Re: Upgrading OS 4 to 5- for Begineer
And please do not write in text-speak.
Battery life depends on use. One day is generally considered pretty good. Just don't let the battery get below 20% more than a few times or you will damage it and will have to replace it. LI batteries like to be kept topped off when you are near power.
I cannot say how your device will be affected by OS 5. I always had 4.6 on my 9000 and it worked well, did what I wanted it to do.
