Hi guys , I was an iphone 1 user years ago. Switched to jet > s2 > note 2 then swapped it with my brother's iphone 5. The note 2 is a good device but it's just too big for me , I'm having a problem carrying it in my pocket and I think I just wanted to try it and not totally "use" what's it's intended for. Since I also have an air and another tablet. What I miss about it though is the back , home and menu buttons. Anyways so I did a factory reset on the iphone5. Installed some applications here and there. I noticed the wifi turns on/off frequently and it's really irritating. On my note 2 I didn't encounter any of these problems. My air is connected to the wifi as well and it didn't lose the connection. I thought maybe my brother is downloading someting in his laptop, he's 2 other phones are connected via wifi as well. Few hours later , I tried removing the spigen bumper ( the black one ) to give it a try. And wifi works well without disconnecting. Installed the bumper again and it's fine now. Not sure what could have caused it, brother downloading files or is this a software issue ? Any applications you can recommend ? What is the difference between reset settings in the iphone settings ( erase all content and settings ) and using itunes restore option? In the android there's an application called airdroid were you can transfer files via wifi , is there's a similar app on the iphone? How long does the battery last ?
