    If we add the total battery consumption by all the apps/services(total battery consumption) + total battery remaining, then should it not produce the figure of 100% ??

    Check Screenshots, it is not adding up to 100...

    Lol no. it's telling you how much of your battery has been used percentage wise based on your remaining percentage. if it added up to 100% your battery would be dead.

    Nope.. Android system used 7% means that it has used 7% of the 43% charge burned by your phone. It won't add up to 100 till you use your device from 100 % all the way to 0%

    Mate, could you please elucidate on this battery usage listing mechanism.

    Furthermore if android can show the battery usage to even 1% by some apps, then why can it not show for the remaining ~10%.
    What could be the reason for keeping it undercover :p

    Because the system will never be able to account for things like temperature where you're using the device, temperature of the battery itself etc. There are variables that are just not quantifiable to an accurate enough degree to display properly enough. as in if you play a game it will use more memory and processing power which is listed in the percentage you see but the actual temperature of your device matters for battery life. For example think of if you're stating your car in below freezing temperatures. it's rated to churn out a certain voltage at certain temps. same goes for phone batteries but it's more heat based. The warmer your device gets based on usage (games, multiple apps open at the same time etc) the more adversely it effects your battery. So.. if you want better battery life use aggressive doze (the device will auto doze apps when asleep) and use auto close high power usage apps (pretty self explanatory). You will see the percentage of the battery used by the app itself (only based off system usage etc, will not show other variables on the battery such as things I've listed.). does that make sense?

    If you notice the stats, the percentage does not show decimal. I think there are many more apps which consumes battery like 0.75% or 0.5% but is not shown in the list. This difference is present in other android devices also. I have noticed it in Note 4, galaxy S4, OP1 and OP3T

    think also that some processes are shared with android system, so you don't see that app in the consumption chart but you will see the growth of android os percentage

    I was thinking why android could not Club all these apps under 1 header. It's a possible thing and would help user to understand battery usage.

    When it comes to what I listed no it isn't an easy thing bc it is entirely based on usage on a per user basis. not all phones behave the same. not all batteries have the same capacity (even though the manufacturer uses the same size battery in each phone).
