[Q] Captivate Glide battery draining issue?

Within a second my Captivate Glide will suddenly go to 0% power then slowly charge back up over time..or if I charge it, it jumps back up to about where it left off. And it happens pretty much every time I turn my phone on for more then 5 mins. It seems to happen while sending or receiving text? Any ideas what could be causing this or a solution?
I keep my data off, and theres 3 apps (Stock SMS Messenger, Handcent SMS, and the Contacts+ App) that can handle SMS on my phone, and I have locker pro that displays my notifications. And I also use the Nova Launcher, but thats the only app's I keep running. Maybe a conflict with the apps or a bug with one of the apps? I don't see how that'd effect the battery that much but possibly?
I've also changed my ROM a few times, but right now I'm back on the newest ICS update and I've rooted it. Maybe I need to change it again? I can't remember if this problem started happening before I did my last change.
Or maybe just a bad battery? I don't know much about batteries but I haven't had this phone long, I don't think it'd be the battery.
If you have any more questions feel free to ask and I appreciate any help!

I had about the same problem, with it working fine with a decent charge (anywhere between 30-80%), and all of the sudden it would say "battery critically low" and shut down. Putting it on the charger would often get the charge to show what it was before it freaked out.
I noticed that the battery was starting to bulge and get somewhat "mushy"....which told me the battery was probably going to explode or leak if I didn't replace it soon
I have had the phone for a year and four days, and this just showed up in the last few days...fortunately I bought an extended warranty and they will pay for the replacement battery I just picked up today.
FYI, the battery should be totally flat on both sides. Mine would wobble if I set it on a table.

Ok, TL1170, Thanks!
I already narrowed it down to my battery by the time you posted that because I factory reset my phone multiple times and changed the ROM once to see if that'd help, and it didn't..I was running out of stuff to blame it on ..
But yeah, my battery is pretty badly deformed and I just ordered a new one.

Thanks, mine is doing the same thing - about once every 2 days or so. I can see in the battery life plot that it sometimes goes from 90% almost completely vertically to 0% and then right back up to 90%. I don't see any obvious bulges or "mushiness" to it, but it doesn't seem to be completely flat when put on a table. I'll see if I can get a replacement battery, this phone was not used by it's previous owner for maybe a year or so before I bought it, maybe that might have been part of the problem.

Any time a battery is misshaped it can do the oddest things.

Pull out and visually inspect your battery. If there are any visible cracks or bulges, dispose of it carefully. Damaged lithium ion batteries are incredibly dangerous; a properly pissed off LIon will produce a sizable fireball.
If your battery looks fine, fully charge it (until your phone says "100%" or "Charged"), then fully discharge it (don't connect to the charger again until your phone shuts off for lack of power). This is to calibrate the charge estimator chip in the battery itself. Don't bother with batterystats.bin, it's completely unrelated.
If the above doesn't work, you need a new battery. If the new battery behaves the same way, you need a new phone

Happening to us too
It's been happening to my phone for a while now, but I'm usually using it while at a desk so I can keep it charging. However, it just started happening to my wife's Captivate Glide also. I checked my battery and don't notice any bulging or non-flatness... but it happens about once or twice a day now - Pretty much anytime I do anything more than make a call with the battery indicator saying it's somewhere less than maybe 90% charged. I've taken to using a portable backup battery when I'm out.
If you view the battery usage screens, you can see the cliffs where it drops from 80-90% down to zero and right back up. We've only had them for about a year, so I'm going to take it to AT&T and see if they can do anything for it... probably not.

If you're really desperate to get those particular batteries working, you could try cleaning the contacts, both on the battery and in the phone, with rubbing alcohol and Q-tips. But most likely you will need new batteries.

Battery( low power) Shut Down Issue Fixed
I also was having the "critical powerl level" shut down issue over the past two weeks. My phone is about two years old, and there was a few occasions in the past two weeks where i pulled it out of my pocket and it was off. Then this past week the phone (on a full charge) would go anywhere from around 90% sometimes %40, and then all of a sudden say "battery low" and shut off. It would turn back on, but would only stay on for a few minutes.And a few times it also got really hot. It wasnt doing this when plugged into the wall so i examined my battery and there was NO visible flaws or bulging of any kind, it looked fine. But as we all know just because it looks good certainly doesnt mean it is so i odered one on ebay for about $10. It arrived 2-3 days later and instantly fixed my problem. The phone is fine now and hasnt done anything wierd. It was the battery. These batteries have a limited life span, and very often the phone may say the battery is 76% charged but the capacity of the battery under load can still draw it down to 0%. You cant always trust the level the phone says its at. So if anyone else out there is having this power issue it really isnt expensive to find a good battery out there. The one i got was $9.98 and it is a Samsung battery identical to the one that came with the phone. Except the new one has a fresh date of 2013 on it. Very happy to have my phone back. Ive never been a part of any sites like this, but im posting here now because there seems to be a lot of people having this issue, and often someone will put a very complex procedure on these sites to fix an issue when its not always necessary. If you have the power/shut off issue like i've described here and your phone does the same as mine was its probably the battery, and for the price of a new one like i got, its worth trying.

Battery problems and Bricked Phone

Hi,
Had the elephone p8000 for a couple of weeks now and have been very happy with it - updated without problems OTA to the latest stock image, rooted to change the lock screen - but made no other changes to the phone.
Yesterday the battery had run down to approximately 3% - I plugged in to a charger and after about 15 minutes the phone was reporting the battery as 79% full. Which didn't seem correct!
I then used the phone for approximately 10 minutes, after which, without any warning, it suddenly died.
It now won't charge, turn on, or be recognised by a PC.
I've tried charging up overnight - but it still doesn't turn on.
I think whats happened is that the phone has got itself confused over the battery level and then fully discharged the battery to absolute 0 - as it didn't realise it needed to preserve a residual amount of charge.
Anybody got any ideas on how I can rescue this? I've tried all combinations of power, volume +/-.
Would a new battery solve the issue as a last resort?
It's a real pity, as up to then the phone had been great.
Thanks

I have had this type of problem with my old nexus 4 a few times ,phone gone dead no display or charging light,unable to charge using different chargers I had to disconnect battery for a short amount of time
Reconnected battery and everything was charging as expected and phone would power up????? not sure how easy it is to disconnect on P8000 have not had a look at mine
yet

Thanks - I think this maybe the solution. Problem is - having looked at a couple of videos, taking the battery out looks reasonably straightforward - but one of the screws (bottom right hand corner) has a tiny elephone sticker covering it - I assume this is an anti tamper device and will invalidate my warranty (with gearbest).
Not sure if to just give it a go - or spend the cash (£8ish) and send back to gearbest and run the risk of them kicking up problems and refusing to repair. Decisions!
Thanks

Try this:
Press power for around 20s. Release.
Plug charger.
Wait 5minutes.
Press power for around 5s. Release.

Bricked P8000
Hello, I have the same phone and the same problem, i already tried to change for the stock rom, but nothing! My phone doesn't charge or power on, I don't know what else I can do!

Not been able to get it to respond in any way... Have ordered a new battery.
Tried suggestion above but no change...
If you can and it's under warranty I'd try and send back to wherever you got it from.
As a matter of interest did yours show any strange behaviour around charging before it died?
All very annoying!
Thanks

Bricked P8000
How much the battery cost? You will change the battery (by yourself)?

I ordered the battery from Ali express £15 / $22 U.S.
Comes from China so might be a while to arrive.
I was going to change the battery myself - There are some videos online and it looks reasonably straightforward.
However - there is always the risk that the battery wasn't the problem / that I break a ribbon cable / fry the motherboard etc... or something else bad happens - but I thought that (for me) it was worth the risk for the money - this may not be the case for everyone.
Once I get the battery I will repost and let people know if it worked or not...

hello, I have similar problem. Can you tell me did the battery replacement solve the problem?

Hi,
Waited 60 days for the battery to arrive from China and it didn't! Gave up until I saw someone here (in the UK) selling them on ebay so bought one, fitted it to the phone (need to take about 12 screws out and remove the metal plate) and.....
It works! I've reflashed the phone to the Cyanogenmod ROM the guys on this forum have been working on (and it's great work) and am using it as my daily phone without any major issues - I'd even managed to not break the fingerprint scanner (as this needs to be removed to take the battery out).
So yes - a new battery solved my problem - I can't guarantee it will solve yours however - and the battery wasn't that cheap (£20 GBP) but I've got a fully working phone again.
To reiterate the problem I had - the phone suddenly charged really quickly to a high percentage, it then just suddenly died when still showing a reasonable amount of power (probably because the battery %age was not being reported correctly) and wouldn't react in any way. By fitting a new battery after this my phone came back to life in exactly the same state as it had been before. But I can't guarantee it will work for everyone
Good Luck!

Battery replaced, now won't stay on due to temperature.

Hi all,
I have been running my Z1 Compact on 4.4.4 for the longest time, mainly due to sound issues after updating to Lollipop.
Recently, the battery has been dropping randomly from 60 odd percent to 3 or 4 and then shutting down all within a few seconds. The last time it did this, I tried charging it when I got home but the charging light would not stay on, thus it was not charging. All typical signs of battery failure due to age.
Having already replaced the battery successfully on my Z1, I bought a replacement original Sony battery and replaced it. The problem persisted. On first boot, the phone got to the blue waves then black screen, and power off. Charging screen just showed the battery at about 40%.
I risked it and flashed the latest software with Flashtool, having done a complete wipe. The result of this proved no better, but I did get a different message on the charging screen, a message saying the phone had shut down due to overheating. Picture is attached.
The phone is in no way overheating and I've even booted it while sat on a shelf in the fridge to help dissipate any heat generated but with no luck.
So, the old battery maybe did overheat and caused the phone to shut down, I'll accept that as a probability. It may have even damaged something, but I don't think that's likely.
After changing the battery, I would have expected the problem to resolve itself, but it seems like some kind of hardware 'flag' has been raised that is now not allowing the phone to boot in case it overheats again.
Does anyone know of any way to resolve this, reset the 'flag' per se, other than going to Sony? The phone is definitely out of warranty due to its age, never mind me taking the back off lol
It is a shame because it has been a great phone over the years, and I would like to fix it if possible, even if to give it to one of the grandkids. I have my Z3 still (which I won't part with for anything) and I have an XZ too and both are great phones. I would just like to save the XZ1c if I can.
The phone is not, and has never been modified in any way, no rooting, no bootloader unlocking. Only stock roms have ever been flashed, and then only once or twice, to put it back on 4.4.4.
I have tried reflashing just the kernel, or just the system too, to no avail.
In desperation I even left it in the fridge for a few hours in case the temperature sensor was on the fritz, but that did nothing at all.
I just feel like there's nothing actually wrong with the phone, apart from this trigger that won't reset.
Any help greatly appreciated of course.
Thanks,
Mick

Maybe theres lot of consideration:
1. Rom Bugs
2. The Kernel not supported well
3. Battery Issues (But you already change it right)

There are two temperature sensors afaikin our phone. One in the SOC and another one in the battery (hence three pins).
The battery is probably the one giving the high temp report. Try yet another battery.
A bad battery normally heats up very fast inside and the battery temp sensor stops the battery from charging and/or working to protect the phone and the battery.
I changed my battery before when it had symptoms like yours 100-90-0 drop and after replacing with a battery from eBay it was OK. I gave it a full charge then complete discharge and then complete charge to full cycle the battery once and let the phone Guage its full capacity. one year later now my battery is acting funny again (not charging past 30%) and getting so hot when charging it triggers overheat control service in Android.

Any luck?
Apologies for the necro. But did you ever fix this issue, having the same problem

No, I never did figure it out. I've been loathe to spend more money on another battery when I've got other much newer phones. I really have no idea why it would not reset once the battery was replaced, maybe it's the replacement battery.
Have you tried changing the battery?
I've tried flashing different stock roms, Kit Kat, Lollipop, and it doesn't help.
Short of going to Sony, I'm not sure what else to do.

HTC 10 while completely shut down lost 35% battery level in 1 day

While waiting for a replacement SIM card for my HTC 10, I had fully charged it then powered it off. The next day, I wanted to check something on the phone, so I powered it up. The battery level wasn't 100% or in the 90's... it was a shocking 65%.
I've owned 4 different Android cellphones prior to this one. None of them ever exhibited this kind of power drop while shut down. Most lose just a couple of percentage points when in standby. Clearly something is wrong with this phone...
Does anyone know if there's any kind of parasitic drain on the battery of the HTC 10 even while completely off? It's running Oreo. Either this, or the battery is somehow worn out enough that it can't even hold a charge when sitting idle. Any ideas?

Hi, maybe your battery is not so healthy anymore.
Still you can try this:
''Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.''
Supposedly it's the recommended procedure by HTC.

^ Yes, I'm very familiar with that procedure and had done it several times. And then was fully charged after that. And by the way, I said 1 day but it was actually 12 hours later, which is even worse!
I conducted another experiment... with the phone battery level at 77%, I first put it in Airplane mode and then shut it down completely. Well, about 18 hours later, guess what? Battery level showed 76% upon boot up! Remarkable. If the phone is SHUT DOWN, I can't understand how there would be any possible parasitic drain difference between normal mode and airplane mode. There should be NOTHING running. Or, instead of parasitic, this may just be happenstance of what cells inside the battery itself were taxed. I'll have to try this again from 100% charge, just to be sure.

I have what may be a similar problem , I charge phone to 100% let it sit , it drops to 43% when I pick it up it reboot and continues to reboot, boot recovery now it shows 1%, plugin phone boot up and it shows 43%.

I think that when you charge it to 100%, it's not really 100%. The phone may be displaying that figure, but the battery isn't fully charged. And if your battery has suffered deep discharge a number of times, it could have a very diminished mAh capacity at this point. This is why the phone continues to reboot. The operating system starts and it thinks there's enough power to start up, but the battery is actually down to 1%, so the battery protection circuitry kicks in and forces a shut down. The operating system doesn't register this as a normal shutdown, so it goes into reboot mode. And thus, pattern keeps repeating until you plug in the phone to a power source.

Well, I did another test. I charged the phone up to 100%, put it in airplane mode, and then shut it down. A little over 12 hours later, I turned it on and battery level showed 98%. That was curious. Did airplane mode really make a difference? Didn't make sense... until I decided to reboot the phone, just to be sure. And guess what it showed after that? 61%. So my theory was right -- there is no parasitic drain really. It's the battery having some kind of problem. I rebooted again... 59%. Rebooted again 59%. Then I held down all 3 buttons for 5 cycles and rebooted. 59%. So that is actual.
When I charged up the phone, I had done the 3 button hold-down a couple of times and recharged until rebooting stayed in the upper 90 percent. So, the phone most definitely should have been fully charged. This battery is damaged... and given what I learned from the previous owner, who simply never let it drop down below 50% (always recharged when between 50~60%), and pristine external condition, this is just a prime example of the substandard battery and/or battery management firmware.

I experienced something like that last week, where I left it in airplane mode for like 8 hours. I went out did things, came back later and it was litterly being reported at the same thing. Like 68%. It was really weird. Then I had started using the device for like an hour. And it only dropped like 1 or 2%. It was the exact opposite of what we are used to seeing. I was doing youtube, playing a game. Not normal. Then finally the drainage started up again.
Today the device dropped pretty quick to around 35% so I plugged it in to charge. Came back like 15 minutes later and it was reported around 69%. I thought that was way too quick for 15 minutes. Granted it was a quick charge 2 charger, but still, I've never seen that quick of a charge on the 10 or my V20.
I'm really at a loss what to think as far as calibration, what the battery is telling us. I'm thinking of unlocking, throwing on Leedroid and Elemental kernel. I just don't have the time to go through all that yet. Glad I have my backup phones.
My 10 is also like yours in pristine condition. Granted I didn't ask how the seller how tye used the battery before me, but I also never researched problems with the 10 before buying. I was under the assumption since I've been an HTC customer from the M7 and M8, that the 10 would also have a good battery. Same or maybe better than my V20. Especially since they both use the 820 chipset. I guess I'm paying for my ignorance now.

Same as you... great value from HTC phones up until the HTC 10 (having skipped the M9).
I'm in a pre-return mode right now with the seller. She has given me the OK to do a return. But I'm going to see if she might welcome the opportunity to do a partial refund. Because if she takes back the phone I don't know if she's going to try reselling it or give it to a family member to deal with. It's a hassle selling a phone that has problems. My thought is, if I can work out a good price (like half the cost of a typical charge--got two quotes for $140 and $150), I'll go ahead and try to do the battery change myself. But then... I'm a little unsure about jumping down that rabbit hole. It may work fine, but I usually keep a new (to me) phone for at least 2 years. If I'm having battery trouble 12 months from now, I'll be pretty PO'ed at myself. I've already wasted too much time on this debacle.
The other option is going with a Google Pixel. I'm frustrated, because I missed that recent Woot! deal on the Google Pixel that ran a few days ago. They all sold off in less than a day. Refurbished Pixel phones with 32Gb ($200) and 128Gb ($244) sizes. I'd have sprung for the 128Gb. But the Pixel isn't free of issues. There's a dreaded screen burn-in that happens on some models. Unpredictable. And when it does, it's a PITA to replace the screen, almost as bad as the HTC 10.
Lastly... I might just say screw-it and stick with my M8 for the next couple of years, until 5G phones with solid electrolyte lithium batteries are available. Phone companies are starting to do customers a disservice with this "sealed in" battery fiasco. Next thing you know, they'll be revoking the Micro SD memory card slot, like Apple.

Yeah, I'm thinking to hold on to the device. Thought same that I'd try to sell it, but a hassle. Plus I'm still not convinced its hardware yet. I still kind of feel like its something to do with latest Oreo firmware. Possibly Nougat as well. I'm starting to research downgrading via S-on to Nougat or Marshmallow and just leave it that way if the battery returns somewhat normal. While its a pain to do downgrade, its something I'd consider when I have more time. However, if this was my only device, or main device, then I'd probably cut my losses with it.
Tell you one thing, certainly makes me appreciate the M8 much more than i did!

Marshmallow has been a decent version of the Android O/S. You can really spruce it up nicely with different themes. I recently revised the theme on my M8 and it's super. It's just a very dependable phone. And when you get used to that, it's a shock to run into the mess of other phones. Pretty stunned to see all the troubles that the Pixel encountered. Apparently the Pixel-2 has some pretty serious challenges as well, like screen burn-in. I'd never even thought of rolling an HTC 10 back to Marshmallow. Is that really possible? It may not be necessary... as it could all come down to the kernel Go S-OFF and load up a replacement like ElementalX.
So I did a complete factory reset on the phone as I prepped it for returning to the seller. What a pain in the butt... having to wait for the initialization. Took over an hour to complete. Anyway, I made the mistake after initialization and before configuring an account to do the 3-button power cycle. Apparently that wipes all preparation cache, so it had to go through it yet again. After that, I did the cycling 3 times from 99% and it dropped only 1% each time. Baffling. I rebooted several times after that, expecting to see a repeat of that 35~40% drop. Stayed in the high 90's. So with that mystical "recovery" I ran the HTC battery test... and it did just as poorly as before. Definitely something out of whack between the O/S and battery.
I really wish there was a definitive explanation for this. If battery replacement was guaranteed to eliminate it, then I'd feel more comfortable going with a battery change. Would just hate to get burned 12 months later, finding the same issue repeat.

You can, also flash a kernel..... WITHOUT being s-off, s-off has never been needed to change kernel. Please elaborate and stop giving false info.
Thank you.

Marshmallow has been a decent version of the Android O/S. You can really spruce it up nicely with different themes. I recently revised the theme on my M8 and it's super.

Looks like you can downgrade to Nougat or Marshmallow based on this thread here. Can do it remaining S-On.

It wasn't my intention to give false info. I had the impression from what I'd read that making changes at that level required it. But you've obviously got a tremendous amount of experience so I'll revise my understanding. Thank you.

HTC 10 Won't Boot After Battery Calibration - Replace Battery?

So, I bought my HTC 10 sometime last week and I love it, I got the red 2PS6500 version. I have been excited to see people like Leedroid and Faygi working to make this phone so amazing. But I always had a rough battery experience.
At first, symptom was fast draining. It rarely got 3-4hrs SoT, but some days I had good battery life. More recently, I noticed that when using my camera around the 20-30% range, the phone would shut down, and I'd see that it was at 0%-1% and not booting.....
From my research here, this seems like I could try to re-calibrate my battery. I had it charge (powered off) for 2 minutes, then I held both volume buttons + power while still charging. I then let it go up to 100%. When I turned it on, the percent showed 70%. So while it was on, I let it go to 100%. After that, I unplugged it, and rebooted it. It went down to 70% again. I repeated the full charge to reboot. This time, I was 99%. I wanted to reboot once more, just to close the gap from 99% and 100%. USB connection is clean and good, cable works on other phones.
Then the phone just stopped working. It no longer boots up, no LED's, no vibration, buttons don't function no matter the combination. I tried connecting it to my PC and I get nothing recognized. Cannot get the screen on at all.
So I am guessing two things:
(1) Battery might have fired and the connection to the board is gone. I might have bought one that already had issues and this was the last leg of it.
(2) Motherboard damage from the battery? This is something I'm afraid of if I go and replace the battery and I still have issues with it not turning on.
I was hoping anyone with experience might be able to confirm anything I mentioned with the battery issue, and if replacing it solved that.
TL;DR, HTC 10 no longer powers on, shows no sign of life. Battery previously had calibration issues. Should I replace the battery, and then it will turn on, or could there be further damage. Most situations I found were from users that were still able to turn on their HTC 10.

I've replaced my battery recently. I had the same deal. I had to use the actual charger plugged in for a while and it eventually came on

Thank you for responding. My issue/question was more about "if" i replace the battery, will it solve my issue. I have not replaced it yet, and I ordered an OEM battery in hopes that should fix my issue. So hopefully a new battery will allow me to boot up my HTC 10 again.
At least I still have my HTC m8, and I'm replacing it's battery too (swelling and making the screen bulge). The community around the M8 is still strong and there is even the latest RR pie available too.

I gotcha. Sorry I have a terrible habit of skimming and then assuming. Mine was similar but not exact. I was always able to get it to show life after it was on charge for a while.
When I replaced the screen once, i forgot to unplug the battery from the board before I started. I got it all back together and it wouldn't turn on. It wouldn't show that it was charging. So I went in and unplugged the battery and plugged it back in. It acted after like it never happened.

I hope after I replace the battery, it finally boots up. I had to order a new heat blower because mine broke. I'm surprised after I charged it to 100%, it hard bricked and died. I have a feeling th battery was the culprit, since it was always bad at holding a charge....and even more oddly enough, using RR pie on my HTC M8 is FASTER than it was using RR pie on the HTC 10. That battery was very likely affecting my overall experience.

Please do update us with your progress and conclusion. It might help the next person

DEFINITELY. I hope nobody has the issue I am facing at the moment.

UPDATE
So I replaced the battery, was very easy to do with patience and the right tools.
AND, it did not fix my issue. As I opened the phone, I noticed stickers on the chips from a company that apparently did work on it prior to me buying it, and the work they did was bad. I think it is safe to say that the motherboard has suffered severe EDP damage, and it would not be worth the cost to fix it. Burnt pins near almost every chip.... It was so happy being a part of this awesome group, working on the HTC 10 and having Fagyi making the amazing Pie roms. I will be selling my HTC 10 for parts on Ebay if anyone is interested (1 new battery, 1 lcd screen in excellent condition, both cameras, charging ports. . . basically everything but the motherboard that is dead)
So, I am torn between three options. Since my HTC m8 is fixed (top third inch of touchscreen no longer works with tough), I can keep the HTC m8 until it dies and replace it's digitizer/LCD. I can buy another HTC 10 and hope it will not be a crappy one, or I can save and get the HTC u11 (that red color looks so nice!) or go for a Samsung Note 4. I've had the M8 for about 5 years now and it's running RR-P like a brand new phone. I am so sad my 10 just died like that. I was so spoiled with the HTC 10, it was the best phone I ever had. I'd love to have a new device with tons of potential for modding in the future.
Any recommendations then: any device will be modded like crazy, especially with RR or LOS
- keep M8 / replace LCD+Digitizer
- buy HTC 10
- buy HTC U11
- buy Note 4
