So you know those old wives’ tales about tweaking your battery stats improving your battery life? Well apparently those old wives’ tales aren’t true. In fact— Google says you’re wasting your time by fiddling around with your battery stats or using battery tweaking apps. Google’s own Diane Hackborn recently addressed this common myth and urban legend of tweaking battery stats improving your battery life:
“Today’s myth debunking:
“The batterystats.bin file in the data/system/ directory is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the “Battery Use” UI in settings.
That is, it has deeply significant things like “app X held a wake lock for 2 minutes” and “the screen was on at 60% brightness for 10 minutes.”
It has no impact on the current battery level shown to you.
It has no impact on your battery life”.
This response was squarely aimed at the minority of advanced Android users who like to root their phones and tweak things they probably shouldn’t. If you want better battery life, try adjusting your brightness settings, fixing your notification settings in your apps or just buy bigger battery for your Android device (if possible). So there you have it folks.
