Where is this magical iPhone 6 Plus battery life?

Same here. I am not finding that my iPhone 6 Plus has particularly long battery life. In fact, it seems to be only marginally better than my iPhone 6, but I haven't done any scientific testing to verify that. I have reset all settings on my 6 Plus to make sure that there is no battery drain.

I stream music over wifi for 10 hours a day at work while using a few chat apps occasionally, then i spend the next 4 hours after work using it looking at youtube, google+, and my chat apps and i have 30 to 40% battery left after 15 hours of use.

im getting 15-16 hours of use on my 6plus

you might try a battery calibrations - (let the battery discharge all the way until the iPhone powers off then charge it back up to 100% and leave it on the charger for a couple more hours

its also possible that battery life will get better after a few charge cycles

if it doesnt you could try restoring the phone as new - and not doing a restore from backup or adding any of your apps back and see if that helps - you could have a corrupted backup or an app thats draining the battery in the background

Finally you could take it to Apple store (with a genius appointment) if one is nearby - it could be a defective battery

how long have you had the phone? - battery usage tends to improve after a few charges - you might want to wait a week or so and see if it gets better before restoring it

I had the same problem on my 5s. It's a real pain

you have something running in the background or maybe some email accounts that fetch new emails too often? My phone loses no battery during a 6 hour sleep, although i have most things turned off.

Absolutely no improvement whatsoever.

Only difference is that it literally takes 2-3x longer to charge. Making you think you've got this far more robust battery to fill.

But then its pushing 20% and 10% just as fast as my 5s did ...

Fail

if you are near an Apple store i would make an genius appointment to have the battery checked - if not you can call Apple iPhone support and see if they can help - they may have the ability to run diagnostics remotely

Very strange. I have most all features on and if I leave my phone off the charger overnight, I'll lose only 3 - 4% charge by morning. I have no problem whatsoever getting a full day out of the phone with lots of wifi music streaming, some moderate video, lots of email and surfing.

my iphone 6 plus is by far the absolute worst battery life of any phone i've ever owned. I brought my phone into apple store genius bar and showed them like 50 screen shots of my battery usage screen saying i lost like 50% over the course of a few hours of extremely light use. They basically told me "our battery diagnostic app says yur battery is fine... go away.'

I've tried that let it die down to zero percent and then recharge thing like twice. It does nothing. Apple refuses to acknowledge that my iphone6 plus has a garbage battery. I do not trust their battery diagnostics test as far as i can throw this 1000 dollar paperweight and that is basically what this phone has been since the second i owned it,

THis is NOT A TROLL post. I am a 100% genuine iphone 6 plus owner who truly is unsatisfied with my purchase. This is truly 100% without a shadow of a doubt the worst battery ive ever seen on any smartphone ever and at the same time i acknowledge that there exists ip6+s with great battery life. There has to be some super dodgey stuff going on like there are just tooooo many bad batches or something. Maybe my phone was part of some rushed batch to make it in time for christmas and they were careless n heavy handed at the factory something i dunno but what i do know is my iphone 6 plus has absolutely dismal, pathetic and downright makes the phone unusable when i am out and about due to battery anxiety.

There are way too many posts of people saying their ip6 battery is bad while other posts saying it's good. It's starting to become apparent that the iphone 6 is just extremely inconsistent and quite frankly not worth the risk really. You could get lucky n get a good 1 but you could very well get 1 like i have that literally died down from a full 100% charge down to fully dead in less than a half a day from literally zero use whatsoever. it just sat there sleeping. I didn't use it during this. It was a test to see how long it would take to die and it failed this test miserably and yet apple's useless little battery diagnostic over at genius says my battery is just fine n dandy... yeah right. Its crap. The genius dood who was totally cool n he's just doing his job/ protocol or whatever no knock to him but he just pointed me to some battery conversation tip link on apple's website and sent me on my way. I showed him screenshot after screenshot showing extremely poor battery life math and he just wasn't interested in hearing of any of it cause his all knowing battery diagnostic thingy infront of him is some all knowing crystal ball says my battery is fine and that's the end of it and the piles of screenshots i have saying my battery is dying 10 times faster than your are claiming while i had no background apps or anything whatsoever running don't mean a thing.

I want my money back apple . Your product does not perform as advertised.

When you check the Battery Usage in Settings>General>Usage, what are the Usage and Standby Times? What apps are the top five battery drains in the last 24 hours/7 days?
