Want to check your iPhone's battery health? Follow these steps
Like all smartphones, the iPhones also use Lithium-ion batteries that degrade over time. As such, the performance of the devices may be throttled, leading to lags and slow-downs. Apple resorts to slowing down iPhones to prevent unexpected crashes and shutdowns due to the degraded battery, but you can avoid this by checking battery health and getting it replaced. Here's how you can do that.
How to check battery health?
In order to check battery health, head over to iPhone 'Settings' and tap on the 'Battery' option. From there, tap on the 'Battery health' option and check the amount of percentage showing next to 'Maximum capacity'. This percentage will show the state of your battery or how much charge it can hold. Don't confuse this capacity with the current level of your iPhone's battery.
As battery ages, its ability to hold charge declines
When an iPhone is new, its maximum capacity to hold charge will be at 100%, but with time and multiple charge cycles, this capacity falls down to 80-90%, even lower at times.
Degraded battery leads to throttling, but you can avoid that
If your iPhone's maximum battery capacity is lower than 80%, Apple will throttle the performance of the device to keep it from crashing and shutting down unexpectedly. You can disable throttling from the 'Performance management' option in the same 'Battery health' section, but that may trigger the problems of unexpected shutdowns. Also note, if your iPhone witnesses subsequent shutdowns, throttling will be re-enabled automatically.
Alternatively, you could go for battery replacement
Having said that, if you don't want to bear both these problems (performance management or unexpected shutdowns), we recommend going for the replacement. Apple has been offering replacements at lower prices and you can leverage this facility before December 31. If your iPhone is in need of a replacement, you'll see an alert for replacement under 'Peak performance capability' head in 'Battery health'.
