Motivation for more exercise and weight loss

So I am disciplined in professional life, much as I had been in private life more of a "laissez-faire" attitude. I thus conditionally since but a few years something overweight've carried around with me, I ordered (motivated by friends and colleagues) the Jawbone UP24. Basically the concept is indeed quite simple: The bracelet recorded steps and stages of sleep, but may also be from the "normal workload" recognize different situations and "asks" per app, whether you were physically active, perhaps at some point in a special way.
Even though I was a bit skeptical about whether the bracelet gives me the necessary motivational kick, I can go for 10 weeks to say that I am completely convinced of the combination of bracelet and (iPhone) App.

To make it short: Thanks to the transparency with respect to movement, caloric intake and weight, I'm almost entered into a competition with myself: I am motivated to achieve its self-imposed (moderate) movement objective control my caloric intake so that I take fewer calories as I consume and also covers my weight daily. Result: I, I have already taken 10kg 10 weeks and I'm sure I would not have had the discipline of such a weight reduction without the visualization of data and raising awareness of the calorie consumption. The Jawbone bracelet has thus my "inner demon" infiltrated, exactly what's the desired effect.
Until my ideal weight I have to persevere a little, but the Jawbone UP24 is a good companion in this process and I am sure I will reach the intended target and especially the weight then can hold. The feeling of having made me a slave to technology, I did not, I see it more that motivates me the bracelet, to achieve an own goal and keep track of the way there.
Why did I deducted one star at a such euphoric statement? The reason for this is that in the first time, the battery life was very limited and that I could reach through a firmware update an acceptable battery life only, which allows a little more relaxed to experience the daily life with the Jawbone UP24 since one at the achieved battery life always finds a time slot for charging. I would have liked that I could get pointed out the possibility of firmware updates through the App, so I had (although it was not overly complicated) to find out the solution by search engine itself.
