i have been using battery saver since i have started using windows phone 8.1.
i have updated to every NON-insider version (i'm not an insider), whenever it's available.
No issue till date, but after i have updated my mobile (Microsoft Lumia 435) to 10.0.14393.448, battery saver not at all working.
i'm getting push notifications from all apps, those having notification feature.
when i manually on battery saver there was no change is display brightness as it was there before.
tried soft-reset, but no use.
Battery saver is the best feature for a mobile. why it's not working even-though it's not an insider build.
