Downloading large files into your mobile phone may seem convenient and fast, but it can also have some disadvantages that you should be aware of.

 Here are some of them:

  • It can consume a lot of your mobile data plan. Depending on the file size and your network's speed, you may end up using more data than you expected or planned. This can result in extra charges or reduced speed for the rest of the month. (source:
  • It can take up a lot of your phone's storage space. Large files can occupy much of your phone's memory, leaving less room for other apps, photos, videos, music, and documents. This can affect the performance and functionality of your phone, as well as make it harder to back up or transfer your data. (source:
  • It can expose your phone to security risks. Downloading files from unknown or untrusted sources can introduce malware, viruses, or spyware into your phone. These can harm your phone's system, steal your personal information, or compromise your privacy. You should always scan the files before opening them and only download them from reputable websites or apps. (source:
  • It can drain your phone's battery. Downloading large files requires a lot of power from your phone's battery, especially if you are using a cellular network or Wi-Fi. This can shorten the battery life and make your phone run out of juice faster. You should always plug in your phone while downloading large files or use a power bank to avoid running out of power.

You download a file from let's say iCloud with a file size of 128 MB. 

  • This file size is equivalent to an average of 50 pictures/images that you could otherwise use to take selfies/pictures.
  • Multiply that by how many times you download the file to view just one page of the file.
  • Each downloaded file remains on your phone until you manually delete it.
