Robert zegers 21 oktober 2016 Bug The widget keeps getting stuck on aĬertain percentage. Martijn Kösters 5 januari 2017 Starting app Has to be done manuallyĪfter fully charging. This app has some ratings in the store indicating there are bugs:
If you use the phone more/less for the next hours it won't match reality for sure. The time left on these apps are always an indication based on what you did up to that time (and often starting from the time you stopped charging the phone). The app doesn't look like open source so reverse engineering it or contacting them seems like valid options. I have no experience with that app but first of all you'd want to know how that app calculates these numbers. I didn't go through it but this user guide from the authors might give you more insight. So the 3:40 hours is not linked to the 460mA the way I read this information. And based on the average of the last 5 minutes you have 3:40 hours left.

It's currently drawing 460mA with regular use having screen on full brightness. This rather means you have 91% capacity left, or in your case 3731mAh from 4100mAh. 3:40 hours time left(avg last 5 minutes). 460ma current consumption with regular use(fullīrightness). įirst of all I think your assumption is wrong. Samsung) also prevent access to this data. It’s important to mention that newer chipsets and operating systems have made power measurement much harder and in some cases even these apps are now having problems.

I know this because I’ve tested software like Trepn Profiler and Battery Mentor using a $700 Monsoon Power measurement hardware and found them to be within a few percentage points off in most use cases.
#Gsam battery monitor vs betterbatterystats how to#
If a developer understands how to access this data and interpret it, they can get accurate voltage and current readings, which can be used to calculate accurate power consumption. Every mobile device has one or more power management ICs (PMIC) and battery fuel gauge software. OEMs and SoC manufacturers must be able to measure power consumption using hardware and software-based methods. Most popular battery apps including GSam, Ampere, Power Tutor, and Better Battery Stats do not report accurate current readings. I would suggest that you revert to stock ROM and then observe to establish, if, there is a problem ( Could be custom ROM, kernel too) Now coming to your concern of battery problems - it's hard to say.
#Gsam battery monitor vs betterbatterystats android#
This post, though old sheds light on this How does Android calculate battery consumption by apps? Measurement of consumption per app and therefore total can also be misleading. Starting from Lollipop Android gives you an estimate of how long your battery is going to last, so the interpretation in other answer is validĪnother strange thing: when i look at Android's battery statistics, the sum of percenatges of the battery that goes towards each app(including screen) is only at ~50%.
Your app like other apps uses Voltage and inherently plagued with inaccuracies, so at best gives a rough estimate Li Ion batteries display a "flattish" voltage drop even though the amount of charge falls relatively steep as seen here at Fig.2 Yet another problem with Voltage based measurement is battery behaviour. The updating of the icon happens "every so often", we're told quite how often is entirely up to the manufacturer, rather than being part of the Android codeįurther voltage is NOT a true indicator of the amount of charge. We contacted Google about this, and the indication is that the battery data given in the Settings is the correct one. Updating battery SoC information is manufacturer dependent and not Android driven (emphasis mine and I haven't found any other source to dispute this) Is the battery icon on your Android phone telling you the truth? says that How often it needs to be updated (and reflect on the status bar), AFAIK is left to OEM implementation. Problems with accuracy using voltage sensing ( apart from current sensor bit) I don't know about your device but let's assume that it has only Voltage sensor as is common. For more details, see this How does the Android estimate the battery level without a current sensor? Even if the device has it, the kernel ( since you mentioned flashing ROMs) need to support it. Current sensors ( Coulomb Sensor) are available in some at OEM discretion ( Honor 6 for example). You need Voltage and Current measurements to get an accurate picture. They are usually based on Voltage measurements Battery monitors are an approximation and not accurate :
