Extend Battery Life
I have heard several people complain about shorter battery life since the Froyo update. I am suspicious this has to do with the faster processor speed. With everything in life it is a give and take. Slightly better performance for shorter lived performance. LOL
So what can you do?
If you are rooted, download
setCPU. Set up profiles to lower the CPU speed at times when you are less likely to need the speed (like when the screen is off). Set it to limit the CPU speed when your battery reaches a certain level. etc.
Rooted or not, try
JuiceDefender. The drawback to this app, it turns your data signal completely off and on automatically. So you may not receive a SMS, MMS, or email message for a delayed amount of time. There are tons of settings to match your needs though. Give it a try, it seems to significantly extend my battery life.
Again, if you are rooted, try
Autokiller. This is MUCH better than any task killer out there, as this app uses the native memory management system built into the Droid OS. The typical task killers are not good to use (plenty of info out there on this). This app will help keep your phone running smoothly. I recommend starting at a lower setting and slowly working to a higher setting till you find which works best for you. Idealy, you want it as low as possible with out signs of bogging down.
Good luck and I hope these tips help everyone out there experiencing short battery lives.
