iPhone users may experience a battery-draining issue, which can have a variety of causes. When a battery is charged to 100%, discharged below 20%, or overheated, it can damage the battery’s health, resulting in a faster-than-normal battery drain.

Additionally, using the phone while charging and not enabling Low Power Mode can reduce battery life.

My iPhone Battery Draining

To conserve battery power and extend the life of the battery, it is important to understand the factors that affect battery health and how to manage it properly.

This article will discuss:

  • What kills battery
  • Charging habits
  • How to manage battery health.

What’s killing my iPhone’s battery?

Charging to 100%, discharging below 20%, overheating, using the phone while charging, and not turning on Low Power Mode are all factors that can negatively affect the health of an iPhone battery and cause it to drain faster.

If the battery is charged to 100%, it reduces battery duration and capacity, while discharging below 20% before charging can reduce capacity and lead to complete discharge.

Overheating the phone can damage the battery permanently, as can using the phone while charging.

Low Power Mode helps extend battery life and should always be turned on.

All of these can cause the iPhone battery to drain faster.

Charging Habits

Prolonged charging practices can decrease the battery duration and capacity of an iPhone. Charging above 80% has been known to reduce battery life. Apple recommends not charging the device overnight.

Charging to 100% can lead to a reduction in battery duration as well as a decrease in battery capacity. It is also important to charge the device before it reaches 20% as discharging below this threshold can affect the battery’s capacity.

Additionally, it is important to note that overheating the device can cause permanent damage to the battery. Finally, using the device while it is being charged can put stress on the battery.

Manage Battery Health

Manage Battery Health

To effectively manage battery health, it is important to consider charging habits and reduce the usage of power-greedy applications. Managing battery health can be done in several ways:

  • Charging Habits:
  • Avoid charging to 100%
  • Don’t discharge below 20% before charging
  • Don’t leave Iphone on charge overnight
  • Reduce Usage of Power-Greedy Apps:
  • Check battery usage
  • Enable Low Power Mode
  • Turn off Raise to Wake
  • Delete or update power-draining apps

Frequently Asked Questions [FAQs]

What factors can reduce the life of my iPhone battery?

Factors that can reduce the life of an iPhone battery include charging to 100%, discharging below 20% before charging, overheating, using the phone while charging, and not turning on Low Power Mode.

How often should I replace my iPhone battery?

iPhone batteries should be replaced when their maximum capacity significantly decreases or when the service option appears. It is important to regularly check the battery health in Settings to determine if a replacement is necessary.

Should I keep my iPhone plugged in while I use it?

Using an iPhone while charging is not recommended, as it stresses the battery and can reduce battery health. It is best to charge the iPhone to a decent percentage before use and unplug it from the charging port during use. Low Power Mode should be turned on to conserve battery power.

What should I do if my iPhone battery is overheating?

If an iPhone is overheating, one should reduce its usage and avoid charging it with the back cover on. It is important to keep the core temperature below 35°C to prevent permanent damage to the battery. Utilize Low Power Mode to conserve battery power and unplug the device when not in use.

Is it better to completely discharge my iPhone battery before recharging?

It is not recommended to completely discharge a lithium-ion battery before recharging, as it affects battery capacity and damages battery health. Discharging below 20% is recommended to prevent full charging next time and to maintain battery health.
