Mobile Development Digest #58

Finally, Samsung defined list of problems which lead to explosion problem with Note 7. It’s remarkable attitude to problem detection and I really glad to see this way of presenting what and how was done. Especially in comparison to Apple who do not want to do anything with batteries behavior on cold. Literally, I cannot use  my iPhone 6S Plus on the street now more than 10 minutes.

Last week new Accidental  Tech Podcast was released and it’s good to listen if you still curious about Chris Lattner transition from Apple to Tesla, he gave short interview there.

The Case for Deprecating UITableView. In my recent project I had a chance to compare how Android’s recycle view and iOS UITableView works. Now I had strong feeling that for dynamic design it’s better to avoid UITableView use. It’s not bad but it’s too old and this affects it’s API and architecture. UICollectionView looks like a good replacements for UITableView.

On the other hand, in many cases you do not need any framework, but you may use benefits of open source to get fresh ideas about visual representation and code architecture.

  1. iPhones are rated for use from 0°C. So if you use it at lower temperatures, we’ll, it’s a mistake.
    Furthermore batteries are working with chemical reactions and low temperatures are slowing down reactions so it is never good to expose any battery to cold. Same thing goes for heat which can damage the battery and the device around it.
    So never leave your phone in your outside pocket of your jacket or in a purse when it’s cold. A much better choice is closer to your body (like your pants).

    1. True, but iPhone 5 and Nexus 6 works fine in the same conditions. So, I believe that nature of the battery is not the only one reason of this.

      Keep it close to body is the right thing, but sometimes I want to use phone for making photos or to call someone. Currently, I have the short period of time before my phone will be turned off even if I have 50+ percent of the battery.
