Best Replacement Battery for iPhone 6s Plus

As we all know, smartphone batteries degrade over time when used, mainly as we recharge them, and iPhones are no exception. But luckily, you don't have to buy a new iPhone if you have a weak battery. Instead, you can easily replace it.

Why Replace An iPhone 6 Plus Battery?

If your iPhone 6Plus battery isn't as long-lasting as before, randomly shuts down when heavy apps are running, or iOS shows you your battery health isn't that great, you might need a new battery to extend your phone's life and effectiveness.

Last 2019, it was revealed that iOS versions from 10.2.1 onward reduce their peak performance on older iPhone models to prevent unexpected shutdowns on models with degraded batteries. According to Apple, these shutdowns cause older iPhones to draw more power than the battery can produce on a single occasion. The decrease in performance should only be initially noticeable when specific heavy apps are being used.

The iPhones 6Plus use lithium-ion batteries, which are similar to all smartphones, which are quickly degrading due to the battery's chemical components and are only designed to retain their battery to 80% of its original capacity. By replacing your old iPhone's battery, it restores the performance to normal, and your battery could last longer.

You can check your battery's health by following these steps (available on iOS 11.3 or newer versions):

1. Open the Settings app
2. Tap Battery and then Battery Health

It shows your battery's maximum capacity. If your iPhone's battery performance is being inhibited due to a reduced battery, you can disable it. Disabling the performance throttling can help prevent unexpected app crashes or shutdowns.
