Q. I have a Samsung Galaxy 4G LTE cell phone. I recently was considering streaming movies on my phone using Netflix. How much data would this use on average? Your typical movie is between 90 and 120 minutes. Using this average length, approximately how much data would it require to watch an average length movie on my phone?
A. Netflix has three quality settings. Here is the breakdown:
Good quality (up to 0.3 GB per hour)
Better quality (up to 0.7 GB per hour)
Best quality (up to 1.0 GB per hour, or up to 2.3 GB per hour for HD)
Sometimes Netflix limits the bandwidth used by mobile devices. On the iPhone for example, 1.75 Mbps and 720x480 resolution is the maximum. That is 787 MB per hour. Netflix has some test movies like "Example Short 23.976" that show exactly what you are getting, but for some reason that information does not appear on Android devices.
Should I buy the Samsung Galaxy S4 or S3?
Q. Money is not a big deal, I want to know if I should go for the newer version, the Samsung Galaxy S4, or the previous model, the Samsung Galaxy S3. I want to know if getting the latest and greatest is worth the extra money. I am eligible for an upgrade, and am a freshman in highschool.
A. Hi
I'd suggest you to get Samsung Galaxy S4 as I'm already using it. Superb!!!
The Samsung Galaxy S4 has Android 4.2.2, a fantastic camera, a powerful quad-core processor, and software solutions for just about every scenario -- including working as a TV/DVR remote. It's also comfortable in hand and has NFC, a user-replaceable battery, and a microSD storage slot.
At 5.4 inches tall by 2.8 inches by 0.3 inch thick, the Galaxy S4 is actually 0.7 millimeter thinner than GS3, and at 4.6 ounces, it's 0.7 ounce lighter as well. Yet, the S3 and S4 generations still look so similar, you might not know the difference if you're not looking closely. When in doubt, flip the S4 over to see the new tiny black-and-silver diamond design on the black mist model, or a similar pinprick design on the white frost edition. As with the Galaxy S3's brushed-plastic backing, the newer generation is so reflective, you could use it as a makeshift mirror.
What Micro USB cable that provide fast charging?
Q. Hi,
I bought PowerGen 3.1A Wall Charger, when I use with original Micro USB cable that come with my Samsung Galaxy S4, the charging current is 1.9A, when I use with a generic USB cable, the charging current is only 700mA. (I have a way to test the charging current)
Does anyone know which Micro USB cable that carry fast current, such as 1.9A like original USB Cable that come with S4, or even better, carry up to 3.1A that this Wall charger provides?
Thanks All.
A. One - it is not a "charger", it is simply a power supply. The battery charge control circuit is inside the phone.
Two - re. the 3.1A, you can't do that. The power supply acts like a (nearly) constant-voltage supply and the phone presents an effective series resistance, resulting in current E/R. The only way to force more current into the phone would be to increase the voltage output from the supply. This would likely burn up something in the phone - maybe the battery.
Think about it: Some of the outlets in your house are likely 20 amp outlets, wired with 12 gauge wire. Others are 15 amps, wired with 14 gauge (smaller) wire. Will a 100 watt light bulb draw more current, hence more power, hence give more light, on a 20 amp outlet vs. a 15 amp? Of course not. The outlet supplies 110 to 120 volts, the bulb has an effective resistance when running up a little more than 100 ohms, resulting in a little less than an amp of current and so a power usage of 100 watts. It doesn't matter how much current the outlet can supply, as long as it's at least as much a the load requires.
Regarding your 700 mA problem - that would have to be one very poor piece of USB cable to limit current in that way. Let's do the numbers...
Assuming the Samsung cable had 0 ohms resistance, then if the phone is pulling 1.9A at 5 volts, it has an effective resistance of just 2.6 ohms.
5 volts at 0.7 A would require a total R of 7.14... call it 7 ohms. So the generic cable would have to be adding 4.4 ohms to the path. Or 2.2 ohms per side (2.2 on the +5 side and 2.2 on the ground side).
Even if it's #30 wire, it would have to be 22 feet long to add 4.4 ohms to the path! (#30 is about 0.1 ohm/foot)
But, you could just try looking for the fattest Micro USB cable you can find and see what happens.
Keep in mind that current to a phone is not only charging current.. the phone uses different amounts of current at different times, depending on screen on or off, network conditions, etc... and even battery charging current varies a LOT over time. I wonder if the real issue here isn't simply a change in conditions between measurements.
