Load In Smart is a power-saving feature that delays when your device charges
Load In Smart is a charging setting that holds off on powering your battery to a full charge until you actually need it. Instead of charging to 100% the moment you plug in, the device waits — sometimes for hours — then finishes the charge closer to when you typically unplug and leave. The goal is to reduce the time your battery spends at maximum charge, which slows down battery aging.
You'll find this feature on iPhones (called "Optimized Battery Charging"), some Android phones, and laptops from manufacturers like Lenovo and Dell. The names vary, but the idea is the same: keep your battery healthier by not leaving it fully charged longer than necessary.
Key Takeaways
- Load In Smart delays charging to 100% until shortly before you typically wake up or unplug your device, reducing how long the battery sits fully charged.
- Batteries degrade faster when held at full charge for long periods, so this feature extends the overall lifespan of your battery by months or years.
- You can usually turn Load In Smart on or off in your device's battery settings, and you can override it by unplugging and replugging if you need a full charge when ready.
- The feature learns your daily routine — when you charge, when you leave, when you wake up — so it works better the longer you use it.
How Load In Smart learns your charging habits
When you first turn on Load In Smart, your device does nothing special — it charges normally. Over the next week or two, it watches when you plug in, when you unplug, and what time of day you typically leave home or wake up. It's looking for patterns, not tracking you across the internet.
Once it has enough data, the feature starts holding your charge at 80% or so until it predicts you'll need the full battery. If your device learns that you always unplug at 7:30 a.m., it will finish charging to 100% around 7:15 a.m. If you charge overnight and leave at 8 a.m., it waits until around 7:45 a.m. to top off.
The prediction isn't perfect — weekends and travel throw it off — but it gets better as it collects more data. If your routine changes (you start leaving earlier, or you charge at different times), the feature adjusts.
Why batteries degrade faster at full charge
A lithium battery's chemical reactions are most aggressive when the battery is at 100%. The higher the charge level, the more stress the battery chemistry experiences. Keeping a battery at full charge for hours or days accelerates this wear, which is why phones and laptops lose capacity over time.
The difference is measurable. A battery that spends most of its time between 20% and 80% will retain more capacity after two years than one that regularly sits at 100%. Load In Smart exploits this by keeping your battery in the safer middle range as much as possible, only topping it off when you're about to use it.
This is why many manufacturers now recommend keeping devices plugged in overnight with Load In Smart enabled, rather than unplugging them at night. The feature does the work of protecting the battery for you.
How to turn Load In Smart on and off
On an iPhone, go to Settings > Battery > Battery Health & Charging and toggle on "Optimized Battery Charging." The feature is usually on by default on newer models.
On Android, the location varies by manufacturer. Samsung calls it "Adaptive Battery" or "Adaptive Charging" and it's in Settings > Battery and Device Care > Battery. Google Pixels have "Adaptive Charging" in Settings > Battery > Battery Saver. Lenovo and Dell laptops often have it in their power management software, usually accessible from the system tray or Settings > Power.
If you need a full charge right now — before your device predicts you'll need it — you can usually override Load In Smart by unplugging and replugging the charger, or by manually disabling it temporarily in settings. Some devices will also charge to 100% when ready if the battery is critically low.
When Load In Smart might not work as expected
Load In Smart relies on routine. If you travel frequently, charge at wildly different times, or use your device unpredictably, the feature may not learn a clear pattern. It might charge to 100% when you don't need it, or hold at 80% when you're about to leave.
The feature also assumes you'll plug in regularly. If you go days without charging, or if you use your device so heavily that the battery drains before the predicted charge time, Load In Smart can't protect the battery the way it's designed to.
In rare cases, the feature can cause confusion: you plug in expecting a full charge and find yourself at 80% an hour later. If this happens repeatedly, you can turn it off and charge normally, though you'll lose the battery-protection benefit.
Load In Smart versus other battery-saving features
Load In Smart is different from Battery Saver mode, which limits your device's performance to reduce power drain. Load In Smart only affects charging; it doesn't change how your device runs. You can have both on at the same time.
It's also different from fast charging, which is about how quickly the battery fills up. Load In Smart is about when the charging happens, not how fast it happens. Some devices combine both — they charge quickly to 80%, then slow down for the final 20% to reduce heat and stress.
If your device has a "health mode" or "battery protection mode," that's usually Load In Smart under a different name. Check your device's battery settings to see what options are available.
How much longer does Load In Smart actually extend battery life
The exact improvement depends on how much you charge and how you use your device. If you charge overnight every night and use your phone all day, Load In Smart might add 6 to 12 months of usable battery life over two years. If you charge multiple times a day or leave your device plugged in constantly, the benefit is larger.
The improvement is most noticeable after 18 to 24 months of use. A phone with Load In Smart enabled might retain 85% to 90% of its original battery capacity after two years, while one without it might drop to 75% to 80%. That's the difference between a phone that still feels responsive and one that needs a battery replacement.
The exact numbers vary by device, battery chemistry, and how much you use it. But the direction is always the same: Load In Smart slows down battery aging.
Frequently Asked Questions
Does Load In Smart slow down charging?
Not in the way you might think. The feature doesn't make charging slower when it does happen — it just delays when charging starts. You still get a full charge in the same amount of time; it just happens later. If you need a full charge when ready, you can override it.
Will my device tell me if Load In Smart is holding my charge?
Most devices show a notification or indicator when Load In Smart is active. On iPhones, you'll see a note in the battery settings. On Android, it depends on the manufacturer, but Samsung and Google both show indicators. Check your battery settings to confirm it's on.
Can I use Load In Smart if I charge my device multiple times a day?
Load In Smart works best with a predictable charging routine, so it may not be as effective if you charge at random times. It will still try to learn your patterns, but the protection benefit is smaller. If you charge unpredictably, turning it off won't hurt — just be aware that your battery will age faster.
What happens to Load In Smart when I travel?
Load In Smart may not work well during travel because your routine changes. Many devices will revert to normal charging or take time to learn a new pattern. Once you return to your normal routine, the feature will readjust over a few days.
Does Load In Smart work if I leave my device plugged in all the time?
Yes. Load In Smart is designed for this scenario — it keeps your battery at 80% most of the time and only tops it off when it predicts you'll unplug. This is actually one of the best ways to use the feature, since your battery spends most of its time in the safe zone.
