Hi Stephen, Graham’s post which I replied to was regarding his MacBook Air’s battery not an iPhones battery!
You can believe the Apple Store if you wish, that’s your choice, but I’ll stick with my original post on how to charge lithium-ion batteries on my iPhone. “According to Battery University, the lithium-ion battery in your smartphone will last longest if you keep it 65% to 75% charged at all times. Clearly, it’s impractical to always keep your phone charge between those levels – but at least you know what’s ideal. If you can’t do that, shoot for keeping its charge level between 45% and 75%. Charging to 100%, or overnight? Fully discharging before plugging in? These common practices can shorten the usable life of your battery, according to Cadex, a company that offers devices that test smartphone batteries, among others. Cadex offers a lot of information on its Battery University website, including about lithium-ion batteries – the type that powers smartphones.” Kind regards, Ronni Ronni Brown’s iPad Pro 12.9-inch 256GB > On 24 Jan 2019, at 2:43 pm, Stephen Chape <[email protected]> wrote: > > Hi folks. > Took my grand daughter to the Apple Store in Perth a couple of weeks ago to > get new battery in her iPhone 6. > They tested it and said it did not need a new battery. > > But they did say that she was charging it too frequently. > We were told to let it get as low as possible then charge up to 100%. > They said the more often it is charged, the faster the battery will wear out. > So do not keep giving it “top ups”. > >> On 22 Jan 2019, at 5:39 pm, Graham Rabe <[email protected]> wrote: >> >> Hello WAMUGers, >> >> What is best practice when it comes to charging Apple laptops?
