[T-Mobile HTC One (M7)] 02CWRX:
See, I would call myself more of an "average user". I don't play games or anything, I just do the usual texting, calling, internet, etc so my Sensation with an Anker 1900 mAh battery lasted all day. I only have an 8 gig SD card that I use in my phone anyway. I stream music online, and only store a few local MP3 files. Most of my storage is photos/videos, and those are automatically backed up to my network hard drive everyday via FTP, so I can remove them from my phone as needed for more room. The main reason I liked the removable battery is because I like the ability to replace the battery if I had to if it stopped holding a charge, I needed to do a complete hard reset, or something along those lines. Then again, I suppose I could always take the phone apart to replace the battery once it's out of warranty, and if it's in warranty, I could just have it replaced. The more I think about it, the more I think I would be ok with the "fixed" non-expandable internal memory and non-removable battery.

I agree it will be biased, I just thought I would ask for input after citing specifics about the S4 that I don't like so users of an HTC One could give me insight on things. Especially those who have any comparison to a Sensation 4G or Sense 4.0 (I think it was) compared to the new Sense 5.0.

I have used the S4 for a few days now, and although it has grown on me in a lot of ways, there are still blaring problems that I can't get over such as the Bluetooth not working, and most recently it seems I cannot assign a static IP address to the phones wifi at all. I see people talking about being able to do it for the S3, but the option is not there for the S4 that I have seen. My home router DHCP is turned off and all my wireless devices have assigned IP addresses for various reasons, but I had to turn it back on to get the wifi to work on this phone.

I also don't like that I have yet to actually hear a phone call or text message while at work. It seems this phone is even quieter than my Sensation 4G in the sense that I at least used to hear calls and texts occasionally, but I haven't caught one yet with this phone. The vibration function on it seems weaker as well, even after customizing the pattern it vibrates in (neat option, by the way).

Along the same lines, the in call volume seems weak to me as well as it did on the Sensation 4G. Even with the "extra volume" button pressed when in a call. It only gives one extra volume "notch" on the scale. How is the HTC One in this area?

The camera is great. I love the way it takes pictures quickly, I like the effects, I like the panorama, I like being able to take still shots while taking video at the same time, I like being able to quickly switch from taking pictures to taking video with a simple tap on the screen and it starts recording automatically, etc.

I love how snappy the operating system is. I only see lags in a couple spots using the phone, or trying to exit out of certain applications quickly. It's definitely quick.

As for the lock screen that had confused me, it seems it's trying to be simple, but all it does is add confusion in my opinion. Rather than a message that says "swipe in this area", it just pops up a box to highlight the area you're supposed to swipe if you do it wrong with no explanation as to why the box is there. Also, if you have the lock screen icons enabled, you can swipe from the icons to open that app (makes sense), but then you can also enable the lock screen widgets or something along those lines which actually allows you to swipe to different panels (different from your home screen panels) even with the screen locked. One of the panels is a quick launch icon dock with 12 app choices in it you can customize. Seems redundant, but I guess you could pick which ever style you like (dock icons along the bottom or quick launch on another panel).

I also figured out the confusion about the other box that shows up if you swipe the lock screen incorrectly. It changes it from the lock screen mode to the panel mode (as I call it). This panel mode is what allows you to swipe between panels if you have lock screen panels turned on. If you don't have them turned on and you get into this mode accidentally like I did, it's confusing what the heck it's doing and why because all it does is create a box that swiping inside of does nothing (unlike the OTHER box which you are SUPPOSED to swipe inside), and gives you a little padlock icon at the bottom you can swipe to unlock the phone. Really, this mode shouldn't happen unless you enable lock screen widgets/panels because it just adds to confusion in my opinion.

Also, I disabled every single little "waive your hand to do this" feature, I played with them once and that was it. Too unreliable. About the only one that was remotely entertaining was that you can take pictures using your voice. This came in handy because my 7 month old son would smile when we smile at him and say "smile". Coincidentally, that's one of the key words that will capture a photo. This means when I say "smile", my son smiles and the camera takes the picture. Kind of cool. You can also control the music player with words like pause, play, next, previous, volume up, and volume down. Seems silly.

Anyone have any more thoughts or comparisons with the HTC One that I could consider based on what you have read about my experience with the S4? Thanks in advance!
