Former Apple employee warns people against making these simple mistakes that are killing your iPhone's battery

If your iPhone’s battery seems to drain faster than ever, a former Apple employee thinks he knows exactly how you’re killing it by accident.

TikTok creator Tyler Morgan, who previously worked for the tech giant, shared a viral video revealing the common habits that could be quietly damaging your iPhone battery over time.

And after hearing his advice, there’s a good chance many iPhone users will suddenly rethink how they charge their devices.

And you wouldn’t think some of his advice would actually make much of a difference.

Former Apple employee’s battery tips

Tyler Morgan, who posts tech TikTok’s under the handle @hitomidocameraroll, explained that one of the biggest mistakes people make is charging their phone to 100 percent all the time and leaving it plugged in overnight.

In the clip, he said, “Do not charge to 100 percent, do not charge it overnight, charge it to 80 percent.”

The former Apple employee explained that constantly keeping a lithium-ion battery fully charged can slowly reduce its long-term health and performance.

Apple has actually built features into the iPhone to help avoid this, including Optimized Battery Charging, which learns your charging habits and delays charging past 80 percent until you need to use your phone.

Morgan also told users: “If you wanna be real cautious put it to 80 percent limit.”

The setting can be found by heading to Settings, then Battery, then Battery Health & Charging on newer iPhones.

Other ways you’re killing your iPhone’s battery

The TikTok creator also warned users against a few other surprisingly common habits.

Morgan suggested turning off unnecessary background app activity, reducing screen brightness when possible, and disabling Bluetooth if it isn’t being used.

He said users should ‘turn off your background activity’ because apps refreshing in the background can quietly drain battery life throughout the day.

Another major issue he highlighted was heat.

The former Apple worker warned against exposing iPhones to high temperatures, including taking them into hot bathrooms while showering or leaving them charging under pillows or blankets.

Apple has previously warned that excessive heat can permanently reduce battery capacity over time, especially when devices are charging.

The video quickly went viral online, with many Apple users sharing their own iPhone’s battery frustrations in the comments.

One person wrote: “My iPhone 11 used to use 30 percent in a day, one update and it’s 80 percent or more used a day.”

Another (clearly an Android user) joked: “Me watching all the iPhone users having to compromise a bunch of phone settings just to have a slightly longer battery life.”
