Hi! Is there someone on this board that after a full restore (DFU mode not resuming the backup) noticed major improvements on battery life or performance? Or is just a settings restore after a DFU enough? It is not yet clear. Some say that deleting a backup is useless, but according to others it actually dramatically improves one's battery life. Is it a legend or not? Thank you!
 
Do a regular iTunes > Restore and don't backup from an iCloud when prompted. DFU restore is for if you have a corrupt iOS install or unresponsive device and means nothing for what you are trying to accomplish. I have a 5s that an Apple Genius told me was "done with" because it could not hold a charge for more than a couple of hours and would always crash. I did a simple restore through iTunes and never put my stuff back on it and it runs much better. It's worth the effort if you have a phone that is slow/not holding battery charge.

It's well known that sometimes backup files contain bugs and issues from previous ios installs, older devices and other software conflicts. And those keep getting inherited back when using the same faulty backup file.
Restoring and setting up as new is always the first thing advised by Apple to start clean, remove bugs, battery probs and many other issues.

The problem is sometimes I saw some devices running 4 years old backups that were performing pretty much similarly to devices which had been restored. Plus, it's not possible to recover some data if you delete your backup. How can we be sure about this evidence ?

Are you using iCloud? You don't have to delete your backup. You just don't apply the backup when prompted after restoring. It will always be on iCloud if you ever need the backup and everything will be there, nothing deletes.

I don't get it. iCloud backups your phone as iTunes would. Isn't it the same thing? Or are you just talking about iCloud synchronization of contacts, mails, calendar ecc?

iCloud backs up everything on your iPhone like iTunes would, but doesn't require you to plug it into a computer and it is all available "on the cloud" rather than stuck on your computer. You could use either one, or you could use both, but iCloud is much easier to use and is faster than using iTunes.

you are never deleting any backup. You are simply not using some of the backup when you restore your phone. It will still be there if you ever need or want it. The things you will not put on your fresh restored iPhone are the things that make your phone slow such as app, safari, and system cache and settings that you've changed. Everything else can be redownloaded and reinstalled including mail, photos, apps, music,etc.

When you decide to restore your iPhone, you would start out by going to Settings > iCloud > Backup and Turning it On. You want to make sure everything that you would like to backup is switched on so that it saves. You can also go onto iTunes on you computer and backup your data there if you want 2 backups just in case. Once it's done backing up just go into iTunes and restore. Everything will be saved to iCloud and iTunes and you won't lose anything. once you get on your freshly restored iPhone, you can't "restore from iTunes/iCloud Backup" you have to "setup as new iPhone." Sign into iTunes and iCloud after that and your iPhone will be reattached to your AppleID. Then it's a matter of only syncing pictures, reinstalling music, and reinstalling apps, mail, etc.. Just make sure you are not restoring your iPhone from a previous backup and you will be good.

Thanks for your time and details, but this would not fix my problem, since I would loose the things that are included into the backup, like the app cache (I have some very important data on some apps), the pictures metadata, all of my messages, and something else...

Also, I've heard of people restoring without loading the backup and get an improvement, but getting worse again in one or two months.
