3 Always Update Your Device
Apple updates are an interesting thing, as they tend to change how the software and the hardware on your device interact. This is great news for your battery life, because it helps the software use the hardware more efficiently. That means that basic processes will take up less energy the more that you update. However, the reverse is true: If you hold back on updates, then processes and apps can take up more battery life than necessary, wearing your device out more quickly. So if you start getting update notifications, it’s time to plug it and let the upgrade happen ASAP rather than putting it off.
