Mac says "Charging On Hold (Rarely Used On Battery)". What does that mean?
Updated 6 November 2026 · Who measures this.
macOS is holding the charge on purpose, to protect the battery. Your Mac is plugged in and working normally, and nothing is broken. The hold ends by itself, and you can override it from the battery menu. Several holds carry similar labels, and one case that looks like a hold is really an adapter that can't keep up.
What does each status mean?
All 3 messages below are macOS managing the charge. The first 2 are Optimized Battery Charging, and the third is a limit you set yourself.
| Battery menu says | What is happening | What to do |
|---|---|---|
| "Charging On Hold" | Optimized Battery Charging (macOS Big Sur and later) has learned your routine. It delays charging past 80% when it predicts the Mac will stay on power for a while, and aims to reach 100% by the time you usually unplug | Nothing, unless you need 100% now |
| "Charging On Hold (Rarely Used On Battery)" | The same feature on a Mac that lives on the adapter. You almost never run on battery, so macOS holds the charge at 80% for as long as it sees no need for a full charge | Nothing, unless you need 100% now |
| "Charged to [%] Limit" or "Charging to [%] Limit" | Charge Limit, your own setting (macOS 26.4 or later, Apple silicon), anywhere between 80% and 100%. The Mac charges to within a few points of the limit and stops. If the level drops more than 5% while plugged in, charging resumes | Raise the limit in System Settings if you want more |
One more case has no status at all. Apple notes that if Optimized Battery Charging is off and the Mac still won't charge past 80%, the battery may be too warm. Move it somewhere cooler and better ventilated.
The charge controller keeps its own record, and the Terminal command on Mac not charging past 80% reads it. It names a charge limit outright. Optimized Battery Charging shows as a code we have not decoded, because we have not recorded a Mac in that state.
Need 100% right now?
Click the battery icon in the menu bar and choose Charge to Full Now. That overrides both the optimized hold and a charge limit for the current charge.
For a permanent change, go to System Settings → Battery and click the info button next to Charging (labelled Battery Health on older versions of macOS). There you can turn Optimized Battery Charging off, or off until tomorrow, and on macOS 26.4 or later set the Charge Limit.
Should you fight the hold at all?
Mostly no. Hours at 100% and heat are among the things that age a lithium battery, and both features exist to reduce the first one. Apple also names temperature history and charging pattern.
The one good reason to override is a wrong guess about your schedule, with shift work or irregular travel: the machine-learned routine assumes you have a routine.
When "on hold" is not the real story
Everything above assumes the adapter has watts to spare. If the Mac needs more power than the adapter delivers, the battery covers the difference and the charge drops while you are plugged in. That happens with a 30 W adapter on a Mac that needs 45 W, a cable that can't carry what the adapter can make, or a hub that keeps 15 W for itself. macOS may say "Not Charging" or, from macOS 26.4, "Slow Charger", but no status says how many watts are missing.
WattMate's charging screen shows that. It shows the watts arriving from the adapter, splits them between the Mac and the battery, and says so in numbers when the Mac needs more than the adapter delivers: where the adapter's watts go.
Questions people ask
Is "Charging On Hold" bad for the battery?
It is the opposite: the hold exists to slow battery aging. It releases itself when macOS predicts you'll need a full charge.
Why does my Mac sometimes charge to 100% even with a limit set?
To keep its charge estimate accurate. In Apple's words, the Mac "will occasionally charge to 100% to maintain accurate battery state-of-charge estimates". That is documented for both Optimized Battery Charging and Charge Limit.
The percentage is dropping while plugged in. Is that the hold?
With a Charge Limit, charging resumes after a drop of more than 5%. Under Optimized Battery Charging Apple documents no threshold: the hold releases when macOS predicts you'll need a full charge. If there is no hold message and the charge keeps falling under load, it is the adapter case above, and it is about watts, not settings.
How it was checked
| Statuses and settings | Apple's support articles 102338 and 102397 and the Mac User Guide, read on 2 November 2026. |
| "Rarely Used On Battery" | Apple documented this exact wording in an earlier version of 102338, published 12 January 2024. The current text no longer lists it. |
| The adapter examples | Illustrations of the case, not measurements. |
What this doesn't show
- Which hold your own Mac is in, from the controller's record. We have not recorded the code for Optimized Battery Charging.
- When a hold will end. Apple documents no time for it.
