Probably because she is constantly on it.
Exactly. If true at all, she's still in "new toy" mode. My wife got hers 3 days after launch and is still glued to her phone. New 3d touch gestures to figure out and features to dig through. She hasn't even used the camera yet, still much to dig through. Yet she gets through a day, no problem. She actually has to change her behavior, she docks her phone as soon as she gets home like a reflex, but doesn't really have to until bedtime. The s6 edge has horrible battery life - debloated, I leave the house to commute at 7:30 am (an hour of heavy use on Spotify and candy crush, on standby the rest of the time) and by 11:30 I'm at 50%. The iPhone trounces that, there's no competition. I've had better luck with the moto g (a great buy if you ask me), but to specifically say that the s6 has better battery life than the iPhone 6s, well, that's just not true and documented.
I figured out why the android apologists bug me, they remind me of the relatives who insist gay marriage is wrong JUST BECAUSE they feel it's so. Or the gun nuts. Or the ones who insist solar's not worth the research even though more research is bringing efficiency and costs down to coal levels (now, imagine in 10 years). Alternative energy's a crock of shit to them JUST BECAUSE THEY REALLY FEEL IT. I'm not doing a good job explaining the connection, but there's this woeful ignorance mixed with anecdotal evidence, driven home with an arrogant "I say so, so it must be right, you're a sheep (hippie)!" that just rubs me so wrong.
Hell, I like android, just s6 edge costing flagships simply don't make sense at the $800 level anymore.. ANd I think we have a lot of people hiding buyers remorse with indignant, misinformed arguing. I guess it keeps the forum a lively place. I'm sticking to android below $300 (tablets for the win) and ios for flagship phones. Who really gives a shit what phones people have, but let's not just lie. It makes research harder on people. It's why I got the s6, people raved about the battery life on forums but probably just loved Samsung and didn't even own the phone yet.
