Battery Level Bars poorly thought out

I find the Battery information in Settings to very poorly thought out.

The little green bars showing the Battery Level is pretty useless and hard to interpret for real information. It shows what the battery level was at certain times, but that is hard to get useful information from it. A much more useful graph would have been to show how much battery was consumed at those intervals, i.e. 10% of battery for the hours between 9-10 AM. This will correspond with Activity shown and a user can then see fi the activity actually consumed a lot of battery at that time period.

Showing how much is left in little green bars is hard to read and almost useless to get meaningful data out of it.

The funny part is if you got to the 6 days view it shows Battery Usage by day instead of Battery Level for the 24 hour view. Why not just do the same and show Battery Usage for the 24 hour view??

Inconsistencies and poorly though out metrics is NOT what I expect from Apple and shows why they are loosing their edge against the competition.

My guess is they intentionally chose to be generic and make a graph that you can just see large dips and from there investigate further yourself.

Percentage of battery usage isn't a metric. It lacks too much data to be used in the way you intend too.

If you were outside on a hot summer day standing in the sun at max brightness with poor cell reception and a specific app used 10% battery over the course of an hour how is that information really relevant? In a cool dark bedroom on wifi the same app might report as using half that over the course of an hour.

The battery gauge itself is based on real time data and algorithms from collected data (its a guess) since battery drain isn't linear and wear is constantly effecting its accuracy. For example if you never run the phone till its dead the accuracy of the gauge is effected. Usually you will notice it gets to 1% and stays there for 10-20x longer than the previous percentages.

Even a charger with higher output voltages (ex 5.25v) causes the battery gauge to linger on 100% longer than it will on follow percents.

Point is, percentage is there to just give you something a little more accurate than the gauge. However its no more accurate than guessing the gallons of gas left in your car from the gas gauge. You might be close but you wouldn't base further calculation off that guess.
