“A little change in usage habits can have weird and wonderful effects on your iPhone’s battery health,” Uzair Ghani writes for WCCFTech. “Here’s… what I did to make sure that my iPhone X’s battery stayed at 99% health before upgrading to the iPhone XS Max at the end of 2018.”
“Usually, this is believed to be the best and most common practice for charging an iPhone battery: You unplug it from the charger in the morning, and top it up before going to bed when the battery has completely died or is about to give up the ghost,” Ghani writes. “That’s the best way, only if you want to damage the battery to smithereens by the end of the year.”
“Follow the tips/guidelines below and you’ll preserve your iPhone’s battery health like a champ. And no, it’s not a hard thing to do at all. It’s just a change of habit,” Ghani writes. “If you are not using your iPhone and happen to be near a power source, whether it’s wired or wireless, put your phone on charge… Try and make sure that the battery does not drop below the 75% mark that often, even if it does, keep the 60% mark as a benchmark for ‘critical.'”

MacDailyNews Take: We just checked a Day One (November 3, 2017) iPhone X that is basically connected to a charger 20 hours per day. It was basically always on charge whenever possible. As you can see from the screenshot below, it currently has a Maximum Capacity of 99%:
You can check your iPhone’s current battery health by going to Settings > Battery > Battery Health.
I would take Uzair Ghani’s advice with a grain of salt. All vendors protect device battery health and lifetime by imposing charge/discharge limits and monitoring other conditions like temperature to control charge rates.
When your iPhone shuts down in a low battery situation, the actual battery capacity is probably still 40% or greater. This is standard practice for lithium-based batteries. Similarly, 100% does not mean that the battery is maxed out in terms of cell voltage. Apple, like all other mobile device vendors, defines an operational range for its batteries that avoids the dangers and damage associated with excessive charge or discharge.
I have an old iPad (still has the 32-pin dock connector), and it often gets used until it shuts down from a low battery. It still lasts a long time and I have never babied it.
I got mine on day 1 (iphone X). Its at 100% still. I simply keep it charged pretty much all the time. Wireless charger at work and home. Easy….
Li-ion batteries like to be topped up. Well, that’s my understanding over the years. I have been exercising this ever since the Li-ion batteries became widely used. I got most of my battery knowledge in my camera days (not saying all these info are true). There are complicated scientific explanations on this but I forgot. I seem to remember that a brand new Li-ion battery will last longer if it is charge cycled (between 100% and a few%) a few times when it’s new. I am not sure if this particular one was accurate or now obsolete.
Perhaps Google “Battery University” etc. if it still exists somewhere.
Also, I do not think Li-ion batteries shut itself down at 40% etc. From what I see, for example, the iPhone notifies a low battery situation at 20% but still keeps going until it goes really low, then shut itself down. I know (or understand) it is very harmful to the Li-ion batteries to completely deplete it.
His advice is worth the same as mine – Zero
Wow, Zero-fwit is back. Go away Zero F-Wit!
So tired of the articles with the 🐂💩 saying don’t leave it plugged in. It does ZERO harm. It’s softwaree. It tricked out even if plugged in. Then tops. Then trickles. It’s not always charging. How are these people tech writers?
Except when I leave the house and even not then, my iPhone 7 Plus never somes of the charger. It sits on my bedside table always fully charged and has never been below 98 percent charged. Still has a great battery three years at three years and counting.
