my Andriod system under battery use is at 40%. Is it normal? i use to be able to get it to about 9 or 10% when using the connect and disconnecting the memory card method. Anyone has the same problem?
mine has a battery issue i think
pulled the battery at 40% and when i reinserted it it drops at like 10-14%
I was under the impression that, since the percentages have to add up to 100%, high Android System usage often is just relative to other, less battery-draining issues... not always necessarily a bad thing.
If you have a sketchy signal, "cell" will be high b/c it's constantly looking for a better tower, and Android System will be less. If you have a good signal, cell won't use as much juice and Android will be higher.
Android System contains things such as Settings, so if you dick around in your menus a lot that would contribute. When you reset the battery, it resets the usage chart. If you stop messing in the menus afterwards, maybe to test whatever changes you made, it might seem as if the battery reseat is what actually helped the issue. Lots of other things under Android System if you look at it... syncing, etc.
I had the same question when I got my Evo last month, and after a bit of reading it seems like high Android System usage is often just a reflection of the relative effeciencies in the other components.
