This is definitely a follow on to my most famous post on rooting HTC Dream: http://erlern.wordpress.com/2009/06/23/rooting-htc-dream-singtel/ . When you have successfully done so, your immediate joy of being able to run so many programs and modified ROMS on your set will be short lived upon realising that the paltry stock battery of 1150mAh cannot last for long. And then you will hit another snag and begin to pout. Well, that is until you hear me out 
~
I have been finding for an extended battery to be used on my HTC Dream (of 6 months old edy). It has been disappointing for me to search for a reliable battery source that is as advertised. I remember going all the way to Setapak and even further on the hope of getting an advertised 1600 mAh battery only to find (at the last minute when I am there) that the advertisement was wrongly typed; it was the normal 1150 mAh which they intended to sell for RM80 – 90. Sigh… it was very disappointing (twice disappointed, mind you!).
Which is why I am finally happy to find that the Chinese-made battery by Andida, rated at 1600 mAh, is as advertised. A 1600 mAh would give you a marginally increased usage of 39% over the original. Calculations are simple… 1600-1150 = 450. When compared to the original 1150 = 39.1%. The original stock battery which my Dream came in usually lost about 20% after downloading a 100+MB vidcast episode via 3G. But on this battery, I found that it was only a 7-8% (with screen brightness set at the highest!).
The other improvements in having an extended battery instead of the stock is the lack of heat emanating from the battery cover (lower part of the HTC Dream) which I constantly get when running 3G for long periods of time, while browsing the net. It is now at most slightly warm.
So yes, I would recommend this battery to ALL HTC Dream users. The upside besides the extended juice is the fact that it does NOT require an ugly battery cover to cover up the improved battery size! I get to keep the original size of the phone, although it is slightly heavier (not too noticeable). But that added weight just confirms that the battery packs a lot more ‘ommpph!’
I can get some if there are any who are interested No more false advertisements.
[...] extended the battery of my HTC Dream by using 1,600 mAh Andida branded batteries. Have a read here: http://erlern.wordpress.com/2009/11/03/extended-battery-for-htc-dream-singtel-set-1600-mah/. For those who successfully rooted their phones, may I suggest that you flash Cyanogen’s ROM. [...]

Hi erlern,
Getting my HTC Dream in a few days time, late to the party, but been browsing ur blog abt the rooting and battery.
Where did you get this battery and how much?
Thanks.

Rayvolvez: You can try to find it from ebay… just put in Andida. If you can’t get it, let me know… I can get it for you.

Thanks erlern!
My phone will be arriving tmr. Have saw some reports that it doesn’t support chinese language input and that you have to hack it for it to support, is that true?
BTW, if I want to root my phone, can I enlist ur help, I can pay a token (but perhaps, let me know how much you charge.).
Thanks for the response.

Rayvolvez:
By itself, I don’t think so. But you can download some applications from the Market to give you Chinese input (simple not traditional).
Rooting your phone? I wish I could help you, unfortunately, I am in KL (Malaysian). I think you would be Singaporean from your IP address. I’m sure you can go to any major IT complex and ask them to do it for you
For a price of coz. All the best!

Oh… Thanks for all the responses.
I was worried about the chinese input as I do need to communicate with chinese.
Thanks for the suggestion, guess I will try to follow the instructions u posted and hope u dont mind me constantly asking you questions：）

Rayvolvez: No worries… I would suggest that you check your firmware (version number for phones) on your HTC Dream and see whether it is a 1.6 (aka Donut) or 1.5 (aka Cupcake). If it is 1.5 then you can use this faster way to root your phone (http://theunlockr.com/2009/08/22/how-to-root-the-mytouch-3g-or-g1-in-one-click/). If it is 1.6 (then you need a bit of a detour, and do this first before doing the above: http://theunlockr.com/2009/07/05/how-to-unroot-your-t-mobile-g1/).
It is tedious (yes… I admit it is)… which is why I would recommend that only geeks & computer savvy people who can follow instructions to follow down this pathway
If not, then send it to a phone shop (I am sure it will not cost that much… I think) or just rely on Singtel’s ROM that they loaded onto the new phone 
All the best! Btw, nice graphic designs you have

thanks erlern!
will keep you updated.
Its cupcake atm, the update arrived as soon as I connected to wifi.
BTW, does 2G network means no data? I have disabled “data roaming” too, have wifi everywhere I’ll be, so did not get data plan.
By: rayvolvez on November 18, 2009

Rayvolvez: 2G means only voice & SMS (although technically it’s 2.5G). Leave that uncheck. And uncheck the Data Roaming (if checked it means you are communicating using data your personal data plan while overseas).
Good, you can use the ‘1 click’ solution.

Have created a blank apn so it doesn’t connect at my pocket’s peril. LOL. My previous htc touch would connect and burn my pocket even when its locked.
BTW, are you familiar with google pinyin? I can’t seem to switch between languages.
Sorry for bombarding you with so much questions. I’m noob with this.

Did you install the Google Pinyin IME? Enable it in “Settings” > “Locale & text”… and uncheck the “Android Keyboard”. Then you will be able to use the Pinyin input when you use any applications that uses the onscreen keyboard.

I find that when I disable the android keyboard, I can’t use the onscreen keyboard anymore.
Not sure if its “google pinyin ime” i installed, found only “google pinyin”.
BTW, if you don’t mind, can you add me on msn xoco(at)rayvolvez(dot)com , easier to ask you questions and chit chat. I do hope to ask lesser and lesser questions soon
