IPhone storage space doesn't add up?

So my iPhone has a total of about 5.4GB space to use. My phone says I have no space left 0MB. So obviously I deleted an app which used up 167MB. I delete this app and then refresh and it says 24MB available. So I'm thinking okay, its probably just taking time to clear up the space if i keep on refreshing it will show it all eventually, right? As i keep refreshing I notice the space is getting smaller and smaller like 24MB then 15MB, 6.4MB and the 0MB and it's all gone!

This has been happening for the whole of December now. I've deleted about 600 photos, a few long videos, all my apps (I only have Snapchat and Instagram left?!). Everytime it shows that I have cleared out the space just like normal but it never gives me my space. If something like this has happened to you please say what you did. Thanks xx IPhone storage space doesn t add up - 1

Do I always have to buy songs from the iTunes store?

I'm going to buy an iPhone and I'm an android user. I was wondering if I will always have to 'buy' songs from the store or can I download it or transfer it too? Please help. Is there a different method of adding songs to your IPhone?

Used iphone or a new blackberry? (temporary)?

Its been like 4 month for me without a phone… Since i broke my old note 2… And its actually been 3 years since i've upgraded… And i need an iphone 6s (64gb) really badly! But i can't get it before this coming summer… So am stuck with 2 choices till then… My dad is offering me his old iphone6 (16gb) for 165$ its in good condition to be honest but i personally hate used phones… Or i could buy a temporary blackberry q10 with the same 165$(not a blackberry fan)
it could be a stupid sitiuation but i really donno what to chose temporary until i could get my iphone 6s

I have the iphone 6 plus and have been trying to sync music from my pc which is also an apple product but when i plug it in iphoto automatically opens up but its not recognizing itunes.

How to start fresh with a new iPhone when I already had an existing apple id?

I'm purchasing a new iPhone 6s Plus and right now, I have an iPhone 5s that is hooked up to my mac computer (with an apple id, iPhoto, iTunes account and icloud). I want to start fresh with my new phone and delete my apple id, Icloud, iTunes, iPhoto and create a new apple id and everything for my new phone but I'm not sure how to do that. I don't know where to start or how to get rid of my iCloud emails that are signed into everything on my computer, my iTunes, my iPhoto and my apple id. I want to create a new apple id and all that for my new phone so that I can start fresh and keep my phone new and clean but I'm afraid to plug it into my mac when the phone arrives because I fear that all of my old stuff from my iPhone 5s will sink onto my iPhone 6s plus.

Got a replacement Iphone 5s and battery might be defective?

Last week before I went to bed, I put my iPhone 5s on the charger and it was fine. When I woke up the next day, I went to unplug it and my phone was off and I tried everything to turn it on and it didn't work so Tmobile sent me another iPhone 5s for free since I'm still under warranty. I backed it up from iCloud but it only saved stuff from a year ago and couldn't back it up from my iTunes at the time because I didn't have my laptop with me since I was in work. I went to charge it and it said it was charging but the battery percentage wasn't going up. Is it because the battery is effective or maybe because I didn't update it with the right software? This is so inconvenient for me right now and don't have the time to runaround to Tmobile to get a replacement phone that was supposed to work since it is the phone to replace my broken one in the first place. Somebody please help me lol

Best iPhone 5s Glass Screen Protector?

Just got new iPhone 5s and have a glass screen protector on it currently, however, I'm looking for a glass screen protector that gets the job done but also has a warranty so if it breaks I don't have to break the bank trying to buy a replacement protector. Preferred rounded edges so it won't chip as easily.
