Ditto, followed by a Galaxy S4.
Removable batteries have been a huge pro for me, I am often very hard on battery using bluetooth and playing media for 12 hours at a time away from charger.
Really other than being a little tall the battery is what is keeping me away from the M8.
What options does a guy have to combat a non replaceable battery?
Probably no options are needed. I used to carry a spare battery (or two!) for my T-Bolt but found I could live with the S3 and S4 batteries by keeping a spare battery on a charger and swapping batteries around 6 PM each day.
I was VERY nervous about going to the M8 with the non-removable battery but it lasts and lasts and lasts....... I take it off the charger at 7 AM when I get up and have more than 50% when I go to bed, usually around midnight.
I have a car charger, never needed to use it, I have a USB cord plugged into my PC so I can charge while I'm typing this, never do though, it's not needed.
I can't speak to battery life 3 years down the road when cell phone batteries start losing life but in 3 years I suspect this phone will be as obsolete as a rotary dial phone is now and I'll be looking for the latest gee-whiz phone that is cosmic ray powered or ????
Don't worry about the battery, it'll be fine.
FWIW, rooted, TWRP recovery, running BoneStock ROM (thanks, AndyBones!) with power saver turned OFF!
