Why is it that Samsung devices (and perhaps others) show the battery charge remaining in multiples of 10% whereas other devices are able to show a more accurate percentage like 96% etc?
Is this a limitation of the hardware or software and can this behaviour be changed to show an accurate (non-multiple of 10) display of the battery remaining?
I don't believe this is a hardware limitation, but just the way the phone's manufacturer chose to implement the battery reporting code. My Droid 2 also only showed by 10% increments. However, on my current setup I'm using the
Circle Battery Widget available on the Market and it displays the percentage in 1% increments.
If you visit the Market page for BattStatt, the developer's site for Battery Left Widget, and this Motorola Owners' Forum thread you'll start to notice a theme.
Several Motorola phones do not report their battery levels in increments of 1%.
Most likely it's a battery saving feature. Polling the battery state too often will drain it quicker, so manufacturers adjust the polling periods to sacrifice accuracy for better battery life.
