While these problems do not mean that they do a Note 7 and spontaneously combust, it does mean that they do an Apple and shut down when they still have 35 per cent of their power left.
It looks like they are suffering from the same shutdown bug that plagued the Nexus 6P where the device would prematurely turn off at 25 to 35 percent.
A few Reddit users are reporting that their Pixel devices are also suffering from the same shutdown bug. Some Pixel phones would prematurely shut down at or around 30 percent and would not turn back on until a charger is connected.
Vrski_15, who started the thread claimed that twice in last five days, has the phone shutdown abruptly while he was in middle of something. In both instances, battery was between 25-35 percent, and the phone under normal conditions should have lasted for at least next 3-4 hours.
In the case of the Nexus 6P, Huawei said that this was not a hardware problem but a software-related one. However, users found that the problem persisted even after downgrading to Android Marshmallow. This led Huawei to investigate further with Google, and although the company hasn’t revealed the cause yet, it is probably related to the problem that these Pixel users have been experiencing.
