Apple MacBooks with Thunderbolt 3 ports running macOS Catalina 10.15.5 or newer have a battery health management feature that can prevent the MacBook from charging to 100%. If your MacBook has this feature, turn it off before beginning calibration.
Figure 2: Full-discharge and full-charge flags. Calibration occurs by applying a full charge, discharge and charge. This is done in the equipment or with a battery analyzer as part of battery maintenance.
Remember there are two different (but connected) systems at play, the battery management system, which monitors and controls the health of the battery, and the software user interface (and associated power control software), which reads data from the former to display an indication of battery charge status and level and respond to various flags (like shut down when the discharge flag is set).
So you're using your laptop and, all of the sudden, it dies. There was no battery warning from Windows---in fact, you recently checked and Windows said you had 30% battery power left. What's going on?
Even if you treat your laptop's battery properly, its capacity will decrease over time. Its built-in power meter estimates how much juice available and how much time on battery you have left---but it can sometimes give you incorrect estimates.
If you're taking proper care of your laptop's battery, you should be allowing it to discharge somewhat before plugging it back in and topping it off. You shouldn't be allowing your laptop's battery to die completely each time you use it, or even get extremely low. Performing regular top-ups will extend your battery's life.
However, this sort of behavior can confuse the laptop's battery meter. No matter how well you take care of the battery, its capacity will still decrease as a result of unavoidable factors like typical usage, age, and heat. If the battery isn't allowed to run from 100% down to 0% occasionally, the battery's power meter won't know how much juice is actually in the battery. That means your laptop may think it's at 30% capacity when it's really at 1%---and then it shuts down unexpectedly.
In reality, you likely don't have to do this that often if you're not too worried about your laptop's battery readings being completely precise. However, if you don't calibrate your battery regularly, you may eventually find your laptop suddenly dying on you when you're using it---without any prior warnings. When this happens, it's definitely time to calibrate the battery.
Some modern devices may not require battery calibration at all. For example, Apple recommends battery calibration for older Macs with user-replaceable batteries, but says it's not required for modern portable Macs with built-in batteries. Check your device manufacturer's documentation to learn whether battery calibration is necessary on your device or not.
Recalibrating your battery is simple: just let the battery run from 100% capacity straight down to almost dead, and then charging it back to full. The battery's power meter will see how long the battery actually lasts and get a much more accurate idea of how much capacity the battery has left.
Some laptop manufacturers include utilities that will calibrate the battery for you. These tools will usually just make sure your laptop has a full battery, disable power management settings, and allow the battery to run to empty so the battery's internal circuitry can get an idea of how long the battery lasts. Check your laptop manufacturer's website for information on using any utilities they provide.
You should also look at your laptop's manual or help files. Each manufacturer may recommend a slightly different calibration procedure or tool to ensure your laptop's battery is properly calibrated. Some manufacturers may even say this isn't necessary on their hardware (like Apple). However, there's no harm to performing a calibration, even if the manufacturer says it isn't necessary. It just takes some of your time. The calibration process essentially runs the battery through a full discharge and recharge cycle.
While it's a good idea to use any included utilities or just follow instructions specific to your laptop, you can also perform battery calibration without any specialized tools. The basic process is simple:
NOTE: If you want to calibrate the battery while you aren't using the computer, be sure your computer isn't set to automatically sleep, hibernate, or turn its display off while idle. If your computer automatically enters power-saving mode while you're away, it will save power and won't discharge properly. To find these options, head to Control Panel > Hardware and Sound > Power Options > Change plan settings.
The key to calibration is allowing the battery to run from 100% to almost empty, then charging it all the way up to 100% again, which may not happen in normal use. Once you've gone through this full charge cycle, the battery will know how much juice it has and report more accurate readings.
iOS 14.5 includes an update where the battery health reporting system will recalibrate maximum battery capacity* and peak performance capability on iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max to address inaccurate estimates of battery health reporting for some users. Symptoms of this bug include unexpected battery drain behavior or, in a small number of instances, reduced peak performance capability. This inaccurate battery health reporting does not reflect an issue with actual battery health.
While the battery health reporting system is recalibrating, you will see a message in Settings > Battery > Battery Health. Recalibration of maximum capacity and peak performance capability happens during regular charge cycles, and this process might take a few weeks. The displayed maximum capacity percentage will not change during recalibration. Peak performance capability might be updated, but this might not be noticeable by most users. If a previous degraded battery message was displayed, this message will be removed after updating to iOS 14.5.
In a small number of instances, recalibration might not be successful and a new battery service message will appear. If this occurs, an Apple Authorized Service Provider can replace the battery free of charge to restore full performance and capacity. This does not indicate a safety issue and your battery can still be used.
* Maximum battery capacity is determined using a set of algorithms and measurements taken during use. Over time, these algorithms might be updated to provide the best estimate of maximum battery capacity.
Recalibration for maximum capacity and peak performance capability will happen over time with regular charge cycles. If the process is successful, the recalibration message will be removed and your maximum capacity percentage will be updated.
If a previous degraded battery message was displayed, this message will be removed after updating to iOS 14.5. Recalibration for maximum capacity and peak performance capability will happen over time with regular charge cycles. If the process is successful, the recalibration message will be removed and your maximum capacity percentage will be updated.
This message does not indicate a safety issue. Your battery can still be used. However, you might be experiencing more noticeable battery and performance issues. An Apple Authorized Service Provider can replace the battery free of charge to restore full performance and capacity. Learn more about getting service for your battery.
Because current battery health reporting might be inaccurate, we advise waiting until the recalibration process completes to contact an Apple Authorized Service Provider. If your device is covered by warranty, AppleCare+, or consumer law, service coverage for a battery with this issue will be temporarily extended to cover your recalibration period. If your iPhone 11, iPhone 11 Pro, or iPhone 11 Pro Max recommends battery service after recalibration, contact Apple Support to learn more about service options. If your iPhone 11, iPhone 11 Pro, or iPhone 11 Pro Max has any damage which impairs the ability to complete the repair, such as a cracked screen, that issue will need to be resolved prior to the service. In some cases, there may be a cost associated with the additional repair.
You can also contact Apple Support if you previously paid to service an out-of-warranty battery for your iPhone 11, iPhone 11 Pro, or iPhone 11 Pro Max after seeing a battery health degraded message or experiencing unexpected battery behavior.
Im sorry to hear you are having this issues. Considering that the iPhone 11 came out about 3 years ago, this may be due to the lithium ion battery degrading in your device. To check this, go to settings, battery, battery health and charging. Please screenshot results or comment the number.
Alright so with the battery health being 100% there is not much that you can do. I would open the Apple support app>tap on the device in concern>tap Device Performance>Tap Battery performance. The iPhone will run a hardware test automatically and bring up any possible issues. If nothing comes up, continue through after the test and contact apple support. They will be able to run a remote hardware test which should bring up charging habits and see what is causing the battery drain, and whether or not It is normal for your device to have that issues.
What's the best way to calibrate the battery meter? I thought it might be to fully discharge as I have been doing which does seem to sort of work, but I don't like that the battery life had dropped from 12 hours to 9:15. Should I be leaving it on the charger for a while after it shows 100%?
Let the device drain the battery until it switches off (dies) as you did. The real battery level is zero at that point. Now the software of the device has to learn the new zero level. This can be achieved by doing a full hard reset of the device immediately after it is connected to the charger. Do not skip this step. Regardless of when the battery indicator reaches 100% again, leave the device on the charger for at least 6 hours. This is to learn the device the real 100% charge level.
Device is ready to use now, but you will have to re-enter your settings because of the full reset. If in doubt if you have reached the ultimum with the battery indicator, you can repeat the whole re-cal procedure.
