These are activities are blamed for iPhone storage full problem.

However, they are not necessarily the main culprit. Frankly, large video files cause not enough space on iPhone. According to Apple, iPhone introduces SE/6S/7 (Plus) with the support of 4K 30fps video recording to Apple lovers who pursue higher resolution. Now the latest iPhone even shoots footage with resolution up to 40 60fps. However, there is a problem. iPhone makes every picture crisp and sharp, but at the sacrifice of a large amount of data needed to store on iPhone, even with the newest HEVC supported to half file size for iPhone video compared with H.264. But this doesn't really take the strain off iPhone storage.
