As Samsung declare, to extend battery life of your gear S, never recharge more than 80%!
I don't know why, but a Samsung engeneer teach me that this trick works perfectly on all devices, in SAM laptop, for example, user can choice this function from BIOS!
So charge until 80% and get out more than the original 100%??

Basically this trick is not to make the battery have a longer period before it drains to 0% but rather to make its entire lifespan longer. It's the same thing with draining if to zero. Ideally, lipo batteries would be kept at their nominal voltage (40-50% on most batteries) in order for them to have the longest life.
Hope that helps.
Thank you for the tip!

I normally follow these tricks on increase the battery life of Android devices
Adjust the brightness
The display on your watch doesn’t always have to be super bright, especially if you’re indoors most of the time. There are usually five or six levels of brightness depending on the Android Wear watch model, and the default is usually a setting of 4. A setting of 3 is a happy medium, but you can probably get away with a level of 2 most of the time.
Turn off Tilt to Wake Screen
Tilt to Wake will automatically wake your watch when you hold up your arm and tilt it towards you. A very useful feature, but you might find that your display actually turns on a lot of times when you never intended to look at it. This might seem harmless, but it adds up over time and will lower your battery life.
Block unnecessary notifications
Getting notified about new emails, reminders, the weather, and other important stuff are crucial to your experience with Android Wear, but there might be notifications that aren’t as significant. Blocking those that aren’t will reduce the amount of time your watch wakes up.
I normally don't let the battery runs under the 20% of charge for smartphone and smartwatch too....

That's not a batter management tip - its a tip for the Samsung designers to get a clue and improve the detection algorithm. This is a problem on many Samsung devices I have hard - they bungle the face, motion and light detection algorithm, so the phone is always slow to detect you when you do need it, yet there are far to many false detections.

Good morning all,
I know we all try to get the most out of our battery in our phones, and it seems to be an ongoing struggle and brought up alot. I'm just curious how everyone measures their battery life. Do you go by total running time? Screen on time? Awake time? Another method?
Personally I tend to go by how much screen on time I get. Obviously it should be able to make it through the day as well. But at the end of my day if i'm trying to see if my battery is holding up as i'd like, i usually check how much screen on time i had throughout the day. I find that generally if i'm at about %25/hour of screen on time I'm Satisfied. (usually get about 4-4.5 hrs in a 14-16 hr day).
Obviously there is no perfect method (ie you'll get less screen on time if you spend alot of time streaming with screen off, playing games, etc). But i'm just curious as to how most judge whether or not their battery is holding up to their expectations.
Thanks!
Really long ruler.
The moment you start using your phone, there are too many variables that are going to change. There are also few optimizations you can do - screen fundamentally uses a lot of battery for example.
The key is to reduce baseline idle drain as low as possible - saving your battery for when you use the phone.
So when I'm hunting power management regressions or running tests, I focus on baseline idle drain. The method I use is sort-of covered in my Known Battery Drainers thread - charge to full, reboot on charger, remove charger after boot complete, reset timers in CPUSpy, let the phone sit overnight.
My definitely for "my battery life" is the amount of time between charges, aka. using time.
"Using time" does not mean time that I physically use it but the total time when it unplugged and ON (ready to use).
I guess each individual person has their own usage, some use more than others. I posted the "Battery Usage" image so that gurus can verify it "ok, it's typical" or "that's ok, it's normal for that much of usage" or "nah, something wrong, it's a defective"
Sorry, I just couldn't resist...
Screen on time plus phone calls and music time. Also gotta factor in the radios that were on (GPS, wifi)

I am really starting to loose my patience with the prime, I have had it for a week now and its just been a very a difficult ride so far. Coming from the original iPad, I never had any problem with it. For some reason, I lost 20% of my battery just surfing the web last night, now I did not view any videos, I was just reading several online newpapers. 20% in an hour !!! what the hell is going on here.
Can sombody recommend me a decent battery monitoring app pleaase? otherwise, this thing is going back and then I will have to beg Apple to take me back.
How many things do you have syncing? Cutting down on that saved me a lot of drain. Also the app you use depends on what you're looking for.
Where's my Droid power seems quite useless on the prime
Better battery stats is good for finding apps with wakelocks
Current widget is good for tracking the current your tablet was using but I'm not sure if it works on he prime
Good luck!

What brightness was your screen set to? Did you have SuperIPS turned on? 20% seems excessive but having the brightness cranked up can noticeably impact battery life, and using SuperIPS nearly triples the drain.
FWIW I keep my screen brightness to about 30% most of the time and I surf the web for about an hour or two a day and I have been getting 3-4 days of battery life or more. I leave the tablet turned on all the time as well, and last night after 3 days I plugged it in because the battery had finally reached 50%.

My Battery Drain Analyzer is good if you want to see an ongoing indication of how much battery is being drained per hour. https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain&feature=search_result
However, in order to characterize your battery use as good or bad, we'd need to know the brightness you were at (as others have mentioned), whether you're running Flash on the sites you were visiting, what performance mode you have the Prime running in, etc. Too many variables.
I'll add that it's difficult to compare an iOS device and an Android device in terms of battery use, because the Android device is likely doing much more in the background. There's a tradeoff between functionality and battery life (and between functionality and simplicity, etc.), and of course in such an equation Apple ALWAYS opts for reduced functionality. That's not necessarily a bad thing, but it's definitely Apple's approach and has to be factored into any comparison.
I do burn about 15%/hour when browsing, on 30% brightness or so and in Balanced performance mode. I've found the Prime to be excellent in battery use everywhere BUT browsing--video about 10%/hour, email/ebook reading/etc. bout 7.5%/hour, etc.
Thank you all for your comments. My brightness level is set to 20% and gps, bluetooth all set to off. I am now using auto airplane mode app and it has significantly improved the battery life. I am also now using a fantastic app called android assistant and i spotted services that were running like google+ and google voice search which were consuming a significant portion from my battery.

The best battery monitoring tool I've found is Battery Monitor Widgit.
And I would highly recommend Tasker over any app that is dedicated to turning a single function on or off. If, that is, you are willing to learn to set it up. You can do things like have it set screen brightness to max when you start YouTube and set it back down to your preferred setting when you exit YouTube, turn WiFi or GPS on or off based on certain criteria, etc, etc, etc.
A simple free alternative to Tasker that I use is AutomateIt. The most rules are set on my phone to turn antennas on/off and manipulate volumes while I'm at work, driving, or at the gym. If you're looking to do more complex thing, Tasker is probably the better alternative.

Thanks for the tip about Android Assistant. It seems very useful!
However I would get rid of Auto Airplane mode, you don't need it.
Instead go into "Settings > Wifi > Advanced (top right menu)" and change the "Keep WiFi on when asleep" setting to "only when plugged-in (recommended)" or "never."
What this does is that any time the screen is off, but you are not currently downloading a file or app, the WiFi will be suspended until you turn the screen back on.
You can turn GPS off from the settings if you never plan on using it, and it doesn't make sense having an extra app running in the background that just duplicates functionality already found in the OS.
Hope posting here does not violate any of XDA forums rules.
I have an idea for a while and I need your opinion about it, and therefore if anyone wants to help...
There are too many apps, solutions etc. for power saving. However, most of them create a bigger consumption problem or limit the phone experience. We also know that about 20-40% is consumed by screen brightness, especially when it is above 30%. Auto-brighness is a solution but not the optimum because in many cases it is not the desired one. Not to mention that many devs state that auto-brightness should be avoided because it could be power-consuming as well. Finally, it becomes obvious from the battery menu in settings that the line declines sharply when we have the screen turned on for a LOT OF TIME. Cpu processing does not even seem to consume as much as the screen (when not processing in full).
So, noticing that the screen can become power hungry in relation to how much time it is turned of, then the variable that adjusts the brightness could be the time.
What I mean: Most of our essential actions, like reading a message, make a call, change a song or even search something in internet take about 30 seconds to 2-3 minutes and require a relatively high brightness at any case. Other actions such as internet browsing, gaming, reading etc take more than 4 minutes up to 20 or what ever.
So, I was thinking to apply a minimum and a maximum limit in brightness. For the first actions like reading a message the brightness can start at the higher limit and stay there for as long as this short-time action takes place. For the second group of actions the brightness could start from the higher limit and after 3 or 4 minutes the brightness to start decrease at why not an exponential rate until it reaches it lower limit.
Advantages:
1)You set high and low limits so you are never dissatisfied with what the device gives you
2)Not quick and sudden brightness chances as it happens in auto-brightness.
3)Always high brightness for short-term actions
4)Great energy saving from long-term actions, like gaming
What do you thing? Is it worth give it a try? i would have tried it but I do not know how to make a script for it. Also many ideas for it and mods that I can share if you think it is worth spending some time.
Sounds alright, but the deal breaker for me would be seeing the screen slowly get darker before my eyes..

Exactly, that's the point. For example during the 2 first minutes the brightness to stay as high as the upper limit and then after the two minutes to start GRADUALLY getting darker up to the lower limit. So you can start at 80% which is pretty convenient to check the time outdoors with sun and then if you browse in internet it can start gradually getting darker until it reaches the 65%. If you could see the graph the area is significant amount of energy. If only I could make a script I would try it or at least make t happen for myself....
Overall I like the phone, but I have a few gripes. Maybe some of you agree, and maybe some of you know some solutions.
Much better than the Xperia z3v I had at first. The Xperia had a few odd things about it that bugged me, and the lack of root was getting to me. That is what made me switch.
But it did have much better battery life... I would have 50 to 60 percent battery when I returned home, the G3 will be below 20 percent most days.
The keyboard has a one handed mode, but its prediction and correction are not good. I somehow miss the space key and get run on words all the time, it's been a little frustrating. I know of no third party apps that have a one hand mode though.
The auto brightness is better than the Xperia but still not as good as it can be, it requires too much attention. It limits it's range and trays to be adjustable but it doesn't work well.
Its size has put it over my comfortable one handed use size. The one handed mode helps a bit though. Can't really do much about that. It seems to be the trend.
Its close to being a great phone but held back a bit. Maybe there are solutions to most of my woes.

Battery life for me is great. You might want to get Wakelock detector and see what is causing this. I can get 36 hours and still have 40% left. Also, it just depends on what you are doing with it. I send/receive text messages, make phone calls, surf the web, read news, etc. Usually, I have it charged before I go to bed and when I wake up 7 hours later, it's still at 100%. I leave it on all night as I use the phone as my alarm clock.
Now, I am rooted and I use Greenify to help hibernate a lot of apps. However, you don't have to be rooted to Greenify now. I don't hibernate any system apps and I don't sync a lot of unnecessary stuff either. I also have the Snapdragon Battery Guru app installed which works well. However, I will say, for a few days, I didn't root this phone, didn't use Greenify and used only the Snapdragon Battery Guru and I was still getting well over 24 hours of battery life.
I use Swiftkey and it has a one-handed/compact layout. It seems to be doing fine for me, but I don't use one-handed mode.
I feel you. Whenever I do any type of graphics intensive gaming (i.e. Real Racing 3) during the day, battery drain is crazy. When I don't use it as much, Ive had the phone go for two days. The phone seems to have great conservation when the screen is off, but that massive high-res screen has got to have something to do with battery drain. It's not the most convenient, but personally, I've found the best solution to be a quick mid-day charge. Phonearena did a charge comparison between phones, and the G3 is one of the fastest charging phones on the market right now. 2 hours for a full charge. Like I said, it's not the greatest thing to have to plug in your phone during the day, but I've found that even a solid half an hour charge makes a huge difference.

Well, yeah. Games are going to drain it no matter what and it depends on how long you play. I've noticed even with Game of War, an hour of gaming will drain it maybe 8% or more. Just depends on what you do with it.
Any phone is going to drain like crazy, but yes, the Quad HD display definitely drains the battery more due to the higher number of pixels. But, for those with every day normal use (not gaming), this phone definitely lasts more than a day.
Whenever I play a game, if I'm at home, I plug it in if I know I'm playing for a long period of time. otherwise, if I'm away from home, I know I can still play over an hour of a game and still have plenty of juice to last me the rest of the day.
I would rather have better battery than the added resolution screen. 1080p is very good for a phone.
I watch youtube and mess around online a bit on breaks. Same behavior as the z3v and dramatic difference in battery life.
I never found one handed mode in SwiftKey.
Nvm... Found it
The screen is the biggest user of battery... 60% according to the battery use chart.
These past few devices I have had... Has lead me to a conclusion.
All this undervolting and CPU throttling is pretty much useless.
The processor in this device and my last few, has had very little load on it for the most part. Some games may push the system, but general use and some youtube barely has the device going more than a couple steps above minimum clock speed.
Background services and sync... Small effects overall on battery.
It's all about that screen and it's power efficiency. Resolution has something to do with it as well. As the GPU must run harder on higher resolutions.
Turn down the brightness... And then I can't see the video I am watching.
An android phone with a current SoC, a 3000mah battery, a 4.7-5 inch screen, and 1080p resolution... Should be able to get well over 10 hours of screen on time, running video...
The radios are power hungry as well, but mostly in prolonged use like video streaming.
This size and resolution war has prevented us from gaining what we want most... Great battery life.
Still the phone ain't too bad.

True with that. This isn't an 1080p resolution screen. It's more since it's a QuadHD, so that is definitely what kills it. But, I don't watch videos for 10 hours! LOL. But, I know what you're driving at.
With credit to VR-25 from Github:
If you edit these files and put you own values in then your phone will start charging when it drops below 75% and stop when it gets to 80%. (put your own values in, etc.)
I have only tested it briefly but it seems to work for AC and USB charging for me so far. No other apps or tweaks needed.

EDIT: You need to be rooted to do this, and you need to reapply the settings after reboot.
I have a Tasker action that does this automatically 5 minutes after rebooting.
If only there was a way to use that without root :-S
What would be the purpose for this.
I always charged to a 100% and never had issues on my devices.
I use the adaptive charging overnight and think that will help with battery life.

If you do some reading you will see that charging over 80% and draining under 20% will significantly shorten the lifespan of your battery. This is important for those of us that have devices not sold in our country so getting replacement batteries would be very difficult and expensive. I have phones that are more than 9 years old and still going fine if charged like this.

On the contrary. The most recent phones attempt to limit the time that they spend at 100% exactly because it's so bad for battery longevity. Having options like the OP's approach just gives users more flexibility, should they want more control than, in this case, Google's adaptive/AI approach.
And it's not 'wasting' 40% of the battery. Keeping between 80% and 20% just optimizes battery service life during those days you only actually only need 60% of it's possible capacity. When working from home that's often the case for me. I actually tend to use ~30% of the battery in a day. Better to charge it up daily to about 70% than all the way to 100% and let it go down to 10% over 3 days. If it's easy to do, why not?
Not quite the same, but EV design also has their batteries normally operating in the middle range so as not to compromise their service life...
Definitely not myth. The only myth is that lithium cells exhibit a memory effect and need to be deep discharged and fully recharged periodically to maintain their capacity. It's actually bad for them to do this! The only reason to do this would be in an attempt to recalibrate the software for the battery level gauge (at the cost of a little damage to the battery each time you do that).

Most folk don't notice reduction in battery capacity until it becomes severe. For example, a friend claimed it wasn't a problem charging his iPhone to 100% ritually. When he checked the OS, it said his battery capacity was 80% of what it was when new. He said he hadn't noticed it affect how long the phone lasted.
If your usage is such that you can predict how much capacity you need, you can choose to charge to 100% only those times you will actually need that capacity. Other times you can look after the battery so it's able to actually give near on 100% for longer, those times it's important to you.
Others who keep their phones a short time or are comfortable with the cost & inconvenience of a battery replacement, or simply don't care, don't have to worry....

This all maybe good if you are planning on keeping your device for a few years.
Most people buy a new device every other year. If not once a year.
... and if you really want to knacker the battery, heat it up too!
Worst case scenario - using a sat nav app on your phone in the car on a hot day with the phone plugged into a car adaptor. It's going to be sitting there at elevated temperatures, possibly with the sun shining on it, whilst being kept at 100% battery....
I'm only a customer (and have no other affiliation) and like to tinker, so I got one of these for use in the car to limit temperature when charging and limit max charge. Not cheap, but ok compared with the cost of the phone https://chargie.org/
I'm sorry, but at the snails pace this phone charges I'd be very surprised if charging it to 100% every night will make any noticeable difference in the long run. I had a Xiaomi Mi10 Ultra with 120W fast charger. That phone used to charge from 0% to full in like 20 minutes. Now that's one way to quickly kill your battery.
The Pixel uses your alarm to adaptively charge the battery so it should never overcharge it anyway. I'd much rather us all of my battery than use it only between 20 and 80% just for it to last a little longer.
The files are overwritten on reboot so I created a Tasker task to write the values on reboot each time.

On what basis? All the research and tests are based on charge level not charge rate. Fast charging potentially just makes it worse...
But at the end of the day it's your phone. You'll charge it in whatever way works for you.
I feel like this post sort of misses the point. It clearly is aimed at those intending to keep their phones >1yr, it is stated explicitly.
I'm not rooted right now, so I've been using the AccuBattery app. One of the things it does it gives a notification every few minutes when the battery is at 80% or above so that you can physically unplug the phone from the charger. Obviously having this done automatically would be better, but I've been surprised at how well the notifications have worked in my case. Plus, I can always leave the phone plugged in if I know I need a full battery for some reason (ie a long day away from any charging source).

If you edit these files and put you own values in then your phone will start charging when it drops below 75% and stop when it gets to 80%. (put your own values in, etc.)
I have only tested it briefly but it seems to work for AC and USB charging for me so far. No other apps or tweaks needed.

Dumb question but what did you use to write values into those files? Did you use a text editor (with root access) or just termux or something? I tried with the built in MiX text editor but it seems to choke once I open up the file.

I used FX File Explorer (root option). Look for the #. SYSTEM (Root).
I was wondering if changing the file permissions after writing to them to read-only would make the changes stick, but I am sure the OS could still overwrite them...??
I wonder if there's a similar variable to tweak at what temperature the phone considers the battery is too hot and stops charging?

Did a bit of testing and it works fine. A few things I noticed:
1. Doesn't survive reboot. Now that I've set up MiX with pinned folders, I can make the change in seconds. Need to sit down and read through the acc documentation because AccA doesn't work. Would love to have an automatic solution. Miss my old Battery Charge Limit.
2. charge_start doesn't seem to matter. After all, if charge_start is set to 75 and the phone is at 70%, it shouldn't charge. But it does. I've kept mine at 0.
3. Point #2 is kinda beside the point, though, because charge_stop will stop at the set value and stay there. No noticeable increase in temperature from what I can see. Definitely less than when charging.
4. Still shows as charging rapidly when it hits the level. Is it rapidly cycling charging on and off? Or in a kind of micro-current state? Or this may be a true battery idle situation where all power is drawn from the adapter. Ampere and AccA just show "not charging".
Edit: With a bit of use today, it does seem to act like a normal min/max charge deal, so I set it at 75 start/76 stop. Not sure what was happening at first...maybe something to do with the adaptive charging since I still have that on. Either, way, no complaints. With my use case working from home, I have it plugged in most of the day and it'll only take me about a minute to change charge_stop to 100 when I'm planning to go out all day somewhere away from chargers. Not ideal, but still a big improvement. Changes my rating of the thing from maybe 3.5 stars to 4.5.
