How can I maximize my iPhone battery life? ›

There are two simple ways you can preserve battery life — no matter how you use your device: adjust your screen brightness and use Wi‑Fi. Dim the screen or turn on Auto-Brightness to extend battery life. To dim, open Control Center and drag the Brightness slider to the bottom.

The two things that cause the most battery drain in your iPhone are its screen and cellular service. Obviously, you know when you're actively using your phone, but your iPhone is often performing tasks in the background and even lighting up your screen without you noticing.

There's only one thing that you can do to keep your iPhone's battery health at 100%. Stop using your iPhone. Yup, the only way you're going to keep your iPhone's battery at 100% is to stop using it and charging it.

Shomes recommends charging your iPhone as it needs it. If you go to sleep and it has a 40 or 50 percent charge, leave it. Then charge it some time during the next day when it gets into the red. That way, the battery won't be stressed, and its health will last way longer than it will when overnight charging.

Charging your phone overnight occasionally probably won't make a noticeable difference in the battery life for years to come, but if you do it every night consistently, you will probably notice your battery performance degrading over time.

How often you charge will affect the battery life, for better or worse. In short, the more often you top up your battery, the better. To REALLY minimize battery degradation, top up for every 10% drop in battery level. And keep your battery level as close to the middle (50%) as possible.

When should I replace my iPhone battery? Typically, when your iPhone holds less than 80% of its maximum capacity, it's time to upgrade the battery. You can check your battery's health by going to Settings then Battery Health.

Do apps use battery when not in use? ›

While background apps may not use your phone's resources on their own, Android phones and iPhones will refresh background apps periodically by default. This uses your phone's battery and your data.

Therefore, we recommend the following: Do not fully charge or fully discharge your device's battery — charge it to around 50%. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge.

For most users, this represents approximately two years of use, which is why most people believe that the lifespan of a phone is two years. However when it comes to iPhones, you can expect between three to five years (maybe more) with proper care.

As it ages, the battery slows—so a full charge won't last as long. Most batteries are good for at least 2 to 3 years, often longer, but how do you know when to replace your iPhone battery? At Asurion, we help millions of people maximize their tech.

An Apple Authorized Service Provider can replace the battery free of charge to restore full performance and capacity. Learn more about getting service for your battery.

That way, the battery won't be stressed, and its health will last way longer than it will when overnight charging.

Most Smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity.

Charging overnight is not a danger to your battery in and of itself. However, temperature is a real concern. One of the most damaging things your battery can experience is extreme heat or extreme cold.

Batteries decay from the moment you start using your new phone. This means they gradually lose their ability to hold a charge. By charging your phone overnight, you're increasing the amount of time it spends with the charger. As a result, it degrades the capacity much sooner.

Why should we not use phone while charging? ›

However, using your phone while charging will cause it to charge much more slowly. That's because you're drawing power from the battery at the same time that you are trying to charge it. In fact, using your phone while it's charging is one of the main culprits behind slow charging speeds.

Yes, you can use your smartphone while charging. There is no danger in using your phone while it's charging. When you use your phone while charging, the battery is charging at a slower rate than normal to allow enough power for the ongoing usage.

Keep your cell phone at least 3 feet away from your bed to limit radio frequency exposure. Turn your cell phone off before you go to bed (if you don't rely on your phone's alarm clock) Turn your phone on Airplane Mode.

Charging your iPhone overnight reduces battery life

And as you know, leaving your phone to charge overnight will charge up to 100 percent. This means, that if you charge every day overnight, your battery performance will begin to diminish within a few years.

Android phone manufacturers, including Samsung, say the same. “Do not leave your phone connected to the charger for long periods of time or overnight." Huawei says, "Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life."

Is it bad to charge your phone multiple times a day? No. Lithium-ion batteries like to be charged in short spurts, so plugging in for five-percent here and 10-percent there is not only fine, but advisable.

If your phone's battery is draining faster than usual, it either means you're using a lot of energy or your phone is not using energy efficiently. This could mean you're overworking your phone by running too many applications, or something is physically wrong with the phone battery itself.

On both Apple and Android devices, go to Settings > Battery to see a list of which apps are hogging power on your device.

Apple considers any iPhone with a battery capacity of 80% or above to be in optimal condition. In fact, Apple feels so strongly about battery health that its 1-year warranty covers any battery at 80% capacity or more. It's not unusual to see iPhones that, after one year, still have a battery capacity of 95% or above.

Starting March 1, Apple (AAPL) will charge $89 for battery replacements for iPhone X through iPhone 13 models, a $20 increase from the current price of a new battery. Battery replacements for other models, such as the iPhone SE and iPhone 8, will jump from $49 to $69.

Does changing iPhone battery improve performance? ›

Changing an iPhone battery does nothing for the iPhone's performance. Your phone needs electricity to function. The battery provides that. Except for the obvious case of running out of power, your iPhone will not perform faster with a new battery — it will just perform longer before it runs out of power.

Apple recommends that you periodically drain your iPhone or iPad's battery totally and then charge it up until it's completely full. That's down to 0, and up to 100 percent. You should do this at least once a month. This process, called calibration, helps your device estimate its battery life more accurately.

Is it okay to charge iPhone 4 times a day? Charge it as often as you like whenever you like. You won't damage the battery.

A battery's lifespan is related to its “chemical age,” which is more than just the passage of time. It includes different factors, such as the number of charge cycles and how it was cared for. Follow these tips to maximize battery performance and help extend battery lifespan.

What is the 40 80 rule? ›

The 40-80 rule is a way to maximize the lifespan of your battery by limiting the damage ; specifically it refers to not discharging below 40% and not above 80%. Charging above 80% becomes increasingly cause damage to the battery life cycle. Normally the life cycle of lithium ion battery is 300 to 500 charge cycle.
