I am facing a problem with my O2 XDAII mini since the lats 10 days. My device seems to abruptly shut down itself any time of the day on battery power. If I keep the device connected to the charger, then it does not shut down however on battery power, it shuts down even if the battery shows 100 %.
There is no fixed time interval for this and it happens abruptly anytime of the day.
Kindly let me know what could be the problem with my device ? Has the battery reached end of life. I have bought the device around 6 months only. :?

Hey guys,
i have a Vodafone VPx now and all has been great, however yesterday it reckoned the battery charged from 8% to 100% in 10 mins, i left it on the cradle over night, and now the device doesn't show any signs of life apart from a red charging indicator. I took the battery out and metered it, shows up at 3.72 Volts, so battery holds charge. What can i do to get the device to power again?

I'm not an expert but I would suggest to leave the device in the cradle and try to boot it when charging it. In this way you can decide whether it's a battery or some other malfunction. Maybe the internal backup battery needs to be replaced, but I don't know if it would let the battery indicator LED to blink...
I replaced my battery because it showed that it's fully charged but when uncradled the device won't connect to bluetooth devices or regularly drops the connection, it even resets itself although the indicator displaying full charge. Now everything is OK. You may consider buying a new battery if it's older than 2-3 years, but first test if that causes this behavior.
hi,
actually i'm experiencing the same thing..
my BA if used to connect to wifi, not more than 5 minutes it will hang with the screen goes blank.. so is it because of my internal back up battery that needs to be replaced or my main battery that need to be replaced?
FYI, backdays before, i got notification that my internal battery runs dry..
Ive just bought a BA off ebay and it came with 2 batts, but 1 of the batts keeps causing the BA to turn off evern if the batt is fully charged.. odd hey?
speedy2009, I think that one was the original battery bundled because it has no value any more so the seller sent it with the machine, all in all it's not a bad device for it's years.
jilaxzone, don't know how to test this, because sometimes the device gives false alarms, I would take it to a PDA shop and let them replace the internal battery as this is cheaper than the main battery.
Also Ive figgered out that if the backup battery is low, it gets charged up from the main battery.
Should everything be lost from the memory once the backup battery runs out? Cos I did try this morning, taking the main batt out and left the phone for about a hr. When I put the batt in, even tho windows said the backup batt was completely empty, it still had all my info in windows??
Hi, the backup battery is responsible for the time and date. The other functions of it are unknown to me. Fortunately the ROM storage is not lost when the battery drains completely

If thats the case theres no real reason for a backup batt cos it only takes a few secs to alter time and date, like on a normal mobile phone.
Hi
after a connection via activesync yesterday I realized the battery power jumped to 100% and remained. After CID Unlocking and trying some WM6 Roms here the problem is still there. The Device is running perfectly but there seems to be no obvious power draining as the battery display is stuck at 100%..
Funny thing is when I turn it off and charge it ,then after 2 or 3 secs the green LED appears?? I'm afraid it will discharge completely without being able to charge again.
Anyone experienced the same? I have no idea, driver problem seems unlikely to me as it won't charge in Off-Mode..
Thank you
Problem solved itself. Battery at 98% after 14 hours...

Hey guys,
Assuming you have read the title there is something weird about my phone.
It shuts down at 40-50% battery (before it shutsdown it says empty battery briefly and then the htc flash screen appears and shutsdown).
The weird thing is the following:
It shuts down at let's say 40% battery, but when it re boots the battery is litterly empty (even when i boot in recovery it says --%, and when i plug the charger it starts at 0% again).
I have tried:
Battery Calibrator
Empty full fill up with wall charger and also tried usb charger.
Screaming @ phone
wiping battery data in recovery (4ext recovery)
The thing i am most confused about is that it goes out at 40% and when i turn it on again it's 0%. This never happened as it happened for the first time 2 weeks ago, confused. I tried different roms and it still happens (even ICS roms).
I wouldn't really mind if my phone would shut down at say 20% when it says actually it's @ 20. But as i said before: It says it's 40 (batterij indicator htc sense half full) and then shutsdown realizing after reboot it's completely empty.
Any help is much appreciated!
Mendel
Shutting down on let's say 15-20% is quite normal, but I never heard of one shutting down at 40%
Are you using the stock battery, that came with your device?
Sent from my HTC Desire using XDA
Any chance to try another battery? Seems really strange cause in most cases if you wipe battery stats you get your phone shutdown at 20%, not 50%.
Its most likely a bad battery that needs to be replaced specially if tue same thing happens when using a different rom.
via xda app
Yeah i know it seems so weird that's why i started this thread.
Before i buy a new battery:
What could be the cause that the phone goes out at 40% (or 30) and when it reboots it's empty.
Seems like the phone or the battery aren't in "sync" until it reboots to show it's empty.
Any tips or suggestions?
Thanks!

I'd like to think of it similar to laptop batteries that have gone bad... you plug your laptop to it's power supply, it says fully charged but as soon as you pull it out from it's power supply it drops to 50% in minutes and then goes off. The battery cannot hold the charge anymore.
It can only mean that the battery's life is at an end. The only thing you can do is to change it. I suggest that you stick to original HTC battery as the "ChinaMade" ones will die a lot faster and you'll have to change it sooner than this one.
Regards.

Hey guys!
I know this thread is started since several months but I actually have the same problem : I have a HTC Desire and its shuts down at about 50% and when I reboot it, it says the battery is empty.
I tried several times to recalibrate the battery (and to do all the things MendelMusic said in his post actually) but nothing changed.
MendelMusic, did you finally manage to solve your problem?
Anybody have a solution or any ideas?
Thanks!

Mine used to shut off around 32%. This forum fixed this issue:

Battery drain?
It's called battery drain. I have it too, but only at 10/20%?
If someone knows a fix, please send it to me
AW: Htc Desire Shuts down at 40-50% battery
Probably your batteries are just weak now. I'd recommend you all to invest 5 bucks in a new battery. Actually that helped at my old desire. Greetings
Thanks for your answers!
I tried the link of madreef and it didn't change. I will try again, maybe I did it wrong (hope it will work this time...)
@dschibril : I don't think my battery is weak because the problem occured as soon as I changed the ROM (CM10). The battery was perfectly ok before that.

Hello, I have the same problem with you. Did you manage to fix it and how? Have you tried a brand new battery so far?
It has to do with the Desire's poor battery age management system. Li-Ion batteries age, meaning that, as time passes, they're gonna be able to hold less and less milliamps. After almost two years, my Desire's battery can only hold 82% of the original ~1400 mA charge.
The only way around this is to use the Nexus One Battery Calibrator (Nexus One and our Desire share the same hardware underneath the hood). You'll need a compatible kernel and some patience. Instructions in this post.
My 2 cents: if your battery is only able to hold less than say 75%-80% of its original charge, then you should replace it. Li-Ion batteries age in such a way that they suddenly go dead, so it's not worth taking the risk.
Later Edit - If your Desire shuts down at say 40% - 50%, that means that your battery is 40% or 50% gone, so it's time for a replacement. I'd still try the battery calibration method i wrote about in the above post, just to determine if it's a freak software error or the battery's fault.
P.S. - Wiping battery stats does nothing to solve most issues (for the Desire, at least).
My phone turns off sometimes at 50%, sometimes at 80% of battery.
I have new battery now (original one) and it is the same. Phone turns off, only when it is connected to charger it does not.
Hiii
My hTC Desire 728 shut down when then battery showing 50% to 60% in charge. What is the remedies?
Hi, after 3 happy years with my xperia s, here it is a major issue. Three weeks ago, in the middle of a phone call my xperia shuts down (battery at about 85%) and no mean to restart, it was like dead. No led if in charge or connected to my pc. After three days, a friend opened the phone, pull of the battery, reconnected the battery and, here it goes, it started again. But, another issue now, battery drains at 10% each hour in stand by. I changed the battery with a new one, same thing, i had a hard reset, same thing. Battery status shows 30% consumed by the screen (but it was only 15 min !) and google services 25%. Anybody has an ideea how to fix it ? Thanks for your answer.
Hello Guys like me many of you have same problem with battery life, since i updete to MM my Battery start to droping very fast and suddenly die sometimes at 20% sometimes at 30% sometimes at lower %.
Something doing this we have lost all settings and after we boot the device again have to set up everything from scratch.
At the begining i was thinking my battery is DEAD and need a replacemant but in the past few months when i read hundred of Threads regarding this issue i realize it is not possible often after MM Update or flashed a MM ported ROM from HTC 10 this to heppans to so many users on the same time.
Ive tryed almost everything from fully Discharge to cleaning Caches Art etc and re flashing few times clean a new ROM nothing helps at all even some software for calibration make the things worse.
In this thread i found a solution given my HTC themself : http://forum.xda-developers.com/htc-one-m8/help/phone-loses-settings-apps-battery-dies-t3375980
And i did try it several times without Luck
I did keep reading and found out that really Holding Volume UP + Volume Down and Power Button did clean the Battery Cache but i was doing it all the time wrong.
What i did try is this:
Turn off the Phone lets says you have 40 50 % battery left.
Wait for a minute or two, then Press and Hold Volume UP + Volume Down and Power button for at least 6 Restarts, release the buttons when your device swtich ON after this 6 restarts and see your Battery %, usually what gona heppand there will be diference in the reading. ( When doing this DO NOT PLUG YOUR DEVICE FOR REACHARGE)
in my case doing that before the operation i had about 46% after that i have 55% this is the 1st thing i spot on.
After i did this, start using my device with heavy use and i saw the battery behave normal and the droping its not so fast like before in order to chek do i have any more wrong readings i decide to prepare the test again.
Switched of the Phone at 40% after all the restars and turned it on i had 39%
so i think this was normal and the battery do not have anymore any wrong reading %.
Start to use hard the device watching videos listen music 1st think i notice is the % are droping really slow not like before.
At exactly 15% Battery left i recive a Warning like it should be!!! (i didn`t recive any warnings like this in the past few months) then i keep using it hard and waited the battery to drop even more to see whats gonna heppand.
Well at 5% all was perfectly fine NO restarting at all.
At 2% i put my device for reacharge and after the full recharge to 100% now seems the battery to HOLD really Good 24 hours latter with intensive use of the device the % are droping really slow like it should be.
Now its seems that all is fine.
Try this and report back.
Its important DO NOT PLUG THE DEVICE when you doing this! Its make SENSE even if from HTC says PLug it ON (DO NOT) because when you cleaning the Battery Caches you want it CLEAN not on the same time that power from the charger to reach your battery this can lead to wrong INFO again so its really make sense you have to do it without to Plug in order to see the real % you had.
Later on i will make some screen shoots to show you how the battery Hold after this procedure.
its seems now i lose 2% per 1 hour in standbay witch is PERFECT for old device.
I've also had this issue. Didn't know about the volume button trick. Well now its too late and the battery is totally shot I think and won't even turn on or charge. Don't know what to do about getting all.my unsaved data off the phone. Was wondering if it would be possible to temporarily hook up a battery from my old m7 just to get the data off my m8. Anyone have any input on this? Is it possible to just temporarily connect an m7 battery to an m8?
Good lord..
I have the same issues for over a year now, so I had to test it out.
Before the restarts my battery had 52%, now it has 13% (battery saving mode is enabled, something i havent seen for years...).
I hope this problem will be fixed now.
I will give an update after a couple of days to see if it actually worked.
I'm running lineage os 15.1 oreo with sense.
Thanks anyway!
I held it for 6 restarts but it didn't turn on automatically. I had to let go of the buttons. Battery dropped from 69% to 48%.
Held it for 6 or 8 restarts and dropped from 40% to 18%, hope it will make a change. Thanks for the guide!
Update to my previous post: Battery lasts a longer, but dies at 22% percent, guess its the problem in the battery and cant be fixed via software
Did you guys get successful preventing sudden phone-off?
I recently bought this device. It was already updated to marshmallow. I did the volume button thing, at first htc's way. Then I saw this way and tried that. In the very next boot,everything is okay, battery drain till last drop. But in subsequent boots, problem reappeared . I tried wiping cache partition with twrp. But the problem comes again. Did you guys get it solved 100% in one time? Did I miss something? Or is it like me everywhere ?
Why do it at 40-50%?
