iphone battery life before replacement


Hey guys! It’s me, John, your friendly Scandi Tech support. In our years of selling high-quality batteries, we’ve encountered several people asking us why at certain times, their iPhone battery indicator bar turns yellow or orange. What most people don’t realize is that the yellow or orange indicator bar is actually a cool feature to save battery life.

We all know that batteries do not last forever but we can keep our batteries’ life last long enough for us to get home and charge it. How exactly do we do that? Well, for one thing, Apple added a setting in all iPhones that helps us manage battery use and keep our phones live longer between usage - this is the low power mode setting.

What is Low Power Mode and why does it turn my battery indicator bar yellow/orange?

Low Power Mode is a setting that can be manually activated or your iPhone will ask you if it should be activated when your battery reaches 20%. You can also adjust the setting to activate at higher levels to stretch out battery saving even more. This function also shuts off when your battery reaches 80% or if you turn it off manually in Settings > Battery > Low Power Mode on/off.

You’ll know that low power mode is activated when you see the battery logo change color. iPhone battery indicator turns to yellow or orange when this mode is activated alerting you that it is saving battery life. It’s as simple as that.

What does it do?

Low Power Mode basically deactivates or slows down certain functions in your device to save battery life. It disables/adjusts the following functions:

Brightness - It decreases screen brightness. While this can be adjusted independently, it is advised that the screen brightness is set on automatic to save battery life.

Auto-Lock - Low power mode decreases the time it takes to lock the device on idle. Therefore automatically shuts off the screen saving more life out of your battery.


Disables background app refresh - Background app refresh is considered huge battery hog. It works in the background by refreshing apps to keep itself updated. Examples of these apps are news apps, store apps, weather apps and etc. Low power mode completely disables this and you can get more life out of your battery until you can get your phone charged.

Disables auto-email update - By default, iPhone checks your email accounts for new mail. This will keep your phone consume that extra energy to download new emails for you but you can just disable it and just manually check your mail whenever you have the time to do so.

Slows down CPU - The big one. Low Power Mode forces your iPhone’s “brain” to consume less energy. This will relax your device and extend its battery life longer.

Other functions that Low Power mode deactivates are motion effects, animations, and Hey Siri.


It is advisable that this mode is activated but if you want to disable this function, here is how to do it:

Head to Settings > Battery and deactivate the “Low Power Mode” slider. The iPhone battery indicator in the status bar will turn red if the battery level is too low. If low power mode is activated, the battery bar turns yellow or orange and it can give you up to 2 hours of battery life. Still, this depends on your own usage.

Low Power mode is helpful when you find yourself in situations where it is virtually impossible to charge your device. Our phones are crucial to our day to day lives that saving battery life means so much.

So don’t be surprised if you see the iPhone battery indicator bar change to yellow or orange, this just means your phone is saving you more battery life.
