How Long Should My iPhone Battery Last?
At Shiny Apples this is one of the most common questions we get asked, how long should my iPhone battery last?
We should mention that “battery life” and “battery lifespan” mean two seperate things, “Battery Life” means the amount of time your device can be used before it needs to be recharged. Now “Battery Lifespan” means the amount of time your battery needs before it has to be replaced.
How many charge cycles will I get?
According to Apple, they advise that an iPhone battery will retain 80% of its capacity after 500 full charge cycles, this would equate to 1.3 years if you charged it once daily.
The above suggests that your battery will just reduce its original battery capacity, in theory your battery should still operate and charge but you will see your “Battery Life” drop so you don’t get as much use out of it compared to when it was new.
When should I replace my battery?
There is no set pattern or rule for this, we have seen batteries that needed to be replaced not far being over one year old, others have gone on for 2+ years.
We always suggest that a customer use the iPhone until it becomes a problem, this might be when your are getting little battery life between charges, you have to charge the iPhone 2-3 times a day.
When things get really bad, you might notice that the iPhone powers off when it says 20-30% battery remaining, when this happens this can create a bad user experience and catch you out leaving you without an iPhone to use!
Let’s face it, batteries won’t last forever, they will eventually die and will need to be replaced.
This is why I say, use the iPhone until you notice it becomes a problem, I do advise however if your iPhone does power off when it says you have battery power left then this is the battery giving you a warning “replace me!”
Can a bad battery cause damage to my iPhone?
During the course of our repairs we have seen batteries swell up, these have split and leaked inside devices, we have seen these swell up causing damage to the iPhone screen.
We recall one repair where the battery swelled that much it pushed the iPhone screen up and damaged the LCD screen from the pressure built up inside the iPhone.
If a battery expands, swells up, it needs to be removed and replaced without any delay.
can I do anything to help my battery lifespan?
We strongly advise keeping your iPhone out of temperatures exceeding 35 degrees celcius, not normally a problem in the UK.
Leaving your iPhone in direct sunlight, on the dashboard of your car is not advisable as this can cause permanent damage to your battery.
Make sure you update the iOS software, Apps, and use WiFi over cellular when possible, reduce your screen brightness when possible or use auto brightness to adjust the screen brightness.
Just remember, your iPhone battery can be replaced to give it a new lease of life, batteries don’t last forever and they will need replacing at some point.
