Backing up is a lifesaver in this case.
So, for example, you have a phone with 50 apps installed 3 email accounts and thousands of pictures. It's most likely that when they were testing the software upgrade on an older phone, that device was blank.
The best way to minimize the chances that something will get screwed up in the process is to backup your data and go for the fresh install. For most phones, you want to back that data up on a computer. For a computer, you want to save the data in cloud storage or a removable drive. After the new os has been installed then you simply import your old data and apps from the backup. This transition is much smoother than the quicker easy update.
Get rid of the "cruft."
There are other ways to speed up your phone like doing light maintenance. Over time your os accumulates all kinds of data. This leftover data is called "cruft" by IT experts. This cruft can seriously slow down your device.
On your phone or PC, you can download all kinds of apps designed to clean up your system. I personally use CCleaner. Mac users can install a program called Onyx or Windows users can run the built-in cleanup utility. For smartphones, you can open the settings controls and choose to reset settings. Just make sure you do a backup in case you lose important settings.
Pay attention to your storage.
Most people don't realize this but just because your phone has 64 gigs of storage space doesn't mean you should cram it full of files. As a general rule, the more storage you have free, the faster your device runs.
This is because you need that extra space so that data has wiggle room when you're moving files or downloading software upgrades. It's also keyed to the way storage works in modern devices.
Newer smartphones and laptops mostly use flash storage. The way flash storage works is by storing the data in scattered cells on semiconductor chips. Once the data is stored it's scattered all over the drive so when you are trying to access that data you are pulling it from all over the drive. If you have lots of space occupied, the data ends up being crowded and things slow down.
You should purchase more storage than you think you need.
Brian Denslow of TechCollective says: “If you fill these things up, it doesn’t get to operate as well. A good rule of thumb is to buy more storage than you think you will use. If you think you are going to use 64 gigabytes on an iPad, for example, buy the 256-gigabyte model."
I personally think you should take it one step farther by making use of the cloud storage that you receive with most devices these days. You can free up a ton of device space just by housing your photos to the cloud. This can free up several gigabytes worth of data and have your device running much faster.
