    I am thinking about getting a Smart battery case for my iPhone. Wondering if it hurts the iPhones battery by keeping it on all the time. Does anyone use a Smart battery case 24/7 and if so what is your phones battery health in settings?

    I had an iPhone 7 with the Apple Smart Battery Case.

    I owned both for around 11 months or so from brand new. I used to use the case exclusively for charging. And half the time it was on.

    After 7-8 months of usage, before 11.3 Beta was released, it was at 97%. During 11.3 Beta 1 to 11.3 GM it went down to 92% in less than 2 months or so.

    Thanks for your reply. I have an iPhone 6s that I have had for two years and hope to get a battery replacement later this year but I am willing to buy a Smart battery case to use till then and after I get a battery replacement only use it off and on until my battery starts to go bad again and then use it full time. Call me crazy for thinking this way but I think it would be really handy for me to have when I would need the extra power.

    The 7 I had lived its whole life in a smart battery case - the phone rarely went below 100% so I'm not sure how its battery was affected. Still sold it for a good price.

    I have a 7 I purchased when they first came out. I have kept it in a battery case for most of it's life. I'm getting ready to move on to an 8+ I got a good deal on, so I'll be selling the battery case cheap as it's used.

    I love the case. It powers the phone all day. My internal battery has almost never been used, It's at 97%.

    Did you guys all like the Smart Battery Case? How’s the grip on it? Does it protect your phone enough?

    If it falls, whether or not the phone breaks but the case will definitely stop working.

    I dont see any short-term consequences of using the battery case, but I do see the potential for long-term. Batteries must be used in order to maintain their health. If you leave a MacBook plugged in 24/7 and treat it as a desktop, its battery will degrade much faster than it should (based on cycle count).

    A friend of mine doe this with his MBA regardless of my suggestion to just let it drain once in a while. He has 30 cycles on the battery after 4 years - battery is at 91% health. In comparison, after 4.5 years with my MBA, 1267 cycles, it was at 88% when I sold it. The battery is only rated for 80% health after 1000 cycles. So I went way above and beyond by actual using my battery. No way he will see 1000 cycles before hitting 80%.

    Except he’s used his MacBook for 4 YEARS and still has 90% life

    You are entirely missing the point. His battery will never see the intended life for it. We are strictly talking the battery here. I have a 9 year old MBP that still runs great. It’s irrelevant how old the machine is.

    no but my point is the guy managed to extend the useful life of the battery of his laptop (which, arguably, is what matters).
    He got to USE his laptop for 4 years and today if he wants to use the battery, it still has 90% of the original battery capacity. Compared to the other way, he'd only get 88%.... Sure the battery will never see 1000 cycles or whatever it's actually rated for...but who cares in terms of the laptops's usefulness to its owner, the former macbook will serve its owner with a better experience, 4 years in.

    No, you are only comparing only two scenarios. One who uses a cycle almost every single day, and one who uses 8 a year. If He would have used 30-40 cycles a year, the battery could have easily lasted him 5+ years and still be well over 90%. Just because he got 4 years out of usage doesn't mean he couldn't have gotten substantially more. Once you start using a battery that has been hardly used after 4 years, it degrades at a faster rate. Battery wear is not linear and more so if its not taken care of.
