Google I/O 2009 - Coding for Life -- Battery Life, That Is

Jeffrey Sharkey

The three most important considerations for mobile applications are, in order: battery life, battery life, and battery life. After all, if the battery is dead, no one can use your application. In this session, Android engineer Jeffrey Sharkey will reveal the myriad ways -- many unexpected -- that your application can guzzle power and irritate users. You'll learn about how networking affects battery life, the right and wrong ways to use Android-specific features such as wake locks, why you can't assume that it's okay to trade memory for time, and more.

I particularly liked the subtitle at about 10:55 into it: RSS -> asses

That's correct, gothboyvamp, but for youtube 'users' whom are partnered with youtube may have longer.

Check out my videos, learn java, build a calculator in 2 minutes!

Look forward to more tutorials, 150 videos at max a day! (and like 30 at minimum)

Please I need to know

does the number of contacts, messages & data stored on my device affect my Battery life?

Example:

2 exact phones:

the first has 10 contacts + 10 messages

the second has 1000 contacts + 500 messages + files saved but not in use "Static Data"

Do they consume the same mAh ?

Thanks

Please I am need to know, if you buy battery from some 1 how can u tell if it is been used or brand new using an electric multimeter?

For example if some one sold me a battery he used it for 1 year already,

if I test it it will give me the same voltage & everything,

But

when I use it I will find out that it does not hold charge for more than couple of hours

So how can I test it since beginning if it has been consumed or not?

Very important

I would appreciate if you can help me out

Thanks a lot

Feels pretty lame to compare that 3G only have only 300kb/s when the usual is 6Mbit/s (7.2Mbit/s is the maximum) on 3G and on WiFi at least 20mbit/s.....(I got 100Mbit/s at home for years and getting 83Mbit/s to my phone)...

lame comparing...
