Hey everyone. I'm having an issue with the battery stats of my Acer Liquid Z500.
When I charge my phone, sometimes the battery stat freezes at some point, 35%, 28%, 45% for example, for some time. When the phone feels like it's discharging, the battery stats come down really fast, like 1% per 15 seconds, until it's off.
I've tried booting into recovery mode and checking if there's any option to wipe battery stats, but there's not.
I've tried factory resetting the phone but it doesn't work.
I was wondering if you guys could enlighten me about this issue. It's getting really annoying.

Had the same problem once on a different phone. What I did to solve this was quite simple: after battery percentage has frozen, I shut off my phone completely, so it can charge without interference. So just wait until the phone has charged completely. Another option would be to perform a simple reboot after the freeze.
If this doesn't work, maybe you have to re-adjust your battery by charging it to 100% and then let it discharge to 0% and then do a full charge afterwards.

Thank you so much! I'll try that.

No matter how long my g tablet is plugged in,
it does not charged until the battery meter says 100%.
It always get charged upto 96%.
Is there anyway to fix this problem?
Is it something that can be fixed by clearing batterystat.bin?
If that so, can I do that using adb? Thank you.
khunny,
This is pretty common with the G-Tablets.
You can run it down all the way and then go into CWM and tell it to reset the battery stats.
But often as not that doesn't change much.
My personal advice (I have one that often does the same) is just ignore it. If it's 96%
you've got no problem and at less than 10% you better be thinking "charge."
Rev
Mine only charges up to 96% as well. Gonna try to reset it in CWM after it drains. Hopefully it works, cuz while having it only go to 96% isn't a huge deal its something I would like t be able to fix.
search is your friend
It is normal. Gtab treats 8.3V as 96%. In theory, 2cell li-ion battery 100% of charge is 8.4V. But, such battery does not like to be overcharged (it will shortened battery life).
mine did charge to 100 percent before installing vegan 5.1 supplement? Now it charges to 98 no matter how long i leave it plugged in? There has to be some way to alter the battyer stats to show 100 percent if it is??
Mine finally got to 100%
I had this tablet only for a week or so. I have installed Vegan 5.1.1. I noticed the battery only charged to 95% or 96%. I have drain the battery all the way, and then "Reset Battery Status" in CWM. But, it did not work the 1st time. Then, I drained it again. After the tablet shuts off automatically, I would push the power button to turn it on a few times to drain it more. Then, I reset the battery status in CWM, AND, I "Fixed File Permissions" right after the battery status reset. Then, reboot the device, and it reached 100%
Note: I drained the battery at work, tried to turned it back on about 3 times after it shuts itself off. After I got home, a few hours later, I turned it back on one more time, and the battery showed 2% and stayed on for quite a while. Not sure why that is. Hope this helps.
Hi Guys,
I know there's been a few threads on this, but a lot of them don't really answer what I'm about to ask.
I've noticed lately that my battery has been losing about 10% in the first half an hour, then goes down quite slowly which makes me think I need to wipe the battery stats. However a lot of people keep saying 'wipe battery stats' then fully drain, which seems like a ridiculous idea knowing what we know about how badly batteries react to full discharges (on a bad day you can actually knacker the battery), so what I'm asking is can I just wipe the battery stats at 100% without discharging. The user manual never said about fully discharging my phone when I first got it so why would I need to do it now? Also, this concept of bump charging, how would I do it on a Galaxy I9000
Thanks very much!
Breaking you battery through a full discharge? Never heard of that.

again though, a full discharge, is that wise?
You need to calibrate your battery. There is an app in the market..just search "battery calibration". Charge your phone to 100% then use the app to wipe the stats. Let your phone discharge. Full discharge is not necessary. Discharge to 1% then charge it back up to 100%. Good to go. If you don't want to use the app, you can wipe your battery stats in recovery which accomplishes the same thing.
When you drain your battery, your phone will not just stop working at some point, it will shut down your phone in an orderly fashion before you battery is fully depleted.
When I drain my battery and my phone shuts down because of it, I can still switch it on again and it will work for a minute or so after it has fully started before it will switch off again.
Could I not just wipe the stats and not fully discharge? Or does that achieve nothing. I'm pretty certain it's these battery stats. Today, it went down to 84% in seconds. I've noticed if I plug it in, it charges full, unplug, then plug in again, it starts at about 91% and does the rest. Sound like a battery stats issue?

When you charge, you phone says "charged" as soon as it hits 90%. Check the about-menu in settings (or in my case at least, the lock screen while plugged in) to see at what percentage you really are when your phone says it's charged.

Oh right I didn't realize that. I'll try it. I've just unplugged it and it immediately said 98% so I plugged back in. This time when I pull, I'm going to wipe the battery stats. I don't really want to discharge fully, because even at 1% it's not great for it. If anyone can state categorically that I shouldn't, tell me now please haha
For the past few days my battery has been charging to a max of 92%, whether or not I try unplugging the battery, leaving the phone on the charger, wiping battery stats, and doing all that I can to try to reset the battery stats.
Anyone have any idea?
UPDATE: My phone is still not charging past 92%, no matter how long I leave it on, or what I try to do to fix it. 4167mv max
I have a similar issue, it's been like that for a long time for me. What ROM/kernel are you running? It might fix it to completely drain it, charge it powered off, reinstall ROM/kernels when it is completely charged and reset battery.
Sent from my MB860 using xda premium
drain it until it shuts off and then charge it all the way to 100%.
I too was having this issue after going from cm7 week 5, to week 8. I did what others were recommending and charged to what showed 4200mv, pulled the battery while still plugged in, put battery back in then after it showed 5%, turned it back on and Viola, 100% battery. Try it.
its most effective if you know your battery is fully charged, power it down, pull the battery, while the battery is pulled plug it into the power adapter, it will act like its starting to charge, but then instead of having a percentage, it will have a question mark. pull the power, put the battery back in, turn on, wipe battery stats in recovery and run with it...

I just started having this issue and cant wait to try it thanks for the suggestions.
when this happend on mine all i did was keep using it and it fixed itself. i ran it down maybe to 20% before I got to charge it again and it slowly creeped back up to 100%. took about a week.
I've had the problem, and have run the solution more times that I can count. But nothing ever fixes it permanently. Everytime I run the battery low, the levels get all screwy again. Maybe my phone is just worse than everyone else's, but I had to just give up on it. Would love a permanent solution, but so long as I'm running this ROM (CM7), I doubt I'll ever find one.

I'm in the same situation as you are... I had this problem for a long time now (Guess it has something to do with excessive flashing...) and no matter what kind of solution I do (Wipe battery stats via recovery, re-calibrate the battery, pull the battery out while charging and replugging it) it returns after a day or two.
I want to check if it has something to do with the battery or the device, and if I will remember to do so, I will plug my spare battery for several day's run, but that is subjected to me leaving the comfort of my usual laziness....
Would love if there was a permanent solution as well, thou I doubt that too....
I've had the same problem on a number of different roms and at different times. I find that instead of mucking around wiping stats etc, it has always come good eventually for me.

Didn't really understand what you meant, did the battery percentage fixed by itself and gave you 100% at full charge on one day? out of the blue?
Or did you just got used to have less then 100% battery display?

First let the battery completely drain and the phone shut down by it self. Second step is to pull out the battery and leave it out for 10min, after that take a plastic bag and put the battery in it and place it in the freezer for 15min. after this palce the battery again in the mobile. make sure there is no any moisture on the battery. Then charge the phone without power on till 100%.
By following these steps this will made your battery to charge fully and more talk time

Um correct me if I'm wrong anyone, but doesn't cold kill the battery and shorten its life? I remember my mom always putting new batteries in the fridge and them only lasting a couple days compared to the ones left out that lasted a month or so with same use.

Haha, I got a good laugh out of this one -- you've got to be joking.
I've had this problem for a quite a while now with the Atrix and two different batteries. I've tried dozens of combination of resetting the battery stats, running the battery completely down, and powering up without the battery and hot swapping it in. The hot swap definitely allows me to finally recharge to 100%, but once I run it down again, the problem returns. I've learned to just live with the less than 100% reading -- battery still seems to last a full 24 hours for me.

That trick hasn't worked since nicad batteries in the 90s, and is a really bad idea with our Li-PO.
Drain the battery till the phone shuts off, charge back up while the phone is off.
If it still doesn't get to 100%, boot into CWM, wipe battery stats and power off the phone to let it charge again.
^^ I know it works because I've done this like 2 days ago, and many times before that.
I have had this issue as well for a very long time. I've tried the pull out, question mark, 5% thing and it usually only works for one cycle, then the next only goes to 97%, then the next to 93%, then 90%, and it continually goes down until I have to do it again. Hopefully a permanent fix can be found soon. I've tried clearing battery stats, draining it to 0%, then charging it fully. I've tried everything. As far as I'm concerned, there's no fix as of right now.
Thanks man this worked like charm of 100 witches and 100 warlocks having orgy and satin worship

★ATTENTION! I FOUND THE FIX!★
Turn phone off and plug it in to a wall charger. Charge it until your notification light turns green, quickly tap the power button to check battery level. (Usually shows 90%) If the notification light turns on, but the battery indicator is not at 100%, unplug phone, take out battery and put it back in. Now plug your phone. It should be 100% now. For the final fix: go into "Android Recovery" and select "Mounts". Mount Your SD card and Emmc. Finally wipe battery stats. Reboot phone.
This method worked for me. I am 100% sure this is the fix for this problem. This has to be done every time you flash a new rom or when your phone freezes and you screw up calibration by pulling the battery while it is still on. BTW, this is my first post so don't be mean to me!

Satin worship, is that like old fashioned polyester worship?
Not sure why, but I restarted my phone and it went from 50% down to 5 % power? Had it on the charger all night and it was still at 5%?? Took it off the charger for a few hours and im still at 5%. Tried wiping stats and had no luck? Any Help??

Drain all battery and charge it from zero. Let it be fully charged before starting it. If you run CWM you can wipe battery state.
Your question is in wrong section in the forum. Try starting the thread in General.
Cheers
+1 this -- and some additional detail...
Wiping battery stats does NOT improve actual battery life. If done properly, and coupled with a calibration cycle, it can increase the accuracy with which your battery reports its current charge. Ideal process is as follows..
Charge to 100%
Reboot into CWM
wipe battery stats under" advanced"
Reboot
Charge back to 100%
Let it DIE (go to 0%) from normal use, DO NOT charge it during the cycle
Re-charge to 100% and you're all recalibrated.
From the sound of it, don't be surprised if your phone sits at 5% for hours. After the calibration, your battery history should be a relatively smooth, downward sloping curve.

Check Settings>Battery Information>Battery Usage and see if a process named RILD is using a high percentage of your battery usage. That process - a very necessary Motorola radio daemon - is wreaking some havoc by causing very rapid battery discharge and also preventing normal charging.
No solution for you but thought I would let you know before you try too many different "solutions" needlessly.
Thanks!

This is not happening for the first time...
Ever since I rooted my device and flashed Android Revolutionary Rom on it, I noticed some weird behavior with my device/battery.
Last night I drained my battery to 6% and I turned it off. This morning I charged my phone with the phone stayed off and when the battery indicator screen lighted up it was showing that 50% juice remains. Since this is not happening for the first time, this time I would like to test on it to see whether there's really this much juice remains. So I turned my phone on and as expected, the battery indicator shows 50++% left. So I play around with it and I noticed the screen flashing terribly after some time. Not long after that the phone hang there and I had to do a hard reset by pulling out the battery. Before that, I can see that the battery is drained to around 20%. I was unable to power it on after pulling out the battery and when I connected my device to the charger, nothing happens (no display, no LED). So I left it there charging and after some time, finally the LED is lighting up (So, I assume that I drained the battery COMPLETELY just now). I can switch on the device afterwards and it shows 6% battery remains. I wonder why is this happening as this only happens when I charge my device with it turning off. Something wrong with the battery? Device? Or I have to do battery calibration?

Let it charge to 100% first before using. Then check how is the battery usage.
There might be an issue with the battery also. If it is swollen then it's time to get a new one.
Try using another battery and see. If it works fine on other battery then your battery needs to change,
The problem could also be in the ROM. Something could have gone wrong during installation even though it may look fine. If this is the case then reflash the ROM with a full wipe. If the problem still remains, return to stock rom and see.
I had the exact same problems, the screen flashes and stutters, network signal is lost and the phone turns off, it is due to uncalibrated battery.
There's a simple fix, download battery calibration from play stor (green android icon with percentage), charge your phone to 100% without using it, then click battery calibr. inside that app, then doscharge it till 0% (do your normal usage as ussual) and then charge it back to 100%
For healthy battery life don't let it drain lower than 10% it's the li-ion physics and always charge it fully, don't charge from 0 to 30-50-60% because the ions in the battery will not have a good flow.
Everything has it's lifespan but if it's configured and used properly it can have a long lifespan
Also to mention, if my recommendation doesn't work, your battery could be swolen due to inproper charging / heavy oc-ing or your charger is messed up.
Also to say, that flickering occured to me when i flashed a new rom and when i do lot of reboots, then the batterystats freak out, the voltages also and also your phone.
Charhe and use it properly, try to stay with a rom at least a couple of days to see how it'll go.

The battery usage is normal, and its not swollen. I guess I will try to calibrate the battery or reflash the ROM again.
