Could this be cause it is trying to download stuff in background? My 1520 had 20 + apps that were retrying in the background. The phone was always warm so I knew something was a-miss. I am doing a hard reset and gonna leave it alone for a while .
The battery app doesn't function enough to show app usage. I'm seeing a high drain rate too which reminds me of using a Lumia 920.
Click on the highlighted link "Battery use" below the estimated time remaining. Works great.
Windows 10 build 10136 on Lumia 720. Battery drains too fast even in battery saver. Full battery drained in almost 6 hours even though I have used the phone for a period of 20 mins in total. All the other time mobile was in standby mode.
Mobile data, wi fi, bluetooth and NFC are off. Battery saver shows ~60% consumed display although the mobile was in standy by for most of the time.
Is this is a bug in the build or is there any other reason for the same?
