    Hi everyone I've got a problem with my Surface 3 battery. I charged it up to 100% after few second dropped to 98% and it gave me an estimation of 3 and half hours life battery, then at 95% it gave me an estimation of 11 hours also using word or photoshop. However as soon as i browse on internet the estimation drop at only 3 hours i am going crazy with this device. Furthermore I left the device on sleep mode with 72% of battery from 8.00 pm and at 7 am I found the battery 38% how is it possible. Someone can help me? I updated the device so it has the last windows 10 and the last firmware.

    First, the time remaining estimate should be completely ignored. It is not in any way useful, for the reasons you have stated. this is simply how it is.

    As to battery drain, you'll need to perform a sleep study to work out what was going on. It's not a one of case though, many people experience this.

    What operating system are you on?

    Nobody has manged, on average, to get anywhere near what Microsoft claimed for battery life but that's the cases with most portable devices. If you read enough threads on the forum you'll pick up some tips on how to extend the battery but you'll never use it the same way Microsoft did to get that figure. With that said you should be able to average well over 5 hours.

    Thread moved to the proper forum.

    That should not be happening. You have some application or service running in the background and consuming resources, whether it is something you installed or malware. Some anti-malware are very resource consuming. I suggest you get rid of them and install sth light. Personally I trust in microsoft's firewall which is also quite light. Also chances are that that's what is killing your battery.

    Most people aren't putting any money on the battery indicator. What counts is the actual total battery time when it runs low/out. The meter is poor at estimating.
