[Q] Weird Battery Issue?

Every time my battery reaches zero, my phone doesn't shut down. I have BattStatt on my homescreen, and it says empty. Which kinda freaks me out because if the phone's battery is empty, why is my phone still running? I never bothered waiting for it to turn off because I'm afraid I might damage the phone in some way just in case this wasn't normal.
So I want to ask, is this normal? I came from a Droid Eris, and the phone just shuts down after reaching zero battery. Just wanted to ask.

Hmm i have never heard of that happening.
I would say let it die all the way. You're not going to hurt anything. But that just me.
Maybe you have an infinite supply of power!!! Bwahahaha

That was my first thought, but unfourtunately realized thats impossible. Going back, does anyone else have this problem?

It's probably just displaying the battert wrong.
Recondition the battery and see if they will help.

let it die, recharge it to full, clear your battery cache, let it die again

I have noticed BattStat is not always accurate - it never matches what my system battery says. Maybe its showing 0 but you still have some juice left. Just run Angry Birds or Google Sky until the phone actually shuts off and maybe that will calibrate BattStat. I don't think it hurts to let the battery run out, but I don't know for sure.

Ugh.. getting mad at battery life!

I have not changed anything... I was getting 16+hours and still having between 15 and 20% left but the last two days I'm hardly getting 10 hours! WTF!
What is a good program for seeing what apps are open when they don't need to be? Would that just be like a tast killer?
Just a little rant... sorry. When I complain to my friends they just call me a nerd... I need to vent to people that understand, haha.

does your ranting require a new thread?

Wow people, how on earth do you guys get battery life of 16hrs. I can hardly get 3 hours on my phone...

Yeah, Its as pointless and useless as your post. Yet we both wanted to say something... so here we both are... wasting space.

Have a great day! Enjoy your battery.

you using the phone for straight 3 hours? if yes that's normal.
To the OP check the new apps you've downloaded.

Nope.. I use it moderately. listening to music for maybe an hour brings down my battery levels from 90 to 58% and this thing is draining 1% every 2 mins on standby...
Btw while I was charging my phone and it magically jumped from 8 to 34% in jus 10mins or so(I had switched it off before charging and after few mins of charging, I switched it on to find it on 34%). Is this a factor??

that's ridiculous, that must be an application eating up type battery

jumping percentage means your battery stats is ruined. wipe it, but the battery drain on idle mode isn't about the stats.

If you're charging via USB, you may wish to connect to AC. USB doesn't charge as fast and your phone (apps running, etc) may using power faster than the USB can replenish it.
If you're on AC, turn the phone off and charge it that way. If it continues to decrease this way, there is something seriously weird with your device.

I re-flashed bionix but the battery drain still continues.. Should I change back to toxic darky 9.5 and see how the battery on that thing is working?

{Battery Issues} Phones mysteriously cuts off and loses charge

one min my evo is on and battery might say it's at 49% charged. then out of no where, my phone will cut off and when i turn it back on, sometimes its completely dead. sometimes, it's showing 2-4% battery life left.
WTF is going on?

Is it a stock battery from sprint/htc or one you got from eBay or any other seller?

Ive been purchasing 2000mha batteries from eBay and they have been working great for some time now.
I believe that sometimes the length of your battery life experience will depend on the way you charge it through out your day and the amount of charging cycles you've used during the life time of that battery.
Sure I do agree that certain things can be done to improve battery life, but sometimes... It's just time to discarded it and get a new one, imo anyways.

I figured that, but I didn't wanna get a new battery if it was a bad ROM flash or something.. but I'll use my extended battery when I get home and see how it plays out. I just that damn bulky Ness to that battery.

Change roms and wipe battery stats in recovery. If its still acting funky then it must be your battery. I think sprint replaces them for free if you tell them that your battery is disfunctional

I had same problem when I bought my 3500mah sedio battery. So I exchanged it. Most likely there is a problem with your battery.

Yeah, just did that. Think it was over used. Regular charge, trickle charge, over charged. It's toast.

Been running the new battery over a day now. No restarts at all. Guess it was the battery.

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...

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.

Nexus 7 power spikes.

I'm not sure what's happening. My Nexus 7 remains idle most of the time, yet I get pretty bad battery drain and then when I check the battery history I see this. This happens during every battery drain.
Any ideas guys?

Wow, have never seen that on any device! Install Gsam or better battery stats if you are rooted to see what's going on. My best guess, it's a hardware issue.

Have you already tried reformatting? Kind of a pain, but that's the only thing I can think of.

Try contacting Google or the seller they might give you a replacement.

That happened to me once or twice. These spikes are only visible on the battery graph in settings app. I use an alternative battery monitor app from Google play and it does not show any spikes. Also battery life seems pretty in line with what other people report. I simply ignore them since they do not seem to affect battery life.
Could it be caused by the wireless charging functionality being triggered by other electronic devices in house?

I saw the same problem in the G+ community there, but it's Gelexy Nexus which updated to Android 4.3 recently

Hey everyone,
My Nexus 7 (2013) is having the same problem with battery graph. There are about 2-3 spikes to 100% in every discharge cycle.
I noticed this problem has been reported in different cycles, but no one seems to be able to give a definite answer of what the source of this problem is.
BTW, after a reset to factory settings, the problem still persists.
ANY idea why this is happening???
