battery of samsung ativ book np880z5e

hey guys, my lap is samsung ativ book np880z5e
when the battery charge full 100%, the laptop use the energy of the battery or the acc adapter ? ( i worry the battery is wear)
serie Dell have a software "Dell Battery Meter"


It's usefull when i plugged in : i want used the energy of adapter, not energy of battery !!
the samsung' software have the same software too ??
in my easy setting don't have "Battery Life Extender" and the bios don't have too !!
i use win7 !!


sorry, my english is'nt good !!
thank for helping ^^

 

Don't worry about it. Modern laptops are more than smart enough to not use the battery when the laptop is fully charged. I always leave my laptop plugged in at home and don't have any issues with it. Li-Ion batteries also don't degrade much when they are fully charged and manufacturers are making sure you get the maximum battery life possible.

You can even simulate this. Plug out your laptop for a few seconds/minutes until your battery level is at 99% and plug it in again. Your laptop won't charge yet, since it's such a small value and is only causing harm. Today I've transported my laptop to my desk at the university when it was in stand-by mode. Currently my charge level is 98% and plugged in, I'm certain that my laptop isn't touching the battery at all at the moment.

The best thing to do for Li-Ion batteries is to charge them as often as you can. They don't like to be discharged and discharging them to 10% causes a lot more damage than let it only discharge to 50% (could even be 10 times more harmful!). So my advice, don't think about it and plug it in when you can.

 

thank u, my laptop is fully charged , i plug out and few minutes later my battery is at 98% , i plug in and the battery is "plugged in, not charging", great
or no when i shut down and restart win, the battery' level is 98%, i plug in and the battery is "
plugged in, charging" ? How about that ??

 

A top-up charge will only be initiated when the charge level drops below a threshold value. This might be 95% or it may be something else. If you want to know what it is then use the computer for a few minutes on battery until the charge level drops by 1% then plug in the PSU and see if charging starts. If not, run for a few more minutes on battery and try again.

As already explained, this behaviour is deliberate to minimise the small top-up charges that cumulatively damage the battery chemistry (as do the full discharges). However, periodic (typically every 6 months) full charging, draining and recharging is needed to recalibrate the battery.

 

Hello @hero99, welcome to NBR.

You may notice I deleted your questions about this in the Owners Lounge thread - both yesterday and today.

Please don't post the same question or subject in multiple threads. It's called cross-posting and is a big no-no on almost all internet forums because it wastes other members' time as they respond to questions that were already answered elsewhere.

If you prefer posting in the Owners Lounge thread, we could move your posts there. But in this case you already received great responses in this thread from @Goldmund and John.

Don't worry, it's a common mistake

 

i try, my laptop is 97%. Can i change this value on bios or control panel ??
thank u !!

 

The value is fixed in the BIOS and not changeable by the user. The previous generation of Samsung notebooks had the battery life extender feature which limited the charge to 80%. However, Samsung dropped this useful feature claiming that the battery technology had improved and it was no longer needed. More likely, in my opinion, is that people didn't realise how it worked and were complaining of short battery operation time. Anyway, don't worry and leave the computer to manage the battery charging. However, if you've had the battery more than a year then it would be advisible to run the battery calibration (it's in the BIOS) so the current capacity can be recalculated.

Silent mode was another trap where Samsung didn't clearly warn that reduced fan operation came at the cost of the CPU being locked down to minimum speed. However, I don't think that Samsung have dropped this feature.

i used that within 2 weeks and the wear level of my laptop incresase 7% to 17.4%. How about that ? it's not good !! (before i used within 1,5 years, my wear level is only increase 7%)

 

Sometimes the low wear rate is because the battery hasn't been calibrated so it thinks it has more capacity than is actually the case. When this happens you will find that as the battery approaches empty then the run time remaining reduces faster than predicted.

i used few day with plugging, the level is drop 100% to 97% ( plugging, not charging), if I continue used with plugging, the level is increase 97% to 100% (plugging, charging) so the battery is charging and discharging many time ->increase the number of cycle ?
so i plugging all the time is good ?

 

I don't think the individual top-up charges individually count as charge cycles but perhaps thirty x 3% = 1 charge cycle.

The threshold for triggering a top-up charge varies with different notebook manufacturers but a 3% drop is typical.

Lithium batteries and the rules for charging them have improved significantly over the past 10 years. The battery for one of my earlier Samsung notebooks (the X60 or X60plus) died soon after the 12 month warranty period ended. We are now having batteries that still retain more then half their charge after three years. However, I don't like tablets and phones where there is no provision for replacing the battery.
