We have an iPhone 6s that was replaced by Apple right before it was replaced with a newer model phone. The battery health indicator says it is at 95 percent. My son is using the phone for summer day camp as he doesn’t want to take his nicer phone. He says the battery life is terrible. I’m wondering if he is just used to higher capacity batteries...like 7 plus and X batteries. I’m happy to replace the battery but Apple said it won’t make a difference.

He’s probably got bad signal and he’s on Snapchat all day. Completely normal. It’s down to his usage 99%.

It’s probably both bad signal and that he’s used to higher capacity battery.

6s battery does suck on iOS 11 and iOS 12. And it's just okay on iOS 10. It is good on iOS 9 though.

Even with a fresh battery.

No social media for my kid. He is allowed to text friends...but only using messages app.

His signal is good....it’s on Verizon and he’s been in areas with good reception. I’m thinking he just is used to the better battery life of bigger/newer phones.

yeah check signal strength and obv see what he does....Games and snapchat can drain batteries quick.

Also, check for things like if background app refresh is on (turn it off), and go into privacy-location services and see what is on always that can be changed to when app is in use. On top of that turn off some of the system services too that aren't important (like ads).

No social media, but he’s away at camp?

Gotta be in it to win it
I find battery life on iOS 11.4.1 to be excellent. And also find there is a difference in battery life between lte and WiFi with WiFi winning.

Why your sons 6s is getting “bad” battery life is hard to say, but maybe it’s all the screen on time at maximum brightness.

Day camp. And he doesn’t have control off his Apple ID. Believe me..he barely even wants to text. He isn’t in to social media.
Like me!

Erm... other than Instagram and Twitter.

That could be it. He does like maximum brightness. He does put it in low power mode during the day.

He is on 11.4.

Updating to iOS 11.4.1 might be worth a try.

What's the usage like? Because if he's getting 5 hours with max brightness and LTE, then it will not last more than that, even more so considering it's on iOS 11.
I am getting 6.5 hours with my 6s on LTE with high brightness, but I am on iOS 9.

6s with a battery replaced less than 2 months ago under the replacement plan.

Upgraded to 11.4 and suddenly my battery was rapidly draining with very light use.

Upgraded to 11.4.1 but I still don't get more than half a day, even with very light use.

Hopefully 12 will fix this problem. Otherwise I'll need a new phone -- Apple or otherwise.

You might wanna restore as new and see if that makes any difference.

All of my iPhones on 11.4 had battery issues, so that might have been an issue. Never existed on 11.3.1

And the all were solved with 11.4.1 or iOS 12 beta, depending on the device

11.4 definitely contributed to some weird battery strain
