The blog demonstrates the significance of monitoring smartphone battery health for improved performance and longevity. The poor health results in slow performance, frequent charging, and sudden shutdowns. The guide provides simple steps to check battery health on iPhones and Android devices using built-in settings, diagnostics, or trusted apps. It also shares key signs of a healthy battery and why regular checks help plan timely replacements. With a few smart habits like avoiding overcharging and excessive heat, users can keep their devices running smoothly for years.
Suppose Rohit is a second-year engineering student who takes his online classes on his iPhone 14. Recently, he has been dealing with fast battery drainage, which has caused him a lot of trouble keeping up in his class. He told his best friend, Ridhima, about it; she advised him to check his battery health to be sure what the issue is. When he checked the battery health on his iPhone 14, it showed 69%. This explains a lot, as low battery health can cause shorter usage periods, slower charging, and any unexpected shutdowns. So, he decided to get it replaced in the Apple store at the latest. A healthy battery ensures optimal phone performance with efficient charging, which lasts longer. This saves him the hassle of regular replacements and any sudden interruptions.
If you are also wondering how to check battery health on both iPhones and Android devices, this blog explains the same in detail. The signs of a healthy battery and share actionable tips to maintain battery life. The guide teaches you to monitor and care for your battery, keeping your smartphone running efficiently in the years to come.
Battery health is understood as the overall condition and capacity of a smartphone’s battery compared to when it was newly purchased. As time passes, lithium-ion batteries tend to naturally degrade due to charge cycles, usage patterns, and multiple environmental factors. A healthy battery is prominently known for its original capacity, ensuring consistent performance and a longer usage between charges.
As the battery health declines gradually, the noticeable impacts on smartphones are as follows:
Most devices automatically throttle processing power to prevent any sudden shutdowns when the battery cannot supply enough energy.
The phone may turn off abruptly even when some charge is left. This is possible when the battery cannot maintain a stable voltage.
Over time, the phone would not last long on a full charge. It tends to require multiple charges throughout the day.
There are several benefits associated with regular battery health checks. Some of them are mentioned as follows:
Frequent battery health checkups prevent any sudden battery failure. One can prepare oneself beforehand to decide whether to go for repair or replacement.
A known battery health status helps to maintain smooth operation without any unnecessary slowdowns.
One can avoid overcharging by taking preventive measures. This can further lead to a prolonged lifespan of your battery and your device.
Monitoring your battery health helps you make informed financial decisions regarding your device. If your phone’s battery health has dropped significantly and performance is suffering, a simple battery replacement might not always be the best long-term solution. In some cases, it is smarter to upgrade to a newer model before the device value depreciates further. You can sell old phone online to reputable buyback services, allowing you to recover some investment and put it towards a new smartphone with a fresh, long-lasting battery.
Steps to Check iPhone Battery Health
You can check the iPhone’s battery health by following a simple procedure laid down below.
Apple’s iOS has a unique feature to automatically alert its users when the iPhone battery health is declining significantly. The device showcases that the battery can no longer deliver peak performance. This can be checked the following way: - Settings → Battery → Battery Health & Charging stating “Service Recommended.”
This is not an emergency sign; however, it shows that you should consider visiting an Apple Authorised Service Provider for battery replacement soon. You must keep a check on such alerts to ensure your iPhone continues to function smoothly and efficiently.
Battery health in Androids can be checked in multiple ways, depending on the manufacturer and its version. Different brands like Samsung, OnePlus, Xiaomi, and Google Pixel often include their respective diagnostic tools or menus to check battery health.
A step-by-step guide is given to check battery health on most Android devices:
This section showcases how the battery is performing. It includes screen-on time, power-hungry apps and the remaining charge.
Most brands provide quick tests to check the battery health status. These can be understood as follows:
If your phone doesn’t show battery health by default, apps like AccuBattery, Battery Guru, or Device Info HW can estimate battery capacity, charging speed, and overall wear.
