App Battery Drain-Settings:Battery Vs Systempanel

[dannyro77]

What is the better determinant of what is draining your battery? Settings: Battery or through the use or SystemPanel (the app) monitor?

I noticed my battery was draining a bit, so I checked settings: battery and noticed that it said YouMail was taking up 34% of the battery. Ok, so then I checked SystemPanel monitor function and it said YouMail was only using .01% of the battery over the last 8 hours-a major difference.

Anyhow, which is better to see what is really draining your battery? Is settings:battery actually pretty acurate or is SystemPanel much better? Systempanel did not even show YouMail as running on the phone.

Any help is appreciated.

Neither. Unless your battery screen is showing unexplained Awake times, then you battery is probably being consumed be your radios, which doesn't show up on these apps. You'll be chasing you tail for days.

There have been many instances with both my Nexus and my Thunderbolt, where I would be inside a building where there is particularly bad reception and my phone would start heating up in my pocket and the current monitoring apps would show high current draws. Yet nothing significant would show up on those battery info apps.

So basically, there are more things that consume battery than what shows up in the battery info screens. If indeed, you have a rogue app, you will see it in those screens. If however, you left the WiFi enabled when you weren't near a hotspot, or if you frequent places with poor cellular reception, you won't find any info on the battery screens that help you.

Is this still the same? There's no API to query the chip to get this data somewhere? I'm going nuts trying to find out what's draining my battery, cause there's nothing obvious in SystemPanel.
