Improving htc desire battery life.

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

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

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.

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.
