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
Well ever since I've got this phone I've been pretty impressed by the battery life. I get bored at work and tend to surf the Web or play games on my phone. My record was 29 hours without a charge with heavy usage but I didn't think to screen shot and share. But this round I've been playing clash of clans pretty heavily. Specifically in the last 4 hours I've been on the game for about 3 straight hours. I just wanted to see what other people's results are too.

I was using stock rooted KK, stock kernel, and stock settings. I broke down and upgraded back to lollipop in hopes of xposed being updated soon. I missed the features of lollipop. I was getting better battery life on lollipop so I'll put an updated picture after work sometime tomorrow.
How are you getting 29 hours? I updated to the nightly for CM12 and I went from 100% to 65% in about 2-3 hours. This is frightenly fast and enough to consider taking my 1 day old Note 4 back.
Cool thanks and any kernels used or just all stock?
Pretty well know if you're using Wi-Fi it'll help with battery life and taking back a perfectly good phone because you aren't getting the same results as someone else is crazy. Heavy user? Nah not really.

I use wifi a lot through out my day but there is about 4-5 hours on mobile network using Pandora
I'm a heavy user with usually no Wi-Fi available. I use my hotspot a little during the day, torrent sometimes, surf my usual forums and sites, and usually a lot of music through bt speaker or ear buds. If I get eight hours I'm happy and I do. My phone has never died. I'm on lollipop.
I usually average between 5-6 hours screen on time on mobile data & went as long as a little over 7 & half hours screen on time on wifi.

wow... I'm really surprised how long your batteries last. My Note 2 lasts 3-7hrs on the original battery and 10-18 with a 3x zero lemon. I got a S6 Edge the other day and the battery life doesn't make it through a festival day so I'm giving it up to get a note 4. People I talk to get excellent life with theirs. But why can't sammy get it together with the battery situation?
If ur on WiFi ur battery life will be great I get 12-14 hrs on network with 4-5 hrs screen on

My girlfriend has the S6 and she can't even compare to my battery life. I'm not sure why either. Note 4 is a bigger screen and I'm on my phone more and I still out last her battery. But then again hers is unrooted and bloat packed. Maybe when she gets root and I optimize it some it'll improve.
Bigger battery helps a lot. Stop all sprint apps. Take it from there.

Note 2 had the best battery life ever hands down, & yeah been hearing a lot of horror stories about the atrocious battery life on the S6E. I was almost thinking of just giving my girl my Note 4 (she still has the Note 3) & using her available upgrade to grab the S6E on a 12 month lease, but after hearing ppl complain of only getting 2-3 hours screen on time out of it I quickly changed my mind. 2500mah sealed battery powering a 2K screen is ridiculous & Sammy should've never made the battery non removable.

idk about best battery... When I'm on a debloated stock rom, I get 2-5hrs on a fully charged OG battery. When I switched to a ASOP based lollipop rom, I was getting 7hrs+ out of the OG battery, but then it started freezing. Now, my note 2 is not really charging. I'm hoping with a Note 4 + zero Lemon battery, I can get 14hrs+ out of it.
I absolutely love and adore this tablet. I actually bought it refurbished a couple years ago and it still operates smoothly.
However, I notice that the battery drain is getting a little bad. When I fully charge it and look at the battery stats it usually tells me I have anywhere from 3 hours to 6 hours of battery use.
I'm a heavy tablet user so maybe I have been using the battery a lot.
I notice that there are battery replacement kits online. I'm really freaked out about the idea of changing the battery on this because I don't think it will be as easy as changing the Nexus 7 2010.
Can anyone provide me a bit of feedback on this? Should I be considering changing the battery at this stage? Should I even attempt it? I'm really afraid of ruining my tablet.

I don't think, that this is an indicator for getting a new battery for your tablet. Since Marshmallow the battery statistics on my flo show me exactly the same for the first few hours after fully charged. Let it run about some hours and us it normally - and you will see later a new calculation for about 3-4 days...
So it looks here since using Marshmallow.
Okay, I'll hold off on the battery for a bit.
Does updating apps put a damper on the battery as well?

Try this, always charge it powered off. My battery stats have been completely off since mm but by chance I discovered that I get my normal 8-9h SOT if I turn it off before charging and power it on after disconnecting the charger. I've had mine since late 2013 and still see fantastic battery life.
I think the batter is the weak link in this phone. Actually, I think it was that in my Note 4 too. After a good year, my phone started bootlooping and it was the battery's fault. I am not too confident in Samsung's batterys, not because of explosions but because they seem to be not the best. The problem is, if we want to change Note 7's battery, it will have to be done at the service center. So I'd like to keep the battery in good condition for as long as possible.
I have read it is best to avoid fast charging. I also read it is best to keep the charge between 40-80% and not let it charge over night. And to only let it drain to 0 and charge to 100 once a month to recalibrate it.
Do you guys think these are good tips for the Note 7?
I also read that first time I should have let it chargefor 5 hours, which I didn't first mistake there? Thanks everyone.

From what I have researched from chemical engineers who design batteries etc the best thing to do is not allow the battery to discharge below 20% and not charge it over 90%. Fast charging apparently does shorten battery life but all charging methods shorten battery life. All about heat, so they say? In 'normal use', whatever that is, a typical mobile battery could last years?
In thinking about this I have owned since the early 80's maybe over 100 mobile phones and 100 other mobile devices and have never replaced a battery yet? I have friends and family still using some of my hand me downs and they are still going strong.
Appears a very hit and miss science?
Ryland
I am pretty sure I count as a normal user. I also don't think I exposed the Note 4 to too much heat or did terribly stupid things with the battery. Did I just get a bad one, maybe.
It sounds to me that you've been paying too much attention to the battery, stop worrying and you'll enjoy the phone even more.
never let the batt go to 0%, charge max at 90%, thats all you can do, and, dont worry too much, enjoy your note 7
This is off of Samsung site...
Cell phones, originally used for little more than calls and text messages, have evolved into all-in-one entertainment devices. Your smartphone plays videos, music and games, and many include lightning-fast Web browsing and a robust app library. Use these features for more than a few hours, though, and your phone's battery charge may not last longer than a day. You can coax more life out of your phone by charging the battery correctly and tweaking a few power-hungry settings.
Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

I've researched this and tested it for myself not saying this is the answer. I use to go 100 to zero with note 3 trying to see how far I could go screen on time. Biggest mistake I've read from Samsung and makers of lith batteries to not let it go below 60 amd it's ok to top it off as often as possible. Leaving on charger doesn't effect them due to them never fully charging they trickle charge my wife does this every night with note 4 no issues same battery for a year. You get 500 cycles of charge if you deplete 100 to zero it makes the battery unstable when hitting zero lith don't like it. You get 2500 cycles if you do the 75 to 100. I've topped off my note 7 every day lowest going to 60. I play music for 3 hours walking outside only lose 2 percent of battery. Using hotspot I lose 5 percent in a few hours all been the same the way i charge. I had 2 other note 7s I did the opposite. In a week I would lose 20 40 percent battery with hotspot music not as good either. Learn the mechanics other the battery how they work wiki it. Look at the science not opinions or articles. That helped me in the long run. I keep a Poweradd Apollo with me just in case.

Well if Samsung put that info on their page it really about says it all.
Back to stationary phones I guess. I don't want to have to take this phone to the service centre in ten months or so.

Have you read the replies here?
No device can go forever without an eventual battery change. As I said I have owned hundreds of mobile devices spanning FOUR DECADES and have never replaced a battery.
How did you arrive at a 10 month replacement figure?
Ryland
Yes, mostly they don't agree with you . And ten month figure from my experience with Note 4. At 10 months it started being weak, then after a few more months, bootlooping started and it was just because of battery. I love Notes but just don't think they have good batteris to begin with.

If you have a doubt regarding a mobile don't buy it especially an uber one like the Note 7 etc. If you are very concerned about battery and its going to cause you worry go for a brand with removable battery. No one can asses how you use your phone and how long the battery will live.
Sounds like you had a bad experience with your previous mobile and that has caused you some anxiety. All one can do is relate our experiences to you and hope you can make a judgement call based on others opinions?
I have zero reason to suspect the battery life of the Note 7 to be any weaker than my previous mobile devices. Only time will tell. The battery on my crystal ball needs charging.
I wish you well.

I gave my son my note 3 when I got the note 4, the note 3 is now almost 3 years old, and the batt is still reliable, not as when new, but very dependable
I try to plug in my phone when the battery hits 40% and charge it up to 80%. I dont get to strictly follow it but that's the best way to preserve battery life/performance

Note 7 supports Quick Charge 3.0 or 2.0 or ....
My battery drains too fast.. and I disable the features and not play games..
I have this only 2 years..
If I have 15%.. it was going down to 0% so fast..
maybe it was caused because of the new updates?
Try and use it until it turns off and then fully charge it while it's still off do that a few times and see if it gets any better. I spotted something online which suggested this and it helped mine a little

Yeah to be honest mines from April 2018 and I still have to charge it twice a day sometimes but if it goes off at 15% the full charge thing seemed to help. The accu battery app, said my battery around 80% guess there still alot of stuff running in the background not sure what phones expected battery life is but their only covered by 1 year warranty I believe which probably says alot and the s9 exynos is known to be worse than snapdragon chop for battery
These new Samsung devices have the worst battery life around. Every single update it gets worse. This is Samsung forcing you to pay for a new device which will be exactly the same.

I don't think so, my friend's note 8 last a lot longer than my S9. Maybe it's an issue with the S9 itself because the S8 had longer battery life since the beginning.

If you're aware, Samsung flagships get 2 years of major updates, one year of monthly security updates and one year for quarterly security updates, which equals 4 years of updates, and if you add the first year before receiving the first major update, it's 5, similar to iPhones, and since iOS doesn't bring a lot of new things with their updates, it's basically the same thing.
I'm having so much fun using my S9 and I never got bored even after 2 years of use, and now I'm waiting for OneUI2.1 ? It's true that battery life isn't great but my friend's iPhone X is worse than my S9, so it's a normal thing after 2 years of use, at least for 2017/2018 flagships.

Come on mate, I also have my s9 from launch, do you seriously think that 3000 mAh is still at 100% capacity? Clue, it's not. After so many long charge cycles, I'd say it's only around 70-75%, equivalent to 2100-2250mAh. Atleast you still got a fast charger that comes with the phone. I'd rather not complain considering the screen is beautiful.

This is totally a software failure.
I am a beta tester and when the first one came out for android 10 the battery life was like when i first had the phone. Lasted all day long. As they rolled out more and more beta updates it got worse again.
This had been one of the worst devices for battery life ever since they updated it.
Hello everyone. I've just bought a brand new Galaxy S9 few days ago. My first impression is awesome. The device is lightning fast despite having 2-year-old hardware. I am totally amazed how Android evolved over the years. Coming from a Galaxy S7, I am more than satisfied with my new phone. However, battery life is becoming a concern for me, as I get more and more familiar with the device. The problem is, phone only lasts half day, at most. I can only get 2-2,5 hours of SOT which is unacceptable for me. I upgraded from my S7 primarily for better battery life. I use most of the smart features like AOD, High Accuracy Location, Edge Notifications, 2K resolution etc. and no power saving mode. Can someone explain how can I increase my battery life without sacrificing all these features?

Yeah, brand new dual sim exynos version.
Its down to the software i am totally convinced.
Samsung needs to fix this urgently. It has been going on for at least 2 years and still no fix.
My s9+ drains super fast within minutes once it reaches ~25%. And the "best": if I connect the charger then, it wont charge the battery, but drains even faster to 0%!!! I need to restart the phone.
Tried a full wipe, but no changes!
Samsung needs to read this topic and sort out this mess.
S9 had terrible battery from from the launch. It's the only reason why I regret buying the phone. At least I adapted to terrible battery and learned how to use my phone less so it can survive full day of battery life.
2.5-3.5 screen on time with light tasks only and constant battery saving measures is terrible in my opinion.
Then I bought Galaxy Watch and crippled my battery even more when it connects via bluetooth, it drains so fast it became countdown timer

That's what I was trying to say.
When I first got my S9 I was getting only 4 hours of screen on time while my friend was able to get 6-7 hours on her S8 and she was using it for 1 year at the time. Also every tech website mentioned that the S9 was noticeably worse than the S8 when it comes to battery life.
I got used to it though and I'm keeping my S9 until it stops receiving updates at all.
