Easiest way i found to calibrate my battery

[shimoda]

In my case after wiping battery stats happened something strange... The battery remains a lot of time at 100% then descends progressively and sometimes fast... When reaching 40% descends almost instantly and finally deads...

I deleted battery stats again and the situation is very similar...

Any ideas?

-. Charge to 100%.
-. Calibrate wiping battery stats (use any method).
-. Use your phone until the battery is dead.
-. Take out the battery from the phone for about 5 minutes, put it back and try to turn it on. If the phone turns on wait until the battery is real dead.
-. After the battery is real dead charge the phone from the wall for about 6 or 8 hours (maybe while your are sleeping).
-. Turn on the phone and please report if it works!!!!

BTW, don't use HP kernel it has a ugly bug with a kernel process named "ksoftirqd" that eats your battery, it is a shame because this kernel is the best multitasking performance that i've tried on froyo.

thanks a lot mpjoe2000, I'll try this process and repost here if worked for me...
I wipe battery stats from "recovery mode"... I don't know if it's important or not...

AFAIK, it should work any wiping method.

I was discharging the phone to try your method and magically the stats continued descending and the battery died at 3%.

Then I did all your process and the results were very similar... A little freeze at 100% but also died at 3%. It's not perfect (not seems continuous at all) but it's completely usable. The percentage is a good reference now for me. I'll not touch anything more if continues working like this 2 tests.

The battery has 9-10 months, maybe starts to fault a little...

thanks a lot!

Hi guys! I know it is almost Christmas, but I have a battery problem. This happens for the first time with my phone and I don't know what triggered it. My phone is 13-14 months old (if this matters). After I 'd experienced some problems with froyo2.2 + yonip (latest .32 final rev) I've flashed to stock 2.1. Had it for 1 week with NO lags, problems and so, but I wanted to have root + recovery + better theme + multitouch and I've flashed to Ultimate Spicaclair 2.0. After that flash my battery in the status bar 100% and in a widget and in Android System Info app showed 100%. But when in came below 100%, for example at 75% in the status bar all applications and widgets are showing me, that the battery is 78%. When the status bar showed 0% my apps and widget were showing 4%. I've tried wiping battery, charging completely, but nothing changed.

How can I fix it? Isn't it dangerous to wipe again the battery cache (for 2 days I've done it twice after 100% charge)? I will try today to re-flash the Ultimate Spicaclair 2.0, but before using it I'd never experienced such battery issues. That's why I don't know how to fix them..

Merry X-Mas to all of you! Thanks to all of you for the support you're are giving us here!
