Hi all, i have developed this weird problem in my jasjar and i'm sure it's some settings that need to be changed somewhere and not the battery itself. When i first got the jasjar, it gave me a good 48 hours battery backup on standard use but i lost my charger and started using usb to charge it. it's since then that my jasjar drains the battery in less than 12 hours. i have tried replacing 3 batteries but to no better effect. I remember reading something about the Li ion polymer batteries having the memory effect or something and how to reset that in the bootloader mode. if you guys could help me figure it out and fix the problem, i'd appreciate it! here's the details of my rom.
R:1.13.00
G:42.47.p8
D 2.01.06 wwe
the rom is the wm6 from jwright.
(nb: i had the same problem with my shipped wm5 rom and i thought upgrading it would help but it didnt apparently).
How long do i need to use the battery to check the drain thingy. the reseller tells me to use it for 2 weeks before judging it. i'm screwed with having no battery life to this otherwise beauty of a device! if i could get any help, it would be much appreciated. thanks in advance. (josh).
Had the same problem, been happening all week, the phone would just switch of even though it registered over 80% charge. no i am happy again because i read on the forum that you need to totally discharge the battery occationally for it to get to a full charge, it appears that there is some sort of memory effect where the battery thinks it is nearly discharged, try it, i am sure you will find that it workes.

I too has a similar problem but this method did not solved my prob as my jasjar switches off by itself at 40%.
I had a similar problem a couple of weeks ago as a charge would last less than 24 hours when I used to be able to last 2-3 days.
Soon sorted it when I found that the Jasjar had decided to disable the automatic switch off, now a charge is back to lasting 2-3 days.

Had my MDA PRO for 1.5 years, and never had this problem. Battery lasted for 2-4 days on average, although now I have a 3200mAH battery it lasts for well over a week on a single charge
Lithium ION and Lithium ION Polymer (the HTC Universal uses the latter) do not suffer from any "memory effect". The only battery type that does to any significant extent is Nickel Cadmium, which is rarely used these days.
It's also impossible (well, almost) to completely discharge Lithium ION Polymer batteries - internal circuitry in the battery shuts down the cells when the charge gets too low, at up to 10% charge. This is because a completely discharged L.I.P. battery becomes unstable, broken (unable to be recharged), and runs the risk of explosion or leaking in this state. So don't attempt to drain those batteries completely dry folks - it's dangerous! Letting them run down naturally in your Universal should be safe though because of the cut-out mentioned above.
Maybe the Uni just has a large batch of bad batteries? You should also check what apps you have running on it all the time, and how often you use bluetooth and wi-fi - these two REALLY drain the battery if you keep them on all the time... Also try MemMaid, this is great at cleaning up your notifications queue, which is where lots of apps leave old and obsolete entries clogging it up.
I have the same problem. I do not know where the charger is, so I am always using the USB while syncing. I also tried 2 batteries, but they both last about 12 - 14 hours. Maybe it is caused by WM6.
I did not quite get this solution:
"Soon sorted it when I found that the Jasjar had decided to disable the automatic switch off, now a charge is back to lasting 2-3 days.

What is the solution?

I feel like I'm walking on eggs...I bought my Jasjar used on eBay just over a year ago, still the original battery. I almost never use the 110v charger, always a USB conection with my Mac, often recharging at 55-75%. I just intentionally ran down my battery to 18% (got warnings to recharge), and recharge via USB/Mac again. It took me almost 4 days to get to 18%, and Bluetooth is constantly on for ready use with my earpiece.
Curious: are the problems with original or replacement batteries? Cheers,
Update to Radio 115 or 114
It's worth taking into consideration that when flashing, you really need to have a full battery. There are reports of batteries starting this kind of behaviour after user has flashed with drained battery, then causes battery charge issues until next reflash.
IMHO even if u charge with a full charged battery still u get a prob so i think its a common issue with the jasjar and its power managment software itself by default as lot of people with diffrent ROMs are complaining about it.
no changes...
well, folks, i tried all these gimmicks but not to any definite changes ... i guess i need to consult the service center guys at last...i didn't want to do that but i guess i need to. i'm sure it's not my battery as i've replaced 3 of them...i dont kno what else to do!!! thanks for ur posts tho as i get to try diff things to check if ma battery is doing ok...keep postin...thanks...

how 2 discharge a battery >>>>>
problem with battery?
I have the same problem, it firs appear on original battery when charge was 40-50% so I have bought the same battery model (1620mAh). But it doesn't help. Now I,m using the 3200mAh battery and it doesn't help as well. The thing is that XDA switch off it self always on deferent charge level (sometimes is on 20%, 45% ar 80%...so is very difficult predict when it happen again). And one more thing...when it switch-off and I try to switch-on back, I can't (keep switching off), only slolution is put on charger!!!
I have downloaded the service manual (I think called "confidential") and it mentioned that it could be a problem with main board (so its HW problem). So can anybody tell me is a problem with bat or MB? (replacing the MB is fcjfdj$#ing expansive). Thanx.
well if your XDA does not switch on until you start charging it that's a clear indication that your battery is empty. I have the same with my faulty battery. Replaced it by a working one and it's fixed. Something is definately messed up with the charging circuit or the batteries though. They are not supposed to die so easily.

The first time I flashed the PDA I ruined my battery. This time I thought I'd be smart and I put in the old battery while flashing. After flashing I put back the new battery and now that one is broken too! It wasn't even in the PDA when I flashed it. How bizarre is that?
I have to admit I did not fully charge that new battery before flashing, but I figured it would be safe since it wasn;t in while flashing. The battery worked fine the day before I flashed my phone (got the "charge now or save your work" message), but after the flashing and putting it in, it just crashes at around 30% or 40%. The usual battery misery.
Maybe I should try fully charging it and then flashing again. Trouble would be how to get it fully charged though. I always felt charging cuts off early on the "broken" batteries (pull the charge plug and stick it back and it charges for a while again).
I managed to restore my battery to good health by completely discharging it in bootloader mode.
First I completely charged it. When the led went green I pulled the shcarge cable and connected it back again. After doing this a few times it doesn't stay orange so long and then I stopped and left the cable disconnected.
I reset the phone (on full battery) and then I set the unit to boatloader and waited for it to completely discharge. I reset the phone again (on empty battery) and low and behold my trusty "charge now or lose data" warning came back.
BTW I reset the PDA hoping maybe it would store the power levels. I remember that trick from my Palm days where sometimes you had to reset a PDA on full battery to calibrate it.
I charged it back to full capacity and started using the phone as normal. When the battery was empty I got no crash but a friendly warning telling me my battery was going low. Phew.
Will try the same with my other troubled battery over the weekend.
I have the same Issue.But , I think it's about Rom.
and I'm try a lot of ROM version ,only one Version canbe use more than 3 day.
I can't find any reason ,.
discharge in bootloader ,I do it ,But battiery is same time for used.
If my HD has 20% power left and is running program, it will always power off without low power alert after a few minutes. Then, you must recharge it for power on.
In addition, I found that the refresh interval of power indicator looks slow, in other words, after it has been charged and run for a while, the power indictator is still 100%.
Can anybody tell me the reason and how to resolve it? Thanks!
Are you using the original battery?
Battery level is rather inaccurate, especially with 3rd party batteries, so don't take it for granted.
The battery is certainly an original battery.
Is there a possibility that the issue is relative to ROM version?
I have a experience that I flashed a rom of version 21109 into my HD, the issue occured every time. Afterward, I reflashed a stable rom of version 20769 back to it, the issue has never occured. But, several days ago, I flashed the newest radio into my HD, after that, the same issue occured anew.
I'd blame the battery, if it dies when your unit reports 20% charge, it must be in a pretty bad shape. If you can find a spare battery, give it a try...
was anything more found out about this? I also find my battery indicator very slow to update....soft reset my device and lost 5% power according to the battery...I have even had the reverse effect after a charge,....soft reset after a charge and seen MORE power than indicated.
This is making me paranoid and search for every last tweak to save power but it might be that the indicator is wrong in the first place - ideas?
Charge the battery full and let it drain to zero,and one time again.this should recalibrate the powermeter.
or your battery is old and broken...if you often charge your device when its not even required the battery will loose power and be dead in a very short time.
i know my english is not the best,hope you understand what i mean
Hi all,
Basically a few days ago I updated the firmware via Kies from 2.2 to 2.2.1 on my Galaxy S. However, I instantly noticed a huge decrease in battery life - 50% gone overnight when in standby! So I factory reset the phone and had everything disabled - the phone only lost 10% in 24 hours. So I decided to try and eliminate the possible causes so first I turned on wifi and within 2 hours I have lost almost 30% of the battery life with no usage so wifi seems to be the culprit
In the wifi menu network notification is off, however, the device seems to be scanning for networks every 5-10 seconds even when connected! I had no problems like this on 2.2 where I could comfortably get 2 days usage with wifi on. Also as I would prefer wifi to be on constantly when connected I would prefer not to change the wifi sleep policy. Any suggestions would be much appreciated
Many thanks, and sorry if there's similar thread already
which version of 2.2 did you have before?
try a flash back and see what happens.
Or try to drain battery (do not charge till 1% or almost dead) then full charge it.
Always happen to me when I flash my phone to a new ROM.
Thanks for the replies. I've tried leaving the battery till it was almost drained but maybe I'll let it go completely flat and charge it see if that makes a difference?
Also trying juice defender from the market to see if that helps. Not sure if it is a problem with the firmware though been looking around and a few people seem to have had the problem with no real solution
Might have to go back to 2.2 but would prefer not to as I've noticed a big decrease in lag on 2.2.1. Also can't remember what version of 2.2 I had I'll see how the battery life goes over the next few days after trying a couple of drain/charging cycles hopefully won't have to downgrade it. Come on 2.3.2
Thanks for the replies so far
Battery Bug is Major issue with all the versions of 2.2.1, Battery life is very bad. Even the Browser is worst in 2.2.1. May be in 2.3 it will get fixed.
I have tested all the new releases of 2.2.1. I found its smooth and fast.

Very very bad idea to let the battery go completly flat, it's the best way to damage it and even lose 20% of his initial capacity. Never go under 10%.
To calibrate it properly, wait 10% turn off the phone, fully charge it, restart. (do it again 3 times).

The battery is calibrated to do this already, the charging circuit will not allow power to the device unless there is a certain amount of charge in the battery. It's there to protect the battery from this exact eventuality.

That's how it's supposed to be in an ideal world.
My Galaxy Note has been performing beautifully since I got it back in January. I typically get several days out of a battery charge - I'm a pretty light user. Two days ago I powered it off for a couple of hours. After turning it back on I made one short call, then nothing the rest of the day. I think it was indicating about 50% power remaining when it was powered off. That night, I was surprised to see it way down at 15%, so I charged it back up to 100%. I did note that I had left the Messaging application running, but that's all - no wifi, bluetooth or anything like that. Next day I was astounded to see that charge last only about 4 hours (according to the meter). Not only that, but the phone actually felt warm to the touch - something I've certainly never observed before. It was like it was running on amphetamines or something!
I was sufficiently alarmed by this to power it down again, remove and reinsert the battery, and power it up again. At that time it was charged up to about 75%. The weirdness continues - since then, about 10 hours ago, it has been almost locked on 75%. It may have made 1 or 2 calls in that time, but no other use at all. I do not have any of the power saving settings enabled, and I'm running Android 4.0.3.
So the question is - has anyone else seen any behaviour like this? Can it be just the battery monitoring getting out of sync? Can powering it down do that? It would not have bothered me too much if I hadn't felt the over-warm case. I find it hard to see how that could be caused by software, but it's a strange and murky world in there!
no updates installed of os.?
no new app recently installed?
Try andosensor and check battery level if its around the normal capacity when charging. Could be battery issue, could be a many things

I did update the OS, but that was a couple of months ago, long before this happened. I observed immediately after that update the battery usage seemed to get worse, but after a couple of discharge/recharge cycles, it got its act back together and has been fine since. That's why I was wondering about monitoring software getting out of whack this time - but couldn't see how software could make the case warm!
No new apps for at least a couple of weeks. I'll certainly have a look at Androsensor, thanks for the reply.
Your phone isn't going into deep sleep. Use an app called CPU spy to check this.
Mine usually recovers back into deep sleep after I reboot my phone.

Check for partial wakelocks. Otherwise, if you're complaining about battery percentage dropping when you reboot, that's because the battery monitor believes that the battery is not as charged as it really is due to high CPU load dropping the voltage.
Anyone else encountered this problem ?
I've had my Nexus 4 for 3 days now.
I turn my phone off every night. So two nights for this phone. Each time I have turned it off it has been fully charged, with the battery indicator and a third party app both showing 100 %. The next morning (about 8 hours later) I'm finding the battery has dropped to ~85%, so losing ~2% per hour when powered off.
Anyone else encountered this or know how to deal with it (before I contact Google)
Note - to power off I press the power stud until the Power Off menu appears, select Power Off, then click on OK to shut the phone down.
This is with Android 4.2.1
It takes power to turn the phone on. 15% might be a little much but it is not unlikely.

15% does sound a little high. OP, how's the battery life during daily/normal usage?

Battery life has actually been decent, I think I'm getting better usage than my old HTC Desire Z with extended battery. I'm not a heavy user, though I have been using it for music at work.

It takes a huge amount of battery power to start the phone from complete off, this also skews the first reading of the battery voltage as it will be lowered by the draw of power to start the phone so the indicator will read lower than it's true capacity.
The best solution is just put your phone in airplane mode at night, and turn airplane mode off in the morning, this is more power efficient than shutting the phone down using "power off", and you shouldn't see any battery drain apart from a percent or so doing this.
Regards
Phil
You can tell you guys never turn your phones off Starting up should have no battery drain - never been an issue on any of my previous phones and PDAs (last one also being Android).
I rang Google and they had never seen it before but recommended draining then fully charging the battery.
Friday night I made sur it was fully charged before unplugging and shutting down - next morning on turning on - 99% - result. Saturday/Sunday the same (note SAturday i fully drained then recharged the battery). This morning boots up with just 82%.
Looks like either it can't work out when it's fully charged, else there's some disharge mechanism in place to protect the battery and that's causing me issues.
It probably wasn't really at 100% even it was reporting as such. The reporting is broken. So when you rebooted you saw the real battery level.

I was just about to start a thread on this and then saw this thread here. So I'll ask here. I travel overseas a lot. So while I am on the plane I plug the phone in while off to charge it. I hit the power button occasionally to check the charge and when it shows "Full" I unplug it and throw it in my bag.
2 days later, I come back to the US and turn the phone on and the battery is usually below 50% even though it stated it was fully charged when I unplugged it.
So how does the battery drain if the phone is off?
I just sent my first Nexus 4 in for RMA on this very issue (if left for long enough it would just fully discharge), got the replacement on Friday, did a charge cycle, charged the phone fully up whilst off, took it off the charger (the official Nexus charger btw), and let it sit for the last day, just turned it on, and it's at 60%.... W T F !!!
This is sooo totally bizarre! I can only assume that this is common to most Nexus 4 (what are the odds of me getting two bad ones - direct from Google - with the exact the same issue?), and that people just aren't noticing, as most people don't leave their phones off after fully charging, and thus just never notice, as the battery behaves perfectly normally under usual use.
I would gratefully appreciate it if people could put this to the test, so I know whether or not to RMA the second device or not....

Are you using a custom rom, maybe its only sleeping.
Can't speak for the OP - but for me, no on both devices - totally stock. The latest one, box fresh on Friday! Also, the phone is most definitely OFF, and not just sleeping, ie, I press the power button & choose the "power off" option from the pop up. Unfortunately there's no way to really test this, by pulling the battery...

Nah - I tested it multiple times on my first phone. One time I left it for over two days and the battery went from "reporting 100%" to being under 10% whilst turned off!! Also on all the charges - I deliberately would leave the phone on the charger for multiple hours, even after it was reporting 100%, as I had the same suspicion. Often I'd leave it to charge overnight...
I have never had this issue with any other phone, or with my Nexus 7 (which I have subsequently tested in this respect, and it is perfectly capable of holding a charge whilst off)

It's not so much that it's a practical issue, it's more that I'm worried that it might indicative of a larger hardware based defect, and I'm not happy spending my hard earned cash on faulty goods.
If it's a very common complaint/fault then I won't bother to RMA the second one, but if I'm just ridiculously unlucky, and very few people are experiencing this totally weird behaviour, then I'll take my chances on a third...
Also, I don't think it's too much to ask to be able to turn my phone off to prevent it from losing any more charge. I can think of a plethora of scenarios where this would be extremely useful...
I'm now convinced of three things.
1. Android 4.2.1 can not properly read the battery state
2. Shutting down the phone does NOT do that, but rather puts it in to a hybernate mode that still requires battery charge
3. There is a fundamental design flaw in the phone that part causes this.
Most mornings I find my previously shut down at 100% charged phone at only 80-85%, though occasionally it is as high as 97-99, but not often.
Oh and my ROM is stock, my phone is not rooted.

I agree on all counts apart from the first, as my nexus 7 and my Mum's Nexus 10 behave totally normally in this respect, both on 4.2.1 and 4.2.2 (both stock/unrooted, although the Nexus 7 was rooted/bl-unlocked for a time).
Also, I don't believe it's a miss reading of the battery state, as I often leave the device charging for multiple hours after it reports 100%, by which point it simply must be fully charged. What's more - if you leave the device off for long enough it will fully discharge! The craziest thing is that the phone's battery seems to drain quicker when it's 'turned off", than when it's powered on and sleeping. Seriously WTF.
It must be something to do with either the LG hardware, or LG specific code in the Google ROM. Obviously the phone is incapable of properly shutting down, which is pretty crappy for a so called "flagship" device. As someone who likes to have full control of their device, I find it more than a wee bit irksome, that I don't have the ability to completely shutdown my phone! This is also where the irremovable battery is annoying, because there's no way to test whether it's a hardware or software issue, although I guess I could try a custom ROM and see if it still happens.... however I don't really wanna root & rom if I'm going to RMA it....
I'm really interested to know how many other people have this defect and don't even realise it, because their phone is either in use or charging! I find it hard to believe that I could be unlucky enough to have got two uniquely defective devices in a row...
I'd really appreciate it if people could check their devices for this issue, both on stock and custom ROMs, see if we can work out whether it's HW or SW related...

You could try powering it off with the bootloader. After you power off normally, hold power and volume down, when the bootloader menu comes on use volume keys to select power off and power button to confirm.
I'm hard pressed to believe the battery in my device would fully discharge if left off, when the phone arrived the battery wasn't dead, I got about three hours of solid tinkering before it died.

That's a good point. Mine came out of the box at about 80%.... hmmm. It could be that once it's first turned on it won't turn off again... this is such an odd issue! I shall try powering off from the bootloader next time, I'd still love to hear if other people's phones exhibit this anomaly though...
I'm aware that it's hard to believe issue, but there's only one way to find out...
I'm also very curious to know if loading a custom rom might solve it. I'm far less concerned if it's a software issue, I just don't want to have spend £250 on defective hardware.
I'm 100% stock, no Custom ROM nor kernal (kernel?) and my phone WILL discharge if left unplugged and "off". Happens every time I come back from overseas. Fully charge it up on the plane (even left the phone on but in airplane mode to 100% thinking that it was a misread of the battery level when the phone was "off") and still the same issue... turn it on a few days later and the charge is down to 75% or so....
I thought I was losing it... but I'm not the only one...

Ha - me too! With the first one, I actually went into a weird sort of denial, where I kept convincing myself that I must of got it wrong, it just seemed so absurd! Eventually I put it to the test (multiple times) and realized that my memory wasn't as bad as I'd been trying to persuade myself and the phone was in fact discharging when "off".
Anyone else?
Just got the update to 4.2.2 and have got my fingers firmly crossed that it's now a squished bug... although somehow I think it's more likely an LG/hardware issue...
What you could try to do it charge the battery to 100%, hold the power button for 10 seconds until it fully shuts itself off. Leave it overnight and see the battery level is at the next day.
