Hey< I'm experiencing the same problem on my TAB.

Exactly the same problem happened to me after upgrading firmware. Did u upgrade firmware or anything? How's your galaxy tab battery now? Still same symtomps so far?

i dont have this problem but my tab has a trouble charging the battery, when i plug it in for charging the battery percentage never moved until for about 6 hours then suddenly says fully charged but i take out charger it goes back to the previous percentage so i need to rebbot and after it shows the correct percentage kinda annoying.. this happened when i upgraded to roto-jmi v2may be i should downgrade to v1 coz i tried reflasing v2 still the same any help guys? callibrating doesnt work for me

Same thing here. Tried calibration, hard reset, flash new rom, delete batterybin file to recalibrate, still no go.
Returning is not an option since i got it from Negri a couple months ago.

Same issue here.
Just 10 minutes ago

here same problem too

Hi guys, try giving it a full charge every nite, e.g 11pm to 6pm, regardless of the battery level left on the indicator. I do it continously for full five days and I dun encounter this prob. Furthermore, my charge can hold longer even till 2 days full medium usage.

battery drop while turned off?

hey guys
i got a nexus 4 about 3-4 months ago. when 4.3 came out i let him update, so i'm running 4.3 stock. no root, no custom rom, no custom kernel.
for some time my battery acts strange, phone is charged to 100% then i turn it off for 2-3 days. when i turn it back on battery says ~ 50% so it seemsit dropped 50% in 2-3 days while turned off. already tryed different chargers and cables but didnt changed anything...
already tryed to find and answer on google and xda but i just found threads about poor battery life in general or some apps draining battery (when phone is turned on)
when phone is turned on its battery seems to be ok, compared to my old s2 it drains about ~ 2% / h while turned on and standby
did somebody got the same issue? and know how to fix it?
thx

If you are sure about this huge drop during off, you should send it back for service.
A device normally should lose almost nothing if its turned off.

[Q] NEXUS 4 Shutdown

Phone shuts down within minutes of taking off charge. Looses network every time before shutting down.
Doesn't boot up or boots and immediately shuts down. Battery charge shown in recovery and upon booting differ.
Battery calibration, safe mode does not help. Also disabled smart wifi settings, as suggested in many threads, to no avail.
Running stock 4.4.2, rooted, bootloader unlocked.
Works perfectly fine when plugged in.

How old is the battery, how many charging cycles did it have? Have you tried flashing the stock rom again (4.3 or 4.4)?
For instance, search for battery replacement on aliexpress.com.

The phone is around a year old. Battery stats show it's in good health.
I need to confirm it's a battery problem before replacing it. What about the signal dropping?

Update: Also flashed to stock 4.4. Still the same issue. In fact, the problem is persistent across multiple roms; AOKP, CM, PA, MIUI, stock...

It's most likely the battery, try to replace it with genuine one.

I too think so. Just looking for someone who's faced similar issues and what worked for them.

As you said, you bought it 3 days ago, wait until it sattles, maybe 10 or 15 cycles to start seeing good battery life.
I see 1% every 30 min not bad if 3g/4g and social media apps are running with push notification

Note 4 sudden battery drop

I bought a 1 year old note 4,it usually dies at 25% percent,it drops suddenly to 0 %.,after weeks of research i found it is caused by faulty battery so i bought a new battery now it dies at 10% to 0% in seconds and turns off,i flashed a kitkat rom now problem is solved but i want to be on lollipop due to UI changes,can any custom rom solves this? i've tried dr.ketan rom,same issue dies at 10%...

Probably caused by battery calibration. Just use your prior rom from 100% to when it shuts off a couple of times to retrain it.

If you use multiple batteries like I do, you'll never be able to calibrate, and will just have to live with this issue.

Well not entirely true. Ur battery have the chip that tells the system how much left the battery is. I often have those prob. But now is gone. I just charge until 100% let it 10min charged. Then use it until it off. (Really really off.) Like when the battery circuit stop the battery not the phone shutting down. After that charge until 100% and after 100% i let it charge for 1hour to make sure it really 100% . done

Same here after last update. From 10 to 0% in second

+1 here
Thats why I utterly I hate sw updates.
My Galaxy NOTE 4 SM-N910C

Same problem here ,, considering buying a new battery but afraid that the problem isn't from the battery and get the same drop again with the new on
my phone is 1 year old

i had the same problem, so what i did was to flash the Rulinglite ROM for my note 4 910 C. it works fine now.

Hey guys, I got the same problem. Sometimes it drops from 15% to 4% in a few minutes and then from 4% to 1% in another few minutes (without using phone ofc).
Also, when i charge my phone - it shows me 100%, but when i reboot it - i got like 94%. Few minutes later - again 100%. After reboot - 95%.. etc etc etc... (charger is pluged on for all this time)
Do you have this problem?

Same problem here

my problem is that the battery percents are getting lower ery fast..if i make some actions that require more battery and i have 20% of battery, the percent goes to 16 so quickly and then the phone hangs up. I turn it on, it shows lesss battery, then it hangs up again and i need do recharge the battery. I bounght the phone at 2nd hand, i noticed the battery issue since i was testing it, but i love the phone. i am affraid not to be a hardware problem with one of the internal components of the phone, that killed the battery...i tested the battery on Note 3 and i am sure that the battery has a problem. What if i buy a new battery and a malfunctioning component of the phone damages the new battery too?

For me: i will dial *#0228# press quick start and wait till phone lids up connect charger and charge until 100% and then dont unplug first leave it there for 30mins or more and then unplug. ( do not unplug it halfway )
Second i switch off my phone take out battery and wait around 3 mins and then put back in and start charging it to 100% without switching device on, also same thing leave for sometime before unplug when it reaches 100%. you can also switch on after 100% and wait for sometime. ( as booting phone drains battery too )
hope it helps

Bought a new battery still drains at 10percent exactly,thought it's a lollipop issue,but even in MM it exactly shuts off at 10%.
