Battery saver confusion

[chuckd1991]

When my phone had 100% charge, battery saver said I had approximately 19 hours left. Not long after, it was showing a 97% charge, but with 20 hours left. Anyone else experiencing this?

I guess The run time adjusts itself based on the battery drain and usage, I noticed it say 19 hours then back upto a day after left on stand by for awhile, then to 15 hrs after playing a game and then back upto 22 hours when just browsing on amazon.

Look on it as you would the fuel computer in your car.

If I have been driving around town a lot in my car and I fill it with fuel it will give me a "miles left to empty" reading of around 220 miles because I get about 10mph around town but if I have been driving on the motorway and I fill it then it with give me a reading of about 450 because I get around 20mpg when driving on the motorway.

Now if I have been driving around town getting 10mpg and I fill the car and then go driving on the motorway the "miles to empty" will slowly rise for the first 50 miles or so because it is calculating how many miles I will get before I need to fill again at the currant driving style.
