hello guys,i recently bought a used o2 exec with 2 batteries(one extra old used battery) and pretty much disappointed with it,coz its almost like a dead one,its always turning off even when its fully charged,it stays for max 4-5 mins of work and tends to turnoff suddenly(the image is fading slowly and blackens up ending).then only remedy is to plugin charger in order to start it again.i had tried both batteries,but same problem occurs again.....now in the forum there are various methods for recaliberating battery.
1st) method says recalibration using bootloader mode drain method-it doesnt works as even in bootloader mode my exec turns off automatically even if battery % is much higher(60%,50% etc).
2nd)recalibration using plastic tape covering on one of the battery points in order to drain battery==same automatically turns off even when 70-80% battery left
now what i just want from you guys is a simple answer to my question-should i consider my exec as a brick & stop using it
or
take 1 more chance & buy a new battery.& try it on my device,i think this may not be a battery problem as battery calibration is also not workin,may be its a device hardware problem......
a batt can be defect and not being seen as such by % or fixed by calib
one of the biggests issues with laptops, phones and..... today imho is
that batts are crap
the % is never correct the usage is never linaer
and a defect batt can be seen as working ,,,,,
buy a real battery, they are more then the ebay ones but are worth every penny i have a bad batt right now as well i cant get more then 8ish hours sometimes less, but i bought from one of the better batt companies which was more money but lasted 2+ days and i will do so for my UNI i love this device

First off, I have seen many threads on the MDA PRO (and all its variants) cutting out at high battery power levels and from what I can see there doesn't seem to be any concrete resolution. But here is my situation.
I bought a new sealed MDA Pro and immedialy flasshed to the latest T-Mobile rom. Thats where the problems began. I seem to be plagued by the MDA cutoff at 60-70% problem.
The way it manifests is the radion loses signal and cannot locate the carrier at or below 70%. At this stage a reset of the device and it reboots but as soon as you use the phone or wifi it crashes .. black screen.
As with others if I connect the USB cable and charge by PC or mains everything returns to normal. Not a very mobile solution!!
I have tried every variant of ROM out there and the problem remains. I have charged the battery for 16 hours etc etc. I have tried phone in Auto, GSM modes .. same problem :!:
The only thing I haven't done yet is buy a new battery and hence my post.
Will the purchase of a new battery solve the problem? As with other threads it would seem this came along with the latest roms. Does flashing a ROM when the battery is less than fully charged cause problems?
On a final note, if after the radio loses signal it is turned off I have been able to run the device down to 20% running videos and MP3. Is this a probem with radio levels above1.09.00 (Just thinking out loud)
HELP: This device is perfect for my daily use and having purchased a less than mobile device I am now close to getting rid .. but I dont want to
Any advice greatly appreciated... expecially from those who have fixed the problem.
I had this problem and a new battery fixed it.
Thanks. Look slike a new battery
There seems to be different speculations on what causes the battery problem on the Universal: the power charge cable quality theory, one idea about the battery level stored inside the batter which some claimed to registry heck could change and another idea about the battery 500 charges limitations.
But if yours is brand new, then none of the above applies... So the refresh to a new Rom definately must have something to do with it. Wonder anybody who had bought a new replacement battery after the power drop had done another rom refresh and whether the same problem returns?
I have just bought a replacement battery (1800m Ah at standard size by MoMax which gives me another 30% more power everyday which is something good I got from paying for a new battery) yesterday to change the old one out for the same reason. Looks like until someone found the real cause, I am keeping the old one for my next rom refresh...
New Battery ... problem resolved.
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?

btw aj had the same prob. appeared after 6mnth. i bought new battery. btw here is several threads with same prob. try 2 look for solutions there(imho its only one-new batt.)
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.
After being dropped while charging, the battery of my Kaiser just use almost a day (previously from 2 to 3 days).
I installed acbPowerMeter to measure power consumption and it shows an unbelievable value: 4294967mA
When plugged into the charger, the power consumption back to normal (I think), between 90-275mA. I wonder if Kaiser power circuit is broken or not.
Who have experience please give me an advice. Thanks!
Hi, if you've dropped your device you should check the connections to the batery. Try pulling out the batery, check if the "pins" are aligned, check if you batery isn't cracked.
Other thing that might have happened is that if you install new software it may drain you batery, i had the same problem after flashing and was only solved after getting a fix from the chef.
Thank you for reply me!
I checked the battery connectors and tried different battery (borrowed from my friend), so the result is still the same. I did not install any software before and then.
Hello, I have same issue with battery drain. I don;t know if it was droped because I just bought it used and battery is draining in one day. I tried another tool called Mobadi, and it saying that my Kaiser using 90-200mA. how about you?
90 -200mA is normal draw. Your battery is losing capacity over years of use, thats normal.

...normal draw during screen on and active use...
with these older devices, there are too many tiny things that can go wrong which cause weirdness.
1. Testing with a known good battery (NEW does not equal 'known to be good'-- I had two new batteries which would not even take a charge, followed by a new NON OEM battery with a low capacity cell inside! they use some undersized cells probably for pricing reasons... sort of like sticking an AA battery in a C cell shell. Not really sure what you can do in that case...)
2. Hard reset and see if the problem persists before doing any more troubleshooting.
Hello guys i havae some problem with my Blackstone i use it from 2.5 years and i never had problem like this so..
Now when i recharging my device always stay on same % for example even for 1 hour its show always 20% or 50% or anything depends when i put it on the charger..
After restart can show 100% full or anything.. so i found out that the indicator absolutly do not work so if i restart it and show me the real % for example 50% the device always will show 50% battery untill the battery is fully discharged..
And right now i dont know how much Batterry i have and when will need to recharge..
I don`t know but i think this is a battery problem? i use this battery from the begining i mean from more than 2.5 years and maybe is time to change it?! but this heppand when i drop my device once on the floor so do thee is posible by droping the device some senzor to be broken or this is not posible i mean its a battery problem and i will need to buy new one?! or give me some idea how to test this and fix it.
Now no matter that the indicator do not work i still can use my device 1-2 days with one charge even if always show 20% this mean that in the battery itself have power for 2 days conversation internet and etc.. but just do not shown right.
Do anyone of you had the same problem ? and how do you fix it?
Also im looking to buy battery from ebay and i found today this :
http://cgi.ebay.co.uk/HTC-TOUCH-HD-...ultDomain_3&hash=item4aa9446824#ht_3230wt_905
What you think about this battery ? or can someone who already bought battery from ebay point me to get some good one
I read in the Diamond forum that peoples expirience the same problem with the indicator and even after Hard Reset or flashing new ROM the problem is still there.. so if this is right then i dont have reason to Flash again my device if the problem will be still here.
Any Suggestions?
Thanks
I did some tests... so i fully discharge the battery and i saw that even when the battery was on 0% and always the Warning appear i was able to play with the the Device with Wi Fi ON and Games and Music around 45 minutes wow.. this mean that the battery somehow was not calibratet and when its shows 0% in her still have around 30 40 % so after fully discharge the battery till the device Turn OFF by itself then few times turn it ON till there is not enought power even the WinMo to Startup i put it while OFF on the Charger and i was able to recharg to 100% and the light become green this mean the senzor itself work maybe just the battery need calibration again.
Now will see do the indicator work corectly after few more recharges and will write here for peoples who have the same problems in the future
...
hi dude, i think you should simply buy a new battery, but preferably an official htc battery - rather than the unofficial gold one you have posted a link to on ebay.
if you do decide to buy a new battery then put the new battery into your blackstone and charge while device is turned off.
this should fix your problem

Actually i think its not Battery die problem because i did some test and i see improvment my battery last at least 2-3 days with alot of usage wifi and etc so this is more than normal.. the problem was that the indicator do not work corectly and like i wrote above i discharge fully the battery till the device die and i saw that when my battery was on 0% i still play alot alot my device to swtich off this mean that befor when the indicator shows 0% its remain anorhter 30 40% power this heppand due to 2.5 years usage and i recharge the device when i have time not always when is fully without power and i think that this cause somehow a discalibration of the Li Ion so today when i did the trick i see improvments and now the indicator start to count ever single % so i think when i do this one or two more times the Battery will be calibratet and will show very corect how much Power i still have.
I think this way because if this battery was already died the device will not last 2-3 days with super usage.
It’s been a while that I have a strange problem with my batteries. I used two different batteries, both original, charged with the original charger support for the second battery (sell in bundle with it).
It’s almost two months that my phone started to turn off suddenly when the battery level is around the 30%, with both of them. I thought it was a problem related to the batteries age, since I’m using them in the last 2 years.
I tried anyway to contain the problem. As first option, I did a battery calibration. To do this I needed to discharge all the juice from batteries. I noticed that the residual 30% that I saw before the phone turn off wasn’t a fake value: it was real.
When I turn on the phone in recovery, the battery level is exactly the same that I have when phone turn off itself. Moreover, to reach 0% of battery level I have to wait a while and I can keep the screen on (always in recovery) for about an hour. On the other hand, if I try to restart the system, the phone turns off just after the Samsung logo of starts a non-sense bootloop.
Considering what I ‘ve written above, I think that my problem it’s not an hardware problem.
Does anyone have similar problems? Do you have any suggestion to avoid it?
As supplementary information, I’m running the last Italian official firmware with TWRP and root.
same problem
I am note 4 owner for 1 week now
it is an used phone (rebuy)
original rom 6.0.1 newest updates
on delivery the batterie was on 0%
first time use it shutdown at 35%
without warning
now after multiple charging and calibration
it shutdown at 20%
in 2 days I will get new Batterie and I will check again.
maybe batterie is old
Similar issue in the last week or so with my N4. Original replacement battery, 10 month old, turning off with no warning on reaching between 20-15 % charge mostly if i try to use the camera. I've put back the original battery and seems fine for now. Ordered another battery, Anker this time, just in case
Yeah Samsung carefully crafted these batteries so that they won't work any more after six months of usage of something. Mine is nine months old, the phone itself, brand new, and mine turns off at various battery percentages, sometimes its 5, sometimes its 12, I have stopped caring and I charge whenever I get a chance.
Conclusion Faulty Battery Only
Any battery poerventage is mainly determined with help of its volatage. As battery discharges this voltage also reduces. As battery grow older, we is gradually unable to handle the load as it used to when new one. Also battery life is determined by its charging and discharging cycles. It was all about basic. Now talking about note 4, being andriod fone and requres lot of battery so we usually charge it for 2 times depending on use.
The same problem was faced by me as well for note 4 at 30% it used to reboot all of sudden and thereafter bool loop (in actuality it is not as battery deoesnt handle load and it again starts to boot so no home screen). Replaced the battery with original one a month ago and now issue till date and fone lasts below 5 to 10% with 4G on and doing browsing.
So it is concluded for sure that battery problem.
Weird thing last night i experienced the same issue! And my phone is only 8 month old, i think this issue it's related to Samsung updates.. my phone did shut down in exactly 30% and started to go in bootloop i removed the battery and put it back and still the same i was about to factory reset my device for god sake ? luckily i did connect my charger before i factory reset my phone i gave it one last try and it did boot normally.
So i am not really sure what is going on.. no more updates for me unless it's a major changes

Happened to me too. I think it's the battery, I tried several batteries, some cause sudden power off some doesn't.
I'm upping my thread after two months to say that I solved my battery problem changing them. I bought a new one from Samsung official store and now I'm able to do more than 4 hours of SOT and charge phone once in two days (Red Dragon Note 7 porting). Before to change, I was not able to use any Sammy ROMs, due to several reboots and disgraceful battery life.
I don't know if the battery is the guilty for everyone's problems, but I really suggest to try to change it. Just, be sure to buy an original one, because there are a lot of genuine clones, especially on e-commerce sites.
For what regards the problem itself, I think that the cause could be the use of a different charger (Samsung, but for an earphone), coupled with the extra battery kit. Unfortunately the original adaptive fast charger stopped to work a month after the phone arrived and I didn't bother about it.
So, I also suggest to use only the original cables to charge the device.
I hope that this testimony will help someone with the same problem and, at same time, I also hope that Samsung will consider to use again removable batteries to give people the opportunity to do what I did.
