[Q] MT4G Battery problems - myTouch 4G Q&A, Help & Troubleshooting

Hi all,
I have a MT4G running cm10.1. Prior to this, I was running toasted marshmallow's latest build.
Over the last week or so, I've been having some real problems with the phone. While in my pocket, it will discharge rapidly and switch itself off within a couple of hours of being off the charger. Other times, it will read a high battery percentage (80-90%) but will switch itself off randomly. When I go to switch it back on, the battery percentage reads 1%, and it switches off again soon after. If I try to switch it on again, it doesn't make it through the load process before switching off. It seems like the battery is completely discharged.
But (and here's the weird part): if I stick it on the charger, give it a few minutes, then switch it back on, the battery percentage will read 58% (both times I've checked this, it was 58%), and will then charge from there. It stayed on for the rest of the day when I took it off the charger (at 65% charge).
Edit: I though this might be a battery contact/connection problem, but shaking the phone / playing with the battery cover doesn't seem to bring it on. To be safe, I used a pencil eraser on the contacts and have a small piece of card in between the battery cover and the battery, to give more support to the battery. No reboots so far, but it's only been an hour or so.
So:
- is my battery dead, and can this be fixed by a replacement?
- is battery calibration needed (I know this is a controversial question; the consensus seems to be it does nothing)
- Is this more likely a hardware problem with the phone? I have noticed that the charger microusb cable does seem a looser fit compared with before, but since the battery was still charging I figured it wasn't a problem
Thanks for any help troubleshooting this!

Sounds like your battery is done...replacements are cheap...

What he^^ said.
Anker batteries are good and very inexpensive. Also, "calibration" does nothing. Just flash ROMs on a full charge and call it good.

Try to constantly check your what things are draining your battery, sometimes it could be the phone's data or it could be the sleep(idle) state of the phone, it could be many things. I tend to be always aware, check and read all the possible outcomes for the battery drain. For me is usually maintaining the data on my phone turn ON.

I have been having the same issue with my 10.1 ROM. It's not that old of a battery either so I don't think that it is dead; is there any other advice other than purchasing a new battery?

Switch ROMs and compare battery life? Also, check out Better Battery Stats. It can help you track down what causes drain.

This is the third ROM (starting from an ICS ROM) and the battery life is the same so I know it's not the ROM. Thanks for the app recommendation. I am afraid that I might have a defective battery.

As it turns out my battery has now started to leak and swell. I am going to purchase a new Anker battery. Thanks for all the assistance.

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 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

battery, battery and less battery.

Uptime: 2hours 27minutes and x amount of seconds and dead.
did I break the record for stress testing it?
Anyways, anyone got any tips on battery life? I was thinking of getting 3000mah or 3500mah, but the design of it (bulky) just doesn't seem the right option in my mind.
Also anyone here actually have the 3000mah or 3500mah so they can chime in on the design + battery life compared to the original?
just powered the phone back up. and it says battery is at 50%. wtf.
It turned off on its own cause of low battery, and now it says 50%?
E-gad the ghost recharge strikes again.
I had the same thing happen this morning. Woke up to a dead phone, plugged in, boot ed and battery showed around 70%... Go figure

Battery may not be calibrated correctly. I have to say my only major disappointment with the EVO is how the battery life is so tied to the particular rom I'm using. I mean I expect different drain rates on different roms, but having to recalibrate the battery every time I switch roms is just plain dumb.

It used to work for me, but now it is doing the same thing. Im at 1.76 now but for the past week it was stuck on 1.00, then slowly went up with each flash.
just a quick update. The reason the battery showed empty one minute and then it showed 50% the next was because of the heat. The phone was very hot when I was playing with it, and then when it cooled down it seemed to have fixed itself or w/e. Happened again today.
im sure its been answered..but how do we calibrate the battery?
Pretty sure you can erase the battery stats through clockwork recovery. Also there is a way through ADB which is pretty easy too
Sorry I don't have any links atm.

from what i can tell, battery life is MOSTLY tied to the kernal. Try an undervolted one, i've found they all work pretty well (hydra and KK)
o alright im using kings #2 BFS kernel undervolted and underclocked
I research before I got my DINC so I never used the factory battery from day 1. I have the same size battery but is 1750 power rating... I think Verizon has a newer one which was before I got mine...

Not directly related to the ROM. Check out the Hydra kernels. Also, with regards to battery, you need to do some recalibration so it works better. I got the 1750 battery for the DINC and it was dropping battery very fast no matter which ROM/Kernel combination I used. Finally found a thread that discuss how to get the OS to read the battery levels better. As an example, my battery would run down from 100% to 90% within 10-15 mins! After trying the following, everything works better.
Here's the thread: http://forum.xda-developers.com/showthread.php?t=714471&highlight=battery
Here's a summary of what you need to do:
01. Power off phone and change battery to full level (Green light).
02. Unplug the power and plug it back in. It should take another 15-20 mins to go green again (there's a thread discussing this also -- "bump" charge).
03. Turn on phone and go into recovery mode. Remove the battery stats.
04. Reboot phone and use without recharging until the battery drains completed - i.e. phones shuts off. May want to turn it on once it shuts off.
05. Charge normal and you should see a positive change in the battery life.
Hope that helps.
Yeah but how much do you really gain by doing all that? And how often if at all do you have to do it again. I have the 1750 and it seems to depend allot of what kind of signal and which radios are on.

Of course if you had bad or no signal, the phone will use up more battery. Normally when you don't have any signal and you check the battery status, the phone tells you to put it in Airplane mode to conserve battery.
For me, it's worth doing because my battery does not drain as fast for my usage. Since I did this over the past 2 days, I've had the phone one on a single charge with about 6 hours of Awake Time (gaming, Internet, phone calls, texting, emails, some GPS usage) and UP time is 22 hours. And the battery is down to 20%. Definitely an improvement for myself so just try it if you like and see how it works out. Everyone's usage is different so it's hard to quantify.

bump charging before wiping stats makes no difference. bump charge is still necessary regardless. until htc acknowledges its a problem and fixes it on their end, bump charging is a part of our lives if you want a fully charged battery. unless you use an external charger of course.
I charge externally and I still bump charge tho I don't need to power the phone on and off. Also the bump time is much shorter

Nah, Virtuous gets really good battery life, especially with the custom kernel built for it.
Does JuiceDefender even function on CDMA phones? I thought it wasn't working
I would also like to know this! What about SetCPU profiles too? I just want the best possible battery life, speed is not very important to me.
So, who has tried out various ROM and Kernel combinations? What have you concluded gets the bets battery life? Thanks!
im in the proccess of downloading and setting up virtous ill report back with different kernel set ups. i just want a rom and kernel set up that will last easily the hole day
Bump charge with or without battery stats wipe doesn't seem to make much difference for me. I plug in at home/car/computer and carry a spare battery. Just wish there was a way to turn off 3g and force 2g with Verizon on CDMA phones. That way I could still have data/internet.

Battery performance after ROM Upgrade

I just flashed SyNthetic_aospX 1.0.0-BR7 on my HTC Glacier and started observing a little weird behavior with it. It died of battery, but when I restarted it, the phone showed 10% battery remaining.
I switched off and put it on charging, after 1.5 Hr, the charging indicator was still yellow but I switched on the phone and boom, it showed 100% charging and the led turned green. To double check I switched off the phone and plugged in, it was still showing yellow led. After around 45 mins, the battery was fully charged in off mode.
Is this some behavior known to anyone? Or it is time for my battery (my phone is still with original battery and it's almost 2 years).
Any help is highly appreciated ...
Well, first off, did you flash at 100% battery?
Second, is your battery swollen at all? It probably is after 2 years. I had to replace mine after a little over a year.
I can tell you that, even on CM7, I leave my charger off while in recovery because it might say 50%, but as soon as I reboot it might say 70%. A magical 20% increase in 45 seconds. Still, your battery behavior is off. If you decide to replace it, check out Anker.
Don't forget to flash another ROM to compare battery behavior.

Thanks estallings15, I initially flashed at < 100% but then realized my mistake so did a full wipe and then charged it to 100% (when powered off). And then flashed it again.
Seems my battery is little swollen, can't say though, I would give it a shot to replace it.
I tried another ROM but did not use it for full battery cycle, as I just love this ICS
If you decide to replace it, check out Anker.

[Q] Miscalibrated battery, need help!

I need some suggestions on how to calibrate the battery on my n4. It got miscalibrated when I did the update 4.2 to 4.3 and I haven't been able to calibrate it since then, a week ago.
I tried using battery calibration from the store but it didn't work, I tried charging the phone from 0 to 100 and it didn't work.
I remember I had the same problem 2 years ago with my Atrix and I solved it by wiping the battery stats from recovery, but now twrp and Cwm removed this feature and I don't know how to solve my problem.
Maybe it would help flashing all back to stock with the toolkit?
If you have any suggestions I'd really appreciate it.

Just the answer I didn't expected, and frankly a pretty useless answer, everybody knows that battery calibration doesn't improve battery life.
But I have other problems, like I turn off my device at 80% and when I turn it on it's at 77%. Do you think that's normal?

2.Charge fully(+2 hours after hitting 100&) WITHOUT disconnecting from the charger.
3.Repeat for better results.

To be honest, I don't know.
But if I would be you I would just let it charge while it's off(So the big ass white battery icon).
Let me know if you got your battery sorted after the method I posted!

Just the answer I didn't expected, and frankly a pretty useless answer, everybody knows that battery calibration doesn't improve battery life.
But I have other problems, like I turn off my device at 80% and when I turn it on it's at 77%. Do you think that's normal?

You mean off as in all the way off? If so, then that ~3% is being used when the phone boots.

I've had many phones, and none of them lost charge during the boot, at least not that many. I think that's the clear sign of battery miscalibration, I've had this problem before with another phone. Besides that, I've had a strange behaviour of the battery, for example I saw it lose 4% in 1 second, from 66 to 62 in a blink of an eye.

It's not that it's losing charge quickly, it's just the OS (or the hardware itself) doesn't always do the best job of reading it. There's not much you can do about that, and it's really not an issue unless you make it so by staring at your battery level all day.

Hi,
I'm having a similar issue. Phone rebooting to weird battery levels (not the %age it shutdown at).
Phone shutting down at 31% battery and rebooting to 0%.
I tried charging only to 100% yesterday with the phone ON.
Do I have to charge it even after it's charged to 100%?

I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
Also my nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171 (in batter monitor widget)
Please tell me what I should do.

Before you replace the battery try to disconnect the battery's flex cable and reconnect it [after you charge to device to 100% and turn it off of course] check if its 'reset' the battery.
