Universal==worst Made,now New Problem

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

Momax X-Level battery damaged?

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`?

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)
-Valynor

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!!!!!!?

[Q] [Help] My battery is draining too fast, some soft problem ?

I bought this Hero off eBay, and it was dodgy since the begining.
The phone had cyanogen, and was restarting itself occasionally.
So i wiped it, installed 2.1 and it got fixed, but now i have a problem with battery drainage.
Its insance, 10minutes-10% im pretty sure its not supposed to be like that. with or without wifi/3d turned on, its just riddiculous.
I borrowed battery from a friend, and that didint make any change, i installed latest update from the autoupdate in the phone and still its bad. I read somewhere here that its faulty email app that keeps on trying to sync and drains battery, how do i fix that ?
I did a full wipe, cleared cache and everything back to factory settings, with no apps installed it goes from 100% to 0% in an hour.
I downloaded 2.1 from some android forum, as i was unable to find one here (there are only links to 1.5 on the xda.wiki WHY?)
If you can point me to a proper 2.1 (or higher?) software to download that doesnt do this crazy **** i'll be happy as infant on crack.
Please help, here is my software information:
Firmware: 2.1-update1
Baseband version: 63.18.55.06JU_6.35.09.26
Kernel version: 2.6.29-063c4d24
Build number: 3.32.405.2 CL191507release-keys
Software number: 3.32.405
Browser version: WebKit 3.1

Try calibrating your battery it gave me a huge boost on my hero... went from getting 16hours day.. to about 30hours on a single charge!!
Every time you flash a new ROM you need to calibrate your battery. The battery meter in the OS (Android in this case) is generated based on the battery stats file.
Battery stats is erased when you flash a new ROM.
Easiest method of battery calibration when you're intending on flashing a ROM:
Ensure battery is fully charged according to the OS. Switch phone off, unplug charger and plug back in. Once light is green, leave charging for another 30 minutes (light goes green at approx 95% charge).
Switch on, flash ROM. Allow first boot to complete.
Shut phone off. Disconnect charger. Remove battery. Replace battery. Place on charge, light green, leave charging another 30 minutes, yadda yadda. Switch phone on, boot immediately to recovery. Wipe battery stats.
Boot phone up. Now would be a good time to install JuicePlotter. Use as normal. Do not charge, let the battery run down completely. When the phone shuts itself off, power it back on. Repeat process until it won't switch on anymore.
Remove the battery. Put the battery back. Turn the phone on. Repeat until it won't turn on anymore.
Now charge the battery on the mains to 100% while the phone is off, keep charging for 30 minutes after light goes green. Power on. Voila, fully calibrated battery.
The last part, run until completely dead and charge only needs to be done once in a while (this is calibrating the battery innards, not the battery stats)

hah, yea thats what i accidentally figured. phone was switching off, but when i powered it back on it had 30%.. and it was like that 3 or 4 times.
I ran it down completely and now am charging it till max, we'll see what happens. at worst i'lkl start your process from the beginning thx !
I diidnt know you had to do that. i've been playing with my G1 and not even once i had to calibrate that.. maybe i should

How'd it go? Any improvement on battery life?

it diidnt help I did what you quoted step by step and its still running down the battery like crazy :/ what else can i do ? im thinking of switching to 1.5 but thats just not progressive and my friends phone is running fine on 2.1, with the same battery even.
Edit: i've installed task killer and killed all the mail checking apps.. hope that is the problem
Edit2: it didint help at all, in 5 minutes i lost 15% fcuking hell !

I just switched to 1.5 and its still happening ! I using a different battery and its just as bad... why is this happening to me
ill try second to latest radio from xda wiki.. im running out of ideas,what else can i do ?

That really wierd... its not the battery if you have tried using different ones. Its not the ROM if u have changed it.
Have you tried disabling auto-updates? and auto-checks for emails. Which email client do you have? you should find the option to "sync-never" in the app settings.
Buying it from ebay is kinda ominous though.. was it described as faulty? perhaps you could contact the seller and request a refund is all else fails?

you can try using setcpu to underclock the cpu.
i have similar situation as you. before going to bed around 11pm, it showed 50% left, turned on airplane mode, then in the morning around 6am, phone was powered off.
now it has been 2 days, still have 20% left.

Did you ever take into consideration that some part of the hardware might be damaged?
Devices that got water damaged, sometimes show weird symptoms as well:
- They still boot up and seem to work well from the first sight
- The battery drains very quickly
- Some of the peripherals are not working stable or not starting up anymore (e.g. wifi, bt, gps)
- Other crazy things might happen as well (e.g. random reboots, backlight flicker, etc.)
So you might have a look at the mainboard. Red stickers indicate water damage!

Yea but if it were damaged would it show 50% battery after restarting thinking it had reached 5% ? i dont have the tools or will to unscrew it.
i paid 100 pounds fo it, the normal price of a used hero, but the auction said "phone restarts for no reason" and they do not accept returns, so im propably screwed :I

I had an old blackberry 8300 curve, i had it in the bathroom while i was showering, got too moist, turned the detection pads red but phone seemed to work fine after i dried it out. But the battery went to crap progressively in the manner. I would charge to 100%, take it off the charger and maybe an hour it would say less than 10%, do a battery pull and it would go back up to maybe 80% and last maybr another hour and keep doing that till it would normally drain on top od the numerous reboots i would be doing until eventually it would just drain and die.

Can dead pixels cause this ? i have like three.. but then again why would it show 50% after restarting from 5%..
the thing is its not draining the battery, just registering it wrong

Any updates on this? Any resolution?

sorry mate i have tried everything unsuccessfully and returned the phone to the seller.. dont tell me you bought it ? (london)

No, but i have a samsung galaxy tab and experience similar symtoms. It does not bother me too much, the battery life is still great. Just the percentage is off and i need to restart from time to time.
I read similar complaint from droid x forum too.

Battery problems

Hi,
I konw there are so many of these threads but I've problem with a brand new battery..
I've a brand new battery and have calibrated properly after flashed ddjp6 with fugumod ultra...
Now when I play a game or use internet, it suddenly shut down (the phone) within 5 minutes even at 91% battery.
And when I started phone I put on charging, it copleted in 15 to 20 minutes...
Again use , again shut down...
Any one can help..
Thanks in advance...

Is it an original battery?

Ya
It's from samsung store...

Mine is also new nd facing same problem...
Sent from my GT-I5800 using XDA App

Is this a problem with some app?
Because phone shuts down before 0 battery...

I had this problem but it was solved after buying a new battery. Your new battery may be defective...? I don't know, try your friend's battery or something first.

Calibrate your battery using battery calibration app.. You can download it from market for free

I've tried it.
So I came to know that battery was 90% before starting internet,
Then shut down after a few minutes...
When I started the phone , it was 40%...
So before battery goes zero,
Phone, shut down...

Ive done it...
Battery 90%
Started internet
Phone shut down within a few minutes
Started the phone
Battery was 40%
That meabs before battery goes zero,
Phone shuts down
:what:

Is your problem solved?
Tell me if you get any soln...

I have the same problem! My battery is 1 year old. I changed few ROMs and Kernels, wiped batterystats... nothing helped!
I'm using internet for 5min. (100%->89% sometimes 70%) and than it shut down immediately.
connect it on charger (90%)
after 5-10min. charging, battery is 100%
without using it lasts for 3-5 hours.
Now I'm waiting for a new battery to come, and after I test it I will give a report.

Go to customer care...
I just have solved my problem...
If you can't find any other way...

so what did they tell you? you got a new battery? is it a problem in hardware or software?

I went to customer care and they are saying that its hardware problem
To nidjo 16
If your problem not get solved after a new battery, go for store,
Because we already have tried kernel and rom options...
My problem now get solved
Hope your problem get solved...

Well they told me that it was some hardware problem...
Though they didn't tell me about the problem exactly,
My phone is working good and that is what I need

I'm having the same problem.
Have anyone tried replacing the battery?

If the battery is even slight bend,
Replace it

Rude customer service by samsung
Samsung service centre in RK Mutt rd, Chennai is very very Hostile to customer.
I was treated worst by the 4 jokers at the counter
everyone acting busy and thats what prompted me to find this wonderful forum..
The battery problem can be solved as follows:
1. Discharge battery by games or any high battery consuming apps
2. Charge the phone overnight [it may take 5-10 full discharge cycles for battery to understand and give a good backup!!
3. delete Battery stats using CWM
Try an alternate kernel..

Some modifications I got with my customer care (which is very good! )
For 1
Charge after battery goes below 20 at least once a month...
For 2
Don't charge over night, when the battery is new...
At least for the first time
More stuff
Do not use much during charging...
At least internet or wifi
And don't charge for too much time...
(i mean when battery level is still high for use)
Cheers....

Had same problem
used a new Rom and new Kernel and tried so much.
Battery Calibration dont helped.
then i changed battery and yeah that helped since the new battery all is working well
But yeah if it helps I must say that i charged my phone most time via usb and used it for internet via usb teethering, now i only charge it over night and the battery stays much longer
When only use it for music and use internet only shot or use wlan then it stays for 3 or more Days and i think that is very good for an android phone !

[Q] Battery problem - suddenly turn off

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.
