battery drops too quick after setting password , pin, or fingerprint.

[jfr085]

i found it on my 5x with factory img of 8.1 8.0 7.1 and lineage and RR as well. wheni set a pwd or so, system cost 400ma(20% per hour) after screen locked. without pwd it is about 80ma.
My 5Xhas an expanded ram to 3gb and its light sensor and gyro dosent work and decoder chip has some problem.
What could bcause such rapid power drop? or had anyone see it ever?
Thanks.
