I love posts like this and usually wouldn't respond but at the risk of sounding like a 'rabid fanboy' quite simply, you have a faulty phone.
1) I use my phone like a smartphone every day and the stock battery see's me happily between charges, always 12 hours+ (even before i was rooted) and i have used my phone as a Satnav whilst connected to my in car bluetooth many times, have never had battery drain whilst plugged in.
2) BT works fine here on every device i've tried including phones, laptops, sat nav, in car audio etc Only one from your list i haven't tried is a printer.
3) HTC Sense has never crashed for me whether rooted or unrooted. If you're using any sort of task killer then this maybe your cause
4) Before the OTA update mine got hot under heavy load but since updating and with every ROM i've used since rooting, it has been fine.
5) I guess sharing my experiences makes me a rabid fanboy and a knuckle head too but i can live with that
6) If the phone was too big for you, why did you buy it?
No doubt you're going accuse me of being a fan boy blah blah blah but do us all a favour and spare it. These are my actual experiences with the phone and whilst i don't disagree there are faulty phones out there, there are many more out there that will agree with most if not all of my statements above.
And i can google my name and get around 20 million results, this doesn't mean they're all about me
Actually, all good points.
1) The first full day I had the phone I was at 50% battery by 12:30pm. In that time I sent 5-9 texts, browsed the web for about ten minutes, and downloaded one app. I also tested the navigator b driving to the local Waffle House for breakfast with my wife. The phone was originally unplugged about 7:45, so we're looking at 50% drain with fairly minimal usage in under four hours. Contrast to the iPhone 3GS, which is a slight apples/oranges comparison (This phone DOES have a faster processor and larger screen, after all). The day my Mom-in-law brought her iPhone home she went an entire weekend without charging it. My belief is that you don't add a faster processor and larger screen unless you have a battery that can cut it.
Even after the "seasoning period" that a modern battery shouldn't need, the phone was usually down to 70% or less by 11am from being unplugged at 5:45am. This concerns me the most because I coach football, and the most necessary time I have to have phone access is the end of the day, when we're either on the field practicing or at a game. If a player gets injured at 5pm, I NEED to have phone access to get EMS to the field. I can't say, as the employee at T-Mobile put it when I commented on the dismal battery performance "Welcome to smartphones, dude."
Currently, I have the 1900mAh Anker and it has helped a lot. However, I can still count on losing 3-5% battery while reading during the first twenty minutes of the school day. (I'm a teacher, and we have a silent reading period every morning. I read using Moon+ with the screen set at 3% brightness in nightmode to save battery.)
GPS navigation eats this battery like a sandwich. It's very frustrating, because I really like the navigator over my Garmin single use device.
2) I opened another thread about my Bluetooth problems. I'd love to have your input on it. I may be doing something wrong, but I admit to being a little aggravated when HTC Tech support tells me, "Yeah, it doesn't do that." Then I find out from YOU that it DOES. At this point I trust you, faceless internet person, more than the company that MADE the dang thing!
3) You might have just solved this problem for me. I have ZDBox installed and I can't remember if I set the task killer on it or not. I usually don't due to the battery drain, but it's been installed for a couple of weeks. Let me monkey with it and get back to you. THANKS!
-- ZDBox Task killer was set to kill tasks at <50mb memory. I turned that off. I'll let you know what happens. I appreciate that tip!
4) Mine gets the most hottest when I'm using GPS, but I notice a temp change even when browsing. I should turn on the temp monitors and put the widget from ZDBox up to get some data, but I haven't gotten around to it yet.
5) You're not a knucklehead. Sorry if it seemed to be personally directed at you. My Amazon review of the phone brought a lot of people out of the woodwork who's most enlightening comment was "Yer dum and gayz dood! LOLZ!" I found the same thing came about when I reviewed the original Kindle and said, "This thing holds 2,000 books, but doesn't allow you to organize them? Basic common sense EPIC FAIL!" People created Amazon accounts just to tell me that they've never in their lives ever needed to organize their ebooks and I was dumb for wanting to do so.
In point of fact, I appreciate the honest counterpoints. The OP needs BOTH sides to make an informed purchase, and who knows? There's a good chance I'll be swayed to your point of view. I WANT to like this phone. I certainly spent enough money on the darn thing.
6) When I purchased the phone I had no idea what kinds of accessories were available, and my previous three phones were prepaid cells I'd stuck my SIM card into. This was the first brand new phone I'd purchased since 2007, and I was not particularly familiar with smartphone extras. Cases and clips and car mounts are sold all over the place.
I did some research on the phone itself, but not much into the accessory list. For example, I looked around at Walmart and Target and saw chargers with microUSB connections all over the place. What I DIDN'T see or discover until after I purchased the phone, is that a charger pushing less than 350mA makes the phone do some bizarre things: screen response is erratic and typing produces random characters. That's not really something you can find out on the web. (Fortunately, I didn't pay for that charger. My boss gave me one he had lying around for another device.)
My assumption, based on the evidence proffered at the time, was that most smartphones were about the same size, so the cases you find scattered all over in Walgreens and Targets under signs that say "smartphone belt clip" should fit, right? Well, they don't.
It's easy to forget that this particular phone is larger than the average and weighs more, so things like the bendy holders won't support it. The charging port is also located on the side, and most car holders grip from either side, making it impossible to plug in and put into the holder. I went through six before I found one that worked properly. (Humorously, it was the cheapest one I found. The $35 one didn't work, the $6 one did. Go figure.)
Further, the phone is about to get bigger; I have a Mugen battery en route, and as you're probably aware, it comes with an extended backplate for the phone because it's so huge. I'm not upset with the size of the phone, per se, but with the lack of places to PUT it. It doesn't fit in a pocket very well, and if you can't find a belt clip, what the heck do you do with it? (Particularly given that I'm a PE teacher. I have to have my phone for emergencies, but I wear athletic shorts 95% of the time. A belt clip was sort of necessary for me.)
As for your final point, it doesn't make and sense. Seriously, Googling the EXACT PHRASE, with quotes, "Problems with HTC Sensation" returns 24 million hits. I think we can assume at least some of them are in regards to the HTC Sensation, and not the Space Shuttle or Washington Monument.
So, I don't think you're a fanboy. You like your phone. That's fine. On a personal note, I'm glad it works for you. So far it hasn't worked well for me, but hopefully with some advice from you and others it'll work BETTER.
I appreciate your dialog.
