There are a lot of myths out there about how to extend iPhone 12 battery life. In order to truly take care of your device and prolong its life, use these tips and learn to tell fact from fiction.
How long does your battery last?
The lifetime of a iPhone battery is approximately 2-3 years, but that’s not to say that your iPhone 12 won’t last longer or shorter. A number of variables impact the life of your device’s battery.
Your iPhone’s battery life is determined by “charge cycles” not time. A charge cycle is determined by your device using a net 100% of its charge.
Most obviously, this is when you fully charge your iPhone to 100% and use it until it dies at 0%. However, a charge cycle also includes times when your iPhone is at 75% and you use it to 25% (a total of 50% charge) then charge it back to 100% and use it to 50% (another 50%).
A charge cycle is based on the total charge like a tank of gas. You can only fill the car to half a tank two times, but you still use a full tank of gas.
Regular usage of the device will go through the number of charge cycles in about 2-3 years. If you use your iPhone more than others, you may see a decline in charge length after a year to year and a half. If you use your iPhone less than other, you may see the batter life survive for three or more years.
However, manufacturers recommend that you upgrade your phone sometime between 2-3 years or if you notice a decline in the battery life of your device.

Should I let my iPhone 12 die to 0% before charging?
If the battery is based on charge cycles, then it doesn’t matter if the iPhone dies to 0% right?
Lithium-ion batteries degrade faster when forced to use their complete charge. Instead, charge your iPhone more often. Partial use of the battery will help the battery stay healthy. If you need a number to live by, try to keep the battery life above 30% if possible. That slight cushion could help your iPhone live longer.
Fast charging after the battery drops so low can harm it too. Use fast charging until around 80% then switch to a regular charge to avoid straining the battery.
Now that we’ve got that out of the way, what about tips for how to make iPhone 12 battery last longer? Are there other ways to preserve the battery life of your iPhone 12 other than using it less? Continue reading to learn how to make iPhone 12 battery last.

Is Leaving Your iPhone Plugged in Overnight Bad?
Leaving your iPhone plugged in overnight will NOT overload the battery and cause it to die faster or whatever you may have heard.
There is a built-in safety inside the iPhone that tells the phone to stop accepting a new charge when it’s full.
But… That’s doesn’t mean it’s harmless.
It only takes an hour to two hours to charge fully. After that, the iPhone stops charging until it falls to 99%. Then it starts charging again until 100%. Then it stops. Then it starts. See what’s happening? It’s called “trickling charge.”
All of that stopping and starting can actually wear on your battery. It contributes to the charge cycle life of your battery. Who’s to say that it is more or less than leaving your phone unplugged the entire night, but it can cause other problems.
Long Charging can Cause Overheating
The worry with charging your phone too long really boils down to overheating. The constant trickling charge that we described above can cause your iPhone to overheat, which can actually harm you, your device, and your furniture.
You may have seen the photos of mattresses or pillows that are charred from a charging phone. These photos are evidence of the trickling charge overheating a phone. Much like using a heavy blanket while lying in the hot sun, the phone overheats. With no way to dissipate that heat, the pillow or mattress catches on fire instead.
Prevent overheating iPhones with the tips below:
Stay away from using knock-off cables that may have bad connections or overheat easier.
Don’t place your iPhone under a pillow, blanket, or book that may cause it to overheat faster.
Remove your iPhone from the case to charge.
Place your iPhone in a dish or on something metal to dissipate heat.
Unplug the iPhone if you wake up at some point in the night or use a smart home outlet to schedule the charging to stop in the night.

Should I freeze my iPhone battery in the summer?
We’ve actually been asked this question before “My iPhone battery lasts longer in the winter. Should I freeze it in the summer?” Especially being close the beaches like we are, we’ve heard plenty of false recommendations that you should place your iPhone in a cooler in the summer to protect the battery.
There is some truth to this statement though. Leaving your iPhone out in the summer is a bad idea as the heat will harm your iPhone. However, BOTH extreme heat AND extreme cold can permanently harm your battery.
This applies to leaving the iPhone too close to the car heater or A/C vents. Be mindful of where you place your car mounts. Cranking the heat in the winter may cause the iPhone to overheat and harm your device. Likewise, keep the iPhone off the dash of the car in the summer as the banking sun will not do it any good.
NOTE: This applies to both a charging iPhone and a charged iPhone. Never let the iPhone overheat while charging, but also be incredibly mindful of the heat of the device while it’s not charging.

How do you make your iPhone 12 battery last longer?
If you’re looking for advice on keeping your iPhone 12 charged throughout a long day, then we have advice for that too.
For days when you’ll be away from your charger for a while, here’s a few tricks to keep your iPhone 12 charged longer.
Turn off or remove apps that drain the most power.
Some apps drain your battery faster than others. From experience, the Waze app drains my iPhone battery faster than I can charge it.
To preserve my iPhone 12 battery, I keep Waze turned off unless I need it AND I have a way to charge my device while I use the app.
To check which apps are using your battery the most:
On iPhone 12, select Settings > Battery. Here, you’ll find a breakdown of which apps used how much charge in the last 24 hours or 7 days.
Use these recommendations to adjust your habits on days you need the iPhone 12 battery to last longer. Things like turning the screen brightness down, avoid using certain apps and locking your iPhone while using maps will help your battery.
Turn off background apps and permissions.
Apps running in the background can drain the battery as they continue to run in the background.
Disable background app refresh on iOS to help your iPhone 12 last longer by navigating to Settings > General > Background App Refresh.
Turn off other iOS features
Other iOS features like Bluetooth, location sharing, Wi-Fi, and AirDrop can also drain your battery. Consider disabling Bluetooth when you aren’t using it or buying products that use Low Energy Bluetooth or BLE.
Likewise, only turn Wi-Fi and AirDrop on when you need it. Connecting to public Wi-Fi is dangerous for you and your device, so only connect at home or other private secured Wi-Fi.
Disable location settings on an app by app basis on iPhone 12 by going to Settings > Privacy > Location Services. We recommend leaving location settings on for weather apps, map apps, and some other location-based apps. Turn it off for games, messaging apps, and apps that don’t need to know your location to function. Consider switching the permissions to “While Using” whenever possible.
Final thoughts on how to prolong iPhone 12 battery life:
Most iPhones need to be recharged every couple of days if not every single day. There are ways to extend iPhone 12 battery life and many involve turning off services and features. One way to get ahead is to turn off background app refresh.
