Spica battery driver with 1% step

[cenculko]

how to install?

Lithium Ion batteries are supplied with a security circuit board that measures temperature, voltage etc. In case of a dangerous situation it "shuts down" the Battery. Also if you shortcut it nothing happens. Only if that board is damaged it can become dangerous or if there is not such a board installed on the battery.
Thats also the reason why you cant buy raw lithium ion cells.

Cheap china batterys are sometimes missing this circuit to make them even cheaper

This 2 drivers has different full-charge levels. Try to charge your phone while Android is running. When it'll say that battery is full, power off your phone. Baterry will keep charging for about 30-60 minutes to a higher level.

I think the reason is that while the phone is powered on, the measurements are influenced by
the increased temperature and load. So they maybe decided to use safer values.
Why did you increase the lower voltages ?

#define BATT_LOW 180 /* 3.6566V default: 43 */ //112 /* 3.763V */
#define BATT_CRITICAL 130 /* 3.6037V default: 8 */ //(74) /* 3.707V */
#define BATT_MINIMUM (20) /* 3.554V default: -28 */ //(38) /* 3.655V */
#define BATT_OFF (-128) /* 3.4029V default: -128 */ //(-103) /* 3.45V */

Doesn't this give a low bat warning earlier ?

antibyte pls include it in FE!!

Eprom driver charges the battery to ~4,14-4,15V. Original android full-charge voltage is much lower...

I get 4,17 V with this driver. Battery gets warm but in a normal range.
Will try to reduce it a little bit to ~4.14 V to increase the safety buffer.

Can you please include a version without:

Higher full charge voltage (same as for powered-off phone driver)

Thanks for your work.

i think that is part of making the battery status more linear. like 90%bat takes 2 hrs to 85% while 20%bat takes 30 mins or less to 15%. which makes it hard for users to estimate battery life left. this mod will warn us earlier and inform us of battery time left relative to the whole battery runtime.

i guess

Bingo

how can we apply it?

Qbanin, could you readjust you driver to charge only a bit more than the original did ?
I checked the voltage now as the battery monitor app showed 4,4V while it always showed
4,3. The real voltage was 4,18 V and it was still charging
I would feel better if this keeps <= 4,15 V before i include it into a kernel.
Maximum allowable overvoltage is only 0,05 V until damage or worse can happen.
I just think it's better to be a bit extra paranoid in this case
