Our apps get the information on the battery level directly from the Android OS. The battery level your app shows is all over the place! After a full charge it said 100%, but now after a full charge it shows less than that. HINT: For a quick way of pulling up this information in Battery Notifier Free BT or Battery Notifier Pro BT, go to the dashboard, touch the settings icon (three vertical dots in the upper right corner of the dashboard) and then select Battery use. When you plug in your charger it will also show you here how much time is remaining until the battery is fully charged. (NOTE: It is generally not a good idea to allow your battery to drain all the way to zero, and for the best battery life you should charge it once it drops to 25% or 15% at the most.) Go to Settings - Battery and you will see the estimated time remaining for the battery until it reaches zero along with a graph. (For example, a very popular battery app competitor's 'estimate' of our tablet's battery time left went from saying our tablet had 12 hours left at 88%, to 9 hours left at 87%.)Ī much more accurate estimate is available if you have Android 5.0 (Lollipop) or higher, (as of 2/7/17 64.8% of all Android users). We don't include a built-in calculation, as these 'estimates' tend to be wildly inaccurate. Does your app have estimated battery time remaining?
