A friend of mine recently went from an iPhone 6 to an iPhone 7 and is having much less battery life with the 7. The Apple store checked out the phone and said that since the 7's battery is smaller it doesn't last as long and that using data (like for calls), drains the battery faster. I'm having a hard time believing this. Apple specs show the 7 to have a much longer battery life across the board over the 6. So what gives?

That's Apple's crafty way of writing the specs. Actually, Apple says the iPhone 7 has "Up to 2 hours longer battery life than iPhone 6s", but it doesn't mention that the iPhone 6 battery in fact lasts longer than the iPhone 6s. "Across the board" therefore would mean across the current phones officially sold by Apple on its website.

So while the 7's battery may perform marginally better over the 6s, it may not better iPhone 6.
 
Here's my problem with the iPhone 7's battery. If I charge it to 100 percent before I go to bed and have it on standby for 8-9 hours I'll wake up with anywhere from 80-85 percent on average. I've owned every iPhone except the 6 and have never had this issue. With every other iPhone I'd at most lose 1 or 2 percent in that 8-9 hour standby period.

This is actually my second iPhone 7. I first bought one on launch day and had the exact same issue. I took it back one day prior to the 14 day return period and went back to the 6S(I'm on T-Mobile's jump on demand program btw). No issues with the new 6S but I started to get the itch to get the iPhone 7 again. So last week I walked into a T-Mobile store while at the mall and they had one in stock so I switched out my phone again. Now I have the same battery problem I had with the first one. I have an appointment at the genius bar on Friday night to see what they can figure out but does anyone here have any other thoughts as to what could be causing the issues other than a bad battery? I mean other than losing all that battery life while on standby the battery does pretty good.

FYI I just woke up a little while ago and my battery was fully charged when I went to sleep and it now shows 84 percent with 8hr47m of standby with 4 min of usage.

Something's not right. Did you check to see if any apps running in background are energy intensive?
 
Yep i checked that. I lose about 2 percent per hour in standby...sometimes a little worse. I'm gonna call Apple tomorrow night and see if they can fix the issue. If not I'll just go to my genius bar appointment on Friday.

That would be the best thing to do. The phone is indeed performing unexpectedly.
