I'm kind of torn on this. Cheap accessories can in fact damage your phone. But at the same time, when they charge so damn much for a charger or cable, its highway robbery.

Hello my new love

While this may be an inconvenience it's also a good idea because unregulated and so-called "universal" adapters could be hazardous to electronic devices. I remember with my first Droid I bought a stand-alone battery charger that also had a USB port for charging the phone directly. The battery part worked but when I plugged the usb in my phone went crazy; it was like the phone was possessed and started scrolling through screens and opening apps on it's own. Fortunately Samsung still offers devices with user-swappable batteries so you can carry spares which could decrease the inconvenience of being without an official power adapter. My question is that many companies also offer external power packs to use with phones. Will these new chips make the phones not work with those universal power packs?
i'm really wondering if they would be able to do this for chargers, maybe for headsets, etc, but not for chargers!!!!
More reason to buy Motorola. If samsung tries to copy Apple they can rot like them.

Take duplicate copies of the same circuit and run one with clean power, the other with dirty power. The one with the clean power will run faster and with less heat generated, as well as will remain in operable condition far longer than the one supplied with dirty power, all other things being equal. The MTBF (Mean Time Between Failures), drops precipitously and directly proportional to the purity of the power source signal. CPUs will run faster and cooler, they will last longer, and the overall user experience will therefore be a better one.
You may also know (and may have read on our forum), that some of these "dirty" power issues can manifest as problems on the phone by causing so-called "ghost-typing", where while the power adapter is plugged into the phone the digitizer has difficulty recognizing exactly where your fingers are touching the screen. This can cause it touch or select other areas of the screen that are no-where near your finger, seemingly as if there is another person or "ghost" touching the screen at the same time. In some cases this "ghost-typing" can be so bad that the phone will - even without touching a tall and completely on its own make phone calls or texts to numbers in your contacts list, or to random numbers, will select apps and run them, close windows, change settings, take photographs, etc. Once the offending power adapter is disconnected, the phone functions completely normal again.
Furthermore, if there's one soapbox I get on often, it's proper care and charging of Lithium Ion Polymer Pouch type batteries (the types used in most phones of today). These batteries are very picky - to use a common descriptor, with respect to how they are charged (at what percentage of capacity or discharge charging is started), at what rate the are charged (mAh, i.e. 750mAh, 1.1mAh, or 2.1mAh, etc.), how much they are charged (percentage of rated capacity, or maximum voltage levels), and how much they are discharged (minimum voltage level). They are very volatile chemistry and if not charged in the ranges as specified by the manufacturer of the phone when they specify the chemistry to meet certain needs, the results can be anything from poor performance, to shorter total lifespan, to complete failure to respond to a charger, to self-destruction and explosion/extremely high temperature fire.
I've opened dozens of charger modules, those from the big named cellular phone manufacturers, those from the big named phone accessory manufacturers, and those of the cheapo Chinese knock-off companies, the $5 chargers. To compare them is similar to comparing a BMW 5 series to a go-cart. Both will get you there (eventually), both burn fossil fuels, and both have a seat and 4 wheels, a steering wheel and a motor. The quality and perhaps even more importantly safety of the trip and likelihood you arrive in one piece in one versus the other are unfortunately incomparable. The number of components, quality of those components and engineering which comprise two are beyond compare.
I will post some photos when I get a chance, but safe to say the OEM chargers have not just some, but LOTS of components, usually several MSIC (Medium-Scale Integrated Circuit) chips, quality filtering components and are engineered to provide the cleanest, smoothest possible power. The cheapo's have just a very few components and very little filtering of any kind. To give you another real-world comparison...think of the OEM charger as a brand-new paved Asphalt road, versus one that is 15-20 years old, full of potholes, patches, repairs to the piping underneath, etc. Again, both will get you there, but one is a much more comfortable ride and will not produce wear and tear on the car, whereas the other may cause you a blow-out or at least to need an alignment, both your back's and the car's.
