Your iPhone battery typically lasts about two years or more. How can you tell when it’s time to replace it? This article highlights key indicators for replacing your iPhone battery.

Sign 1: Visible Swelling
A clear indication that your iPhone battery requires replacement is visible swelling. This can occur due to overcharging, physical damage, or natural aging.
Swelling may cause the iPhone casing to bulge, especially around the back panel. Pressing on the iPhone’s surface may reveal an uneven or slightly squishy feel, signaling a swollen battery underneath. In severe cases, the pressure from the swollen battery can cause the screen to separate from the iPhone’s frame.
If you observe swelling, cease using your iPhone immediately. Visit a local Apple Store or an authorized service provider for replacement or proper battery recycling. Ignoring this issue may result in additional damage and compromise the device’s structural integrity.
Warning: Do not attempt to repair a swollen battery yourself; the internal components are hazardous and require specialized handling.
Sign 2: Drastic Battery Life Decline
Your iPhone operates on a lithium-ion (Li-ion) battery known for its extended lifespan and quick charging. However, even Li-ion batteries have a finite life. With continuous use over time, your iPhone’s battery loses its efficiency in storing and releasing energy, leading to a notable decline in battery life.
If your once-all-day-lasting battery now barely lasts a few hours or requires multiple daily charges, it signals a significant deterioration. You may notice a rapid drop in the battery percentage even during basic tasks, or your iPhone might only function when connected to power.
Experiencing any of these issues indicates a severe decline in battery lifespan. It’s advisable to contemplate battery replacement in such cases.
Sign 3: Battery Health Below 80%
Easily determine if your battery needs replacement by checking its health. According to Apple, a battery health of over 80% indicates a healthy battery.
To assess this, go to Settings > Battery > Battery Health & Charging on your iPhone.
The “Maximum Capacity” value reflects the remaining capacity compared to the original. If it’s below 80%, replacing the battery is recommended for improved performance and a longer device lifespan. Additionally, a crucial battery message at the screen’s top will prompt you to visit an Apple Authorized Service Provider for battery replacement.
Sign 4: Frequent iPhone Overheating
A deteriorating battery is a common cause of iPhone overheating. While internal components naturally produce heat during regular use, a properly functioning battery dissipates this heat through the device’s casing. However, if your iPhone consistently overheats without apparent reasons—such as sun exposure or demanding apps—it signals a problematic battery.
As the battery degrades, it generates more heat, leading to potential damage and reduced lifespan. If your iPhone frequently overheats, even during light usage, it strongly suggests the need for battery replacement.
Sign 5: Unexpected Shutdowns and Performance Management
Sudden iPhone shutdowns or performance management alerts are red flags for a struggling battery that requires replacement.
As iPhone batteries naturally degrade, they may fail to meet the device’s power demands, resulting in abrupt shutdowns—especially under heavy load. If you encounter these issues, check for performance management notifications by going to Settings > Battery > Battery Health & Charging. Look for a message under “Peak Performance Capability,” indicating an unexpected shutdown and the application of performance management.
In such cases, your iPhone’s battery needs attention and likely replacement.
Sign 6: Lagging Apps and Slow Performance
If your iPhone apps and overall system performance are frustratingly slow, it might be due to an aging battery.
Performance issues, like delays and unresponsiveness during basic tasks, are common signs of degraded batteries. While other factors can contribute to slowdowns, a deteriorating battery is often the primary culprit. If you find yourself dealing with lagging apps, sluggish system performance, and delays in everyday tasks, it’s advisable to explore the option of replacing your iPhone’s battery.
Summary
Recognizing signs of a deteriorating iPhone battery is crucial for maintaining optimal device performance. Visible swelling, a significant decline in battery life, a health level below 80%, frequent overheating, unexpected shutdowns, performance management alerts, and lagging apps are indicators that it may be time to replace the battery.
Disclaimer: It’s essential to note that attempting to repair a swollen battery or any internal components yourself can be hazardous. For battery replacement or related issues, it is recommended to seek assistance from a local Apple Store or an Apple Authorized Service Provider. Ignoring these signs may lead to further damage and compromise the overall functionality and safety of your device. Always prioritize safety and professional assistance for any battery-related concerns.
