Evo's battery life is quite good, if you know what the problem is.

---

So my wife and I both have Evo's. Both of them running DamageControl's ROM. My battery life will be down to about 45% (or less) after about 4-7 hours. Hers will be between 94-97%. This is with not really using the phone except to answer a call or two. Everything is turned on, WiFi, GPS, Bluetooth, Sync, GPS location, etc. All the social and Sprint apps have been removed except for Sprint Navigation. No CPU controlling tools are running, such as SetCPU or OverclockWidget. Though Advanced Task Manager was running in the background to kills apps every 30 minutes, but I don't think that had much of a bearing on it.

At first I though my battery was defective. It was nuts that her phone was lasting so long and mine was being sucked dry. She wouldn't let me take the battery out of her phone to test, so I started looking at what the differences are between our phones. The only main difference between our phones is the number of apps installed.

So based on that guess, I used Titanium Backup to backup all my apps, then proceeded to remove just about all the apps on my phone. Especially any app that might use the network. Though I left wireless tether as that was installed on her phone as well.

I charged up the phone to 100%, left it unplugged overnight, and after seven hours, it still had 98% charge left. So it was an app(s) that ended up killing my battery life. Now I'm using Titanium Backup to start restoring a few apps at a time until I can find out which apps that are causing the large battery drain.

Very good read. I'll be trying this out as well.

Like Google said at their I/O conference, "if you can't get a day out of your android device then something is wrong with it".

Wow - sounds like a great experiment. Eagerly awaiting your findings.

There's an app called Systempanel. Even the free version will tell you in an instant how much cpu each running process has been using since it was loaded into memory.
I also use it as a task manager. Since it doesn't need to be running in the background like some other popular task managers.

Added back about 60% of my apps and still have excellent battery life. Only lost 3% over last night while sleeping. I mostly concentrated on adding back apps that shouldn't access the network. I'll start adding a few apps back that might access the network and let you know the results.

My battery last over 30 hours.

Here's the proof. I also had 50% battery left.

can you let us know what apps you're running and what was re-installed and what has been re-installed as yet.

One thing that EVERYONE should do before they even begin to evaluate their battery performance is CALIBRATE THEIR BATTERY!!

Can't stress it enough, it's crucial.


And fwiw I've found beautiful widgets to be a battery hog whether you're using it or not
