Hi guys,

My new Lenovo Y520's battery life is very bad, it lasts 2h or less on Battery saver mode with 50% brightness, any tips to increase it ? Please help me !

Thanks in advance.

Is that battery life while playing games?

 

If NOT then that is just bad battery. Can you check how is the battery health in the Lenovo Settings?

You can also download third party tools to check battery health.

 

I think Lenovo will have to replace this battery.

Hi,

No, this battery life is just for web browsing. I have just Firefox opened and i close every background application.

In the Lenovo settings, the battery health is described as "good".

Btw, i have the I7 model.

Less than 2 hours is not good I think on battery saver.

 

Check the wear level on the battery. I think you can contact Lenovo support if you plan to use this laptop a lot on Battery, it should be replaceable.

There is no Lenovo support in my country (Morocco), so i need to travel to replace the battery.

I will test it again tomorrow, hope it will get better.

So, i let the battery drain under 10% and i shuted down the laptop and let it charge to 100%.

When i started it, i saw that the baterry life was predicted as 3h40min, but it is instable, now at 90% it says the battery should last 1h41min. I don't understand why, it is very weird.

Re: Lenovo Y520 - Bad battery life

The time can change based on your usage, it is just a prediction. If you suddenly start playing a video, the battery will show even less time, if you start playing a game, it will show even less remaining time.

 

As for the current scenario, 50% brightness / battery saving, I think your battery is providing less time.

 

I know Y520 has a smaller battery, but my Y720 provides about 5 hours on 50% brightness/Balanced plan while doing normal work (no games).
