How to know when it is time to replace your iPhone battery?

There are several signs that indicate it may be time to replace your iPhone battery. These signs include: 

• Decreased Battery Life: If you find that your iPhone’s battery life is significantly shorter than it used to be, even after minimal usage, it could be a sign that the battery is deteriorating and needs replacement.
• Slow Performance: An aging battery can lead to slower performance on your iPhone. If you notice that your device is taking longer to open apps, respond to commands, or experiences lags, it might be due to a degraded battery.
• Overheating: A worn-out battery can cause your iPhone to overheat, especially during heavy usage or while charging. If you notice excessive heat coming from your device, it is a warning sign that the battery may need attention.
• Unexpected Shutdowns: If your iPhone shuts down unexpectedly, particularly when the battery indicator shows a remaining charge, it could be an indication of a failing battery.
• Swollen Battery: In some cases, an aging iPhone battery may swell, causing the back of the phone to bulge. If you notice any physical changes in the shape of your iPhone, stop using it immediately and seek professional assistance.
• Battery Health Indicator: You can check the health of your iPhone’s battery by going to Settings > Battery > Battery Health. If the Maximum Capacity is significantly below 100%, it suggests that the battery is wearing out.
• Age of the Device: As a rule of thumb, if your iPhone is more than two years old and you have been experiencing any of the above symptoms, it might be time to consider replacing the battery.
