How to use iPhone battery health management settings, introduced with iOS 11.3

Since iOS 11.3, the system
operating at the apple is equipped with new features describedIn
This item, Besides. Among them, there are new options for
autonomy and battery management, implemented in response to the case
which caused a scandal at the start of the year, namely, the automatic restriction of
iPhone processors with too worn out batteries.
See herewhich iPhones are affected. Still, even if
the initiative was to want to reduce sudden extinctions due to
too intensive use of the processor and a battery that is too old, there is
had arise of shield among users.

As a result, Apple has on the one hand launched a replacement program for
discounted battery,
see the details here on this subject. On the other hand,iOS 11.3
now allowsdisable this processor throttling. Here is
how to do it precisely:

Check battery for wear

What causes the processor to stall is aunique
symptom: too much wear on the iPhone battery.
Wear and tear is normal with time and use, as it is inherent to the principle
operation of a smartphone battery.

This is therefore the first thing to check if you have the impression that your
iPhone runs slowly, including apps that launch slowly,
lag time when using the keyboard and other discomforts experienced
in general iOS usage.

To check the health of your battery, see in “Settings >
Battery > Battery Status".maximum capacity
indicates battery health. 100% everything is fine, it's like new.
Apple considers that from 80%, it is necessary to consider changing the
battery.

Still, around 70-80% and obviously below, the
battery is no longer in good shape and may no longer support intense peaks
CPU usage, which can cause iPhone to shut down unexpectedly. If
you are in these figures, so be aware that a shutdown of the iPhone can occur
produce at any time.

After a first unexpected shutdown of this kind, Apple activates a special mode
“performance management”. This slows down the processor, and it's
precisely this mode which was until then activated automatically in
owners of iPhones with worn out batteries, without their knowledge. See
here to learn more about
the behavior of an iPhone running with a slow processor.

But since iOS 11.3 it can be deactivated by hand, which allows you to
regain normal performance, but also to have more
chance of seeing your iPhone shut down without warning. See in any case below
commentdisable processor throttling.

Disable phone blocking

Go to “Settings > Battery > Battery Status”, and see the
second title, “Optimum performance capacity”.

Five different messages can then be displayed at this level:

1.Your battery can currently support a capacity of
performance optimale normale: everything is fine, there is no problem
to report with the iPhone battery

2.This iPhone turned off unexpectedly because the battery did not
was able to provide the optimal energy needed. Performance management mode has
been enabled to prevent this from happening again. Disable…: the
battery capacity is insufficient to provide enough power to the
system, there is therefore automatic activation of the “performance management” mode
which restricts the processor.

There is a "Disable" option at the end of the message:press
on it to jailbreak the processor. Please note, the management method of
performance automatically reactivates after the next unexpected shutdown,
with always the possibility of manually deactivating it afterwards. HAS
also note that deactivating this mode has the consequences of making
the iPhone less stable, with possible unexpected shutdowns to come.

3.This iPhone is not able to determine the health status of the
battery. An Apple Authorized Service Provider can repair or replace the
battery. Learn more about repair options…: the state of
the battery could not be determined for various reasons, such as
incorrect installation of the battery or an unknown part contained
in the battery, Apple recommends changing it.

4.This iPhone turned off unexpectedly because the battery did not
was able to provide the optimal energy needed. You have manually deactivated the
performance management protections.: indicates that
the user has disabled "performance management" mode.

5.The health of your battery has significantly deteriorated. A
Apple Authorized Service Provider can replace the battery so that it
regains optimal capacity and performance. Learn more about
repair options…: indicates that the battery is too degraded and
Apple recommends that the user replace it to find
normal use conditions.

Q&A

Which iPhones are affected?

All theiPhone 6 and newer, including iPhone SE are
concerned, except iPhone 8 andnew
more efficient battery management components, which translates
by a much less noticeable processor slowdown for the user.
Obviously, the battery wears out in the same way as with the old ones.
iPhone, in the long term therefore, the batteries of iPhone 8 and
replaced.

Which iPads are affected?

Apple tablets would not be affected by this concern about peaks in
performance and unexpected shutdown, given their very design and design
wide of the battery.

What does “maximum battery capacity” mean?

It allows you to gauge the state of wear of a battery. 100% everything is fine. HAS
95%, the iPhone may already experience unexpected shutdowns depending on the case. In
below 80%, Apple recommends changing the battery, because
this has experienced more than approximately 500 recharging cycles, hence a large
wear and even greater risks of unexpected shutdowns.

Can we completely disable "performance management" mode?
?

Not really: it is possible to deactivate it by hand, but it
will automatically activate again the next time the iPhone shuts down unexpectedly
due to high battery usage by the processor.

Is it dangerous to disable "performance management" mode
?

No, this has no risk for the battery or the phone, since
the device automatically turns off if the energy demand is too intensive
and the battery cannot support it. On the other hand, it could be more serious
if the remaining charge percentage shows 20% and iPhone turns off
then in the middle of an important call, when you thought you still had enough
of energy.

Do not hesitate to tell us about your experience with this unclamping of the
processor on your iPhone.
