Battery can not be fully charged - 8.4

I left my 8.4 charged with the wall charger over night, in the morning I found it's only 94% full, this happened multiple times, and I also tried another wall charger it still happened. The battery chart shows it stopped at 94% (some times 95%) and never went up. Does anybody has the same problem? Is there anything wrong with the battery? BTW, the battery life is not good for me, screen on for only 5-6 hrs on about 30% brightness.

stock rom, not rooted. I doubt it's caused by any app, if in that case the battery should still be fully charged then go down, but it's not what I saw.

Yes that's exactly the same as mine. I contacted Samsung support and they suggested to do a factory reset to see if it's a problem about software, otherwise I'll need to file a service request.

This happens all the time. If I reboot the tab will then show 100%.

Let it run down to 10% then recharge. do this a couple cycles. You could also try a battery calibration app that wipes the stats and starts fresh.
Solved my issue a while back.

A restart used to fix my issue but now the tab will say it's 100% charged and then at some point drop 10 or even 40% randomly.
Something is definitely wrong with the battery on this thing.

it's not the battery, but the reporting statistics used that is bugging out.

Is there any way to fix this? If it's fully charged then it should show 100%.

I have the same issue, read here:

I found the problem has become worse and worse, sometimes it just stopped at 30~40%, then I said "f*** it", opened the back cover, pulled the battery out and put it back, reboot. Left it charged during the night. The next morning I found it charged to 100% !! Will post back if it really solved the issue after some more cycles.

I simply let the battery drain to around 20% and then charged it fully. Ever since (1.5 months ago), it has been reporting accurate battery %.

But the problem was the battery could not be charged to 100%, even if I left it charged over night, in the morning it showed 30%.

Mine works 100% perfect on ND3..
I have tried to make it do somthing weird..
I can't see anything in the ROM coding so far that would cause this..

So over a week later and my battery has been perfect.. Stock rooted nai....
4hrs 40 mins of screen on too..

Hi. I dont know if anyone is still on this post but i have this device and ive had this problem for the last year. It would get so bad with all the discharges that my battery died. I bought another battery and replaced it. I still got -300ma when connected to a 1A chaarger. So i replaced the flexi usb port membrane in hopes that would do it but i only got to 100mA. I bought a 2.4A charger and the tab doesnt even recognize the charger is in. Cant really turn it for service because I rooted it so my warranty is void. Any commentary and opinion would be greatly appreciated.:good:

Solved: Is this normal??

Two days ago.. bt this issue is there

The battery meter is just an estimation of battery life. It shouldn't be expected to be that accurate (within a few or even 5 or 10%), nor should you make a habit of draining your phone to below 10% anyway.

thanks for your reply but i managed to solve my problem ... i wiped cache partition and performed soft reset for two minutes.. and now battery indicator is fine enough and i m getting 4.5 hours screen time with 35% brightness and locations are completely turned off. (Fck you google) and standy by time is much improved as well.... 1% battery drain in 2.5 hours on standby...... i m one stock lollipop .. unrooted as well... quite satisfied. now... i m happy to go for htc and not samsung because they have drastic problemss with lollipop

Battery Loss

I have noticed in the past 3 weeks that my phone rapidly discharges. I have done a factory reset, uninstalled programs that i really don't need, and moved a lot of apps to SD card and i am still losing power faster than i was in say April or even July this year.
Anyone else experiencing this? Not rooted BTW.

Like how fast does it discharge?

Lets say I plug it out at 9am. by 12 midday it has already lost 3-5% or even more. Overnight like 10%. it used to only lose 3-5% overnight.

Okay so I can tell that the initial drop is a bit unusual because even on my S8+ when I unplug the phone from around 8:30 A.M (100%) it drops 1% around 10:00 A.M. or 10:30 A.M (This is with AOD on) and the overnight drain also seems unusual cause for me I face like a 5 - 6% drains due to my social media apps always retrieving notifications.
But try giving this app a try and see:- Servicely It may help you save up some battery. But before you try this app I suggest Like Re-calibrating your battery, the best way to do this would be to fully charge the battery and then drain the battery till it automatically switches off, repeat this 2 - 3 times and then give the app a try

Thank you for the advice. Funny enough, this week I have been making it go all the way down to 6% or so before I recharge it. Also, screen broke in July so this phone is literally 2 months old as I got it July 5th as a replacement. Brand new and in the beginning I was so impressed with the battery usage. Since then, it has fallen off dramatically! I keep hoping an update will change it but not yet, the last one last week for facial recognition, etc did nothing for the battery.
I will try and recalibrate it over the weekend/next week.
Thanks.

No pb, before having an S8+ I had a OnePlus 2 and I was having some battery issues, so the normal battery calibration helped solve the problem for a few months until I bought a new battery for it. And we'll have to hope that Oreo would optimize the battery life

Do you have to turn your phone back on as soon as you plug it in or keep it off? Would it matter either way?

theres battery/power adjustments options in the phone... touch the battery icon

Update: Since I posted this, it was determined by Verizon that the unit was to be changed out. I got the new unit and so far(fingers crossed) I am getting about 2 days out of 1 charge. I liked the suggestion about recalibrating the battery. I am now losing 3-4% overnight when the unit does "sleep". Much better than the 10+% it was losing before. Not sure what was killing it but thanks to all the suggestions out there. I will see if there is any improvement when we get Oreo update.

Is the battery life normal or is this a serious problem?

I've a brand new Xiaomi Mi 10T Lite, but since a few days I notice that it seems that the battery is draining fast.
So I've done a test: I've charged my phone to 100% and used it until it turned off due to too low battery and it lasted 23 hours and 3 minutes.
But I doubt if this is normal and I'm kinda worried about it.
I've bluetooth off, and wifi is always on except when I go outside and then I use mobile data.
I use my phone for surfing, using social media, chatting, gaming, making nice pics and more.
So is the battery life normal or is this a serious problem?

is 23hr bad ? I feel like my one is always above 80% as it charges that fast I don't seem to notice the battery being low

I dunno

I haven't mentioned the standby time and the active time in the topic, and I cannot find that data anymore so that means I have to do the test again

I would advise to install AccuBattery app, fully charge the phone and look at screen off and screen on power consumption at the end of the day.
These numbers are "normal":
Screen off - no activity (over night or phone just laying down for a few hours): 0.2-0.3%/h
Screen off - the usual daily activity (moving around with the phone in the pocket, Whatsapp for web active, Google location tracking active etc.): up to 1.3%/h
Screen on - about 7-9%/h

I'll do another test on Friday as I said.
I'll charge the phone to 100% and use it until the phone turns itself off due to low battery and look at the active time then.
I'll post the results here if the test is done.

What were the results?

Today I've redone the test.
I charged my phone to 100% and I then I used it until it was 5%.
I got an active time of 5 hours and 27 minutes and the standby time is 18 hours and 1 minute

My phone is pretty new and I am using it more frequently these days. This leads to similar battery times like you describe them.
I did not do the exact same discharging like you did, but imo battery drains mainly during screen-on time. Over night it is quite stable and only slowly discharging.
Maybe power consumption is dominated by the LED screen? This might be the reason why Xiaomi has such an aggressive screen dimming implemented...
I think what _mysiak_ is describing above, is pretty accurate and explains what you are observing.

Unless your trying to calibrate the battery that's really stressful to the battery to use it like that.
Puts a lot of wear on it... fast.

I know that, and I used to do that all the time but when I received my new phone I changed my habits.
I'm now trying to keep my battery level between 90% and 40% or 30%.

Question Will OnePlus 9 pro battery life be improved with a software update?

Im planning to buy OnePlus 9 pro phone, everything in this phone is perfect for my needs except the battery life. almost all the reviews on the internet suggest that the battery life of the phone is average, and some site say it's worse than that of the oneplus 8 pro, even though both phones have roughly the same battery capacity with the oneplus 9 pro having more efficient display and processor. so do you think it will be improved soon with a software update? and for those how bought the oneplus 8 pro at lunch last year, did you experience the same issue?​

It charges to 100% in under 30min...
So seriously, what is it that you do all day where you need to have your screen on for 6-7h, hard usage, without any acces to a power plug to charge it?
Are you a ranger in a Safari Park that tracks Rhino's?

Battery life isn't great, but I top it off for about 10-15 minutes late afternoon (half a charge or so) and I'm good to go. I'll keep my old 30W charger (from my 7 Pro) in my car just in case I'm ever caught with a low battery, but it doesn't seem to be an issue. I certainly welcome any improvements, though.

Usually, ota updates have battery performance improvements...

In the summer i will be moving back home where frequent blackouts are a common thing specially during the hot days, that is why im worried about battery life. and i dont like carrying power banks.
Anyway thanks guys for the replys, and hope future updates would include battery improvements.

I've upgraded from a Samsung Galaxy Note 9. I'm really surprised how quickly my phone has died the past few days at work. Only gets me through about 8hr of listening to podcasts, screen off before I hit 20%. I hope that something improves because I was hoping with this phone I'd be able to get through more of my day without charging.
It's astonishing to me that all the improvements to hardware and particularly power efficiency over the years have resulted in... the same SOT and battery life in general as my four old phone. Progress

They'd rather have the phone charge from 0 to 100% in about 30 minutes so that's their *solution* to the "problem".

Idle or standby battery drain is too much.. Anyone facing that? How to reduce it. My phone was charged 90% in the night. After 9 hrs standby, battery went to 67%. Thats too much battery drain

Mine drains about 5-6 % in 9 h standby. Always-on disabled. Try disabling "listen to hey google all the time", that might be the culprit.

As someone else stated earlier, my battery was horrible when I first got it for a couple of days, then without doing anything, it just got better, like a normal phone. No complaints now. That was my only gripe.

Btw a new update that ends .3.3 seems to be rolling out in India and should further improve battery life. it's great to see they're doing something, hope battery life will get even better.

Yeah I now have my phone for 2 days, it's a garbage battery!
It drains like close to 20% per hour of 'light usage', with low brightness only FHD......
Also it drains the battery even when it's supposed to be Idle (no AOD)!
Will probably return this ****.
