Battery Life Isn’t as Good as It Was
It doesn’t matter if your iPhone is still a performance beast if you can’t make its battery last more than a few hours.
Sure, the iPhone has never had the best battery life on the market, but as your device gets older, the battery will also start to reduce its capacity.
There are a few things you can do to slow down the aging process of a battery, but if your battery is too old, the damage will already have been done, and you should consider upgrading your iPhone — or at least changing the battery. However, even though a battery replacement is reasonably affordable compared to the price of a new phone, you have to ask yourself if it’s really worth pouring money into a much older model.
