still running stock. battery dropped from 100% down to 0 with 1hr 27mins screen time. decided to turn it off and then try a charge. to my suprise was at 43%, i unplugged it and then now i am playing a movie on silent just to kill the rest of the battery, going to see if i can force a re-calibrate that way i intend to wipe it after.
i have emailed samsung support, lets see what they say, luckily i didnt break the 0x01 with the custom roms. i have my oneplus to play with custom roms, i use this purely as media consumption device, the 4g is handy too as i sim to eat. going off the subject now.
i hope to get more then 2 hours screen time once its all fixed. the wife is using the nexus9 i got her and when she picks up my tablet the battery just dies! shes getting over a day with her tab constantly on hayday! just 10mins of hayday earlier took the batt from 50 down to 11.
its got an issue for sure. i mean how would it charge from 0 to 43 in 2 seconds! haha
Its best for you to return it. Your supposed to get atleast 6-8 hours screen on time. You probably have a defective battery/connetor. All the best!
If you have a lower amp power adapter you
Could try to recharge with that ( 500 mah, 1000 mah) until 100%. Use your tablet until shuts down on her own, repeat the charging with this method 2 or 3 times. Maybe is not the connector is the battery calibration. I resolved my similar problem with this method ( i have now 4,5-6 hours of screen on time and no problems with battery %. Good luck

So it's already been established that after the EVO charges fully to 100% it then stops receiving a charge and runs off the battery before charge cycling again. All the while displaying 100%.
Has any effort been put into changing the way this operates? Seems like it'd be nice to leave the phone on a charger and when you take it off, it would actually be at 100% and not at some arbitrary percentage between 90% and 100%.
It's better for the battery life.It's really good option if you ask me.

You mean make it so that the battery's status bar shows a realistic value once it stops taking a charge, even though it's still plugged in, right? Not actually changing the way it takes a charge. I'd be interested in seeing that happen.
Is that why when you unplug it, the first 5% or so disappear within minutes?

Yup. This is why when you charge overnight the battery plummets right after.
*Currently Mobile*
Don't leave it plugged it after it reaches 100%. Problem solved.

Valid point. Lol
There are some people who don't want to wake up in the middle of the night to unplug their phone. Like me.
annoying, but just unplug your phone when you do wake and plug it back in after about 10 seconds. let it finish fully charging while you get ready.
it's better for the battery though, case closed. Lenovo has been doing somehting similar w/ their laptops for years. It never charges the battery past like 97%, and when it does reach the top it stops charging until it falls below like 92 then recharges. HTC needs to loook out for the battery they already have enough flak from all of us for the last few years w/ every touch device they have had. We want more life, and they are giving it to us, just wish they could figure something out like lenovo, let it go down to mayeb 94 then charge up again perhaps.
it really isn't true, mine dumps 10% or so off the charger regardless of if it has been on the charger all night or 2 seconds after it turns green.
So I've done the:
1 charge to green
2 unplug
3 turn off
4 charge while turned off.....to green again.
And here are my honest results.
Boom........phone has 20% left after 16.5 hrs of moderate use (calling time total 1 hrs talk total, surf /post 1 hour total, load up 5 apps from the market, listen to audio clips on the speaker phone for almost an hour straight, podcast this morning for 30 min...and other randomness)
And still have 20% left. Going since 6:30 a to 10:30 p...........approximately 16 hrs equals 80% so about 3.2 hrs left to use before dead.
THIS EQUALS APPROX 19.2 HOURS OF MODERATE USE BEFORE RECHARGE NEEDED.
eat it Apple 4G . You can't even reliablly make calls let alone last that long without charging. My 3g never lasted that long. You still need a wall Apple we are truly mobile. If I was on the road I could (don't need to just yet) swap out for another battery.
I'm loving xda for all their brains helping me get the most out of this phone. Thanks to all.

The point here is that we shouldn't have to do the "charger circle jerk" to have 100% battery. I should be able to unplug it and have a full battery. Not 90%. I might need that 10% later on today, its accomplishing nothing sitting on my nightstand.
If the battery is toast after a year instead of a year and half, i don't care. I want a fully battery, not an almost full battery.

HTC advised a similar solution to the battery issue. I did this a few times and my battery lasted more than 15 hours with moderate use. Here's the post:

My phone used to do this, even after i followed all the little tips and tricks of playing hide and go seek with the charging cable and my phone.
Know how i solved it?
Bought one of those $10 Ebay 2 1500mAh TP2 Battery And Wall Charger bundles, now i dont use the OEM charger at all, the cable turned into a permanent USB cable on my comp and never sees the actual HTC charging unit it plugs into for AC power. I have 3 batteries and i rotate them in that little wall charger which actually charges them to 100%. Its also proven because if you take one of the batteries, put them in the phone and charge them until the green light comes on, supposedly to "100%" and then take the actual battery out and put it in the ebay wall charger, it will still charge for another 15-25 minutes. Charging it in the phone, as soon as i unplug, it almost instantly always drops to 90%... charging with the ebay wall charger, it will stay at 100% for a while before it falls off.
Below is the link to my thread which contains linkage, pics and info about the ebay bundle, others also claim the same issues and fixes in my thread. I mean for $10 bucks, does it really matter if it works for you or not? Its worth the shot and for me, it was a great investment.
Best of luck.

I did this last night and I'm at 14 hrs and 57% left. If I have to charge like this to get great battery life that's fine. My iPhone 3gs would last half a day. So this is blowing it out of the water. And I can hold it with my left hand to talk.

Good stuff man, I finally just switched batteries after 21 hours.
Hello, a couple of months ago my battery started dying on me so I went to Samsung to get a replacement (my tablet is still within warranty). Despite the fact that my Knox counter is triggered they've changed my battery as well as my tablet's motherboard (don't know why). In the first few weeks I would get quite good battery 7-8 hours of Screen on Time, so far so good.
In the last month or so -though- I'm starting getting quite worse results. The battery leak while sleeping is 2% every 8 hours, so I'm great there too (amplify + greenify work miracles), so the only thing that I can think is that the battery has started dying again (already?). I've let my tablet reach 0% and shut down on its own. Then I booted into recovery and let my tablet on with full brightness for another hour until it was finally off. That's *one hour on* with full brightness!
It seems obvious to me that that's a calibration issue. I deep cycled my battery (twice!), but the results persist (battery is 0% after 5.30 hours of SoT, an additional hour of full brightness is needed until my battery is really depleted). I've made the calculations and found out that if I could actually use that extra hour of full brightness, I would still get 7-8 hours of SoT.
What happened? Why is my battery suddenly got itself "decalibrated" and why does deep cycling (or deleting the battery starts) never works? I think that I should get my tablet back to Samsung again (it's still within warranty), but I would prefer not to as it'll take another 2-3 weeks (again!) to fix it and I'd much prefer to have my tablet in the meantime. So do you have any quick and dirty method to get my 2 hours back?
BTW I know that 2 hours less of screen time , sounds little. But it's exactly the amount of time that deems whether I should charge my battery twice or once every day (yeah I use my tablet *that* much, as it also doubles as my laptop on the go)
My Note 4 is 14mo old and for the last couple months it just shuts off on me even though I have plenty of power left.
I am a light user and usually have enough power for all day use. I rarely use my phone down past 10-15%. I always put my phone on the charger when I go to bed at night when I have somewhere around 20% charge left. If I notice that I might not have enough power to get me through the day I'll put it on the charger somewhere between 30 and 40%.
Lately, like tonight I got a low battery warning at 30% power while I was on the phone. Not even two minutes later it shuts off. When I turn it back on it starts to boot up but then shuts off again. When I put it on the charger it was completely dead. This only happens 3 or 4 times a month but it's annoying because often it happens at the most inconvenient time.
I've also had it shut off and then when I put it on the charger it starts charging at 28% power.
Please let me know what may be going on here and a solution...
Thanks...

I had the exact same issue. I had 2 different batteries shutting off at 20-30%!.... Replacing the battery to a brand new one simply fixed it!.... if you are going to order one online try to avoid unknown brands . Also, pay attention there are some fake Samsung batteries claiming to be authentic.
Also if you still have warranty, contact Samsung and they should send you a new one. That's what i also did.
So you think its the battery and not software related? I was thinking software issue because I don't abuse my battery by running it dead and it's an intermittent problem.
I know that the life cycle of Li-ion is greatly reduced by repeated draining to below 10% (my kid's phones suffer from that. Seems like they can't make a battery last more than 6mo) but I've never had a phone battery go bad on any of MY phones including my old Note 2 even after two years. Maybe I just have a bad battery?

Doesn't matter whether you abuse the battery or not. Some batteries just go bad faster than others. I also think it's your battery.
A factory reset without restoring apps will rule out a software issue though, but since we can't root, it likely isn't anything messing with your battery percent unless it's just an app draining your battery. But even if it were the latter, your battery wouldn't die then start charging at 28%.

Pretty sure this is an actual built in feature. Mines always died at ~20% (since the 5.1.1 update) and once plugged into a charger and rebooted all my running apps and clipboard info is still running as if the phone never died.
My battery is brand new (from warranty replacement) and it still does this so this is why I think it's a "feature" to keep you from losing data in the event of a low battery event. Just my opinion.
It's not a feature. Mine goes all the way to 0% before it dies. I once read to take out the battery, hold the power button for 30 seconds (while the battery is out), then put it back in and see if it helps. This supposedly gets rid of any residual power storage. I don't know if this is a placebo affect by after I did that, my battery now goes all the way to 0 before dieing.

Not exactly a placebo, but not sure if it truly helps. Doing this would clear all electricity stored in any capacitors in the phone. I'm just not sure how this helps.
And my battery goes all the way down to 0% too. It's not normal for the phone to due at any other % (except maybe 1%).

hi, all i need to know is that this is normal, and ill forget it. i bought a hyperion battery and it kept rebooting my phone which i know like the zero lemon has been a problem. i was getting about 10 hours with that battery so i put back in the stock battery (2 months old) and it goes from 100 to 6 percent in six hours. That's with two phone calls five min each, no gps no Bluetooth no wifi and the screen at 50 percent and the time out at 15 seconds. i close programs all the time.. i have the battery doctor and all of that that tells me when programs are draining, but noting is helping. Is six hours what i should be getting from this battery with light use? i watch you tube videos of guys who get 25 hours but i know thats not the norm. thanks if any one has any feedback on this.

have you tried a factory reset? i know that has solved other peoples' battery problems
No, this is not normal at all. Either a misbehaving app or battery problems. You can try factory reset and see how much it drains with stock, or you can look for wake locks to see if it's an app before you try get ing a new battery
I'm on the Note 5 ROM and have a zero lemon battery. If I have cell on, I get about 7hrs. I can stretch that out to 10-ish if I keep going in and out of ultra-power save mode. The stock battery (of which I have 3) lasts me 2.5hrs. This is regardless of what ROM I have. Seems when I have cell turned on, the battery dies very quickly.
My Samsung Tab S 8.4 LTE (SM-T705) is 4 years old. Since the battery only lasted 2h 30m, I went to Samsung to change the battery.
But they refused to do so as they said, their diagnostic tools told them that the battery was fine, but the Motherboard needs to be changed. I believe there are 'some' truth to that as the Tab did had flickering, random booting happening a year ago (but did not occur anymore for some reason). But Mobo replacement is expensive, with a short warranty. Not worth it.
So I went to change the battery at another shop. The battery now lasts for 6 hours on Youtube (nonstop). Not that satisfied, but at least performs better (and also I can't remember how the original battery performs 4 years ago).
Problem:
1) When charging to 80% (Switched ON), the meter went from 81% to 100% in less than 5 minutes @[email protected] But when I unplugged and use it, the tab discharged at a normal rate (no sudden jump-drain).
2)Charging when the tab is off, it charged at a normal speed from 0% - 66. Then it gets slow as if it was 'trickling' and get stuck at 69%. Wait long enough and it will jump to 100% all of the sudden. Again, when using it, the discharged rate was normal.
So, does this mean the battery is faulty or just that the Motherboard is about to 'die' on me?
I would get the shop that did the replacement to fit another battery as there is definitely something wrong.

battery is at fault if it gets old enough , the flickering and rebooting is caused by a loose battery connector on the motherboard. soldering and strengthening it fixed the problem for most people i found posted on their forums ,
i personally haven't tried it yet as i just replaced my battery after the original one died this 2021, replacement battery is 6 months in and the problem i'm having with the flickering is coming back.
