Re: How often do you charge your phone?
 

Same. Although it was much better when I first got it - initially it would make it through even the longest day with 20-30% spare, now it ends up with <10% by 10pm even if I don't use it at all.

Z3 Compact on the other hand manages a minimum of two days moderate use, usually with 20-30% left at the end of the second day.

Overnight every night regardless of % left which is generally 40-60%. Never had battery issues with charging like this.

I charge my Nokia Lumia 930 overnight though it's usually still at 60%+ remaining after being off charge 16+ hours with medium usage anyway
