Cool battery life

Hello all! Since I have recieved the froyo update a few days ago, i have noticed a really big difference in battery life. I used to be able to stretch a battery charge for two days. Now, I am lucky to see 12 hours off charge and thats if the phone is idle! Anyone else experiencing this?

You may want to let your phone run until it cuts off by itself, then put it on the charger and leave it, undisturbed, until it reaches full charge. That should (in theory) recalibrate your battery read-y thingies.

I have noticed the same thing with my battery. For me it's the wifi that really kills it. Before the update it was able to have wifi active at home, but now if I leave it on it will drain the battery faster than before. Leaving it off still lets me run the phone for a full day however. I haven't tried letting it run down to die yet however.

I have let my phone go dead to reset. But thats the problem, its not just that the indicator is off, the phone will actually die. I do not use the wifi and always have it turned off.

It may not have anything to do with the battery calibration, but your phone never actually goes dead, if I correctly understand how these things work (feel free to chime in, anyone).

It's really bad for the battery for it to actually die, so your phone tells you before it actually happens and turns itself off before it goes dead dead. If the calibration is off, it will tell you prematurely, and it shuts off earlier than it should. That's if.

The method of calibrating, I learned from Pastafarian, cos he said that's what worked for the Moment. We're only assuming it works the same for the Intercept, but I think it's a correct assumption.

I thought that I was doing this. I ignore prompts to plug the phone in, and allow the phone to turn itself off. I then plug the phone in to charge. How would I do this differently?

No you've got it. I guess I misunderstood what you were saying. So it's still dying fast after doing the kill/recharge thing. I got it now, sorry. That sucks.

The battery stats are located in System>Data and if you delete it after a full charge it will re calibrate if you let it run down. The way I understood it the system stores charging data and determines how dead your battery is off of that. If you recharge frequently android thinks your battery is low based on the time between plug ins.

How do you get to System?

I too am wondering this. I know how to check the battery status, but beyond that I am lost.

I use Root explorer. It is actually under Data/System/batterystats.bin You would delete that file and restart the phone and let it run til it shuts off. Then fully recharge and do that about three times to get an accurate measure of battery life. Avoid to the 20 min charges if you can during the day. If you have it on the charger leave it there unless you have to absolutely take it off. At which point let it run all the way down. I went from 8-10 hours a day on my moment to 14-16 hours. My wife's intercept went from 6-8 causes he syncs everything to about 12-14.

That sounds like an all-around colosal, inconvenient PITA. Here I thought charging regularly was a good thing! LOL

Short charge cycles are great to alwassy feel like you have plenty of battery but it doesn't train the battery management well.
