GPS chipset? BCM 47775?

So there is no heat sink or heat pipe here as we see these days with those Samsung flagships!

I think i could replace my OPO's battery with OP2, what suggestions? Are the dimensions same? I'd like to add those 200mAh.

Copper sheet sticker acts as heat sink but there is only a small piece of it. In htc and Samsung phones it is wisely used.

I think the copper sheets provide good heat transmission and it is found used in htc phones quite widely but i am worried about OnePlus phones, thermal management is poor though.
