Hi,

i just bought an iphone 7. I don't now if iOS 11.3 is better than iOS 12 ?

I need:
-best battery life
-want to jailbreak in future maybe...
-best performance in UI and web browsing, no gaming at all

Thank you!

iOS 11.3 is jailbreakable using Electra. Jailbreaking has become semi-tethered which requires to run the tool every time the device restarts.

https://coolstar.org/electra/

If you were to update, iOS 12.1.1 is the lowest signing firmware. Jailbreak for that build is unknown at the moment but possible for earlier version iOS 12 because of a patched bug.

Best possible battery life may be on iOS 11 but best performance on iOS 12. Best jailbreak version on iOS 11 until iOS 12 patched exploits can be used to develop a jailbreak.

Updating to iOS 12 will prevent you to downgrade in the future because older firmware are not signed anymore by Apple unless you restore using IPSW firmware and shsh blobs to current build version.

I’m no longer in the jailbreak scene and I value security and performance so I would update.

Thank you, i think for now i don't need to jailbreak, maybe the only thing i miss is the GPS Toggle and Wifi (24/24h off)

And i'm afraid of being stuck with an iOS without SHSH, now i can update to 12.1.2 and save the SHSH ? And if maybe iOS 13 or iOS 14 make my phone unusable (stutter, lag etc..) i could downgrade only with the SHSH ?

If you want to jailbreak, you answered your own question.. In my opinion, iOS12 is better than any version of iOS11 if you want to run stock iOS..

Ok, i did the update to 12.1.1 not 12.1.2. Because i was afraid of the issue with wifi/cellular . And finally i had a problem with sharing 4G with USB!! Now it's OK, i hope it will be good, i saved my shsh/blobs in case for future update!
