This battery turned my G1 phone from a trendy cute phone into functional beast. When I first got the phone I found myself charging the battery twice a day. It always seemed to have a low battery whenever I really needed it,

so I bought this battery. Yes the phone is bigger, the rubber skin doesn't fit it and it doesn't fit into my belt case anymore,

but damn it!! This battery never dies. I find myself using the phone to its fullest potential everyday, GPS, Bluetooth, WIFI, surfing the net, making and receiving calls, letting my son use it as a gameboy during long car rides, and at the end of the day, it's still half charged.

I can't overstate how much I use this phone on a daily bases.

It's nice to have a battery that allows the phone to keep up.

I was a little skeptical buying this extended life battery for my G1 because I really didn't want to have to put a new back on the phone and make it even bigger, but after reading the other reviewer's review who stated that the soft back actually made gripping the phone much better while texting I thought I'd give it a try. They are so right, even though my G1 is now about 1/4 larger I am now on my 3rd day of not having to recharge my phone and I still have over 50% power, which is amazing given I was having to recharge the phone once to twice a day, especially when you are using multiple functions. The new back is softer and feels much more durable than the original back that came with the phone, holding it feels much more secure and it will still fit my belt clip case securely without a struggle to get the phone into or out of the case! I'm more than impressed and satisfied with my purchase. I've heard from a friend of mine the other extended battery that doesn't require you to change the back of the phone is good as well, but if you want more than TRIPLE the battery life you have with the original battery and don't mind making the phone a little larger (no visable hump with this new back, either!) I highly recommend it.

I bought a G1 because I have a lot to do. Unfortunately, despite (or perhaps because of) the G1's amazing capabilities, battery life was a major issue. Using 3G, GPS or WiFi severely drained the battery in record time. I also text a lot, as well as post to blogs, share pictures, and staye logged into IM services, Facebook and Twitter.

Enter the Seidio Innocell 2600. At first I was dubious because 3rd party accessories aren't always reliable. I had a week-long trip coming up, and definitely wanted to know my phone would be able to keep up, so I took a chance, and I was very glad I did. It arrived quickly, and was more than 50% charged on arrival. In a short time I had it fully charged and gave it a test run. I turned everything on: Wifi, Bluetooth, GPS, etc. I had all my IM and social-networking apps running and was texting, listening to music and browsing the web. Surprisingly it kept going for over 6 hours, even with everything going. I gave it two full deplete/charge cycles and from there it just got better.

Initially I was concerned about the increased size with the new back-cover, but after using it, I find that it actually feels even better. I like the non-slip feel of the new cover, and the recessed opening for the camera actually keeps the lens cleaner and fingerprint free! I didn't buy this phone for looks, I bought it for power, and this battery gives it that. It's still pocketable, and feels solid. People who see this phone love it, and the size hasn't made anyone sneer or criticize. When they hear I get upward of 8 hours of soli use per charge then rethink their decision to buy that *other* smart phone that doesn't have a swappable battery.

My best testimonial is that I recently spent over 12 hours in delays in Tulsa and O'Hare airports.

I bought my G1 on the day it came out. I love the phone, but I HATE the battery life. I looked and looked for an extended battery for months, before this battery became available. Now instead of the battery ying in about 4 hours of heavy use, wifi, internet crusing, and downloading etc, I get 2 to 3 days of battery life. This battery is a little thicker than the standerd, but to be honest it made it easier to holdont while I text. A must for all power g1 users.

I received this battery yesterday. Last night before I went to bed, I turned off the phone, removed the original battery and replaced it with this one. I charged the phone, while off, overnight giddy with anticipation that I'd have a full battery for days (based on the capacity of the battery and reviews I've read).

Well, this morning I powered on my phone and was distressed to see it was only at 32% charge. I trolled through my power profiler and watched the level drop before my eyes: 32 to 26. Thirty seconds later, it's at 24. This is with the A/C charger *plugged in*. If anyone out there knows what gives I'm all ears.

Rated 2 stars since I'm giving it an extra star on the off chance it's user error. But so far I give this battery a giant fail.

Yes, the battery and the new case make the phone fatter.
But for a tall guy with big hands, it feels MUCH better in my hands. When I switch back to the original battery/case it feels too thin. But that's a personal preference.

The battery, on the other hand, is exactly what I was hoping for. It lasts well over 24 hours with GPS and WiFi and CL and Bluetooth turned on, with higher-than-average usage (tested particularly with GPS). If you don't have any of those settings on, the battery life stays at 100% for about 4 hours before it moves at all (using an app to see more detailed battery status).

The case is just slightly less-than-perfect compared to the original case, but fits just right. The volume controls flush with the case, but are still easy to find and press in the dark.

Also, the case is very strong. I sanded the case down, spray painted it red, applied a logo, and applied several clear coats. It looks professional, and it was a breeze to modify.

The camera is recessed into the case, which actually provides a little bit of a "shade" for the lens, making it better at taking pictures in total sunlight.

The speaker holes are not flush to the phone, and you lose a little volume, but at least you can listen to hours and hours more music/video with the battery life. The phone has a much more noticeable vibration function now, which I like, but you might not.

So, yes, the case does make the phone bigger, but I like it that way and even if I didn't, it's worth it for the battery life when I need it to last all day with all the features, like using GPS and the camera when at a concert all day.
