Batteries don’t last forever. As you charge and discharge the battery, it degrades and over time has a shorter battery life than a fully charged battery. Eventually, the battery needs to be replaced.
The battery does not change overnight. Instead, the batteries slowly deteriorate over time. This lack of capacity is a gradual process – it occurs over many charge cycles – and you won’t necessarily notice it until you find that you are used to getting a few extra hours of battery charge from charging. Here are seven signs that you need a new battery.
1. Your battery has outperformed your iPhone
Bad iPhone battery
Why read this? When the battery is taken out of the box, it clearly needs to be replaced! Even if it’s not that swollen, immediate action must be taken to safely dispose of the battery. But be careful: you don’t want to puncture the packaging and release its toxic contents. The first signs of a swollen battery include:
A weak white screen.
- A gap between the screen and the phone body.
- A “spilled” screen (there is no visual pause, but the screen moves slightly when you press the edges of the phone).
Thankfully, don’t panic – here’s exactly what you can do with an inflated battery.
2. Your iPhone shuts down unexpectedly
If iPhone suddenly shuts down while almost half of the battery is left, calibration may be disabled. To recalibrate your iPhone, do the following:
Use iPhone until it shuts down due to low battery power.
Connect your iPhone to a reliable charger and let it charge continuously until it reaches 100%.
When the charging is complete, perform a soft reset by pressing the Sleep / Wake button, the Home button (Sleep / Wake, and the volume up buttons on iPhone X) until you see the Apple logo.
If this does not resolve the battery problem, the battery may be faulty and replaced.
A complex human analogy: a worn-out Li-ion battery is like a heart covered in cholesterol. If you tire a cholesterol-filled heart with exercise, blood flow to your organs may not be enough, and you may lose consciousness. Likewise, an old battery can’t cycle power fast enough to keep up with normal phone use – so it can suddenly shut down.
3. If you have an iPhone 6 or higher – and feel sluggish
If you are using iOS 11.3 or later, you may be a choking victim. You can prove or disprove this by following these steps:
Click the Settings app, select Battery from the list, and then Battery Health. When you see the hype within its maximum performance amplitude:

… then your phone will throttle, and you will benefit from changing the battery.
4. If you have an iPhone 5s or a previous owner – and it has a very long battery life
This means that the simply battery issue you might encounter is reducing usage time. Since all batteries are consumables, the amount of charge they can handle decreases with age. Your battery has run out over the years since you bought your device, and you are probably already used to it. However, if your phone can’t last for two hours without a round of charging and it’s driving you crazy, have it replaced.
5. Your iPhone only works when unplugged
If the battery is completely discharged, the phone will not start working even after plugging in. However, if the phone continues to turn on and function properly when plugged into a power source, then the culprit could be the battery or battery connector.
6. Your iPhone is hot (literally not in Mugato’s way)
Your iPhone battery generates heat when it is charged. The lithium-ion batteries in your smartphone absorb heat and protect it from other parts of the phone. So if you suddenly notice that your phone is too hot to touch it, then it’s time to think about a new battery. But think about your surroundings – if you were taking selfies at the beach in the scorching rays of the sun, it’d probably be the sun. Batteries are sensitive to temperature. Protect them accordingly.
7. Battery reports indicate that it is 40 percent of its original capacity
No matter what your device says about battery health, the rest is up to you. If the battery says it’s up to 40 percent of its original capacity, but you’re still happy with the battery life, you don’t have to pay to have it replaced until it’s running low yet. That isn’t very pleasant.
Battery health reports in your device can help you determine if it is time to replace the battery. However, the decision is ultimately yours. If your battery is good with you, you don’t need to do anything now. It’s best to put that money into future hardware replacements. When the battery is not functioning well, and you are not interested in having your device replaced, it is time to replace it.
