<\/p>\nRUSH: Okay, now to your phone — your pocket computer — and battery. You people have had battery-life questions for as long as they\u2019ve had devices, and they have had battery-operational questions for as long as they\u2019ve had devices. How many of you…? Let\u2019s just talk about your phone for the moment. How many of you plug in your phone at night and have it charging the whole time you\u2019re asleep so that when you wake up and start the day, it\u2019s at 100%? And how many of you in that situation have asked yourself if you\u2019re damaging the battery by leaving it plugged in so many hours after it\u2019s charged?<\/p>\n
<\/p>\n
And so how many of you have sought answers to that question? And you can find them. They\u2019re all over the internet, and the general consensus now is that power-management systems in these devices are so sophisticated that you don\u2019t have to worry about it. “Leave that phone plugged in! Leave it plugged in overnight. You won\u2019t hurt it.” That is the standard-operating theory, and this is what most people who are interested in this have discovered. So they continue to do it. Other people don\u2019t believe it and don\u2019t leave their phones plugged in all night.<\/p>\n
People deal with their devices in very personal ways. I have my own philosophies about this. I never leave the phone charging overnight. Never. But that\u2019s because I\u2019m constantly surrounded by chargers. I can show up here with my… I never let the phone get below 70%, though. If it gets below 70% and I can, I charge it, and I\u2019m never in a situation where I can\u2019t charge my phone. Even on the golf course, I can charge my phone. It\u2019s something I care about; I make provisions for it. So, anyway, iOS 13 beta 1 was released on Monday.<\/p>\n

<\/p>\n
And the tech media got hold of it and started playing around with it and they found something in it that doesn\u2019t make any sense, and they\u2019re all excited about it. It\u2019s in the settings for the battery, and if you click on “battery health” — which I\u2019m doing now — there\u2019s a new switch. It\u2019s called “optimized battery charging.” You can turn it on or leave it off. Here\u2019s what it says: “To reduce battery aging, iPhone learns from your daily charging routine so it can wait to finish charging past 80% until you need to use it.”<\/p>\n
Now, most people are going to say, “Whoa, what?” Let me explain this to you, because what I think Apple\u2019s admitting here is it\u2019s not good to leave your phone plugged in and charging overnight while you\u2019re asleep. Otherwise, they wouldn\u2019t have created the feature. The way the charging works, when you plug your phone in to charge, it will charge at its fastest rate up to 80%. At 80%, it stops charging fast and it starts trickle charging so as not to damage the battery. That\u2019s why charging seems to take so damn long once you get past 90%, 95%.<\/p>\n
What Apple has put in their new iOS 13, is the phone will learn that if you go to bed, whatever time you go to bed. If you get up the same time, and your phone is charging overnight, what\u2019s gonna happen is that when your phone reaches 80% (say at 2 in the morning) it\u2019ll stop charging until two hours before you wake up. And then if you get up at 7, at 5 a.m., it will start charging again so that when you wake up, it will have recently reached 100%. In that way, it\u2019s not been on the charger all night. That\u2019s what this battery feature is.<\/p>\n
So, I got an email, “Is this really true? Can they really do this?” I said, “Is what true?” Because now what Apple\u2019s admitted here is it may not be good to leave your phone plugged in and charging all night while you\u2019re asleep, if they\u2019ve got this new feature. It actually is very cool. You have total control over it, at least whether it\u2019s on or off. You can\u2019t hasten the… I don\u2019t know how long it\u2019s going to take the phone to learn this. Probably a week. But if you get up at the same time every day — let\u2019s just say 7 o\u2019clock — and let\u2019s say you go to bed roughly the same time.<\/p>\n
For this example, we\u2019ll say you go to bed at midnight and get up at 7. You plug your phone in at midnight, and it starts charging. When it hits 80%, it\u2019s gonna stop, if this feature\u2019s on. And then two hours before the phone thinks you\u2019re gonna wake up — which is 7 a.m., at 5 a.m. — it will resume charging at the trickle charge rate and it\u2019ll take hour and a half max, probably, to charge from 80% to a 100%. The point is that it reaches 1% right about the time you wake up rather than 3 in the morning or 2 in the morning and stay on the charger fully charged which they\u2019re now saying is not good.<\/p>\n
After all this time, this is a tantamount admission that maybe… Now, this is not gonna expand battery life per day. It\u2019s not gonna mean your battery will last longer during the day. What it will mean is your battery will last many more months at full capacity. That\u2019s what they\u2019re saying. Instead of a battery lasting a year and a half or two years, you may get 2-1\/2 years at 95 to 100% capacity out of it rather than it losing capacity at a normal rate. So this feature is not designed to give you more power during the day, longer battery life.<\/p>\n

<\/p>\n
It\u2019s designed to prolong the overall lifetime of your battery. It\u2019s a pretty cool feature, actually. But you don\u2019t have to use it if you don\u2019t want to. It\u2019s totally optional, turn it on or off. And who knows, it may not even survive the beta process. When they release this in September, it may not even be in there. I mean, that\u2019s what the testing is about here to see if this actually works. But that\u2019s the plan — and if it does survive and if it does work, then it probably will… I know, “But, Rush, what if I get up at different times?”<\/p>\n
Yeah, that\u2019s gonna be a problem. It\u2019s gonna learn what it thinks is your closest-to wake-up time and base its overnight behavior on that. So if you have to get up two hours earlier than you normally do one day, you might not wake up to a fully charged phone. In that case you\u2019ll turn the feature off before you go to bed and just leave it charged. You can do it one or two nights a week. It won\u2019t hurt it. I don\u2019t know if it hurts it anyway. But, anyway, I\u2019ve had three questions about this in the email, which is why I decided to answer it.<\/p>\n","protected":false},"excerpt":{"rendered":"
