Can we use a different battery in the iNew v3?

Are you really this desperate that you would endanger your and other prople' health because you are unhappy with the battery life of your phones?

If it doe not fit use sandpaper seems to be extremely dangerous to me especially with we all know how it may end up fire catching batteries.

I pulled the plug and sell mine because of the not optimal battery, despite the fact that I did buy two non fitting ThL W8 batteries. Messing with those to mane them fit? No way. But of course it is up to you.

There is no way to catch fire by using a sandpaper on the battery.
More dangerous is to use a soldering iron. The batteries can stand no more than a 1'- 2' of the soldering iron.
Anything more can destroy the battery or at worst case scenario the chemicals will boiled and the battery will explode.
I have a personal experience with an explosion of cell battery when I touch it with the soldering iron. I am not saying that will happened every time but it is good to have it on mind when you are using soldering iron on batteries.
If you don't know what are you doing, then don't do it!
