X230i tablet battery life only 2 hours?

2012-09-07, 2:06 AM

I'm getting a very short battery life on my new x230i tablet. 

 

 I have it on reduced energy consumption. Power Manager says I'm using 8-10watts (fluctuating). But it's estimating only 1:42 of remaining time, with 72% battery life. In my experience, it is generally lasting less than 2 hours on a full charge. I have the regular battery, FRU Part number 45N1075. Power Manager battery tab says the battery condition is "Good".

 

Power use tab shows CPU 33% and GPU 100%. Windows task manager says CPU usage is hovering around 10%. Keyboard backlight is off. 

 

What battery life do others get when they are using 8-10 watts of power?

 

Is this just a defective battery that I should ask Lenovo to replace?

Ooops I clicked "me too" by mistake! ow to "unclick" it?

Anyway, it seems that 45N1075 is 0A36285 battery which is only 29.50 Wh As your laptop uses 8-10W it should give you up to 3 hours. Remember that you cannot drain your battery completely as there is always something left for safe shutdown and as you use your computer there are aways power consumption spikes just because from time to time applications require to do some calculations or access disc.

As in X220t even in "Energy saver" power plan there is some room for little more power savings, modify it to decrease power consumtion even further.

Or get 52+ battery which is six cell and should give you twice the running time.
