Thanks, nice find.  Have a cookie on me.

It was recently posted in the "How To" section as well.  Normally I'd merge the topics or delete one, but in this case I'll make an exception.  

I'm going to try it myself.  If it works, I'd prefer to have both topics here, as it'll double the chances of people finding them.

That doesn't mean people should start posting it in every section tho  Wink

------------------------

EDIT : here's the basics, as explained by DeanoG

1. Power on your Desire then connect to your Charger and Fully charge until the LED changes Green.
2. Disconnect your phone from the charger and then power off.
3. Reconnect your phone to your charger with the power off and wait for the green LED.
4. Disconnect the phone from the charger and power it on.
5. Once the phone has fully booted / ready to use ...  power off again.
6. With the power off connect the phone to the charger and wait for the green LED.
7. Disconnect from the Charger then power on and use normally.


Anythng is worth a go ...  it does not work for everyone ..   Give it a go and let us know if it worked for you ...

Indeed, no difference here too.  But there are too many stories of people seeing really big improvements, so I'm not going to discard it as a fable.  I mean, you can imagine a 5% improvement, but people are talking about almost doubling their battery life here.  That's not within the margin of error anymore, that's a substantial difference.  And it's not just one person who claims such numbers, several people have noticed similar improvements.

I have a feeling that Android might calibrate the battery automatically over time, which could explain the massive increase in battery life in the first week.
Basically this procedure might be just a trick to let a fresh OS instantly learn the battery's possibilities and limitations.

While going through the procedure, I knew that it wasn't going to do much for my phone.  I started with an empty battery, charged it completely, then I powered off the phone and plugged it in again.  The green led came on immediately.  No need to wait.  That was the first signal.
Then every time the procedure said to "wait for the green led", it came on immediately as well.  That's basically when I knew that mine wouldn't improve.  A full battery is a full battery.  If the calibration was off, it would have started charging at some point in the procedure.

Gave it a try yesterday...unplugged the phone at 4am.
I consider myself as a moderate user, 20 mins call, 1 hour playing games, 2-3 hour music, few sms, few mins browsing the market..
Today at about 10am the phone was at 9% after 35 hours..
I would say that it improved my battery life, but not double it thogh..

The most impressive thing is that after unplug the phone, from 4 am till 7 am (the same day) it still remain 100% on standby mode.

your phones connected to USB and charging, however not being classed as 'plugged in' on the htc system, surely that means that your getting a little extra charge?

correct me if i'm wrong just taking a stab in the dark

I have applied the suggestions from this video and went from about 12 hours battery life to over 3 days! Well worth a look.

how often can you calibrate the battery? will it effect the battery if you calibrate it more than once?

Just once is enough...

Once should be enough.  However if you perform a factory reset the calibration settings are lost, which means you need to re-calibrate it if you ever need to reset the phone.
