How to optimize iPhone’s battery life? iPhones have some of the longest-lasting batteries in the industry, thanks to software and hardware optimizations. But if your iPhone burns through its battery capacity in just an hour or two, there could be a few reasons why.
Modern electronics like iPhones have rechargeable lithium-ion batteries that lose capacity overtime. In fact, if you recharge your phone every day, it’s battery may only last a couple years before losing its ability to hold a charge for more than a few hours. Forcing you to carry around a charging cable to prevent your iPhone from randomly shutting down. You can fix this by visiting an Apple Store and paying fifty to seventy dollars for a battery replacement.
iPhone’s signal strength
If you only have one or two lines showing up in the status bar, that means the connection your iPhone has to its cellular network is weak. This forces the phone to amplify the signal and maintain a usable connection. Which takes significantly more power compared to having three or four network bars. Now a cell signal can become weak when you’re far away from a cell tower, but it can also happen when there’s high congestion. So, when you’re at a sports game, concert, or in a high-density area, everyone’s phones are fighting over a limited amount of spectrum. Which can result in a weak signal that puts extra strain on your iPhone’s battery. But there’s a third problem that can show up at the worst possible time, heat.
If you’re outside, with a weak signal, in hot weather, you may notice your battery level dropping in real time. That’s because your phone is pushing itself to amplify its weak cell signal, which requires more processing power, which generates extra heat. If this happens in hot weather or direct sunlight, things can become catastrophic rather quickly. You may notice the iPhone’s display dim with no way to turn it back up. That’s because the phone’s trying to cool itself down. And heat is one of the worst things for batteries. Not only will it quickly drain your battery, but it’ll degrade its overall lifespan. Forcing you to buy a replacement sooner than you might expect.
So, to optimize your iPhone’s battery life, make sure it isn’t too old, try to maintain a strong cell signal, and avoid overheating.
