How to Turn Off Optimized Charging on Your Phone

Your phone can be smart about how it charges.

The way phones are charged is changing: it’s no longer that plugging your phone into an outlet will charge it to 100 percent as quickly as possible, and that’s because the latest phones have a choice of smart ones Charging functions have their batteries in smarter ways.

This is done to improve the overall lifespan of phone batteries and ensure they remain reliable for longer. You may have had an older phone that was declining battery life very quickly, reducing both battery capacity and its ability to hold a charge. Nowadays that’s less likely.

It’s important to know your phone’s optimized charging process when you plug it in, and how to turn it off when you need it – for those times when you need to get the battery level to the max as quickly as possible. This is how charging works on iPhones and Android devices released in recent years.

Since iOS 13, iPhones have had access to a feature called Optimized Battery Charging, which apple says “learns from your daily charging habits to extend the life of your battery” – in other words, your phone remembers how it’s used throughout the day, so it knows when it needs to have as much battery charge as possible and when you do there are most likely it is connected to a power source.

The feature is enabled by default when an iPhone is set up, and you’ll see a notification on the lock screen when the tweak is implemented: The message should say something along the lines of when your phone will finish charging (It might well, for example be whenever your alarm clock is set in the morning).

Go to Settings in iOS and tap battery and then Battery status and charging to show the current capacity of your battery: This means how much capacity is left compared to when the handset was new from the factory. This is the value that optimized loading aims to keep as high as possible for as long as possible. It is simply the nature of rechargeable lithium-ion batteries that their capacity decreases over time.

On the same screen you can toggle them Optimized battery charge feature off, which reverts charging behavior to the traditional approach of juicing the battery as quickly as possible when the phone is plugged into a power source. If you turn off optimized charging, you’ll be asked if you want to turn it off until the next day or until you decide to turn it back on.

It’s worth noting that the optimized charging feature in iOS uses the location information reported by the phone, so location services must be on for everything to work. If your iPhone is in an unfamiliar location – for example, you’re traveling – the optimized charging function will not be used because iOS cannot easily predict your charging habits.

What you actually get with Android phones, as with many other features, depends on the make and model of your handset: Optimized charging isn’t a feature that’s available on every Android device, so you might have something in for it browse settings or do a quick web search for details about your handset.

When it comes to the stock Android software running on the Google Pixel phones, you have access to something called adaptive charging. Google says that the feature “will help preserve battery life over the long term” and that it works similarly to optimized charging on the iPhone. If Android thinks you’re going to charge your phone for a while based on previous charging patterns, it slows down the charging process.

There’s a specific scenario where adaptive charging might come into play: if you have a morning alarm set between 3am and 10am and you charge your phone between 9pm and 4am, adaptive charging might apply (Google doesn’t say why it may or may not). When the feature turns on, a message will appear on the always-on display to let you know when charging is complete.

The thought is that you won’t be using your phone while you’re sound asleep, so it may take some time to charge – you will Wake up in the morning with a fully charged phone according to your alarm clock settings. If you typically charge your phone for several hours at other times (perhaps in the office), you might see adaptive charging come into play here too.

If you still want your phone to charge as quickly as possible – maybe you think you might get an unexpected call in the middle of the night, for example – you can turn off adaptive charging by going to Settings in Android and then selecting battery, Adaptive Preferencesand Adaptive loading.
