If my HD has 20% power left and is running program, it will always power off without low power alert after a few minutes. Then, you must recharge it for power on.
In addition, I found that the refresh interval of power indicator looks slow, in other words, after it has been charged and run for a while, the power indictator is still 100%.
Can anybody tell me the reason and how to resolve it? Thanks!
Are you using the original battery?
Battery level is rather inaccurate, especially with 3rd party batteries, so don't take it for granted.
The battery is certainly an original battery.
Is there a possibility that the issue is relative to ROM version?
I have a experience that I flashed a rom of version 21109 into my HD, the issue occured every time. Afterward, I reflashed a stable rom of version 20769 back to it, the issue has never occured. But, several days ago, I flashed the newest radio into my HD, after that, the same issue occured anew.
I'd blame the battery, if it dies when your unit reports 20% charge, it must be in a pretty bad shape. If you can find a spare battery, give it a try...
was anything more found out about this? I also find my battery indicator very slow to update....soft reset my device and lost 5% power according to the battery...I have even had the reverse effect after a charge,....soft reset after a charge and seen MORE power than indicated.
This is making me paranoid and search for every last tweak to save power but it might be that the indicator is wrong in the first place - ideas?
Charge the battery full and let it drain to zero,and one time again.this should recalibrate the powermeter.
or your battery is old and broken...if you often charge your device when its not even required the battery will loose power and be dead in a very short time.
i know my english is not the best,hope you understand what i mean
I know there are already a lot of discussions on battery drain and believe me, I have read every single one of them. However, I think mine is slightly different:
When fully charged and using WIFI for 10 minutes, 10% of juice will be used. Listening to MP3 for 1 hour will also use another 10%. Overall, battery life is really bad but the key is it only happened suddenly. It have been very good up till now.
I have tested this on another battery and have exactly the same results so it is not battery related. I have also hard reset the phone and tested the battery with nothing installed and it still drains. A full charge only lasts me like 4 hour of very light use.
I installed Battlog and the power consumption is around 90 which I think is pretty low, but at times, even with this low consumption, I can see the battery usage literally falling before my eyes, like 5 % in 5 minutes.
I have also tried the HTC battery test, i.e. fully charged the battery, turned on plane mode and full brightness. After one hour, it only used 8% which I thought is normal. However, if I start using the phone by just simply clicking around, it will start dropping.
I believe the phone is fine on standby but once it starts doing things, even simple operations like moving around folders, it starts consuming a lot of power.
This all happens after an overnight charging episode when I noticed that the light stays amber in the morning and the percentage stays at 80%. I soft reset the phone and it immediately show 100%. This has never happen again but my battery usage is never normal since.
All in all, I think it is somehow hardware related, like the battery gauge is bad or the charging is never complete but it still shows green. It is still under warranty but I think will be very difficult to convince the service centre that there is something genuinely wrong with the phone.
P.S. Should also mentioned that I am using the stock telstra rom and have also cycled through the batteries twice before testing.
I had the same problem...
You should try resetting you battery:
1: let your battery drain to 0%
2: fully charge your battery while keeping your phone off!
this solved the problem for me..

I had actually "reset" the battery but only drain it to 5% before recharging as I have read that it is not safe to drain to 0%. I'll try to completely drain it tonight and recharge. Will report back.
btw, I noticed that when the battery is charged to 100%, the led stays amber for about 15-20 minutes before turning green. Is this normal or should it turn green immediately after reaching 100%?
Tried completely draining the battery and charge overnight but have no effect. The problem persists. So this is definitely not a battery problem.
I guess the last thing I can try is charging the battery with a standalone charger or another HD to see if there is problem with the charging mechanism in my phone.
The latest Telstra rom seems a bit better on battery
led amber
The led amber must turn to green
immediately after unplugging.
some thing is wrong with your charge
system .

aidinali, can you please explain what you mean? I thought the led will go off if you unplugged the charger. My problem is that after reaching 100% as indicated on the phone, the led stays amber for another 15 minutes before turning green.
Well , I'll correct & explain more....
1-when you reach %100 ,the led will turn to green immediately (if you’r phone is plugged in).
2-if you unplug ,the led will turn off (as you said ).
The problem is that since the battery meter in HD has not been defined by percentage , it doesn't match with
Apps like battery level or battlog .so when you see %100 on them , it' s not "real % 100 ".
I believe there is something wrong with the phone as the percentage usage and charging status do not match. However, since the basic HTC software does not have any battery usage in percentage, it’s hard to convince the service centre that something is wrong.
Any software that shows the battery as a percentage all have the same reading, so I assume they all rely on the mainboard for that information. There is obviously something wrong with either the charging process of the phone or draining more battery than it needs during usage.
I have 100% exactly the same problem as in the original post.
Does anyone else?
I have also tried 2 batteries and had exactly the same results with both, so I also know it is not the battery. The only app I have installed other than Dutty's 6.5 rom is Tomtom which does not need to be run for any of these issues to occur.
Any chance on warranty? I think it's software...
Try a different ROM. I've been having the same problem. I just flashed a new ROM about an hour ago (partly because Dutty's 6.5 kept freezing). I'm hoping both problems will be solved now.
i've found the latest radio rom to make a big different to battery life. 1.14.25.24_radio
the previous radio rom (1.13?) did suck the juice and made battery last 2 days less than 1.14
Try charging with a different charger. Ie. connect a USB cable on your PC and charge it from there.
I've had very similar problems with the stock charger a month after i got my TouchHD, and ended up testing with my old P4350 charger and all problems went away.
I've had similar drains even witch WiFi off, no emails, exchange or 3G access...
Now i'm getting a whole day's usage and i'm left with 30-40% battery, with 2 hours average talk time
I've tried with a number of chargers.....battery still sucks.
I've just switched from Dutty's to Energy ROM, radio is 1.14
If anything...energy drains more quickly than Dutty's
It says it drawing 350mA
Ok, I've used Energy ROM but now using Dutty's Leo. The only thing I've loaded so far is Battery Guard which say it's drawing 98mA when on standby(ie....backlight goes off). That'sa massive difference on the 250mA readings I used to get....now all I have todo is figure out which program I'm loading that is killing my battery.
That still only equates to 12 - 13 hours on a good standard battery with no use at all.

Standard battery should last longer. Sounds like your battery may be slightly faulty. Make sure you let battery drain fully before charging, and always try charging with device off. Should help improve strength.
I had same problem when i flashed miri's rom, hd got warm and didn't last, it cooled down in standby, the answer to my problem was that the wifi was not set to save battery mode, once i set it to save power everything was ok
Used 8% in 24 hours

Have been trying that for a month now....something seems to have suddenly worked It only used 8% of the battery in 24 hours! I live in the rainforest with no service so cellular was turned off...wifi on, but I only accessed it about 6 times......still,nothing has changed. The same conditions would leave me with a dead battery in 7 hours previously.
Time will tell if it keeps up this well.
By the way....Thanks
So basically you're saying people should drain down the battery to 1% or so and not to 0% (device dies when battery is out) to get a better battery strength?
Seems to be the general consensus. I'm still not sure if that's what made the difference for me but previously,I would put my device to standbye when I went to sleep at 10:30pm and it would be dead by 6am
These issues started up when I was on slimbean ROM and franco kernel r102, but I don't think its a software issue. My phone would randomly reboot at around 70% battery and sometimes around 20-40%, and when it would restart it would show 5-10% battery and sometimes wouldn't start because the battery was completely dead. I recalibrated the battery by removing the battery bin file after a full charge and did all the necessary steps to do it over and over again. When that didn't work I did a full wipe and flashed stock factory image. I even recalibrated battery again, and now the phone shut off over night (5 hours in according to the battery stats), and when i turned the phone on again it showed 10%. I'm scared my charger sometime down the line messed with the micro usb port and shorted my battery or something.....whats even freaking weirder is that I would have auto rotation screen issues where when I would plug my phone to charge, auto rotate wouldn't work even if i enabled it, then would start working again randomly....any help would be great before i drop another 300 on a new nexus.
I, like many other A2017U users, have experienced MASSIVE battery drain the last 6-8 months, seems to be an issue with N. That has been manageable as I don't do much away from charges/battery packs. Annoying, but manageable.
The last 3 weeks or so though, my experienced has changed drastically. I have tried this on a few different O roms, different bootstacks, multiple different dates of roms, etc.
If I restart the phone when the charging cable is in the phone, battery percentage stays consistent after boot. As in, if I reboot with charging 70% battery, it will boot with 70% battery.
If I restart the phone when not charging, the phone boots at anywhere from 2%-5% battery. As in, if I reboot with 70% battery, it will boot with 2%
When looking at this via TWRP, even though Android is displaying 2-5%, and autoshutdown due to low battery, TWRP displays battery anywhere from 60%-80%.
Now here's the kicker...If I am not charging, reboot my phone (so it says 2% battery), boot into TWRP, then reboot system from TWRP, battery stays back at that 70%ish.
I've had the phone for like 19 months, so battery degradation most likely is present, but what could be causing this? Software, Hardware, or a combo?
You dont restart your phone while charging dude,you can maybe sometimes but not always like you mention.Stop charging when u reboot or are flashing.And if you did a full clean flash,you want to charge when you got it rebooted for second time! ( flash,boot system.setup google etc,setup magisk,reboot system,charge) i also recommend to put the charger on the phone when its awake (with screen on,when charger is plugged in u can turn off screen).Its because bad OS or software,or host using it wrong
Hello, i have an SM-N9005 and have always thought it was some kind of software glitch.
Now upgraded and tested several Nougat and Oreo Mods and same error. Running on RR 8.1 Mod
Even when fully turned off the battery drains 6-8% per hour.
If I take it out OK
But then when installing another fully charged battery the phone will not restart until a power cable or power bank is connected for a few seconds so it lights up the charging meter. So I can't just take out the battery overnight or while travelling
I just very annoying. Have replaced the power connection socket but same after that
Also heats up badly with CPU up to 65-68 C or more but has now turned down clock speed to test
Test with a stock rom only .
But reads to me as a problem on the motherboard .
I have similar issues. Any resolution software related?
