I'd say it's a bit low for the cycle count, have you calibrated the battery regularly?

I haven't since last year. :/ I've been meaning to, but don't you have to keep it powered on for 2 hours, then drain the battery completely and then wait 5 hours to turn it back on? I've just not found the time yet, but I'll try to do that within the next day or two and see if that helps bring the numbers back up.

I'd suggest it, it will help keep your battery from degrading worse. :)

For reference the instructions are below.

MacBook Pro (all models), and MacBook Pro (17-inch) (all models)

The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) and any model of MacBook or MacBook Pro has been updated because of a new battery released with this computer. With these computers, follow these steps to calibrate your battery:

Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.

Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.

Disconnect the power adapter with the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, you will see the low battery warning dialog on the screen.

Continue to keep your computer on until it goes to sleep. Save all your work and close all applications when the battery gets very low, before the computer goes to sleep.

Turn off the computer or allow it to sleep for five hours or more.

Connect the power adapter and leave it connected until the battery is fully charged again.

  Charge Information:
  Charge remaining (mAh):	4879
  Fully charged:	Yes
  Charging:	No
  Full charge capacity (mAh):	4905
  Health Information:
  Cycle count:	70
  Condition:	Good
  Battery Installed:	Yes
  Amperage (mA):	0
  Voltage (mV):	12544

I did that overnight, and the numbers didn't improve -- is this normal and something I shouldn't worry about it?

Also, is it normal for the charger light to just go off and stop working? If I unplug it and plug it back into the laptop, it comes back on usually. If I ever get the chance to go to an Apple store, I thought about taking it in and asking, but I'm over 2 hours away from one.

Your battery is still showing in the 'Good' range so Apple won't replace it, however keep your eye on it closely to make sure you don't keep suffering major drops in capacity. It does look a bit low as I said though. :)

Happens to me all the time mate

Currently calibrating my new battery (which was replaced for free, thank goodness) for its first time :) yay! Hope this doesn't happen again for me, I plan on calibrating it regularly and using the battery more frequently to keep it going. The Genius said that keeping it plugged in for extended periods of time shouldn't do anything to the battery, but I plan on keeping it unplugged during times where I'm not around for more than a few hours (sleep, work, etc).

Thanks for all your help!

Truth be told I always have my MBP plugged in if I'm not truly mobile, no trouble ever. That being said, keep up on your calibrations and I think that battery will serve you well!

Glad everything was resolved for you!

Calibrate the battery.

There's some good tips in this thread. Is it advisable to leave my MacBook turned OFF over night, but plugged into the mains? The battery is already fully charged.

Once your Battery reaches approximately 95-98% it will halt charging and switch to the power adapter to prevent overcharge, doesn't matter if the machine is on or off. :)

    • This is about the EU given consumers options, Apple is all about not giving options and locking you into its own services, this hurts Apple far more than it hurts the EU market because it makes Apple products look less appealing by Apple refusing to offer its own service because they have to give options to rivals, the end results are consumers might look at alternatives like Android. It's a game Apple can't really win when there are alternatives and Apple will in time change course on this, until then, let Apple hurt themselves in the EU market.
    • Microsoft unveils new Surface Laptop with improved trackpad, Snapdragon X2, and more by Taras Buria Microsoft's new Surface Laptop Ultra generated a lot of buzz earlier this month, but in addition to its most powerful laptop with an NVIDIA chip, Microsoft also has a more affordable laptop lineup, which has been waiting for an update for quite a while. Today, Microsoft announced the eighth-generation Surface Laptop. The new Surface Laptop is powered by the Snapdragon X2 Plus and X2 Elite processors. These chips offer faster CPU performance, up to 58% faster graphics, and 80 TOPS Neural Processing Units (NPUs) for on-device AI processing. Like the previous models, these chips retain their great energy efficiency, and Microsoft says that buyers can expect up to 20 hours of work on a single charge. The laptop is available in two sizes: 13.8-inch and 15-inch. You will have a hard time finding visual differences between the new and previous models, as Microsoft is not taking any major design leaps, except for the new Jade color, which may look familiar to Surface Laptop 5 owners. Other colors include Platinum, Black, and Dune. The 15-inch variant got a higher-resolution display. It is a 3,270 x 2,180 resolution screen with a pixel density of 262 ppi (the 13-inch model has a 201 ppi density) and a maximum brightness of 600 nits SDR and HDR. Unlike the Surface Pro 12th-gen, which is available with optional OLED displays, the Surface Laptop sticks with IPS, a 1,300:1 contrast ratio, a 120Hz refresh rate, and a 3:2 aspect ratio. Another notable change in the Surface Laptop 8 is its trackpad. It now provides haptic feedback when you perform various actions in apps and the operating system. It is a relatively new feature that Microsoft brought to Windows 11 in recent updates, and it is only available on certain devices, such as the Logitech MX Master 4, Surface Slim Pen 2, the upcoming Surface Laptop Ultra, and now the Surface Laptop 8. The new Surface Laptop with the new Surface Pro Like its tablet-shaped sibling, the new Surface Laptop is notably more expensive. It starts at a $1,599 for a 13.8-inch configuration with a 256GB SSD and 16GB of RAM. However, in the US, the base model has double the storage while keeping the same price. Available configurations include up to 64GB of memory and up to 2TB SSD (user-removable PCIe Gen4). The Surface Laptop 8 is now available for purchase on the official Microsoft website.
    • Microsoft announces 12th-gen Surface Pro with Snapdragon X2 processors by Taras Buria So far, 2026 has been rich in Surface announcements. Microsoft started with a fresh lineup of Surface for Business devices powered by Intel's new Core Ultra 300 processors. Then the company revealed the Surface Laptop Ultra, its most powerful laptop with NVIDIA's RTX Spark processor. Now, it is time for new Surface Pro and Surface Laptop models with Qualcomm processors. Microsoft's original Copilot+ PCs with Snapdragon X1 chips debuted in late May 2024. Two years later, Microsoft is finally updating the lineup with new models featuring Snapdragon X2 processors. The 12th-gen Surface Pro continues the well-established formula of Microsoft's flagship tablet, and Microsoft is not even changing colors, as the tablet will be available in three colors: Dune, Black, and Platinum. The most important changes are mostly hidden inside. Microsoft switched from the Snapdragon X1 to the new Snapdragon X2, which promises up to 53% faster graphics performance than the previous generation and up to 15.5 hours of battery life. The built-in NPU is also much more powerful, and it can run at up to 80 TOPS for on-device AI processing. Like before, the new Surface Pro is available with a 13-inch IPS display, and Microsoft is still offering OLED as a separate, more expensive configuration. Speaking of configurations, the Surface Pro will be available with a 10-core Snapdragon X2 Plus or a 12-core Snapdragon X2 Elite. Microsoft expanded the available RAM configurations to 64GB (previously 32GB was the maximum), while storage remains unchanged at 256GB, 512GB, or 1TB of user-replaceable PCIe Gen4 SSDs. The new Surface Pro and the Surface Laptop Other specs remain mostly unchanged. The computer has the same 1440p Windows Hello webcam, two USB4 ports for charging, data, and display output, Wi-Fi 7 and Bluetooth 5.4 support, dual speakers, and compatibility with Surface Pro Signature and Flex keyboards. With that said, there is one very important aspect of the Surface Pro that changed significantly, and it is the price. While the previous-gen Surface Pro launched at $999 for the base configuration, in 2026, the entry-level Surface Pro with Snapdragon X2, 16GB of memory, and 256GB will set you back an eye-watering $1,499. To sweeten the pill, Microsoft is running a limited-time promotion where Surface Pro buyers can get a free Surface Pro 13-inch Keyboard. The promo runs from June 16 through June 30. The new Surface Pro is available now on the official Microsoft Store website.
