2 days of usage till full battery drain on my 9900
As a pretty mild to heavy BB user, I decided to test how long the battery could last without plugging it in whatsoever with regular usage (i.e. until it says battery drained and shuts off by itself).
To my surprise, I was able to get two full days out of it. One thing I noticed is when the battery level turns yellow, it still lasted several hours before going to red, and then lasted for a while longer before shutting itself off.
I admit that I jumped the gun in previous weeks of usage by plugging in my BB into the outlet whenever the battery level comes down to 25% (Thinking that it'd die soon). At least now I know that it will go on for a while after hitting the 25% mark.
I've been on the official .439 since it came out.
I'm already pretty vigilant and conservative with battery life, so I fully exit apps I don't use, run wifi-manager, tweak display settings etc...
Just a note, I tried the same test again with all these apps running in the background: Beweather, score mobile, google maps, flixster, Stocks+, BB Traffic, Weather Channel, Poynt (With some of them updating regularly) + regular e-mail and BBM usage, and only got about 16 hours before it drained completely. So it does matter how many apps you leave running ;)
Have we sacrificed function for form?
I too struggle with battery life, in fact I've come to have a routine. I wake up in the morning and turn off 4g(hspa+) I can deal with a slower connection even though I should not have too.
When I can I use the wifi, getting data from wifi is less draining then using 4g for data intense applications like youtube (which I rarely use).
I spend 3 hours a day on the road so I need bluetooth, but always turn it off indoors.
The first month I had this phone I would get a full day easily, the day would end in the yellow. Now my day ends in Red, if I can make it home at all.
Man I love this phone but never had this problem with my old Bold. I never had to touch the 3g and bluetooth stayed on whether I was using it or not. In fact last time I had a car charger was when I was a Windows Mobile Fanboy, but it appears I may need one now.
I've heard that it is better to only fully charge and then fully discharge your battery. As opposed to putting it on the charge when its a bit low for 20 minutes to get a bit more juice. Any thoughts?
