If you've read previous posts, you know that I'm currently
using the HTC Thunderbolt 4G Android device. You can
read some the pros and cons
here. One of the main cons of the TBolt was how quickly
the battery drains when the phone is set to 4G. I quickly
learned some things I could do to
preserve battery life,
including figuring out how to
switch from 4G to 3G because HTC forgot to include a
toggle in the Thunderbolt.
So, most of the time I have my phone in 3G
mode and for the most part it works amazingly well. I switch on
4G only when I want to watch streaming video or for downloading
apps and programs.
But, as with any Smartphone, if you want to stay really
connected you have to deal with the issue of much shorter
battery life. Sure, you can purchase an extended-life battery,
but most of them are manufactured by after-market companies and
the bulk of the reviews I've read is that they don't perform
much, if any, better than the OEM shorter-life batteries.
Enter the JuiceDefender app. This free Android app (with pay
versions if you're so inclined) claims to dramatically extend
your smartphone battery life by managing your mobile date, wi-fi
and CPU speed.
It's very easy to set up in the default mode. Just follow these

Now, the standard settings recommended by JuiceDefender Battery
Saver will control your battery life and give you noticably
extended periods between charging. Or so they claim.
Does it work? From my experience, absolutely. The biggest thing
that I can see that it does (because I already make sure my GPS,
Bluetooth, etc. is off unless I need it), is it disconnects you
from the 3G or 4G network when you put it in standby mode,
periodically connecting to grab anything that may be out there
looking for you. When you take your phone out of standby it
automatically reconnects you to the network and you move on with
your cyber life. From the app's onboard calculation I'm getting
almost twice the battery life than before. From my perception,
that seems about right.
My only complaint so far, is that when your phone is idle and
then you grab it and power it out of standby, it sometimes
(usually it's quick and seamless) takes a little while for it to
reconnect to the 3G or 4G network. Usually it reconnects in two
to five seconds, but I have had a couple of incidents where it
took well over a minute to reconnect in an area that has
That being said, would I recommend this app? Yes. Even if you
have to wait a minute or two to connect to the network, it's a
much shorter time than if you discover that your battery went
