Does your battery seem to drain rather fast?

[Kashton]

I just bought a Sony Xperia X and I have noticed that my battery is draining pretty quick. Is anyone else facing the same issue out there?

Sony Xperia X have the same feeling hope update 8 oreo solves it

I haven't tried to flash it yet. Right now I'm trying to decide whether to go with the X or upgrade to the X Performance. What do you guys think I should do. I can the X Performance for only 299. That's a steal at that price but so was my X for only 199.

Yes ofcourse it drains faster than before. It holds charge from 9 am to 4.30 pm them it just turns off. If anyone says flashing, safe mode, stamina mode once again then I'll beat them to death. I didn't buy my phone to do all the above for all issues. I bought it to use normally. But it becomes worse after every  update
