help with battery power

Hello to you all,
My new XDA Exec has developed a fault. It works OK when plugged in to the USB on my laptop or charger but when running on battery will only do so for a short time. In fact a matter of a few minutes.
The battery indicator shows the battery at 100% when charged but the phone turns off variously at 95 - 98%. I tried a soft reset and not change.
I tried discharging the battery using small lamp then recharging in the phone. The battery indicator did show a lower %age 80 ish but not as low as I would have thought. Subsequent charging made no difference and the problem persists. Has anyone seen this before? Any bright suggestions?
Many thanks to you all for you time.
Cheers
Piran

You battery is dead therefore you would need to change. You are not unique with this problem. That is common issue for Universal (exec) batteries. For your new battery: dont charge with the USB cable and charge when is completely drained.

Hi Bulldog,
thanks for the reply and the info. Regarding charging the unit from the USB port. Does the unit not begin charging as soon as it's plugged in to a USB port? Is there a way to prevent this that you know of? My phone was normally charged for about half it's life from the charger, half from USB.
From what I understand the LI ion batteries don't have a charge memory due to milisecond pulse charging so pardon me for asking but what does the total discharge do for the battery? Obviously it does something but what? (Not doubting you but I'm curious). Is there a away to ressurect a defective battery such as the one I have currently or is it a lost cause. I know some batteries can improve with either heating or cooling by about 20 - 40°C from normal operating temeprature, have you any experience with this?
Do you know if some makes of batteries are better than others?
Please pardon the inquisition but as I spend a lot of time in remote areas it's often quite handy to be able to bodge rig stuff in order to effect a temporary fix and it seems any bits of knowledge help!
Once again many thanks

Hi, I have the exact same problem...works fine when usb or mains connected but only for a few minutes when on the battery. Usually when I give it some heavy task stuff it will suddenly just blank out the acreen and die.
I'm going to try and do what's suggested on the wiki page about masking off the charge indicator contact with tape - run the thing down and charge up again.
otherwise it's a new battery - not expensive - and plenty about on ebay.

Hi Piran,
Be Frank I am not battery specialist. Therefore I cant give a deep explanation what makes the Universal Battery having so many problems with USB charging. For my understanding it is the slow charge which leads to Battery overheat. Therefore All the post here regarding the Battery problems suggest not keeping the universal charged with USB. Just search for Post for "battery problems" and you will find few "explanations"
In Regards whether you could reverse your battery issue. From my previous experience I would say the max the you can get back is some 10-15%. However in your case the issue seams more severe as you device turns off by 90-100% therefore I think you would need to order new Battery.
following procedure I follow to drain my battery:
1) Turn off You Phone Radio (important)
2) disable the "Turn off Backlight" and put your device brightness to "full"
3) let your device drain the battery by him self( prevent doing anything with your device during this time. I found starting application, touching screen etc. leads that the device request a pick of power which the battery is not able to provide and turns the device off.
4) after certain time your battery will be to weak to keep the device on.
5) push the "power button + backlight button + reset pin" to put your device in to bootloader mode. (your screen will be almost off just some info like SERIAL or Bootloader Version will be visible)
6) again keep the device in this mode to drain as much you can until you cant see anything on the screen.
7) repeat this point6 few times as sometimes the device turns of but after trying again the button combination you can put it back to bootloader.
With above the aim is to drain the battery much as possible. After that you charge your device with power connection for min.12 hours. I guess you will gain few % however repeat the draining and charging procedure for next couple charging cycle to see how much max you will get back.
Good Luck.

I faced the same problem with my battery on Universal.
After a complete drain, the battery wont recharge:
1) Connecting the power cord it starts the boot process, after few seconds the power led ligths in red once, the screen blanks and the boot restarts again and again.
2) Using the usb cord the power led flashes in red without further actions.
I have to throw away the battery, I guess.
Thanks for any comment.

Cesare, One thing you could try before given up on your battery. Try to Use your power connection to charge for while before starting up your device.

How much is a new battery?

Bulldog, many thanks for your replay.
When I connect the power cord the start up begins automatically.
There is a way to avoid the starting up?

Cesare, you right when you plug in the device it will boot up. However after while (ca.10-15) when the first initialization complete you could go and switch off the screen(with power button) which takes allot power. Anyhow in your case it is really strange as your device behaves like it has no battery at all. there could be 2 things leading to that.
1) your battery is completely dead ( check with a voltmeter to confirm)
2) or something wrong with your Connection clips (battery and device) you could again check with a voltmeter whether you get any juice on those clips.

Hi Bulldog.
I think that the 1st one is the rigth hypothesis. I'll check with a voltmeter.
The connection clips are ok because the backup battery works perfectly.
To drain that battery I connected an optical usb mouse until the mouse ligth went off. Do you think that this action is the reason of the death?
Many thanks again

Cesare, your battery my not complete dead but it is to weak to lighten up your Universal. Said that leads to bad thing which is: you can only start to charge battery when the universal has come out of bootloader mode.
I had such case ones, after not using my device for very long time the battery was completely drained, And as you described the device keep booting after plugging to the power. However after certain time ( I think some 15-30min trying) suddenly I was able to start up. I am not sure whether that would help to overcome the booting mode with less power but you could try to take out your sim card and memory card and try booting. ( again not sure it will help)

Guys - a quick update from my previous post.
I was suffering a sudden power outage at about 75%-85% battery power - just a blank screen - power gone. Didn't happen when mains connected, only on battery.
Well, first things first, I thought...dodgy ROM for WM 6 - so I tried a few of them - Ivans, Ranju's and Beastys - no change - still this power out.
Read the posts on this forum and thought - gotta be the battery's fried.
Sooo,
I ordered a new Genuine JasJar battery and installed it - (let it charge for 8 hours) - since then...no problems - no crashes, stalls or blank outs.
I'm running Ranju's 7.4 with spb pocket plus - htc home, etc,
As a point of interest my old battery stated 3.9Volts when I put my meter across it BUT - a voltmeter isn't drawing as much as the universal - when 'under load' from power intensive apps - hence you think you've got a battery putting out the requisite power when you haven't.
This was a real niggly problem to sort out with potential culprits all over the place:
Bad battery?
Bad ROM?
PCB crack?
Hardware Fault?
At the end of the day it's good to have spent £32 or so and simply got rid of the problem totally.
I'd say to anyone who's getting outs or blank outs at 80% power or below - your battery stuffed and no amount of mucking about with ROM swaps, Freezers, charging/ discharging is going to stop it blanking out on you.
I'd also like to say how appreciative I am of this forum with a great deal of knowledge available from so many users across a very broad spectrum of skills and experience. Nice one!
Hope this helps,

Charging stuck at 70%,PLS HELP

Guys pls help..I have this problem,that when I'm charging my trinity,it couldn't reach 100% of charging (full charge) instead was stuck to 70%.eventhough i charge it overnight.I'm thinking if it is a battery prob or the charger. i am using the originally supplied charger & battery.
Thanks in advance...

Have you tried powering the unit off, removing the battery for, say, 15 seconds, then refitting it and rebooting?... Check the battery level after reboot?... Then retry charging again?...
Maybe a full discharge might help "reset" the above problem too?...
I'm not sure, but I think the Trinity battery management is quite dependant on so called "coulomb counting" and I reckon sometimes it goes a bit wrong.

i tried all your suggestion bro,after rebooting,the battery meter increased 10%,tried to recharge,but still can't reach full.i tried to turn off my device then charge it,this time it goes upto 90%.it's a good sign but,charging while my phone is turned on is better right?i have no computer around,maybe i'll try to charge thru USB later..if it went ok,maybe i'll buy a new charger..thanx loopyloo for that sound advice..

Try battery callibration procedure!

The actual standalone charger (if that's what you're referring to) has no intelligence in it to speak of. Battery charge monitoring/status will be an integral function to the phone itself using dedicated h/w.
Something's not quite right with your kit somehow. Maybe the battery has gone a bit wrong (could be replaced - how much use has it had?)... Rather that than the phone itself, in which case it'll need repair.
You can try tnyynt's suggestion of Battery Calibration. Basically this requires you to totally discharge the battery (I suggest thru normal use of your phone!) then when it shuts down "cos battery is flat" reboot the phone into its bootloader screen (power down, then press and hold Power & Camera buttons until Tri-colour screen is displayed)... Then just leave the phone until it powers off of its own accord.
This may take a few hours (I did mine recently and it took @4hrs!) but the battery should be as discharged as its possible to get by that point...
And if you're lucky, it might just sort your problem out when you next recharge!
Good luck dude!!!

thanx again LoopyLoo,you made this procedure (battery callibration) clear to me,on how to do it.will try this procedure and will report asap the result.hope it works (fingers crossed),and hope it's not an internal phone prob.
Thanx Bro!!:>

Let me know how you get on.
I'm a little baffled as to why you have problems with your friends charge too but not USB???...

battery callibration not worked...
I'm sorry to report that after 3 times of trying the battery callibration method,my trinity still doesn't reach its 100% capacity of charging thru the standalone charger..but mysteriously charge a 100% with USB charging..I'm still not really sure why this happened..maybe will try to see a mobile technician for PPC..anyways,thanx for all your suggestion..will report ASAP after going to a service center..

Phone doesn't turn on

Hi all,
I'm having a bizarre problem with my OPT. The thread title doesn't really adequately explain the issue. Basically, if I shut the phone down, it will not turn back on. It won't boot to fastboot, recovery, or system. There is simply no response. If I plug the phone in, then after hours (or minutes, randomly), the battery icon will pop up with a red charging light (indicating a low battery?). However, it does this even if I shut it down with a full charge.
As an example, I shut it down before i went to bed last night (with ~80% charge), and left it plugged in. I got up this morning to no sign of life, not even a charging light. I unplugged it, plugged it into my PC, and an hour later I hear the little "new device" sound, and suddenly the red charge light is on. I wait some time, then attempt to turn on the phone. Then I hear the "device disconnected" sound, and it's dead as a brick again.
It also does this once the battery gets full. Eventually after attempting to power on the phone over and over again, it will randomly decide to turn back on, and then the phone works fine until shut down/rebooted.
Has anyone experienced this or have any advice? I'm hoping I just have something corrupted in my boot files or something software/firmware-related, but it makes the phone essentially unusable (and I certainly can't install a different ROM or anything while it's behaving like this).

Hi
Flashed Bad file ? Power problem ? Dead battery ? Charger problem and / or cable ?
But I already had that on my OnePlus 1 and I just changed the battery ... If it helps . Good luck anyway !
Be tested no choice. Unless you have the guarantee and a lot of time to waste in OnePlus...

I haven't flashed anything recently. I got the phone in September... unlocked, rooted, flashed TWRP, but haven't done anything since.
It's acting like the battery is completely dead, and it needs some time to charge before it will allow me to turn it on. But the battery is almost full.

You often dumps your O+ thoroughly ?
Because if so, it's not a laptop battery after I could be wrong but from my misadventure with OnePlus 1, it tires more battery than anything else. (On phone) :silly:
That way I'm not saying Fakir but I think if you have the guarantee, you should try to open a ticket to return your Oneplus. :good:
When my OnePlus fully discharged for a while he puts around 10 minutes to re-ignite (Oneplus 1) it is also how I ****ed my first battery on the OnePlus 1. :crying:
Not try to completely unload the O+2 from...
I'm just trying to help. :angel:
( PS : I still want to clarify that OnePlus 1 when it makes a point that the battery is empty it puts at least 10 minutes to light if I have the logo of the empty battery in red, even super you tell you my phone is dead ! And It is not ! If you know how is the process of loading a battery. And if such is your discharge too fast or you have a problem or charging your battery discharges of a sudden, I tell you it's more than problable so that your battery is lame. ) ( Sorry 4 my bad english.... )

The battery wasn't dead, I just shut the phone down. I very rarely discharge it all the way. Battery life is fine when the phone works. It's almost like the charging circuit THINKS the battery is dead and won't let it turn on. I'm not sure if this is a hardware or software issue.
Actually I just turned the phone back on. I just kept pressing and holding power until it finally responded and turned on. But now I'm afraid to reboot it again, or i'll be without a phone for 6+ hours.

Did you try to do a full wipe and install stock OxygenOS 2.1.2 ? ( Without SU or XPOSED ?)

Lenovo K4 note Charging Problem

Hi,
recently I am experiencing this deadly problem .
my battery drains completely to the amount that phone can't even boot . biggest problem is that its like phone is not accepting charge . after it loses all the charge,it turns off . when I connect charger it vibrates randomly . it feels like battery doesn't even have the charge to load that Lenovo battery charging animation page(while switched off ). phone goes to soft brick stage .after a few vibrations(I think phone is vibrating one time before loading battery charging page ,phone can't even load that charging page ,may be due to very low charge .so it vibrates and attempts to load battery charging page,and it goes off . again vibrates... somehow it recovers from the loop after some time )it loads battery charging page , and would stuck at 2%,or 8% etc... after long some 6-8 hours phone regains control and charge normally and everything coming to normal .I can't figure out what this problem is . only thing I figured out is that this happens when phone reaches a certain low battery percentage like below 20% .
after that phone will not accept charge until it goes off and all the above things ...
pls someone look into this matter ,may be someone else might have experienced this or someone can give me a clue

This problem has been faced by many users, including me. I thought it was only me, until one of my friends faced it too. Apparently, there might be a problem with battery stats. If you charge when it is fully drained, It will vibrate a few times. This happens because, the phone always keeps 2% of battery for the offline charging screen to load(the charging screen while off). But when the phone's battery is fully drained to 0% then it will vibrate and stays like that before it can switch on. So to solve this, charge the phone and leave it like that until its fully charged or like when you feel it is stuck(while the phone is switched off only). Then switch it on, and fully drain it again. Now once again charge the phone and leave it. Then drain. Do not remove until the phone until it shows 100%. Repeat this few times. This is actually to calibrate the battery stats. Now you'll see that battery charges properly.

No. It's not rom related issue. Each rom has some unique capability. Any rom is good. You can use Kernel Auditor to enable usb fast charge and charge the phone with any computer. This will work on any rom which has a kernel which supports usb fast charge

hii, guys i have problem too, unfortunately from yesterday, my phone doesn't charge but it is charging but not showing, it stucks to 42% and usb/Mtp is not recognized after plugin to pc.. i had shown all by pc side there is no problem in my pc but there is problem resides in my phone by the way i am on stock rom, pls help guyss to get rid out of this. I have done everything restart, reset but things aren't my side, i think this is hardware problem. i

Essential Phone keeps powering off

Hello everyone my brother's Ph-1 keeps shutting down right after powering up, I have tried everything from factory resetting to trying a different charger, nothing seems to work. This happened after he didn't use the phone for almost a month, it worked perfectly before.
It powers off even when on charge or connected to the laptop.
The phone doesn't stay on for more than a minute or two which means i cannot use ADB to side load an update
The phone is running Android P and the April security update patch.
Please do help me out
Thanking you

It could be corrupted though it sounds a bit like a battery issue, to me. If battery discharges too much eg it didn't shut down itself properly when battery was at a low level (they retain more charge than shown to user so it can shut down with proper procedure) & the battery ran down past it's reserve the battery may not be able to be recharged with a normal charger even though you charge it. (Thought a battery specialist could possibly revive it with a boost charge, though I've only seen these used with industrial batteries)
with a "dead battery bootloop" sometimes you can get it going by booting when connected to the charger, but you'll probably need a new battery. Maybe also try boot into safe or recovery mode when connected to Essential charger. (I'm assuming your phone not corrupted, though as you haven't given us much info about exactly what happens & what you are seeing)

The phone shuts down even when in recovery or safe mode whilst connected to the charger.
It does sometimes fully boot up and then shutdowns, but mostly shuts down while still on the essential logo.
If I may ask what do you mean by the phone might be corrupt?
Can one month of non usage cause the battery to die out?

by corrupt I mean some data that is part of the boot process causes bootloop so it shuts down, but as your phone is shutting down at different points in boot cycle I think it's probably battery
Leaving the phone turned off unused for longish periods should not be a problem normally even with a few % left in battery. And even if left turned on it should shut itself down when battery low & be able to boot up again after a month due to the battery "reserve" capacity (but possibly a month was too long). And if it was not recharged straight away and/or rebooted multiple times the battery "reserve" could fall too low and not have enough power to start/shutdown properly (possibly causing data corruption ... though l don't know if there is some sort of fail-safe boot procedure ) Then there is a possibility there is a hardware fault with battery/phone that meant battery lost too much power.
There were some tricks ie "boost charge" you could do with removable batteries that were in "deep sleep" as shown here for example

But they don't really work without taking your battery out (for us we might as well get a new battery when opening phone up, & there would be some risk that you damage battery as we do not know the exact charge to apply on this battery, which could cause unsafe battery) I wouldn't want to freeze my phone even though it should survive OK, as I'd be alittle concerned about long term effect on our screens small pixels (I remember the guys at popular mechanics put an old flip phone with little LCD screen in liquid nitrogen & it still worked after being warmed up!).

for more tech details

firmware issues do not cause the issue you are describing
you have a hardware problem
sounds like a bad battery to me
good news is the battery is not difficult to replace (don't listen to ifixit I am not sure what they where smoking when they did there tear down)

don't bother with silly and wrong tricks like trying to hack the battery back to life its the wrong way todo
if the battery ever gets to that point then the battery is bad enough said

So true! )) As much as I respect the guys from iFixit, they screwed this one up pretty badly - basically, made a tutorial on how to destroy your phone. Fixez.com did much better.
