Subway commuters - battery life tip
OK, this is really not a TIP per se as many of you know it, but as someone who commutes daily in NYC subways (40-60 minutes per trip underground without reception) I was alarmed when I first got the phone and it went from 95% to 75% in just one ride and that's without gaming (only music playing). I tried forcing the 3G mode, but still did not improve much.
So the other day I started using airplane mode in the subway, even with some triplong sessions of gaming underground my battery only drains down to 85,86% from approx 93-95 when i enter the subterranean tunnels. It's a hassle to remember to turn it back on when exiting the trains but i guess every little bit helps.
I don't have mine rooted (yet). It's the factory settings with a bunch of apps installed. i say this confirms the fact the 4G antenna eats up power like crazy when trying to search for an nonexistent signal

Yeah this was a problem for me in nyc subways even before i had a smart phone. Phones just keep searching for a signal the whole ride. The plus side, if you let it search, is you can get signals at penn and grandcentral and a few other places, so you might get your notifications pushed thru.
Airplane mode is a good way to avoid the battery loss tho.

Another thing to try... put your device into Airplane mode, then reboot... after it comes back up it should still be in Airplane mode, but check anyways... then see what your batter life is after your trip... I'll bet it will be better even with the battery it takes to reboot.

You could create several shortcuts to tasks with different time periods and just choose one when you enter the subway station that matches your anticipated trip length.
You can download a 7-day trial of Tasker from their website or buy in the market for about $6.50
(I use Tasker to turn off WiFi when I'm not connected to the cell tower near my house, and to turn my media volume all the way up when my bluetooth headphones connect, and then back down when they disconnect.)
