Hello, im new to these forums so first of all excuse me if i do something wrong.
The problem: 3 days ago i got myself a Samsung galaxy note, switching from 3 years HTC. Overall i am in love with the device, but the battery is draining very quickly and with that i mean 1 to 2 % in 5 minutea or less. Most of the time i keep screenresolution at its lowest. I have to charge the phone 3 to 4 times to get through the day. It also drains alot when in standy, like 10% hour.
I'm at the end of my terms, i hope someone has got a solution, even if its temporary i'll be happy!
Kind regards
I have the 3g version with wifi. In airplane mode and standby, overnight for 10 hrs it drains 1% only. .... use better battery stats app from xda to check for kernel wake logs and what apps are draining the juice

Are you talking about the Note, Note 2, or Note 8.0 3G?
Is the 'phone' new or used?

I assume i have the note, i havent seen anything about 8.0 3g in my device or its box.. the phone is used and 1 year old
.
you're in the wrong forum man...this is for a 8 inch tablet, not a phone
Lol that's what happens when Samsung call so many devices note , note 2, note 10.1, note 8.0 people see a note forum and presume its for their device.

Ah. Thought so. You need to replace your battery. Do whatever you need to to find out exactly which Note you have, then buy the largest capacity battery available for your phone from Anker *that does NOT require a custom battery cover*. Anker make reliable batteries for a good price.
Bro, mine was even worse. I just got the note 8.0 and hadn't used it up to month. My battery went up like superman when I plugged it for a charge and dropped like flash when discharging! It was really bad man. But I had it fixed man.
#requirements#
1) A rooted 8.0
2) Download Battery calibration from google playstore
All I did was to allow the battery to drain completely, then I plugged the charger and switched it on. I allowed it to charge to 100% without interrupting.
Then I opened the battery calibration app and clicked on calibrate battery. That's all.. My 8.0 is back now. On standby with H+ I get a 3% drop per hour. Hope it works for you. Pls click on thanks if it does. Thanks
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...
TLR Anyone willing to see if their tab pro drains battery when fully powered off. Like overnight when you're sleeping or at work. Thanks
Hi,
I got a 10.1 tabpro back at the end of Jan. I thought it would be a massive step up from my Nook HD+ (rooted) but it's not. Not only is it slower than expected the battery life is atrocious. Samsung advertises over 2500 standby hours for their 10.1 tablet, I get 200. Also I get about 6 hour video, mp4 files, not 10 and I don't like a bright screen, I know companies exaggerate but this is daft. But it's the standby that's a problem, having to charge it every few days in case I want to use it is a big step down from my Nook.
It's been into Samsung repair 4 times now and I'm currently at a dead end.
Problem
It loses 0.5% an hour on standby even with wifi, gps, updates off etc
It loses 0.5% an hour fully powered off. Fully powered down. OFF, not on standby. Just to be clear
Compare this to my nook with a smaller battery capacity which loses less than 1% a day. I've tried turning off other android devices (mobiles & tablets) and none lose battery over 12 or 24 hours when powered off.
Current situation
It's been in 4 times, it has been returned with a squeaky corner which they've failed to repair and the retail box is torn and tatty like they played football with it.
I've now been told
I have spoken to our product specialist regarding this and the decline in battery life over the 24 hour period is not considered to be unusual. In the 12 hour period where the tablet was powered on, even though the screen is off and apps closed down the tablet will still be transmitting, searching for system updates or connecting to networks or wireless. The 12% decline in battery is considered normal for this kind of activity.

This doesn't address that wifi, gps, updates etc is turned off and drain whilst it's powered off. I responded 2 weeks ago but there has been no reply.
Feedback please
1. I've been all over the internet. I've tried greenify, I've tried battery calibration, there's a ridiculous amount of bloatware that I can't delete but I've reduced apps running as much as I can. Does anyone have any other ideas?
2. What's your tablet like, does it lose battery life when powered off? I've seen people posting on here about their 8.4 inch tabpro and they've put screen shots showing better standby battery life than my 10.1 with a much better battery capacity.
I've attached some screen shots, less than 3 days and it lost 33% doing nothing on standby.
I would really appreciate if anyone could feedback on battery life when switched off, is someone able to test theirs for me?
Many thanks,
Anna
Is someone willing to see if their tab pro loses battery even when powered off?
Thanks
Uh-oh. I hope this is unusual and anomalous. I'm actively seeking a replacement for my HD+. I want to love it. I *SO* want to love it but it infuriates me that the browser crashes so often. Yours? Which ROM?
Nook is fine, It's the Samsung that's utter pants. Nook battery loses less than 1% a day on standby and screen is good. Surprisingly I thought the octo core samsung wouldn't be laggy but it is, it's not that much better than the Nook.
I have cyanogenmod 11 I think. Yes the browser crashes but that's partly because many sites are badly designed and web 2.0 is badly implemented and I use Dolphin because I like the format however it's a terrible browser for crashing. The new Guardian site I struggle with on tablets and mobiles no matter what browser for example.
Anyone willing to test their tabpro for me????
I'm actually on my 3rd day with my 8.4 it's 10:35 pm and I still have 35% left

I don't understand. 3rd day of what, off, on standby, has it been used?
Mine loses battery at 0..5% an hour on standby and fully powered off. I'm trying to establish if other tab pro's have the same level of drain on standby and powered off. Can you give me more info please? Thanks

Take the rear cover off, disconnect the battery from its connector. Bring it to a repair shop where they can do a solder work. Ask them to re solder the battery connector, this rework only takes under 5 minutes. It will fix the problem of battery quick discharge. If the problem is still the same, you only need to replace the battery, cost only around $30 for new battery.

Thanks but it was only a few months old so well within warranty.
They replaced it with an tab s 10.5 (no more tabpro's available). Tab s gives me the battery life I expect and speed. Big difference between the two is the tabpro used up a lot of battery with 'tablet idle', well over 50% whereas on the tab s it's a few %. I think the tabpro didn't quite deliver, it was discounted quickly, the software wasn't right plus squeaky case, but so far imo they seem to have got it right with the tab s. Despite the lower capacity battery and bigger screen it lasted me over 5 days and that included setting up and installing apps. The tabpro by that point would have been long dead.
I'm glad you get a new replacement but this's a common problem of Samsung tablets . Be aware of this problem is the future of battery quick discharge. Most users just simply think this is a problem of battery.
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 guys!
I have a serious problem with a used A5 (2017) I got from some friends. The battery life is abysmal. I already changed the battery and it didn't change anything.
It is running on Android 8 Oreo. The most serious problem, I think, is that the phone even discharges when it's powered off. I tried using the latest hadesrom, but it didn't changed a thing. Lifetime is around 12hours, doesn't matter if I run some apps or just let it lie around in standby. I tried factory rests and some battery saving apps... nothing works. Is there any way to get better battery life? Thanks in advance!

You could try the naptime app. But I don't think my battery life is any better than yours.
The a5 2017 has a famously good battery life.
I am not a heavy user - make and get few calls and mainly use it for receiving emails and a few texts plus a bit of web browsing.
Occasionally listening to podcasts.
3 days battery life is easy for me - reckon I could get 5 days if I just left it sitting quietly.
If it's going flat quickly even when switched off, it sounds like a fault somewhere.
Don't know what else to tell you.

I never tried letting it sit, but if I just left mine alone it would last for days too. But if I am gaming on it, it will go down to around 50 percent at noon.
wow - 3 days life battery!! I can hardly get to 2 days, without heavy us - but I would never try to change the battery -> sounds too complicated
One thing that is worth looking at is the Always on Display (AOD).
I found it sucks a lot of power despite the claims that it 'doesnt use much'. It seemed to use around 1% an hour - I guess thats around a quarter of your battery in a day. So unless you find it useful either turn it off - or set it on a schedule for when you actually want it to be on.
Battery life is always sujective and depends on what your phone is doing - gaming will burn through a battery like nothing else.
The OP said the battery drains even when the phone is switched off - That sounds like a hardware fault. The battery will gradually drop when switched off - but it should take months for a healthy battery to drop much if the phone is switched off.

1 percent an hour doesn't matter to me lol. I am a heavy user so I charge every day anyway.
