    Ok, so I ordered the 1500 OEM battery from igonemobile.com. It was cheap, and I'm not willing to wait for the 2150, nor am I willing to believe the 1750 from Sedio gives the specs they claim.

    So, I ran a non-scientific test. First I made sure that each battery was in the phone and charging for at least 8 hours overnight while at 100% (green light on, batterygraph says 100%).

    I turned off all radios but the mobile radio and shut off sync. Then I set brightness to max and turned off the auto adjust. This was to eliminate as many variables as possible.

    I set batterygraph (the app) to record the battery state every minute.

    I then started Pandora with a pair of headphones plugged in and removed my phone from the wall charger. I did this at approximately the same time both days (I think there was 1 minute difference). I went through my normal day, but I left my phone on my desk at work all day and just let it play music over the mobile radio through pandora into the headphones.

    I got 32,400 seconds of play time on the stock 1300 battery. (60 second increments)
    I got 37,260 seconds of play time on the 1500 OEM battery I ordered. (60 second increments.

    *I did have to place and receive one call on the 1500 battery. Total call time was ~30 seconds. And I received 2 text messages. Nothing I could do, I have to use the phone sometimes*

    So, I got a 15% increase with the 1500 battery over the 1300 under the most controlled conditions I could produce while being reasonable. 1300 to 1500 should give a 15.3846% increase, but I'm willing to chalk that up to sampling error or phone call, or text, or whichever due to how insignificant it is.

    I'm not trying to determine how many AH a battery has without testing equipment. I'm simply comparing other batteries to "stock" rated battery, and making the assumption that 1300 AH is a true figure. If someone would like the data captured by battery graph, please PM me and I'll send it to you.

    It does appear that the 1500 sold by Igonemobile.com is indeed 1500 AH, assuming the stock is indeed 1300. I would like to see the Sedio figures in a similar test. I'd be willing to do it, however I would want a battery shipped to me and shipping both ways paid for by Sedio (I.e. I'll guarantee that the battery is returned on my credit card, but I don't want to have to pay to ship it back). Or someone who has the 1300 and the Sedio that is willing to do a similar test and give their ratio relative to the 1300 would be good too. I think the best way would be to test all 3 battery's on the same phone, but I don't know anyone who would buy BOTH after markets.

    Let me know if you see any glaring flaws in the test I did. I'll elaborate if possible, and admit poor procedure if applicable.

    Your biggest flaw is not testing the Sedio.
    then asking for it to be shipped to you with-out you paying,.

    whats that about.
    :confused:

    I'm not asking for a sedio, I'm saying the only way I would test it is if it were shipped to me (credit card secured....if you're ever done an advance exchange you'd know what that is) and all shipping charges to and from me covered. Otherwise I'd rather someone who owns it do a similar test. I wouldn't buy a 1750 battery for the price they sell it even if it was exactly the AH they claim.

    No, I do not want a Sedio battery. I don't want it free, I don't want it paid for, I don't want it with green eggs and ham.

    I would be willing to do this once I get my Incredible. I've got my 1750 sitting in a drawer waiting for the damn phone to be delivered.

    As long as you're willing to do your best to control the conditions and don't have a "I bought it it must be worth it" mentality it would be greatly appreciated. You can discharge faster by leaving the screen on at full brightness or something, but just avoid using stuff like GPS or WiFi that may change based on location.

    I honestly do want to see the stats for the 1750 since I really think the stats are way over stated. I could be wrong...but I'd most likely have to see it for myself to be sure.

    It would be nice if an organization like Consumer Reports would do an article on batteries and the claimed vs actual specs. I was very pleasantly surprised by my own results....I figured I would be on here bitching out the retailer, but got a surprise.

    I would do it but I use my phone, I mean I think you performed a decent test but I'm not sure i could replicate it. If you live close I'd let ya borrow mine for a couple days, I have spares.

    I wish I bookmarked the page I saw it on, but someone did some very robust testing on a whole bunch of batteries.

    It is a fact that Seidio lies about battery sizes. Their batteries that are the same physical size as a stock battery but claim to be more mAh are actually smaller than the ones that come with the phone. The Seidio 1750 battery is probably smaller than the stock Droid Incredible battery.

    An example that I explicitly remember from the article: The Nexus One comes with a 1500mAh battery. Seidio sells a 1600mAh battery for the Nexus that is the same physical size. Testing showed the Seidio 1600 battery to actually be around 1300. Testing showed that Seidio's 3200mAh Nexus One battery was actually around 2600-2700mAh. If you buy the absolutely gigantic Seidio batteries, you will get a pretty large increase in battery life. If you buy their batteries that are designed to not make your phone bigger, you're just throwing money away.

    I have no doubt that the Seidio 3500mAh battery will completely solve anyone's Droid Incredible battery woes, just don't expect the ratings Seidio claims to be spot on.

    I don't know if Seidio lies about the batteries, but all I can say is I personally have experienced a difference between the stock battery an the 1750mAh battery. So, I'm happy, you can choose to believe me or not, I could care less.

    In any case, I hope HTC release some OTA that fixes at least the charging issue, and better battery life is always welcome.

    I think you are referring to Battery Boss, which is the only one there is that says the Sedio isn't what it claims, I don't find information from just one source reputable, especially this guy, he basically says he is jobless and bored, either way, one guy's test isn't conclusive to me, so believe what you want.

    Having said all that, I have the stock 1300 and the Seidio, 1750, and completely unscientifically, I haven't noticed much if any difference between the two, I'm thinking that the battery is NOT worth the extra cost.

    Yeah Battery Boss was it. I've personally owned the Seidio 3200 mAh battery and while it made my Nexus last a lot longer, I didn't feel like it was a full 100%+ longer. People I've spoken with on other forums have had mixed results. Some who purchased Seidio 1600 and 1750 batteries experienced slightly longer battery life times and some didn't notice a difference. Considering that, it's possible the longer battery life that was noticed could be placebo. I tend to think Battery Boss' results seem pretty accurate.

    Here's a link to his site if anyone was interested:

    I just purchased a 1500mAh OEM HTC battery, should be here in a few days. Although I get a full day (take it off the charger at 7am, and have like 8% when I plug it in at 11pm), I want some extra power, I think the 1500 should do the trick. Thank you for your little test, it helped me sway my decision to purchase the battery.

    Ok, perhaps people are misreading what my point is here.

    1) I don't care if you like/dislike Sedio.

    2) I'm not contesting that the 1750 battery advertised will last longer for you then the 1300 stock. Hell, a 1350 lasts longer then a 1300.

    3) this is the forum for the Incredible. I would like to make a thread addressing ONLY the batteries that work with the incredible.

    4) if you feel that the sedio 1750 battery is significantly better then the stock or the 1500, please do a real test. Remember, however, that you will be challenged by people who don't have a "I bought it, it must be great" attitude.

    5) I'm not saying the Sedio 1750 battery is better or worse then the standard 1300 battery. I don't care honestly. I can only speak for the battery I tested that was 15% better then the stock battery....as advertised. I'd like to see some REAL reviews of the 1750, but IMHO it won't matter for purchase as the price per AH is too high anyhow.

    In all reality, I don't care too see a dick waving competition. I'd like to see some real numbers. I wish there was a way to get rid of trolls and dickheads, but there's not....unfortunately.

    No, the battery I ordered was from igomobile.com. I'm not supporting them as a business. Just telling you where I got the battery I tested. I would enjoy seeing stats vs. the 1300 stock battery from other locations.

    And yes, if your question is does it fit fine, it does.

    No probelm.

    The battery I ordered was

    Verizon HTC Touch Pro 2 Pro2 Genuine OEM Lithium Ion Standard Battery

    It cost $16.99 no shipping.

    The battery fists in my "standard" case. Plus my Body Glove case still fits. Hope that helps....I'm not telling you to buy this. I jhonestly just want to get some real numbers on the battteries together...and there seems to be 1 patricular company that refuses to tell us how they test or what their real numbers are.

    That's fine. No on denies that' you get better then stock performance. Please provide some figures though so we can compare to other batteries. If you only get 10% better performance then 1750 isn't a real number....it would be 1430......Unless you argure that the 1300 battery is better the spec.

    Battery life is super subjective. Everyone uses their phones differently and there's way too many factors in how quickly a battery depletes. I would love to test the Seidio 1750 mAh battery, but I can't because I actually need to use the phone, so I can't replicate your test conditions. I can only report what I achieve on the battery on a day to day basis, which goes back to my point of everyone using their phone differently. ;)

    Usual everyday scenario (w/ Seidio 1750 mAh battery):
    - Plug in phone to charge at 11:30pm-12:30am when I sleep
    - Unplug charger at 7:45-8am
    Conditions: GPS off, BT off, 3G on for ~1-3 hours, WiFi on for the other times 3G is off, Autosync on (push 2 gmail accounts, exchange), display ~40-50%
    - Call usage: ~5-10 mins in a day (yeah this is a work phone :cool:)
    - TXT usage: anywhere from 15-30/day (always on AIM/gTalk throughout the day)
    - Listen to music (on local player) for 2-3 hours, using stock HTC player w/ playlist.

    Results: Anywhere from 5-20% when I plug it back in every night, so that equates to about 16.5-17.5 hours (stock battery would last about 12.5-13.5 hrs). Even my day to day usage varies depending on what I have going on at work, and I how often I use the phone. So, hard to say. I do try to minimize as much as possible using the phone's display, but sometimes it's hard not to play with the phone :D

    So is it worth the 3-4 hour battery life at best from the stock? For me, yeah it is, since I pay squat for monthly charges on this phone :eek: (thank you company!), so the investment of a cheap battery was worth it.

    The 1500mah oem HTC batteries can be bought directly from a corporate Verizon store. They are 40 bucks retail price, 30 if you get a 25% discount like I do. I got shafted buying one on eBay, and after that I went right to Verizon and got one. It seems slightly better than stock.

    I actually have 3 oem HTC batteries and an external battery charger for my Inc now. Two 1500's and my stock 1300.

    But that's the beauty of this test. I'm not asking you to have some special machines. If you REALLY want to test it...do this....

    Set parameters that won't change...brightness, radios off, etc.....for 2 days.
    Use the stock battery and get a "base" number. Let's pretend that' it's real.

    Use the Other battery (I don't care who makes is) and give us a % difference. It will take a couple days.....and to be honest it's hard to believe the hardcore "defenders'. I think a good number of people want a REAL comparison and not many companies are willing to do it. I'm not talking test equipment. I tried a "real life" test the best I think any real person can. If you have a better test, give details, please.


    I get the "real life" shit. I really do. But the problem is that real ife is different from day to day. Unless you want to pay for a real "scientific" battery test, best you can do is similar conditions for same battery.

    I also get the same corporate discount. I got the battery for $17 from igonemobile.com that I tested here....it would have been dishonest if I pretended different. To be honest, I thought their shipping sucked, but that's a different thread.

    I don't get the point of your post....please test your batteries if you feel they are better then the OEM batteries I got from Igonemobile. I got equivalent to 1500 over 1300 stats....are you saying that you got better then 1500 through Verizon? If so, please let me know, I get corp discount too.

    Dear god thank you for spell check or I would make no sense.

    I won't deny you there. However I think replicating the same set of static test conditions for two veritables are considered acceptable scientific test conditions. No , I'm not trying to replicate the conditions that Joe Smith uses....I'm simply trying to replicate the SAME conditions for each of 2 batteries that I own. Yeah, real life may be different....real life is also random and we can base judgments of "random" on known quantities...and you arrive at them by controlling the variables.

    The only potential flaw I can see in your test is recharge cycles. Has there been a difference in the number of recharge cycles on each battery?
