At least for me I’m not finding that to be the case. Each year I upgrade to the next version (always aluminum & space gray) so right now I have the 6 & the 5 on hand. One is always charging, and I swap them out every 24 hours or so. They work well for me through the days & the nights. Next month I’ll purchase a 7 & trade in my 5.What about better battery life? The battery life desperately needs the attention.
