s5 heats up so much

[bbmjack]

Is it normal for it to heat up after 30 seconds and charges to slow at OEM s5 charger

Depends on the temperature. For it to warm up some during charge / gaming sure .. but otherwise it shouldn't really unless some rogue app is causing the processor to run harder than it should.
