Battery stats

I unplugged my phone at 630am to go to work today. It is 237pm now. I haven't plugged my phone in all day and my battery stats says 1hr 44min since last plugged in. When I refresh it just changes the seconds. Also there is no where telling me my battery percent. Anyone else seeing this?

Help yet again.

Ok installed EB01. Everything's working no problem at all. Then I was looking at my battery icon. It was at 40-30 percent then all the sudden drops down to 10% it doesn't even try to hit 30-20 % etc. Is this a known bug or is there a fixed to this? I've tried wipe and battery wipe on the red clock work.I'm clueless what next to do. No task killer. Juice defender etc. Thx

You charged the phone 100% and then cleared battery stats?

Yes.

The fact that you are giving battery life ranges implies that you are judging by the stock battery graphic ib the upper right, which is remarkably misleading.
Install a better battery mod/theme or simply download OS Monitor and look at its Misc tab.
Swyped w/ XDA App. When in doubt, mumble.

Thx I'll do that.

Weird. Download battery % app. Phone battery icon is at full bar. But then app battery % is at 80% . That's weird. This a known bug to EB01 Stock dedoxed?

What I've noticed on some is that they yank the battery when it's full during a bat cycle based off of what the stock image on the upper right says. What is more then likely the case is that you wiped (or didn't wipe) the battery when it was actually at 100% so it reads at 100% when it really is at 80%. Best thing to do is charge the phone till the bat app says 100%, then wipe bat stats after letting it charge for an addl 10 min. Then full cycle the battery and charge again and report back.

And I thought it was battery drain

After flashing Ics my battery couldn't seem to stay high so one day, I took the liberty of finishing the battery and...

This pic is just soooooo funny. I have no clue why but looking at that makes me laugh XD

Yes, I have to agree. This has also happened to me. I have actually had this happened when I turned my phone off one day. Before turning it off it had 60% battery, after a minute I turned it on and it said 20% battery. Also, has it happened to you that you charge it leave a couple of hours and when you unplug it rapidly falls to 70% or less? LOL! But it is nothing a full charge and batterystats.bin wipe wont fix.

Wiping battery starts has nothing to do with reported battery percentage. Similar results can be obtained by setting your phone face up on the coffee table, watching any random show on tv, and doing Zumba for 30 minutes. In other words... none.
Battery stats, which is only a list of the apps that have put a demand on the battery, is already cleared each and every time the os is rebooted

This is what I have read on the XDA forums and it has worked for me.
Completely charge your phone to 100% (Full battery charge) without unplugging. Once it is charged, without unplugging it, reboot to recovery and wipe battery stats in the ADVANCED section. As soon as your wipe it, very quickly unplug the phone. (as fast as possible). Once you do this, reboot your phone and completely drain it to until it turns off and you cannot turn it back on unless is plugged. Once it is drained charge it completely full withot unpluggin it or turning it on.(Best time to do this is at night, since you are probably not going to use it while you sleep). After that just use it daily. You have to give it a couple of days so the battery syncs up. Hope I helped out!

No offense, but what you have read is incorrect and is rooted in a misunderstanding about how the os and li-ion batteries work.
1. Wiping battery stats does nothing pertaining to charge indication. The file cleared is an already blank file that lists nothing more than a list of the apps that have consumed power. This file is cleared by the is on every reboot already.
2. Completely draining the battery shortens its serviceable life.
Any "results" that are seen by doing the above are merely attributable to the placebo effect.

Battery weirdness

I've noticed lately that my battery has been draining pretty quickly, but I've since chalked that up to an old battery that just needs replacement. But I noticed today that my battery ran out and my phone shutdown, but I went to charge it and immediately turned it back on and noticed that it read 50% charged. What is happening here?

As you already changed the Battery, I assume you'd have done calibration as well. If not, please consider doing it.
I have the same problem but I suspect that is because of battery, I'll be changing that soon and will write back

I'll leave this here in response to the advice to calibrate your battery

To get the best life out of a charge, flash a ROM on a full charge and then let the battery die and fully recharge it.

[Q] Battery Meter

My Nexus 10 is shutting off with the battery status showing 3% and won't turn on until the charger is connected. How does I recalibrate the battery meter?
