There is one thing most HTC Dream owners can agree on. Battery life is lacking. An extended battery is an option, but they are so big that they come with a new back plate which makes the G1 as thick as a brick. This is not a viable solution.
With those facts in my mind I went in search of the highest capacity battery out there that would keep my phone the same size. And boy what an adventure!
After searching I online I found a 1600 mAh battery at Fommy. Manufactured by 4U, it seems like Fommy is the only place that sells them. Online, Fommy has a mixed reputation. I found people on various message boards saying their item had been on back order for weeks, while others were pleased with their transaction. I decided to risk my $35 for the possibility of 45% more battery.
A package arrived less than a week later and I was pleasantly surprised. Your mileage may vary; I am less than 300 miles away from Fommy. Instead of the 4U 1600mAh battery I received an unbranded 1700mAh battery! It clearly states on it “Replacement For HTC G1” so I popped it and charged it overnight.
On a typical workday I use my G1 for a couple phone calls, texting, Twitter (like a maniac), a couple emails a day, and a handful of quick fact checks on the internet. In general I like to keep everything on except for Bluetooth. I do use Locale to try to manage my settings, but that’s. I love Locale but seriously it has become overly complicated for what should be essentially a series of IF THEN ELSE conditionals. To put it politely, an inexact science.
With the stock battery (1150 mAh) I would need a “top-off” after my lunch break and on the drive home in order to make it through the day, even after Cupcake. With this new battery there is an obvious improvement. I still can’t make it the entire day without a “top-off” but I’m definitely not in a desperate search for the charger. I have found my commute from work is long enough to give me enough juice for the rest of the night.
Now, this whole review could be a waste. I have contacted Fommy and they said I received the 1700 mAh battery because the 1600 mAh battery was out of stock. This is probably in response to the many message board posts complaining of their Fommy orders being on back order for weeks. They were unable to answer my question of who manufactures the 1700 mAh battery and if they have plans to sell the 1700 mAh battery any time soon(although judging from my results they should). That said I can only assume the 1600 mAh battery would provide significant improvements over the stock G1 battery as well. In either case I think it is well worth the forty dollars to have a battery that will last you all or most of the day.
