Hi everyone!
About two days ago I decided to switch off my ACER Liquid Z3 after charging the battery to 100%. Now I am not able to switch the phone on in the first instance and when I use the AC adapter to start the phone, the battery shows 1% battery.
The strange thing is that when I leave the phone on overnight (8 hours), the battery only discharges by about 2%. So, assuming the discharge is constant, after two days the battery should be at about 88%.
The other thing to note is that I did a 'update' on this phone before switching it off. But this does not tell me if the update is causing the problem because I did not do this 2-day discharge test before the 'phone update'. Also, the phone is running on Android 4.2.2.
Another interesting observation is that when the phone is plugged into a power source, the cpu locks onto the highest frequency (~1000 Mhz) and when you disconnect the power source, the cpu frequency drops and stays at around ~598Mhz
Is anyone else with this phone having the same issues? If so, has anyone resolved it? I know other phones have experienced this issue in the past.
I have not noticed this issue. Generally when on my phone drops 1% over night.
I did try to use the power scheduler to turn it off at night. It turns the phone off but does not turn it back on! Interestingly if the phone is off the alarm works, but the damn thing will not come back on when scheduled.
So in the one test I have done I have not noticed significant battery drain when the power is off. Maybe its because the battery is new. Is it any better now?
-S.

i am having a quite unusual problem with the battery on my TP. it is hard to explain but i will try my best to do so. While i was casually surfing the web while on the charger i noticed that my battery started to drain ( this is the more ordinary problem that has been posted on many threads ) but this new situation is. The indicator lights and meters within the TP indicate that the battery is charging yet it still drains. I tried turning it completely off and removing the battery and then putting it back in and charge the unit for one hour. After one hour it charged to 20% which is reasonable enough for normal use, so i turn it back on and continue to use the device again the TP still indicates that the battery is charging after listening to about 7 songs i get a very low battery indicator warning (at the same time the battery indicates its charging) there is NO overheating and when the battery reaches 0% it does not die the screen just goes off and i can turn it back on and still recieve the low battery warning but what i cannot do is use data or even turn the phone radio back on. I am on the NFS 1.05 ROM, any suggestions?

Try to get a charger with an output of at least 1 A. It could be that your charger is not powerful enough to compensate for the drainage. The other thing is that WM' battery indicator flat out sucks... it is like Windows file system when it is desperately trying to tell you how much time you have left before your task is done (2 minutes jumping to 15 seconds jumping to 54 minutes jumping to 2 seconds jumping to 3 days, etc)..
Flash to another rom and see if the behavior still remains.... I doubt NFS messed up that badly with power settings, but it is always worth giving it a shot.
yea i doubt its the rom either as i was having overheating/drainage problems on stock but it wasnt anything like this
Hi guys,
Have you experienced mysterious battery drop between turn on and turn offs?
for example, one time when you turn off your tablet and the battery level is 50%. The next time when you turn it on, the battery level becomes 40% (maybe not this much, but maybe 6% - 7%) This problem has occured ever since I have gotten the tablet about two months ago. This caused me to have to charge the tablet without much use. I do not abuse the tablet and I only use it normally. The turn offs are full shut down, not idle. I have been using Flashback honeycomb firmware. But I think initially I had this issue when using illuminate at first too.
is this a common issue or just the battery indicator/firmware is not right?
Thanks.
Hey Everyone,
I apologize if this is a repost. I know I read somewhere (I believe here) about a similar issue, but I couldn't find it in searching.
A little background - AT&T SGS2 running stock rom (2.3.4), rooted, using a custom kernel (2.6.35.6) I got off of here.
Anyway, my phone has been working great for months. All of a sudden, my battery indicator is completely wacky and innacurate. It seems to have started after I came back from a trip and had to put it in 'airplane mode' a few times.
The battery level indicator goes down very quickly, and is not a true indication of my phone's charge level. I noticed it a couple days ago (after we came back) where after about 6 hours, I was down to 40%. Normally after a full day's usage I am still at ~80% by the time I get home from work. Since my phone had been running for weeks without a reboot, I decided to reboot it, thinking maybe I had some overzealous background processes running. It came back online with the battery indicator at 8% (down from 40% a minute prior)! After about 30mins or so, it began to go up, and settled around 14%. It stayed at this level for hours, until I plugged it in when I went to bed.
The next morning, same thing, it would lose 1-2% every few minutes until it got down to <10%, where I would get a warning about a low battery level. But once it hit that mark, it would stay there for hours and my phone would work perfectly fine.
As I mentioend above, I thought I read a similar story where the recommendation was to turn the phone off, charge it up all the way, and then turn it back on after it was fully charged. I tried that last night, but my phone is down to 87% after only 2 hours of non-use.
I've made sure that UV/OC'ing was disabled, that no background apps are doing anything weird, etc. And it's not like my battery is really dying quickly - it's just that Android thinks it is. I've checked the level using multiple programs, and all report the same incorrect information.
Does anyone have any suggestions on how to fix it? Thanks!
You have encountered two separate issues, one of which is widely documented (fuel gauge reaction to rebooting), one of which is unexpected but possible on UCKH7 (abnormal drain).
But it doesn't look like the battery is really draining that much quicker, only that it's showing that it is. For example, while it might take me only 3 hours to go from 100%-10%, I'll stay at 10% for hours.
It's like the battery is no longer calibrated properly.
Do you use Samsung original charger? If not, try. It should go away.
Take your battery out for a few minutes. The SG2 differs in that it uses a chip for battery calibration/stats. You need to cut power to it completely to reset it. Now, if it still does it afterward, either the battery is faulty, or the phone's ability to measure voltages is wonky.
Also, are you using the phone's Power Saving mode? Maybe the battery is dying but the phone is taking steps to make it last longer?

I used to never use my Samsung charger and never had issues. However, months of using my blackberry charger has rendered it now ineffective. The charger dongle was slightly smaller, and its continuous wiggling messed up my phone's power port slightly. It's a good thing that my Samsung charger still works.
When we were on vacation, I was using my wife's charger for her phone (T-Mobile G2x) so we didn't need to take two (seemingly) identical chargers with us. My understanding was that the pinout and voltage were all the same, so I didn't think it would matter. Maybe that had an impact?
Normally I use my Samsung charger, and have been since we got back.
I haven't tried removing the battery yet, since its in a hard shell case and was hoping I could resolve the issue without taking it apart. But I'll try that tonight.
Power saving mode is disabled. I've also disabled BT, Wi-Fi, GPS, and shut down every app. In the time since my first post (84%) and now, I'm down to 58%, and my phone has been sitting on my desk unused the entire time.
According to the built in battery monitor, Android OS accounts for 92% of battery usage, with Display at 3%, Cell Standby at 3% and Phone Idle at 2%.
As I mentioned above, I thought I read something about a 'trick' to reset the battery gauge by turning the phone off, charging it to 100%, unplugging it, and then turning it back on. Was I mistaken?
Thanks for the responses.
FYI - I just pulled the battery, let it sit for a minute, and plugged it back in.
Battery level went from 58% to 39% after it powered back on.
I'll try charging it again to see if it has any noticeable impact.
Oh, I did want to mention that I've been very religious when it comes to charging my phone properly and trying to "take care" of the battery. I never let it get below 20% (outside of recently due to the issue), I always charge it up to 100%, I never do quick "let me just charge it for 15 minutes to make a call" type charges, I always use a wall charger and not a car charger, etc.
Down to 38% during the time it took me to type this...

That to me sounds like you might have an app creating a wakelock and preventing it from going into deep sleep.

With the exception of high load immediately following a reset (which is why it goes funky on a low-battery reboot), it's basically impossible for the fuel gauge to go out of calibration. It's designed to continuously converge towards truth.
Check the raw battery voltage when it seems to be funny. If your voltage is consistently low, you might be experiencing a hardware failure (like maybe the battery's protection circuit is on its way out.)
After pulling the battery, putting it back in and recharging it, it seems to be working well now. Too early to say for sure, but I went the entire afternoon and evening (up until now) with some mild usage, and am only at 84%. So far so good!

The phone has a voltage drop which causes the drop from 58 to 39 when you reboot it. I'm not a fan of it either.
I have an Atrix 4G running Neutrino 2.9 EE, with a new battery I bought only a few weeks ago because I thought my old battery was dying. But I'm having the same problem with this one. I can't get it to charge past 70% or so, and the charge seems to drain very quickly, about 1% every 15-20 minutes. I checked the battery usage, and Phone Idle is taking up around 60-70%. I've got wifi off, the screen turns off after one minute, and the brightness on half. I'm really at a loss as to what's causing this, so any help would be great.

Try to use all battery till your phone turn off, when charging again go to recovery and clean battery stats, rebbot and charge to full battery, see if your bar go to %100, i install battery widget and have an option for motorola phones, enable that option, that help me a lot,
Good luck!!!:fingers-crossed:

Battery drain issues, it seems, are as varied as "My car is making a noise that goes like this: ____"
Do you have the battery calibration app off the market? A full charge is 4200 mV (or really close to that value), regardless of what percentage your phone is displaying.
If your phone is getting up above 4100 mV, then the battery is fine. You can trick the phone back into displaying a more accurate percentage for a while, but it's not permanent:
- Charge the phone as high as it will go
- Shut the thing off and pull the battery
- Plug in the phone, wait for the question-mark icon to appear
- Re-insert the battery, let it sit for a few minutes (10? 20? no magical number here)
- Turn the phone back on. Percentage should be a lot closer to 100%.
If you're getting a decent charge but the battery is genuinely draining quickly, well... all I can offer is my experience from this summer. My major symptoms were:
- Losing an entire charge in the course of 8-9 hours, but ONLY when wifi/mobile data were turned on
- *Extreme* phone lag when wifi/mobile data turned on. Every single app would force close. Not fun at all.
- Checked what's using the battery, and "Contacts" was responsible for ~5% of the charge.
After six weeks of debugging hell, wiping, reflashing stock, etc I found out my contacts were nonstop-syncing (and duplicating, and duplicating, like rabbit offspring) on one particular email account. Killed the email account, got a functional phone back. Battery life returned to normal. All that to say, one misbehaving app (even a stock misbehaving app) can trash the phone's performance.
If you can stand it, try returning to something completely stock and not restoring any of your apps/data for a few days.
Hello, I've started having some weird battery issues with my HTC One X+, wonder if anybody else has seen this before. I've attached a screenshot of the battery graph for my phone, so you can see what I've been encountering.
It all started two days ago, when my phone charged down and shut off, despite being idle and connected to my laptop for USB charging the whole time. Since then, I've been seeing all kinds of wacky behavior with the battery stats. The status has been stuck on "11M 19S ON BATTERY" for the last three days. It discharges really fast even when idle, which it wasn't doing before. Last night, the battery chart shows the phone either being awake or with the screen on, but it is wrong: the phone was turned off.
I turned it off almost all of today, turning it on maybe 2-3 times just to check the charge and then immediately turning it off, and connected it to AC charging the whole time, but the battery charge seems to go up and down during that period! At this point, my battery stats seem completely corrupted, except for the fact that the phone does shut itself off when the charge goes to zero, so the total charge may be correct.
I'm not sure if this is a software issue or hardware, as I seem to be getting strange data from the software. I looked at many of the battery threads in this forum: they say to charge the phone to green and discharge a couple times, but I cannot get it to go to green again, even with the phone turned off and AC charging! I should still be covered by the 1-year manufacturer warranty: do I need to send it in for repair or this is some known software issue that I can fix myself? I'm running stock unrooted Android 4.2.2 Sense 5 on the international unlocked HOX+.

I thought I'd update with the latest. After a couple days of freaky battery behavior, I was finally able to get the HOX+ fully charged again, after which the problems went away, still no idea what caused it in the first place. I wanted to make sure it really went away before posting: it hasn't recurred in the weeks since.
I fell asleep last night with a podcast playing on my HOX+ at the lowest volume setting and held next to my ear, woke up this morning with only 50% battery used after 12 hours of almost continuous mp3 playback. I've always been impressed with how little battery this device uses while playing mp3s, still going strong. :victory:
Sigh, spoke too soon, it's constantly discharging again, no rhyme or reason why, and the charger can't keep up. The weirdest part as always is that it can't even recharge while turned off, implying there's a short circuit or something else wrong with the hardware. I'll see if I can get it to charge eventually, may have to turn it over to HTC this time.
