Insiders can now install the Windows 10 Mobile Insider Preview Build 14342 and test out some new improvements. As usual, the latest build brings both advantages and disadvantages. Such is the case with the latest Mobile build, with users now complaining about fast battery drain after install.

Microsoft has made public its known issues list for this build but has not yet included an issue more and more users have been complaining about: fast battery drain.

Lumia 1520 Build 14342. Need to charge the battery twice in 24h

The battery last only few hours.

Any tips to solve this problem?

Another user confirms:

I’ve had this since overnight when my phone updated to 10.0.14342.1001

Just as you describe, without any use (or apps open) my 930 is going from 100% charge to 0% in about 4 hours. I’ve had it charging for several hours now and it’s only up to 19%. It also seems that if you actually use the phone whilst its charging that the % doesn’t increase at all!

The phone is too warm to leave in my pants pocket 🙂

I’m hoping that someone has an idea of what is causing this, cause otherwise I’m going to have to use the reset tool.

So far, Microsoft has not issued any official statement or update acknowledging this unusual battery drain.

Yeah – I have a Lumia 930 with the same issue. No tips to solve it yet…. I hope someone will find something because with the 930 I only get about 4 hours battery when not even using the phone!

This is not the first time a build causes battery issues. Back in January, Windows phone owners complained about charging issues and fast battery drain after having installed the build, implying that Microsoft rushed the build release.

Perhaps the battery drain issue in the current build is due to the install problems many users reported. More specifically, the Windows logo freezes on the screen for minutes on end as if the build install stopped. (In actuality, it continues in the background, with the only solution being to simply wait about 40 minutes to allow the device to finish the install.)

Meanwhile, we suggest you try the following workarounds to extend your phone’s battery life:

  • Adjust screen brightness
  • Turn off your display after some time of inactivity
  • Activate battery saver when battery is low.
