The ultimate MacBook battery guide

Best tips to save battery life on any MacBook, so that you can know how to maximise the battery life of your laptop!

  • Avoid keeping your MacBook in high ambient temperature environments (eg. a hot car).
  • Use a high-quality charger, eg. the stock MacBook charger or from a good brand.
  • It’s fine to leave MacBook attached to the charger 90% of the time.
  • Disconnect it occasionally and use the battery (eg. disconnect overnight, or use the battery until it drains to 10-15% (or 20-25%) every now and then.)
  • If you mainly use battery power, charge it in bursts (if you can) to keep the battery percentage between 20% and 80% (or the sweet spot to keep your battery charged is at between 25% and 85%).
  • Although the battery might say it’s at “100%”, in reality it’s actualy less than that. Apple designed the batteries this way with a “soft limit” to maximise longevity.
  • Even if you fail to follow any of these guidlines, you probably won’t experience a significant drop in battrey health due to modern li-ion batteries and software (with the exception of head and using a good charger).

Never discharge the battery below 10%

To take care of your devices with battery it is highly recommended that you recharge them when they are at 15-20% (or 20-25%) capacity. And of course, nothing happens if one day you completely drain the battery. The problem occurs when it is a repetitive action.

Store it half-charged when you store it long term

Do not fully charge or fully discharge your device’s battery — charge it to around 50%. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge. Conversely, if you store it fully charged for an extended period of time, the battery may lose some capacity, leading to shorter battery life.
