How fast should the battery run down? I've noticed shorter life recently, so I took a couple of snaps of the usage. Battery health reads at 85% but I did not buy this new and it's possible that it's already had a battery change. Seems to kinda run down quickly at the end, but that might be an illusion, based on what it shows.

Quick look turns up iOS 13 has shortened battery life? Maybe that's it?

Not sure how reading apple news can kill a battery so quickly. Reading the news for 16 minutes takes 38% of the battery? Heck running the GPS for an hour took less! I took it off charger at 7am, read the news for 16m apparently, took a bike ride and at 3:40 the low power indicator came on at 20%. I made sure to clear MMR after the ride as I've noticed it will run in the background for a long time. Edit: nevermind, it's not using 38% of the battery, reading the news for 21 minutes used 38% of the battery usage. Still. Rapid drain if you ask me.

Also, what is the difference between on and off screen time? Time spent running apps in the background?

I'm thinking I've got nothing to lose from ordering at $25 battery.

It seems to drop linearly, although the sudden drop at the end I was entering in calories--screen on, but it dropped kinda quickly if you ask me.

It is probably battery natural aging. I replaced my iPhone6's battery as well. There's a 20 or so % chance it doesn't work but usually if you buy the better battery from Amazon they tends to be good for another few years.

That's what I'm thinking, and after replacing the 6's battery I'm thinking an 6S is going to be a snap. But if it's normal for it to go flat after what, 8 hours of light usage, then it's not justified.

Touch the screen where it says “battery health”. If the percentage is below about 85 percent it’s going to be weak. When I had a 6s plus mine was replaced at 88 percent and I could tell a huge difference.

Apple says that once the battery health % reaches mid-80s and lower, that usage time will decline noticeably. Apple replaces batteries in these for $50 now so I wouldn't bother with 3rd-party repair shops or DIY (because the battery you get, no matter where it's from, will be garbage compared to an Apple battery).

Forgot to say, battery health says 85%.

Sounds like it's time for a new battery. Not sure when the stores will be open again? I don't think I can send this out for repair, not with MFA turned on and using this phone. I think...

It's 10 minutes and $25 to change at home. Too bad I can't buy a genuine battery, I'd spring the extra coin for that.

That app that runs the GPS all the time is what's killing you. GPS takes a lot of power.

Was only on for an hour. Then I made sure to kill it. But I don't get how reading the news for 16 minutes is more of a battery hog than using GPS for an hour. Screen time is quite the hog, apparently.

Take to the Apple store, Verizon, AT&T, etc to get your battery replaced. Did this with my wife's iPhone 6S. Do a search on "Apple iPhone 6s battery lawsuit"

What is the health percentage of the battery as reported by iOS?

Condemnation critieria for Li-ion is usually 20% reduction in nameplate capacity, or an increase in impedance associated with discharge rates and conduction voltages. Since an iphone isnt a high drain device, the former is the more important one... Youre getting there...

Check here. They say they are starting to reopen their stores. None around me say they're open yet or give any opening date that they're planning. Best Buy is an official Apple repair provider so they can replace the battery, using an official Apple battery, too. They say they've got stores open and are opening more all the time. For a repair, I'm sure they can/will do this as a curbside drop-off and pick-up when done.

I suspect won't impact the repair process but you would be in a bind if you need to securely login/authenticate and this is your only device that is set up to allow it.

For "the extra coin", let Apple do it and you'll get a genuine battery.

This is my only MFA device. Not sure if work would let me set something else up also... I should ask on that.

Just put in an aftermarket battery into the wife's iPhone (after hers swelled and quit), so it'd be kinda snobbish of me to do otherwise. Very easy job to do.

Just checked and it is an Apple battery in my phone--bit rough getting in there, so maybe it was a late model and never been opened. Wife's had an aftermarket one in it already (perhaps there's a tie between aftermarket and failure, eh?). I'm a bit surprised, as I bought it used only a few months ago.

I might just wait a few weeks and see what happens. Maybe the Apple store will open up again, and I can schedule a replacement.

Edit: IT says MFA only works on one device, so if this goes down I've got problems.

I replaced my iPhone 7's battery at 85% and noticed a huge difference after doing so. Cost $60 or so at a phone repair shop. Worked great ever since, and that was about 6 months ago.
