It will be nice if future updates include features you need multiple apps for now, such as system monitoring that is app/hardware specific.
it's nice to know that "android system" is using all my battery... but to know WHAT within the system is using it would be nice
without having to fish through so many 3rd party apps and screen them ourselves. that should be done by HTC/SPRINT for us. just like windows monitoring and controlling what applications use system resources. and granular control over these things is a must.
Nothing will matter until the software code that manages recharging and power use is addressed by HTC. That's also the reason the phone stops charging when full and then goes directly to battery use without ever resuming charging when plugged in (meaning the software is preventing trickle charging and may not even be allowing a true 100% charge).
I've charged the battery outside the phone once to test it versus charging inside the phone. The externally charged battery lasted about 20% longer, including keeping it's original full charge much longer. That's part of the reason I'm convinced the issue really is software-related and not the batteries themselves.
What would make things even more conclusive is if someone from this forum who has another brand of phone that uses the same battery could test the battery inside that other phone. I believe that would show the battery's not a problem at all.
Are you sure it never charges again? I was under the impression that testing revealed that it does start charging again (just at some currently unknown point)
One day if I'm bored enough, I'm going to figure out the best way to consume as much power as possible, roughly figure out what the consumption rate is, time how long it takes to consume say 20% battery, and then run that while charging (and hooked up to my Kill-A-Watt).Correct.
Simple proof - leave phone on, charging all night, wifi on, let phone merrily sync and so forth while you sleep. Next day, use phone while on charger - all day. End of day, take phone off charger, you find the typical rapid drop to +/- 90% or so - but not significantly lower, like 60% or or 20% anything you'd expect from whatever your day of use is.
Empirically, I believe the re-charge trigger point is anywhere between 82~92% - but that's not scientific.
If anyone feels like searching, back in June a couple of guys here used power monitors and tracked the charging activity from the wall - very cool.

We'll be able to see how long it takes for the charge to start drawing power again, and can roughly determine at what point charging is once again triggered.

How do you know it didn't resume charging? When you unplugged it, did it drop all the way down to say, 40 or 50%While I can't say "never", it did not resume charging once in the 10 hours I observed. That's enough for me to think it's probably not coming back to charge. I guess the next step for me would be to see if it runs out of battery completely despite being plugged in. At a minimum, I'd hope the software would just start the recharging process when it give the "low battery" warnings.
People like to blame "Bloatware" for "slowing down" their systems, but save a few msec on boot (leading to cries of "it's loading stuff that I don't want!") those apps are seriously just non-factors. Whether you use "ps" in console mode, OSMonitor or "System Monitor", those apps might be loaded (and swapped out when not needed- that's one of linux' strengths, esp for applications that are loaded into ROM in the first place) and not using a cycle of CPU once they've inited.I think it's the Sprint apps that are the culprit.
True. It would be cool if they had one central area for battery control. So that you can put a widget or shortcut onto your homescreen which when press links you to a page that has controls for WiFi, Brightness, Mobile Data, 4G, system processes, etc.

As far as I've seen, there is no transparent method on the Evo itself -- you need to resort to an external indicator of charging, like measuring the power draw from the AC adapter.
Furthermore time (alone) isn't necessary a good measure for drawing that conclusion. Hypothetically, let's say that the charger resumes float charging at 90% depletion. If in that 10 hours battery consumption is minimal and the battery is still about 90%, then that would sufficiently explain why no charging occurred.

It's just more Android misconceptions being lauded as facts. What I suspect people are seeing when they "swap ROMs and get better battery life" is the effect of a freshly-booted system.
Wow, Rig - if my phone is any basis whatsoever - I'd say you've got something, somehow, defective there.
My light day on a charge, unplugged mind you - is 12 hours or much better. On a heavy day, I can drain a battery in 4 or 6 hours.
So, if I'm getting never below the mid 80s when unplugging from a hard day's use - and never have such a bad result with ANY sort of overnight charge - then I'd conclude that mine's golden, there's insane variability, or you've got a lemon.
