Unexplained battery Drain on LG G5

[Azaran]

So I've had my LG G5 for about 6 months now (not rooted), and recently from one day to the next, the battery started draining more than twice as fast. It used to be at 50% after 10 hours of fairly intense usage, but overnight it's draining 1% a minute.

- There's no difference in Apps usage from before (it lists Chrome as the main one, Android OS when idle)
- I tried restarting about 10 times now, even removing and readding the battery, to no avail
- Wifi on or off makes no difference
- I've made no new updates or installation recently
- Turning off active apps running in the background, makes no difference
- The battery is not overheating

I suspect the battery itself might be on its deathbed, but it's hard to believe that after only 6 months. My old Nexus 5, after 2 years, still held almost the same charge as when it was brand new.

Anyone else experience this?

Could be premature battery failure. If it's only six months, it should still be under warranty.

Does the phone get hot? If so, you might have a stuck process or bad app. If the phone stays pretty much the same temperature, shows the same power use under system>battery, then , yeah, it's probably the battery failing. Sometimes they just go like that. Did you ever let the battery discharge completely and then let it sit for a while? That could damage a Li-ion battery.
