Problem is, I got battery left pro, and I stopped using it cuz it wasn't accurate. I have battery time, too, and battery left would not be in sync with my other apps.
Hopefully it's gotten better!

Its a bit confusing as to how to calibrate battery left pro.
Just go into your battery settings by opening battery left, then go to batteries, pick your battery "default or one you have setup", hit edit and turn on calibrating.
BUT DON'T DO THIS TILL ITS FULLY CHARGED.
Then allow it to drain to the bottom... don't help it and try to use it normally, then charge it back up "fully".. meaning to show at least 4220mv while still on the charger.. do this sequence again until it shows "accurate" as a readout.
At any time you can turn the calibrate back on and uncheck the "calibrate until accurate" switch to give it more info to work on later if you want.. just remember to turn the "calibrate" switch off again if your constantly bouncing back and forth from the charger as that will only confuse the settings.
Once its set, its pretty accurate.... an especially useful tool on extended batteries.
Just keep in mind "with any battery meter", time left accuracy is only accurate if you stay within reasonable predicable habits.
If you want to be able to use your phone like crazy sometimes and still have a clue as to how much life you have left, just watch your mv readings instead.
They will drop to below 3500 or thereabouts when it dies based on how aggressive you are taxing the battery when it goes dead.
