![]() ![]() Some of this processing is important like e.g. If you stop using it the phone is aiming to go to (3) as fast as possible.Īnd here's where wakelocks are important: as our phones as smartphones they tend to do background processing. Now as long as you use your phone it's in (1) and does not leave that state as long as you keep using it interactively. The transitions are from (1) to (2) and finally from (2) to (3). sleeping (that's you phone favorite state) They will cause an erratic behavior of your phone, causing more harm than good.īasically the phone has (simplified, kernel devs don't shoot) three states:ģ. There are many poor implementations that make use of wakelocks and BBS helps making that transparent.Ĭaution: do not use and wakelock supressor tools. Wakelocks are not bad per se, they are a tool. Wakelocks or to be more precise partial wakelocks is a pattern than helps devs to make sure that important pieces of their code do not get interrupted. ![]() I'm a quite heavy user because I spend a lot of time on the train every day reading my mails, surfing and listening to music but still my phone is off for a long time during the day and while I accept the battery being drained while I use the phone I care about it draining slowly while "doing nothing". When it comes to Android the most discussed and commented topic that I know is battery drain / battery life. What are wakelocks and why should you care about them? Please see here for more details.īetterBatteryStats has been tested on Froyo, Gingerbread, Honeycomb (3.1, thanks to daveid), ICS, JB, Kitkat and Lollipop on different ROMs and Kernels. You can read more about that here.įortunately and thanks to Looki75 there is a way to work around the restrictions intruduced by google in Kitkat and run BBS on non-rooted devices. Since Kitkat Google has revoked the permission for normal apps to access these stats (without valid reasons IMHO). from screen off to screen on)īetterBatteryStats is calling the "batteryinfo" service of Android to retrieve data already lying there without generating overhead. Use so called references BetterBatteryStats shows data for different samples over time: Process stats with User and System CPU time General "other stats "overview: Awake, Deep Sleep, Screen On, Phone On, Wifi On, Wifi Running ratios BetterBatteryStats provides an insight in following categories: It has been a long journey since the first version. I started BetterBatteryStats because I was missing the great battery history that Spare Parts allowed to call on Froyo.
