    Hey guys

    At night I leave my iPhone on DND and also low power mode. I normally sleep 12AM - 7.30AM and when I wake us I notice that my phone has drained 5% over night exactly. Is this too much? What do you think is draining it? You'd think it would hardly use anything with it being on standby and also low power mode.

    IPhone 6S Plus 64GB - Samsung A9
    Running iOS 9.1 B5

    If you leave it on wifi or mobile internet then this is quite normal on any phone.

    5% is bad? thats normal for me

    sometimes it's 8/9 %

    hell my S6 edge used to drain like 11% overnight

    I get loads of twitter notifications during the night in fairness and will get even more when the NBA season starts

    So my experience w/ battery life for the first couple of days has been underwhelming, but today I'm trying an experiment to see for how long it will play streamed music (with the screen off throughout) before the battery goes out. 6 hours in (5.5 = 802.11ac, 0.5 = LTE), it's at 85%, meaning that it should be able to keep going for 46 hrs total. I guess that's not too shabby considering the 80 hr figure determined by Apple involves local media, not streamed.

    The battery is reported to hold .3% over design capacity. Mega-drainage appears to kick into high gear when pixels are being shuffled around... that's when my 6s Plus behaves like it had a 5s battery. Forget "12 hrs internet use", think 4(ish).

    Not placing the blame on the Samsung chip just yet (ahem) but maybe, just maaaaayyyybe this has something to do with the Samsung-made embedded M9 vs iOS 9...?

    5% overnight? That's normal ... As a matter of fact anything 10% and under could be considered quite normal. The iPhone 6 Plus and 6s Plus both have great battery life anyway...

    I don't put my phone in low power mode or turn on DND overnight. If I go to bed with it at 100% charge, when I wake up it's usually at 99%, but I've seen it at 100% a couple times (and I also have the Samsung chip so let's not go blaming that! :p ). 64 gb 6S+.

    I consistently get over 9 hours of web browsing from my 6S+, and that's whilst doing additional tasks all day long like taking calls, using apps and sending SMS. The quoted stats of up to 11 hours of WiFi/LTE browsing is spot on.

    As for overnight losses, it all depends on your settings. If you have emails fetching or pushing, notifications, backups occurring etc. I put my phone into airplane mode at bedtime and lose nothing, or a max of 1%.

    Mine doesn't drop from 100% overnight. This was with charging overnight. I always have wifi and wifi calling on. I do have battery draining options turned off, like background refresh, auto updates, Hey Siri, Spotlight search Siri suggestions, Auto brightness, Location Services off on most apps, etc.

    I haven't seen a drop of even 1% (from 100%), yet (other than the single time my phone was acting up).

    They have these really cool things called chargers. You can put one right next to your bed. Problem solved.

    Well, technically it does drop... it has to. "100%" is a white lie on both Macs and iOS devices, as you can easily verify w/ Coconut (which now gives you complete battery info about any USB-connected iOS device). The precise reading can drop to 98% or even less before the "official" indicator starts reading less than 100%.

    Heh, yeah. Mine drops to about 95-96% overnight but then again I have most of the "known culprits" activated, various push notifications, checking 5 email accounts etc. My focus is on using this thing the way I want to, not disable functionality in order to keep some number as high as possible. ;)

    I have the 6S plus 64 GB sim free with Samsung Chip, was in wireless inductive charger. Woke up, still at 100% with 2 hours and 30 minute usage time, standby time 7 hours. :cool:

    Clearly something was running in the background while screen was off. But still good battery life.

    My 6S Plus has more battery left over at the end of the day than my Galaxy S6 Edge+. At bedtime, my 6S Plus still has around 50% compared to my Galaxy S6 Edge+ which usually hovered around 35%.
