How to Solve Overheating Battery, Fast Battery drain, and Storage issues on Microsoft Lumia 950 XL

Are you experiencing storage issues and or an overheated battery? Is your battery draining fast?
Then keep on reading..

To be honest i didn’t experience the storage problem at first, because i didn’t have an external SD card mounted.
But as soon as i mounted one, the problem was there.
First thing I did was to do a quick search online to see if there where any solutions to the problem that had occurred on my new Microsoft Lumia 950 XL.
But to my surprise A LOT of people had the same issue but, but no one had a solution to offer me.
My first thought was that this had to due with the build, but saw over time that different people had the issue on different builds.
I could hard reset/factory rest my phone and it would run smoothly for up to 2 weeks and then the issue would return.

After doing this a couple of times i one day had enough!
Started to do some research on the phone and found out you are pretty much locked out from accessing the system inside of it.
My first thought was that this had to be due to a process that was running at 100% CPU power.
But i could not find any task manager. The only task manager i had found was the one that pops up when you hold down the arrow button.
With no applications running, why would it become so hot!?
An idea hit me to go check the battery settings to see if that would rattle out who the big bad wolf was, but sadly it was a dead end as it would switch between all the apps that i had been using and none of them looked suspicious at all.

I even tried to switch over to the Insider Program which provides you with new builds much faster than you normally would, but with no success of resolving the issue.

But something had to make my CPU go sky high, and i was super sure that is was a process running at 100% all the time. If here only where a way to see every process running. Including the system processes. Just so i could see what was causing the problem.

Anyway, when i activated the “Developer Mode”, I was able to connect to my phone through my computer over network using FireFox. After you enter the phone’s IP address your phone will ask you to grant access for your computer to enter. Once inside i found the deeply missed Task Manager.

Here you can shutdown and restart your phone. You can also uninstall apps, check EVERY process running, connected devices and network stats. Pretty cool if I may say so..

To my disappointment (Don’t get me wrong, the web GUI was superb!), there was NO process at all running at 100%. Not even the system processes looked any suspicious.
What was I to do now?

Some days later i got an idea. What if i install/flash the ROM (Windows Operating system) on my phone through my Windows 10 computer, instead of hard resetting my phone and use the stock version that is already flashed to what i guess is the recovery partition?
Now, i guess some of you might think about the same way we ROOT, and force flash new OS onto an Android phone. But it’s a bit different. The idea is the same, but different from Android you are NOT breaking any warranty. Do it on an Android phone and your phone is no longer protected under manufacturers warranty.


I recall to have seen that Microsoft had released a Recovery install tool for us to use some time ago. I went and found the “Windows Device Recovery Tool” (Only works for WP10 phones), and connected my phone to my computer through USB cable.

Since i already had the latest version installed i tried the “Reinstall Software” option.

The application downloaded the Operating System from Microsoft, and when complete, the computer started to Re-Flash my windows phone. If I’m not mistaken now, i can remember that this took quite some time. So be patient!

After the flashing was complete, my phone did a reboot. Once done i once again had to set it up from scratch as i didn’t want to use the backup i had of it that was stored on my OneDrive. (The backup it makes are great, but i wanted to start all over again.)

It’s now been 3 months+, and my phone has not even once shown sign of any weird battery drain, Overheated Battery/Phone, or Storage issues.
At most, i had my battery life last for almost 3 days without recharging it.

If you wish to try this method the only thing you need is the “Windows Device Recovery Tool” from Microsoft. The recovery tool will take care of the rest.

You can find the Recovery tool here..
