[Q] battery drain while switched off - Omnia 7 General

I noticed this a couple of days ago: I was in a place with no 3g nor wifi so I decided to switch O7 off. In the evening I switched it on and battery was empty.
I tried again yesterday with the same results. What"s using this phone while it's off?

Are you sure it is actually flat?
My battery has a problem, if i turn the phone off and then on it will show that my battery is empty and want to turn on battery saver. If i keep turning it off and on and mess with the battery contacts it reads properly.
Just a thought....

This is because the battery is cold, let it warm up and it will display the correct level

This happens after being on for days, it's not to do with temperature.

It also happens to me. Not usually but once every 1/2 weeks. I've been looking for a solution and the only one i found is switching off and on again until the battery level is ok. However i have to say that this has been happening since i installed 7740 update, so maybe the problem is that.

not actually drains...
I think the battery did not darain.
It is just the battery level is not displayed correctly; I had the same (or similar) problem. I switched off the phone while the battery was at 80% and the next morning when I switched it on I got the message "the battery is low..." and the wrong battery level displayed.
I kept it on for hours and it worked nicely; I noticed the battery info displayed 1% of residual charge and 7 hours of expected workng time...something weird
Suddenly after hours of usage the battery icon started to work properly.

Exactly the same as me. I'm on my 2nd Omnia handset now (warranty replacement) and this one does the same so I assume it's the battery that's faulty.
If you leave it on long enough the battery meter slowly increases over time until it reaches the true value.

Just installed 8107 upgrade via cab; let's see if problem have been noticed before and solved now

I noticed this problem also. After the mangu upgrade it is not there any more.
For me it seems that th eproblem laid in the firmware..

funny, I'm not the unique
Today I've tried to make an hard reset to see if the problem would have been solved. I'm on Mango 7740, tonight I'll try to switch off the mobile phone after charging.

I did a hard reset, OS update and then a handset replacement and the problem is still there.
I'm convinced it's a fault with the actual battery.

Ok, I yesterday evening I switched of the smartphone for some hours... Then I turned it on and I saw the"popup" which told me the battery was low.
I left the device on, with 3g on for all the night and this morning I found the battery level as it was before yesterday evening
I confirm the battery do not drains when the smartphone is turned off!

As I already said, this is because the battery gets cold when you switch off your phone, and it then appear drained. After heating up again it will recover it's charge.

Another battery drain problem - driving me CRAZY!!

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

Battery not charging to 100%

Been running Android for over a week now and this morning when pulling the phone of the charger I noticed it was only at 89%. This is from a full overnight charge.
Got to work and it had dropped to 85% (Watching videos) and plugged it into my laptop at work and it again only charged to 89%
Anyone else had the same issue. Will cut back to Windows to see if it goes further.

Hello dude!
Try removing the battery, wait a few minutes and put it again. See what happen.
Sometimes it is a error when the driver is "reading" the battery settings/status.
Hope it help!!
Same with me, only 90% with all night chage
Same here mine will only charge to 93% while charging overnight
Rebooting into womo and it then proceeded to charge to 100%.
Not a major but a bug that needs investigating.
also had this issue a user responded to me on the builds thread, he said to let it run down to 5% and plug the charger back in. also the one about booting to wm then back on android should fix it.
Same here at 94%. Seems to be a common problem...
Sent from my HTC HD2 using XDA App
im getting 96%.

Yes, I've got a same problem.
I've heard that no Charging-Stop exists (in kernel), so you may "destroy" your battery because it is overcharging ... so be careful
mine stops at 93%
yeah im a bit scared for my battery...ive been charging it almost twice a day now cause it dies so fast
i even have SetCPU with the profiles from the other thread, but its still draining REALLY fast...
i hope this doesnt have any permanent damage to the battery :S

where did you hear that? can you confirm?
The no stop sounds like complete nonsense. For one, it would be an obvious massive problem so the devs would have worked on it. Two, if you can detect battery charge it would be really easy to make it stop. Three, if it didn't stop, why did it used to halt at 98% for most people?

2)Battery: at current moment extended battery not supported (2350 mAh). Support of them rather complex however.
also battery working in read only mode, it's why during long android usage u can get wrong results. Will be fixed in future.
Hard reset..is only one solution
Actually _everyone_ can get this problem - after reboot u won't able to launch any external exe (exe from rom will work).
It happen because something sometimes can be corrupted during WM shutdown...
I got this problem two times Both time need to hard reset device.
So I recommend to everyone make backups!
So is it confirmed that robot voice (apt voice ) issue fixed now?
^^
confirm problem
read this before post
I have the same problem. HTC wildfire.
Try recalibrating the battery:
1. Turn off all uncessesary apps in the background.
2. Let the battery of the phone run out until it turns its self off.
3. Take out the battery for 2 minutes
4. Put the battery back in and charge the battery until it is fully charged "At least 4 hours"
5. Once it has charged take the battery out for 2 minutes then put it back in and boot the phone up
I managed
The phone was on and charging all night and it was at 97%. I turned off the phone and left it plugged for couple of hours, on and its 100%. Simples

battery at 0% then 100%

heres a weird one... yesterday i was out somewhere where i had to remove the phone battery for 15 minutes or so.
when i put the battery back in to start the phone it showed the battery was at 0% and the red light was blinking. I thought it maybe a bug / glitch so i restarted the phone by simple poweroff/poweron.
same thing. 0%
so i removed the battery - reinserted and the problem went away. now the battery reads 100% ... left the phone without charge all night and even though wifi was on i woke up to find it at 80%.
this is all running BlackFreedom_signed_007.rar
i am starting to think the problem maybe hardware related (battery) ? although the battery has been good to me lately.
any ideas/feedback?

Sounds more like a software glitch. Once you remove the battery, without powering off, you "hard" reset the phone. I would monitor it for the next few days using any battery monitoring app from the market and see what happens.

perhaps.
i removed 007 and installed Eternety 002 rom ... guess what? it read the battery correctly at 66% whereas 007 read it as 80 for hours on end.
so ya. s/w glitch perhaps.
I've also experienced it a few time Removed battery without power off, reinserted after few minutes & it showed less than 5% with red blinking light. Removing & inserting again helped

Updated from 2.2 to 2.2.1 now have Battery Issues :(

Hi all,
Basically a few days ago I updated the firmware via Kies from 2.2 to 2.2.1 on my Galaxy S. However, I instantly noticed a huge decrease in battery life - 50% gone overnight when in standby! So I factory reset the phone and had everything disabled - the phone only lost 10% in 24 hours. So I decided to try and eliminate the possible causes so first I turned on wifi and within 2 hours I have lost almost 30% of the battery life with no usage so wifi seems to be the culprit
In the wifi menu network notification is off, however, the device seems to be scanning for networks every 5-10 seconds even when connected! I had no problems like this on 2.2 where I could comfortably get 2 days usage with wifi on. Also as I would prefer wifi to be on constantly when connected I would prefer not to change the wifi sleep policy. Any suggestions would be much appreciated
Many thanks, and sorry if there's similar thread already
which version of 2.2 did you have before?
try a flash back and see what happens.
Or try to drain battery (do not charge till 1% or almost dead) then full charge it.
Always happen to me when I flash my phone to a new ROM.
Thanks for the replies. I've tried leaving the battery till it was almost drained but maybe I'll let it go completely flat and charge it see if that makes a difference?
Also trying juice defender from the market to see if that helps. Not sure if it is a problem with the firmware though been looking around and a few people seem to have had the problem with no real solution
Might have to go back to 2.2 but would prefer not to as I've noticed a big decrease in lag on 2.2.1. Also can't remember what version of 2.2 I had I'll see how the battery life goes over the next few days after trying a couple of drain/charging cycles hopefully won't have to downgrade it. Come on 2.3.2
Thanks for the replies so far
Battery Bug is Major issue with all the versions of 2.2.1, Battery life is very bad. Even the Browser is worst in 2.2.1. May be in 2.3 it will get fixed.
I have tested all the new releases of 2.2.1. I found its smooth and fast.

Very very bad idea to let the battery go completly flat, it's the best way to damage it and even lose 20% of his initial capacity. Never go under 10%.
To calibrate it properly, wait 10% turn off the phone, fully charge it, restart. (do it again 3 times).

The battery is calibrated to do this already, the charging circuit will not allow power to the device unless there is a certain amount of charge in the battery. It's there to protect the battery from this exact eventuality.

Battery stuck at 50%

Hey guys,
today my phone just didn't show any other battery capacity than 50%. I had it on my car dash charger for multiple hours. This evening it still turned off and showed the "Battery too low" screen, so I assume it did not charge.
First, TWRP also showed 50% and a very long weird number as CPU (top left), then it stopped showing anything about the battery
After I turned it off and tried to charge it, it crashed in the bootlogo and rebooted.
Any ideas what to do? I already reflashed the firmware.
Best regards
Colin
I have this problem too
Just use it till it gets fully drained then charge it?fully
Currently encountering the same issue with my OP5 now and when I consulted a tech regarding this one, he informed me that it may be a possible motherboard or battery issue. Will have my OP repaired by early January and hoping that it's only a battery issue(fingers crossed).

Looks like you drained the battery too much and the battery chip got confused. Or worse, one of the cells died. This doesn't just happen to OP5, but to all batteries.
There are a few options:
Replace the battery: https://www.ifixit.com/Guide/OnePlus+5+Battery++Replacement/103028
Turn off the phone, then charge it fully while off. Then slowly drain the battery again, in a way where the phone isn't sleeping so Android can gather battery statistics.
If above didn't work, then do above method, but also clear battery statistics in TWRP, or the recovery of your choice.
There's the option of putting it in a vacuum sealed bag, and putting it in the freezer. Google for details, and do's & dont's.
Hope this helps!
Did you get the issue fixed? Currently I'm also having the same problem
