Battery Life
I generally end up putting battery life details at the end, but to be honest it’s probably one of the most important things on a smartphone, and one of the more important points to explore when talking about the Sensation. This is the second dual core SoC we’ve looked at, and thus the results are even more interesting. Qualcomm’s MSM8260 also differs from NVIDIA’s Tegra 2 in how the SoC scales voltage and frequency. On MSM8x60, each core has its own voltage and frequency plane, meaning that when we’re dealing with a heavy single-threaded workload, the second core can slow down and lower voltage. On Tegra 2, there’s a single voltage and frequency plane across both cores. The latter makes a lot of sense for primarily multi-threaded workloads, since they can be divided across both cores, and voltage is lowered accordingly. Voltage scaling generally wins out in the long run, but right now things in Android have a single-threaded bias.
First up is our cellular web browsing test, where we load a few dozen pages endlessly with the display set to 200 nits until the phone dies. The Sensation posts a very impressive result here scoring a spot at the top of the Android charts.
Next up is WiFi, which is essentially the same thing as our cellular test but connected to an 802.11n AP until the phone dies. Here things strangely aren’t all that great. The Sensation posts a number similar to the cellular test, but compared to other devices doesn’t see a big jump in battery life on WiFi.
Third is the call test, which is pretty self explanatory. We have the phone in test call another device, and play music at both ends to simulate a typical voice call. That runs until the phone dies, and the display is off.
Finally is our newest test, in which we make the smartphone a hotspot, connect up an 802.11n client, and load four tabs of our page load suite alongside a nonstop 128 Kbps audio stream. This simulates a number of people using the hotspot pretty aggressively and doesn’t let the baseband suspend itself. The display is also off.
Here again we see the Sensation take an impressive top position. The comparison I’m looking at is between the Optimus 2X, G2x, and Sensation. As a reminder, the Optimus 2X/G2x both have a 5.6 Whr battery, and the Sensation has a 5.62 Whr battery. The sensation blows away Android competition in the cellular web browsing test and hotspot test, and delivers middling performance in the WiFi web browsing and call test suite.
Conclusion and Final Thoughts
I’m pretty impressed with the Sensation. In most ways, it sets a baseline for what we should expect for this upcoming generation of devices - a dual core SoC, fast connectivity, some sort of specialty display (either high PPI or AMOLED), and unique industrial design that makes the device stand out.
I feel like HTC always is sure to save its best execution for the international version of its handsets, and in this case T-Mobile did the right thing by not messing with it. Beyond the branding on the front and a couple instances of T-Mo purple in the applications list, it really is an international device. Even the band support is the same as the international edition.
The Sensation impresses all around, and has very few shortcomings. First on that list is the absolutely horrendous speakerphone, which seems to either have something broken or the gain set really low in software, and a much more minor second is the small gap at the top which lets pocket lint intrude. Other than that, the only thing I’d seriously change about the Sensation would be to add penta-band WCDMA support so I could buy one and use it in the USA on AT&T for my personal device.
If you’re on T-Mobile, the obvious phone to compare with is the LG G2x, which performs very close to the Sensation and has similar overall size. Where the G2x gets edged out is display size plus resolution, and battery life in some areas. There’s also the fact that the Sensation is shipping with Android 2.3, and the G2x still is officially 2.2, though that’s going to change soon.
Internationally, things get a bit more complicated, since the Sensation is up against the Samsung Galaxy S 2, which we still haven’t taken a formal look at. The competition is fierce, and I'm eager to find out (and maybe even settle) the matter of which one is better.

but is not 800-900MB not enough space thought with an 8-16-32 SD card as well (i be hard pushed to use 800MB of internal storage) samsung need all that space as they have there own app store that has 3-4 games that use a lot of space, most other phones have 800-900Mb free space nowadays, i guessing most samsung phones do the 2gb/6gb split with 8gb internal spaceif you was talking about cheaper phones like the HTC desire or some random 1.6-2.1 OS phones with 500-800Mhz cpus (that are still been sold what's very lame as they are Crap) i would agree with you 110-50MB of space is not enough even with A2D (that's only on 2.2+ devices)
i agree with the sound of the load speaker seem to be lacking on 2 HTC phones i have seen
samsung need to fix there GPS issues there is Zero reason that GPS should be flaky at best (the jumping between to points every 1-2 seconds)
---------------
i agree GPS should be tested and if the phone has less then 1gb internal storage it should be reported as it makes the phone have limited use

Having less internal memory on android phones is actually limitting the number of purchases on the android market. People like me would have probably bought almost all the games by gameloft and many other apps for work. But thats not possible now because of the crap apps 2internal memory policy on android and the equally crap stock app2sd move feature.The microsd cards are ok, but that does not replace the need for proper internal memory. I already have a couple of 4gb cards, a couple 16gb cards and a couple 32gb cards. Would have preffered a hot swappable card feature without needing to pull the batteries. But I guess the USB on the Go feature on the SGS2 is an alternative. My cards are mainly stuffed with office documents and presentations, teaching videos etc apart from a few songs. But still need good internal memory for apps (some games and other professional apps and loads of teaching apps for my child). Presently i am using one phone for me and another for apps for my child. If the internal memory was ok then i wouldnt need to keep switching between two phones depending on what app i want to use. Not everyone is interested in rooting and playing around with firmware. But the present internal memory hardware situation and crap app2sd stock situation doesnt leave one with much alternatives on android for people who need more internal memory.

Walking sessions showed the exact side of the road that i was on (google maps showed accuracy of ~10m) and during the tunnel test, it was able to get gps signal as soon as i was out of the tunnel.

Let's see some Mango chatter. Let's see a new and innovative mobile OS that has cool new features that no other OS does. Other blogs have raved about it, has Google paid you not to?kmmatney - Sunday, July 3, 2011 - link
I'm still waiting for a good real-life battery assessment for a phone. How long does the battery last if the phone is sitting around doing nothing? Can I squeeze 2 days out of it if I forget my charger on a short business trip? How much charge does it lose sitting on a nightstand overnight? I'm a current iPhone 3GS user, and can get up to 3 days of battery out of my phone if I need to. I have no idea if I can do that just by reading this review.JasonInofuentes - Monday, July 4, 2011 - link
So, battery life assessments are really particular to the user and even down to what day it is. Let's cover your specific questions first.-Battery life sitting around doing nothing: Well, what good is the phone to you if you're not doing anything with it? And, what is nothing? If you mean screen off and not handled (as I'm guessing you mean, does that mean it's also not updating e-mail, and other apps? If you have absolutely no applications periodically pulling data and you leave any of these phones untouched until they die then they will last . . . a really long time.
-2 days on a business trip: What do you do for a living? Again, if you don't have any apps downloading data periodically, you only ever use your phone as a phone and maybe a few e-mail sessions, then any of these phones should hopefully last that long.
-Sitting on a night stand overnight: See the first answer.
Don't look at these battery life measurements as an absolute, look at them as a guide. If you spend a lot of time downloading data on 3G, then make sure to get a phone that does really well in the 3G test. If 3G isn't your thing but you're on WiFi downloading data a lot, then grok the WiFi graph and pick something near the top. And if you're main use for the phone is voice calls, there's a great list of voice call data available to you. Not sure which you are? Well, it sounds like battery life is your bread and butter so just pick one from the top of the list and go for it. You've got at least two weeks to decide if it's for you and my experience is that the honeymoon period when people get new phones is about 5-7 days, at that point they'll either be happy or dragging their charger around with them.

Hello,Why so much emphasis on phone features and such, but little or no information
on the fundamentals , being able to make a decent phone call in various conditions ?
