I agree, the battery life is shockingly poor. I blame touchwiz as much as anything else. I would take a slightly thicker phone for a battery that consistently lasts all day.
Samsung TouchWiz with KitKat 4.4.4 had awesome performance and battery life on my Note4, then they destroyed it with a Lollipop update (after constant update nags) and forced me to downgrade probably voiding my warranty in the process, anyone sane would have returned the phone. I don't know if Samsung or Google is to blame for the serious battery and performance regressions, but I do blame Samsung for pushing it out to its users. Many people have been burned by this and will never buy Samsung again. What were they thinking? It's not as if Lollipop offers anything much for the average user (developers are another matter). It's such a shame, as the hardware is top notch.
Well we shouldn't need huge batteries if Android was fixed. Have you seen the batteries Apple put inside iPhones? iOS is great for their hardware margins.
Note 4 is a 5.7" screen. There's plenty of room for Samsung to ship a high capacity battery. The Blu Studio Energy is only a 5" but has 5000mAh. If reviewers started giving out bad reviews to anything that can't last a 24h day, other OEMs would fall in line.
i have my s6 rooted and with a custom rom. battery is not as bad, but not amazing. if i'm on a place with good mobile signal and on wifi, i can get a day[0] of battery life with ~2h of SOT (with my pebble connected and syncing all day long).
but at the same time it's kind of worth it, because it's easily the best camera on a cellphone i've ever used.
That's the biggest difference. The main thing I've noticed (I've owned, in order a Moto Droid, iPhone 4s, HTC One m7, and now an iphone 6s+) is that battery life during USAGE is broadly similar, but iPhone uses a HUGE amount less when sleeping/idle.
I swapped an iPhone 6 for an S6 so I could run a GearVR, which is fantastic. The rest of the Android experience is surprisingly not bad, and Google Now is notably better than Siri.
What about the new battery saving features and all in the new Marshmallow upgrade?
Also, Nexus 6P (with the usb 3.1 type C) can get fully charged in under 10 minutes. I've heard that it's possible to get days worth of usage with just like 8 or 9 minutes of charging. That sounds pretty nifty.
