Yes, you can turn off Optimized Battery Charging on your iPhone if you prefer your device to charge straight to 100% without delay. While this feature is designed to protect your battery’s long-term health, Apple gives users full control to disable or temporarily bypass it when needed.
In this article, we’ll explain how Optimized Battery Charging works, why it sometimes stops charging at 80%, how to turn it off (permanently or temporarily), and when it makes sense to do so.
What Is Optimized Battery Charging?
Optimized Battery Charging is a smart iOS feature that aims to reduce battery aging. Introduced in iOS 13, it uses machine learning to understand your charging habits and slows down the final phase of charging until just before you typically use your phone.
Why it’s helpful:
- Lithium-ion batteries age faster when kept at 100% for long periods, especially under high temperatures.
- Charging up to 80% quickly, then pausing, helps reduce the time the battery spends at maximum voltage.
- Your iPhone resumes charging to 100% just in time for when it thinks you’ll unplug it.
This process helps maintain higher battery health over months and years, delaying battery capacity loss and reducing the need for early battery replacements.
How to Tell If Optimized Battery Charging Is Active
When this feature is triggered, your iPhone will:
- Charge up to 80%, then pause.
- Display a message on the Lock Screen or Battery Settings that says:
“Charging paused: Optimized Battery Charging is active and will resume charging later.”
How to Disable Optimized Battery Charging
If you want your iPhone to charge to 100% immediately, you have two options:
✅ Option 1: Temporarily Turn It Off
Perfect if you just want a full charge once, such as during travel or a busy day.
Steps:
- When charging is paused at 80%, tap the “Charging paused” notification on your Lock Screen.
- Tap “Charge Now” to continue charging to 100% immediately.
OR
- Go to Settings > Battery > Battery Health & Charging
- Tap Optimized Battery Charging
- Choose “Turn Off Until Tomorrow”
This keeps the feature enabled but skips it for the next charge.
✅ Option 2: Permanently Turn It Off
Choose this if you don’t have a consistent charging schedule, or if you always want your iPhone to reach 100% without delay.
Steps:
- Open Settings
- Tap Battery
- Go to Battery Health & Charging
- Tap the toggle next to Optimized Battery Charging to turn it OFF
- Select “Turn Off” to confirm
Once disabled, your iPhone will charge directly to 100% every time—regardless of when or where you plug it in.
When Should You Turn Off Optimized Battery Charging?
🔹 Turn it off temporarily if:
- You’re traveling and need a full charge earlier than usual
- You’re changing routines and your iPhone’s charging predictions are off
- You’re about to attend a long meeting or leave home and need maximum battery
🔹 Turn it off permanently if:
- Your daily charging routine is inconsistent
- You charge in multiple locations (e.g., home, office, car) and iOS can’t predict your behavior accurately
- You use portable chargers or power banks frequently
- You don’t mind slightly faster battery aging in exchange for full charge convenience
Should You Leave Optimized Charging On?
In most cases, yes. Apple recommends keeping Optimized Battery Charging enabled for the following reasons:
- It helps reduce battery aging
- Keeps your battery health above 90% for longer
- Works automatically and improves over time as it learns your routine
This feature is especially helpful for users who charge overnight, as it prevents the battery from sitting at 100% for hours, which is a key contributor to chemical degradation.
Will Disabling It Hurt My Battery?
Turning it off occasionally or even permanently won’t damage your phone. However, over the long term, it may:
- Accelerate battery aging slightly
- Lead to a gradual drop in maximum battery capacity
- Reduce your iPhone’s overall battery lifespan, especially if you charge to 100% frequently and leave it plugged in
That said, if you take care to avoid overheating and follow other smart charging habits, the impact will be minimal for most users.
Pro Tips for Healthy Charging Without Optimized Charging
If you choose to disable Optimized Battery Charging, here are some best practices to help preserve your battery health:
- Avoid charging overnight unless using Optimized Charging
- Unplug at 80–90% if possible, especially if not in immediate use
- Keep your iPhone cool while charging—avoid direct sunlight or thick covers
- Use original or MFi-certified chargers only
- Don’t let the battery drain to 0% often; aim to charge between 20–80%
Summary
Yes, you can absolutely turn off Optimized Battery Charging on your iPhone if you want it to charge to 100% immediately. While the feature is designed to protect your battery over time, Apple gives you the flexibility to disable it temporarily or permanently depending on your needs.
Quick Takeaways:
- ✅ Optimized Charging pauses at 80% to reduce battery aging
- ✅ You can choose “Charge Now” or turn it off in Settings
- ✅ Best to keep it ON unless your routine requires full charges regularly
- ⚠️ Disabling it may lead to slightly faster battery wear over time
By understanding how this feature works and managing it wisely, you can strike the right balance between battery health and daily convenience.
