Battery & power tips for MacBooks - get more from every charge.
Your MacBook's battery is smarter than you might think, and so are the tools built in to look after it. A few small habits, and knowing where to look when something feels off, make a real difference to how long a charge lasts and how healthy the battery stays over the years. None of this needs new software or gadgets - it is all sitting in System Settings already.
1. Turn on Low Power Mode - it's better than you think.
Low Power Mode is one of the most useful, most ignored settings on any Mac. It trims background activity and a few visual effects to squeeze extra hours from a low battery, and on Apple Silicon Macs it barely affects everyday use. You do not need to wait until you are nearly empty either - plenty of people leave it on permanently while working away from a plug.
→ Turn it on from Control Centre - click the battery icon, or go to System Settings > Battery > Low Power Mode.
→ Set it to 'Only on Battery' so it switches on automatically the moment you unplug.
→ Don't worry about video calls or exports - it barely touches performance on Apple Silicon Macs.
→ It works just as well on a MacBook that stays plugged in - it simply throttles a little to run cooler.
2. Check your battery's health, not just its charge.
Every MacBook battery quietly tracks its own condition, and Apple makes that information easy to find. Head to System Settings > Battery > Battery Health to see the maximum capacity compared with when it was new, plus its current condition. A battery that has dropped a lot, or shows 'Service Recommended', is still safe to use - you will just notice shorter run times.
→ System Settings > Battery > Battery Health shows Maximum Capacity as a percentage.
→ Anything above about 80% after a couple of years of daily use is entirely normal wear.
→ 'Service Recommended' means book a check, not panic - the Mac is still perfectly usable.
→ Cycle count matters more than age - a battery charged occasionally lasts longer than one drained daily.
3. Find out what's actually draining your battery.
Before blaming the battery itself, it is worth checking what is using it. Activity Monitor's Energy tab ranks every app by how much power it is drawing right now, and it is often something surprising - a browser tab playing video in the background, or an app that never properly closed. Screen brightness and background app refresh are the two biggest everyday culprits, and both are easy to rein in.
→ Open Activity Monitor (Cmd+Space, type 'Activity Monitor') and click the Energy tab to sort by usage.
→ Turn brightness down a notch or two - it is the single biggest drain on any laptop screen.
→ System Settings > General > Background App Refresh - turn it off for apps you don't need updating constantly.
→ Close browser tabs playing video or audio you're not watching - they keep the Mac awake.
4. Charging habits that actually help - and myths that don't.
Optimised Battery Charging learns your routine and holds charge at around 80% until shortly before you normally unplug, so the battery spends less time sitting at 100%, which is what accelerates wear. You do not need to run it flat before charging, and you do not need to unplug the moment it hits 100 - the Mac manages all of this for you. Heat is the real enemy, so avoid charging under a hot bag or in direct sun.
→ System Settings > Battery - check Optimised Battery Charging is switched on.
→ There's no benefit to letting a modern MacBook run down to 0% - little and often is fine.
→ Keep it cool while charging - heat ages a battery faster than charge cycles do.
→ Genuine or MFi-certified chargers and cables avoid the slow, silent damage a poor cheap one can cause.
• Low Power Mode is safe to leave on permanently, not just an emergency setting.
• Battery Health in System Settings tells you the real story - check it every few months.
• Screen brightness and Background App Refresh are the two easiest wins if a battery seems to drain fast.
• There's no need to fully charge or fully drain a modern MacBook battery - little and often wins.
• If you're reading this through your employer's TechBenefits scheme, every one of these tools comes standard on the Mac you were supplied - no extra apps needed.
