Just started using an Android phone and left it overnight to see how long it would last. After about 10 hours the battery is still at 100%, so could there be some kind of delay when it comes to the battery percentage or is it something else? My phone is a Leagoo Lead 4.

  • Did it suddenly drop to 90% or below? If not, then probably there's no delay and it's indeed 100% since the phone wasn't doing anything at all? (no internet connection, background tasks, alarms, etc). Android is actually battery efficient if implemented properly. – Andrew T. Jul 27 '15 at 8:26

    @AndrewT. 100% after 10h on battery is pretty unlikely, even for a "naked" system (no user-apps installed, not initiated at all) running in airplane mode -- especially when taking a look at the device specs: a 1,600mAh battery makes me very much doubt that, unless the device is switched off altogether ;) – Izzy Jul 27 '15 at 9:54

    After 10 hours the battery is still at 100%,did you had your phone plugged in to a charger?? Because 10 hours with a 1,600mAh battery and still 100% is just impossible... And why did you add the tag mobile-network? – Thomas Vos Jul 27 '15 at 10:27
  • @SuperThomasLab the phone was not plugged into a charger and was left to drain. – Mat Jul 27 '15 at 11:39
  • @Mat - what is the status if the device is used continuously for like an hour or two? – MANI Jul 27 '15 at 16:42

You could try some apps like Battery Monitor to check the usage of all apps. But your let's say "problem" is not so unusual. If you want to be 100% sure about that, try it this way. Completely drain the battery out, sou your phone turns off. Then plug it in to the charger for 8 hours. (That's enough to charge it to 100%). After it has been charged plug it off and leave it for 10 hours. But! Don't install any new apps on it. Just to be clear, apps like Viber , Whatsapp,Messenger,Facebook... even if you closed them they are still running, because if not you would not get messages. Besides display and games these apps drain most of your memory (RAM) and battery. I hope this helps.

  • I have downloaded a Battery Monitor and left it for about 40 monitors and used 1%, most of the app usage is from Omich Player. Usage seems to be quite light puu.sh/jeyc8/d95a7a089a.JPG – Mat Jul 27 '15 at 9:46
  • 8 hours? I am sure devices only take 2-3 hours to go 0-100% – Dan Brown Jul 28 '15 at 8:59
