Very bad experience... - Galaxy Tab S General

One week ago I bought new galaxy tab s 8.4 lte version.
Box opened, turned on tablet and...strange thing...battery was down to 4%...generally a new device has more residual power...
Anyway, i charged it all night for ten hrs.
Turned on again and 100% charge.
Everything runned ok for almost two days...then my tablet started to reboot randomly under 50% charge without no reason. No overheat, no strange app, no cpu stress. Just browsing internet, using facebook, sliding app drawer.
When it rebooted again charge was at 12%. Rebooted again...charge at 62...then 32%...and so on...
Maybe a battery calibration issue. So I decided to restore to default settings. Did it for 3 times...same behaviour...under 50-40% tablet started to reboot randomly.
Rapidly returned back to the store and changed with another one.
No problems at the moment, battery drain is regular with no "jumps".
Maybe it was just a defective battery but it was a very unpleasant experience.
Hope this is just an isolated event.

Well It doesn't sound normal for this Tablet .hope you get a better taste with your newly exchanged Tab.

Not sure which store sold you the tablet, but a "new" device would not be down to 4% on the battery on initial start-up.
Makes you wonder if the tablet was previously returned as defective and the store sold it to you anyways. Hopefully that wasn't the case.
Here's hoping your replacement tablet will work as advertised!

All the samsung original seals on the box were intact so I think that it was simply a defective battery.
The new tablet was at 45% charge when unboxed.
Fortunately no strange reboot for now...[emoji6]

there are a case here when some user having nearly the same problem. and he's kind of open the back cover himself to discover that the battery connector are not seal properly. yours might be in the same case.

That has battery connection problem. Maybe u got the 'QC Failed' batch like mine... i sent to Samsung but it got worst. Could not even turn it on. So i DIY it since i am rooted and the warranty does not cover rooted device. And my battery is no longer like what u r going through. If u are not rooted, go for an exchange.
Read this thread i linked, is how we fix the battery problem..

Phone shuts off!! Automatically!!

Hi,
I have now had 2 occasions where my LG OX2 were automatically shut!!
I took it of the charger this morning, screen brightened, all normal. After 5 min. when I needed it, the phone was off. Later I had one more like this. Got to work and after some hours it was off when I needed it! I really don't get it. Battery was full.
I am on 2.2.2, rootet.
Has anyone had same experince??
I had that issue aswell.
Had that aswell yesterday morning, had to take the batteri out and put it back in, to get it back on
Same here.
Hi guys. Thanks for your answers. This is indeed very strange. This could be something that I will not accept for a smartphone this price. I will contact LG.
Are yours also rootet and have you removed anything?
Cheers.
Rooted. Not removed anything at all.
You mentioned that you have rooted the phone, did you freeze any applications?
Same here.
Only happened once and it was plugged into a charger (and would have been at 100%).
Battery pull was the only thing that worked.
I'll add this thread to the bugs thread.
Have not happend to me yet. I have used it for 1 day now. And 3 charges. No problems.
Rooted and deleted some apps.

Nope.

So it seems to happens just on the rooted phones. Maybe the root its not stable yet?
No, i have not yet roted and i had the same problem yesterday. Nothing so far today though.
Optimus S ... same problem!
It seems like Optimus S have the same problem

Mine is not rooted, I had around 54% battery when I left work. Phone rebooted two times during the 15min walk home, once during a call and once when all I was doing was swiping around the homescreens... :/
My o2x rebooted once today, with 50% battery left.. Edit: Mine is also rooted and I have frozen the car home app.
This is very distressing. Being that this problem affects the 2x, rooted or not, then it is def. a hardware issue. Possibly solely a battery issue, or the design to which where the battery is housed (connectors), or simply power hit/miss circuitry design. My advice is, if it occurs enough not to annoy you (meaning, you don't want to deal w/ a return/exchange & don't mind the re-booting) then keep it. I believe that no software patch can fix this & for such an expensive device, I would return it for a fresh unit.

I did withnis this twice yesterday.
The phone doesn't shut down. It is a huge lag.
It happend the 3th time. I didn't pull out the battery, after 20sec that I pressed the power button for the screen to light up, the screen showed.
So it is lagg.
Not rooted. And to make it clear i'm talking about the phone screen not turning on, so you have to pull out battery and power it on again. No reboot.
What?! 20s lag? I was looking forward for quick device since I switch my Rhodium for LGO2X. I hope that this would be fixed soon by LG...
How odd. I haven't experienced this at all, and i've rooted mine and removed apps like F-Secure from my phone (By renaming them, don't worry.)
I guess a good way to find out if it's lag is to see if adb is still working.
Had it yesterday myself, once during charging. Then the powerbutton did work. Hour later I had to pull the battery. Wanted to advanced but forgot to leave USB debugging on. Had it so far only with my replaced unit. The first few days with the original unit didn't show signs of this...
Have to say my first unit wasn't rooted until the day they swapped it. The one I have now has been rooted since day one.

[Q] Help, please! My battery?!

Okay, so.. I have a Samsung Galaxy Exhibit II 4G.
I have it rooted with the root stock from this thread.
With that said, I've had this phone rooted for several months now. Since January or so. Over the course of that time, the phone has run without fault for months. Recently, I've had issues with my battery draining (as well as charging) far more quickly than it used to. I assumed this was an issue with the battery, because there was a slight bulge in it, so I bought a replacement battery that came yesterday. I charged it full (until the phone said it was 100%), from about 5% charge. It took the normal time (as the phone did when it was new) to charge, of just over 2 hours. It died almost completely about 2 1/2 hours later. Currently, I have my phone charging and it's at right around 90%, after just over an hour of charge from 20%. It used to take far longer to both charge, as well as die. What the Hell is going on?
Just a few notes:
This is not the result of heavy usage (for power drain). I say this because even as the phone was idle while I slept, it died on its own accord sometime throughout the night.
My bluetooth, WiFi, and GPS are almost always off, unless I'm using one of them for some purpose, and I haven't used any of those things since the new battery was installed.
There are no applications running in the background, aside from Facebook. I know this because I'm using Advanced Task Killer to kill everything, and it keeps showing Facebook as if it's opening itself for some reason. This is another issue I'm concerned with, so if anyone knows why or how to remedy this, I'd be appreciative of knowing. Otherwise I'm likely to just delete this unnecessary application.
This is not an issue where the phone is reading an incorrect charge over an extended period. It literally is dying and charging faster than normally.
When the phone is rebooted, whether it be through "Restart" (app from Google Play), via the phone Power key, or removal of the battery, the phone drops around 20% battery life when the restart is complete. The absolute reverse happens (it gains 20%) when restarting with the phone plugged into an AC charger.
Is it possible that this has something to do with the root being outdated, or maybe something updated and I'm unaware? I sincerely have no idea what's going on, as this is the first phone I've ever rooted before. I'm sorry for the long post, but I wanted to give as much information as possible.
It sounds like the battery you bought may be defective. Send it back and get a different one.
Yea sounds like you bought a defective battery. Where did you buy it from? Talk to them and see if they'll send a replacement or get another one from elsewhere

Battery issue and restoring completely to stock

Hello everyone,
I have been using a Xperia Z1 for around last 6 months and updated to Lollipop 5.1.1 two months ago. Everything was fine until last week when my phone started to get affected by the battery bug.
The phone works fine and the battery gets discharged in leaps. For example, when I use the phone from 100%, it goes down in the usual way, let's say for 1 hour usage it drops up to 90% which is quite normal. But, when lock the screen and keep it idle for sometime and when I take it back, the battery has dropped a leap, usually by 10-15%.
Yesterday, I was using the phone normally and kept it idle for the entire night and battery has been dropped only from 85% to 79% without stamina mode. That's good. However, when I restarted the phone in the morning, the battery suddenly dropped to 18%. :crying:
I tried calibrating the battery, charging/discharging cycles and removing batterystats.bin. But, the issue is still here.
I think my phone has been affected by the famous Xperia battery bug in Lollipop which means that my battery is damaged. But, before replacing the battery is there anything else that I could do to overcome the issue. Any suggestions are greatly appreciated.
+ My phone is rooted on stock 5.1.1 (14.6.A.0.368) with XZDualRecovery and locked bootloader. If I repair the phone with PCC will it cause any harm or bricking since because of the customer recovery?
Claiming warranty is out of option since the phone has been rooted and flashed with custom recovery.
I don't know why people call it a lollipop bug. There will be a time a battery reaches its end of live. That's what has hit you right now. Your descripte symptoms are from a dying battery. I have seen some dying battery's from me or friends. The battery was holding the charge normally and suddenly no more.
Replace it and all should be fine again.

But, can this happen on a phone that is just 7 months old? Thats what makes me to think that this could be a bug.
I have the same issue, but mine drops to 0% and after waiting some time and booting it the percentage is back up. I have my phone for 2 years now, and the problem appeared in Lollipop also.

It's okay for a 2 year old phone as Lithium batteries wear out with time. In my case, it's kinda disappointing...
So, after searching the entire Internet, I can understand that this is a common issue with Xperia Z1 and Z1 compact and replacing the battery seems to be the only possible solution. I searched EBay for a battery but couldn't choose a good quality one. Can someone guide me on this please?

Your battery is definitely dying and it has nothing to do with roms. Get a battery that the seller claims to be OEM. That's your best bet...

Thanks for the tip. So, I searched for an OEM battery and ordered it along with some tools required for the disassembling. I will keep posted once I replace the battery.

Don't think that it will resolve your problem.
I changed my internal battery about one month ago and when two weeks passed I started to experiment the same bug ? again
It's not only hardware problem, it also software problem, I believe.

You are correct becouse I experience som drops in the range of 5-20% in less than a minute and once 30%. All the time while the phone was in standby mode except once where it did it right in my face (10%). My battery status is reported being fine. I also forced shutdown the phone as per the calibration method for non-rooted phones. Though I did notice dalvik cache wasn't rebuilt and so there is no way to have it refreshed manually except system updates which does this.
Anyway I did remove some apps and did some changes and after this I have not had any sudden drop for weeks. Two of the apps where Truecaller and Facebook official app. Will check though if it was a third one to. I believe one of these or both where playing havok. Especially the Facebook app as it takes liberties I find suspicious, is buggy, can crash the kernel (any app that can do that is doing shady work IMO) and had the addition of a "Video Player" service that was running permanently after you launch the FB app once. I instead use Metal for Facebook now. Pretty much same experience, only 10MB RAM used instead of 90MB and no batter y drain either or any other problem. So in short I believe one of these where the culprits and since many use the FB app that might be the one playing badly with Sony Z1 system.
And If you use Adguard also check if there are apps getting high ratio of ads blocked (or analytics data blocked). Might be some dont get proccessed right in the battery system due to it calculating it wrong. Google Frameworks, Google Contacts, Play Services, Mobilestorage Checker and a few more I disabled the ad filtering for. Though this did not change the battery drop problem previously. It only went away when I uninstalled named apps above.

New battery not solving shutdown problem

Z1 lollipop 5.1.1
build n. 14.6.A.1.236
kernel ver. 3.4.0-perf-gd26777b-00851-ga8b7b55 19 november 2015
It all happened a month ago, after an update, the phone battery registered low and the device reboted, and for the first time in the phone history, I saw, at boot, the "app optimization" dialogue, that kept chewing at what battery life was left.
So, I replaced the battery;
at first start, all seemed OK till I hit an app (whatsapp I think) and the phone displaied the low battery warning and went down.
Same, after a full recharge, when pressing the camera hardware button.
Oh, I also had the discrepancy between the charging icon , which reported 100% charge, and after maybe 10min. 50% and, you know the story.
Now, at the very moment I am writing, after a full charge, 24 hours ago, the phone, without the sim and the SD cards, but left on, registers a charge of 93% (only wireless on, to invite some disharge); of course I cannot check the watsapp, but I took some pics, and the phone stays on.
What do you reckon, I am bugged, as android 5.1.1
should I hang on the phone, which, by the way, performs(ed) pretty well, even though marsmallow is not an option, with the 2GB mem. at least in a bog standard state (i.e. not rooted)?
Thanks
A little update: after two more hours, I started using the browser, and after viewing a couple of pages, the phone swiched itself off.
Now, the charging icon, visible, when phone is off, show a 1% charge.
So, the software battery meter, must be well off the mark?
Last addiction: after an hour, the status light is green (phone charged?) and the charge icon, displays a 100% level.
It's your say, now.
I have this problem and battery replace didnt solve anything here too, but I'm on nougat. I hope someone know a solution for this.. But I think It is some kind of hardware problem.
Little update: after recharging, I switched the phone up and let it play some video on youtube;
well, after maybe half an hour, it went down, and as soon as I plugged the charger in, the icon showed 80% charge, which I allready experienced, dismissing it had a fawlty reading, but, with some afterthought , would be in line with the actual battery drainage ( remember that without any activity it stays on indefenetly) and is, as if, some internal mechanism -either hardware or software, is programmed to switch it off at that precise level.
Just a thought, is there somewhere, the level of battery disharge can be set, at our discretion before the device shuts off, say 15%?
I do not seem to find this specific setting, currently.
It is less credible, as time goes by, to think of it as a specific device/brand problem, given the fact that all the major players ware, seems to be affected, and allowing for differences in platforms, the common denominator would appear to be the software itself.
Exact same problem
Some time ago, I replaced my Xperia SP's battery.
The "used, like new" battery I ordered was as bad as the one that was to be replaced, maybe even worse.
I complained, got another-one. This other battery works great.
Remember: There are no "new" batteries out there, just used-ones.
Some are still good, some are dead.
I don't know where replacement batteries that are new should come from... Sony has never sold them as spare parts. I don't know of any company that produces batteries for Sony phones and sells these batteries on the open market.
I only know of third party spare parts for iPhones. Apple has sold only like 20 different models since 2006.
Sony? More like 100.
Producing third party spare parts just isn't profitable in this case. That's the reason why there aren't any.
Any seller who claims to offer "new" batteries lies. At least if he didn't take them from some never used devices.
I'd be HAPPY to be proven wrong because I also need a new battery for my Z1.
Besides, it's no wonder all our phones' batteries die at the same time. They are all the same age and have had more or less the same amount of charging cycles.
Also, it's no wonder they all die the same way (suddenly empty).
They all (more or less) came out of the same factory.
It's like with cars, same model, same problems.
A Peugeot 206 always has problems with the Zylinderkopfdichtung (don't know the English word, the rubber thingy in the motor that keeps water from mixing with oil), some stuff with the wheels or the exhaust flies off because of rust... for the third time in 5 years...

Your allegations, are worth investigating.
[solved]
Very important updates.
There seems to be an "xperia battery bug" which kicks in at every battery change.
After having done all the calibration stuff, I re-opened the phone and took the battery connector off, while the phone was on.
Then, did the same, with the phone off.
After three or four days in which the phone did not seem able to start, (rebooted at the first stages of switching on) the phone magically booted up with, and what's more important there was no dicrepancy, between the battery charge level, shown when you plug in the charger, with phone switched off, and the charge level presented by the software, once the phone is on.
So, do not give up your still worth device!
Only thing I noticed now, is a sligtly faster battery consumption, even in stamina mode;
could it be related with the post above?
Maybe a new custom ROM could fix the problem, now that the phone seems stable.
Similar problem.
Phone shuts down when 2 to 3 apps are working simultaneously. It first heats up and then suddenly dies.
Secondly, it sometimes dies on 60% and other days it can work till 1% too. Sometimes after a reboot, it shows the battery percentage abnormally.
I love this phone so i m not planning to throw it away. On the other hand, i cannot find an original battery in the market.
Just chuck a suitable battery in and do the procedure I described.
My battery is not original either, so no problem.
As far as the battery consumption, it seems to be better now, after a week of use.

Nexus 6 Battery Issues

Hi there, I just purchased new a Nexus 6, love the phone, seems that all new phones all looking like a Samsung or iPhone which is not good.
The phone just purchased is new out of the box from eBay and shipped over from Hong Kong.
When the phone is idle I get a good day out of it buy when in use I can see the banner count dropping very quickly, if I had to use it for an hour on the phone I would guess that the banner would drain to 0. If I play around with the phone I would assume that it wont last more than 2 hours at the most.
Is this a common issue with the phone or should I assume that the phone has been sitting in a warehouse for the past 4 years with no use causing an issue with the banner to deplete so quickly.
I was also wondering if it is was worth replacing the battery or is it an issue with the phone?
A few days ago I noticed the phone shutting down when at 15%, since then I re-booted the phone in safe mode, worked with it for a few hours, then back to normal mode and it seems that it now drains to 0.
Any help appreciated.

4 years ago, my Nexus 6, out of the box, had battery drain, mainly caused by the amoled screen.
I installed the No wallpaper app to make the background black and use only apps with a black or dark theme.
Since then I can use the N6 in any case from 9 to 5.
Now using Beltz-rom with built-in black theme and ElementalX kernel. Rooted with Magisk 1600.
Although my battery is 4 years old; still working. I've never used quick charging only slow wireless charging.
Replacing the battery is a hassle because there's a lot of glue. But when my battery dies after more than 4 years use, I'll try to replace it. But probably I will buy the new One Plus 6.

Assuming you're on stock 7.1.1, try to boot into bootloader (fastboot mode) by powering off and then rebooting by holding down power button and vol. down button, cycle into "bootloader logs" using volume down button, and then holding power button for 15 sec until it reboots on its own back to "GOOGLE" logo and then let go. This resets the battery calibration and should fix issue--if not, replacing battery can be done--watch YouTube video before doing it.
