Honestly...I think bad battery drain from a weak signal is a little over exaggerated.
I'm in a low signal at home all the time and still get stellar battery life. But yes...I am sure it drains a bit faster....But only a bit.
And aside from information, those signal booster apps aren't necessary. They just find the strongest signal...temporarily. so you'd have to run before any call....and don't move an inch, or it may jump right to another tower again.
The exact same can be accomplished by toggling airplane mode on and off.
But still....some have good info...I used this one before too...on my s2...which would only work if I went outside my house. Haven't had that issue on my Moto x...signal is fine inside. The radio blows away my s2.
