True I noticed that too on my previous iPhone 6S, battery life easily lasted me 2 days on the iPhone 6s, mind you , I was lucky to get the iPhone 6S with the TSMC chip not the Samsung CPU, the TSMC variant runs much cooler and has 15% more battery life than the Samsung variant of the iPhone 6S
This matches my experience with both a Note 4 and Note 5 in comparison to the iPhone 6s Plus. People don't want to believe how fantastic the battery life is on an iPhone 6s Plus. Oh well, doesn't matter to me. I've done the Android thing for 3 years and I am sick of many aspects of Android life. So, I gave the iPhone and spin and I am happy. No this doesn't matter to others, but it matters to me. I shouldn't have to use battery packs and car chargers and I don't now. Yeah the customization on Android is great, no doubt about that. However, that just isn't what is important to me. I want a full days use, not having to tweak this or turn this off. I want to just use it and let the phone handle the rest. I've never gotten that experience with Android. Though it hasn't been all bad and for those that the Android works... GREAT that's what makes the world go round.... choice!
there is no fast charging, takes freakin' 4 hours to a fufll charge.
Yeah and I do that overnight while I am sleeping and I've yet to EVER need to charge during the day considering I end my day with about 40% battery life. So that is a moot point!
