EC TECHNOLOGY 2300mAh Li-ion Battery review

[anon(848791)]

EDIT: The review and testing of this battery has ended. It did provide a little extra juice. For $10 it was great. I will not be checking this thread again.


Had this battery for about a week now. So far so good, seems like I'm getting more use out of it. It doesnt seem to heat up as much as the original one.

How's this for the stock battery. Make sure you look at the screen on time.

Don't get me wrong, I still love playing with my gs3 but when it comes to going out and not worrying about carrying a charger or battery pack, the gn2 can't be beat. :thumbup:

So far every night I have about 20-30% left after a full day of use. I also compared this with the battery that came with the phone by using it for a few days. The result is that the original battery has about 10% or less of charge left by the end of the day So far, this has been a very good battery.

That is super, especially for a phone with a screen that large. But you're also rooted, right?

I have been looking for an extended battery that wouldn't double the size of my phone, and this looks like it'd work great.. But from what I understand, you would have to remove the EC battery from the phone to charge it? Or am I reading too far into it?

I'm pretty sure this will not double your batter life, just give it a little extra juice. If you want to double your battery, then get the 4000+ thick battery.
This, ec battery, works just like original, so no need to take it out for charging

 

[kodybrannon]

is this an extended battery? or just a replacement?

Depends on your definition. It's the standard physical size battery, so it doesn't need a new back, case, or other accessories. But it claims to be 2300 mA capacity, as opposed to the stock battery's 2100 mA capacity. Assuming the claim is accurate, that's a 9.5% increase in capacity and, presumably, a 9.5% increase in battery life per charge.

its a replacement extended battery. fits into the phone with stock cover without a problem.
so far i have gotten good results with it. i have ordered the samsung 3000mah battery, so im excited to see how long that lasts.

 

[HULKchampion]

stas333 ? where did you order the Samsung official 3000mah battery? I saw ebay, but figured if there were other options (cheaper?). When you receive your 3000mah, can you please post pictures of before and after? I would like to see how much thicker it gets.

This battery has no NFC, right? Most of the third-party ones do not. Anyone have experience with a brand that does support NFC? I found a couple options on amazon:
regular - Amazon.com: Onite 2300mAh Battery with NFC for Samsung Galaxy S3 SIII GT-i9300, compatible with i747 (AT&T), T999 (Verizon), i535(Sprint) + Charger: Cell Phones & Accessories
extended - Amazon.com: QCell Samsung Galaxy SIII X-Life 4200mAh Extended Battery + Blue & White Back Cover (Compatible with Samsung Galaxy S3 GT-I9300, Sprint L710, Verizon I535, T-mobile T999, AT&T Samsung I747, U.S. Cellular R530) ***NFC Support for S Beam an
