Get your iPhone XS Max as new, again. SiGN battery is our own, third-party battery with Swedish design and safety that is as good as an original battery. Replace the battery cheaply - yourself. We show below how to do this.

New battery with the same specification

The largest battery in an iPhone, ever. The iPhone XS Max has a battery capacity of 3174mAh - almost twice the capacity iPhones had only a few years ago. Of course, SiGN has the same specifications as an original battery.

How to change the battery?

Changing the mobile power source does not have to be so complicated, rather the opposite. To make a battery change, you will need a battery (of course), battery tape to attach to the cellphone frame, and tools. But then? Watch our instructional video below, and we will go into detail on how to do it.

Safe charging with safe features

Safety first. This is a matter of course for us. Therefore, we have chosen to focus on the product having both overcharging, short-circuiting, and surge protection. And of course, it is CE marked.

Cheap to change yourself

Of course, the most significant advantage of repairing your mobile is the cost. It is possible to save a lot of money on repairing the mobile itself compared to submitting their iPhone for mobile repair. And that a battery loses about 20% in capacity every year is no wonder, so it should not be so strange to change it a little more often either.
