Optimised and not so optimised charging |

I have T630, when you plug it in it says optimised charging I let it charge till only that last little slivver was left on the indicator so I though I'd hurry up the process and I turned off the phone, so now charging isn't optimised?? When it was turned off it started charging from the middle of the indicator, but I thought it was almost finished. So after quite a while the red LED finally goes off and the battery is fully charged, correct?? I unplug the charger and plug it in again the screen lights up and says charging AGAIN, I know the screen does drain power from the battery but two seconds worth shouldn't mean 10 more minutes of charging?? When it kindly finished I unplugged it and replugged it again and it said charging again????????? How on earth am I supposed to know when the battery is fully charged??????????????? |

Dont worry about it too much my dads T68i does this and all he does is let it charge fully unplug then plug in again for another 10mins and it lasts about the same as quoted so id do that mate |

What is the difference between Optimised and Non-Optimised Charging?

I think.. that with older phones, the phone has instructions to 'stop' accepting charge, and this only works when the phone is on. I think that's why the K700i 'turns on' when you charge it.
But I might be wrong.

SE or Ericsson then said optimised charging is the charging process in which your battery is charged at the right pace and charging stopped automatically soon as the battery is full. According to them, this is only guaranteed when you use original SE chargers; with non-SE chargers, charging is non-optimized :)

well, that might not be such a big issue. with my brand new p910, i had the curiosity to check the status once it finished charging. it said 95%. i let it for another 30 mins and finally showed 100% ALTHOUGH THE CHARGING INDICATOR HADN'T BEEN MOVING ANY MORE!!! so i guess it's their habit to continue charging even after the indicator is full and stops moving.

The charging process is a fairly black art controlled by a circuit within the phone. The fully charged indication can occur at anytime above 90 ish % capacity. As the batt reaches full, the rate of charge slows and the phone assumes the batt is full and charging slows to a trickle. By re-starting the charge process the fast charging occurs again. Provided you use original batteries and chargers, you cannot damage the battery. Things get interesting when you build your own, but thats another story... |

Yes but esato's the best place for that other story, are you saying you build your own chargers? |

Yes, for charging model car packs. Made a bit of an error on the first one I made, and it charged the pack at over 10A. Everything got a bit warm, and the charger melted it's self b4 the fuse popped. I wouldn't suggest anyone uses a non-standard charger on a phone though, since a damaged battery may explode.

my old t300 doesn't even say optimised charging anymore, it just lies there as if a charger hasn't been connected, so after about 2-3 hours I reboot it, and the charge is full   The batt indicator doesn't pass all the stages (green-yellow-red) It just goes from green to white after like 3-4 days 
great phone I have here!!!

My understanding of non-optimsed is that it doesn't increase the battery % it just maintain.
USB charging do non-optimised, so when using you phone usb e.g. as a modem you don't run out of battery but doesn't necessary charge the phone. |

I don't think that is it as you can use usb to charge your phone to max. It's about the charger I think. |

I've wondered about this.. supposed feature myself.
And I find the discription given by ericsson themselvs regarding the feature quite peculiar having noticed a few things;
[quote]SE or Ericsson then said optimised charging is the charging process in which your battery is charged at the right pace and charging stopped automatically soon as the battery is full.[endquote]
I use a retail USB cable for my k310i and I always get optimized charging!
What makes me dislike this medium however is that its using USB power to charge! - the usb port exudes 6v / 12v.
The battery problems phones have nowadays are rooted with their chargers. Without going into the technicalities....
SOOO many providers issue "fast travel chargers", which have higher VOLTAGES, but lower current. This will yeild a FASTER charge time, BUT, less usage (standy/call) from the battery!.
The ORIGINAL chargers, use LESS voltage, and suitable current. This will see them taking LONGER to charge, but the batter will support the phone for LONGER, AND, will live longer over the years. - the former mentioned also reduces battery cycles.
my Issue:
I've found that charging with the USB cable - sees my battery lasting significantly less (TRIED< PROVEN).
That short article above about the bar showing full when Bat % = 90+ is also quite true.
I've started using a lil 12v batt (believe it or not, 12v) to drain my bat to NOTHING after every battery death, before charging. It helps

Usb cable cannot charge your phone as the regular charger does. The USB ports have lower voltage and the electicity is not that good as the one of the charger. So I wouldn't recommend charging the phone on the PC always.
USB charging is good to help you in life or death situation.. When you are in desperate need of energy to power up your phone battery. For everyday life usage, the charger is unreplaceable imho.
