[Windows Central Question]

my battery is draining so fast after the update to windows 10,which makes me very irritated by looking the battery backup.

How long after, when you first install Windows 10 it can take 24 hours to settle down, it is trying to Sync data from many sources and this is what leads it to run hot and use up battery.

Whenever I do an upgrade, I always get the process finish, making sure all apps are up to date as well, then I do an normal restart and leave the phone off for a few minutes, then hopefully it is ready to go.

Apart from checking for app updates go into settings and battery and battery usage by apps and see what is using up your battery, I find Edge to be one of the worst culprits so I click on it and set it to never allowed in background.

I also have a lumia 540 and I am easily getting 2-3 days of battery life

Try these methods:

1. Check settings >system > battery > which apps are using the most energy?
2. Again, in battery section, which apps can run in the background? Can you disable those you don't need? Keep messaging enabled to run in background
3. In battery section, you can also set up battery saver to kick in when the battery reaches a certain percentage. I keep mine on 100% so it's always on battery saver mode
4. In mail app, how often do you have mails to sync? Generally the longer the time period, the less the battery usage
5. What about brightness settings? Is it on high or auto? Auto is better than a fixed setting
6. If you find that messaging app uses a lot of battery, this could be because it's linked with skype. Go to messaging app, settings and unlink skype – this is on the 10586 builds
7. In photos app, do you have auto upload of photos enabled? If yes, try to not upload high res photos and videos unless you are charging the phone and on wifi
8. When you use some apps that are not data heavy like whatsapp or mail, you can use a lower network speed like 2G. It's what I do usually. I only use LTE when I have to use 6tag
9. If you're using edge for basic browsing, you could try using UC browser. Not only does it use less data but you can also disable images which means you save even more on data. The less data your phone has to receive, the less the energy used
10. In settings > privacy - check each of those settings to see which apps can use what. For example I can't understand why Word would need to access location info so I disabled that. There might be apps using services that they are not meant to use
11. Finally, keep wifi/cellular off when you don't need to have them on. The toggles in action centre are pretty fast so it doesn't take much time in switching internet on/off
12. Disable auto update of apps, you only update when you are ready and not when you are in need of critical things
13. For insider rings – reduce the amount of telemetry and feedback that you send – this can have a big impact
14. If you have Cortana tile pinned to start screen, remove it

Hope this helps you
