My hermes standby time was about 2-3 days depending on my usage. but two days ago, i charged my hermes to %100 and then i slept, when i woke up in the morning, my tytn was closed, i tried to open, but it did not.. So when i pluged the charger, red light flashed and then yellow, which means my battery was fully empty and started to be charged, so it worked again.
And now it takes about 2 hours to be fully charged, but it only takes 4 hours to be completely discharged again!!! It happened so suddenly! As i know, batteries die slowly, not that much suddenly??! Do you think there could be another problem?? Or is it just my battery?? is it possible that my battery died in one night??!
I could think of a couple of things...bad battery, faulty device, or you are just doing so much with the phone that the battery is being drained. Do you keep bluetooth turned on, and wifi, and have your phone polling for new emails every 15 minutes? That will most certainly drain the battery really quick. Also, do you have the device set to automatically hibernate when not in use? I just received a new 8525 due to warranty 4 days ago, and I have not done any modding to it yet. Off the bat, I noticed that my battery life has significantly increased.

There are causes depending on the battery and causes depending on the hermes:
Battery:
1> The battery has a certain lenght of life. This type of battery is very sensitive and can be charged around 300 and 500 times. Each time you connect the charger you "consume" a bit of the life. Nothing to do with memory effect but with the physic of lipo batteries. How old is your battery?
2> Lipo batteries can not be discharged below a certain voltage (3.00 volt per cell. The hermes battery is a one cell type). If this happens, you kill the battery (short capacity, impossible to charge,...) The pda is normally equiped with a circuitry able to avoid this.
PDA:
1> You can have running applications burning power. But you know that
2> In certain circumstances, the motherboard can have a problem and starts to burn your battery. This is a hardware problem which needs MB replacement. This problem is described in the maintenance manual of the hermes and is tested by service people when a hermes is refurbished.
You can try the following:
1> Fully load your battery and close all applications (No phone,nothing). See what happens in one night
2> Fully load the battery and shut the pda down. See if the battery remains fully loaded. If it is not the case, try again with the battery out of the phone. If the battery is partially/totally discharged with the battery out of the pda, the battery is dead.
3> See how much your phone consumes by using this application: http://www.acbpocketsoft.com/Products/acbPowerMeter/acbPowerMeter-Overview-2.html
Start your hermes without anything loaded (no phone,...) With backlight on (default level) and nothing running except this application, the level will be around 70mA (average). Without backlight, you would be around 25mA. At least this is what i get on mine (rom,... see my signature). This test is very dependent of the OS and the radio rom loaded
This will not repair your battery, but i hope this will help you to identify the problem
" As i know, batteries die slowly, not that much suddenly??!"
yes like humans batteries age and die after awhile
but all electronics like humans can die of a "heart attack" too
Thank you everyone is very helpful here Well i found the reason for my short stanby time, i am using pays rom 1.31 and there is a program called HSDPA switch, somehow when i uncheck the `Turn on HSDPA` box, everything seems to be normal again!! After a deep searching week, now i know the problem. I know its very odd, but when i re select that box, again my battery finishes in about 2 hours... Strange yep..
hey,
i have also bought this X-Level battery from Momax. I just received it one and an half week ago.
At first the battery did run very well.
I charged and discharged the battery for three times (completly) as recommended in the manual.
Yesterday, at the beginning of third day of usage without a recharge the battery status stated 60% remaining. When I have tried to do a phone call and thew other person responded my call - I could not here anything. I have tried to do 10 phone calls and received three incoming calls. The phone did not make any noise. After all I have done a softreset. Then the battery stated 1% left and my phone switched off automatically.
It noticed this " wrong battery status effect" with this battery for severall times now. It states the for example 40% for more then 4-6 hours.
After a soft-reset there are only 15% remaining.
The effect doesn't occur only in the touch flo top bar. When I go to my battery settings it states the same.
With my normal htc battery I have never noticed this effect. Since Yesterday I'm using my orginal battery again to determine if this is a battery or a phone problem. Since yesterday the battery status drains as just as normal(fast :-().
Has anyone the same problem with this battery?
Thank for your feedback in advance.
I use Monax X-level battery for 3 week, and till now everything is normal.
i bought it when it released.
about 2 months from now. everything works like a charm
longer standby than the HTC original battery
I bought the X-level momax battery as well and like eraz0r it worked for about a week and now has started mucking about.
First time I noticed was my phone had switched off, thought I had just forgot to charge it as it wouldn't switch on.
Put the original battery back in phone started up fine. Put the momax battery in and it still didn't turn on, so I connected the charger and within five minutes it was back to working and showing 70% charge. Took the charger out and it lasted about five minutes before it turned off.
Took the momax battery out and chucked it in the bin..
I did notice that there are two contacts on the original battery which connect to two pads on the phone. These contacts are not on the momax battery.

Especially his last sentence could maybe be important? I have compared these two batteries now as well. I noticed the same missing contacts. I thought of removing the colored momax label from the battery. While I had been trying to remove it, I saw that there is the blank battery behind it. The contacts on the back of the battery seem to be missing or there are 1cm above the orginal ones behind the label. There seems to be a little squared hole ????
Does anybody know the usage of this contacts and maybe why they could be missing`?
After reading this
Man dies as mobile phone explodes
I'll stick to the original battery
I've experienced an exploding battery. Some cheapo counterfeit Duracells that went BOOM one night when I was sleeping. I found the battery stuck on the ceiling completely burnt out.
I would recommend to everyone to stay away from cheapo "china" LiIon batteries.
If you don't know *for sure* that the particular brand of replacement LiIon batteries YOU are buying is manufactured to industry standards with all the necessary protection circuitry and venting holes etc., stay away from them and buy a battery made by HTC, even if it's more expensive or appears to have lower capacity.
The amount of electro-chemical energy stored in LiIon batteries is alot larger than most people expect. I for one would not like to have this happening in my pocket: http://www.youtube.com/watch?v=YCWdnjLqVWw&feature=related
(yes, this LiPoly was deliberatly overcharged but nevertheless it shows what can happen in a worst-case scenario)

ok, at first I will using my original htc battery again.
With "automated profiles" I am able to increase it's lifetime up to 2-3 days
I have also sent an email to the momax support (1 week ago). No answer up till now.
But I really would like to know why these contacts (backside of the battery when inserted) could be missing.
@mikemod: Do you have any new information on this?
Same here
I'm starting to have similar problems, the battery begins loosing charge very quickly then sticks at a certain percentage for an hour or so the again loses charge. A full charge lasts about 8 hours only. Back to the original HTC
My battery is 1.5 months old. I've emailed Momax with no replies yet.
Yes their product support sucks! There is a six year warranty but when I received a defective battery straight out of package, I emailed them twice. No reply at all. I guess i have to go to HK to get the replacement!!!!!!?
I've owned my Note 4 since October 2014 and it's been working solidly since. Last Thursday, out of nowhere, I noticed that from a 14% charge, it suddenly dropped to 4%. I immediately scrambled for a charger and charged it back up to 100%. On Friday, I charged my battery normally again. Charging finished at 11 AM but the drain was abnormally high. My phone was warm to the touch and battery was dead in 4 hours. I was using the phone normally throughout that time, 4g on, location services/bt off, screen off for the most part. I ran OS monitor to see whether any app was locking up the CPU, but, as expected, the main CPU users were Android System and Android OS.
On Saturday, I charged the phone to full again, disconnected around 4 pm. Being that I was home, both wifi and 4g were off. Battery discharged normally, and was only down to 30% on Monday morning.
On Monday, I noticed that battery dropped from 21% straight to 11% straight to 4% in a few seconds. The drain from 4 to 3 to 2% was decent (few minutes of screen on time, on viber), then the phone shut off. I tried to charge the battery with the device powered off, but noticed that the phone simply stopped charging at 80%. I thought that was an abnormality. I tried wiping the system and app caches, but the problem persisted and drain still felt pretty fast. Tuesday night, the phone stopped charging at 91%, staying at the same level for 40 minutes before I gave up and unplugged.
My friend had purchased a fake OEM Note 4 battery and allowed me to try the drain/charge process using his battery to troubleshoot. When I first plugged his battery into my phone, the drain was high at about 1 percent per minute. When I tried to charge the battery, the charge level would not go beyond 90%. I switched on safe mode, but the battery did not charge any further either. I felt by then that something was definitely wrong with my phone. When I restarted the phone to get out of safe mode, though, it suddenly started charging again and hit 100%. With regular use, the fake battery gave me 16 hours of power, which I thought was relatively decent. Alas, when I started charging it again, it stopped charging at 77%. Battery Monitor Widget showed 0 mA flowing into the phone at the time, though the battery indicator in the status bar showed the lightning bolt.
I took out the fake battery and put in my original. It is now charging up normally, but I expect charging to stop before I hit 100%.
If anyone could provide possible explanations for what could be going on and/or other troubleshooting tips to try, I would really appreciate it. A factory reset would be my last recourse.
Thank you very much!
EDIT: My battery went all the way up to 100% this time. But it's the same one that got stuck (at 80% then at 91%) twice in the past.
I'm using two different Samsung chargers and different cords, by the way, and blew out the port with air prior to attempting to charge the fake battery that still stopped at 77%.
I had the same issue, took it to Samsung and they replaced the battery, it has been okay since that

Really? I was ready to write off my battery and just buy a replacement, but what was weird was that even the newish fake battery wouldn't charge fully. That's what made me worried that it's my phone that's the problem.
It'd be great if this could be as simple as a battery problem.
I bought a 1 year old note 4,it usually dies at 25% percent,it drops suddenly to 0 %.,after weeks of research i found it is caused by faulty battery so i bought a new battery now it dies at 10% to 0% in seconds and turns off,i flashed a kitkat rom now problem is solved but i want to be on lollipop due to UI changes,can any custom rom solves this? i've tried dr.ketan rom,same issue dies at 10%...

Probably caused by battery calibration. Just use your prior rom from 100% to when it shuts off a couple of times to retrain it.
If you use multiple batteries like I do, you'll never be able to calibrate, and will just have to live with this issue.

Well not entirely true. Ur battery have the chip that tells the system how much left the battery is. I often have those prob. But now is gone. I just charge until 100% let it 10min charged. Then use it until it off. (Really really off.) Like when the battery circuit stop the battery not the phone shutting down. After that charge until 100% and after 100% i let it charge for 1hour to make sure it really 100% . done
Same here after last update. From 10 to 0% in second
+1 here
Thats why I utterly I hate sw updates.
My Galaxy NOTE 4 SM-N910C
Same problem here ,, considering buying a new battery but afraid that the problem isn't from the battery and get the same drop again with the new on
my phone is 1 year old
i had the same problem, so what i did was to flash the Rulinglite ROM for my note 4 910 C. it works fine now.
Hey guys, I got the same problem. Sometimes it drops from 15% to 4% in a few minutes and then from 4% to 1% in another few minutes (without using phone ofc).
Also, when i charge my phone - it shows me 100%, but when i reboot it - i got like 94%. Few minutes later - again 100%. After reboot - 95%.. etc etc etc... (charger is pluged on for all this time)
Do you have this problem?

Same problem here
my problem is that the battery percents are getting lower ery fast..if i make some actions that require more battery and i have 20% of battery, the percent goes to 16 so quickly and then the phone hangs up. I turn it on, it shows lesss battery, then it hangs up again and i need do recharge the battery. I bounght the phone at 2nd hand, i noticed the battery issue since i was testing it, but i love the phone. i am affraid not to be a hardware problem with one of the internal components of the phone, that killed the battery...i tested the battery on Note 3 and i am sure that the battery has a problem. What if i buy a new battery and a malfunctioning component of the phone damages the new battery too?
For me: i will dial *#0228# press quick start and wait till phone lids up connect charger and charge until 100% and then dont unplug first leave it there for 30mins or more and then unplug. ( do not unplug it halfway )
Second i switch off my phone take out battery and wait around 3 mins and then put back in and start charging it to 100% without switching device on, also same thing leave for sometime before unplug when it reaches 100%. you can also switch on after 100% and wait for sometime. ( as booting phone drains battery too )
hope it helps
Bought a new battery still drains at 10percent exactly,thought it's a lollipop issue,but even in MM it exactly shuts off at 10%.
My phone is used as a backup device and had very short , about 3 hours, standby time due to obvious age related battery wear so I decided to have a go at replacing the battery and reviving the old nexus 4.
I ordered a replacement battery off ebay (sold as OEM) and changed the battery myself. the phone was factory reset afterwards and left on charger overnight.
to my surprise it never gets above 42% and as soon as the cable is unplugged it goes nuts, drops to something like 15% then a minute afterwards it just shuts down. when turned back on its at 34% then drops again and turns off...
I have tried everything , factory reset full wipe, battery calibration apps etc without any success
any help would be greatly appreciated .
phone is stock 5.1.1 , rooted
Had the same issue, tried two "OEM" batteries from ebay, I put back my old used genuine battery. I was able to charge up to 100% but one was dying around 40%, the other around 20%.
Anyway the lifespan was really short (5-6hours) with the same drops and ups in the percentage as you described
