Yeah, claims to offer 15% more battery life. For $42, I'd buy 2 more spare batteries, and have 200% more battery life than normal, thank you very much

It will be interesting to see how this tests out, but 15% more juice over stock for 42 bucks does not sound too compelling... however at that point you've got TWO of them.

Incidentally, this will bring G1 more or less in line with iPhone and HTC Touch Pro battery capacities.

But if you're going to pay $43 just to have an extra battery...

I say, take the chance on CS shipping you another battery.

Then you'll have two of them right ?

I'll tell you what would be 'cool' to have -- if someone comes up with a modified cover that incorporates two more standard batteries operating in parallel. The phone would be thicker by the thickness of 1 battery, have 200% extra battery life, and weigh just another 100gms more. Not a big deal for mega-battery life.

Ha Ha!!!

Of course you have to factor in the cost of a battery charger for the 2nd battery.

What charger!?

lol, that's an exaggeration. Won't be that much thicker, but I'll be laughing at you when you run out of juice when my power meter hasn't even moved.

Any battery gurus know if this is possible with Li-Ion batteries?

iLOL

And I hate to be laughed at, but if it's worth the hardship...

I'll sign up

What hardship? If possible, the phone will just be thicker by another 4 to 5 mm. Now imagine being able to surf the web for 10 hours, non-stop. If that's not hardcore battery life, I don't know what is.

I wouldn't go down the path of a battery pack that hooks up via USB though. Running batteries in parallel is the way to go, rather than having the USB piggyback battery trickle charge the on-board battery to death :P

I'm guessing that this will probably require a recalibration of the battery sensor, but I need confirmation that this is possible

I like the idea of a thicker phone for extended battery life. I always thought that they should have sacrificed another mm or two to pack at least 1500mah battery in there.

Alternately I would go down the path of two batteries, but with a modified back that allows for quick battery swaps instead of packing both in there.

Thought of that, but suspected it might confuse the heck out of the battery meter and screw up calibration. 2 batteries, or 3, and we're all set for a couple of days.

42 bucks is too much...
I ordered a 1200 mah battery for 7 bucks with discount.... and it works and fits fine...
might order 2 more at that price and a battery charger so i can have 3 batteries in case of emergency

If I dealt with the "Wing" being thick...

I guess, I could deal with the extra thickness for outstanding battery life

anyone know where the stand alone battery charger is online for the g1

Hmm... good point about the battery meter, especially running 2 batteries with different capacities. If they were identical batteries and ran them down to the same point each time, that may work, but not all "identical" batteries are the same, nor do they degrade at the same rate, so over time the meter would get confused again.

Suppose it would be interesting if batteries and the meters were smart enough to recognize eachother and be linked by a code...

Are you referring to this....


http://www.wirelessground.com/g1cradle.html

nah there was one that someone posted that was on ebay that was just one piece no cord, just snap the battery in and plug the box into the wall..

http://gizmodo.com/5098998/t+mobile-...attery-charger
this one here is 17 bucks

but this is what i was talkin about - http://www.fommy.com/view-full-page.asp?skuno=82322

[ame="http://www.youtube.com/watch?v=GlLq-vZac_s&eurl=&feature=player_embedded"]YouTube - G1 Spare Battery Charger-Review[/ame]

I ordered this for myself and a couple of mates here in Dubai. Works like a charm

http://cgi.ebay.com/ws/eBayISAPI.dll...m=300276359547

saw that eariler... but the pics take for ever to load of that one image on the pc... dont know why...

but its a hell of a deal.. i might order that instead..

Yeah, I felt the same way too. Extra battery, extra charger and a cradle to handle the G1 and the extra battery. Note however, that the cradle holds the G1 in a completely upright position. It would have been nicer if the unit was tilted back, but that's not the case. On the upside, there's a cavity at the bottom of the USB connector on the cradle to accommodate the extUSB cover on the device.

Wow, I like them both

So which is worth my credit cards numbers ?

*Edit, $28 and it comes with both the US & European plugs/usb cord & battery

Compared to paying $20 for just the little box and cord

This is a no brainier...

:~}

Question...

Does it really matter if the battery isn't OEM ?

It probably does but not that much of a difference... but there's a standalone battery charger combo pack with 2 batteries for 22.50 with screen protector and usb cable(retractable) and lanyard for the g1. Free shipping too.. its on ebay I don't have the link on me, surfing from g1, but it was posted before

The Seidio battery should be in today. You all can order those cheap eBay batteries if you want; you'll ultimately get what you pay for, and don't be made at T-Mobile if your phone catches fire or bricks.

Seidio makes quality stuff and they back their products; I've enjoyed their batteries in all of my Treos, Sprint Mogul, and soon, the G1.

I bought the extra battery from the T-Mobile store last week that was "on sale" for 39.99. So I'll just take that one back and use this one.

you have no idea where they get their batteries from, do you?

i ask merely for information, of course

To answer you question about double batteries, obviously Seido has done this for several devices, and packaged it with a revised back cover. Two batteries wired in series would double voltage, two batteries wired in parellel would double capacity and would require re-calibration, yes. Obviously, the best scenario is to have the phone know it has multiple cells to use strategically, but obviously the second scenario works well, or Seido wouldn't be selling so many super-extended double battery packs.

By current phone standards, the G1 is already fat and heavy. Having "only an extra 4-5mm" packed onto the back for more battery life would be disgusting.
Look at the iPhone and how thin it is. Now imagine what it's battery life would be like if you could replace the battery in it with a higher capacity version. The phone would still be 4-5mm thinner than the G1 and it would have better battery life than our "extended" batteries will provide.

I'd also much rather pay $42 for some extra juice. If there's one thing I don't need, it's carrying around support paraphernalia for my mobile phone. I'm already irritated that I have to think about where my headphone adapter for my G1 is. How about it not dying on you in the first place and you not having to carry around special equipment for your mobile phone. How about we complicate our lives less.

A bigger capacity battery usually means it being larger. In my case, I'm prepared to accept a 4 to 5mm increase in thickness to go from 1150 mAh to 3450 mAh. In your case, you're prepared to accept a 2200 mAh battery (claimed) for no increase in thickness (unlikely, but possible). Different solutions for different needs -- I'd appreciate it if you didn't dismiss my needs so indiscriminately.

$6 Battery!

Hmmm, I see a 5th Brick on the horizon

You can't argue with people caught in the grips of iPhone envy. It's like another kind of envy--the more you mess with someone else's, the more you wish you had one yourself. I, for one, don't want a phone that's so thin in might absorb into my skin if I gripped it too tightly in my hand.

The G1's thickness is "disgusting"? How much do you put in your pockets, seriously? Sure, it's not the sort of magical "how do they fit it in there" kind of thing that the iPhone has, but isn't the reason we have G1s in the first place because we don't think Apple is the be-all and end-all of genius?

And regardless of that, what is the big deal about having a phone that you can actually feel the presence of in your hand? Does the thickness hurt your muscles or irritate your skin? If so, you may want to see a doctor, because last I checked, the human hand is capable of holding objects.

You can't wow your friends with how pretty your phone is if it dies while they marvel at its sexiness. And aren't you supposed to be looking at what's on the screen anyway?

I have tMob's portable recharger (basically a battery you charge, then plug into your phone to transfer the power for like.. $23 I think)

It gives about 1 full solid charge tot he phone. At 1/2 the price this will remain my solution, even if it is a goofy pain in the butt to recharge.

Or, you can carry the Energizer dual-AA cell battery phone chargers, which are made for USB mini adapter and will run off rechargable AA's. $10 a year ago, probably cheaper now. I don't drive anywhere without that thing.

so far this is the best deal i can find for batteries and chargers for the g1 - http://cgi.ebay.com/ws/eBayISAPI.dll...2BSI%26otn%3D4

I'm just saying, the device is big as it is. Multiple people that I've shown it to have commented on that. By all means if you can tolerate an extra 4-5mm on the back of the device, go for it. I mean I hate belt clips and cases but I have friends that love them. To each his own you know. I was just commenting on my thoughts about the double thick batteries. If I could get a 2200mah battery for my G1 I'd be absolutely happy with battery life, it would be comparable to my last mobile phone or better.
Also, for the record I don't want to have sex with the iPhone. I love it's industrial design, I think the UI is slick and polished and responsive (moreso in some respects than our phone) and there's a certain elegance to a device you can't really fiddle with but works well out of the box. That said, there's a number of reasons I never bought one. The largest being Apple's proprietary perversion and the extra costs they force on you.
My pockets? I feel the G1 in my front pocket any time it's in there. My last Samsung flip phone was only noticeable when kneeling. I have to take the G1 out whenever I sit down. That annoys me. Making it larger is only going to aggravate those things. Carrying around extra batteries in my pockets is even less practical. What if I forget one and it goes into the wash?
I'm not trying to hate. I'm just saying what my opinion is.

I'm pretty tired of all the people complaining about how thick the g1 is, and how they have to 'take the phone out of their pockets everytime I sit down'...c'mon people, you knew how big the phone was before you bought it, so why complain now? SHUT UP!

To be honest, I may stand corrected on my last statement -- going from 1150 mAh to 2200 mAh is practically impossible without making the battery bigger. If so, they would have to sell you a new back cover to handle the extra thickness

I also stand corrected about being able to run 2 batteries. There simply isn't enough space to lay them out adjacent to each other without interfering with the camera.

Back to square one. I would still kill for a 3600 mAh battery that practically replaces the entire back cover.

Or I could just stick with keeping extra batteries around and gloating at my iPhone-toting friends who run out of juice at the end of the day with no convenient means to recharge

On a very basic level you could use two Li-ion cells in parallel to increase capacity and the cells will charge.

The problems arise when the batteries contain electronics (ie temp sensors and internal charge circuits that communicate with the phone) or when using un-intelligent cells that are at different charge states.

The phone (as far as I am aware) has only 1 charge circuit which if charging two dumb cells would not be able to differentiate between the cells and would not be able to correctly charge them both as they really need to be charged independently.

As the cells internal chemistry changes the disparity between the cells increases and the likely hood of over charging or discharging beyond the recommended maximum of one or other of the cells increases.

Li-ion batteries need to be treated differently than Ni-mh/cad, they don't suffer from memory effect, but they can be killed or have their life shortened fairly easily if over charged or over discharged. That is why the intelligent charge circuits in laptop batteries monitor charge state/temp each of the Li-ion cells within the battery and can switch off the charge to that cell while the other cells continue to charge.

So yes it is possible to charge two cells in parallel, but without being able to charge/monitor each cell individually, not advisable. It may also be possible to include a charge circuit to monitor the individual cells.

You're right. In the end, the simplest solution is the best solution -- carry a spare. It's cheap and it works without drama.

I got this last Monday, and so far I'm happy with it and I can notice the difference.

I charged it for 3 hours on Monday, then I drained out completely, before I charged it again for 6 hours, after that it survived 24 hours and the meter was still reading 40% remaining. I had bluetooth & wifi on all the time. I use a bluetooth headset while driving, and I browsed for a few minutes.

I will continue testing and let you guys know how it goes.

Cheers,
-Gus

Which battery you got? The one from Seido, Fommy, or other?

Seidio, Innocell 1400mAh

-Gus

the best solution is to order a spare battery, you can find one for less than 13 bucks on most sites...
check ebay, there are a few deals on there thats out of this world.

Two things you should avoid buying on Ebay is batteries and memory cards.

Sometimes when you get batteries on Ebay, it's either too old or does not work that well.

Some of the memory cards sold on Ebay are defective or dummys.

htc g1 has only been out for 2 months, and the only other device that shares the same battery is the htc touch pro( not sure about this).
i ordered an extra battery from handhelditems.com and it works fine as a spare battery... ordered the stand alone charger, 2 extra battery combo, screen protector combo for 23 bucks.. cant beat the bargan and the seller has a high rating, and the product has great reviews.. will let you know how it works out, and post pics of it. but i wouldnt but memory card from ebay unless they came in original package. newegg.com is prob the cheapest and most reliable place to get sd cards from.

wow, see my thing is i dont want to buy that battery and a newer/better one releases

I wonder then how did Nokia manage to fit 1500mAh battery into this device that is thinner than even iPhone... Granted it is not touchscreen device but still - look at this profile - and it delivers 10.5hrs of continues talking on GSM, over 5hrs of constantly turned on GPS, etc



My point is - it is possible; it was just ignorance either from HTC or Google to push little bit harder for better battery.

My wallet is fatter than my G1...

Damn do you guys really have that bad of battery life?

Mine lasts me around 20 hours (give/take 2-3 hours)... which is more than enough for me to get home and charge it while sleeping.

There is no need to buy a new battery, call T-Mobile, you have the right to a replacement battery 90 days.

my battery will barely last me all day with light use. With moderate use, I HAVE to charge it in the middle of the day if I want it to last till I go to sleep.

The funny thing is that I called about the battery and the few customer service reps that answer are like they don't want to hear it when I mention the battery issues maybe cause I've called about every week about the poor data connection. I'm in a edge area only and the speed of the edge connection goes from 180kbps to less than 20kbps sometimes for no reason, and I'm in a perfect reception zone and they can't figure out why( I'm on my second g1 and they want to send me a another replacement). So for me its easier than begging for a battery and just buy one that's about 13 bucks even though I found them for 7 bucks with the discount.
The bad part about having replacement or extra batteries is prying off the protective case I have and then the g1 back case.

May I also suggest that you hit the app market and download Power Manager. Set it up to shut down Power mongers like GPS when there is no program calling for it, and you get up to 2 days of "average" use.

So im getting mixed reviews of these "Ebay Combo Packs" i am looking at the one that comes with two batteries and a wall charger. Can someone who has used them give me a good honest review.

does the Seidio Innocell 1400mAh Extended Life Battery need a separate charger or can it be charged with the same g1 phone charger??

Same charger.
I have 3 G1s and 3 Seidio Innocell 1400s right now.
Don't ask

I just orded the Seido 1400 battery. How has it been for you?

I just wanted to bump this in case there's an answer to this question.

The wait for a suitable extended battery for the G1 is finally over. I picked up the $42.95 Innocell 1400mAh battery from Seidio.com and I’m happy to report that the promise of 15% longer battery life seems to be legit. So just be happy to not have to recharge your G1 after every two hours?
Seidio invests in extensive research to find the best and most powerful battery components on the market. They carefully select top quality Japanese cells for our batteries to ensure the highest level of safety, quality, and performance, as batteries are the most essential cellphone accessory. There research, knowledge, and expertise give us the ability to create batteries that provide maximum capacity in their comparable space.
- Made from the highest quality Japanese cells
- Comes with a door in black with Seidio's signature soft touch coating
- Adds only 3-4mm to your device
- Keeps your phone charged and ready to go, even with heavy phone and data usage
- Capacity: 2600mAh

I would definitely buy something like that. I have an Eris, and saw someone's post that said there was an "extended" case that accommodates a larger capacity battery. I just haven't found any place that sells such a thing, much less too many places that even sell replacement batteries for an Eris. I did see one place that sells the replacements for $8.99 for a 1000 mAh and another with a $9.95 1100 mAh. I don't know whether to trust a $10 battery, but having a cheapo in my pocket is beter than timing out in the middle of a game of Jewels.

This sucks. Just because this is my first post the status says I am probably spam! That is just plain BS!
