GT-N7105T - First Full Charge

Hi Guys,
I just wanted to throw something out there...
Just got my shiny new Note 2, and its rad. But, just wanted a second opinion.
I'm aware that generally a Li-ion battery needs to be "conditioned" but usually you get a "fair" idea of battery life within a day or two. Now, had it for a day, on the day I got it, tried my multimedia dock for like 15 minutes...freaked out because I forgot it charges it too. Took it off...flattened the phone till it turned off and charged it, while off for 8 hours over night.
First day has been fairly standard really...much the same as my Galaxy Nexus. Currently on 2 hrs screen time, 36 mins of calls and I'm already down to 45%???
Is this "normal"??
I'm just a little concerned that I may have a crappy battery. I feel a bit "to soon to judge" so I might see after a week. Just wanted to know if everyone else had the same sort of experience.
Thanks in advance.

AFAIK the battery needs a few charging cycles to get it's full capacity. So it will become better.
Have you set the slider for auto brightness to minimum?
That made the greatest power boost for my Note 2.
If the slider isn't at minimum, your values look normal to me.
If it is, you should have more battery left. But here I have to refer to my first sentence.

Drained 55% in 2 hours of screen time and 36 minutes seems weird but it's too soon to judge. Get it down to 1% and fully charge your battery to the max with your phone off and see if it works wonder the next day. Do let us know the outcome.

Thanks guys. I definitely will.
I just thought me fully draining it yesterday would have made today pretty good. Your right though... I feel I'm judging a little too quickly. I just thought I'd get a surprise straight away with this phone as I know it's got unreal battery life.
What were your first days like?
Edit - My screen has been on auto all day too... Hrmmm, starting to worry... Haha. Luckily I haven't rooted yet.

Even if it is on auto, you can calibrate the brightness with the slider in the notifications.
For me it's bright enough if it is at min. And it saves you loads of battery.

Update.
Did a full charge from 10% last night... While on though, does that make a huge difference?
Did this code today *#0028# and like a battery stats reset tool comes up. After hitting quick restart it's drained allot slower. Maybe it didn't have that done out of the factory. Still feel I have a crappy battery though... It's only been 2 charges. Going to do 1% then charge off tonight. See how we go...
Anyone know what the code tool is actually for?
Cheers.

I got a 4 day juice after charging it for the first time with screen on for 4+ hours. Still getting the same or better at times. One thing i have noticed is that leaving the phone connected to the charger for another 20 mins or so even when its fully charged gives it a push in the right direction. U can try that out if u want.
Following are my 1st charge stats

Galaxy S3 AT&T Battery Going Crazy

Hey all,
Let the following speak for itself:

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
This started happening out of nowhere, a couple months back. My phone will lose battery at an incredibly fast rate, then swoop back up (without being plugged in), then fall, etc etc until it hits 0%. I can then turn it back on and it says 50% or what have you, and the same process repeats. These are the things I've tried:
1. Bought a new ZeroLemon battery because I thought my battery might be broken. All this served to do was increase the number of swoops. The battery still barely lasts half a day.
2. Cleaned the contacts of the battery and on the phone.
3. Installed all kinds of battery helpers and battery recalibration apps. Here's a screenshot of an app telling me, after I charged the phone to 100% (with a separate battery charger so I know it was at 100%).
It appears the phone is just reading the battery incorrectly. Not only does it report 60% but it also reports 3800 mV, which a fully charged battery should be around 4200 or 4300 correct?
4. Now here's the weird one: I blew on the contacts. This made things work better for a week or two. The new battery lasted about 3 days, which I thought was pretty good. Now it's back to where it was again.
It seems like I've tried just about everything, and it's a problem with the phone. Only problem is, as you can see, I have CM installed and the phone is over a year old, so any kind of warranty is long bye bye. Any suggestions my fellow S3 owners? I've tried googling this problem everywhere and it seems I'm the only one with it.
Thanks so much

I'm not sure exactly how to fix your problem, but just wanted to state that battery helping apps and calibration apps are bogus, they serve no purpose!

I also forgot to mention that I have tried formatting everything and installing a different ROM etc etc. Is there any option short of buying a new phone?

[Q] Very strange battery behavior.

Hi all... first post, first problem with android... and hopefully a long time here in xda!
So I have the T320 (8.4 pro) and I have a strange problem with my battery. Is not only that it lasts no more than 4 hours (screen), the problem come by low and high battery %.

By low, the table shuts down and after starting it again, it shows between 5 and 10% battery!!
Something similar happens by charging... it shows 90% and no change... and after a reboot it shows 100%.
Is my battery dying? Should I wipe and restart from zero? Cyanogen?
The speed how fast battery drains is also extreme compared to stand-by times... but I assume this is more or less a problem of this tablet.
Many thanks in advance!

Having similar issues. Found mine dead out of nowhere one day. Never had custom ROM on it. Did factory reset now it seems like it doesn't want to charge .... Charges VERY slowly if at all.
Sent from my SM-G900T using XDA Free mobile app

i have the same issue, dropped from 50 to 15 all of a sudden , will try calibration , anyone else noticed this ?i picked up mine used so unsure whats the issue

i found better battery life after i did a factory reset. i bought it new and set it up and since then had 1 Sammy update but last week i reset it and it clearly made a difference on my 10.1. yesterday i had 2 hours screen time and on battery for 2 day and some hours and had 60% left.

Add mine to the list....seems to be doing the same thing here. Haven't been able to sort it out yet.

Took the back off mine tonight and reseated the battery connector. Then charged like below. First to time in a while it charged up like this.

can you post a pic of videos of how to pry it open ? hopefully simple with a prying tool

I just very carefully went around it with one of those guitar like plastic openers i have laying around from the many tablet/phone repair kits i have used. I probably rebooted it 5 times before i finally popped it apart... thing just did not want to charge. This was the first time i saw it ramp up 1% at a time in a while. The other thing i noticed it was doing was jumping from ~70% to 100% instantly.... The graph showed it too. I didn't believe that was really happening.

some pics would help , is it between the screen and the metallic part or the back and the metallic part ?

Opened mine up because of the battery charging stalls and reseated my battery. I bought this tab 2 weeks ago used and this is the first time it has charged to 100 without me forcing it too! Its def worth doing if ur battery stalls!!

Mine has been really good now for days too...any hint of battery probs are gone!
I suspect an app did this too. I was on cm when it started...others were stock. Chrome or some other common Google app put our tabs in a funky state.

Battery drain???

Is there a drain??

May I ask why you suspect a drain, like how long does it last and also what's wrong with the built-in bat-stat?
My biggest recommendation is to avoid DL'n every single app and keep it to a minimum.
Mine last roughly 2days with a screen time of 3-4h without charging (was away a weekend recently and took my chances and left the charger at home, used the camera alot incl. 4k shooting and alot of music videos playing and made all the way home with 1 percent )
Best phone in terms of battery I've come across yet.

on the stock rom and kernel?

Hello, what's your android version and firmware build number? I would like to use it because i'm on 4.4.4 build 14.4.A.0.108 and I'm experiencing fast battery drain.

Changing ROM will not help in most cases if you won't discover what is eating battery.
I am on the same above ROM and kernel and I don't complain.
Term 'fast' is not much precise, either.
BTW:
1.3%/h is pretty reasonable if phone was in use from time to time.
Base rule with BBS is to check batery over night, when it is not used at all.
Under those circumstances you should see 0.1-03%/h and that is completely fine.

As always - check that all automatic synchronizations are off.
google, pictures, facebook, whatsapp.
Hope you don't use WiFi all the time, nor you scan for available networks.
BetterBatteryStats is really helpful, read corresponging thread.

i dont think using wifi and auto sync will drain my battery from 60% to 6% in just a second. Anyway, i ordered a replacement battery from witrigs. Hope this fixes my problem. Ive tried factory resets and repair through pc companion. still no improvement. Turning stamina mode improves my battery. It no longer drops 50% in a second, just 10%. Still way too low compared to my excellent battery life with kitkat. Before lollipop, i charge my phone every 2 days with heavy use. Now, i need to charge it twice a day with moderate use.

If so - I'd come back to KK before replacing battery, if for no other reason then to prove LP is guilty.
BTW:
Long ago I decided not to upgrade to LP.
Looks like evey step ahead is in real life step back.
Everything is more complicated, wants more maintenance, yet works worse than old simple tools.

LG G3 BootLoop

Hello everyone .. i know you've faced alot of topics with the same name but somehow i find mine different ..
Months ago when i use the phone much it gets laggy then it shuts down .. i thought it was normal due to overheating issues
then month ago it went totally off .. not turning on back as i used to .. so i searched online i came with 2 solutions :
1)might be software related
2)BATTERY
so i went to a repairing shop and he flashed a stock marshmallow .. then the phone worked for 1/2 day then it stucked at bootloop again
so i went back and changed the battery .. that worked for 2 days but it was draining fast so i replaced another which lasted 1/2 day before going bootloop again ..so i refund.. i searched again and found the paper trick and copper wire trick and the paper didn't work for me .. but i go from the wire topic that he measured the voltage of the battery and noticed it wasn't 3.8v so i went to measure mine (the one which came with the phone) and it was fine .
so if anyone knows how to get over this please help me.
Thanks

Was your battery officially made by LG? Is it the same model?
When you bought the new battery.. Did you first empty it (0% exactly) And then recharge it to 100% and leave it closed for about 10-15 minutes?
If the battery is officially made by LG and has the same Model name on it,then have you ever dropped the phone?
Greetings.

I think it's because the batteries that you have are made in 2014.
The new battery that i recently received is made in 2016 and i don't have any problems at all.
Maybe 2014 batteries have that bootlooping problem.
