Hey, Chris. I’m wondering if plugging my iPhone in to charge before bed and leaving it plugged in for 8-10 hours after it’s fully charged is harmful? Thanks for all the great content; don’t let haters get you down!

Is Leaving My iPhone Charging Overnight Bad?
Is leaving my iPhone charging overnight bad?

Leaving your iPhone on charge while you’re asleep shouldn’t have any detrimental effects on the battery. The lithium-ion battery in your iPhone has two modes:

  • The fast charge, which can charge the battery to 80% of its capacity in around two hours.
  • The trickle charge, which will charge the battery to 100% of its capacity over three to four hours.

According to Apple, your battery will lose some of its capacity every cycle, but it will take thousands of cycles before your battery will only hold 80% of its charge.

The modern lithium-ion battery can take thousands of charge and discharge cycles before showing any kind of sign of not being able to hold a full charge. So I think that it’s safe to say that leaving your iPhone charging overnight wouldn’t be bad for it.

FedEx: We Want to Fix Your PC

FedEx: We Want to Fix Your PC FedEx has been around for decades and has always been known as a company that delivers important documents and goods quickly. However, this isn’t enough for this enterprising company that is now looking to expand into the PC repair field. In fact, it wants to be your first computer repair choice. To accomplish its goal, FedEx is going to enlist the services of a computer repair firm known as Getac, a Taiwanese-based manufacturer. Its goal is to address the high level of dissatisfaction that it sees among consumers and businesses by providing a system of overnight repairs for major corporations.

I believe that its mission goal is exemplary and that it could, in all likelihood, succeed if it can meet this challenge. I say this because, when I owned and operated my own computer repair business, my best form of advertising was word of mouth. Fortunately for me, I was blessed with the ability to repair both hardware and software so people were pleased when I was able to get their machines up and running after another company had failed to repair a computer properly. Customers would take their broken systems to either a big box store, which was far away from our area, or a mom and pop repair store, where they would be frustrated by the high prices and often equally high level of incompetence. Even now, an acquaintance from the old hometown tells me that he had his computer repaired locally and that it took him three trips before the shop finally fixed the problem.

In another horror story — this time in our current location — one of our local charities took an infected computer to a local shop. This repair facility would not do a simple repair on the system because the box did not have a Microsoft Windows serial number affixed to the machine. I inspected the box and determined immediately that it was a custom, homebrewed system that was donated and came with no documentation.

I am not going to argue the legality of the operating system that had been installed on the system. However, unless I am totally mistaken, I have never heard that one needed a Windows serial number to do a repair of an OS, nor have I ever done a repair install where a serial number was even asked for during the repair.

However, that is neither here nor there. At FedEx, the company has been doing its own in-house computer repairs for over 30 years. With that knowledge as its credentials, FedEx will first target big business in an attempt to garner consumer confidence. Once this relationship is established, it is hoped that it will be able to expand and offer its services to small business owners from which it can trickle down eventually to consumers. If its attempts are successful, FedEx hopes to bring in other repair companies that will allow it to expand its repair affiliates and provide the best service possible.

To accomplish its repairs in the most expedient manner, FedEx will either have the systems picked up by a courier, or the owners will be given the option of bringing the system to one of the 1,900 FedEx Office locations worldwide. Its services will even provide repair for those computers that are under warranty. In this situation, the computer will be repaired for free, however, shipping and handling charges will apply. For those systems not under warranty, the consumer may find the charges for repairs to be somewhat higher than those asked from some of the big box stores, however, overnight service may be worth the higher fees.

What is surprising to me is that FedEx would choose a time when the sales of PCs are declining. Could it be that it, along with Microsoft, is looking to the enterprise to save Windows? Do these companies know something that the rest of us do not? Only time will tell. I guess if their bottom lines increase, we will know if their choices were right or wrong.

My personal perspective on all this is that a tablet, outfitted with an accessory type keyboard and mouse, makes me happy and I would be content to leave the PC in the closet.

What do you think? Is this a smart move for FedEx?

GM Unveils Volt – Looks Like A Malibu

GM did in fact show its new Volt model electric car, on the companies 100 th anniversary. It did not look like the concept car which had sharp lines, low silhouette and had a rather cool appearance. The Volt model displayed by GM looked like the revamped Chevy Malibu that was introduced as a Camry killer.

Some of the problems that GM is going to face is battery technology. The current crop of batteries are limited and improvements in battery technology should take place in the next few years. At least this is what GM is hoping for. Second is cost. The word now is that the Volt will be under $40,000. I certainly hope that GM can get the cost below $30,000 or they will be parking the Volt next to their unsold large SUV’s & pickups. :-)

Six months after GM unveiled the Volt concept in 2007, Toyota announced it was already test-driving plug-in hybrids — cars that adhere to the two-engine model of all hybrids but allow the battery to plug into the grid and pick up an extra charge while parked. Toyota has been as quiet about its plug-in plans as GM has been loud about the Volt, but it does seem that the Japanese company takes a more skeptical view of lithium technology. “Our thinking is of a smaller battery with a lower initial cost [for the consumer],” says Tasatami Takimoto, Toyota’s executive vice president for green tech.

With GM asking for a $25 Billion dollar loan to retool for the Volt, it will be interesting to see if the Volt actually becomes a reality. Toyota with their Prius may be a tough act to beat.

What do you think? Can GM play catch to the Japanese auto makers? Or is GM, Ford & Chrysler going the way of the dodo?

Comments welcome.
