Nexus 4 battery problem

The other day my Google Nexus 4 phone had a battery charging problem. I put the phone on charge with 43% remaining and after a few hours maybe up to 5 the charge was only up to 45%. Taking it off charge and looking at the usage it dropped back down to 44% within a minute. I thought I was in trouble and there was a physical problem with the battery. The solution was to completely turn off the phone and switch it back on, then it started charging fine and I've had no problems since. The only thing I can think of that could have caused a problem is either the number of apps running or a specific app that causes a problem, will keep an eye on it.

The Nexus is not great when it comes to keeping its battery power and I have to charge mine on a daily basis. Here are some tips on improving the charge of the battery.

• Switch the NFC and Bluetooth off when you don't need it.
• Turn off App syncing when you don't need the App to be synced.
• I've chosen a dark background to try to reduce brightness.
• Apps that have the option to change the background colour I've set to black.
• Check the battery usage and see what areas could be improved.

Using iPad / iPhone as remote mouse

Recently I have been doing some development work on the iPad and iPhone, while doing this I started thinking of ideas for my own App. One of the ideas was that the iPad touch screen works very similar to my MacBook's trackpad, but is larger, so I thought it would be great to be able to use my iPad as the trackpad for my MacBook, my first thought was how it would communicate between the devices and I thought Bluetooth was the solution. Someone has already beaten me to this idea and come up with an App that does this, it is called 'Remote Mouse', if you do a search in the App Store you will find it. You will also need to go to their web site and download the software that needs to be installed on the computer, it can also be installed on a PC. It does not use Bluetooth but uses WiFi, it is a clever app and I am glad I did not spend much time looking into developing one.
