Feel free joinin Forums. Which win10 build you got? It is normal on older phones but on some older builds, you need to update

I've just installed the anniversary update on my Lumia 930 and the battery has drained within an hour of normal usage.

Have u tried a hard reset and/or a new charger? i find that after the windows 10 updates the the chargers take alot longer to charge the batteries on the phones now. Could be the battery isnt being charged properly and holding a charge

also go in battery saver and see whats using your battery and disable apps in the background u dont need go there and go to settings background apps

A few things you can try out:

• Check settings >system > battery > which apps are using the most energy?
• 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
• 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
• In mail app, how often do you have mails to sync? Generally the longer the time period, the less the battery usage
• What about brightness settings? Is it on high or auto? Auto is better than a fixed setting
• 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
• 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
• 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
• 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
• 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
• 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
• Disable auto update of apps, you only update when you are ready and not when you are in need of critical things
• For insider rings – reduce the amount of telemetry and feedback that you send – this can have a big impact
• If you have Cortana tile pinned to start screen, remove it

Hope this helps you

I had this list prepared months ago so some items might not apply

Generally after a major update, give the phone some time to settle down, like a day or two
