Hi all.
When my i-mate reach arround 20% of the main battery it shut down without any previous notice about the low level ad so...
Any idea arround there about this misbehaviour?
How old's your battery? The power level prediction might be being caught out by an unexpectedly dying battery, if it's not in optimum condition.

My device is now 2 years old and last summer, I had a lot of battery related problems even it showed that it was still 45% full. Device would shut off in the middle of a call.
Mine did the same lately. After re-connection powercable after it finished recharching for a few times, thus making it recharge a bit longer, it seems to work.
Happened to me too. Every time it reaches 40-50%, it shut downs by itself if received a call/sms.
I've been using it for almost 2 years and sometimes I left it overnight everyday to charge fully. Is it because of the battery performance has been dropped? Once my battery vibrator vibrate very weak.
I had the same.
My advice:
Clean the contacts of the battery and in the phone with a soft cloth. Recharge.
If this doesnt work then your battery is worn out and needs replacement.

I just found another painful bug....this one is related to charging (battery). I normally put my qtek on charge all through the night when I go to bed. For the last 4-5 days I have been unplugging the device when it showed 100% charge, put it on standby (no wifi,btooth,gsm etc.) and made sure there were no applications running. I usually leave it in the standby state for 2 hours while I finish my morning exercise.
whenever I return, I see a power loss of 20%!! I was shocked to see how I could loose 20% in 2 hours ith my device on standby mode. this time, I even made sure I pressed the power button before I closed the lid, and still...no luck :-( I still lost 19%
I guess the problem is, when the charger is connected and the battery gets completely charged, it stops charging further. I guess it reaches a fully charged state within 2 hours, and the battery starts to drain all through the night...and wm5/htc don't start charging once again when the levels go down....i'll have to do a cuple more tests until I can totally confirm that this is the bug...until then, are anyone of you guys experiencing the same problems?
Another thing I forgot to mention, once again I charge my battery from 80% to 100%, and it lasts through the entire day(12 hrs) and drops to only 40% with highhh usage (bluetooth ON throughout, gsm on with 3hrs talktime, and some light gprs usage). so it really is not a problem of my battery as I see it!
Cheers,
San
Hmmm. I hate to say, but I don't see that problem. But I do have the unlocked JasJar Universal from HTC, not the qtek. If this happens with other qtecs, maybe they load a custom software that is acting up. In fact, I could leave the device on for two straight hours off a 100% charge and I don't think I'd lose 20% unless the phone was on too.

have you tried charging your device for well over two hours before unplugging? (around 8-9 hours of charging for instance?)
I don't really think it has anything to do with the qtek rom/device. the qtek rom has the least ammt of customisations on it...
I still suspect that the charging process halts and it starts to drain the battery....but the os doesn't reinitiate the charging process once again....hmm
I'll have to wait till tomm before I can do another round of checking....tomm, I want to charge it....and before I unplug, I'd remove the battery and put it back and see what it indicates...I suspect that the power would have already dropped to ~80% by then...that's the only explanation I can think of at the moment....

Hi Dreamtheater!!!
I exactly follow you as far as charging is concerned and I hv a Jasjar....just to inform you...I started charging yesterday at 11.30 PM and just got up to see the charge..it is 100%...no power loss...

it shows 100% for me too...but in just 2 hrs, it drops to 80% which is weird! from then on, it drains normally...
I still need some time to nail the exact cause for the problem...hmm!

Hey dreamtheater, I charge my Exec overnite everynite just like you. Usually at least 7 to 8 hrs everynite, but I have yet to experience what you mentioned here. My Exec always start fresh from 100% and by the time I get home at nite, it will drop to about 70% so no, I'm not getting the batt drain issue like you do..
I did not experience any such behaviour with my Qtek. It charged fine over night and had 100% battery when unpluged.
Are you sure your's does not wake up for some reason after you suspend it?
Dreamtheatre, I charged my XDA Exec overnight (7 hrs) and after 2 hrs with GSM/UMTS radio on the unit lost 5% battery charge.
@DT,
You need to set the device to switch off after a specified time interval. This can be done by going to start>settings>battery>advanced and check the device timeout box. I usually set it to 1 minute.
Last night i was browsing on my JJ and fell asleep while doing so, IE and notes and inbox applications were still open. When i started, the battery level was 93%, i browsed for about 10 minutes over Wifi before i fell asleep. The device shut itself off and when i woke up the battery level was 82% which is prportionate to my 10 min WiFi use and probably 1 minute standby time before it shut itself off.
Try it out, i'm sure you will stop seeing the massive battery drain
Cheers.
Another thing. Contraty to what people think, keeping the universal's battery topped off improves battery life. Prevent it from dropping all the way to say 30% or so. You will notice the difference in battery life in just about a week or so
Another source of battery drainage i've found is when i'm charging my Exec from the USB connection on my PC - If I leave my Exec connected and put my PC into standby, it will literally suck the life out of the battery over the course of a few hours!
I think some of you have got me wrong...let me restate the problem...
I charge all night
Wake up with 100% charge
Pull off the charger
Leave it on standby for ~2 hrs (no apps running, gsm, wifi, all off)
Come back, and find a ~20% drop
Back to my findings now.......
Another morning, no luck :-(
It had 100% charge...I pulled off the battery, put it back in and restarted....still showed 100%, so I guess it really was fully charged after all. This time I turned off receive incoming beams as well....left it for a couple hours, and was disappointed to see 82% when I got back :-(
However, through the day I get excellent battery life....all day's use ends up consuming roughly 30-40% charge which is excellent compared to my prev xda2 which would comparitively loose all of it by eod. I guess if I park my device in flight mode it tends to start draining quickly....now that's my only available reason or cause that I can think of....
tomm I guess I won't put the device on flight mode and leave it just On instead. This is weird because its just me having this problem :-(
San
PS: I'm using the regular ac charger itself for charging...hmm
DT, I disabled PowerSave and switched off the GSM/UMTS radio on my Exec. After about 8 hours I had lost about 30% charge. So your 20% does seem high. It could just be the battery as loss of charge is not linear. Why not let it drop to say 60% and then do your test again. By the way there spare batteries seem to be available now for the Universal.
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..
So I have the neon400 from bell, have gotten a battery exchange once now because I figured I had a bad battery,
Battery life is roughly 4-6 hrs with minimal usage. which is terrible, With normal usage (about an hour of talk time), my battery is dead within 3 hrs.
I turn off bluetooth, as i heard it was a battery drain, unfortunatly push mail is on, and activesync for ms exchange.
Should also note that I have msn running pretty much all the time, but even with the above, i should still have a longer battery life....
Anyone can make any suggestions to improving battery life on my phone?
low life
I have a rechargable drill and flashlight set and on the instructions it states NEVER CHARGE A HOT BATTERY so I took it one step further and put the battery for my cell phone in the freezer for 10 to 15 mins before charging the only problem with that is. The battery sweats water when it comes out and you can cause water dammage to the phone and battery. I put tape on the battery to protect the contacts and wait untill it stops sweating before puting it in the phone to charge. Also, I cant say for sure with your phone but with my nokia 6275I phone it was using the battery during the night probably sending usage information to the service provider so I removed the batttery each night. After breaking in the new battery by giving it a full charge and waiting for it to be totally dead before charging (you must always do this). And cooling before charging and removal each night my battery was lasting for seven days yes SEVEN days. Mostly because no one was calling me and I was not making any other calls or using the phone in any way. Yes the phone was turned on and all other settings were off like infared and btooth. Also the phone was entering into low power mode at the end of battery life
soo good luck

I've noticed the same thing. I don't use my phone a ton, and usually every day it's charged into the computer.
However when I unplug it after work on Fridays, by Sunday night, the battery is dead....this after being in low power mode, and not being used much.
It would be so nice if there was a replacement battery you could buy that was better...
I have some issues related to the battery. Not sure if they are related.
About half the time, the battery drains itself. The machine does appear to turn off, but a day later, the battery is empty.
This does not always happen, sometimes I can use it for days.
Also: sometimes after charging and unplugging from the computer, the charge light does not go off.
I have replaced the battery two times already, but that does not help.
What can cause this?
You can try flashing another ROM, some drain your battery faster
Normal usage may last you a day or 1.5 day
Well, what is "usage". Even when it does nothing it just drains. It didn't do that when it was new, and as I said, it doesn't do it all the time. Sometimes it works even after a week, sometimes it is dead after a day.
Your UNI has a short circuit, this is the reason that the battery is drainning, maybe you use a over voltage charger morre than 5 Volts and crap the charge center circuit, sorry man your UNI is sick and soon death.
So for the past few weeks my battery has been draining faster than the speed of light. It will get to anywhere between 30 - 70% (usually about 56%) and it will just turn off. Like straight to dead, no powering down.
When I try to turn it on again I get a white screen with a picture of an empty battery.
If I plug it is, I get the charging screen showing a battery percentage the same as it was when it crashed.
I've done a factory reset, wiped the cache, tried it with no third-party apps, all sorts. But it's still the same. I'm having to charge it 4 or 5 times a day and it's only getting about 30 mins of usage before it dies.
It tends to happen the most with the camera or Snapchat but I don't think it's related to those as it will also do it in other apps and even the lockscreen.
Is it time to call it quits and send it to the phone shop in the sky?!
I had this weird problem with my battery too! MXPE on stock nougat , as soon as I charged my phone to 100% and plug out it used to drop below 80 in 2 minutes ! and then when the percentage hit ~20% It used to turn off showing that white screen you mentioned, however when I plugged the phone in it would start charging at ~15% ! so I tried recalibrating my battery and it is surprisingly effective !
here is the method:
1) drain your phone battery until it shuts down.
2)power it on again and you will see that white battery low picture. plug the charger for 3 or more seconds and out, it will boot up again but as soon as the Rom boots up the phone will die again . do it multiple times.
3)charge the phone while it is off until 100%. turn it on and drain the battery as fast as possible (max brightness, volume, streaming videos on cellular data and running benchmarks will do ) till the phone dies again.
4) repeat (2)
5) charge the phone up to 100% while it is off ! and there you go your battery is recalibrated and good to go!
Obviously, this will shorten the batteries lifespan but since I believe you have it for a long time It won't be an important matter!
Thank you. I think I'm going to bite the bullet and treat myself to the new OnePlus 5T when it goes on sale tomorrow but I will try your advice as this will be a good backup phone to keep for emergencies as it's not worth much to sell on or trade in.
Try removing the back with a heatgun and unplugg and plug de battery.
I'm having the exact same issue and tried the same solutions, no help. It's dying now after a couple minutes. I'm carrying around a battery pack.
Seems to me my troubles started after updating to Nougat. You?
