Seidio 1600mAh extended life battery
I've just received the Seidio 1600mAh battery, and I'm interested to see how it performs, compared to the HTC original.
The instructions say 'please allow 8 hours for initial charge'; it's just charged fully after 3 hours 45 minutes. It also says 'performance will increase after 5-6 full charges.' I'm looking forward to my performance increase.
Apparently Seidio batteries operate at about 80-85% of stated capacity... I guess this is within industry standards.
Unfortunately, the stock HTC batteries seem to operate at over 95% of stated capacity, so these Seidio batteries actually have less capacity as standard than the battery you just replaced.
The only thing that puts me off the spare battery is the way you have pull the cover off the back of the desire - Seems somewhat fraught with danger every time I do it - Keep thinking it will just break in half.
In the end i plumped for the Nexus Power Portable Pro from Mobile Fun for 19.99. Downside is that it is not as neat as just popping in another battery, but upsides are that it won't destroy the back of the phone doing it, it really is a nice small form factor, and i'm hoping I'll get two phone charges out of it. Seems to work ok at the moment, but only had it a day so far. Useful to power my son's PSP and DS and wife's ipod as well though, so seems quite versatile.

I hadn't read that report, but I did google the battery, and there are many (inexpert) results where people say they got more out of it than the standard battery; but not, I admit, from specifically Desire owners. I don't know where HTC source their's from, but if they are unusual in working at a higher capacity, that might explain it.
Well if you email Seidio they'll probably tell you themselves that their batteries operate at 80-85% (Mugens have already admitted this).
Whichever way you want to look at it, that puts it at less than the capacity of the HTC batteries (which I agree appear to be unusually high quality).
Any anecdotal reports of these seidio batteries lasting longer than the HTC ones at the same usage rates are wrong. You cannae break the laws of physics.
You see the problem is, 80-85% is actually not the worst rating. Some third party batteries could be as low as 60%. The proprietary batteries are the exception here...
I've emailed them anyway and asked if they can give me an idea of what the actual operating capacity of their batteries is. Hopefully we'll get some confirmation.

I've just phoned Mobile Fun, who I've always found to be decent and honest, and they say they haven't heard of this, but didn't deny that it is possible. I have seen that there is someone called Jazz from Mobile Fun who frequents this board, and the guy on the phone said that he'd draw Jazz's attention to this thread next time he sees him. I'd be interested in what he might have to say.
(They did emphasize that they have a no questions asked 30 day return guarantee, which is one reason I buy from them.)

For those that are interested, I've recorded my battery level, using an app called Battery Snap.
The use has been what I'd say is light/average - and obviously none when I was asleep overnight.
I fully charged the Seidio for the first time yesterday.
During the night my phone uses about 4% of the battery on standby, deduct that from your total and you've got about 31% from waking hours, so you're using maybe 2% an hour.
With medium to heavy use and wi-fi on most of the time, my stock battery drops at an average of about 4.5% an hour.
So if you're a light to medium user like you say, I'd say that's just about right (and the bump in usage from listening to music is about what I'd expect from my phone too).
Can you tell us what you've got running? Is wi-fi/3G on? Brightness level? Active wallpaper?
For my 4.5% I've got active wallpaper, brightness at 15%, wi-fi on about 60% of the time.

I've changed to BatteryTime Lite, as it measures in single units.
18.45 - 57%
I'm currently disabling wifi, mobile and gps until I want to use them. Screen brightness is on auto.
I'm going to do this twice more, once with the Seidio and wifi, mobile and gps permanently on, and once with them switched off with HTC battery.
There are many threads in several forums about the Desire's battery life - many of them not very happy. I think it must be recognised that if you have a multi-faceted device with most of options on, your battery life will not be great. At the moment battery development has lagged behind the demands of the devices they are powering.
If this is born in mind, and some of power saving measures (like the ones I'm using above) are implented, two days usage is not unrealistic and is reasonable.

I fail to see how these % are relevant, or need to be updated so many times. It would make sense just to post how long it lasted till the next time you have to plug it in no?
Plus if you are going to do the same 'test' with the standard battery you won't get a correct result as you'll not use the phone exactly the same, so you could end up with less or more usage and a respectively better or worse battery analysis.
It would be kinda the same if I said now that my standard battery has 68% left after 1d 1h 44m 50s. (which is more than your seido had after this time). But it wouldn't be relevant at all cause we obviously did not have an equal use of your phones over this time.
I don't mean to come of as rude, I just don't see the point of posting your battery % every hour or so.
That being said:
Standard battery 1400 (100% capacity) vs Seido battery 1600 (100% capacity)
The seido will last 14.28% longer.
This is if you consider both batteries to run at 100% capacity of their claimed Mah (1400 and 1600)
That being said this isn't realistic.
Standard battery 1330 (95% capacity) vs Seido battery 1440 (90% capacity)
Seido will last 8% longer
Standard battery 1330 (95% capacity) vs Seido battery 1360 (85% capacity)
Seido will last 2% longer
Standard battery 1330 (95% capacity) vs Seido battery 1280 (80% capacity)
Standard battery will run 3% longer
Standard battery 1260 (90% capacity) vs Seido battery 1280 (80% capacity)
Seido will last 1% longer
--
It's already been reported in this thread the htc batteries are of great quality and run at 90-95%
We are unsure of the Seido batteries but realistically they will be around 80% (and thats a very generous number considering other manufacturers go as low as 60%)
If you then look at the calculations above you'll see that the difference is marginal.
So again, I fail to see the relevance of these updates as you won't use both standard battery and seido battery the same way.
A relevant test would be installing a flashlight app (that turns your screen white on the highest brightness setting) and (after killing all other apps and turning off wireless, 3g, bleutooth and go into airplane mode) then timing how long each battery takes until it is dead.

I am sorry. As it's pointless, and I can see that it probably is, I'll stop updating this.
Well i was interested.... I was looking to get the extended battery but will wait to see what info Jazz reports back with.
Thanks NineToTheSKy for the effort and info and thanks Celox for that very interesting breakdown . Maybe we need HTC to make an extended battery..
If you keep a fully charged spare battery available, what percentage of its charge does it lose each day. IE - if I kept one for a week from fully charged, what would be its value at the end of the week? Also, can you charge the HTC batteries outside the phone?
With regard to enabling/disabling connectivity, I'm still not 100% clear on whether, if I leave both 3G & WiFi enabled, the 3G is turned off when it finds a WiFi connection. The 3G icon disappears from the status bar but does this mean it's as "turned off" as it would be if I did it manually or could I make additional power savings by switching it off myself?
No idea, but I'd imagine once it's gone from the bar it's just off. It seems to take a moment to start up once you switch off wi-fi, so at a guess I'd say it's off, and that the option just tells the phone to switch it on when there's no wi-fi available.
Where is Jazzy Jeff with our update, I wonder?
HTC tell me that the info on their batteries is correct. No word from Seidio, though I suspect they might be less than forthcoming, especially since they're already aware of these tests...
This is my response so far:
"I talked to the Product Team. Please let your customers know this
information:
Prior to using your new extended battery, please allow 8 hours for initial
charge time. Performance will increase after 5-6 full charges. Approved
chargers like OEM or Seidio chargers should be used."
Hence, why I have not really responded yet - I'm still pushing for a better answer. Bare with me, I am not quitting yet.

Thank you Jazz . I'm very interested in this as it was one of the items on my wish list...
It doesn't have specs yet, but might actually have higher capacity as it's bigger - of course you have to use their special back plate as well though, but might be good for when you know you won't be near a charger (i'm thinking festivals etc). Anyone used one like this? Are there other makes of oversized batteries for the desire?

Their customer services team say they haven't got specs yet - "normally however the extended batteries are approximately twice the mAh of the standard battery"
No word either on size/form - but i'm interested in any case, so will keep an eye on it.

I'll be keeping an eye on this.
I bought a similar type for my Hero, it was twice the capacity and came with a perfect-fit rear battery cover...it does make the phone thicker but that's no bad thing in my opinion and it makes the phone feel a bit more substantial in the hand.

I think the delay in getting a response on this tells its own story!
If they had anything to brag about it wouldn't be taking them a week to reply with something as simple as confirmation of the battery capacity, and they wouldn't be sending obfuscating messages like the one Jazz received.
They didn't reply to my very polite request for info at all.

extendig the battery life sounds great. I make it through the day, if I'm not using my HTC desire non stop. But downloading apps, using GPS, playing flight director, listening to music... its only a few hours. I wanted to keep a spare charged battery in my bag in case I get stuck away from a power socket! Does anyone know how long a spare HTC (or other battery) would hold its charge?

The response that Jazz quoted isn't much of a response: it's from the instruction sheet that comes with the battery. Word for word.

To get a meaningful result, as it's impossible to replicate usage patterns, I'd have to fully charge the Seidio and leave the phone to completely discharge, without using anything on it, and then do the same with the standard battery. As that would mean not touching my phone for possibly four days, that's out of the question: I need it too much.
So I think the only sensible thing to say is: if you believe that official report, then the Seidio isn't worth buying. If you don't: then the choice is yours. For me, the best case scenario is that I've got a spare battery that might last longer; the worst is I've spent about £10 more than I needed to.

A simple way to compare the two batteries is to fully charge, then do something you can easily replicate AND that uses a lot of power.
For example:
Disable wifi, 3g, gps (because you cant ensure both test runs would use the same amount)
Put brightness on full
Play a movie - repeat till battery dead
Make a note of how long each lasted - I imagine it would only be 4-6 hours like this?

As we haven't heard from Jazz for a while, I'm assuming that Seidio haven't got back to him, which suggests that they can't justify their claims. I mean - how long can it take for them to send him data proving that their battery does give 'extended' life? If the battery does what they're claiming, they would have the data to hand.
So, if the above is correct, the battery isn't as advertised, and MobileFun should correct their description of it, both what they imply, and what they state:

designed for the customer who needs extra life
There is one independent report that says the battery doesn't give extended life, and the manufacturer hasn't refuted it. Why?
For my 4.5% I've got active wallpaper, brightness at 15%, wi-fi on about 60% of the time.
Your Wi-Fi consumes 60% of the whole battery drainage?
I don't remember I saw mine go over 20%. It's in a 13-15% range.
On the other hand, the System consumes up to 60%, display 15-16% (at the first notch of brightness as set with the HTC Power widget), cell standby at 13-15% and a phone standby at 2% rate.
Oh, and yes, as someone already noticed, Desire's battery cover looks like it was not meant to be opened twice a day. For that reason I decided to skip buying a spare battery (at least the one of the same capacity) and go with a high capacity external charger, such as this one.
The HTC Desire is one of the latest high end phone by HTC bringing a huge 3.7" inch high quality AMOLED screen for crystal clear viewing, powered by a 1 GHz Qualcomm Snapdragon processor and runs on, you guessed it, Android.
