so what you're saying is that you essentially have to replace the cut part of the wifi antenna with a similar size piece or it increases battery drain due to having to power a larger antenna?

Gotcha. Good info.

I'll try a few variations.

exact same dimensions. also the layout changes how it receives signal. some layouts will point in a certain direction, others 360 degrees, others 180 degrees. Without going into too much radio physics, best to leave the antenna alone, improving its connection WILL boost performance.


a good analogy would be, a subwoofer in the car sounds awesome, and at that right bass frequency youll feel EVERYTHING shake and rumble and you love it. well that special bass note is different for each car/sub box. Your antenna works the same way, its designed to be the right length to resonate (rumble) at the frequency you use to connect with, if you change its size, you change the frequency its good with. It can still work, just not as efficiently.

May as well give this a go, Anker 1900mAH battery can be had off eBay now for 7.99 and battery door for 2.15, so 10.14 for what should be a huge increase over a tired old stock battery.

Screw all that messing about....i'm gonna buy a Genuine HTC Desire HD Stock Battery, so then i'll have one in the phone and a fully charged spare battery in my pocket/wallet/car/house/bag or whatever, for when battery dies.

We need to order a extra better cover in order to get the metallic connections and not destroy the original phone's cover?
are all parts at Ebay (Chinese or european) the same?

Got mine from Hong Kong, stock OEM battery door. Works the same as the original one. No drop in wifi performance. Too bad the original one got pretty used up, the copper strip fades away.

thank you for fast reply.
Could you show me a photo of the wifi mod?
Concerning post 98 with the DIY procedure, it doesnt really look nice how the chinese guy has the wifi antenna at the external side of the phone.
If this is how the phone will look like at the end, then I dont find any point to try this whole procedure.

Unfortunately, that is the best way to do it. There is no other way other than that except for the external antenna. I didn't do it because it is so ugly. After cutting out the battery door, I've put my previously used gelaskin to cover up the battery. It blends well with the mods. Too bad the skin got peeled out accidentally, and I've lost it forever. :'(
Now I seldom use it except when I have my casemate tough with me or going out for long trips. Will upload the pic if you insist, but it is just the same as the previous post with gelaskin on it.

Xmm, then I wouldn't need the photo.
I checked carefully all photos of this topic and I see the OP and some others without external antenna. Especially with the the round cutting door, the antenna is between the battery and the cover, and so it's not visible.
I only wonder how you people cut so nice the thick plastic of the cover. Any tips on how to remove antenna from cover in order to add it later with the new battery? And how is the connection of the antenna with the golden pins? Just by touch or they need somehow to stick them together?

(p.s. ordered already anker battery +2 covers )
