With their impending trip to visit the factory, I would really be interested in them asking a few questions.
Please ask them why they did they troll everyone with the one plus one smartphone where they made the battery non user replaceable?
When the back cover is removed, the battery is right there. Why be jerks and have it connected using a flat flex cable that requires more disassembly of the phone to get to. Why not use spring contacts and allow for easy replacement of the battery.
Also will the next phone have a user replaceable battery and expandable storage?
If not exactly, at least bring up the topic. What drives these anti-consumer practices?
The PCB has the flat flex connector at the edge, There is literally nothing preventing them from using spring contacts which are not only cheaper, but allow users to quickly swap the batteries, thus a backup can be placed on an external charger, if a user needs their phone to be at 100% of very short notice, or if they just want to replace the battery when it no longer holds enough of a charge.
