S5 has two types of Battery saving modes,
I never use them in my ordinary days but when I was Hiking I had the S5 on Ultra Power Saving Mode and It would last for 8-14 days (I switched between modes so cant really say) (but then again, it also renders the phone unusable in terms of functionality (you can text/browse the web and take calls) and also everything is in black and white. but you cant take photos or record video which is what I wanted todo..
the second normal powersaving mode just limits to one core being used so its abit lagish at times but nothing you will get irritated about as the normal mode is smooth as butter..
So I have had mine for about 6 months now,
been using it quite alot today, Browsing around/imguring taking calls and listening to spotify for about an hour. no saving mode or anything and the battery is at 53% thats (Unplugged from 07:30 Morning to 00:40 Midnight)
which is totally fine by me, usually my phones would dry out about the same usage before..
so thats my report on the S5
ps, yeah happy new year
