Hi everyone Aaron here for ZolloTech
And as you can see, I have three different phones here and all three of them have different maximum battery capacities
Now this was a newer feature that was introduced later in iOS 11 that told us more about the battery and the battery
Health and many of you have asked me about that as your number starts to go down from 100%
Many of you have been concerned if you should pay attention to it or what you should do
So hopefully I can clarify some of that
So the first thing you need to know is all three of these phones have different capacities and this one is my iPhone I use
regularly and
If I go into settings we go down to battery
There's battery health and keep in mind. This is a beta so this 100% that I have on here
While I'm pretty sure it's accurate. It may not be because beta means the software is not done
So we're not as a hundred percent sure that it's correct
The main thing we should pay attention to here is not so much the maximum capacity, but it's the peak performance capability
which means the battery can supply enough voltage to power the
Processor and the RAM or the cameras and all of those things without shutting off the phone
So the processor can perform as fast as it possibly can so in this case
It says your battery is currently supporting normal peak performance, which we would expect with a brand new or 100% battery capacity
So this is a phone from the release day of the iPhone 10 and it's still doing well. Now here's the other one
This is an iPhone 10. This is my wife's iPhone 10. It's been used every single day since it was released
and we'll go to settings and you'll see this one is at
99% so this one's doing really well again peak performance capability and
Nothing is done specific to to keep these battery capacities up. In fact, I don't pay attention to it
Neither does my wife we don't care
we just plug it in when we're using it or if we need to use it or if it's low we plug it in if
We need to charge it
We charge it if we don't we don't and before we go to bed, it goes on a wireless charger
So we wake up with it at 100%
once you hit 100% Apple regulates that voltage cuts the power so you can never overcharge your battery and
It also doesn't stay hot or anything like that
So it's nice and cool, which heat is a big problem for batteries if it's really really hot
And I've covered that in a different video
however
This iPhone this is an iPhone 7 plus that I used for a full year and if we go in you'll see we're at 93%
Capacity so these are normal depletion rates because Apple says after two years you should be at 80% or more
So we're at 93% It was used for a year. So that's about right now
the only time we really need to concern ourselves with this is
If your phone shuts off
Now if it does it's going to give you a message when it reboots in that health center
That looks something like this. You'll see here. It says the maximum capacity is 82% and it says
This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power
You have manually disabled performance management protections
Your battery's health is significantly degraded an Apple authorized service provider can replace the battery to restore full performance and capacity
now what that means is if
You remember when Apple kind of got caught or at least people figured out that they were slowing the processor down?
That's what they have to do. So your phone doesn't shut off and that's what this is about
So once it can't deliver the full voltage because the battery has degraded the phone may be under full load
maybe you're watching a video and
maybe you switch you play a game you open the camera and now it's pulling enough voltage or using the
Processor enough that it doesn't have the voltage available. The phone will shut off
It's as though your lights in your house don't have enough power. So they either dim or just turn off altogether
So that's kind of the same thing that's going on here
Now many people have said my battery's down to 93% I need to have my battery replaced
well
You really don't unless you're having terrible battery life or your peak performance
Capability is not available and then you can have it replaced and now because of what has happened in the past
It's $30 to replace your battery at Apple.
Now If you don't have Apple do it you can buy one at Amazon or ifixit
They have batteries available and you can swap them yourself or there might be authorized service centers
So if you have those centers available, or you need to replace it
those are the circumstances I would worry about it under and
Then I would just use your phone if you only use your phone for a year and then you swap it or two years
I honestly wouldn't even pay attention to it
I would ignore it if you're going to use a long term, then you might want to pay more attention to it
But let me know your experience in the comments below. What's your maximum capacity at and have you had your battery replaced in?
How's your phone going on now? And what phone are you using?
