Apple added the ability for users on iPhone 7 devices and below to see their battery health and better manage their battery consumption with iOS 11.3. The addition of the feature originated towards the end of 2017 when Apple admitted to throttling older devices. This was done to boost the hardware life of these devices and prevent overheating due to old batteries. With iOS 12.1, it seems that Apple has now extended the feature to include 2017’s flagship phones which include iPhone 8, iPhone 8 Plus and iPhone X.
For many years, people had crazy theories that Apple was deliberately slowing down devices with each iOS update. There was speculation that this was done so that more consumers would be encouraged to buy new iPhones every year. It wasn’t until the end of 2017 when Apple admitted to slowing down older devices with each new update, but with good reason.
Apple stated that this was done to protect phone hardware. The company faced a lot of backlash for this. Since then, they have apologized by offering replacement batteries at affordable prices at Apple Stores. The feature originally rolled out for iOS 11.3 but only covered the following devices:
- iPhone 6
- iPhone 6 Plus
- iPhone 6s
- iPhone 6s Plus
- iPhone SE
- iPhone 7
- iPhone 7
You can see that Apple’s 2017 line-up of phones is absent from this list. iOS 12.1 officially released a few days ago and added battery management to these devices:
- iPhone 8
- iPhone 8 Plus
Battery management in iPhone X with iOS 12.1
Battery management allows the phone to follows Apple’s parameters to ensure a good balance of battery life and hardware functionality. There is a performance management feature that turns itself on after the first unexpected shutdown, which happens when battery health is less than 80%. This is the first sign that your iPhone is experiencing problems. You can disable the feature but it is highly ill-advised.
The feature also shows you which app is consuming the most power. This is good for learning how to increase the battery life on the phone. If you are on older phones, Apple advises you to keep performance management on and monitor battery health. As soon as you’re alerted to an ‘important battery message’ or ‘battery health degraded’ notification, get the battery replaced immediately.
You can read all about iPhone batteries and details surrounding it in Apple’s relevant support article. If you’re a tech-savvy iPhone user, this is definitely a good read for you and important knowledge to pass on to others.
With the help of battery management, users can have near total control of their power consumption. Users can check statistics to know when their battery needs changing. They can monitor battery drain time and other metrics to check device efficiency throughout the day.
Apple warns to only opt for battery replacement through official channels. Any Apple Store or Authorized Apple Service Center (AASP) is qualified to handle the task. Newer devices have less to worry about since the battery takes a long time to show age. Older devices will show signs faster by spotting odd behaviors like random reboots frequent phone freezes and crashes.
