Accessory Review: Extended Battery w/ Cover for T-Mobile G1

Stock and extended batter angledLet’s face it.  If you had to pick one thing you would change about your T-Mobile G1, its ability to drain your battery within 6 hours of standard use would rank in the top 3.

For a handset as advanced as the G1 it is quite puzzling as to why HTC and T-Mobile decided to skimp on the size of the battery.  Surely their lab tests gave them some indication that this would be a problem right out of the gate.  Perhaps we could overlook this if T-Mobile and HTC were strangers to battery draining devices, but they’d experienced the exact same issue with the T-Mobile Shadow.  T-Mobile did step up and issue the extended battery to anyone that requested it, but that has not been the case with the G1 up to this point.

Fret not my friends, for there is a solution!  The Innocell 2600mAh Extended Battery for T-Mobile G1 by Seidio solves the G1’s battery problem quite nicely.  This extended battery more than doubles the power of the standard battery, supplying your device with the juice it needs to truly run like a “next gen” handset.  The larger battery will require a new back cover for your G1, but this is included in the price and at the time of this review all 3 colors were available to order.  The new back doesn’t have the “with Google” stamp on it, but other than that you can hardly tell the difference.  It even has that same rubbery feel as the original back, and as an added bonus the opening for the camera is recessed providing more protection against finger print smudges.

For the first 3 days I did notice the added weight and girth of the battery and the new back, but after that I eventually forgot about it.  If you’re used to carrying your G1 in a leather case, gel skin, or plastic shell you will almost certainly need to invest in another way to protect your device.  The added thickness will render most protection solutions obsolete.  I did try to use my existing leather case and it actually ripped at the seams!  For now I’m carrying my G1 in my pocket, but a case is definitely in my near future.

Performance is what matters most and the added power was noticeable immediately!  The manufacturer states that it may take a full 5 to 6 charges before you see the total benefit of the battery, but I was impressed after the initial charge.  I went a full day and a half before I had to charge the battery again.  This was with an active Wi Fi connection, Bluetooth, GPS, camera use, and a decent amount of mp3 playback as well.  Had I attempted this on the stock battery I would have had to charge it half way through my day, and that’s just no way to live!

If you want to unlock the true potential of your G1 then I strongly suggest you consider investing in one of these batteries.  It allows you to use all the features of your device when you want without having to wonder if you’re going to be near a power supply at some point in the day.  Free your G1 from the charger and unlock its true potential by investing in this extended batter from Seidio.  My only regret is that it took me so long to order mine!

You can grab one of these batteries out of the AndroidGuys store for $54.99 as of today.  (October 2, 2009)

    I've used this battery since nearly day 1, and while heavier and thicker than a standard battery, its still smaller and lighter than my old MDA.

    Solves the issue of having to look for a charger all the time.

    A G1 must have.

    I've used this exact battery now for about 5 months. I got over the size in a couple days and would never go back to the stock battery. This battery allows you to use the G1 as it should have been all along. I can run it with everything turned on. I can talk on the phone normally. I can surf the net, text, IM … without worrying about the battery. Its great. My work day starts at 8am and my phone goes onto the charger once, at about 10pm each day. By then the battery bar is in the yellow. I now laugh at my buddy who lives at his desk, tethered to his pc by the data/re-charge cable. Sure you can run this battery down if you used the device constantly all day. But when using it normally you'll get a full day out of it ,no prob. I love it.

    There's a major problem here not mentioned, and is something you'd only notice with use.

    The problem is clear by simply looking at the photo of the battery—it sticks out of the phone very far (hence the need for the new battery cover). The problem here is that with the new cover, there is now space underneath the cover on the top and bottom of the phone (below and above the battery), space that has no structural support. If you keep the phone in your pocket and subject the back cover to a lot of stress (e.g. sitting down with the phone in your pocket), the cover will crack in these locations. Be wary.

    I can see one problem for me with this battery. I always use the hard plastic belt clip and this would definitely be too big for it. Otherwise I would buy it. However, I do have the Sedio 1400mAh extended life battery and it provides pretty good performance for not needing the larger cover. I just swap out the battery when needed.

    The camera opening looks weird on that cover. Is that just a hole? I would be afraid to put this in my pocket for fear of never being able to remove it ever again.

    I have that battery, and truthfully, it's to big for my daily use. But I do use it when at conventions or places I know I will be board and surfing all day. Or twittering a big event.

    I have discovered that this battery will only charge to 50-75% full off the USB port. So if you are going out of town for a few days, don't depends on a USB cable and your laptop to charge the battery. Bring the HTC charger.

      I should also say the fit and finish is not the best. I have had the phone turn off in my pocket a few times as the battery to cover space has a bit of slop in it. . The larger battery cover should have something that better holds the battery in place.

  • Alice

    No info on the website – do they charge state sales tax to CA residents? If so, with tax and the shipping charge, that makes this battery way too expensive to bother with.

    I have one of these, it's been working fine for 3 months now. I leave bluetooth and 3G enabled while listening to MP3 on my bluetooth headset for 8-10 hours a day and the battery has never gone below 50% when I get home. The construction quality is great, I have no idea what others are complaining about.
