How to Check Your Phone’s Battery Health

Our smartphones have become an essential part of our daily lives. We rely on them for communication, work, entertainment and so much more. However, the heart of any smartphone is its battery and over time battery health can deteriorate affecting your device’s performance and longevity. OzPhone Repairs will guide you through various methods to check your phone’s battery health to ensure optimal performance and know when it’s time for a mobile battery replacement.

Why check your phone’s battery health?

Firstly, it’s crucial to understand why monitoring your phone’s battery health is important. As batteries age they lose their capacity to hold a charge which can lead to shorter battery life, frequent charging and in some cases unexpected shutdowns. By regularly checking your battery health you can anticipate when you might need a replacement, adjust your usage habits to prolong battery life and ensure your phone remains reliable throughout the day.

Some ways to check phone battery health

For Android phones:

Android phones offer several ways to check battery health:

  1. Built-in Settings:
    • Go to Settings > Battery > Battery Usage
    • Some phones may have a “Battery health” option directly in the Battery settings

For iPhones:

Apple has made it relatively simple to check battery health on iPhones:

  1. Settings Method:
    • Go to Settings > Battery > Battery Health & Charging
    • Here you’ll see “Maximum Capacity” which indicates your battery’s health

Understanding battery wear level

The term “wear level” refers to how much your battery has degraded from its original capacity. A new battery starts at 0% wear and increases over time. For example, if your battery health shows 85% it means your battery has a 15% wear level.

 

Most manufacturers consider a battery to be at the end of its useful life when it reaches 80% of its original capacity. At this point you might notice significantly shorter battery life, need for more frequent charging and unexpected shutdowns, especially with several apps open.

How to know if your battery needs replacing

There are several signs that indicate your battery might be deteriorating:

 

  • Rapid battery drain – If your phone loses charge quickly even with minimal use
  • Overheating – If your phone gets unusually hot during charging or normal use
  • Bulging or swelling – A visible change in your phone’s shape could indicate a swollen battery (this is dangerous and requires immediate attention)
  • Random shutdowns – If your phone turns off unexpectedly even with charge remaining
  • Slow charging – If your phone takes much longer to charge than it used to

Battery health testers

While built-in tools and apps are useful; dedicated battery health testers can provide more accurate results. These devices connect to your phone and measure actual battery capacity, voltage and other parameters. They’re particularly useful for technicians or those who want precise measurements.

How to test battery capacity

To get a rough idea of your battery’s capacity, below are some tips to try:

 

  • Charge your phone to 100%
  • Use it normally until it reaches about 20%
  • Note the screen-on time and overall time since full charge
  • Compare this to when your phone was new or to manufacturer specifications

 

Remember factors like screen brightness, app usage and network connectivity can affect these results.

Tips to maintain battery health

  • Avoid extreme temperatures as both heat and cold can damage batteries
  • Use original or certified chargers. Cheap uncertified chargers can harm your battery
  • Keep your battery charge between 20% and 80% when possible
  • Update your software as manufacturers often include battery optimisations in updates
  • Reduce background app refresh. This can significantly reduce battery drain
