Reminder: If your device's battery health is above 85% within one 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 in all aesthetic conditions.
After six months of purchase, battery health issues are not covered by the warranty, as it's normal for batteries to degrade when used. Please contact Back Market Customer Care if your device’s battery is below the percentages above when you receive it.

1/4 - Check your battery health first
- 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
According to Apple, a normal battery is designed to retain up to 80% of its capacity at 500 complete charge cycles if operated in normal conditions. At Back Market, we work to make sure that you receive a functional device, which is why our Quality Charter follows these recommendations.
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 “Warning message.” Don’t panic — this is completely normal and doesn’t affect your device’s performance.

Activity and Battery Usage by app.
Here you can manage your battery life according to the proportion of battery used by each app. You won’t be able to see this when your device is charging.
Background Activity. Here you can manage your battery life according to the proportion of battery used by each app. You won’t be able to see this when your device is charging.
- To optimize your battery life, restrict apps from refreshing in the background.
- To do so head to Settings > General > Background App Refresh
- Select Wi-Fi > Wi-Fi & Cellular Data > Off
Location and Background Location.
This section refers to apps that use your location.

Home & Lock Screen. This happens when the Home or Lock screen displays on your device. Most of the time is due to notifications or pressing the Home button.
If any app pushes many notifications, you can turn them off for the app by clicking on Settings, and then Notifications. Select it and put Allow Notifications off.
No Cell Coverage/Low Signal. When you are located in an area with low coverage, your device looks for better signal, which reduces your battery life. You can optimize it by turning on Airplane mode, in the Control Center (plane icon), or in your Settings.
3/4 - Make the most out of your device
Good to know: “Battery Life” refers to how long your device runs before it needs to be recharged. “Battery Lifespan” is the amount of time your battery can last until it needs to be replaced. Below we’ve compiled a list of ways you can make the most out of your device!
Update your device.
You should always use the latest iOS version to maximize your device's performance:
- Always check for updates: go to Settings > General > Software Update
- If there is one available, you can update it wirelessly:
- Plug your phone into a trusty power source or simply connect it to your computer and use the latest version of iTunes to perform the update
Change the settings.
The best way to optimize your device’s performance is to adjust your screen brightness and use WiFi when you can.
Keep the brightness low via the Control Center — use your finger to lower the white section to the bottom of the rectangle
Go to Settings > Accessibility > Display & Text Size > Auto-Brightness > On
WiFi connections always use less battery than normal cellular data and so we recommend using WiFi whenever possible!
You can also adjust your Mail setting to determine how often the app loads new emails.
- Go to Settings > Mail > Account > Fetch new data
Choose between various settings to Fetch New Data:
- Every 30 Minutes
- Every 15 Minutes.
We also recommend turning off Siri suggestions. Siri automatically runs in the background in order to send you daily recommendations. This will drain your battery more quickly.
- Go to Settings > Siri & Search > Suggestions From Apple
- Here you can 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. Once your device is charged again, Low Power Mode will automatically turn off.
When your battery level reaches 20% or 10% a pop-up message will appear to turn it on. You can also enable this in Settings.
- Go to Settings > Battery
- Toggle the white button next to “Low Power Mode” so that it turns green
4/4 - The best routine for your battery
There are several best practices that can extend your device’s battery life and help the charge last longer. Below are even more suggestions to help improve your battery’s performance so that you get the most out of your device!
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 very important not to expose your phone to temperatures above 35°C (95°F) as this can permanently damage the battery. When storing your device when not in use, we recommend that you keep it in a place with temperatures between -20°C (-4°F) to 45°C (113°F).
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 for what you need
Contrary to popular belief, phone batteries don’t need to be charged to 100%:
- 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
