ANS UL40 battery issue -randomly goes to 0% and powers down - Android Q&A, Help & Troubleshooting

Phone is a ANS UL40 running 7.1.1
Battery will randomly go from partial charge to 0%.
This just started happening after having the phone about 6 months.
If I leave the phone unplugged overnight, it will be dead by morning (this is a new thing, it holds a charge pretty well). Doesn't have to be overnight either, could be just a half hour or something. The battery just dies randomly.
Even if I do have the phone plugged in and have the screen on (watching a youtube stream) it will randomly go to 0% and self shutdown.
Stock battery which seems to be stuck inside the phone. It doesn't seem to come out, I don't know if it's glued in or what.

Its actually removable -

I have the same issue with mine and I just received it as a replacement phone about 3 months ago. If anyone has a clue as to what to do please share. Been to all the blog pages and customer pages related to this model and it seems to be a recurring issue and so is overheating and a dozen other things. What the point in having Lifeline when all the phones that they give or sell don't work.

And I thought it was just me. Needing a lifeline phone seems to mean we get the worst of the worst devices. I had to pay extra for the UL40 because the "free" phone was useless. The UL40 is near useless, and this battery issue makes it unreliable.

i have the UL40 and requested a replacement phone (because of unsustainable malware issues that survived a factory reset) and the L50 they sent me had this issue. i couldn't find a solution and had to request another replacement.
oddly, i occasionally experienced an apparent battery discharge (phone powers off, needs to be connected to power to boot up again) but when it powered back on the battery was at ~65%, clearly plenty of power.
my completely uneducated guess is that the battery terminals in some of these phones are loose, either causing the battery to discharge completely or simply disconnect momentarily, resulting in the phone losing power.

Battery issues part 2

So the original battery in my phone.. well... sucked. When I pulled the phone off the charger it would jump down to 93% no matter how long it was on the charger etc. Any attempt to bump charge was thwarted in the fact that I cant charge the phone when its off (it automatically turns on and boots into CWM). Wiping the battery stats when the battery read 100% in the OS would still result in the above.
So I ordered that 1600mah battery from Seidio. Ran the charge out of it yesterday and charged it to full during the evening/night. Wake up this morning, pull the charger out of the phone, and BOOM 100% power. Not 93%...
So was it my old battery that was bad or was there something wrong with how the phone saw its power rating?
From what I've seen with the phone, it drops down to 90% or so before it starts charging again, but it won't ever have the display show a battery decrease while plugged in.

Right but I can watch the meter go all the way to 100%... pull the plug and it goes down to 93% within seconds.
funny thing phone did the same thing...took it off the charger this morn and it dropped down to 95
I'm at 99% after about 2.5hrs of mostly idle usage. I've been just rebooting the phone with it on the charger in the morning, give it about 15-20 minutes and usually it'll stick at 100

All you are doing is semi-bumb charging it, which is fine if you really must have that extra 1hour of battery, but be warned, doing it constantly will damage your battery over time. that is the reason the phone has built in charging/decharge in the first place.
The reality is if your phone is sitting idle, that 5% wont matter at all once your phone attunes to your battery, and if your using the phone so heavily that your going dead long before the day is done (after attunement) then the 5% still wont matter !
i was having the same issues - 90% right after unplugging. had to charge the phone 3 times in ONE day and i never even touched the phone the whole day except to check the battery percentage.
brought it into verizon, they gave me a new battery and now it lasts me the entire day. when i pull the plug out now, it drops steadily like a normal battery should. i tried bump charging before i brought it in and it didn't help at all
The same thing has been happening to my dads Thunderbolt.
He charged it overnight, took it to work and was losing about 1% per minute without touching the phone. The only time it was touched was about 1 timer per hour to take down the battery percentage for his log.
He took it to the verizon store and they told him he should not expect anything longer than 4 hours of battery life without touching the phone..what kind of BS is that?

I'm having the exact opposite problem with the batteries--just ordered two of the 1600 Seidios that delivered yesterday and even after running pretty much down, fully charging overnite with the T-bolt powered down, drops to 95% immediately. Conversely, the OEM battery would stay at 100% for hours if the phone was idle (screen off / receiving any emails and SMS). Go figger.
There is a post in the Android Central forums on the 1600 battery compared to stock. After testing, they found that the two perform almost identically. Basically, it isn't worth replacing unless you go with the big HTC extended battery. Although having a spare isn't a bad idea. If only that battery door wasn't so tough to pry off when you need to change it...
nexus s had the same problem its nothing big though

Most of us probably won't have the phones long enough to see any possible damage. Starting off at a full 100% is a lot better than immediately dropping to 95 or so after pulling it off charger. It's kind of like the gas gauge in my truck. Stays full a while but once it moves off of full you can watch it drop. lol

[Q] Battery

Hello
Last week i bought the phone, and used it till the phone battery was empty. I tried to recharge the phone, but i wouldn't go on, only the red light blinking. I had the phone charged for 2 days, with the og charger, no result. Looked like the phone was dead.
Today i tried it again, still no result. All of a sudden the phone turned on and was charging. It is now on 99% and working just fine
Should i contact HTC?
I'd see if it happens again if you let it drain again.
If so, take it back to the store, they will give you a new phone if you can reproduce the problem there.
I have also experienced this issue when letting the battery go till the phone shuts down. I usually have to just unplug the charger and then it will boot up again.....but if i don't unplug it will not turn on and just blinks red.....
One night I fell asleep doing a nandroid back up (Yes I flash till I drop), I had the phone on the charger while doing so. I woke up 6 hours later, was still in recovery and with the battery fully charged.
What does this have to do with the op? Nothing, but I thought it was pretty cool.
I see these stories all the time, STOP DOING IT!!!!!!! You aren't suppose to drain batteries till there completely empty. You are doing damage to your battery when you do this. The battery has built in protection circuits and when you completely drain the battery the protection circuits can't operate. This may be the cause of the battery failing to recharge after a complete drain. That is why resetting the battery by unplugging the charger or removing the battery and reinserting usually works. I don't understand why you would ever need to use the phone till it shuts off. If that's the case bring the damn charger with you or invest in a second battery.

It happens when you can't find a charger, sometimes you don't think you'll be out as long, and end up in a dead zone, BAM dead battery.

Well me i am always running around in the streetz. With my Evo 4g i would walk around with 2 extended batterys and 2 regular HTc red batterys. I am a heavy user texting, phone calls, internet all day long. and some times i leave the house at 9. a.m. and don't get home till like 1.a.m the next morning. i will be getting that 4000 mah battery shortly.
I have a problem where if the phone is off and charging, it wont turn on. I have to unplug it, turn it on, and then replug it.

Battery No Longer Calibrating Properly

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.

[Q] HTC Evo 3d - Battery charge indicator after drop.

My appologies if this question has been answered somewhere else, I could not find any other threads with a similar situation.
My phone was dropped and ever since then it has not shown me the right battery level. It will charge on USB or AC up to 99% and stop. I connected it to AC power 30 hours ago and it never gave me the green light. This is after a full drain and then recharge. It did however stop charging at some point. I noticed no light was on, red or green, turned on the phone and my battery had gone from 99% to 41% in 22 minutes. I plugged it into USB and it appears to be charging back up. My widget now shows 84% with 4334mV (i dont know if this is right or not).
It is not an issue with the battery. My wife has the same phone and I swapped batteries. Mine works fine in her phone and I have the same problem with hers.
My other issue is that when I use the phone off the charger it will not show me the level accurately when it is draining battery. Example being, I unplug the phone at 99%, within 5 minutes I'm down to 92% (i know this is not unusual because of how the batteries charge). But, I will stay at 92% for hours and hours, with moderate use of internet, phone, and apps. Then it will fall from 92 to 60 ish in a few minutes and do the same thing. Sometimes it will tell me that I'm getting low (under 15%) other times it just turns off a second or two after the notification. If I plug in the phone and turn it on it shows me 1% and charges up to 99%.
In the few minutes I have been typing my phone charged up to 91% with 4336mV.
I was running ViperRom ICS when the issue started. Restored it back to Stock with no root and the issue remained. Now I am running Mean Rom ICS with the same issues.
I have cleared the battery cache in recovery too.
Any help would be appreciated.
If you kiss it. your phone will love you and it'll be all better. NOW KISS IT AND TELL YOUR PHONE YOU'RE SORRY FOR DROPPING IT! LOL!
Based on my experience with batteries of all kinds, it sounds like one of the cells may be damaged. Best bet is to get a new battery. They are decently cheap for a good one. Im actually looking for an extended unit myself. If you come across one, please PM me.
Thanks
That was my first thought but when I swap my battery with my wife's battery I have the same problem. Both batteries work fine in her phone but not in mine.
Sorry to bring this up again, my bad. But seriously you are not the only one with this issue.. I had the same problem since stock, swap battery didn't help either.

Battery randomly charging or discharging

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.
