SEIDIO 1750mAh vs. HTC OEM Batteries...

[DustinF00#AC]

It's been a long month. I am not sure if everyone is familiar with or even cares about the thread I started - SEIDIO - Liar, Liar, Your Pants Are On Fire... - Android Forums - You should give it a quick run through to see where this started from. Obviously once the folks that couldn't see the writing on the wall from the posts in that thread and because I used my real name and likeness - I felt the need to prove it.

All the testing was performed with a battery charged in the SEIDIO multifunction charger and then "Bump Charged" in the HTC incredible I own. The power source for the HTC incredible was the stock charger that came with the phone.

The charging and testing was meant to duplicate real life / real world scenarios. The batteries were charged over night or during the day (depending on what cycle the tests were at) and the bump charge was done. Minutes after the bump charge was done the testing equipment was set up and the battery was tested.

This is what you would do if you were using the battery as your main battery - which I was attempting to do.

I tested the SEIDIO 1750 mAh battery I bought Directly from SEIDIO and also another one I bought from Amazon. I also tested the 1300 mAh Stock HTC battery, the 1500 mAh HTC TP2 battery and the HTC Extended battery for the HTC Incredible.

Here is the chart for all the tests performed. You can see that I wanted to test some more - but the data was consistent enough that I felt confident in being open and showing it earlier than I had originally expected.

We also had a heat wave in NY and I couldn't test during the day - which slowed me to only testing overnight where the temperature in the room was nicer and cooler than 80+ degree I started to see.

Finally, I needed a place to post some of this stuff and I have been working on a place to post a bit of the "diary" of the testing and stuff. You can find the screen shots of the graphs from most of the tests in above chart here -> Battery Blog Post ? Testing Set Up ? Randomness & Photography I had only used this dot-com before to host some photos of the Opie & Anthony Comedy Virus tour that hit NY in 2007 - but I figured this oddly named dot-com might be the best place for some of this random data and posts...

I am open to testing other HTC incredible batteries if you would like. I will also refund you shipping to me if you would like.

If anyone would like testing of other types of batteries - I ask that you purchase two of the SEIDIO Multifunction battery charger plates for that battery and send it to me with your battery. I will ship you back your original battery, pay you for your shipping (if a receipt is included in your package) and also pay you for the SEIDIO MultiFunction Battery charger plates you send me because I will not return them after I have soldered them for the testing.

I hope this helps out the community...
I see that drPheta posted this in the general chat - but I'd like to get this into the HTC incredible section considering the batteries tested were specific to that device.

the false advertising bothers me, but I think I may pickup a 1750 anyway.

If it's true it sucks. What I can say though is rather it's 1500 or 1700 I still get twice or better out of my 1750 than I did the 1300. So in my eyes it should have been rated a 2600 or maybe the 1300 should have been considered a 650 lol.

Quite the finds. Glad I didn't waste any money on the Seidio battery.

I think the most glaring item is the revelation of the battery cell information contained in the 1750 battery. The test only goes on the prove that the 1750 is by no means accurate. While all the other batteries outperform their ranking, the Seidio falls WELL short.

Something tells me we won't, but it'd be nice to hear from SeidioSeidio for a little explanation here.

I get twice as much from my 1750 also, numbers don't make sense (well at least in our case)

I concur, but I will take his test results like I did with batteryboss's with a grain of salt. I am a bit bummed with the result people are getting testing them, but I know I got 2-3 times the life of the stock 1300 so overall I'm happy and got what I expected.

Another thing I just noted is that the final test of the 1750 read 1618? If that's true the battery is getting 92% of said capacity. Do you plan to test past that point to see if it improves?

One other comment that's kind of got me thrown off is the quote:

I also won’t be able to let batteries “rest” for 24 hours before testing them, because, in reality you don’t do that – you charge and go.

And I hate car analogies, but I have to.......kind of like saying I know when you tell me the new mustang is 300HP but you dyno it at the engine, what comes out to the rear tires is only 240 HP so your car is only 240HP. These test have just got me thinking a lot about battery testing techniques. I need to talk with the guys at the R/C shop again and see how they are testing their LiPos and see if they can test my battery and tell me anything, or any better way to check this stuff out.

It's tough really. I've still been testing the batteries and can't get the SEIDIO 1750 to rate higher than the previously posted results.

The OEM batteries seem to retain very close to their rated if not above values...

Obviously your experience and phone variables are impossible duplicate - the SEIDIO battery seems to be closer to 1600 mAh rated - 300 more mAh can be a lot of standby time.

I just figured I would share this with the forums - its very amazing and frustrating at the the same to see so many get different data out of their 1750mAh SEIDIO battery and not seeing it myself.

The under the covers issue is just nothing but more confusion as to what the cell is really is.

Well the thing I've got bugging me in the back of my mind is do we actually know what the C rating of the battery is? I know you tested at 200maH and 150maH but is that the actual discharge rate of the phone? Not sure how much it would matter but if it's like C/1 or 1/5 the battery capacity it would be 1750/5 = 350maH discharge rate which would rate the battery lower etc.

At 150maH/250maH it would put it at a different C rating, which may be whats happened between their qualification of how big it is and how it's actually turning out. Saying they aren't telling the full truth kind of thing. Just something to think about.

Well the C rate is tough to decipher because of the cut off voltage. The phone thinks batteries are dead when they hit 3.5 volts. When I run the SEIDIO battery at a 1.750 A Discharge where do I place the cut off voltage ? at 0 ? do I go lower than the circuitry will allow and let the circuitry cut me off ?

I tested at 250mAh in order to compare my results with Battery Boss but I also felt that was too high a discharge rate. I decided to move to 150mah to see what happens.

It still doesn't explain why at an equivalent discharge rate an OEM battery can rate close to or equal to its rated value and the SEIDIO battery misses its mark.

C rate is just a discharge rate. C/1 would mean that I should 1.750 A in a hour for the SEIDIO and 1.3A for the HTC Stock and 1.5A for the HTC TP2 and then 2.150 for the HTC Extended. Then all the numbers change according to the difference in C rate.

That's the way I am reading the battery book I have.

Right I get ya about the C ratings. The cut off voltage I would believe would be set to the predefined rating that the phone cuts off the voltage and thinks they battery is dead. However it wouldn't suprise me one bit if an after market producer did it to 0 voltage because they want to rate their batteries as high as possible. I would like to see it discharge down to 0 just to see how close it would be to 1750. There is so many different conditions that the battery can show a different maH it's sad. And not all manufactures rate them the same way. What you are doing is very interesting and has got me really wondering about the battery, even though I'm totally happy with the performance. One thing I would note too, is my 1750 last longer than the 1500 I tried too, by a couple of hours. So I'm still not totally happy with the reports back from people. Something just isn't adding up somewhere, almost like there is 1 variable somewhere that isn't being tested. I have no clue if it exists or not.

Hello, GREAT research, btw!

I have a question...

some folks here...
NEW OEM BATTERY HTC HERO IMAGIO SNAP TOUCH PRO2 TILT2 - eBay (item 160456674641 end time Aug-14-10 09:37:49 PDT)

have found success using a touch pro2 battery in the Incredible.

do you guys know anything about this?

NEW OEM BATTERY HTC HERO IMAGIO SNAP TOUCH PRO2 TILT2 - eBay (item 160456674641 end time Aug-14-10 09:37:49 PDT)

could there be anything "bad" about putting a "non-Incredible" battery into the Incredible?

Exactly why buyng a HTC certified battery gaurantees it's performance. I remember others talking about Seido's shady marketing and false advertising before.
I'd love to see results on the Seido "3500Mah"(quotes used with extreme prejudice), it's probably only a 2600Mah or so battery in reality.

Thanks for the testing exposing Seido's false advertising
