Best Apps to Check MacBook Battery Health (2025)
Your MacBook’s been acting like a moody teenager lately—shutting down unexpectedly, draining faster than a bathtub with the plug out, or showing that dreaded “Service Recommended” message?
As Auckland’s go-to MacBook repair experts at SMASHED IT, we’ve seen every battery drama imaginable, from Ponsonby professionals whose MacBooks die mid-Zoom call to Parnell students whose devices won’t last through a single lecture.
Here’s the thing: while your MacBook gives you basic battery info, it’s about as detailed as a weather forecast that just says “might rain.”
If you want the full story on what’s happening under the hood, you need the right battery health apps.

Why You Need More Than macOS’s Basic Battery Info
Apple’s built-in battery indicator is like getting health advice from your mate Dave—technically correct but missing the juicy details.
Sure, it’ll tell you when your battery needs servicing, but it won’t explain why your MacBook Air is guzzling power like a V8 ute or whether that “Normal” status is actually normal for a three-year-old laptop.
For Auckland MacBook users dealing with our humid summers and air-conditioned offices, understanding your battery’s real condition can mean the difference between a device that lasts the workday and one that leaves you scrambling for a charger during that crucial client presentation in central Auckland.
Top MacBook Battery Health Apps: The Essential Lineup
Not all battery apps are created equal—some are like getting advice from a know-it-all mate, while others are proper diagnostic tools.
We’ve tested dozens of apps on everything from 2015 MacBook Airs to the latest M4 MacBook Pros, and these five stand out as the cream of the crop for Auckland users who want real insights, not just pretty interfaces.
1. coconutBattery 4 – The OG Battery Detective
Price: Free (Plus version $15.54 one-time)
Best for: Data nerds who want ALL the details
coconutBattery has been the gold standard since 2005—basically ancient history in tech years. This app doesn’t just tell you your battery percentage; it gives you the full CSI treatment with temperature readings, exact capacity in milliamp-hours (mAh), manufacturing date, and even your battery’s serial number.
What sets it apart:
- Monitors your iPhone and iPad batteries too (handy for those multi-device Kiwis)
- Historical data tracking (Plus version)
- Battery lifetime analyzer showing max/min temperatures
- Works with both Intel and Apple Silicon Macs
The catch: Some users reckon coconutBattery’s readings don’t always match macOS exactly—it might show slightly different capacity numbers, especially if you’ve got Apple’s optimized charging turned on. Think of it as getting a second opinion from a different doctor.
2. Battery Monitor – The Free Champion
Price: Completely free
Best for: No-nonsense monitoring without the subscription trap
Sometimes the best things in life really are free. Battery Monitor delivers all the essential info in a clean, easy-to-read interface that won’t have you squinting at tiny numbers. Perfect for Auckland tradies or busy professionals who just want the facts without the fuss.
Key features:
- Current charge and cycle count
- Temperature monitoring (crucial for our humid climate)
- Time remaining estimates
- Configurable alerts for low battery
Why Aucklanders love it: It’s accurate, reliable, and doesn’t try to upsell you every five minutes. Plus, it replaces that boring battery icon with something actually useful.
3. iStat Menus 7 – The Swiss Army Knife
Price: $11.99 (14-day free trial)
Best for: Power users who want system-wide monitoring
iStat Menus is like having a full medical checkup for your Mac. While its battery monitoring is excellent, you also get CPU, memory, network, and temperature monitoring—perfect for Ponsonby MacBook users juggling creative work or data analysis.
Standout features:
- Shows which apps are battery vampires
- Monitors Bluetooth accessory batteries (Magic Mouse, AirPods, etc.)
- Minimal system impact despite comprehensive monitoring
- Highly customizable displays
Pro tip: Buy directly from the developer rather than the Mac App Store to get full functionality, including fan speed control.
4. AlDente – The Control Freak’s Dream
Price: Free (Pro version $12/year or $25 lifetime)
Best for: Users who want precise charging control
AlDente is for those who want to micromanage their battery like a helicopter parent. Its claim to fame? You can set your MacBook to stop charging at any percentage, not just Apple’s default 80% optimized charging.
Advanced features (Pro version):
- Automatic discharge to target levels
- Heat protection (pauses charging if temperature gets too high)
- “Sailing Mode” maintains charge in narrow ranges
- Calibration mode for accuracy
- Integration with Shortcuts app
Perfect for: Central Auckland office workers whose MacBooks live plugged in all day, or anyone wanting to maximize battery lifespan.
5. Battery Health 2 – The User-Friendly Option
Price: Free (Power History $9.99 in-app purchase)
Best for: Casual users wanting essential info with a nice interface
Battery Health 2 strikes a nice balance between simplicity and detail. It shows current and original capacity, cycle count, battery age, and power usage in an interface that won’t intimidate your nan.
Notable features:
- Clear capacity comparisons (current vs. original)
- Useful notifications about battery status
- Power History graphs (paid feature)
- Works on older Mac systems
The downside: Some features from the original version are missing, and the Power History feature requires an additional purchase.
Free vs. Paid: What’s Worth Your Hard-Earned Dollars?
- Start with free options: Battery Monitor gives you everything most Auckland MacBook users need without opening your wallet. It’s accurate, reliable, and doesn’t collect your data for targeted ads.
- Upgrade if you need more: coconutBattery Plus ($15.54) is worth it if you want historical data and iOS device monitoring. AlDente Pro ($25 lifetime) makes sense for heavy users who want granular charging control.
- Skip the subscriptions: Unless you’re a professional who absolutely needs real-time monitoring, monthly subscriptions for battery apps are like paying for premium air—unnecessary for most folks.
