[Q][SOLVED] Device turns off at 45% Battery

[Doctor Luk]

Hello enthusiasts,

I'm having a problem with my HTC One Mini (from German Telekom).
The device keeps turning off at around 45% battery charge. There is no warning prior to the shutdown. You can briefly see the "Battery is low!" warning for a tenth of a second until the phone shuts down completely. It can then not be turned on again unless I plug it into the charger. When turned on immediately afterwards, while charging, the battery status has changed to 0%.

There is a screenshot attached which shows the Voltage of the battery about 2 minutes before the device shut down.

I have already used the search and found numerous threads about devices shutting down with a high battery load, but the linked tutorials are often obsolete or unappliable.
I've been studying Wikipedia articles about Lithium-Ion batteries which say that the lowest voltage for a battery generally is 2.5V. Many manufacturers implemented security measurements that keep the battery far away from this low voltage level. I expect the 0%-load to be around 3V, but 3.3V should still be rather "loaded".
Concerning the overall device duration after a full charge: It has become far worse. After first flashing Cyanogenmod M11 Snapshot M6 a fully charged battery would give me around 20h of time until it would die. I've always recharged the device when it reached about 20% charge, before it turned red. Now it barely manages to get to 12-14h. And I don't even use it heavily.

I've already tried some battery calibration apps, but they all haven't shown any influence on the symptoms.

Information about the system:
HTC One Mini
Cyanogenmod 11, Snapshot M11 released on 2014-10-08 02:18:05
Battery Apps: Battery Doctor, Greenify (no difference with or without these apps)

I'd be glad to provide more information on this matter if I forgot something, but I hope I got everything you need. Would greatly appreciate help as this problem is slowly grinding my gears.

Have you tried using a different ROM?

Have you tried using a different ROM?

I've had the stock ROM installed for about 7 months until July and then I've only installed different versions of Cyanogenmod.
Namely Snapshot M7, a Nightly one from July, back to Snapshot M7 (at this point, the problem with the battery started occuring), then a nightly from October 6th and just recently the Snapshot M11. It should be noted that I've always wiped the system partition before installing a new build.

Flash a stock ROM and see if it still happens.

I have this problem also on any roms. But my isn't at 45%. It's usually at around 14% or 30 something. After it reboots my battery will be 0%

 

[Doctor Luk]

I've had the stock rom running for some time now and the battery display is absolutely fine with it. As soon as I go back to my CM M11 backup and recharge the phone, the measurement gets all confused and the phone starts shutting down at ~45%-50% again.

I have the same problem. As soon as my phone gets to about 40%, the battery drains to 0% within minutes, even while the screen is off and no data is being used. My phone is just over a year old and running a rooted, but stock version of 4.4.2. I don't think it's ROM related since it only started doing this recently. My guess is that our phone batteries are malfunctioning. Check out this person who has the exact same problem I have on the One M8:

http://forums.androidcentral.com/htc-one-m8/396770-htc-one-m8-battery-drain-40-60-0-seconds.html

His screen shots mirror mine EXACTLY. One thing I discovered is that while charging from 0% while in recovery, I was able to see my battery percentage jump from 7% to 50% when I booted to the OS. The battery then died again minutes later. This only happened once, but I'm guessing that our phone might be displaying a higher percentage than what is true just before it dies.

I have a strong feeling this might be CyanogenMod related, as it is known to have caused great problems on dozens M4's with overheating / strange battery drain / weird stuff like that, among many other bugs.

If I were you, I would do a fully clean install of a stable Sense-based ROM and kernel on upgraded firmware and see if problem persists.

1. Upgrade to the latest TWRP recovery
   
2. Wipe everything
   • Factory/Data reset
   • Advanced wipe: Cache / Dalvik Cache / System / Data / Internal Storage
   • Format Data
3. Upgrade your firmware, if not done yet
   
4. Install latest InsertCoin, choose "Perform a full wipe" option in AROMA
   • When installer finished, uncheck "Reboot phone now" and get back to recovery
5. Wipe [Cache] + [Dalvik Cache]
6. Install latest Xceed kernel (for Android 4.4.3)
7. Wipe [Cache] + [Dalvik Cache]
   
8. Reboot

I wish it was that simple. Thought CM may have some known issues, my device and the other example I linked to are running stock Roms.

If it wasn't happening every single day, it wouldn't be such a big deal, but now I'm seriously worried that I can't get a full days use from it anymore and it's barely over a year old. Sending it back to HTC would be a huge pain since I'm rooted. Though I guess it would be worth it in the long run to finally have a phone that doesn't shut down at 40%

Hello everyone, sorry for the delay.

It looks as if there might be damage to the battery as the %-display for the battery is still wrong on a Stock ROM (rooted and outdated) that I've had on the device for a week now.

Okay guys, what to do next? I guess I would like to completely revert everything and reset the phone to 100% stock. Would you guys recommend opening a new thread for that?

Anyway, here are some details:
Kernel 3.4.10-g8974365 [email protected] #1 SMP PREEMT
CID: T-MOB101
TAMPERED
UNLOCKED
M4_UL PVT SHIP S-ON RL
HBOOT-2.22.0000
RADIO-1.24.40e.00.26
OpenDSP-v19.2.0268.0927
OS-3.10.111.4
eMMC-boot 1024MB
Feb 14 2014, 17:48:26.0

I'm running a Stock branded ROM (T-Mobile Germany) with Sense 5.5 and Android 4.4.2 which is OUTDATED, however using the stock Recovery, I can NOT install OTA Updates as it stops at 50% showing the attached image (courtesy of droider.eu).

So the plan is to get the default Kernel (remove root), make the Stock ROM updateable, remove TAMPERED [might require S-OFF if I'm correct] and get everything LOCKED again (and not RE-LOCKED). I need your help to achieve all of this and it would be awesome if you could help me or just tell me to open a new thread.

I am in the same boat with you. I have completely given up on this battery. It's not ROM related. The battery simply doesn't hold a full charge anymore and the only remedy is to send it back to HTC for replacement. Since my phone has no insurance or warranty, I'd have to pay for it completely out of pocket. Fortunately, I've got my old HTC One S that still works perfectly and just loaded the latest KitKat Rom to it. The battery life and over-all performance of the One S is nearly better than my One Mini. I'm not feeling very compelled to get it fixed at the moment, but I'll let you guys know how much it costs if I change my mind. Good luck with yours.

 

[Doctor Luk]

Thanks, I'll just have to get mine fully back to stock to be able to turn it in... Hope it'll not be that pricy for you.

 

[PuffDaddy_d]

Can you get rid of the tampered warning on the boot screen? I thought it was irreversible. If not, I don't think HTC will warranty it.

Of course you can, at least I assume you can. On the HTC One there are already guides and I guess the Mini is not that much different. It requires S-OFF though, so at least I would have to tinker around with my phone even more.

Our Plain vanilla -stockROM One mini is having similar issues:
It shuts down at battery 30%
- removed unneccessary app's - no result
- Factory reset - No result

Contacted HTC support, they advised to run self-test ( *#*#3424#*#*) in safe mode
Tried that: Boot-up in safe mode - charge full - batterytest : Put it away for the night while batterytest running, hoping for a report in the morning. Unfortunately no report, but a battery status of 1% - so no shutdown at 30%

Second time: Charged full in regular mode (100%) - reboot in safe-mode: Battery shows up @57% and could be charged for at least one hour.
Ran battery-test : after one hour of testing, battery = 91 % while 71 % is lower limit for failing battery, so battery succeeded.

Third time: Just testing the difference between battery-status in regular mode vs. safe-mode
Full charge in regular = 50% in safe mode (and able to continue charging)

Don't want to sent it away for repair: expecting to have it sent back after a couple of weeks: " we did the batterytest, and it's functioning fine. Your device is not broken"

My idea: something interfering with the battery-status indicator ?
But what ?


Any ideas ?

not sure it works, but try this
the wiping the partition cache from stock recovery is not quite the same as factory reset

Thanks for reporting a similar problem to mine. I haven't gotten to fix mine, yet, too. Mine even powers down at 75% Battery and now has a horrible battery life of about 2h of normal usage (occasional screen activity, listening to music).

But how did you find a batterytest? I can't seem to find one in the safe-mode via that dial code. Can you explain where you found the battery test?

Wow - I wish you had posted this 2 days earlier! I just had a new battery purchased for my phone and I'm getting a local repair shop to replace it. Sounds like my battery could be fine and I will likely have the same results after it's replaced!

If you fully charge the phone in safe mode, does the phone battery still last the appropriate amount of time in regular mode or does it still shut off prematurely?

Dial *#*#3424#*#* and click <more> in the right lower corner

not sure it works, but try this
the wiping the partition cache from stock recovery is not quite the same as factory reset

Not sure if I understand this: I did the Power-button - volume down - 'Factory reset withour keeping data" - as given on the HTC website

It still does: Fully charged in safe-mode it shuts down @30% - does seem to last longer to reach 30% level

Last night I tried a different trick:

After shutdown @30% I kept the phone off and recharged it to 29 %
I put the phone back on and drained the battery to 0% - ignoring all warnings ("please charge .... CHARGE ..... G*DDAMN START CHARGING, I'M FREAKING DYING HERE ....)
Recharged the battery while powered off from 0% to 100%
Tested this morning: Same battery level in regular mode as in safe mode (98%)

 

[PuffDaddy_d]

Hmmm, I seem to remember doing some thing similar by accident with my phone when I stopped charging around 30% to use it. It drained to 0 shortly after and I fully recharged while in recovery mode. The battery seemed to last longer that time, but any subsequent charging before letting the battery die seemed to result in the same poor battery life. It's not a real solution but if you can confirm that yours acts similarly, then it's more info for us to have as we try to figure this out.
