iPhone battery problems
You’re probably here because you suspect that your iPhone is showing some odd behaviors - sudden shutdowns, increased heat or you simply find yourself charging your device every so often. These are just a few of the common iPhone battery problems that we all have experienced. And if you’re the type that would rather save money on repairing than buying brand new, then read on.
iPhone batteries are lithium ion-based. More commonly known as Li-Ion, these batteries are known to be lightweight, have no memory and do not need to be fully discharged to keep healthy. Unfortunately, this does not last forever. You’ll notice minor performance changes after about 12 months. 6 - 12 months later, i.e. when the battery is 1.5-2 years old, the battery may not perform well at all and it can get frustrating. Big brand companies know this which is why they offer only up to 6-months of battery warranty. It’s also an incentive to buy a new phone rather than repairing. Such a waste.
In this article, you’ll find some common iPhone battery problems to help you decide if it’s time to replace the battery.
- iPhone is not charging - While we can blame this issue to the charger or the charging port, oftentimes it is just the battery failing. If the device does not charge despite using several chargers, then chances are, the battery is faulty. In this case, it’s due for a battery replacement.
If the battery has been replaced and it still does not charge, then it is highly likely that the problem is caused by something else. The charging port is the next most likely culprit.
Battery drains in large chunks - This can sometimes be caused by a software problem. Check first if you see any patterns; does the phone drain particularly quickly when certain apps are used? If the problem is due to software, a hard reset of the phone or updating it can the the issue.
If every suspicion has been ruled out, then it’s likely that the battery is faulty and it’s time to replace it.
- Battery gets too hot - A classic symptom. Batteries normally gets warm when charging or when using demanding apps such as Facetime (video) or GPS, but if it gets surprisingly hot, it is possible that the battery is faulty. When this happens, stop charging and let your device cool down and rest. If this happens consistently, the device should be inspected and ultimately, the battery should be replaced.
- iPhone shuts down randomly - Now this could be another software issue but in most cases, it’s just the battery acting up. The phone automatically shuts off because the battery is unable to provide power. If the battery has deteriorated significantly, the phone may shut down already when the battery reaches 10-20% charge. The worse condition the battery is in, the more frequent the shut downs will become.
iPhone shuts off and does not power on - I’ve been there. Leaving my iPhone charged overnight only to wake up terrified that it won’t even power up. Although this issue could be caused by a bad screen or a software glitch, in most cases, it’s just a dead battery. If this happens and the phone doesn’t react when pressing/holding the “Power” button, you may need to do a “hard reset” on your phone. A hard reset is similar to pulling the power cord from a desktop computer. It forces the phone to reboot.
How to do a hard reset:
- iPhone 3G to iPhone 6S Plus: Press and hold the power button and home button simultaneously for 15 seconds (or until the Apple logo on the screen appears).
- iPhone 7 & 7 Plus: Press and hold the power button and volume down simultaneously for 15 seconds (or until the Apple logo on the screen appears)
- iPhone 8 to XS Max: Press and release volume up, press and release volume down, then press and the power button for 15 seconds (or until the Apple logo on the screen appears).
- iPhone battery is bulging, swelling or expanding - An issue that can occur with any Li-Ion based battery. This is caused by an imbalance of chemicals within the cells that heat builds up and expands the battery. When the battery has expanded enough, it pushes the phone screen up. It’s definitely scary as it looks like your phone is ruined but as soon as the battery has been replaced, the screen will just slide back into position. Li-Ion batteries have safety features built within for issues like swelling and expanding. When the battery has expanded, it means the safety feature has worked. Unless the battery (swollen or not) is punctured or physically damaged, it will not explode.
We’ve written a separate article just for this topic. Here’s our iPhone battery bulging article.
Apple’s official reasoning was that this precaution will prevent the phone from randomly shutting off due to a worn out battery. The public, however, was furious that their close-to $1000-device was working at reduced speed.
“Why pay a premium if you don’t get premium performance”, was repeated all over the internet. Luckily, our ScandiTech batteries for iPhones (LINK) will bring your phone back to full speed after a battery replacement.
There are several reasons behind iPhone battery problems but usually, these are exposure of the device in extreme temperatures, improper use and using bad quality accessories like unofficial chargers, or, the most common reason, the battery is simply degrading.
Fortunately, ScandiTech understands all this as well as the cost of getting a brand new phone. Why buy when you can just replace the battery and kickstart your current phone. You save time, money, and even reduce tech waste.
