Some questions about battery and system

[Ivan S]

Hi, I forgot to change for Ativ S before starting using it.
Is it OK for my battery ? (I also noticed that battery was charged 300 (!) days ago before I turned on the device)

What is the usual life time?

And the next question.. is there any way to enable strong passwords on the lock screen?

Hmm. I'd recommend that you go through at least one charge cycle to make sure the battery is up to snuff.
If you define life time as how long the phone lasts on one charge, it should be around a day with moderate usage (*my definition used), with enough juice to last a night.

As for strong passwords, if you define these as alphanumeric combinations, nope.
