Help ICS very poor battery

[pagdodd]

Just a quickie

anyone else experiencing REALLY poor battery life since ICS update?

I don't get a full day out of it.

Yesterday, the phone was switched OFF for around 8 hours and it still didn't last the evening.

I haven't done a hard reset yet, purely because I don't want to lose game saves etc...

The update may have wiped out batterystats.bin thus uncalibrating the battery. Try this (once):

1. Run the battery down to zero and ignore all the warnings. Let it go until the phone shuts itself off. *** This is hard on the battery -- only do it once! *** This will help Android find the bottom of the battery's voltage.

2. Charge the phone back to 100%. Once at 100%, remove the USB cable, shut the phone down, remove and replace the battery.

3. With the phone *still off* plug in the USB cable and charge it until the orange light turns green. Once green, pull the USB cable and repeat once or twice to ensure that the battery is charged to the max.

4. Restart the phone. Now Android has the top end voltage of the battery.

Even so, it normally takes Android a week or two to build batterystats.bin for optimal battery life, so be patient--it will come back.

Hope this helps!

thank you for the informative advice

I have seen this before when I had my original Desire.

It worked for that, so it was going to be my next option before wiping.

Will give it a try at the weekend.
