This is my first Instructable.  It is simple, cost me no money because I had the materials in my shop, and was quick.  It worked so well I thought I would share.
After buying an aftermarket extended battery for my HTC Rezound cell phone I noticed that my reception was terrible.  The battery was thicker than the original battery and came with a new back cover.  I discovered that the circuits and contacts in the new back cover were just thinly applied copper colored paint.  I inspected the original HTC back cover and saw that it also had conductive paint, but much thicker.  This is how I improved on the cheap aftermarket back cover, resulting in greatly improved reception.  The entire process took about 20 minutes.

Step 1: Materials

The only materials you will need:

About 4" of foil tape.  I used aluminum because it was in my shop, but I suspect copper would be better.
A hobby or craft knife.
Transparent tape.
(not shown) a fine tip pen or marker.  I used a Sharpie.
A pencil with an eraser.
<p>Yeah, great idea. I tried mobile signal booster to improve the signal (and it really helps), but your idea is almost cheap what makes it super!</p>
<p>Well Done thanx 4 sharing.</p>
<p>The battery life improvement is only logical since the SIM card will try to connect, also if the connection is poor. This energy consumption gets even more explicitly visible when you have dual-sim (such as me where both sim cards have very poor connection when at home).</p><p>I'll try the tutorial and see what it does. Thanks for sharing!</p>
<p>Great Idea..Thanks for sharing :) :) :)</p>
