If that did not fix it

Drain continues after the first week

A new Air that still loses a third of its charge in a normal morning after indexing and iCloud have finished is usually running something you did not install on purpose. Migration Assistant carries over old login items and Intel-era helper apps that run under Rosetta, and each of those keeps the performance cores busy.

Open System Settings, General, Login Items and clear the list, then check Activity Monitor for anything marked Intel. If the Energy tab is clean and the machine still drains, we read the battery's cycle count and cell voltages on the bench and tell you whether to return it to the seller before the window closes.

New machine, fast drain

Sudden drain on a new Air is usually software, not the battery.

A MacBook Air M4 is rated for most of a working day on mixed use. When a new one empties in a few hours the cause is almost always something running in the background rather than a faulty cell, and the Energy tab in Activity Monitor will name it.

First-run sync is the most common culprit. Photos, Drive and Messages all index in the background after setup, and Spotlight rebuilds its index at the same time. Leaving the machine plugged in until that settles resolves a large share of cases.

  • Activity Monitor's Energy tab names the process drawing the power.

Checking which app drains a new MacBook Air M4 battery in the energy view

The full answer

Air M4 should give 18+ hours - if it dies in 4, here's what's eating the battery.

A brand-new MacBook Air M4 should last 15-18 hours of mixed use. Fast drain on a new machine is usually background activity, not a hardware fault. Open Activity Monitor → Energy tab to see which apps are using power. Common culprits: 1) Initial iCloud sync (Photos, Drive, Messages) - leave it plugged in overnight to finish syncing. 2) Spotlight indexing after migration - takes 4-12 hours on first boot. 3) Time Machine first backup. 4) A second-display via USB-C cuts battery by 30-40%. 5) Browser tabs auto-playing video.

Quick fixes: turn on Low Power Mode for the first day (Battery settings), disable Background App Refresh for non-essential apps, set Display brightness to 50%, and keep keyboard backlight off. After the first 24-48 hours, drain should normalise. Still dying fast? It could be a defective cell - book a free battery health check at our Dubai workshop within Apple's 14-day return window.

Unlicensed software running in the background can also drain a battery; see what cracked Photoshop does to a MacBook Air.

When a background process keeps the chip busy and the steps above do not stop it, a clean macOS setup under MacBook software repair can bring battery life back without new parts.

Drain overnight often comes with heat; see a MacBook Air M2 that overheats in sleep mode for the same fault on the previous model.

From the bench: what we see with this one

The number that matters on a new M4 Air is the drop in percent over a timed hour of your real work, rather than the hours-remaining estimate. We ask people to note the percentage at the start and end of a sixty-minute stretch with the screen at half brightness. Below ten percent an hour is healthy. Twenty or more with light use means a process is awake, and in nearly every case on the Media City bench it has been a cloud sync client, often two of them fighting over the same folder.

Keep an eye on Dubai heat as well. An Air left in a car for an afternoon reports lower capacity for a day or two afterwards while the battery controller recalibrates. That is not a fault. A machine that reads below ninety percent maximum capacity within its first months is, and that one goes back to Apple.

Finding us

Office 45, Concord Tower

Azizi Technologies operates two Dubai locations: the main workshop at Office 45, 10th floor of Concord Tower in Dubai Media City, and a second office at the IT Center Building in Bur Dubai. Concord Tower is a short walk from Dubai Internet City metro, with visitor parking on site (first 15 minutes free, then paid).

No appointment is needed during workshop hours, Mon-Sat 9AM-7PM, Fri break 12-2PM · Sun closed. Walk in with the device for a free diagnosis. Repairs are walk-in only; send photos on WhatsApp first if you want the likely cost before the trip.

Walk in, no appointment

Free diagnosis at either Dubai workshop during workshop hours. We no longer collect repairs; businesses on an AMC can hand devices to the engineer on a scheduled visit.

How a repair runs

Diagnosis first, then a written quote before any work starts, then the repair, tested and returned with the work covered by our warranty.

FAQ

Frequently asked questions

4 direct answers from the Azizi Technologies team.

Is Low Power Mode safe to leave on permanently?
It is. Low Power Mode lowers the chip's clock ceiling and screen brightness slightly and most people cannot tell the difference in Office or Safari. Turn it off for video exports or compiling. Leaving it on does not harm the battery; if anything the lower heat helps the cells age more slowly in a Dubai office.
How many charge cycles should a new MacBook Air M4 have?
Under ten on the day you unbox it, visible in System Information under Power. A retail unit showing dozens of cycles has been used or sat on a display stand with the lid open. Keep a screenshot of the first reading; it helps if you need to claim under the return window.
Should I let the battery run flat to calibrate it?
No. Apple silicon Macs calibrate continuously through the battery management chip and a full discharge only adds a cycle and heat. Charge between roughly twenty and eighty percent when you can, leave Optimised Battery Charging on, and let the Mac finish its first day of indexing on mains power.
What are your workshop hours and locations?
We keep two Dubai workshops open to walk-ins. The Media City location is Office 45, 10th Floor, Concord Tower, closest for Marina, JLT, Al Barsha and Jumeirah. The Bur Dubai location is G 58, IT Center Building, closest for Karama, Deira and Downtown. Hours are Monday to Saturday, 09:00 to 19:00 with a Friday prayer break, Sunday closed. There is no collection service for repairs; walk in to either one.
