Get the most from your HTC Sense enabled phone





So you have a shiny new HTC Sense enabled phone (or any other recent Android phone)? Now what? Out of the box, after setting up exchange etc you'll see that the battery life is pretty poor. 

What to do? The #1 thing to do is change the update frequency of your apps. The default for exchange is to update in real time - this absolutely kills the battery. Changing that to 10 or 15 minutes fixes this. Same for twitter, facebook, weather apps etc. Extending the time between updates is the best way to get more up time from your device.

Essential apps? I'm repeating myself somewhat here, but I recommend you get :

  • audio manager 
    • way better than going into settings->Sound & Display
    • Bonus: it is the only way to turn down the phone dialer volume (at least on the Incredible)
  • battery snap
    • great historical graphs of battery usage (how much did watching that video kill it?)
  • realcalc - a sci/eng calculator, even has RPN mode!
  • Listen - for podcasts etc
  • Pandora, or whatever you use for streaming music
  • y5 Battery Saver – remembers wifi spots you connect to, manages waking up wifi, looking for those spots and keeping wifi off when those hotspots aren’t available. 
  • Weather Channel. Disable the HTC sense weather widget (by removing it from your home screen) and get the weather channel's app - it uses less battery, and can monitor more places more intuitively. It also has many more choices for home screen widgets. 
    • Bonus: it has weather maps in motion and you can set alert levels (and the method that alert is signaled) for severe weather.
  • Skyfire - an alternative browser with a neat trick for streaming Flash that the phone doesn't yet support (like comedycentral.com).
  • Traffic! - I know google maps supports traffic, but last I checked it doesn't give very good details on why a place is congested and how long the travel time is through the congestion. This app does that.
  • If you listen to music on the phone - get the Cubed Music Player - visually the best one I've seen. Functionally good too.
  • For the best outlook experience, if you don't mind spending the money, get TouchDown.
Got one to add to this list - put it in the comments!


Update: I just got a travel app called Kayak. This app (and web site) make all the other travel sites I've used (orbitz, travel.yahoo.com etc) look like junk.

Testing HTC Incredible Recharge Cycling Rumors

Rumors in forums state that when the phone is charged just one time, it reaches a full charge that is less than the battery's true potential full charge.

Using Battery Snap I measured battery voltage between charges. I did find that second and third charges increased the apparent charge level in the phone. To do this I followed the procedure:
  1. Charge with phone on until the indicator LED turns green.
  2. Turn the phone off, charge again until the indicator LED turns green again.
  3. Repeat #2.
The only thing I did different was to turn the phone on between each step and look at Battery Snap readings. When I was done, I had Battery Snap export its data (in CSV format) and I created the following graph:


From the data it does appear that the mV level of the battery can reach new highs with this procedure. Even as an electrical engineer, an employee of Qualcomm, and a member of the Snapdragon design team, I don't have a ready explanation for this. Not surprise there, I don't do batteries!
