Hello, this is the battery graph of my daily use of less than a year old Mi 11i with basic apps like whatsapp and facebook. Situation has been the same since the day I bought the phone. I should have returned it the very fast day I bought it. I cannot send it to repair now because then I will need to buy 2nd phone for work. I didnt expect 700 euro phone will have faulty software or battery out of the box. I have to turn on airplane mode during night since it will drain 50% battery. Overall phone is not useable and I am wondering is there an battery upgrade that I can install by myself?
The forum for Mi 11i is here

Wile browsing net the battery drain from 100% to 90 % in ten minutes :crying:
I really begin to hate this tab
My tab is tag s 8.4 lte
I have really great battery life with my tab s. Can you screenshot and post your battery stats? Its in settings, general,battery. That can also tell you have much battery is draining from certain apps. I installed a custom ROM with debloated apps and I get about 11 hours of battery life. It could be some background/user installed apps that could be draining your battery. I would suggest deleting apps you don't need and disable preinstalled apps that you don't use. Hope this helps!

Which ROM do you use for such great battery life? Mine's really poor but I don't think the warranty will cover a replacement. Considering rooting and ROMing, but I want to keep the multiwindow so I'm not sure what my best option is at the moment?
I get fantastic battery life with my tab. I use it pretty frequently and have never been below half battery the two months I have had it. I charge it every night though and it is the 8.4 wifi only version so I'm not sure how much battery life differs on the lte model although I'm sure it uses more juice (the lte model). Overall my battery life is phenomenal though, especially with the sky high kernel
My T800 is not bad either. Its not iPad Air battery efficient but pretty good nonetheless. I'm getting about 6.5 minutes for every 1% while web surfing, email, etc; higher if just watching movies with the wifi off. I also picked up an Anker E5 battery as a back up so battery life is really a non issue for me now.
I had very bad battery life on my tab, similar to yours. I sent mine to the service center (**** experience from the one in singapore). They opened up my tab and reconnected the mainboard to the battery and it is better now although i am still monitoring it. I just got it back yesterday.

My battery life was pretty bad also until I turned down the brightness. With this type of screen it will drain your battery if you have it at full brightness. Even having the brightness at 50% it still looks really nice.
I don't have any problems with my battery life. Lasts an entire day of heavy use and sometimes 2 if I don't use it as much.
last device i buy from samsung! bad battery life bad bluetooth connection hardly can connect my bose soundlink headphones, and the most annoying thing is the wifi sometimes it doesn't connect and sometimes it shows an established connection but no internet nothing can connect to the network!
i bought it 4 days ago and will gonna sell it online since there is no return policy at samsung shop in dubai
best thing is to buy a nexus 7 like i did for my son.

Everything works fine for my tab s 10.5 inch. And I got mines from Walmart...
New here and new to Android. I'll try to make this as brief as possible:
Two weeks ago I purchased a used "refurbished" Galaxy Tab S 8.4 with Lollipop installed. I very much wanted to try to make the slow but gradual switch from iOS and thought this would be a good place to start.
Battery life is horrendous compared to iPad. Here is the issue broken down:
Powered on. Battery drains at the rate of 1 percent an hour in standby.
Powered OFF. Battery drains at the rate of 1 percent an hour.
Powered on and using for web, video, etc (no games). Battery drains at the rate of ~10 percent every 15 minutes or so.
What I've done:
Wifi OFF except when in use
Location services OFF
Sync OFF
Bluetooth OFF
Screen at just below 50 percent
Wakelock detector finds some activity (mostly Android battery "WLAN" monitor stuff)
Did full restore
Most importantly: I REPLACED THE BATTERY WITH A BRAND NEW ONE and am seeing nearly identical drains as I did with the stock battery that was two years old
I have scoured the internet, rooted the device to try to kill any rogue activity, and "reseated" the battery connector 3 times.
Can anyone tell me WHY this battery is losing one percent an hour while completely powered off?
One clue is that, with everything turned off (listed above) the battery drain is nearly identical when off as it is when it is "sleeping" which would indicate...well, something.
I'm frustrated that I have been focused on fixing this issue rather than enjoying my "new" Tab S.
Any help would be greatly appreciated.
Thanks!
EDIT: I have read through other batter drain threads here and, although others share similar problems, don't have an answer. Maybe there is no answer?
I had a similar battery drain (when the device was off) 1.5 years ago with my couple of months old tablet. Had to take it to warranty repair twice, on the second attempt they changed the battery connector and the power circuit (if I remember correctly), and that was enough to fix the problem.
If the tablet drains the battery while completely off, it's clearly a hardware issue.
I'm thinking hardware has to be the culprit too, at this point. Very frustrating as this is a used tablet and out of warranty. I have done everything possible to try and get decent battery life out of this thing to no avail. I'm loving android but have a bad taste in my mouth as to their hardware. Should I keep or just get a couple hundred bucks on ebay? I'd be thrilled with this if the battery life came anywhere near the iPad mini.
The 8.4" is known for having a problem with the battery connector (maybe flexing of the case makes it loosen), some people have soldered the battery wires directly to the motherboard and say it fixed the problem, Samsung knows there is a problem with the battery connector according to some service centers, one service center actually fitted a more heavy duty connector to fix one problem according to what i read.
John.
I would contact the seller and try to return it and then get one from a different seller.
~ Assuming you didn't buy from some random ebay seller who has fake rating >.<
Hi,
I've been using this Tab S since July 2014 and been very pleased of it.
I only use it every night for Web browsing or watching movies.
Not any games or any social network or anything draining the battery.
Average autonomy was around 7 to 8 hours.
9 months ago it has started to drain a little bit more and especially when off (totaly off, not in sleep mode)
Before that event I was turning it off at night and 24 hours later the battery level was exactly the same. (zero percent of drift)
Then it started to suck a little bit every day: 1%, 2%, 3% each 24 hours when completly OFF.
First thing I've done was to make a wipe cache/data and restore to factory settings from recovery mode.
It didn't help.
Then Samsung released Lolipop Upgrade so I did it.
It didn't help any more.
So I ordered a new battery to an official dealer and replaced it.
You know the answer.... didn't help.
Then Marshmallow has come and I did it.
.... idem.
So as electronics and automation technician I am, I decided myself to do some measurements.
I opened the Tab S and checked battery voltage when off every hour with a high accuracy Fluke D.M.M.
And I found that it was loosing ~34mV every 24 hours, which makes the 3% loss.
(Boring calculations just for knownledge : LiPo Vmax 4350mV - LiPoVmin 3200mV = 1150mV corresponding to 100% capacity.)
First thing I did after that was to make the same check but with battery disconnected to the Tab S.
And you know what? not even a mV drained in 24 hours when not connected to Tab S PC Board!
Then I measured the resistance between + and - socket on the PC board : value between 800KOhms and 1,2MOhms.
Same values when I crossed the wires.
Theses values are too low, I should have found many many MOhms.
I've also checked the battery connector that some other guys said it was loosy or bad soldered: that's not the case but I've soldered it.
same problem.
MY CONCLUSION: it's a hardware problem.
Maybe it's a drifting component, probably a capacitor which as lost insulation, or a defective diode.
Unfortunately I don't have the diagrams of this Tab S and can't diagnose it.
Is there on XDA any guy from Samsung Tech Support who can help me?
No answer?
Anybody has Galaxy Tab S 8.4 diagrams?

i had the same issue Android – Marshmallow Android – Lollipop etc battery life sucks on the upgrades.. The battery would not last more than 3/4 hours, it was a pure joke. Best thing is to downgrade to KitKat XXU1ANF8 since my downgrade battery easily last a few days of heavy use.

Hi all and Happy New Year.
The problem is that while my T-700 is turned off (not screen off) and having installed a new battery (doing all the preparations needed, like reset to factory settings, clear cache, recalibrate new battery), in two days time the battery from 100% is COMPLETELY DRAINED like a freaking 0%! And allow me to repeat ...WHILE TURNED OFF!!!
The battery is brand new, and the tablet is "untouched" (meaning unrooted, no UB, Knox is 0 and I have installed only the Official OTA's provided by Samsung).
WTF???
I've contacted the place where I bought the battery and they told me that they will send me a new one, BUT that was the exact same reason why I bought this one and changed my battery in the first place (of course I haven't told them that) lol.
Could this be a hardware issue, or was I so unlucky that I just happend to buy a "dead" battery?
Any ideas? Plz help, I'm in desperate need of my T-700 for working purposes...
Thanx in advance!
ANYONE??????
I can't say my battery is brand new, but i have been having battery issues lately no matter what rom I use or if I return back to stock. I have no idea why it would be doing so though.
Do you think we can blame the tablet's motherboard? Cause it's the last thing I can think of that would be responsible for these issues since software obviously isn't (At least in my case I hope for a DOA battery issue fingers crossed..).
Anyway, I've ordered another battery (e-bay) that would be arriving in approx 3 weeks. We'll see...
If no luck again, then a repair center will provide the appropriate answers...
I have the same issue with my Tab S SM-T700 and I have tried flashing many different ROMs, the problem still exists. I would suspect a hardware fault, either the battery management IC or some other consumer that doesn't power down properly. Don't think this can be fixed without a new motherboard, at least it's still usable plugged in!

I have purchased several batteries for my SM-T700 from different suppliers on eBay. Apparently, there is a big market for batteries pulled from old devices and relabeled as "new". Based on the poor specifications (I.e. battery capacity, battery life) I suspect that not one of them was actually new. For example, one battery held so little charge after just 16 discharge/recharge cycles that I had to replace it. Perhaps, you have a bad battery.
There is an option somewhere in the settings to turn off wifi when the tablet is not in use. This solved this problem for me. It's the misbehaving apps that "call home" or use other resources while your tablet is supposedly asleep. While it's possible to hunt down at least some of these apps, it's kind of hopeless because some of the worst offenders are google's own apps and services. When wifi is not available they all go to sleep and the tablet can now stay idle with screen off for days without draining battery. Before I enabled this option, the tablet would literally drain 1 percent of charge per hour even though not used, so after two days of no use 50% was gone.

True... But previously bought battery was not from ebay but from a retail seller... The newly bought one will be from eBay. I'm still waiting on that. Will inform when it will arrive...
That was it... Main board problem... Need to spend 200€ (which of course I won't) in order to fix it. Still, I can work with it as long as it is always plugged in... Unfortunately it was not a battery issue...
Can someone tell me some good battery replacement for zuk z2 plus which can be purchasable in India.
Unfortunately there is no Lenovo service centre near my place and I really need a battery.
Hear my story -
For all these years I was in the dark. My phone automatically shut downs for almost 2 years whenever I try playing games and now it even without playing games it first freezes then the screen starts flickering and the phone restarts. I searched for many solutions but never found one. Then few days ago I checked a post related to battery on q/a and installed the battery app from there and checked my battery health. After seeing it at 28% I am 100% sure that the issue is because of battery. For all these years I stopped gaming and occasionally played in my moms phone. I really want a battery now and would appreciate for ur help
search on Aliexpress, you will get a New user bonus coupon , after applying that coupon battery will cost you Rs.400, it will take 20-30days to deliver.

Hi all.
Am hoping someone can help or advise regards to this query.
I've had the red magic 6s pro for a few months (purchased brand new).
I've found the battery life to be ok ish but when I checked on accubattery, the battery health seems to be degraded more than I expected. See screenshot.
Is this normal? Should I trust accubattery with this stats and go to support team about this?
Many thanks in advance
same problem, phone is 6 months old...
I'm starting to feel that this phone advertised battery capacity is not truly 5050mah. So if we have similar readings, then maybe it's around 4400mah?
I'll guess we will never know unless we have a collection of results from other red magic owners
Same, 88%.
I always charged 20% - 80% with slow speed.
And now my phone heats up even with slow charge.... So bad company
Battery degraded already, memory leak, chinese users in forum says the updates are garbage making phone only run hotter.
Never again will buy gaming phone...
Edit: dont mind normal/overcharged stats, they are 10days old or so, i used accubattery pro for 6-7months.
I recently switched to batteryguru.
