I initially reviewed the T-Mobile Dash on September 21st, 2007, when I had been using the phone for a little over a month. At that time, I had nothing but praise for the phone, with the following comments about the battery:
I’m impressed with the battery life – with regular use, I can expect to need to recharge every three days or so.
Well, here we are, with a cell phone that has been getting daily use for a year and two months, and its battery is dying. I have to say, I am very disappointed. In contrast, the Motorola Razr V3 that I purchased in February of 2006 has a consistent and high quality battery life, just as the Samsung E315 that I purchased in March of 2005 is still going strong.
The Dash battery life? Not anything to write home about. For the past month I have been putting up with a phone that lasts perhaps 3-4 hours after being charged for up to twelve hours. Needless to say, I’m constantly plugging the phone back in, in my car, in my house, in my mother’s house, etc. I’m taking to traveling with an AC adapter, and have even considered one of those battery-operated adapters (how ironic, using batteries to charge batteries!). Today I purchased a new battery from eBay, and I hope I can go back to having a cell phone battery that lasts more than a few hours.
T-Mobile, I’m quite disappointed. :/

Hello, and welcome to In My Bag! My name is Jenn, and this is my product review blog. In My Bag is where I showcase my reviews of many of the products and services I buy and use, as well as the occasional trials, coupons and freebies that come my way. Interested in learning more? 
I’ve noticed that my cell phone battery life expectancy is directly related to what I’m doing with my phone – if I do a lot of calling, texting, etc – usually within a year my battery won’t stay charged and that’s with any phone I get. My current phone isn’t very old so I haven’t had a chance to run it down yet.
