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

[Q] Stop charging at 90%

Hi all,
My Atrix won't charge more than 90%.
Do you have a solution ?
Thank you

goto the market and look for battery calibration, when it hits 90% or so or wont charge more, hit calibrate, then drain it to 0 and charge it back and see what happens, also whats the voltage levels at 90% ?

Thank you for your return,
The voltage is 4.036V at 90%.
I will try and let you know.

Same problem here. Also when charging, the indicator is not working.

follow this guide to fix all your battery issues

The battery thing is a pain in my A$$.. this is what I did to fix it:
1) drain phone 100%
2) charge to full while phone is off
3) while phone was still charging, I pulled the battery, waited for the screen to show a question mark, then I plugged the battery back in. Then it shows the battery as 5% or 10% (YMMV)
4) let it charge again for another 2 hours
5) before turning on; I went into recovery and deleted battery stats, then rebooted
6) phone should be at 100% or close to it, if not, then wait until its at 100%, then calibrate the battery using the app.
NOW ---- after doing all this, my phone seemed fine.. then.... the problem started happening where the phone wouldnt charge to 100, then it wouldnt charge to 95, then it wouldnt charge to 90, then it wouldnt charge to 85..
of course I started freaking out like WTF -- but.. this is what I did to fix it:
I tolerated it. I just kept using my phone, charging when I needed too, etc etc etc. I never let it die completely.. i just kept charging once the phone hit 10% or so (over night mostly, and sometime thruout the day).
Eventually the percentage started creeping back up... slowly.. I noticed after every overnight-recharge, the percentage would climb up by 1. So it would goto 85..86...87.. etc. etc. until it got to 95.
Then over the weekend while I was streaming a movie on a car ride home; the phone died because I ran out of battery, I took it home --- put it on the charger without turning it on... let it charge for an hour or so, when I turned it on the phone was at 80%.
I kept charging it -- and now.. after ALL OF THAT... my phone charges to 100% . EVERY. SINGLE. TIME.
Sorry for the long post -- but this is what I went through to fix my battery. a PAIN IN THE A$$ , but I think eventually your battery will learn to fix itself.
This is from all information I found in these forums, I can't take credit for any of this.

Weird Battery Behavior + S Pen Issue

Hello everyone, i just purchased a second hand Note 3 N9005. The phone was bought 1 year ago. Everything is fine except two things.
1) Battery: As soon as i charge the phone battery drops really quick down to 80%. For example it discharges 10%+ or more during night (wifi, mobile data off), if i use the phone it will drop to 80% in a matter of minutes. No obvious reason for the drain in my eyes. As soon as i hit 80% it starts to behave more normally. The more i discharge it the harder it gets to run down the battery ! Last night i was trying to fully discharge it. Battery was down to 1% and it took 45+ minutes of youtube playback to go from 1% to empty !!! Moreover at night if battery is under 80% with 7-8 hours of sleep it won't drop at all. As soon as i plug in the phone it goes from 0% to 15% instantly ! Then it charges normally.
Is this behavior normal ? I mean the no linear discharge. I've had LG G2 before and Nexus 4 and i didn't have this issue.
If this is not normal, is it most likely a damaged battery or could it be phone's fault/ inability to read the battery charge correct?
2) S-Pen. I have noticed that it needs some pressure to work. I've tried Note Pro 12.2 S Pen on the phone and it works with a lot less pressure. I've opened the pen and increased it's sensitivity it got better but still not as comfortable to use like the S-pen from the Note 12.2. Anyone else noticed this ?
Thanks in advance for your time

Are you using the stock charger ?

Yes stock charger, stock rom no root.

Probably try a new battery for the spen have you tried changing the tip of it?

Yeah i have changed the tip. I even tried a tip from the Note 12.2 pen, same thing. I think it comes down to a sensitivity issue.

Yeah already done that ! No matter how much i increase the sensitivity it never feels the same as the Note 12.2 S Pen ....

Rockfreak I'm also having the same exact problem of the battery, my battery drains from 100% to 82% in less than 25 minutes after that its solwing down, there is a strange thing some certain percentage is hard to be drained easily as some time it takes 10 minutes to drain a certain percentage specifically i can't understand why but I believe for some reason the system is not reading the exact percentage and capacity of the battery.
However, although of the strange battery behavior I'm getting almost 5 and half an hour screen on time no matter how long I'm idle also i never close my 3g connection and it's always connected as H+.
Moreover, i tried to use battery calibration application that doesn't require root access (my N3 is not rooted) when the mobile is in the charger and fully charged notfication appears i restart the mobile without unplugging it from the adapter once it's boot i go to the batter application program and press calibrate then i unplug my mobile.
In this excact period of time i can notice a big difference in the battery behavior and it starts to drain almost normally, anyhow, I'm still getting the same excact screen on time which is around 5 to 5 and half hour, also as soons as the battery reaches 0% or 5% and i charge it again to 100% and get the battery full notification the misbehavior starts again.
I tried alot of things but unfortunately with no luck. So i decided that ignorance is a gift xD

With that amount of screen time i wouldn't be bothered either ....I'm getting 90-120 minutes of screen time maximum in under 1 day usage....thanks for the info though

[Q] Instant Battery Drop from 10% to 0%

Hey guys ,
I have a Note 4 N910F. I can't say I'm impressed with its battery life (coming from LG G3) but it lasts from the morning till I go to sleep on med-high use which is fine.
The problem that I experience though, is that if I "heavily" use my device when the battery reaches 10% - i.e. the GPS and the Data Connection turned on and Google maps are being used, the phone suddenly shuts down. I need to put it on a charger to turn it on and the battery is 0%.
I will post a screenshot as soon as I can.
Do you think this might be related to a hardware issue ? Or is it just the battery ?
I've tried to calibrate the battery but didn't help.
thank you!

Next time you should search first as there is another thread discussing about this.
But I will still answer your question.
It's your battery deteriorating.
It seems that your battery can only hold 90% of the original capacity.
Li-Ion/poly battery WILL deteriorate over time & it can deteriorate faster without proper care.
How to prevent faster battery deterioration:
Avoid heat.
High temperature is the worst enemy of any lithium based battery.
Never let your battery reach 0%
Reaching 0% means longer charging time = more heat exposure while charging
Avoid putting your device/battery on the dashboard during sunny day.
Do short charge multiple times a day.

[i9505] Charging/Battery issue.

So, i'm charging the phone to 100%, the "remove charger" message appears, and i remove it. But in about 10 minutes, the phone is at 95% already (with screen off). After 95% it goes down normally, 1% every few hours with screen off.
But, if i let the phone still charging for a couple of hours after it reaches 100%, the battery % goes down as it should. Another thing is that, while it is said that after reaching 100% the battery does not receive power (i read in this forum), using KTweaker charging option (from the kernel) i see that my battery keeps charging normally (or even at a higher mA compared to < 100% ).
I'm on Omega Rom v19 JB 4.3 TW with KToonsez Kernel.
Thank you!

The battery, over time, loses its ability to hold a charge effectively.
This happens gradually and slowly.
I've also read that it's not healthy for the battery to sit too long at 100%, which is why it drops fast to anything below that. I don't how how true this is though.
Also, if it the phone stops charging at 100%, then why does it stay at 100% for hours if left plugged in?
If it stops charging, it should drop to 99% after some time, at which point it would start charging again until it reaches 100% and stop again, right?

It's true what you are saying. I guess it could be because in 2 + years of usage the battery is starting to lose some properties. Maybe it's time for a new battery if it becomes an issue.
thank you!

Is an extended battery an option (mostly the extended ones with the same size as the original ... @ around 3500 mA)? Anyone has any experience with those?

I guess it will give you probably, almost, half a day more use time, since it gives you almost 50% more mAh.
