Ah, thanks for the reminder d_t_a, my wife has been using this MI quite a lot so it’s probably got a lowered capacity. It reads sort of strange, at one place it says 6250mAh, another it states 9510/10000 as min/typ. This one has Texas Instruments components and is supposed to have very high efficiency, well over the 90% mark, but it’s 3 18650’s may be getting worn.
The other, the USB C one, is 10,000mAh with Li-Polymer pack, it’s about the same size as my wife’s phone. Also with TI components and high efficiency. (this is the one the meter is hooked up to, in the picture and still charging)
As it works out, the i8 has a pretty good break-down of what is using the battery and to what percentage, so it’s pretty easy to configure my new phone to conserve power. Except I talk to a friend from BLF using speakerphone and we build lights while talking for hours so my phone gets run down easily when we are doing that. lol 50% of my battery usage in the past week has been on speakerphone.
