ManyLumia phonemodels are unfortunately infamous for their battery drain issues. Although users have been complaining for years about fast battery drain, only recently has Microsoft officiallyacknowledged the problem.
Microsoft officially admitted there was abattery drain problemon certain Lumia models only when the Windows 10build 14379was released.
The tech giant then rolled out battery improvements formobile deviceswithbuild 14385andbuild 14393.
While these fixes and improvements have reduced the intensity of the battery drain, many users are still experiencing battery issue on their phones. More specifically, it appears that only certain phone models are concerned: Lumia Icon, 930, 830, andLumia 1520.
Here’s howusers describe the problem:
hi gang i have the same problem when i updated from 8.1 to win 10 on my nokia 1520
the battery lasts a couple of minutes if u r taking vid or pics […] my wife has a 1520 still using 8.1 no prob my daughter has 930 using 8. no prob
so do not update to win 10do
microsoft read these posts because it is all over the internet […] i have to take a battery back up to use it but the battery drain s in a flash
As far as the root cause of this issue is concerned, users’ comments point to one main culprit:Cortana.
Many users noticed the battery drain and overheating issues began when they turned onCortanaand pinned it to theStart screen. Users then turned offCortanaand unpinned it from theStart screen, and it appears this solved the problem.
They repeated theprocessto see if their hypothesis was right, and it turned out to be accurate.
However, it is absolutely necessary to unpinCortanafrom theStart screen, because if you simply turn it off, the battery drain problem persists.
Yes, I have tried all variations ofCortanaon/off and pinned/unpinned. The only combination that prevents the overheating and battery drain is Cortana OFF and UNPINNED. I’ve even tried removing some seldom used live tiles from thestart screento eliminate the possibility of overtasking the CPU.
How can i solve battery drain with Nokia 1520?You can fix the problem simply by turningCortanaoff and unpin it from theStart screen. In most of the cases,Cortanais the main reason of the battery drain. If this doesn’t help you, try using the Battery saver and turn off idle apps and services.
For more information on how to do these things, follow the steps below.
What can I do if I have battery drain and overheating issues on Lumia 1520?
Particular solution – Unpin and Disable Cortana:
Of course, it’s possible that this workaround only diminishes the battery issue on Lumia 1520 running Windows 10 Mobile builds. If this problem prevents you from properly using your phone, you should also considerrolling backto the production OS.
Other general solutions you can apply:
Use the Battery Saver:
Set a shorter duration before your screen times out:
Reduce your screen’s brightness:
Use a dark background:
Go toStart > All apps list > Settings > > Personalization > Colors > select Dark.
Turn off idle apps and services:
Battery drain is a passive problem but overheating is an active problem that can cause serious damage to your hardware if you don’t take any action. Our solutions cover both issues and can improve your Lumia 1520 usability and lifespan.
