I was wondering if you have a very full storage capacity of your iPhone or iPad, will it make your iPhones battery last a shorter amount of time. Or, if you have used a very low amount of your storage, will your battery last longer? I ask this because my iPad is nearly full and it does feel like it runs down kind of quick sometimes. But my iPhone seems to last a long time and it is less than halfway full of storage capacity. With my iPod touch, It was completely full and the battery was terrible, when I removed a ton of apps, I got the storage down to half, and the battery lasts longer.
