Windows 10: Why is my battery capacity so low compared to its intended capacity?

I have had an XPS 15 for almost exactly a year, and I was noticing that my estimated battery life was also around 2 hours even when fully charged, screen at minimum brightness, doing basic tasks. I checked my battery report. For some reason I cannot attach a image, but the intended/original capacity was 84292 mWh, but is now 59440. I feel like that's quite a lot, especially for one year of use? How can I fix this?

Battery FULL CHARGE CAPACITY Reset

Yves,

"Full charge capacity" means the capacity that the battery is managing to achieve. It is not a limit set by Windows or anything else; it is merely a reading of what the battery can actually do. You can use the comparison of Full charge capacity with Design
capacity to decide when to buy a replacement battery [I do the same regularly].

Full charge capacity will always decrease over time as the battery wears out. This is a chemical phenomenon not a Windows-imposed characteristic.

Windows display of "Fully charged [100%]" means - the battery is currently at 100% of what it is able to achieve. In other words, "Fully charged [100%]" is relative to Full charge capacity.

Sometimes, you can find that cycling through the battery three times** can improve the Full charge capacity a bit.
On at least one of my batteries, the maker recommends doing this every three months. But doing so is using up even more of its remaining life so you can complete this procedure only to find that you are worse off afterwards.

** In other words, loop through this three times -

• remove the AC power
• use up the whole charge by using the computer
• recharge fully

Battery capacity rapid drop

Hello Jescott418,
I am Jaspreet Singh.
The criteria is usually how much the full charge capacity is for the battery i.e. how much charge it can store as compared to a new one.
Going by the fact that your device is just 4 months old and has 79% capacity of a new battery there is a defect and I would recommend getting it replaced under warranty.

 

A higher capacity battery for E51?

After using E51 for nearly 2 months, I found the battery is not really long lasting.

Not to say 1,050 mAh BP-6MT is "low capacity", but with the function in E51, the battery consumtion is really huge, compare to previous model, especially WiFi and HSDPA.

I need to recharge my E51 twice a day, imagine.

Actually, I'm looking forward to acquire a battery with at least 2,100 mAh or more (am I asking too much?), to fit in E51.
