Seidio 3800mAh extended battery

Be careful with Seidio. Their batteries are often not the capacity they report.

I agree. My experience and some testing that was done tends to show that their batteries are usually about 20% over-rated.

That would put this battery at about 3000 mAh, a significant drop and something to consider when you think about slapping something huge and heavy on your new phone.

No NFC? Pass.

I agree. I will keep waiting for a larger extended battery that does support NFC. Until then, I am happy with my extended battery that I got from Verizon for $25, just wish there was a battery cover that only said Google on the back instead of Verizon 4G LTE (like the GSM).

Yeah Seidio's batteries generally don't meet their claims. Just note that MOST batteries don't meet the claims, just like most product specs in general don't meet the claims, mostly because specs are generated in ideal and optimum conditions which often times just aren't the operating conditions the devices are used in. Not making an excuse for Seidio, just saying in general, specs are not always spot on.

That said, even at 3000 mAh, this still more than 1.5x the original and almost 1.5x the Samsung extended battery.

I boo-hiss on the lack of NFC antenna, but I more or less expected that. I think our only hope of a beefy extended battery with NFC will be from Samsung, and I wouldn't count on that.

As far as aftermarket batteries, if there is an aftermarket battery maker to trust (i hate that word), it's Seidio. Their batteries in the past have proven to be safe. I'm also leery of aftermarket batteries and avoid them all, with the exception of Seidio.

Most OEM batteries meet their claims, which is why I always remind people about Seidio's exaggerations.

If you are putting in a battery that is 2x the thickness of the OEM extended battery on your phone, but you're only getting about a 40% increase in capacity (2100 mAh vs. 3000 mAh), that should be factored in when considering the size difference, that's all.

Also, it's important to temper expectations about what battery life improvements will be like. Again, since the OEM battery ratings are usually accurate, and Seidio's are usually inaccurate, you have the expectation of nearly doubling the OEM extended battery's life, with the reality that's nowhere close.

I find it ridiculous. The OEM batteries are usually extremely close to their rated capacity - there's no excuse for these aftermarket batteries to be so far off.

I've been a big fan of Seidio Extended Batteries outside of the crap 1750 they made for the EVO, Incredible and Eris that battery was more like 1400 but anyways I had the 3500 on my Incredible and it was amazing easily lasted double the 1500mah EVO battery I used . Was it 3500mah ?? I don't know but it wasn't any less then 3000mah . That being said I would buy this extended battery if it was at $40 but not $70 especially with no NFC (although I don't use it much if I'm paying that much for a battery it better have that) I'm not a heavy user so my 2100 battery is easily lasting me an entire day 7am-11pm . But the huge batteries are nice for times you're going to be away from a charger for a couple days . Right now I'll just carry my spare 1850

Exactly what I was going to post. If anyone is interested, some folks are testing batteries to see what their actual capacity is. In particular, check out the Seidio entries which usually run about 80-83% of reported capacity.

So if their past performance is consistent with this battery, it's going to be more like a ~3100 mAh battery. Still a significant jump over even the Samsung extended battery, but nowhere near 3800 either. But perhaps Seidio has improved things. :)

My recollection is that the 1750 from Seidio was only a tad thicker than OEM and didn't require a new back cover which was an astonishing feat...which turned out to be a farce as you noted. I don't know about other batteries they've made, but in this case, it was almost like a "law of conservation" issue. How do you get a 50% increase in battery capacity with a negligible increase in battery thickness? Answer: you don't.

Precisely. It's not like Seidio has access to a much better (in terms of charge per volume) battery technology than someone like Samsung. So size/volume should tell you something.

My question is how much space does NFC take up in the battery? Would not having NFC make a battery considerably thinner?

Could this Non-NFC extended battery be approximately the same thickness as the standard NFC battery?

No. NFC antennas (keep in mind, the ONLY thing that's on the battery is the antenna - it's not a chip or anything) are tiny. Adding one almost doesn't even increase the thickness at all. It's a paper thin loop of metal - the nexus S included it on the battery cover. A couple pictures for you:

Oh I'm not disagreeing with you, that's why I said I prefer to stick with OEM batteries. I was just pointing out that in general, many specs are not achieved in real life use and people should always be skeptical. Tested a printer's ppm lately? LOL

People definitely need to know that Seidio doesn't meet their claims in real world use, so an expectation of double the lifetime will be a let down!

That said, I personally need more juice than the OEM extended battery. I have 2 now which on normal days when I can see a charger midway through the day is fine so that I don't even have to switch to the second, but on long days, I will blow through BOTH of those batteries if I'm particularly bored that day, so for me, even if it's only a 50% increase in battery life despite 100% increase in size, it just might be worth it.

Or maybe a THIRD OEM extended battery would be the answer! That actually sounds like a better idea (and a cheaper idea)!

An extra battery is always double the battery life with no change in form factor, just another battery to carry, which for me is mostly not a big deal.

TRUTH!!!!

I think when the dinc came out, some of us took them apart, posted the p/n's and links to what the capacity actually was..... then seidio never, ever, responded on these forums when the capacity was much less than advertised.

Also someone did some amazing charge/drain tests in those days to also support the findings.

So if it's 3800mAh, it's probably around 2200mAh :D:D

The battery has no chance of actually being 3800MAH. That said, it will still be significantly larger than the 2100 that is available now(It is reasonable to expect it to be over 3000) so it is still a good choice for those who would like even more power. Don't expect this to be thin however. Double the phone's thickness is a reasonable expectation. A worthy sacrifice to some depending on how bad they want the power.

Thank you for that information. I just figured the reason they stuffed it into the battery was they couldn't fit it into the phone. Just seems kinda weird to put something like that into a part of the phone that may need to be replaced on occasion, when it looks like it could easily be placed under the battery without an issue. Looks like Samsung has the battery market cornered for the GNex with the people who need NFC. I don't really see a need for NFC at the moment for myself.

The problem is that it can't be placed under the battery. The battery interferes with the NFC signal.

They have to put it OVER the battery. That means they either need to redesign the battery door, making it complicated, prone to breaking, fragile and finicky (because the battery door can bend and would need to have some kind of electrical contact with the rest of the phone, which it doesn't naturally have), or they can put it in the battery which is strong, doesn't move, and ALREADY has electrical contact with the phone.

The battery is the smart place to put it. The antenna is a cheap, tiny part, easy to design into the battery, and doesn't require significant design compromise to the phone.
