Battery Charging question

Hello all, I would like to know what % to start charging my phone is better to the battery? it's draining so much and there is no extra battery for sell in my country yet.
I did search many posts and all answers are different. I am so serious only this and I hope I can have a better way to keep my battery longer... thanks for your attention.

it's usually not good to let the battery totally discharge. So charge it before it completely dies.

oh really... but I already made my Note battery to 0% and shut off itself two times I also did charge on 40-50% to 100% bcoz I know I would have to stay outside without battery charge after. I wish I can get an extra battery in my country soon.

Your problem is probably not related to the battery but to some apparently draining all the juice. There is an app called something like betterbatterystats, not sure on the spelling though, it might help you to find those draining apps. It's been reported manytimes here in XDA.
And for your information it's better to charge when the battery dies for the first couples of times. I don't think that it makes a big difference after that.

U may also want to check the process or apps running on the background?
I freezes all the unwanted apps or process les one by one to try it. But in terms of the batt usage, I believe if u don't use it much often u can still stand by for at least a day. Mine running on full 3G, but screen brightness set to lowest and STILL facing some batt drain issue.

Charging from a total 0 is actually good and most technical people will suggest the same. In fact a full battery drain every month and then a full charge ensures your battery gets a full charge and a complete battery rotation. This is a good thing that you did and let no one tell you otherwise.
However, for normal usage the lower the better at which point you charge is best.
All of these batteries comes with xx full cycle charges - meaning how many times they will last from 0 to 100% before they degrade and start giving less efficiency (around 85% on future charges) after the full cycle charges are over.
You may want to use 10% as a good benchmark to ensure you dont lose an important call with your phone off. The battery saving mode on the Note will also help you reduce loads at times and improve battery life (at cost of system power).
Congratulations on using the Galaxy Note, which I feel is the best all in one device in the market!

I second this.. its funny how still people still believe those myths about batteries (like charge 100% before you use the device first time).. those issues are easy 5-10 years old.. batteries now a days a have smart chips built into them that can control the battery health

So, I can charge my battery anytime when needed?
Also, for screen brightness, i set auto brightness is better than setting it manually low?

Battery charging wear

Didn't find a main thread for silly questions such as this so hope it wasn't wrong for me to post this here, but I currently find myself in my phone going as low as 50% on a daily basis and I charge it next day at not lower then 40%, will this wear out the battery? am I really supposed to charge it when it's really low? Thanks.

The latest in Li-ion batteries, as the one in our phones, one duty cycle is when you use 100% of the charge.
That is ifyou go from 100 to 0 that's one cycle.
If you go from 100 to 50, recharge and again 100 to 50, that's one cycle.
Batteries wear out depending on the number of duty cycles. More duty cycles, more wear.
So what you are doing will not wear out the battery.
Also I'm not sure about this, but it is recommended that newer batteries should not be completely discharged.
Please correct me if I'm wrong, anyone else who can confirm.

Modern batteries are not like older (10 years+) batteries. I'm not about to write a wall of facts here etc. etc, but I only have one thing to tell you:
Use your device, and don't worry about the battery. It'll do just fine until the day you decide to buy a new device. Now stop worrying and just use it.

Same here, these batteries are tough. I am anal about my phone battery being charged. Haven't had an issue for years and I expect the same performance out of my S7E

Topping up your battery before it is fully discharged is the best way to extend your battery life. Modern batteries run best between 40%-80% charge. Minimize the number of times you fully discharge the battery as that is more likely to wear out the battery, although it is ok to use it until the phone shuts off once in a while.

Very impressed with the battery of the S7E. I charged to 100% last night and didn't charge until just an hr ago and was at 47%. Normal use in the morning til now. In n out of meeting, so its doing its job.
Now back to the topic of this thread, i've read some say these newer batteries should be power cycled at least once a month. Any one recommend that or against it? Haven't done it myself but did it a few times on my iPhone 6 Plus and that thing had an awesome battery even though its actually smaller than the S7E. Thoughts???

I've seen it recommended as often as once per month or as infrequently as once every 3 months. The general consensus is that it can be beneficial in that it can correct any issues that the phone software has in determining the battery's capacity, not that it is actually helping the battery itself.

Yup, I did that once in a while with my previous device (a Sony), and the battery on that one is still very good after nearly three years. I wouldn't do it that often though, but it's useful to do it when you notice the battery meter hangs on the lower numbers (like if 10% hangs for an unusually long time) or you've just flashed a ROM. The OS tends to get a little confused after some time, so it's okay to do it to "calibrate" the system again.

Thanks for the helpful replies guys.

Draining a Lithium battery to zero is one of the worst things you can to an Li battery. Don't do it. Period. Ever.

Yes, don't power cycle a battery. It MAY help give a more accurate battery reading, but it's messing up the longevity.

Mines been quite poor, but it's been downloading and installing apps over LTE for hours. Not exactly a fair benchmark.

7 hours of screen on time with 10 percent battery lef. I'm satisfied

Same here. But when i finished installing it, I fully charged it around 9pm last night and it just went to 10% today at 1pm

I'm at 4h 40m screen on time, with 36% left in the tank. I put the mid batt saver on at 65%. At this point I'm pretty impressed.

The battery is downright impressive!

Yea I don't know what happen but my last 2 charges after that has been around 5 hrs max. I didn't do anything different. But I'm still satisfied with 5 hrs SOT

One thing that isn't mentioned enough is battery maintenance and care. A carefully maintained battery will last longer, and store more energy, therefore providing more time between charges. I have a lot of knowledge about lithium based batteries in the hobby grade Radio control models. I have been maintaining lithium polymer and lithium ion cells for about a decade. So I would like to compile some tips for everyone.
1) Heat. Heat causes the most damage to lithium based batteries. Leaving your phone in direct sunlight, as most of us know can cause your device to catch fire, or even explode. Water is useless in extinguishing a lithium fire. Lithium cells will burn under water. This isn't new info to most of us, but I mention heat mainly for these reasons;
A) rapid charging causes increased heat in the cell. This increased heat degrades the cell, causing reduced cycle life. This is significantly more concerning on modern phones without removable or replaceable cells. Therefore you should avoid rapid charging unless it's absolutely necessary. Especially overnight. If your sleeping then there's no reason to rapid charge.
2) Voltages. Voltages are also very important, but since these are managed automatically you don't need to be overly concerned about them.
A) 3.0v this is the minimum voltage at which your charger will still recharge the cell. Most phones will shut off at 3.3v or 3.2v. This is your 0% charge level. The reason this is significant is that once your phone shuts down from a dead battery it is important to recharge it within a reasonable timeframe. It may take a week or 2 for the cell to drop those last few tenths of a volt, but once it does it's over.
That said, it is good to completely drain your battery occasionally because this helps the OS calibrate a more accurate battery charge percentage.
B) 4.2v is fully charged. This is your 100% charge level.
C) 3.7v is the best voltage for cell storage. This is approximately 50% charge. That is why your phone is usually about half charged when it is unboxed. (But who stores their phone lol)
So the important takeaway from all of this is, avoid rapid charging when you can, and once your phone dies, recharge it soon after. -Chris

Not bad. Got me through the day. ~4 hrs sot

Too early to tell. I had like 3.30 SOT. After a couple of charge cycles it's getting interesting.

I went through 16 hrs of my average use and had 39% battery left before calling it a day. That's at least 30% more than what I was squeezing out my Note 4 on 6.0.1. Idling overnight for 7 hrs the battery went down only 4%.
I'm really impressed so far!

People getting 6+ hours SOT, can you let us know what your setup is like? Are you disabling stuff? Running dark theme?

If the question is for me....yeah, Material Dark Theme. Nova Launcher, no stuff disabled (Wi-FI/Loc/BT etc.). No app power saving. Hi resolution. I run "Optimize" once in the Device Maintenance menu.
I'll post a stats screenshot at the end of the day

I don't really trust any battery benchmarks right now..... the phones are all brand new...... lets all wait about 12 months and re-check them; While compared to the Note 3 my Note 7 replaced I am generally happy with the upgrade to the Note 7, the sealed battery is really pissing me off. I was using the Zero Lemon 10,000 mah batteries on the Note 3. I can almost gamble that the battery in the Note 7 will be useless in 12-24 months depending on usage and then we are stuck with $800 bricks unless someone figures out how to safely open the phone so we can replace the battery on our own.

Yesterday I had 7.2 hours of SOT. First few days were a little less, due to initial geek out, setup, testing. Seems on par with the my Note 5 and S7e.
What this shows me, is that I need to spend much less time in front of a phone's display....

For how I use the phone, I can easily get over 7 hours SOT....with 10% or more left. Yeah... I disable all the Sammy/Tmo bloatware I can....as well as Lookout, Android Pay, Facebook stuff...and a few others. I always use Nova 3.3 (the last before they switched to the horrible white themes of LP & MM) and I've been using a minimal black theme from the Sammy store, that has the color rings around some icons. Love it. I don't use auto brightness...and normally have it about 30-40%. I also don't ever use NFC, so it's disabled. I rarely use bluetooth....and i don't do any gaming really. I imagine if you're doing those things...battery life will suffer a bit.
Though I definitely think it helps to have an all black theme going. Settings, dialer, app drawer....solid black. And don't have the screen too bright of course.

I don't know how good or bad it will be but in my opinnion it's going to be average and its a note so i'll be using the phone a lot. I just bought the wireless charging case from the T-Mobile store i work at My coral blue comes tomorrow !!!

S8+ & AccuBattery: What is your estimated capacity?

When the S8 & S8+ were released, Samsung made a fairly bold claim that users would have 95% battery capacity left after a year. Being a current Note 4 user looking to upgrade to either the S8+ or the Note 8, I'm curious whether this claim holds any truth.
Thankfully, there is a great tool called AccuBattery which lets users estimate their remaining battery capacity based on charging data from a few charge & discharge cycles.
If you already have AccuBattery installed, I would love to hear what your estimated capacity is. Please vote in the poll and leave a comment.
If you don't have AccuBattery already, I can really recommend it since it seems to be a fairly accurate way of calculating your battery's remaining capacity.

I have had accubattery installed since I purchased the phone in June.... Started at 103% and is now down to 100%.

Don't really understand how to read the numbers, but here are my results after ca 48h of use.

Mine is at 97% so that's good considering I've had my phone for 7 months now

The health section will give you the estimated capacity, but it needs a few charge & discharge cycles to work it out. In your screenshot it is still blank.

Yes that is pretty impressive! This is all making me feel less concerned about the battery being non-removable.

Mine is at 96% after three charge cycles using the app. The phone is one week old.
Kind of makes me wonder how accurate it is...

This could be due to slight variances in actual battery capacity or slight inaccuracy in AccuBattery's measurements. Hard to know.

After charging 125,972mah I still have 3466mah capacity left.
I do my best to keep the battery in the 30-80 range

It requires quite a few charging cycles to get an "accurate" measurement. I have found that if you keep the app open on the health page the estimated capacity goes up while you watch, so I take the measurements with a grain of salt.

After 5 months of usage.

Had mine since release date and I'm down to 92%. I'm tempted to make Samsung replace the battery tbh!

Impressive!

Haven't checked on my current S8+, but on my first one which I had from April to September, it was at 3430 mAh right before I sold it, which is 98%.

I'm at 88% after 6/7 months... I'm very disappointed about this... In one year my battery will be about 2800mah... If so will use the one year warranty on battery to have a new one...

My S8+ is now at 80% capacity. 8 months old and already lost 20% So much for Samsung’s claim of 5% degrade in a year.
Mine has quadrupled that claim in barley over half of a year

That doesn't sound right. I think Samsung will replace the battery for you if it goes below 80%.
How do you usually charge?

Guide: 8-10 hours SOT battery - restore battery health

Been reading dozen of threads on diffrent forums regarding people complaining about their poor battery health, performance, etc.
Here are my advices to obtain near 100% battery health as years passes by (I have an galaxy s3 from 2012 with 90% and an LG g3 dual sim from 2014 with 92% ???), it all has to do with user behavior:
1. Avoid not charging to at least 95% then discharging it to near 0% (example: you charge it from 0 to 50 then you go outside and discharge it to near 0)
2. Avoid high usage for more than 3 consecutive days.
3. Drain SLOWLY from 100 to 0 once a week. This drain must be done at least in 1,5 - 2 days.
4. Charge from 0 to 100 with phone off at least 1 time / week
5. Every 2 weeks Let the phone discharge in 2-3 days, with minimal use, like just calling.
6. Repeat nr. 3 as much as you can
7. Avoid putting to charge when the phone is hot.
8. Avoid charging while using the phone.
9. Avoid fast charging.
10. From 100 to 70 and from 30 to 10 go slowly.
11. Never let it discharged 5, 10, 20 % more than 1 day
12. Never charge from 20, 30 to 100.
And many more will come.
Cheers.

Well im barely getting around 4:30-5 hours sot without stamina mode BUT not gaming nor watching too much or heavy stuff so it sucks im gonna contact my local center to get it replaced and then ill take your advice

You don't need to replace your battery. Just follow these advices and it will recover capacity.

no i dont think so as it is physically wearing out (because I litterally tried to follow and install another guy's same apps and layout, disabled exactly same apps and ran exactly the same FW and his battery did a MUCH better job).

Dude, it's all about battery CAPACITY! You can restore it if you let the battery recover following my guide.
Batteries tend to loose capacity if abused, but also to recover the capacity. Remember that it does not have 1 year. There are batteries with 3 or 4 years usage and doing fine job.
If you follow my guide you will notice an increase în capacity after 1 week.

This advice about draining and charging seems to be similar to advice that used to make the rounds suggesting you should calibrate your battery. Actual calibrating of a battery isn't possible (and advice like this guy's was debunked long ago), but sometimes your OS will give you faulty readings. You could take a look at https://forum.xda-developers.com/android/general/guide-how-to-callibrate-battery-device-t3308554 to see if there's anything useful.
Beyond that, generic tips like https://www.androidpit.com/how-to-save-battery-life may be helpful. Or, you may just have a bad unit. It happens.
This is a quiet forum so you probably aren't going to get far posting multiple questions about whether your battery is any good. If you think it's way off normal, then perhaps you have a warranty issue, or maybe you have a local shop that does battery surgery with OEM units. Being that this is a sealed full glass body, I doubt anyone could replace the battery.

So, despite the fact that a lithium battery can't change capacity, and everyone from Google to good developers saying you can't change your battery's capacity, you're suggesting he can? You might be able to get the system to more accurately display the stats by following some full charge and discharge guidelines, but the suggestions you're making don't change battery capacity because they can't.
And yes, batteries most certainly do lose their ability to hold a charge over time, which is different than capacity.
