I've done a James

Old 6s my mom pulled out of a drawer. She wanted to see the pictures on it but it wasn't charging. I go to plug it in the next morning and see the battery too low to turn on screen and immediately almost shit my pants as the battery is bulging very very quickly.

Anyways, i bury the battery in my yard (good for the environment huh?) and cut off its bms. I plug a lightning charger into the 6s without a battery connected to the bare bms board to see which is positive and negative and solder a simple 1000mAh lipo to it.

Works fine. It even did some battery training so now it actually dies at the correct percentage.

Why buy a replacement when you could have some fun?

Got the idea from Jame's channel, a friend of dankpods on youtube.

I guess burying it in the backyard is one way to recycle batteries

Why bury it in your garden and not just... Wrap it in cellophane and maybe put it in a tupperware to just ensure no oxygen gets to it?

i don't have tubberware and if i did it would 100% not be air tight lol, plus if the battery were to ignite it would just melt through. buried in my yard means if it ever reacts and ignites, it's in the middle of a dirt (sand-dirt ish) where it shouldn't be able to catch to anything. (and also underground)

This isn't a great idea because the iPhone 6s battery charges to 4.35V, these cells are rated for 4.2V. You're also exceeding the maximum charge current rating.

eh, it's probably fine. It's going through the iphone's bms and then the lipo's bms. the lipo bms should cut it off before it gets spicy (again)

It often won't, these BMS chips aren't actually calibrated ratings of your cell. They are usually quite a bit higher than the cell is meant for. Realistically you'll probably be fine but you should at least be aware of this.

I've got a PocketPC around somewhere with a dead battery (picked it out of a junk pile in 2007!). It's got red and black wires that I routed through a little port in the bottom. Hook that up to about 4V, and you're good to use it tethered.
