Generally no. Most phones will only charge at 500mA (about half of what a DC charger for a modern smartphone outputs) if it detects it is a USB port. The official standard sets USB 2.0 current levels at 500mA and 3.0 at 950mA. It is not uncommon for USB ports to support 1A or higher though, especially on laptops. The problem lies with the phones. Some ...

For a computer, there is a battery, usually a watch style circular one. This powers a small piece of memory traditionally called CMOS. This memory stores the time and all the other BIOS settings. On a modern PC these batteries tend to last way past the computers useful life time. A mobile phone/tablet isn't likely to have a secondary battery as they would ...

(CG)NAT doesn't actually mean you all have the same IP address. It means you have internal addresses which are translated to a shared address, just like NAT at home only translates private '192.168.x.x' addresses into the shared public one – but it doesn't literally assign the same IP address to every device. So that means the carrier can just look at the ...

Portable devices (like phones and media players) do not need, nor can they be, ejected before removing. That's why you won’t see a "Safely Remove" option in the tray menu. You might find this article useful. The relevant information from the article is that Windows gives Portable Devices special treatment. They do not have to be ejected / unmounted. If it ...

I've been trying to find an answer to the question at the top of this page, and so far have not found anyone who has actually measured things. Lots of people say "should" and "might" and "generally" but there is no actual answer. Having the equipment to do so, I did so. I measured the voltage and current coming from my USB power source (more on that later)...

TCP and HTTP are different things. TCP is the transport layer. By definition, it's responsible for carrying application layer protocols (HTTP in your case) over it. TCP does not run over a port. It is the arbitrator of ports. In other words, when you connect to an HTTP server, you connect on TCP port 80. When you connect to HTTPS, you're connecting ...

Found the solution here. They moved it to "History -> Show Full History". I guess it isn't used very often.

The Inspirons have a magnetic catch for when you close the laptop lid. They use the magnetic sensor to work out when the lid is closed so the screen no longer needs to be on. Your phone is triggering the sensor.

The reason is security. SIM card is not just an ordinary piece of read-only memory. It's a separate micro-computer with its own environment capable of running Java Card applets. They can communicate with network provider and he can modify them over the air to some extent. For example when you want to change network provider, but keep your old phone number, ...

If you are browsing using your operator's network (and not Wi-Fi) they could just check which company owns the IP address that you are assigned when accessing the site. It's pretty easy to do. Click on this to get information about the IP address you are using. As you can see it tells you which company actually uses the IP address in the host section.

Some GSM operators are using "NFC SIM" term to refer to a SIM card with an additional financial application. Such a card in combination with a NFC phone can be used for contactless payments. There are different options: it can act as a pre-paid debit card your payments are added to your GSM bill you can open an account in a bank partnering with the GSM ...

If I understand your question correctly, I might rephrase it as, "If the network infrastructure allows HTTP traffic to pass on a certain port, will it also allow pure TCP (without full HTTP-compliant operation or even fake HTTP headers) to pass on that port?" Unfortunately, the answer is, "It depends on details you have not yet discovered regarding how the ...

Some additions to the other answers: Channel Number: Since you are using an Android phone (Sony Xperia P), I suggest you install the WiFi Analyzer app from the Play Store.

The Oversimplified Principle Of Battery Charging Assuming you know the following: The input power, in Watts, that your power supply / charger is capable of supplying to your laptop The power, in Watts, that your laptop is draining while it is running (assuming you have it running; otherwise this is very close to or equal to 0 Watts) The power, in Watts, ...

Practical Answer "it depends" on how your hold your phone, the layout of the space you're in, how many walls, what's in the walls, etc. Unfortunately, the real-life answer is to just boost the AP power and see if you can connect, and if you can connect some speed-test data to quantify how well you're connected. For example, you may get a useful ...

Wireshark or any other 802.11 monitor mode packet capture tool will let you tune each of the different Wi-Fi channels and try to capture packets from any device transmitting on that channel. These transmissions almost always contain the MAC address of transmitting device. Wi-Fi client devices, when not connected to any network, will periodically scan to ...

What do the APN settings on the phone actually do? The APN settings contain information required to set up an internet data connection while you are on a mobile network (that is, not connected to wifi). In regards to the access point name and the primary proxy server, What exactly happens when I tell Safari to load a webpage? Most of the magic of APN ...

I find lsusb easier and faster to use in such situations.

2,4 is the frequency, b/g/n is the standard. The "best" connection is guaranteed with N because it is the newest standard. This is the IEEE standard 802.11n which supports up to 150Mbit/s!

The answer to the question in your title is yes. Screenshots will almost always be smaller than a camera image. Take the iPhone 6 as an example. The screen size is 1334x750 pixels. The camera can take images up to 3264x2448 pixels. There are 8 times more pixels from the camera than from the screen. Screenshots are generally stored as PNG files (on Android ...

The issue of loss of capacity with battery charging and discharging is due to crystallization of pure concentrated chemicals inside the battery. Once crystals start to form they do not want to revert back to a liquid state again, and the battery permanently loses some charge/discharge capacity. This is why sometimes old lead-acid batteries bulge outward ...

In the 70's and early 80's: RAM was very very expensive it ran at the same speed as the CPU. programming by hand in assembly language was common So - simplifying very much here - it made sense to design CPUs where each instruction performed a lot of work, was easy to translate from high-level languages, and where programs were expected to use memory as a ...

If this model supports transferring contacts via Bluetooth, and you have a Bluetooth adapter for your PC, you could transfer them there, and then convert them to a format Outlook wants (.vcf, I believe). On feature phones such as the one you have, the contacts are not designed to be extractible by the consumer. There is no way to download them directly to ...

There are all sorts of conditions than can affect this, but as a general rule of thumb, the faster you charge/discharge a battery, the more you will 'strain' it (lowering lifetime). Again, not always true, but as a general rule of thumb your wall charger will deliver more current than your PCs USB port, charging your battery faster. Therefore, the ...

The easiest way to do that is replacing the phone's motherboard. It will have a different IMEI. If you buy a busted phone, the LCD may be the only thing wrong with it and you could possibly use that motherboard, though try to inspect it before you buy it. I think it's possible to change the IMEI reported by the phone to any one you want - possibly by ...

1) Yes there is. The mobile provider needs to know where your phone (or rather, near which transmission tower your phone is) so they can send incoming phone calls to you. No internet is needed. 2) Nobody can track anything using GPS. GPS is receive only. 3) Please read or FAQ helpcenter to see what is on-topic and off-topic. You can find it at the top of ...
