How battery care works?

Any one know how battery care works? Is it really useful?

 

It effectively keeps the battery 50% or 80% charged. By limiting the max charge, the thought is that it keeps the maximum charge potential of the battery longer.

That said, I used it about half of the time on my 1st gen Z. After about 1.5 years, the battery charges to 97% of its full capacity.

If you mostly use the laptop with the AC adapter attached, it is probably a good idea. When you travel or need longer run time, turn it off and charge to 100% to get max battery life.

 

So does this really help the battery life longer? (Life means charging capacity)

Also, if i use this way of protecting the battery do I still need calibration after 30 charge? Because when using sony battery care it's full charge is either 80 or 50%.

 

That's what I usually do on mine.Nonetheless after 6 month my battery already got a 1.5 ./. wear

 

Sorry i'm a noob lol, what's a 1.5 wear? Does that mean your battery only charges and is usable for only 1.5 hours?

Thanks

 

Was that with the 50% or the 80% setting?

 

No.I get 9:35Hrs of battery life >> BatteryCare set 80 ./.
The battery wear is 1.5 percent of 62.640mWh
It means that there is some degradation of the battery.

 

Check the setting within the VAIO Control Center. They explain it pretty succinctly.

 

Oh, I meant the result that you got with your 1st gen Z. You mentioned that after 1.5 years the battery still charged up to 97% of its original capacity, so I was wondering whether you used the 50% or 80% setting. Sorry if my previous post wasn't clear

 

I did 80%. 50% is silly, IMO

 

Well, 2 years of heavy battery use and I'm at 9,9% wear at the moment - it did nothing and then jumped...

Anyway - I used 80% on my SZ.

50% is meant for home use where you only travel from socket to socket.

 

I am not sure your guys how to do it. I am asking this question because I set up battery care at 80% but after 10 months usage, I have 1.5 hours battery life only. How to get more time like your guys do?
please advise.
BTW, how to calibrate battery?

 

Check your battery wear first... if its worn out then that's it you wont get a lot back by calibrating it.

Calibration: Empty completely and charge again.

 

I will calibrate it today to see how, must drain to 0% or 10% as low battery set up?
but noe sure how to check the battery wear? anyone can advise?

 

Download BatteryBar the free one will tell you.

TO callibrate - drain it down to zero.

 

Did calibration today, it is drained to 2% after that the system shutdown automaticly. Is it ok?
Installed batterybar today and the system show me that :
1. battery wear is 3% of 59500mwh
2. full life time is 2:07 means 2 hours only?
What kind of reading your guys can get install the batterybar?

 

Depending on how you use your laptop - ...
If you use "high performance"... call the firing squad (don't)

You should use "Vaio Optimized" or "Balanced" all the time - 2 hours would then sound about right comparing it to my SZ.
There is also a battery saver mode which does just that - using the Vaio Battery Saver + I can get about 4 hours out of it with 10% wear after 2 years.

And wear... it depends on many factos... age... use... my batter is used nearly daily... 10% is pretty good looking at what it has been through so far.

 

I am using Z and Win 7 pro x64.
and using power saver mode for presenation normally.
And discharging rate is 26000-29000mw, is it normal?

 

I'm on an SZ... but it sounds high to me... on my Vaio's battery saver I can drop it below 10W...

On my "Vaio Optimized" mode I do use more than 20W...

 

thanks DetlevCM
any guys here using Z series and batterybar? can share the discharging rate?
Like to see if my notebook is abnomal.

 

That is not normal unless you have discrete graphics on and screen brightness maxed, etc. On convervative settins you should see less than half that discharge rate.

Check task manager...something sucking up cpu cycles?

 

thanks for your info. checked the process and found
PresentationFontCache.exe is hogging CPU.
after kill the process, discharging rate is droped to 10000MA+
which mean 5 hours battery life. will use it for few day and see how.
