fommy.com 1600mAh battery

[neemz]

Hey Guys,

Thought i'd make a post to warn everyone away from buying this battery.

The battery does not perform as well as the standard 1150mAh one.

My testing criteria are.


Brightness to 100%
Wifi on
Bluetooth on
Wireless location on
GPS on
Screen timeout: Never

Then I leave the phone on the Status page in settings so that I can see the battery %, I then leave the phone alone and don't touch it at all. I occasionally write down the battery percentage and time.

The first test I did on the standard battery which has had 6 full cycles of charge and drain. The first test on the new battery is when I first got it without it completing any cycles. As you can see the two tests on the standard battery outperform the fommy battery significantly even after the fommy has had a chance to "callibrate" with 4 full cycles. (note one is missed out as I actually had to use the phone one day and used it with the fommy battery so it got another cycle outside of test parameters.

Here is the data

thank for this,

ima wait for t-mobile to release an official extended battery.

i don't like 3rd party batteries.

[kvizzel]

totally^

don't want my phone to overheat/explode in my pocket next to my nuts.

Maybe u should buy the seidio 1400mah and see the results.

Its slightly larger and heavier than the stock 1150mah so I believe its legit.

I've gotten about 6 hours of continuous awake time (after conditioning) on the seidio so I think it gets an extra hour or so of battery life compared to the stock.

What do you think my chances are of getting a refund?

What do you think my chances are of getting a refund?

Not that good, I'd say. Though, you might be able to convince them by showing the tests to them? :/

I'd really be interested in having a similar test for the Seidio battery with 1400 mAh. Would anyone having one be so nice and do a test? :)

[techcrazy]

May be you can try some cycles. mine is 1600 bought from fommy and its giving far batter than stack and other battery which i bought earlier

[ggrant3876]

Bought the Seidio Innocell 1400 battery and have had no problems. Lasts 4 to 5 days with moderate use. When charging it is a cool as a cucumber. n The stock battery was getting hot so called HTC and received a replacement for it. Haven't tried it yet.

[SilleeString]

4 to 5 days??? That sounds kinda long...

[alextrox69]

i got the sedio as well..the 1400 one..im testing it now...im on my first cycle and it seems to last a little longer...keep in mind i had the phone for 3 dsys so i cant really compare lol

[Essenar]

I too am interested in a vigorous testing of the Sedio one as well.

I checked out batteries on Ebay, but just couldn't believe that a battery costing $13 that comes with the back cover would do me any good on my MyTouch.
