It’s no surprise that lithium-ion batteries powering nearly all our devices tend to wear down. As your phone ages the quality of its battery declines, it begins to die rather rapidly, and it usually results in sudden shutdowns and poor functionality of the device. In this case, the battery surely needs to be replaced by a new one.

So how can it be done? In fact, Apple offers to replace the iPhone 6s battery for quite an agreeable price, but the problem is, it may take too long as there’s unlikely to be batteries for this model in stock, and you’ll have to wait for months. The other variant is to find some local repair shop and have a specialist do all the work provided they have a battery for your phone.

Both variants are possible yet not easily realizable.

So is it that necessary to get someone else to do it? The truth is the battery replacement can really be done on your own. It’s not so difficult as it may seem though pretty harder compared with the same procedure when it comes to products of the different brand. The work will take only about half an hour.

The definite advantage is that you won’t have to wait for Apple or search for some repair service. Besides, it’ll be cheaper than either of the mentioned options, especially the latter one.

Before setting about to replacement, let’s take a closer look at the battery under consideration to be fully aware of what we’re dealing with.

Characteristics of the iPhone 6s battery

The battery capacity is 1715 mAh, which means that it was reduced by 95 mAh as compared with iPhone 6. However, it’s said that iPhone 6s and iPhone 6 have the same battery time.

Undoubtedly, preserving the same autonomy with employing smaller capacity has been managed with the help of more modern electronic components, particularly by means of the A9 chip with motion coprocessor M9 instead of solving the A8 with M8 motion coprocessor.

Time for replacement of the iPhone 6s battery

There are a few causes of battery breakdown. But what is the indicator of the fact that the problem has been caused by the battery itself? If there’s no charge, if the work time is reduced to a few hours a day, if a smartphone doesn’t turn on, then the battery needs to be replaced.
