Universal suddenly shuts down; battery or other problem?

I recently acquired a HTC Universal for dirt cheap, and have found the first problem to explain the low price: Whenever I'm using a "power-hungry" application (TCPMP, Internet via Wi-Fi) it eventually just blacks out. Full shutdown without warning.
When trying to reactivate the unit, it reboots as if after a soft reset.
In fact, if I try to reactivate it too quickly, even the reboot fails.
None of the above happens when on external power.
This leads me to think that it's nothing worse than a battery that's lost its mojo, but since there is no warning about low battery, and when the reboot finishes successfully even SPB says the battery is somewhere around 70%, I want to run this by you guys.
What do you think? Just go get a new battery, or is there something else going on which will make buying a new battery just a waste of money?

I'd say it's the battery, 99% sure.
I'ts gotten old and its voltage breaks down under load. If you have proper equipment and a glimpse of an idea what you're doing you should drain about 300mA from the battery and measure its output voltage.
You'll most likely see it going below 3.0V quickly.

I'm afraid I don't have that equipment, but all I really needed to hear was that it's probably the battery.
Now I can stop thinking about it and just order a new batery.

Unexpected reboot - Apparently bettery issue
Hey Holybear, my device shows exactly same symptom, If possible let us know if bat replacement solved the issue>

I knew I wasn't the only one withthat problem. I think i've prooved it to be a battery faultt. as if you taake te battery out after it gets to that stage where you just can not get it too complete a boot up without it shuttinng down again
take out battery ,place finer oveer all battery trmminals and plug inn your mainss charger it should now boot up and runn fin off the charger unless your finger slips off the battery terminals. thisshsowws it's the temprature sensor in the battery.
I posted a more in depth reply to a guy in the wm6 threads as wifi heeaating up battery wass shutting off his device as well

@ cyberjak
Hmm, the idea that a temperature sensor in the battery causes this problems is interesting. I'd just expect the device not being cappable of rebooting instantly, because there should be a hysteresis implemented in the battery's protection circuit.
I had the exact same problems and described them elsewhere, but in my case it surely wasn't an issue of temperature.
I'd suggest to take out the battery and wait about an hour for the device and the battery to cool off. Most likely the battery will then take a complete boot but shut down soon after that - without having gotten near to "warm" yet.
If this happens you can be sure that the battery itself is dead without needing to measure anything.

Okay, to tell you what I tried:
I ran the Universal until it spontaneously went dead.
Started bootlaoder to see how much longer it would work on that. Was a bit longer, what with low energy consumption, but soon even that wouldn't stay on for long.
Then decided to try the "old wives' tale" (meaning I don't know whether there's any sense behind it or not) of putting the battery in the freezer for a little while.
When I took it out and let it get back to normal temp, I plugged it in and after a while booted the Universal. It showed 40% battery, lower than it had ever gotten lately.
Recharged for a full day.
Tried TCPMP: went dead after three minutes.
So in my experience the above didn't help battery performance.
Am going to get a new battery in a few days; I'll keep you posted on progress as I try with a fresh battery.

I had the same problem, whenever i did something cpu intensive, it would just black out.
I just bought a new 3100mAh battery. Best thing i ever did. It might be thicker now with the new battery, but it actually feels more comfortable as a phone. Plus the new battery only cost 13 odd quid, so definately well worth it. Oh and it doubles the battery life (3100/1500 = ~2... duh)
Hope that helps.

oh you know wat i have the same problem with my Jasjar and the bigest problem that there is no batteries on market for Jasjars in my country....its looks like im living in Jurassic Century!!!

If you want i can send you a battery xplayer, they're quite cheap here.

I ordered a regular battery replacement, but maybe I'll add a 3100mAh as well.
I could use it as a media player during long train trips.

I revived two batteries by intense cycling to work quite well again. They still black out at 20%, but only under extreme load (active gsm connection, active wifi, bluetooth and having to render a webpage).
But you should be able to discharge them below 25% at least. Else they're most certainly "too dead" already. And you should do at least 3-4 cycles.
My guess would be that the freezer finished your battery off. I don't understand how this method should work anyway, as lower temperatures reduce the time affected capacity loss. Actually the best place to store a LiPo or LIo battery is the fridge, charged about half the way.
But I also ordered two 3100mAh batteries. I'm using the Uni as a laptop replacement and the permanent wifi usage together with some cpu load and the backlight kicks the battery's ass quite hard.
In Germany the China 3100mAhs are overpriced and it's hard to get your hands on an external charger, but on Ebay.co.uk there's a seller that offers battery and charger as a bundle for about 15€. This will give me a solid 6000+mAh per day and should be enough to forget about virtually every setting related to power consumption
@ xplayer
If you haven't donw already, take a look at Ebay.com, co.uk etc and look if one of the sellers there will ship to kurdistan. You may be lucky

Thanx for helping the guy,yo folks on xda are the best

Just to give you all the end of the story:
I ordered a regular replacement and a 3200 mAh one, and both have returned my Universal to a well-used life.
Thanks again to everyone helping me out here.

For you guys does the device switch off only when the battery is low, or any time. Cause I have this problem as well, and I was SURE that it wasn't a battery problem until I read this thread. The phone switches off intermittently, sometimes after only 3' talk time right after it had been charging for a full 8 hours! Also, usually if I let it sit there for a few hours I could then turn it back on and it would last a full day, so I knew it wasn't due to low battery.
The overheating theory would explain my problem, as, now that I think about it, all my seemingly-random shutdowns were during radio activity (making or receiving calls, especially when the phone was searching for signal, or wifi, which would almost instantly kill it). Strange that it overheats like this, most phone batteries simply run out of charge faster and faster until they can't hold a charge at all, but mine lasts almost as long as it always lasted even though it's 2 years old - unless I get the shutdown thing of course.

I asked this in another thread, but since this one is full of people who got replacement batteries I'll repeat my question here as well:
How much thicker than the standard battery are the 3100 and the 4200mAh ones?

I also got this problem recently, so I bought a new battery and although it's only a 1600mAh battery it runs great again

hey roodkapje ive got that same problem with my battery for my spv m5000 the bad news is that i cant get that batery in barbados so im all out to see

[Q] Strange Battery Issue

Hello everyone, My Note3 (SM900) is acting strangely battery-wise. It has been rooted for over a year and using custom recovery. On the last weekend I did an upgrade to Android L but the issue remains same.
After charging to %100 everything is OK until the battery hits around %70. After that point, while using phone (call or usage) signal meter shows that zero like image(no signal), phone gets freezed for a second or less, shows critical battery warning for just a moment and then it reboots. When it boots up, it says battery is at %0 or %1 and if I leave the phone alone, battery percentage starts to rise up to about where it was reset. By the way, if I try to use the phone after reboot, sometimes it just powers off just like when it does while empty battery.
I tried to reset battery stats according to a xda post but it didn't solved my issue, so I have reinstalled Android L. Issue still remains. I would buy a new battery or send the device to warranty but first I want to make sure it is related to hardware. Also I am not sure if Samsung will say device is unlocked so its out of warranty.
Any help is appriciated.

Flash another rom

That's a dead battery.
If a device shuts down at a decent percentage and then shows low percentage when it turns back on, it's time for a new battery.
Depending on where you're from you probably don't have a warranty on the battery anymore anyway, (It's mostly 6 months or a year), and it's easier and a whole lot cheaper to order a fresh battery than send your phone in for 2 weeks and deal with Samsung's KNOX policy and the mandatory research costs of around 70 quid. A new battery is about 25 quid.

If you don't mind the size increase (It about doubles the thickness), the ZeroLemon 10.000mAh is the ultimate way to go. That'll last you a week with intensive use. Thread with links here: http://forum.xda-developers.com/showthread.php?t=2781990
If that's a bit too thick, your best bet is to nose through the Accessories board, there's quite a lot of options (And sadly I don't know them...). http://forum.xda-developers.com/galaxy-note-3/accessories

Battery drops suddenly to zero then in complete charge

I have Note 4 SM-910C Unrooted international on stock ROM 5.0.1.
my problem started with battery charging to around 80% then stops or take like 5 hours to reach 100% then when I use the phone battery suddenly drops from 20-30% to zero.
if I remove the battery then reinstall it reads 16-18% but may drop back to zero.
when turned off while charged it charges to 100% normally
It is irrespective of charger/cable i use (2mA).
tried hard reset and battery calibrate (non-root) but no good.
Any help with this problem

Sounds like your battery has gone rogue so you might wanna buy a new battery. A great example why not to buy Note 5 lol.
Maybe it's a bug in your rom build so why don't you try and upgrade from 5.0.1 to 5.1.1.
I have not used stock roms since the s2 days and after using custom roms I have never looked back.

i have the same problem with my N910F.. at 20% my phone dies.. like today it was 20% dropped to 4% in an instance and then died..
this is happening since upgrading to 5.1.1 (dirty)..
is it possible to fix this with a factory reset ?

Try Battery calibration and battery repair from the store... If it's not doing something, then replace the battery

make sure your battery is fully charged. From dialing interface typing in *#0228# to check battery info and clicked "quick start" at the bottom of the screen, then your battery will drop down quickly, try these steps several times.

Yeah, Samsung has a solution. Buy a new phone as they will never update the 1 year old one even though they ****ed it up...
As much as Iove Note family I am more and more pissed with Samsung and eventually will stop buying their ****.... Already done with their watches by the way...

Definitely a degraded battery problem.
I got a new battery and problem now solved.

I have the same problem and already bought a new battery but the issue continues.

Samsung Note 4 N910C battery drain

Hello and Happy New Year to all,
*
I came across an issue with my Note's (N910C) battery today and I would like your opinion on it.
*
A quick background:
*
The phone has never been rooted.
9-10 months ago I downloaded an official firmware (6.0.1) which I flashed via Odin and it began to drain the battery very fast, killing the phone in less than a day.
I got a new battery, but the problem was still there.
Eventually I tried another firmware which worked nicely and consumption returned to normal levels. Since then, I had no problems whatsoever.
Yesterday night I got a notification to update. I had already done another two in the past - if I'm not mistaken - , without noticeable difference.
I did the update overnight and I removed the charging cable in the morning. It seemed that it was a little warmer than usual, but I did not pay attention.
The battery percentage was reducing at the rate of 1% per minute and it died within 2 hours.
I checked battery info, nothing abnormal.
I have two questions:
*
1. Does anyone have similar experience with this model (or other)?
2. If I reinstall the previous firmware, normally the problem should be fixed, right? I mean it started after an official update which AFAIK affects native apps only.
*
Thank you in advance

I have noticed on my Note 4, after upgrading to marshmallow, the battery drained like crazy too. It would drain 10-20% when I use it for 20 mins or so. The battery that I'm using is a 'new' one that I bought just about a year ago although the problem still occurred when it was fairly new.
I'm speculating that there might be some sort of battery or software issue with marshmallow as the original battery that came with the phone also had the same issue. It would drain fairly quickly until one day it just stopped working and would boot loop until I plugged it in to the charger.
Ever since marshmallow, I have never seen my battery get to 15% before switching off completely. Sometimes even 45% lol.

I had a faulty N910F and got another (used) one and it's had occasional forced closes at between 15-20%. This worries me that it might go the way of the old one where it developed the issues with it freezing and the frequent reboots....does yours exhibit any other issues?

Yes. Unfortunately. Currently, it would just die halfway even when I'm at 50%? That's the highest that I've noticed. So I had to charge it up for a bit maybe to 60% and it would be fine before dying around the 20+ - 40% mark. Previously, the original battery that came with the phone had this weird issue where the battery won't hold any charge even when it's fully charged. Like it will go to a bootloop when I've unplugged it even though it's at 100%. When I bought the new, current battery I noticed that it would still die off at 15-20% and the original battery became bloated a few months later.
Are you using any custom roms? The bootloops and freezing could be related to using some custom roms. I changed from a N7 port to a deodexed stock rom and the frequency of the freezing and reboots just plummeted. Reboots only happening when the battery is close to dying.

Ah right, so you had only the reboots, nothing else? That's fair enough.
No, it's nothing at all to do with the ROM. I'm stock but LOTS of people have had the same issue. As it stands, the only way to fix it is to get a new mobo :crying:

Well besides the usual overheating that's related to our snapdragon CPU, nothing much but mostly battery issues.
Although there is thread that I'm following that promises to fix the 15-20% issue. Checking their method to see if it works or not

I had a similar problem with fast battery drain - did a factory reset and it's back to normal. Make sure you're using a battery from a reputable source like RavPower (don't think there are any genuine Samsung ones left and Anker stopped making them).

Is this battery consumption normal?

Hi all,
I just come with this Screenshots to know your opinion on the consumption of my s5. Honestly Im jealous of those people getting 4,5hours of SOT in a full charge. I believe I can barely achieve 2h. My phone is rooted, de bloated with smart debloater and uses Greenify (which has not provided me a noticeable gain).
I've seen a very big drain just after plugging off the phone (like 5 or 6%) in two hours without using it. Also everything I unlock the phone the drain is very fast. So idle state seems no to be the cause
What are your thoughts? Thanks in advance.
By the way, while writing this post I've lost 5% of charge.

Need a new battery I think and with the battery you gotta keep it cool, don't charge you phone and use it when its under 20 ℅. And the hotter the battery gets the faster it will discharge and if your charging at the same time the CPU will work harder to charge the battery and do whatever you want to do with your phone making it a double whammy wearing out your battery much faster than normal. You not supposed to let our batteries to go below 20 %. Well you can but don't use it at the same time your charging.

Thank you very much for your information. Any suggestion about a new battery? I've seen this one.
I've just plugged off from 100% and I got a battery drain of 5% just by speaking 15 minutes (no hand-free). I think it's a very big battery drain for just a small talk. I think that confirm your hypothesis of the wasted battery.
Is there any way to know the real capacity of the battery I currently have? It is just to know how far it is from its original performance.

I've checked on Go Power Master app and it claims 2520 (at 90%) mah in my battery. Is this confident? If so, I shouldn't expect a big improvement buying a new battery. What about using other roms or making a factory reset?.

How old is your battery? Mah rating and the rate it discharges are different you can discharge 2600 mah batter in an hour or 3 days depending on use and environment and conditions. Like I said before the hotter your battery gets the faster the disharge go same with the cpu the hotter it gets the more power it demands from the battery. And if your battery get under 20% fast charging comes. Into play as well which is bad for the battery as well.
If your dropping off that fast I think is a defective battery or over clocked cpu settings. My s5 did he same till I bought a new battery I last 8-12 hours of heavy use now compared to 4 hours. With a new battery I suggest a higher capacity but same dimensions as the old one they can be expensive but a bigger battery will damage your phone over time.
I have a 5600mah battery now by 5he way.

Oh that battery looks OK I can't read the language lol just make sure its not refurbished or used and check out if u can refund it or not lol

My battery is from October 2015. It's the original one that came with the phone

Here is last report:
Despite performance is not the worst, do you think the difference with a new one is very big?

Back in my S3 Mini days I had to change the battery and the difference was huge for it. A year ago I replaced my S5's battery for the first time (I own my black beauty since february 2015) and I remember that I saw an improvement in battery life and in performance a bit as well.
A trick: take out your battery and put it on a flat surface (table or whatever) and try to spin it. If it spins freely, buy new one for sure.
I'd advise you to also update from KitKat to Marshmallow as that made my phone brand new but I see you're on 6.0.1 already so nevermind
I myself lose the first ~10% of my charge in one hour or even less...while not doing literally anything with my screen off. So yeah, maybe it's gonna be time for another replacement in a few months
By the way I tried Greenify today. The drain was far worse than when I didn't have it installed lol. Android Marshmallow is finally that one guy who's capable of handling himself alone without helpers like Greenify so try without it, it eats up your CPU anyway (as minimal as it can be, it still does).
With 3G always enabled I can get between 3 and 4 hours of screen on time (no games ofcourse) and around, idk, 10 hours total time until it hits below 10% and asks for some juice.
This^ was simply impossible with android 4.4.2 on the same phone so 6.0.1 really impressed me a lot as I had awful memories of Lollipop (that's why I didn't update for so long actually).
To sum up: try all the software ways of extending your battery life - with/without Greenify, uninstall/disable/optimise certain apps like Facebook and Spotify (says they slow down my phone), change ROMs, change kernels, change settings and if nothing works get a new battery.
PS: When Samsung go back on track and put a removable battery + all old features in a new flagship, I'm switching to that (S9, S10, SX, whatever xd). Newer phones got water cooling (~30 degrees while gaming, S5 gets 36-40C).

Thank you very much for your long answer. Honestly I don't trust too much battery savers. I've tried in the past many of them with no visible results. In fact greenify has never shown me any benefit. Notwithstanding, in this specific case, I've seen that hibernating "mi fit" (from xiaomi) I can appreciate a considerable improvement (5-10% of gain). I own a mi band and apart from keeping Bluetooth on (which seems not to be a big drainer) mi fit abuses of this connection. In fact "tools & mi band" seems to be more energy efficient with the connection to the mi band.
In any case I'll order a new one as it is not normal to have the drain for 100 to 90 being off and idle

I've changed old battery for a new one and I haven't seen any considerable improvement. After it, I've done a factory reset and a battery calibration (using the app on the store that requires root) and nothing... Any suggestion? I have the feeling that new battery is OK but somehow my phone is unable to take advantage of its performance...

Ive just unplugged it 50 minutes ago and I have 10 percent left with only 10 minutes screen off... There is something wrong and I don't think the two batteries (old and new) are in bad state in the same way... There may be something else..

Have you tried to install the stock firmware through odin? PS: Read the instruction before trying it!!!

Make nandroid backup with TWRP and flash official firmware. That's just not normal for any kind of battery (good or bad)

Right now I have DreamUX V2 A7 (2017). I flashed one week ago hoping to remove this strange battery behavior. But it remains. Do you think reflashing stock firmware will fix it? I'll check instructions before going ahead. Thanks to both!

If it gets fixed after firmware reinstall then it's a software bug. If it gets fixed after changing the battery then it's a hardware bug. If it doesn't get fixed after trying both things then it's black magic :s
Also try to clear dalvik-cache and cache and do factory reset before and after flashing.

OK I'll go ahead with this. Good guide to reflash stock rom?
I'll do several factory resets to see if it helps, but I start to think that it's black magic
Thanks

Sorry for the delay in replaying but I've made several attempts with not specially good results.
Now I'm getting 24 hours battery with 2h SOC for WhatsApp and browsing. Furthermore, I use Bluetooth for the miband.
The battery drop from 100 to 90 still remains. Maybe it's smoother but significant.
I've changed battery, changed roms (several times wiping everything). I've tried battery calibration app from rooted devices. I've tried the calibration procedure for non root devices (here I think I've obtained a little bit of improvement) but in general I have the feeling my phone is not detecting well the capacity of the battery (either new or old). Any tip? Advice?. Could it be the charging circuit? Can it be fixed? Should I keep doing calibrations more often to see if I grasp more capacity little by little?
Thanks for your time and help
