I had the same issue as the other people in this thread. My iPhone 7 would drop about 3% an hour on standby. My last phone, a 6s Plus, had fantastic standby battery life and I'd get about 9 hours of usage. Went to the Apple Store, got a Genius who understood there was something definitely not right. He did a diagnostic on the battery and found nothing as I expected. I told him that I'd already reset the phone multiple times and put it into the DFU mode thingy which didn't fix it. He said he wanted to completely rule out software as being an issue and so he reset the phone and put some different version of iOS on it (I didn't really understand this, he said something about how our phones get the software from different servers or something like that). He had written down notes of my problem and told me to come in again if what he did didn't fix the issue and I'd get a replacement iPhone.

The issue was not fixed.

Five days later I went in again and got a different employee who I explained the issue to and how the last guy told me to come in again and they'd replace my phone. This guy didn't seem interested in what I was told five days ago and instead tried to school me on how iPhones work and that the standby battery drain was normal because the phones are "so powerful" he said. I sat patiently and listened to his spiel but then reminded him of what I was told by the last employee. He went off for about 10 minutes and came back to tell me that I would get a replacement iPhone because that's what I'd been promised. I got the feeling he wasn't happy and that he'd rather send me off thinking he'd educated me.

My replacement works perfectly and I now get similar battery life to my old 6s Plus.

This really shows that it all depends on who you get at the Genius Bar. If I had gotten the second guy on my first visit, I would still be stuck with a defective phone. Good luck, guys.

Glad you managed to get a non-affected phone. Do you mind sharing your results? I had the same battery drain issues and got an exchange last week at the Apple Store. I wasn't satisfied first and decided to do a DFU / restore with iTunes 2 days ago. I went to bed with 80% remaining and woke up 9 hours later with 76% (Wifi ON, BT OFF). Not bad at all, given that I would typically lose around 15% on my previous phone. Phone was set up as new, currently using default settings, haven't installed any apps yet other than LinkedIn and a few games.

I'm more impressed and envious of you getting nine hours' sleep.

Yep, I went through 3 guys and all three tried to explain me the drain was "normal". At least the 3rd guy agreed to do some further testing on it and I assume either finally agreed when he saw that it was draining with nothing installed in even airplane mode like it was was not "normal" or just gave up arguing with me and authorized a replacement.
 
VZ iPhone 7 80% battery after 30 hours into a true standby ie not really using the phone

Bluetooth is off and connected to wifi
 
Well, last Saturday I got a replacement for my iPhone 7. After 2 visits to the Genius Bar and a call to Apple Support, I went to the store a third time and they agreed to replace the phone. But not without tell me that maybe this was not the solution.

For now it seems that it is the solution because in airplane mode only drain 2-3% not like the other phone that was about 20% of battery.

So, third time's the charm.
 
Something I noticed was how I downloaded a battery statistics app and it said I had 1715mah, and my battery life was doing awful. I did a restore by updating software from iTunes instead of over the air. Now it's saying 2000mah capacity, which is what my iPhone 7 should approximately be. And now I get 8-10 hours usage.
 
hi all. I am having all sorts with the battery life on my new 7. I cannot get a full day without recharging. I could easily get a day with my old 6 but the 7 evens loses battery when turned off overnight. Anyone else having issues ?
 
Doesn't seem anything out of the ordinary in your battery usage. Have you tried a hard reset?
 
disable background app refresh entirely-

I have background app refresh turned on for all apps and get 10-12 hours of usage out of 7+. Having background app refresh turned on doesn't mean apps can refresh data all day long. There is a logic set in place for this feature.

For example let's say every morning at 8AM as part of your morning routine you check your favorite news app to see what is going on in the world. After some time iOS learns that you open this app on a daily basis around the same time and in anticipation it will refresh the data right before 8AM so when you go to the app it's the most recent news and you don't have to press refresh.

Its not really a necessary feature when it takes less than 2 seconds to loads loads of things, such as news articles as you mentioned. And most things automatically update when you open the app anyways so

It will definitely save your battery if you turn it off. You wanted tips for saving battery, i gave you them. What more do you want from me?

The thing is Apple does battery life tests with all these features turned on. People become so obsessed with battery life that they turn their smartphones into dumb phones by disabling features.

I've seen web sites recommend disabling LTE, GPS, Bluetooth and other features to try and squeeze as much battery as they can out of their phones. We don't live on deserted islands. There are plenty of places to charge people's phones.

I've turned off background app refresh before and saw no difference in battery life. I'm just not a fan of people being advised to disable features on their phones in return for such little battery life gain.
 
Im having an issue for the last day, My usage is the same as stand-by time. meaning something is operating while the phone sleeps. I usually get 2 days out of my battery, today I will run out by 10pm. I cant figure out what it is

27% remaining with 12 hours of usage?! A LOT of people in here would love to reach that performance...
 
Yeah 12 hours of usage is good. But not when your phone is sleeping and it thinks it's still on. I am at 83% now with nearly 2 hours usage and 10 hours sleep. Much better.
