[ONE Q&A, Help & Troubleshooting] jamiethomaswhite:
Hey there,

I'm so tired of talking about this topic that I can barely work up the determination to write this response. I'll give it a go though and I'll try to keep it short, simple and leave as much emotion of as possible.

So I've had my phone 10 months now. It seemed great at first but it wasn't long before I started seeing cracks (not literally). It began with the battery, or lack thereof. These days it's much worse but even back then it was noticeable worse than any other phone I had owned in the past. I first reported this issue... 6 months ago.

I'll leave that to sink in a little, before telling you that even now my issues are still not solved and I am having to take OnePlus to Trading Standards and receive third party consultation and legal advice.

So six months I have complained and begged them to solve my problem. And in that time my phone has gotten significantly worse.

It exhibits the EXACT same problems as yours. Down to the last note.

The battery... *sigh* Oh the battery. It now lasts around 1 hour of heavy use, 2-3 of moderate use and a bit more otherwise. Even if I leave it completely alone I have to charge two to three times in a 24 hour period.

The CPU seems to be randomly throttling. Performance from app to app will be vastly different.

The heat that comes off this thing is obscene. At times I literally cannot touch the face of the phone or the camera lens they are so hot. (I remember recording some temps once at 47 degrees centigrade).

My messages generally either send or don't. Or maybe I don't wait long enough. I just usually copy the text and resend anyway.

I have issues with my touch screen responding. Funny I never had these or never noticed them when everyone was shouting about it. Now they've released a fix I have them.

Some Wifi networks do not work, they get stuck forever "Connecting".

The phone no longer rings, vibrates or gives any indication of incoming calls. Sometimes it'll pop-up on screen, sometimes there will be literally no indication even on screen except that my phone wakes itself up to the homescreen and then minutes later tells me I have a voicemail (which also has no notification sound/vibration)

As it is I have finally, just this last month been offered an RMA... YES that's right, it's taken them six months to own up to an issue and offer me that which is stated in my warranty and within my rights.

Unfortunately, for them, it is no longer good enough. I have applied to my bank to forcefully remove the money from them and return it to me. That is being decided with the evidence I have, by my bank at the moment.

After that, the ball is in their court and I am free of them as far as I am concerned.

I wasted so much time and breath on emailing and tweeting them and getting no responses, stock responses, blanket responses, repeated verification processes, remote flashing of Oxygen OS to my phone by an engineer (which has brought up more problems, mainly being that Lollipop and Oxygen OS especially are godawful) and general deflection and delay tactics.

They are one the most disgusting companies I have ever had the displeasure of trusting, purchasing from and dealing with.

I hope one day, they go bust and I never have to hear of them again.

Sincere apologies for my vitriol but it is not unwarranted or untrue and I cannot abide. I am extremely sorry you are dealing with the same issues, you are the first I have heard to have the exact same concoction as me. I'm afraid we may have defective (and dangerously so maybe) devices from the factory line, but no one will own up to it.
