bruinator Posted January 8, 2017 Share Posted January 8, 2017 i have a asus x550za laptop which i hardly use. it is about 1.5 yrs old. I keep it charged at all times. When i disconnected it from the charger today it lasted less than 2 hrs before it needed again. According to asus it should last between 5 to 7 hrs. Why is the battery draining so quickly and what can i do to fix it? thx Link to comment Share on other sites More sharing options...
dMog Posted January 8, 2017 Share Posted January 8, 2017 drain it completely charge it and use battery power only for a few complete cycles ,,this may help Link to comment Share on other sites More sharing options...
knowledge-Spammer Posted January 8, 2017 Share Posted January 8, 2017 maybe time for a new battery ? but u can do little thing to save battery power Link to comment Share on other sites More sharing options...
debebee Posted January 8, 2017 Share Posted January 8, 2017 Must be a dying battery. If. you charged it 300 cycles, it will be near the end of its life.. Or you have software that are battery eaters... Link to comment Share on other sites More sharing options...
andy2004 Posted January 8, 2017 Share Posted January 8, 2017 Batteries in laptops drain quickly for various reasons... 1. what your doing on the laptop... listening to saying mp3's compared to watching a high resolution movie... mp3's battery would last a long time... watching a movie it would last about 1/3 of the time... playing games highend would also cause this... 2. use of the laptop... ie constant plugging it in to recharge the battery when its still above a certain percent.. or leaving it plugged in and fully charged.. when you could actually remove the battery whilst its plugged into the mains and used via the mains, only plugging in the battery when you need it portable or if theres a power outtage and you need to do something.. causes the memory effect in Ni'cds.. not nihms. it is actually a good idea to let the battery drain and then fully recharge it.. which keeps the battery healthy... example would be my brothers laptop for which he has had the same battery for years... 3 years i believe, maybe 4.

dac Posted January 9, 2017 Share Posted January 9, 2017 If you keep a battery charging all the time that will shorten the battery life by 1/2 Link to comment Share on other sites More sharing options...
lurch234 Posted January 9, 2017 Share Posted January 9, 2017 Here is some advice according to the four sources I've read up on the subject. You should never let your battery drain completely. Doing that uses up one of its finite discharge cycles. Experts agree that you should ideally stop charging your battery at 80% And, still ideally, charge it when it has 40% of its power left. Quote Cadex Electronics CEO Isidor Buchmann told WIRED that ideally everyone would charge their batteries to 80 percent then let them drain to about 40 percent. This will prolong the life of your battery — in some cases by as much as four times. The reason is that each cell in a lithium-polymer battery is charged to a voltage level. The higher the charge percentage, the higher the voltage level. The more voltage a cell has to store, the more stress it’s put under. That stress leads to fewer discharge cycles. For example, Battery University states that a battery charged to 100 percent will have only 300-500 discharge cycles, while a battery charged to 70 percent will get 1,200-2,000 discharge cycles. Some said that letting a laptop plugged in should be of no consequence since batteries stop charging when at 100% and power is used solely to feed the laptop. Cadex Electronics (in the above quote) disagrees with this. There is a consensus that heat contributes to shorten battery life. For your immediate problem I would go in Power Options and customize your laptops power usage. Setting a minimum/maximum percentage usage for the CPU, choosing a power saving option for your wireless adapter, turning off the HDD after "x" minutes, hibernating your system when not in use and shutting off the display after a while when you plan on taking a break...

bruinator Posted January 9, 2017 Author Share Posted January 9, 2017 After having the laptop for 1.5 yrs and hardly use it, I find this unacceptable. What would you guys do? Asus gave me a ballpark figure of $330 just to look at it and I told the guy that is crazy. Ideas plz? thx Link to comment Share on other sites More sharing options...

bruinator Posted January 9, 2017 Author Share Posted January 9, 2017 So you guys think this is a battery needing a replacement for sure? This is the only laptop i have ever bought or used. Link to comment Share on other sites More sharing options...

Kalju Posted January 9, 2017 Share Posted January 9, 2017 When you said, it worked for 2 h before new charging, then the battery is completely normal. Power scope is about 70% of the original, and it is also absolutely normal. You can buy new and get a few more minutes longer use, that's all (of course, under the same conditions). Buy and try. Lithium-ion battery isn't so expensive. Your original battery capacity is 44W/h, but always may use batteries higher capacity. But if you are buying, look at the time when it was made. For these batteries do not have matter whether they work or they are in stock. Ageing goes in almost the same way. It is about 300 charging or 1 year in stock, it is the same.

Kalju Posted January 9, 2017 Share Posted January 9, 2017 Don't know, it is necessary to look at the offers. I bought myself the battery about two years ago. But as I said, if it is cheap, see release date, it is very important. Link to comment Share on other sites More sharing options...

Kalju Posted January 9, 2017 Share Posted January 9, 2017 No, when the content is made, but usually the trusted resellers don't sell old products. You can calculate in this way, the capacitance of the first year will fall about 20%, ie if new is 44 W/h, if passes year is left about 34 W/h, if two years is gone, is left about 25 W/h etc. It is why the release date is important. Usually the components date is nearly the same which is whole battery release date. Original: 2950mAh and 44Wh/15V Link to comment Share on other sites More sharing options...
Administrator DKT27 Posted January 9, 2017 Administrator Share Posted January 9, 2017 You need to remove it from your laptop, look at the model number of it and then search for it's price online and such. Link to comment Share on other sites More sharing options...
dac Posted January 9, 2017 Share Posted January 9, 2017 A quick search looks like $20.00 - $ 60.00 depending on quality battery you want. Link to comment Share on other sites More sharing options...
