All about iPhone & iPad battery health – Back Market - Help Center - USA

Help your iPhone or iPad battery live its longest, healthiest life with these tips from our in-house tech wizards.

What are Back Market’s battery standards?

All devices sold on Back Market will arrive with a battery health of at least 85%. For smartphones, you can also choose one that comes with a brand-new battery.

If you purchased a phone with a brand-new battery, your device must have a charging capacity of 100% when you receive it. If the battery capacity falls below 90% after the first 30 days of use or anytime thereafter up until the end of your twelfth consecutive month of use, you’re entitled to a repair.

1-year warranty and Quality Charter battery details
After six months of purchase, battery health issues aren’t covered by the warranty, as it's normal for batteries to degrade when used.

For devices without new batteries, keep in mind that if your battery health is above 85% within the first month of purchase or 80% within the first 6 months, the state of its battery complies with our Quality Charter. This applies to smartphones purchased across all condition grades.

How do I check my battery health?

A normal battery is designed to keep up to 80% of its capacity for 500 complete charge cycles if operated in normal conditions, according to Apple. To check your battery health, follow these steps.

Go to “Settings” > “Battery” > “Battery Health” > check the percentage next to “Maximum Battery Capacity”.

If the capacity is 80% or above, your battery is in good health.

Keep in mind that when your battery is replaced by someone outside of Apple, your phone will show a notification that reads “Unknown part” or “Important Message.”

Don’t panic — this is completely normal and doesn’t affect your device’s performance. Learn more about “Unknown part” or “Important Message” notifications

How do I check my battery usage?

It’s important to get into the habit of checking your battery usage. It’s a great way to monitor how much power your apps and software use.

To determine your device’s battery usage, go to “Settings” > “Battery” and look for the following sections.

Battery Health & Charging

You can learn about your patterns of use and what drains your battery from these insights. Your device might also give suggestions to help you lower your energy consumption. If available, select the suggestion and you’ll automatically be brought to the setting.

Last Charged to

This shows you the battery level of the last time your device was charged and disconnected.

Battery Level graph (last 24 hours)

This shows you the periods of time when your device was in Low Power Mode or running out of battery. It also shows your battery levels and charging intervals.

Battery Activity graph (last 10 days)

This shows your battery usage and activity for the last 10 days. It also tells you how long your screen was either on or off in that time period.

Background Usage by App

Understanding the background activity of your apps is really helpful. It can help you manage your battery usage by showing how much of your battery is used by each app. Keep in mind that you won’t be able to see this while your device is charging.

The first step is to restrict apps from refreshing in the background. Just follow these steps:

Step 1. Go to “Settings.”

Step 2. Select “General.”

Step 3. Select “Background App Refresh”.

Step 4. Select “Wi-Fi”.

Step 5. Select “Wi-Fi & Cellular Data”.

Step 6. Select “Off”.

How can I get the most out of my battery?

Update your device

You should always use the latest iOS version to maximize your device's performance. You can make sure your device is updated by going to “Settings” > “General” > “Software Update”.

Change your brightness settings and rely on Wi-Fi

The best way to optimize your device’s performance is to keep your screen brightness low and use Wi-Fi when you can.

You can also enable auto-brightness. To do so, go to “Settings” > “Accessibility” > “Display & Text Size” > “Auto-Brightness” > “On”.

Adjust your Mail app

You can also adjust your Mail settings to determine how often the app loads new emails. Just go to “Settings” > “Mail” > “Account” > “Fetch new data” and choose between these settings:

Automatically
Manually
Hourly
Every 30 Minutes
Every 15 Minutes

Turn off Siri suggestions

Siri automatically runs in the background in order to send you recommendations. This drains your battery more quickly, so unless you really rely on her — it’s time for Siri to go.

Go to “Settings” > “Siri & Search” > “Suggestions From Apple”.

Then, disable notifications, sharing, and listening suggestions.

Turn on Low Power Mode

Low Power Mode is a very useful feature that makes your battery life last longer. Low Power Mode helps maximize your device’s performance by reducing brightness and minimizing animations among other things.

When your battery level reaches 20% or 10% a pop-up message will appear to turn it on. Once your device is charged again, Low Power Mode will automatically turn off.

You can also enable this in Settings. Go to “Settings” > “Battery” > toggle the button next to “Low Power Mode”.

Location and background location

When you allow apps to use your location, it can consume a lot of battery in the background. To adjust this, go to “Settings” > “Privacy” > “Location Services”.

Once there, you can see a list of apps that use your location. Choose which ones you want to turn off.

Reduce push notifications

If any app sends you too many notifications, you can turn them off by going to “Settings” > “Notifications”, scrolling to find the app in question, and then toggling off “Allow Notifications”.

Turn on Airplane mode

You can do this when you don’t need to receive texts, make calls, or search the internet. You can easily turn it on via your control panel. Airplane mode shows up as the plane icon — just select it to turn it off. You can also do so in your settings.

What are some easy ways to extend battery life?

There are several best practices that can extend your device’s battery life and help the charge last longer.

Keep it cool

Avoid situations that can cause your device to overheat — this is particularly important when it’s fully charged. Your battery will run out a lot faster when it’s hot out, even if you aren’t using it.

It’s important not to expose your phone to temperatures above 35°C (95°F) as this can permanently damage the battery.

You should also stay away from cases and accessories that may cause your device to overheat.

Optimize your settings to save your battery

You can adjust the following settings on most devices:

Enable the automatic screen-lock feature, which turns off your screen when it’s not in use.
Turn off sounds or vibrations, such as the keyboard.
Leave your apps open — reopening them uses a lot of battery.
Reduce the usage of apps that consume a lot of battery.
Turn off Bluetooth.
Delete any apps you don’t use.
Place your device facing down while you aren’t using it — this will stop the display from lighting up when you receive a notification.
Activate dark mode.

Charge your device only as needed

Contrary to popular belief, phone batteries don’t need to be charged to 100%. Don’t make your battery work harder than it has to follow these tips:

Ideally, your phone should always be charged between 20% and 80%.
Don’t charge your phone to 100% unless absolutely necessary.
Don’t allow your battery to drain to 0% and turn off.
Don’t leave your device without a charge for too long.
Prioritize small charges — 20% at a time multiple times a day is best.
Consistently update your apps.
