Battery not full after charging

[Guest energylove]

Hi All,

Sometimes my Desire behaves strange:

I am charging it for the whole night and it has a green led. In the morning, I am unplug it from the charger use it for one minute. Immediately after that the battery gauge drops to 90-95%.

I charge it again for several minutes and the gauge go up to 100%. After that (and for the whole day), the gauge go down very slowly (even with heavy use).

I tried to calibrate the battery but with no change.

Thanks

Have you tried the wipe battery stat option in AmonRa?

A gui with a oc kernel have a solution i think..flash the new kernel from here and see if it help....he write...that reload after 99%

Thanks.

I tried to wipe battery stat - not help.

I saw the tread.

Do you know a solution without overclocking?

its normal with 998 mhz...only if you set it higher with set cpu..you get the 1113 mhz

Just to say, I'm experiencing the exact same behaviour. I have tried the various battery conditioning techniques including the wipe stat but it still occurs regularly (but unpredictably).

Same here. But I've noticed that if you turn Wi-Fi and Mobile data off

while charging, battery status shows 100%.

Have you tried a new battery? :P

Given that the problem is intermittent and the battery that came with the phone would be around 4 months old, I'd be surprised if that were the case?

it's absolutely normal behaviour. install JuicePlotter (free app) and see how the battery voltage changes. usually it charges all the way to the 100%, then waits for a couple hours, then drops the voltage to about 92-95% and starts conditioning battery, recharging back to 100% for another 30-40 minutes.

so, there's about 25-30% probability you unplug the phone while this conditioning process takes place, hence the small drop in the voltage.

The Fix Richard applied had the averse effect on GSM Desire's.

I'm now checking V5 of that kernel to see if it is gone, but at first sight it's still there.

It's what Alex already was referring to.

Richard trips intent in v4 of Desire Sense UVOC Kernel was to set the device to discharge to 99% and then recharge again, instead of dropping to 95/3% and then recharge.

But the effect was that it brought back the "Charged to 100%, remove from Charge and it drops to 90%".

Which was gone on last r9 WIP.

I will do a Calibrate again today to be sure.

Thanks lenik, haven't experienced that on any other phone (that I am aware of) so was unaware it would even be taking place. Awkward though as once it's gone into conditioning mode and you unplug, the battery life does appear to degrade throughout the day much quicker.
