iPhone 6s: empty battery after ~8-9hours idle time

Hi, thank you for your reply.

My old battery was almost 2 years old and I think it’s performance was even a bit worse than this new battery.

I can not place the old battery back as It was bent in the process of removing it (the adhesive was quite strong).

I will contact ifixit support.

regards

Ivo

Be careful with bending the battery. Those things will literally catch fire if you short the positive and negative. When you bend it,inner layers can short together. It will smoke and burn. You should keep a fire extinguisher nearby Incase.

Like Minho said,the battery can be the problem. If it’s a component issue,the “gas gauge filter” sometimes gets knocked off when disconnecting the battery. It’s usually right next to the batter port. If you see crooked flat yucky solder pads,it’s an indication it lost a component.

Hopefully it’s simply a bad battery though.

@skyethespy just a quick note. On the iPhone 6S series, there is no gas gauge filter. There is a 100 Ohm resistor on that line but it is on the reverse side of the logic board and therefore isn't susceptible to being accidentally knocked off while disconnecting the battery.

Ok. Thanks for letting me know. I am still learning. Sorry about that.

@skyethespy no worries, learning is good.
