Yes the last time i used nano ledger s with ledger live it was fine. My concern was if i don't update it, would there be a time like when someone created a thread that they could not do a firmware update because they didn't touch their ledger in at least few years and was in that very old version like version one? That is why i always dont want to do an update.
Impossible to say with 100% certainty, but I would suspect that this would no longer be the case given the changes they've made to the firmware/infrastructure in more recent firmware revisions... I would think that Ledger would likely give warning if this was to occur.
The simple solution is simply check every 6 months or so to see if any updates have been released.
I thought i read 5 years somewhere. So that is the nano ledger x then right?
That would appear to be correct, from the Ledger Nano
X support pages regarding battery life:
End of life
The battery is designed to last 5 years. Ledger does not provide a battery replacement program. If battery capacity has degraded beyond being practically usable, the device can be used by connecting it to a power source using the USB cable.
As the Nano
S does not have a battery, so this "life expectancy" does not apply to the
S.

But you would never do firmware update if you dont have access to the phrase right?
That depends on:
1. Is it a "required" update?
2. How "urgent" the firmware update was (ie. is it patching a critical security flaw)
3. Whether I needed immediate access to the funds
4. The time frame for recovery should the device reset and I needed to use the recovery phrase
If it was super urgent and I really needed to use the funds, I'd probably risk an update without the phrase. For the most part, the newer updates seem to go through OK without requiring a reset. However, if it is just a "feature" update (providing new coin etc) and they're not features I desperately
need, then I'd probably just wait and continue to the current firmware.
As a side note... and something you might want to consider, given what appears to be a very large physical distance between your "regular" location and your recovery phrase storage location... what happens if you simply break the device and need access to your funds? What recovery plan do you have? Are you comfortable with the time frames involved?
It's all well and good having the recover phrase stored offsite... but useless if that is at direct odds with your requirements for being able to recover in a reasonable time frame.
