Accessories 3500 mAh battery from Seidio

dguy said:
Seidio's 3200mAh battery was actually 2600, so why would their 3500 actually be 3500? I don't think anyone actually believes that it is really 3500. That said, it probably still has more capacity than the 2150. The real question in my mind is if the battery will last as long as a name brand one. There's no shortage of reports of Seidio battery users saying the battery's capacity degrades extremely quickly over a couple months.

I would love for someone to do a comparison of battery capacity between the 2150 and 3500 as soon as possible. Then do it again in 6 months, then again in another 6 months and see where they are at. It would be best if both batteries were used as evenly as possible.

I'll do the test if someone provides the SEIDIO 3500 battery.
 
I could only imagine what the back of theirs looks like if they dont even show you a pic.

I haven't found one either but at least they give an mAh figure that's probable.

1550+1550=3100. It's not as if Seido is making custom cells, they're just stringing two 1550 batteries together and sticking it in a plastic case.
 
I posted this in the other thread about this battery. I'll post it here too in case some people are only following one of them.

Ok, it got here. To tell you the truth its not that bad. I does in fact still fit in my pocket. It has the same nice soft material that is on the original case. The shape seems to fit well in my hand.
Here are some pics (click to enlarge):








OP(and others): feel free to put these in your first post or do whatever you want with them.
 
Post Up Time & Awake Time for your first usage, please!

Then, if you want to post real numbers for everyone to assess the battery, make sure to ABUSE it! :)

It would be great if you could post some usage stats, but please try to state parameters:

wifi on/off
BT on/off
3G on/off
auto-sync yes/no
screen brightness approximate %
talk time

Also, what charge cycle # (1st, 2nd, 3rd...) did you run the test on, and if you did the battery trickle charge "trick" (phone off, charge until light is green, unplug/replug, repeat a few times)

Sorry to be a pain, but I'm curious how much better this is than the OEM 2150 mAh from HTC.

Thanks a ton!

My plan is to start the first charge before I go to bed tonight and not unplug for at least 8 hours. I will just take it off the charger once without reconnecting and go through a day and use all the radios except bluetooth because I have no BT divices. I'll turn on a live wallpaper. I won't charge the phone until it dies. I'll post the battery stats at the end of that time. Heck I'll even leave wifi on even when there are no APs in range just to see how the thing holds up(to simulate usage of the "notify me about open APs" feature). Anything else?

Edit: Maybe I will turn on the BT radio to see how much it eats but like I said I have noting to connect it to. I'll leave it on auto-brightness like I always do (I don't like bright screens in the dark)

Signal strength on the WAN Radio is the most important - its almost as important as Screen Brightness. But the screen brightness will go off in sleep, where the radio - might SPIKE continuously (polling/broadcasting) if you're low on signal from the tower.

Also the autosync timings against your e-mail accounts as well, if you never have them check will result in a different set of data as opposed to the checking for mail every 30-60-90 minutes type scenarios...

Everyone's usage can be so different - that these tests are really tough to quantify.

No, I'm not missing the point - I am making a point;

People will talk about how great this battery is, then others will buy it, but everyone needs to understand that there are so many different variables that impact your experience with a battery vs someone else's that expectations need to be set.

That was all.

I'd still love to test this battery - but I've already bought too many to test at this point...

hought it was 3500??

i see your point but you have to realize that many of us wish to know if it is THAT much better than the 1550, 1750, 2150. With the difference in pricing it is a big deal. All mentioned are bigger than stock but there is a 65 dollar difference in price from 1550 and 3500

I believe that the SEIDIO 3500mAh battery is two of their 1750mAh rated cells in parallel.

If I am correct, then they need to really do some serious work to make sure the both cells get charged and don't fool the charger into thinking the battery is fully charged in the event that 1 cell is charged faster than the other.

It would almost be more promising if they made a larger cell.

good point, would love to put the 3500 through the rounds.

I thought we'd already established that their 1750 'rated' cells are really only 1500 mAh? Other than that I'm sure this is correct. That would make the true rating for this battery pack around 3000 mAh.

Well, the number 1 rule about lieing is remembering what you lied about.

If SEIDIO are saying their 1750 is 1750, then if they put 2 in parallel then thats 3500 :)

Now people seem to believe that their 1750 is really 1750, so I was just following along with the Manufacturer Specified Cell Ratings. Not what I believe the rated specs are...

:)
 
If it's two cells, I'd feel pretty confident they stuck a small balancing circuit in there. There are also single-cell 3500mah batteries out there, not sure about the form-factor matching up to that battery tho (although Li-Ion batteries can be made in just about any form-factor/shape). I just know the 3500 cells I used to use in my RC planes wouldn't fit in the back of that phone cover, lol.
 
Has anybody measured the difference in overall thickness between the phone with this battery versus the stock one? The possibility doesn't seem too remote that Seidio will actually make a case to fit it (certainly more likely than that Verizon will make one available!), and I'm curious whether there is any chance it might also fit a Dinc with the 2150 mAh battery (which seems to add a hair under 5 mm). Of course, there's the difference in shape to consider, but at least we'd know if the answer was "maybe" or "definitely not"!

I would feel confident that did a balancing circuit too - just not confident in the lowest bidder to make it work right..
 
Here is a direct thickness comparison:

915210844_Nbmpm-M.jpg


Measuring by pixels, it is a 72% increase in thickness, not accounting for the camera sticking out with the stock back. I do slightly notice the thickness difference in my pocket, but I like the extra chunkiness in my hand - but I have huge hands so I'm probably not typical there.

I charged it overnight, took it off 6.5 hours ago and it's still reading 70%, and that's with a 1.5 hour walk with GPS enabled for RunKeeper tracking. Using wifi at home the rest of the time with constant twitter reading and some internet radio. I forgot to check up/awake time before switching for this picture, so I'll have to do that tomorrow.

Very pleased so far, I'd be well on my way to my second charge already with stock batt.
 
No one fesses up to their bull#$%@ unless you call them on it. I have used Seidio batteries in the past with my BB storm and yes it did give me better performance( although the battery cover was a plastic piece of crap). I suppose Seidio never thought anyone would check their spec and how true they are. I suppose they don't think consumers are smart shoppers, Ebay does not exist and China can't crank out the same battery for a 3rd of the price. I suppose companies don't lie. YEAH RIGHT! Come on Seidio I hope for your sake you can back you s@#$ up cause if not you guys can KICK ROCKS! I know all the users of the Incredible out there long for improved for battery performance but don't get taken. BTW I ordered two 1500mah batteries + wall charger for $10 free shipping and handling. Yup $10.

Did you do any charging in the phone with the phone OFF after it already showed GREEN while the phone was on?
