A healthy battery is essential for getting the best performance and longest lifespan from your iPhone or iPad. However, it's natural that your battery will degrade through usage over time.
In this guide, we'll show you how to check your device's battery health with TouchCopy, understand what the key details mean, and learn practical tips to make your battery last longer.
Before you get started, download and install TouchCopy free on your computer.
These labels correspond to the charging indicators in the TouchCopy screenshot above.
Note: Keep an eye on the Maximum Capacity figure - it's the best way to track how your battery is ageing. A small drop isn't a cause for concern, but if the number falls noticeably, you may start to see reduced battery life.
These indicators in TouchCopy show whether your device is connected to power, actively charging, or has already reached a full charge.
Note: Your device may be connected to power but not charging, even if the battery is not fully charged. This is normal if you use features such as "Charge Limiting" or "Optimized Battery Charging", which intentionally pause charging to help protect your battery's long-term health.
You can access these features on your iPhone or iPad by going to Settings > Battery > Charging.
TouchCopy will show you the total number of full battery charge cycles used. One cycle equals 100% of battery usage, even if it happens across several partial charges. For example, if you use 60% of your battery, charge it to full, and then use another 40%, this is one complete cycle (60+40=100).
A higher cycle count means the battery has experienced more wear and will naturally hold less charge over time.
This is an estimate, shown in TouchCopy, of how long your device's battery will last before reaching 0%, based on your usual usage and power consumption.
TouchCopy displays the current temperature of your device's battery. Keeping your battery within a normal temperature range helps maintain its health and performance. If your device is too hot or cold, it may charge more slowly or not charge at all until it reaches a normal temperature.
The recommended temperature range for iPhone and iPad usage is 0º and 35ºC (32º to 95ºF).
iOS and iPadOS updates often include power efficiency improvements and battery-related optimizations.
TouchCopy will let you know when your connected device has an update available.
You can update your device by going to Settings > General > Software Update.
Lithium-ion batteries (used in iPhones and iPads) lose capacity with each charge cycle. So, it stands to reason that the less you use your battery, the fewer cycles you'll rack up, and therefore the longer your battery will last.
Save battery power where you can by:
Enabling Low Power Mode will reduce screen brightness, disable many power-hungry features and more with a single tap. Your iPhone or iPad will ask if you want to turn on Low Power Mode when your battery gets low.
Using TouchCopy to regularly check cycle count, capacity, temperature etc will help you spot when the battery becomes significantly degraded or damaged. This information can help you decide if and when to consider taking the device for a service, where an Apple Authorized Service Provider can replace the battery.
Monitoring your iPhone or iPad's battery health is one of the best ways to maintain performance and improve its longevity. With TouchCopy, you can quickly check essential details like capacity, cycle count, temperature, and charging behavior, giving you a clear picture of your battery's condition at any point in time.
By following the tips in this guide, you can reduce unnecessary wear, charge less often, and keep your device running smoothly for longer — saving you both time and money in the long run.
