You should generally leave iPhone apps open and only force-close them if they are frozen or misbehaving, as iOS is designed to suspend background apps efficiently, and manually closing them uses more battery and processing power when you reopen them. This common habit of swiping apps away doesn't improve performance or save battery; it actually makes your phone work harder to reload everything from scratch.
You don't need to close apps. iOS handles memory management by itself, you don't need to do anything unless an app is misbehaving, in which case you should just close that app. Closing all your apps makes them take more time and battery to open again than if you just leave them.
For example, streaming videos or music, making calls, and gaming on the go typically cause your battery to drain much more quickly. Other culprits of battery draining include active applications in the background or constantly updating, such as real-time weather apps.
The 20-80 rule for iPhones suggests keeping the battery charge between 20% and 80% to minimize stress on the lithium-ion battery, thereby extending its overall lifespan and health by avoiding the high-stress points of full discharge (0%) and full charge (100%). While not a strict necessity for daily use, this practice reduces battery degradation by avoiding deep discharges and the taxing final 20% of charging, helping maintain battery capacity longer, though modern iPhones have built-in features like Optimized Battery Charging to manage this.
Each open tab uses a portion of your iPhone's memory and processing power, which can result in slower performance and increased battery drain. Additionally, leaving tabs open can pose a privacy risk, as sensitive information might remain accessible to anyone who picks up your device.
Three-finger gestures on iPhone primarily activate accessibility features like VoiceOver (for screen reading and navigation) and Zoom (magnification), allowing scrolling, zooming, and text manipulation (copy/paste/undo) with specific taps and drags, though some text actions work without VoiceOver enabled for quick editing. Common gestures include three-finger double-tap to toggle VoiceOver speech, triple-tap for the screen curtain, and pinching/spreading with three fingers for copy/paste actions, notes this YouTube video.
Should I close apps running in the background? Usually, no. Both Android and iPhone manage memory automatically. Close apps only if they freeze or use too much battery.
You can charge your iPhone every night even if the battery isn't fully depleted. iPhone automatically stops charging when the battery is fully charged, so it's safe to keep your iPhone connected to a charger overnight. Charging resumes automatically if your battery level drops below 95 percent.
No matter what you do, your iPhone® battery has a limited shelf life. 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?
To prolong your iPhone's battery lifespan, it's best to keep the charge between 20-80%. This range minimizes the stress on the battery, reducing wear and tear over time. Avoid letting the battery completely drain or fully charge regularly, as this can accelerate battery degradation.
WhatsApp. The app's constant background activity to sync messages and notifications significantly drains the battery. Its frequent use of media and real-time communication features also contribute to high battery usage, draining your phone's battery.
One of the primary reasons for battery drain on iOS is the usage of resource-intensive apps. Apps that use location services, background refreshing, and other intensive features can significantly impact battery life.
So if you want some advice, don't do it. Today's smartphones are designed to update applications in the background and not require you to close them all the time, especially with iOS. Also, if you close them, besides stressing your device, you also stress those around you.

Optimizing battery health
While it is technically recommended to unplug your phone once the battery reaches 100% to help extend its lifespan, the actual benefit is quite minimal.
It's especially important to avoid exposing your device to ambient temperatures higher than 95° F (35° C), which can permanently damage battery capacity. That is, your battery won't power your device as long on a given charge. Charging the device in high ambient temperatures can damage it further.
Question (xxi): What happens if you leave a device plugged in even after it is charged 100%? Explanation: Leaving a device plugged in after it is fully charged can cause the battery or device to overheat due to continuous charging.
⚠️ Apple is warning users not to sleep next to their iPhones while the device is charging, especially under pillows or blankets. The company says doing so can restrict airflow and cause overheating — posing a fire, burn, or electric shock risk.
Top 10 things that drain your battery
You should only close an app in the quick-launch (App Switcher) screen if it is "misbehaving" - not working right, or if it is using energy (as per Settings/Battery) and you don't need it at the present time. There are several reasons you should not close apps.
Use Task Manager (Windows) or Activity Monitor (Mac) to view running processes and their resource usage. End tasks or quit processes that are unnecessary. 2. Manage startup programs: In Task Manager (Windows) or System Preferences > Users & Groups > Login Items (Mac), disable startup programs you don't need at boot.
