I bought my iPhone 4S (16G) two years ago, I found it became slowly now. I have about 10G Photo and video in it, if my iPhone becam slowly caused by my large Photo video storage ? How to speed up my iPhone? if i must delet my photo?
Since the OS takes up 7-8G, my first thought would be that the amount of pictures and videos can certainly have a negative impact on how the phone is running. I would start by backing some of your photos and videos up to your computer. Make sure you're running the latest iOS version 7.1.1 as there were some improvements made for performance in that last update.
Thank you. I have backed up my photos and videos to my pc via some software. And i upgraded my iOS to the lastest version 7.1.1. My iPhone 4S is faster now.
I'd say that iOS 7 is the main cause for iPhone 4S being painfully slow. Maybe the latest iOS 7 version fixes some of that. Clean up some temporary cached files, often those tend to clog up the iPhone and slow it down: How to speed up iPhone and clean up unnecessary files with CopyTrans Apps
