Hi all,
I've been having issues with my phone lasting nowhere as long as my girlfriends identical one,
I installed Quick System Info on both phones, Killed all tasks.. Not only is my display duller than hers on the lowest setting using the power control widget but the voltage on my battery is 3737mV while hers is 4071mV..
Is this cause for concern?
Update, forgot to mention, this is from a full charge on both handsets.
Sounds like your battery is fu#ked!
There seems to be an issue with the way android reports the battery voltage. If I leave my phone on the charger until the light goes green and the indicator says 100%, the voltage will often report between 4.146v - 4.156v.
Upon unplugging the phone would drop to 99% and 4.125v almost immediately.
I noticed the other day that after leaving the battery on the charger overnight the voltage was reporting as 4.206v and I was able to use the phone for over 15min before it dropped to 99% from 100%.
Minimum voltage before your phone powers off is around 3.6v - 3.650v. So 3.737 is pretty close to the cut-off point. The OS is may report 100% charge but your battery is not holding charge.
I had a battery on a different device that was like this. The battery had collapsed. I could charge it for 24hrs and it would not make a difference. Within 30min of use or 1 phone call it would die.
Does your battery have any bugles, bumps or protrusions? This is often a sign of a collapsed battery.
Edit: Don't write when you're tired, silly things come out of your fingers! Soz!
have you tried to swap batteries between the two phones. That will exclude either your phone or the battery from being faulty.
Yes, after scratching my head for a few days I did eventualy come up with the genius idea of putting the battery from the other phone into my phone!! and after charging it up, set it down for an hour and then checked and the battery was on 98% !!
So it looks like there is something wrong with my battery, This morning I woke up and my phone had been charging for 7 hours and was fully charged, I looked at the battery meter and it said 100%, I turned the phone off then back on and checked again.. 90% ???? WTF ??? just from turning the phone off and on?
I'm still relatively new to the whole android platform. Evo being my first. Why does the evo not sleep when charging? I have the issue of rapid battery drain when I unplug the phone from 100-90 in a matter of minutes. This bugs me to no end. The only way I am able to get around that is to watch for the phone to ding 100 and immediately unplug it and turn it off.
I believe that, and (correct me if im wrong), if your phone is awake, it is being used to its full capacity all of the time. CPU is running and doing whatever it does that drains the battery like it does when its unplugged and being used by the user.
Since the phone doesn't trickle charge it stops charging at 100% until it gets down to ~90% (all the while still reporting that it is at 100%). It stands to reason that if the phone doesnt sleep while its on the charger, its using this cpu power and this is the culprit of the rapid battery drain, and to that end, the culprit of a lot of people's battery woes.
food for thought i guess. that's my take on it.
There are numerous discussions about the charging thing. Search, or at least Google. The most intriguing answer I ever saw to this was that the charging system was set up to protect the Li-Ion battery from degradation by not cramming it full of charge all the time. (The OP on that was a bit more technical, but you get the idea.)
If it bugs you that much, you could root your phone, flash a ROM that is undervolted and compatible with SetCPU, install that, and then set a profile up so your phone is underclocked when it's charging / charged.
I searched xda prior to posting specifically about sleeping while plugged in. My query isn't neccisarily about charging bit rather the sleep function and awake state of the phone while its pretending to charge.
I'm curious as to whether this is hardware related or not. For example when the phone reaches 100% and stops charge could the phone then actually begin to sleep. Unless its physically impossible for the phone to sleep while there is a usb chord plugged into it.
A little test I did with this over the past two days. At night I charged to full and took the phone off the charge and went to bed. I woke up and only lost about 4% all night and was able to use the phone on the way to work never going below 90%
The next night I left the phone on charge all night. Wake up take it off the charger and within 10 minutes I'm down to 92%
Keep in mind I'm not blaming charging on this. The first night lasted longer off of the charger than the night on the charger simply because the phone was allowed to sleep through the night.
I could be wrong
you can set the options it will say 'screen stay on while plugged up' or something to the like
or when you plug it in, just push your lock button (the top power key)
also you can get a brightness widget and put it on your home screen. that way you can still have your screen on while charging but it will be dimmed or whatever setting you set it too.
hope this helps!
Your screen being on vs off while charging does not factor into the asleep vs awake time of the phone.
for an example of this, a freshly rebooted phone on the charger, with the screen off for 5 minutes, will have an "up" time of 5 minutes and an "awake" time of 5 minutes.
this is true while the phone is plugged in and the screen is on or off.
simply put, your awake time on the phone is always going up as long as the phone is plugged in, double this with the fact that the phone stops charging at 100% and you have constant drain even when plugged in.
the phone shuts off at 100% to protect the battery. If you want your phone asleep then turn it off at night. that is the only way to put the phone to sleep try searching app market. Other then that the only other way is to push the power/lock button at the top
Mobile internet fail. Sorry double post
Wondering if anyone else has had any battery issues? I went to sleep last night with about 85% or more battery, and 5.5 hours later my phone was dead....when i plugged it in for like 5 minutes to call my work and tell them i was going to be late...when i got to work my phone said 45% phone idle and 45% cell standby for battery use
none here - took phone off charger about midnight, this morning after alarm rang for the full 10 minutes, it still showed 100%
i've been watching it and am really impressed with battery life - is it possible you've got a program running in the background? - i had Startup Auditor to stop apps in the background but had that from before, on my Vibrant
on the vibrant,running a predominantly black wallpaper, screen brightness at 13%, putting phone in "airplane mode" when i sleep, keeping GPS off, data sync off etc, it'd be down to 17-22% at end of day before going back on charger
this G2, running live wallpaper (thunderstorm), no efficiency moves (ie GPS off, etc), screen brightness at 50%, phone still had 34% last night before going back on the charger - and the battery has not "conditioned" - i noticed on the past 2 phones batteries life got better after the first few weeks of use.
Nothing different than my nexus...and i was thinking maybe it was a game but that should have been killed automatically and i dont think it would say phone standby and cell idle if it was an app would it?
tonite you might try putting the phone in airplane mode when you go to bed, and turn off GPS
see what happens to battery drain overnite - if it diminishes then i'd look at what apps you've installed. there was an article on engadget not too long ago that some researchers had analyzed the 358 most popular apps, and found 30 were reporting data to their "mothership" that had not declared it or asked for permission to report data.
hope that helps
well another weird thing is, that when i bought the phone and brought it home, usually it comes with half battery and thats what it showed but i had to charge it quick with no apps really installed on it yet...Im charging now and will test to see what happens with battery...i just removed off alot of my apps.... to see whats up
I'm getting about 10 hours with regular usage though I wish I knew why Photobucket keeps starting everytime i kill it.
I hope you guys charged the phone fully before you used it first. That can play a big role in battery life.
I got my phone yesterday and haven't done any calibrations yet. I've been playing with it like you normally would if you buy a new smartphone. I took it off the charger around 9pm last night and at 7:32am right now I have about 60% left. So roughly 10.5 hours later and I've only lost about 40%. I'm very impressed by that. My vibrant would have been dead by now, it rarely lasts through the night if its not on the charger.

What's your time with out signal, sounds like the 50% bug to me, google the airplane mode fix, if not you might want to look into a new radio, and you should allways recal your battery after you flash

what do you mean time without signal? and cant flash the build or radio without root(if thats what you meant) im fully charging it now and removed all of my apps...and going to see what happens from there
I've been using mine off and on mostly text, web and speedtests for 4 hours off the charger and my battery is at 91%

Hi,
I read somewhere that you shouldnt play games on your hox while its charging, (or any device for that matter) but then i thought there cant be any truth to that or you wouldnt be able to use your laptop while its plugged in.
I normally only charge my phone at night and while its charging i generally play a few games or browse the web in bed before i go to sleep (this can sometimes last several hours if im really into a game).
Recently ive been getting the green/red LED notification light, which informs me that my phone is too hot, at which point i pull out the charger, wait for it to cool down and plug the charger back in. This is now becoming very common, and i get the LED notification after about 10 minutes.
Have i ruined the battery?

It is not recommended to overheat your HOX ... the processor is safe, but not the other parts of the phone. Just dont do it until we dont receive the next update (2.xx.xx) that solves the overheating problem (thats what i read from guys that already thesting this leaking unofficial update in a custom ROM.
Just dont do it if you want to be on the safe side
Ah that makes sense. My old phone definitely overheated and developed yellow spots. I'd game a lot with it plugged in too

Is there any official word from HTC that says shout battery charging when running games or navigation software?

This is what I would like to know.. if we have an automatic protection to prevent the battery from over heating by stopping the charging process and if we also have no word from HTC about it so I have every right to consider myself in the safe zone.. if something happens to my device because of overheating no one can say it is out of warranty
My concern is using phone as navigation or for gaming during charging - I can't imagine this phone working whole day as navigation because of overheating of battery... So I cannot do what I want with my phone because:
1. Battery drain is heavy during nav/gaming, so I have to charge, but:
2. Charging when nav/gaming will cause overheat and it will be stopped, so I will not be able to use phone as I want
As stated above it would not be advisable to play while charging.
Sad isn't it? The battery drains pretty fast when you play some GPU intensive games, and you end up not enjoying
If you can get a good kernel and manage your battery wisely there would be great improvement on your gaming time.
If you can play while unplugged with lowest brightness that would definitely help.
my 2 cents
If I can play in my mind I will not drain phone battery...
My doze doesn't seem to be activating at night. Moto display turned off. I'm losing about 10% while sleeping which seems like a lot considering my s8 plus lost about half that with always on display on...
I'm also losing about 7% per hour and getting about 3hrs screen time per charge. I noticed a decrease in efficiency possibly after buying and using the Incipio wireless charging battery moto mod.
You can't judge battery drain from 100-90% once it goes below 88% that is when you get true readings. If you unplug your phone at the high 90's the charging algorithm could have had it at 92% and over those hours it just equalized itself.
I.E. I had my phone at 99% charge on the charger for an hour or two while using. The phone will still show 99% but the battery isn't getting a trickle to stay at 99% it will not get power and drop to roughly 91-93% depending on kernel then charge back up to help battery longevity but the system will still show 99% to not make the average user freak out over their battery level dropping while charged. There was a in depth post about this years ago on this site. Too lazy to search and post, but it is a simple search.
Edit: here you go, found it. It's a great read.

It is a good read but not really what I am talking about. I never leave my phone on my charger at night. I charge to 100% before I go to sleep and sometimes I use for hour or two before bed. So the drain I am experiencing can't really be related to a false reading due to changing currents after a long time on the charger. Sometimes it's down to 70-80% by time I go to sleep and I am still losing that amount in drain. Dozing doesn't appear in my charts at all at night so it appears the phone is never truly dozing... But hey, I'm not a genius about all this, I just know it's not dozing and my cycles in gsam suck for an 835 processor phone even taking into account the smaller battery.
My buddy just made a good point... If I am sleeping with the battery mod connected, even if it's not "charging" maybe the connection makes the phone"think" it's charging and not doze? I'll have to test that tonight.

That makes sense and I was just going off the image showing 100-92 drain. I wouldn't have a mod on if you're not using it, it can cause drain.
