Join Or Products To Promote
Choosing what products and services you’d like to promote will take some time. Here you need to consider a few important factors like how much commission you’re likely to make, and whether you want to be associated with these products and services.Place Your Affiliate Links & Earn Your First Commission
Once you find and join the affiliate programs you’re happy with, all that’s left to do is to create content and place your affiliate links where appropriate. When people start buying the products you’re promoting, you’ll get your first commissions.What Are The Best Affiliate Link Programs?
Choosing the right affiliate link program to join can be tough since there’s more than one factor you need to consider.
What type of products you’d be promoting?
How complicated is the acceptance process?
Do you like the payout structure that the program uses?
Those are just some of the questions you need to answer before joining an affiliate program.
To make your choice a little easier, here’s a list of some of the best affiliate programs out there suitable for beginners.
If you’re completely new to affiliate marketing, Amazon Associates is probably the best place to start. Since it’s the first online affiliate marketing program in the world and is still running, you can trust that it works and is rather profitable.
On the downside, the commission rates aren’t the best. So you might want to look for another affiliate program in addition to this one.
Skimlinks is also a good choice for beginners. The best part about this program is the automatic approval process. You only need to fill in the application to get started.
Skimlinks offers a big variety of products in every popular niche, so you’ll definitely find the right products for you. Plus, you don’t need to apply to every merchant separately – you can promote any Skimlinks products right after they approve your application.
The biggest drawback here is low commission rates. However, it’s still a good platform to get started.
ShareASale offers many different products that you can choose from. The signup process is also free and very straight-forward. The only downside of the platform is the payout threshold of $50, meaning you won’t be able to withdraw a lesser amount.Make Money While You’re Sleeping
From all of the ways of making money online, like selling your photos or teaching an online course, affiliate link marketing is probably the least-demanding one. While it’s not exactly passive income, it still doesn’t require your time and attention 24/7, and you still make money even when you’re sleeping.
Elon Musk explains first SpaceX failure in 7 years
Today SpaceX CEO and founder Elon Musk spoke about the Falcon 9 CRS-7 launch failure that occurred earlier this year. This event occurred on June 28th of 2023 en-route to the International Space Station. At liftoff this flight was nominal, with no signs of possible malfunction apparent. Shortly before first stage shutdown, the flight failed. Today Musk addressed the issues that they believe may have been the cause of this failed mission. There is still no one 100% certain found cause for this mishap.
The preliminary conclusion the team have reached so far is that a COPV helium container strut in the second stage of the CRS-7 craft failed while the craft was at 3.2Gs. Instead of pressurizing the stage, this helium bottle contributed to a massive explosion.
These helium bottles are pressurized at 5500 psi and stored inside in LOX tank. When a strut breaks – like this one did – bad things happen.
Above you’ll be able to play the full statement from Musk as spoken this afternoon on call with the press.
This failure was found using acoustic triangulation. Basically they listened to the bits and pieces and everything points to the failure beginning in this one spot. This is basically the “most probable” failure point, not the most certain place of failure.
The strut in question was designed to handle 10,000 lbs of load and failed at 2,000 lbs. It’s likely this had to do with a bolt on the strut, and Musk suggests that materials will be changed. In addition to this, Musk suggests that all struts will be checked again after all approvals are made – no assumptions will be made from this point out.
While every piece of equipment was checked and approved, Musk suggests that from this point forward, additional checks will be made.
At this time the investigation is not showing any other failures. One strut – one break – one failed mission.
While one of several questions asked this afternoon had to do with the strut’s maker, Musk is being straightforward and saying that he’s not going to name the supplier because nothing good would come of it.
SpaceX relied on the certification of this supplier, and from this point forward will be conducting their own certification in addition to this first certification just to be sure this never happens again.
This is the first mission failure in 7 years ago. Seven years ago SpaceX had 500 employees, now the company has up to 4,000 employees. Musk suggested that it could be that, because they’ve gone so long without any failure, they may have grown complacent.
Musk also suggested that he does not expect that other missions will be pushed forward significantly. He did make certain to say that no “return to flight” dates will be given until all of the data from this flight and failure is gone over.
Additional information will become available through SpaceX and in our SpaceX tag portal as data has been analyzed.
New data shows how slow is too slow
Conversion rate optimisation specialists have been recently shared two new pieces of research which show that page load speed should be a concern for all. I thought I’d summarise them here as a reminder that speed matters!
The first shows data shared by Walmart shows how their conversion rate varies as page load times increases. You can see there is a dramatic decline in conversion as page load times increases to 4 seconds:
Secondly Tagman published research that showed a similar pattern, except with specific conversion rates.How can we review and improve our site performance?
Google has been releasing tools for to help you with your website loading speed for some time now but what is classed as a fast website and does it really impact your rankings?
Google clearly take this area of website management seriously, they want users to be delivered relevant content quickly, and therefore it would make sense that they would use it as a factor in ranking your website. It’s more obvious to see the impact of slow loading websites on your bounce rate than search but lets look at the tools now available to help you make sure your loading times are not affecting your rankings or site conversion.18th November update
Another update on this tool – the Google Analytics blog has announced that this tool is now freely available in analytics without the need for special config. Here is what to look for:Google Page Speed Report(s)
We reported back in August 2011 that reports are now available within Google Analytics which will give you the insights into average page loading speeds along side bounce and exit rates per page of your website. To enable these reports you will need to follow the instructions at the link below:
You can also get an overview of your websites average load time within Google Webmaster Tools, under Labs and site performance on the left hand side navigation.September 2011 update
In September a new announcement on the Google Analytics blog shows how you can go once step further and see whether page speed is impacting on conversion – to help make the business case for improvements.
If you have ever wondered or wanted to show how having a slow website impacts conversions you now can on a page by page basis, the average load times.
As soon as you have updated your analytics settings (in code) as per this article you will start to see the reports within Google Analytics. From this point I would suggest creating a dashboard based on average site speed, slowest loading pages & conversions by load speed brackets. This should form part of the weekly health checks on your website & steps can then be taken to improve areas of the site as needed.Improving your Page Speed New Google tool
Despite all the free tools Google has already released over the years it recently launched a new tool to help website owners do an even better job. This does reinforce how important Google see this area, they are taking this metric seriously when it comes to ranking in websites and while that is unproven I think is now so easy to improve your website you would be unwise not to look at your own website. You can learn more about this new service named – Google Page Speed Service here.
Page Speed Service fetches content from your servers, rewrites your pages by applying web performance best practices and serves them to end users via Google’s servers across the globe.
An alternative tool which offers a similar service and several more features is CloudFlare, I have used this at First 10 Digital, CloudFare have free and paid services – it’s worth checking out!

You know that icy stab of panic when you suddenly realize your Android phone or iPhone isn’t safe in your pocket where it should be?
Sure, features like “Find my iPhone” on iOS or the Android Device Manager can help. But if bad guys have snatched your phone or tablet, they can do a lot of damage before you zero in on its location.
Lock down your iPhone’s or Android phone’s security settings before it up and disappears. That way, if the worst happens, at least you’ll have the grim satisfaction of knowing that whoever swiped your device will have little more than a paperweight on their hands.
Read on for 9 easy ways to shore up your iOS or Android security, starting with a bonus tip…Bonus: Lock your phone with a passcode, pronto
Here’s a tip that’s so obvious—well, to me, anyway—that I’m throwing it in as a bonus. Why mention it at all? Because I still run into far too many people who’ve never bothered to lock their phones or tablets with a PIN, even in an era of Touch IDs (for iOS) and traceable, easy-to-remember “pattern” locks (on the Android side).
Now, if your tablet never leaves your coffee table, that’s one thing. (Although… burglars!) But when it comes to your phone—and the emails, numbers, passwords, online banking apps, and other private data sitting in its memory—well, you’re nuts if you don’t have a lock-screen PIN.
And now, for the real tips…1. Make sure Find my iPhone/iPad and Android Device Manager are up and running
Both Find My iPhone and Android Device Manager can pinpoint your missing devices, lock them remotely, set off their ringers, and even wipe all their data.
But neither of these apps will do you any good if they’re not enabled before your gadgets disappear (and yes, they’ll disappear, sooner or later).
And believe me, you don’t want your first time using Find my iPhone or Android Device Manager to be right after you’ve lost your phone or tablet.
For Android: Go to your browser of choice, make sure you’re signed into Google with the same login as you used to set up your phone or tablet, then visit the Android Device Manager page.
One of two things will happen: either your device’s location will pop up onscreen, or you’ll be prompted to send a notification to your phone or tablet. Tap the alert on your device to grant permission to Android Device Manager to track your handheld.2. Set your device to require a passcode immediately (or almost immediately) after putting it to sleep [Android and iOS]
If you like, you can set your iPhone or Android phone to wake without a passcode after it’s recently been unlocked—say, within a few hours or just a few minutes.
Convenient, yes, but wise? Hmmm. For a tablet that usually sits at home, letting it wake without a passcode within an hour or so of being unlocked is probably OK.
For the phone in your pocket, though, five minutes or less without needing a passcode is a smart move. Personally, though, I don’t allow any of my iOS or Android phones to unlock without a passcode, ever.
Here’s how to see—and perhaps strengthen—your own “wake without passcode” settings.
3. Block access to Control Center [iOS]
Because you can access it from the lock screen, Control Center makes it easy to put your iPhone into “Do Not Disturb” mode without entering a passcode, or switch on “Airplane mode” before your flight takes off.
Unfortunately, Control Center also makes it easy for anyone to mess with your iPhone’s or iPad’s camera, alarm clock or wireless settings—even allowing, say, a thief to put your stolen iPhone into airplane mode, rendering the Find My iPhone app useless.
4. Use a stronger PIN, or a straight-up password [Android and iOS]
There’s nothing stopping you from upping the security ante with a longer PIN, or even a full-on password.
On an Android phone, you can create numeric PINs or alphanumeric passwords up to 16 characters in length, more than enough to stump casual crooks (assuming, of course, you don’t pick a password like “password123456789”).
Meanwhile, I tried creating a 50-character password on my iPhone, and iOS didn’t stop me. Whether you really want a 50-character password is up to you, but the option is there for the taking.
Here’s what you do…5. Encrypt your data [Android]
Good news for recent buyers of new Android phones or tablets with Lollipop (the latest version of Android) pre-installed: The data on your device is already encrypted, rendering it well-nigh indecipherable until it’s unlocked with your passcode.
Older Android phones and tablets, however—including those that have been updated to Lollipop—don’t have encryption turned on by default. Switching it on is a simple matter of a few taps, but it could take anywhere from half an hour (in my case) to several hours before all your data is fully encrypted, and you won’t be able to use your phone or tablet during that time. You’ll need to keep your phone plugged into its charger during the entire process.
Careful, though: Google warns that you could lose “some or all” of your data if you abort the encryption process midway through. And if you want to go back and turn off data encryption, you’ll have to wipe your phone completely to do so.6. Turn on Activation Lock [iOS]
Of course, plenty of phone thieves couldn’t care less about your personal data. All they want to do is wipe and sell your precious handset.
A new iOS 8 feature called Activation Lock, however, will prevent anyone without the proper passcode from reactivating a lost iOS device, essentially turning it into an impeccably designed paperweight.
If your phone or tablet somehow manages to go missing, you can always use the handy Android Device Manager to lock your device and flash a “rescue” message on the lock screen. With any luck, a Good Samaritan will find your handset and get it back to you.
It’s a smart idea, but what if your lost Android phone or tablet is in Airplane mode or otherwise out of wireless range? If that happens, sending a rescue message with your name and number won’t do much good.
Instead, try this: Add a message to your device’s lock screen now, before it gets lost—a message with your name, a phone number (not the number of your missing mobile, of course), an email address, or another reliable means of reaching you.8. Set your iPhone/iPad to send a “ping” to Apple just before its battery dies [iOS]
As the fine print below the setting points out, your handheld will send out a final ping—complete with location data—to Apple’s servers, so at least you’ll know where your iPhone or iPad was before it died.9. Hide notifications from the lock screen [Android “Lollipop” and iOS]
Lock-screen notifications make for an easy way to check your e-mail, text messages, calendar events, and other mobile goings-on without having to unlock your iPhone or Android phone.
Unfortunately, they also make it easy for perfect strangers to read your messages and otherwise take a peek at your digital life.
If you don’t want just anyone—and particularly smartphone thieves—combing through your notifications, you might want to preemptively hide them from your lock screen.
The Apple iPhone rules the smart phone landscape, and the Amazon Kindle dominates eBooks. But the future of their leadership was called into question this week. Today’s leaders will become tomorrow’s losers, according to forecasters. Here’s why they’re wrong.Why the iPhone Will Rule
Gartner “predicted this week that by 2012, smart phones running Apple’s iPhone OS will occupy the #4 position worldwide, behind Symbian, Android and BlackBerry. Here’s what the market will look like in three years, according to Gartner:
1. Symbian: 37.4% (196.5 million units)
2. Android: 18% (94.5 million units)
3. BlackBerry: 13.9% (73 million units)
4. iPhone: 13.6% (71.5 million units)
5. Windows Mobile: 9% (47.7 million units)
6. Maemo: 4.5% (23.5 million units)
7. Linux: 2.1% (11 million units)
8. WebOS: 1.4% (7.6 million units)
There’s much to agree with in Gartner’s prediction — namely, the demise and failure of Microsoft’s Windows Mobile and Palm’s WebOS, and also the rapid rise of Google’s Android platform.
However, I believe iPhone will find itself well ahead of both Android and BlackBerry by 2012, and that Gartner reached its conclusion by making three errors.
First, Gartner probably isn’t giving adequate weight to the types of users on the various platforms. Because iPhone was first with a major multi-touch, full-screen UI, and first with a compelling app store (still the only platform with a compelling apps store), the platform attracted and “locked in” “key influencers.”
These influential people include journalists, podcasters, bloggers, celebrities and others, who will remain loyal and continue to evangelize the platform on Apple’s behalf.
Second, Gartner may be underestimating the impact of network effects, which is the concept that the value of a network grows with additional users. The classic example is the telephone. If you’re the only person with a telephone, it’s perfectly useless. But the device’s value and appeal grows with each person who uses one.
On the iPhone, there is an enormous number of new apps coming online that have two qualities deadly for the competition: 1) they exist only on iPhone; and 2) they involve connecting with other users who are required to use iPhones in order to connect.
In other words, because iPhone has several orders of magnitude more apps and more users than other platforms, the likelihood that network apps exist only on the iPhone is much higher than on other platforms. That means if users want to participate in the coming avalanche of social networking apps, business card apps, GPS apps, multi-player games and so on, they’ll find iPhone to be by far the most “valuable” from a network effects perspective.
In the network effects game, the rich get richer, which means the platform with the most users on networkable apps should get additional users at a much higher rate.
And third, I believe Gartner is underestimating consumer “choice paralysis” that will result from confusion in the Android marketplace.
Yes, Android is appealing, powerful and will gain a great many users. But the mass market will be relatively confused by the incredible number of form factors and options in the Android marketplace. Confusion breeds paralysis, and this will harm acceptance of Android phones.
This idea does violence to the conventional wisdom, which is that people always choose the most “powerful” product, or the product with the most features. But the conventional wisdom is wrong on this point. People gravitate toward the product that doesn’t create confusion.Why the Kindle Will Rule
King of the eBook readers, Amazon’s Kindle, came under attack this week in the form of something called the “Nook.
It’s generally understood in geek circles that nearly all Kindle’s competitors are “better” than the Kindle from a hardware device point of view.
The Nook is no exception. It’s better. But what makes nook such a threat is that it comes from Barnes & Noble, which (like chúng tôi is in position to sell a lot of cheap electronic books.
Game over, right? Well, not so fast.
Even better, the Nook enables book sharing. You can “loan” books to friends and family, and that borrowed version expires after 14 days. Nice!
The problem is that Barnes & Noble made the same mistake with Nook that Google did with Android. It hit the market too late.
Amazon has been gathering users for two years. But what kind of users? Nearly all hardcore book buyers use chúng tôi Those big buyers most electronically inclined have long since purchased Kindles.
The “best” customers for eBooks — defined as those most enthusiastic about paying for electronic books — are already “locked in” to Amazon. They have invested money for two years on books that work only on Kindle. Nook’s color touch-pad and Wi-Fi feature isn’t enough to drag them away from their investments.
So even if Nook or any other Kindle alternative exceeds Amazon’s device in terms of unit shipments, I believe that Amazon will continue to win where it really counts: book sales. That means Amazon will be in a position to bully publishers, dictate standards and generally control the market — the part of the market where people actually pay for electronic books.
Once again, the prognosticators are making faulty predictions based on an over-estimation of a link between product “quality” or feature sets and unit sales, and an underestimation of the power of human nature on the decision-making process.
People don’t make coldly rational buying decisions based on feature sets. They’re influenced by influential people, opportunities for networking, and a wide range of under-appreciated psychological factors.
The iPhone and Kindle will continue to rule well into the foreseeable future.
