95% battery
 

My N900 is fully charged(green led light), but when I check it using queen beecon, it says 95% only. Is this normal?:confused:

Re: 95% battery
 

yes, the battery doesn't charge to 100% for several reasons. Look it up.

sorry about that..

Re: 95% battery
 

i got 97% once...but now back to 95%...damned

It's just the battery meter being stupid..

5-10% variation from charge to charge with idle phone is also normal, depends how recently the phone topped up the battery after reaching full and switching off charger.

does the charger have any logic in it?
would never turning the charger off make any difference?
would using the charger from an n86 or n97 or using the old round style to micro usb converter make any difference?

Re: 95% battery
 

Yes, the charger chip on n900 handles the charge and re-charge itself.
The thing you plug into your N900 is just a powersupply.
It's debatable whether the battery meter has any logic in it.

It would wear out your battery faster.

No. The thing you plug into the phone is just a powersupply. It has no logic in it.

What most battery meters usually do is show 100% when you unplug, regardless of the current true state of charge as long as it isn't wildly incorrect. I guess they forgot that part.

there are 2 types of charge : low and high current
li-ion battery charging type is " voltage limit "
so low current charging type will put more power in battery because high current charging type will heat the battery and the voltage will be higher than an cold battery and charger logic will detect " end of charge " ( ~ 4.195 V ) sooner

inside n900 is a smart carger

The charger does CC/CV to 4.2V with termination when current has dropped to approx 50mA. I say approx, because system load has an impact on what the real termination current will be at.
