Guys, just checking, do all of you wait till your 'empty battery alarm' comes on before you charge your battery or do you just charge when it's still, say, half full?
Also, how long is a safe charging time? 3hrs? 4hrs? I usually use an auto timer that switches off the charger after certain number of hours to avoid overcharging the battery 'coz I always charge my battery over nite. |

9 DAYS!!!! Wow!!! How did you do that? Is it the normal extra slim battery (flat with phone's back surface)? Do you switch off at nite? Mine gives me around 4+ days before it dies. On average my phone is switched on about 15+hrs per day(I switch off at nite), so only about 60 actual hours. 9 days......wow....  |

did the same thing too...wait till the phone "dies" and changed to my spare battery...as for the charging, well I think its pretty safe to leave it over night as Ericsson has this "smart charging" for thier phones, but for me I'd rather have 2 batteries and a desktop charger. Had a bad experience last time with my T-28s. Burnt my "board" 3 times due to "overcharging" I guess or maybe I'm just plain unlucky !!!!....  |

Nizzy, since you're in Malaysia, may I know how much and where did you get your spare battery and desktop charger? I have a feeling that the original accessories are gonna be expensive huh? So, have you got your phone upgraded to the R4A at amcorp yet? |

bought my phone and the spare batt. at Amcorp Mall (Ericserv). The additional batt. cost me RM80.00 (they gave me a discount) and make sure it's BUS-11 as they might give you the old BUS-10 (this is for T-28s). I didn't manage to upgrade my software yet, still got the old ones R3B006...I think it is safer to buy things from Ericserv or Telemas as they are the official dealer for Ericsson here, had a bad experience with these "underwater"/"local" batt., phones.... |

I think draining your Li-ion battery to empty before charging is not good. I charge mine when the indicator says "low-batt" |

Aren't li-ion batteries free from memory effects? Do we really have to charge them only when they become empty? |

Daniel,
Just came back from Ericserv, sent my phone for repair again!...anyway just confirmed the price for the Batt., it's RM80.00. As for the Desktop Charger I think it shouldn't cost you more than RM 100.00. Anyway you can always asked for a discount.....
I've told them to upgrade my phone to a new software. |

Nizzy, what's wrong with your phone that you have to send it in for repair? Thanx for asking about the battery price for me. I think RM80 is too steep for an extra battery lah. I'll live with one! 
This morning after charging it full, I got about 239Hrs stdby, but found that it actually fluctuates with the "environment" where the phone is at. At certain places, it drops to less 200hrs then goes up again. High tech auto estimation feature maybe? |

Usefull stuff for everyone I guess
CAN I RECHARGE MY BATTERY BEFORE IT IS COMPLETELY FLAT?
Ensure you discharge your battery completely every time you charge it. Many batteries have what is called a 'memory effect'. This means the battery develops memory and it will discharge only to the level at which the battery was last charged. If a battery is charged while it has capacity, the 'memory effect' will develop at that level, even if there is power. Consequently the battery will shut down before it has used all of its power; the outcome is reduced talk time which means poor performance.
[NOTE: This 'memory' thing had been an issue of the past. Now the latest phones (including T68) come out with smart phones which use lithium ion dont have this problem. The memory used to come from powder chemicals inside the battery which never got the chance to be recharged regularly and so got solidified. I have been told that draining the info-lithium ion battery completely is not good unlike the previous 'memory' type batteries]
A battery charger/discharger will overcome the 'memory effect' because it discharges capacity still in the battery, before it begins to charge. Other smart battery chargers have a light indicator which indicates full charge. Because heat can actually drain the power from a battery, remember to remove the battery from these kinds of chargers when they are fully charged. If your battery feels hot to touch when it is recharging, remove it immediately and leave it to cool a while.
[NOTE: Again the modern chargers and phones come with an automatic cut-off when the mobile is completely charged or either of the instruments get overheated.]
HOW CAN I GET THE MOST OUT OF MY BATTERY?
Observing a few simple tips will help to extend the life of your battery and its performance. There are three types of cellphone batteries; Nickel-cadmium, Nickel-metal hydride and Lithium Ion. A Nickel-cadmium battery is the basic battery and the most inexpensive to purchase.
A Lithium ion battery will cost more, but it offers greater benefits; it is half the weight of an average battery yet provides double the talk time. Unfortunately due to a world wide shortage of Lithium, these batteries are currently in short supply.
New batteries always require charging. Charge your new battery, then fully discharge it, at least twice so it can reach its full capacity. You can discharge most batteries by unplugging the adaptor and leaving the battery in it for a few hours. Follow your cellphone manufacturers battery recommendations to ensure your cellphone gives you its best performance.
HOW DO I CLEAN THE CONTACTS ON MY BATTERY & CHARGER?
Dirty contacts on the battery or charger can contribute to charging problems. Use a cotton bud and some white spirits to clean the contacts.
HOW LONG DO THE BATTERIES LAST
This depends on the type of phone you choose. Most phones offer several hours of 'talktime' - the amount of time for which you can talk on the phone before the battery runs out - and a larger amount of 'standby' time, which is time during which your phone is switched on and waiting to receive calls. For details of individual phones and their battery life, check out the Mobile Phone Gallery.
WILL I HAVE TO REPLACE MY MOBILE PHONE BATTERY?
Even with the best possible care mobile phone batteries will eventually need replacing. Rapid deterioration in performance, over just a few days, is usually an indication that battery life is nearing an end. Call your nearest Telecom BusinessDirections store or your service provider for advice on the condition of your battery.
ps: This is some information that I found on the net... and so I thought I would share it with you all The notes in between are my comments! |
