Niantics have been trying to work out some of the issues and bugs that their app Pokemon Go seems to have but in their last update, they decided to do away with the battery saving option and the fans were not too happy about that.
Since the app itself does use up a lot of battery, having a battery saving feature meant that users can go a little further to catch em all but now, users will have to go on shorter trips just because they are running out of juice.
Well, it looks like Niantic have been listening and they have now announced that the fix for the Battery Saver feature should hep smooth things out. They added that the feature was removed because some users were claiming that the Battery Saver feature was buggy.
The update should be arriving soon which means you can start searching further away from the power source soon.
