Another critical bug on the universal :-(

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.

Extend Battery Life?

I found something for the Desire, Evo 4G and Droid Incredible where they said that you could increase (sometimes double) battery life by doing this:
Turn your device ON and Charge the device for 8 hours or more
Unplug the device and Turn the phone OFF and charge for 1 hour
Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well.
Ok, this is strange tricks, but many people said that it’s really works!
Anyone know if it works?

How about trying it for yourself? I severly doubt it will double your battery life. It's usually recommended if your phone battery isn't fully charging or you notice your device draining rapidly. This shouldn't be a problem on a new phone with a fresh battery.

Tried it, did nothing...
Charged my phone @ 100% at 12:00AM, switched off Internet Connection, kept it until 9:00AM and battery was 72% in the morning!!!!!!!
Very very strange, my HTC HD2 running Android is much better than that????
I'm sure there should be somthing wrong with the device or the ROM????

Yes, something is wrong with your phone. No data connection and you still used 28% overnight? Very wrong. What did battery stats say used your battery?

In flight mode my HD2 used to be able to occasionally chew through ~50% battery in 9 hours our so it's usually down to a background process or app using up the CPU's free cycles.

Exactly. And using battery stats and 'Spare Parts' it should be quite easy to figure what it is.

will test it tonight.
I experienced, that Visionary drained a lot, so after perma root I deleted it, and using MoDaCo custom ROM helped a lot, I can use my phone a full day without charging, previously I couldn't as I listen to music a lot.

I tried to do the battery calibration yesterday, but there really is no point because when you turn off the phone and plug it in the led goes green instantly so it doesnt charge it anymore. I dont understand how this could do anything.

let me ask one question
how do you charge it when it is turned off? mine turns on every time and boots into recovery
EDIT:
I did it as much as I could, but I can not see a big difference

Fast battery draining even in deep sleep Possible Solution

Hello in these days i having facing fast battery draining even in deeep sleep, but after some research i maybe found one solution its very simple:
1st: Charge your phone until 100%
2nd: Turn off and pull out the battery for 2 hours or more
3rd: Put Battery and Charge your phone again until 100%
4th: Remove battery wait half hour or more
5th: Put the battery again and charge the phone until 100%
6th: Repeat the process until when you put the battery the phone is charged at 100% or a little less when this happens make a battery calibration with this app https://play.google.com/store/apps/...xLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd or a similar one, or in cwm wipe battery stats
Please if the post if repetead delete
Share your sucess or completly fail
For me works im about 1 hour with phone connected (deep sleep )and only drops 1 % before i made this "recalibration" my phone drops about 5 or 6 % in one hour after 12 hours almost all time in deep sleep a little time in wi-fi and one little call and only drops until 90%

My battery is crazy.

Howdy!
I think my battery is fooling me around.
Quick context:
- It's a Galaxy Tab 4, 10.1", model SM-T530.
- Android version 5.0.2.
- I received it at Chirstmas in December 2014. I barely used it until June (by that I mean maybe used it 5 times for 20 minutes). The point I'm making: I did not overwhelm or overuse it.
The problem:
I've just opened my eyes and realised some oddities... And since yesterday, I'm "actively investigating" my battery, reading a lot and "gathering data".
First thing, battery strangely draining:
Today when I switched on my Tablet, it was a 65%. I used it from 12:51 to 12:59 and it was then at 52%. I was just playing a game called "Final Fantasy Record Keeper" which does not seem to be too heavy (regarding the graphics). I put the Tablet to sleep by pressing the power button as usual.
Then I had to leave, 30 minutes after, I'm at my desk, I take out the Tablet and it's now at 42%. The tablet was in sleep mode all the time (I have a password so it wasn't possible to switch on and stay on).
I play some more and decide to use a stop watch. The battery drained from 42% to 15% really quickly, with on average around 30 seconds between each percent.
I put the Tablet to sleep again.
A couple of minutes after, I check and it's at 11%.
It takes me 30 seconds to get the cable and plug the charger. Before I plug the Tablet to the charger, I can see the battery percentage plummeting 9%... 5%... 4%... 3%... In a couple of seconds...
I plug the Tablet in.
3% to 5% in a glimpse, 8%, 9%...
Second thing, battery strangely charging:
After 1h09min, it's at 66%
After 1h44min, it's at 72%
After 2h15min, it's at 78%
After 2h46min, it's at 81%
After 3h20min, it's at 84%
After 3h39min, it's at 87%
After 4h09min, it's at 90%
After 4h21min, it's at 92%
After 5h10min, it's at 94%
After 5h18min, it's at 100%
As I don't use my Tablet often, just for hobbies, I generally just put to charge overnight and I never really checked the charging speed.
This is the first "set of data" I can provide, I will definitely look cautiously into that in the following days, hopefully under some insight from you.
Note:
I was all day with Wifi on. Even when it was charging. Everything else is off. And when I use it, the brightness of the screen is always on the lowest possible level.
Thank you very much for your first diagnosis!
Have a good day/night,

I also have that tablet but the 530nu variant and i have similar issues and even weirder i just shut it off as it was at 5% plugged it in and it said 0% charger on the powered down battery screen. Turned it back on not 2 minutes later and magically it was at 93%. Just to summarize it went from 0-93% in ,literally , 2 minutes of charging and while writting this and a few othet things, about 10 minutes since powered on its only dropped one percent. How do i access the system battery files? I am rooted so i can get into any file i want.

I have SM-335 and I have been trying to charge it for the last two days and all what I managed to achieve is 56% I have not been using it, mostly trying to get it fully charged. I noticed when checking the battery usage that WiFi was draining the battery, even when switched off to charge!!!! The other functions, like mobile network signal is constant and off when the tablet is off but WiFi bar is solid, even when the device was off. Charging is intermittent too although the cable was connected most of the time.... Next step I try is hard reset but this can't be the only solution

I had that problem on my t535. From 100 to 0 in 2-3 hours. Then when i turn it on after some time, it shows 1% but tablet works for about 5 hours on that 1%, or if i connect charger without turning on it shows 0% but when i turn tablet on it shows about 90%. I asked Samsung for new device, and i got it. Now is different story, my 6800mah battery charges in about 3:40-4 hours, and lasts about 9-10 hours(screen on time). I think thats hardware problem, because they wouldnt gave me new device if it was software problem.

Moto G4 battery dies extremely fast

Yesterday, my battery was running perfectly fine. Today, the battery goes for about 10 minutes on screen time. Getting it charged from 10% to 100% is very quick, maybe takes about 10 minutes. But going from 100%, it can discharge at about 5% per minute, regardless if im using it or not. When I was at 70%, i tried to restart my phone to see if it would fix it, but when It was going to turn back on, i was greeted with the low battery sign, signaling that the phone wasn't able to turn on. 70% = No Battery? Battery drains by 2% per minute when screen is off.
I'm running Lineage OS 14.1 official rom with magisk. Please help.
GSam Battery Monitor Says that 60% of battery is consumed by "Kernel (Android OS)"
Many times i have watched my battery go down multiple percent in a matter of a second its really scary

Your phone needs to re calibrate the battery. This is probably the bit I like the least about these phones. Near as I can tell the best method is to let it drain till dead - then plug in with your charger and leave for several hours. Power on while phone is still plugged in - let it continue charging another hour.
Use normally. You may need to repeat this a few times.

I've done that about 4 times. It didn't really make a difference... then I used a battery callibration app from the play store which didn't even require a full battery drain or charge and it worked very well... weird.

What app? willing to try next time I have the same issue (about every couple months it would seem)
