[Review] - Extended Battery

---

Ok, here is a little review on the extended battery (2800 mAh) and its bulky back casing.

comparing the extended battery casing and standard casing, and the batteries:









in my hand:


physically, the back casing fits nicely...yeah it makes the TP2 more bulky and yeah, you'll notice the bulk. but, i need the extra power....

Physical Review
The extended battery is heavier than the standard one, so, its not just adding the extra bulk but also extra weight. If you are already used to the weight of TP2, you wont notice the extra weight but you will immediately notice the extra bulk!! Surprisingly the back casing sits firmer than the standard casing, i dont experience the usual "accidently opened casing" using theextended battery casing. The material is plastic with a glossy finish, similar to original casing (quality is still questionable thou), sadly, the color is light grey so it makes the coloring uneven. A darker grey would be better. The extended casing will add an extra around 3-4 mm to the device. I did not notice any difference in the sound produce by the extra casing compared to the standard one. the volume keys works well, the mute button also does the job, glowing only on the side gaps. The stylus hole is too deep, its a pain to get the stylus out. But hey, i dont think I ever take out the stylus except only when I have to do a softreset.

Performance
I need to let you know that i'm a very heavy user of the device. Using standard battery on EDGE, i usually get 9 hours of juice, sometimes less (4.5 hours standby, 4.5 hours usage). When i turn it to HSPA, it would go for only 6 hours. If i use automatic, it will go in between. My test on the battery is using the automatic for the first cycle, EDGE and HSPA will be added later.
Test result:
Automatic setting: 14 hours
EDGE only: 17 hours
HSPA only: 10 hours

Looking good there.... I predict for normal usage will add extra 1-2 days of durability.

and oh yeah, i bought it here...

Maybe you could mention it's a 2800mAh battery in the first post.
Wonder how long the battery lasts. I get about 3 to 4 days with my Vario V wich is a lot for a WM device

thanks mate, just edited it,
my standard battery last me for 9 hours so i'm hoping it would last me more than 15 hours

Seems like a pretty heavy device to me. Since the original TP2 isn't really light when you get it.

added performance review.

forgive me for asking, but what exactly do you do on the device that drains the battery that quickly ?? i get by about 3 days on standby, 36 hours with cell radio on, 36 hours without. a little bit of wifi and text messaging and around 15 minutes of phone calls each day, give or take a few minutes.

Just a guess, but probably the GPS is the problem. That, on any phone, EATS battery capacity rapidly.

There's a new SiRF chipset - v4 - due out soon, that allegedly combats this problem, but we won't be seeing that in phones for at least two generations yet, due to design, prototyping, pre-production, production, and lead time to market issues, of course.

i would, however, jump on this if htc released their own official battery pack with a proper battery cover.

does ne one know if this will fit the cdma version (telus) touch pro 2

Isn't the extended battery WIDER than the original? How does it fit in then?
