One of the things I have noticed scouring the internet for tips on battery life prolongation, is that you end up with lots of contradictory advice coming from unreferenced (and often, unresearched) sources. (Note that by 'prolonging', I mean both prolonging the current battery cycle, and also, how to prolong the battery in the long term).
One big question is how you should be recharging it. For example:
Do you let the battery go down low, and then recharge it back to full?
Do you only do partial discharges, and always keep the battery topped up?
When available, is it better to work plugged in?
There are two helpful articles, both from the Battery University, which seems reliable and they have nice experimental data.
[1] Charging lithium batteries
[2] How to prolong lithium batteries
From what I gather, the answer to the above questions are as follows:
Full discharges will reduce the number of recharge cycles in your battery. For example, going to 100% discharge only gives a battery with 500 discharges, while going to 10% discharge gives a battery with 4700 discharges. Note that this advice contradicts other 'unreferenced' sources, like here:
Change your charging pattern: Most of us have the habit of charging the phone quite often even when the phone has enough battery left on it. It’s always better to leave the battery to discharge completely to say like 20% and only then recharge it. This way your battery will not only also last longer but also has longer life.

It is better to note recharge to full
Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery. Choosing a lower voltage threshold, or eliminating the saturation charge altogether, prolongs battery life but this reduces the runtime. Since the consumer market promotes maximum runtime, these chargers go for maximum capacity rather than extended service life.

However, I admit that this is a fairly PITA rule to implement. It would be impractical to always charge only to, say 80%. I think this rule, in practice, advises against charging all the way to 100% because then your charger may put in the topping charge (how many chargers do this?)
It is better to not leave devices plugged into wall charges.
Some portable devices sit in a charge cradle in the on position. The current drawn through the device is called the parasitic load and can distort the charge cycle. Battery manufacturers advise against parasitic load because it induces mini-cycles. The battery is continuously being discharged to 4.20V/cell and then charged by the device. The stress level on the battery is especially high because the cycles occur at the 4.20V/cell threshold.

A portable device must be turned off during charge.
This allows the battery to reach the set threshold voltage unhindered, and enables terminating charge on low current. A parasitic load confuses the charger by depressing the battery voltage and preventing the current in the saturation stage to drop low. A battery may be fully charged, but the prevailing conditions prompt a continued charge. This causes undue battery stress and compromises safety.

This, however, spawns two further questions:
What about USB charging? Because USB charging is slower (due to a lower amperage), is there any advantage to working with your tablet plugged into a USB drive? Is this better than discharging the battery?
I work with my laptop plugged in all the time. Partly, there is nothing I can do about it (Macbooks no longer allow easy removable of the battery). This means that on top of the heat degrading the battery, one must contend with the battery contunually being charged. What are the safeguards in place? I would imagine a smart charging system would lower the voltage and amperage when a laptop is plugged in.
I remember when I used a iPhone that one cycle includes partial charges and discharges like if you charge 10% and then another 20% and so on you ad those until you get 100% of a cycle, this was according to apple. That's why you can get your battery dead in one year and half (since they promises 450ish battery cycles )

Hey, thanks for this, man. Good tips. I don't want to go abusing the batteries of all those shiny new Christmas gadgets.
Thanks very useful tips
Yes for li-ion you never want it to fully discharge.
Rift
I like the research you did here very nice. I have an EVO and that thing can't hold a charge for anything. I have like three batteries (two that come with wall chargers) just so I know I'm not going to run out of juice when I need it. I could leave everything off like mobile data, wifi, etc but then why do I have a fancy smancy phone then to begin with I want to use the damn thing. The battery is my only real issue I have with this magnificent phone. Thanks for taking the time to do some research on the subject.
Thanks for the tips. Battery is important than CPU now as for UX is concerned.
battery management
i found the battery manager from Market Place really useful for my I9000 Galaxy S on ICS
thanks for the good information
Thanks for this news
If your worried about power "cleanliness" you could always get a power conditioner to guarantee level output.
Now with batteries being able to be replaced easy enough (droid user) and with in my price point I don't give it too much thought.
Thanks for the great info, should be a big help
Glad I have insurance.... battery dies, they give me a new one!-
3G or 2G
Had someone checked, if using 2G instead of 3G giving the much better battery life?
If you are asking if you get more battery life with 2G than 3G, I think it's the same. The battery life should be less if you have the option "use 2G/3G preferred" because the phone searches simultaneously for 2G and 3G frequencies
Now that you bring that up, has anybody compared 3g to 4G battery life?
Thanks for the tips. It really does get confusing when coming to batteries.
Thank you for the advice
i agree...and have found this all true in my own studys and doings
When I use programs that read battery stats, like GSam or Battery Monitor Widget, both of them says that when my battery is full (100%), the voltage is at 4330-4336 mV, which afaik is too much for a Li-ion battery.
My friend with a Galaxy S4 said that when he was charging his phone (was at 70% at the time), the sensor was reading 4313 mV.
But when he got to 100% it dropped to 4266 mV.
Is my battery really at 4.3V or the android sensor is a little off?
Despite the fact that two times already when my phone was below 50% it shutdown overnight (there's a thread here that many others are having something similar), I don't know if my battery is crazy or just the android.

mine reads around the same mV when fully charged so think yours is normal,my battery dropped down too 50% or less a couple of times but never actually shut down.
im running back on jellybean now as i prefer it and the battery is perfect but that could be just coincidence.
I have tried asking Motorola customer care for the care . No answer yet from them . Have a similar post here . I think Motorola uses some different kind of battery technology with higher voltages . But yet to recieve any solid reply on the same . Meanwhile I think my battery's peak voltage has gone down from 4.325 to 4.29 and as a result I am experiencing battery drop from 100% to 80% quite rapidly especially with usage .
I know for a fact that Li-Ion Batteries will last longer if kept charged under their full capacity.
I tried to find a 3rd party app for this but all I can find are "battery extenders"...
I read that Galaxy S could do it, would it be possible for falcon ?
I wouldn't mind charging 90% of max capacity since I never go below 40%. It is healthier to keep your battery between 40 and 80% charge all the time to reduce unwanted reactions that degrade the Li-Ion compound.
You have no option except to manually unplug the charger when it reaches 90%.
There is no way a device can resist the current flowing into it through the same port it accepts the current, AFAIK.
Sent from my XT1033 using XDA Premium 4 mobile app
I dont think theres any app that can do that. What i recommend is that use a battery app that alerts you when you reach a certain percentage.
dewd!
Why the hell you think that you'll ever notice a difference in battery life span if you actually really only charge it to 90%? That's as much as true as it being wrong. You should start reading real books made of paper instead of reading the internetz-for-randoms, srsly.
Look it that way, your battery life span in dependant way more on how the battery is drained/charged, than to how much of its capacity in being recharged.You need to use that very same battery for at least 10 years to actually see a difference in life span, due to charging it to 90% instead of 100%....... and then again, you'll need a vast sample of batteries in lab conditions to even be able to tell if the difference is actually caused by this or that.
Use your battery as a normal user, it will last you probably more than you'll actually will own your moto g.
Also the phone charging circuitry limits the current to ~200mA/h after the battery is charged up to 90%.

Few days ago I received an extended battery for the Note 4 from MPJ.
The size of the battery is x2.5-x3 bigger than the original Samsung one.
It holds up to 6440mah and the packages comes with an extra back cover for your Note 4.
As we can see from the picture above the design is user friendly and the colours match exactly as they should match. Overall the design is not boring and it is eye catching.
Now the back cover has a gloss finish and it is also thicker and taller so the battery can fit correctly.
It does add an extra bulk to your device but from my perspective I don’t think it’s that much noticeable. Note 4 is already a big phone adding some extra height won’t be a problem, but yes it doesn’t look as good as with the original back cover. I had zero problems in everyday use with that back cover, not even with pockets.
Now let’s start talking about the battery life and how it performs!
Day 1 :
The battery life was just how I expected! As we saw earlier the battery has 6440mah which means 2x3220mah which is the capacity of your Note 4 original battery. With the OEM battery you can get 6 hours of Screen On Time (SOT) in 16-18 hours of total use. With this extended battery I managed to get 12 hours of SOT from the very first day! How awesome is that ? The pictures below talk by them selves.
Day 2 :
I have charged my phone through the AC. The battery life was awful! Only 7:30 hours of SOT, which can be achieved from the original battery also. I think my AC in that specific room is a little bit faulty that’s why the battery drained out so quickly.
GameBench :
I ran also GameBench to test out how many hours the battery can hold up playing Traffic Racer. I have played for 15 minutes and i lost 3% of battery juice. GameBench claims that the phone can last 6.5 hours playing this game from a full charge.
Day 3 :
I have recharged the battery from 7% to 100% from a power bank and I am at 62% at the moment with 4 hours of SOT and 10 hours of total use. That means the battery is doing better than Day 2.
In total i got 11 hours of SOT and 1 day and 4 hours of total use, which is great! I managed to get 2days with a single charge check out the screenshots below
The battery charges quite fast, i managed to charge it from 8% to 100% in 2 hours and 5 minutes.
Conclusion :
Pros :
- Battery performs great, it can last 2 days with medium to heavy use and can reach up to 12 hours of SOT
- In very light use it can last up to 3 days. (It drains 2% every 8 hours on idle with WiFi on)
- Full Idle can last up to 5 days (I believe even more)
- Beautiful Design and Colors match perfectly
- Feels great in the hand
- The extra bulk is NOT a problem
- You can buy it either with NFC or without
- The cutouts for the speaker,S Pen, Camera are perfectly aligned in the correct position
- It does add some kind of protection
Cons :
- The back cover has a gloss finish, it would be much better if it had a leather texture like the Original Cover
- Charging on AC is very slow compared to Power Bank
- The battery without the back cover can fell off , its not tight enough.
Overall its a great battery, having 12 hours of SOT is amazing.
The extra bulk was no problem for me instead the phone is heavier and it feels more solid.
I recommend this battery to everyone that uses their Note 4 heavily. People who think that 6 hours of SOT is not enough should get this battery.The only downside is the back cover, I wish it could have a more premium feel although I will continue to use this battery on daily basis

NOTE : When restarting the phone you get some extra juice between (10-30%) , that happens because the phone can read up to 3220mah and it gets confused with that extra battery power.

I do appreciate your review but that particular statement is not true at all because when you run the battery sensor display codes display stats and battery tests results are clearly denoted in voltage which is the key component in determining the battery life in percentage, not just in phones but world wide industrial and domestic battery applications. There's no way it reads in mAh. I studied battery technologies and applications in campus and in all our test runs about batteries the voltage was the key component in determining battery % never the mAh capacity which also varies infinitely because of the apparent resistance the circuit in it will give. Therefore you cannot use a infinitely varying component to determine a definite component.. NOT POSSIBLE! Voltage is still used to date in all battery run applications as the key determining factor in battery life. Just study how the intelligent battery charger works and you will see it clearly for yourself, that in the note 4 the 9v fast charge is actually the bulk phase in charging the battery, then comes the absorption stage and finally float which both require the 5v charge to complete these two processes that follow. So effectively not requiring the 9v all the way through and dropping to the regular 5v which effectively charges the battery very very well to within 90-95% of it's theoretical capacity. There's no way the phone reads in mAh because the A in mAh is totally load dependent as I have pointed it out previously.
The process you are observing there is taking place exclusively in the battery and is designated as the Redox reaction that when a battery suddenly is unloaded with a load requiring a significant current to run, the process of providing electrons still continues but because it doesn't discharge through the load (as it has been removed), electrons now build up at the cathode so that when the phone now turns ON, it finds a higher potential difference between the anode and the cathode which in turn the phone reads as a higher voltage hence translates that to higher % battery life.
Proof: leave any set of discharged batteries lying around for a while then come later and measure their voltage, tell me whether the voltage that you left them with is the same as it reads now. That is proof of the Redox reaction in ALL batteries.

Not entirely true. While not all devices will use current sensing for measuring consumption of power, voltage alone is not an accurate reading of a lithium battery's state of charge. The discharge curve between 3.7V nominal and 3.4 is the bulk of the battery's capacity. Yes it may be 4.2V at full charge, but as soon as you put a load that will quickly drop to 4V, even 3.9V depending on screen brightness or total current draw (heavy CPU activity, etc). It will then remain at that nominal voltage level (roughly 3.7V) through 60% or more of the battery's capacity. Voltage drop under load can be used, but you still need to know what that load is. If I have read correctly, phones that do not have current sensing capabilities have a "table" that outlines what parameters will equate to what mA current draw. IE: 75% screen brightness with 20% CPU load is about equal to 450mA current draw (pulling those figures out of my a** here, not factual)
I couldn't find the exact picture I was looking for, but here is an example of lithium based batteries' discharge graphs. Granted these are under constant load scenarios, but the point is made. Voltage alone is not an accurate reading of a lithium (whatever, ion, FE, cobalt, etc) battery. I know these aren't lithium ion batteries so the voltage levels are different, but the graph looks very similar, just different voltages. Again all these graphs are all under a constant load scenario, something our phones do NOT have the privelage of doing. Current load is always changing, from screen brightness, cellular/GPS radios, CPU/GPU activity, etc.
The Redox reaction is only applicable in a no load scenario. Discharge a 1S 1000mah battery at 1 Amp for 30 minutes. Let's assume everything is perfect, you will have consumed 500mah of power, and voltage will probably be about 3.5V under load, and 3.7 under rest. Let it sit (at the same temperature it was under load, say 35C), and come back a little later. Yes voltage may have climbed to 3.8V but as soon as you put a load it will quickly drop.
I'm not fully educated on how phones determine state of charge, but I'm guessing it is more software based on a combination of voltage level, and ASSUMED current draw based on those "tables" I mentioned above. Some phones do actually have current sensing built in. I think some of my older HTC phones would actually give you mA current draw, and could log mAH consumption.
"Smart charging" or whatever you want to call it is merely limiting current once cell voltage reaches 4.2V. This is why the last 20% of a charge takes longer than the first 80%. If voltage rises, current drops. Don't see the correlation to that in terms of measuring a discharge capacity.
Temperature also plays a large role in a lithium's voltage level. I'm an avid R/C guy, flying helicopters mainly. We use large 6 Cell 5000mah lithium polymer batteries with 35C discharge capabilities. If you were to charge your battery in the garage in the winter, and the cells were all balanced at 4.2V per cell after charging. You bring that battery inside to a toasty house that voltge could climb to 4.25 or 4.3/cell. Not a good thing but it allowed you to squeeze a little more capacity into your battery for that extra 10 seconds of flying. Granted our motors are pulling upwards of 10Kw (yes, 10,000 watts or more) so I'm sure it was negligible, but still it made you feel like you were getting more. Getting off topic here, sorry.
http://www.mpoweruk.com/soc.htm
Problems can occur with some cell chemistries however, particularly Lithium which exhibits only a very small change in voltage over most of the charge/discharge cycle. The following graph shows the discharge curve for a high capacity Lithium-ion cell. This is ideal for the battery application in that the cell voltage does not fall appreciably as the cell is discharged, but for the same reason, the actual cell voltage is not a good measure of the SOC of the cell.

Only downside is not being able to find a diztronic style "case" for it any longer. Just a slim rubber case similar to the diztronic that I love so much.

Received my MPJ Battery today, unfortunately the case doesn't close on all 4 sides. No matter how I do it, either the left side or the right side won't snap shut. Hopefully the replacement works better. Can't wait to see how much SOT I can get though. Had an extended battery with my Note 2 and loved it.

You have a good expo because as you say not all phones use precise mechanisms to determine battery charge but for a flagship model like the Note 4 we can't afford that kind of mediocrity. I was only addressing the part where the battery seems to acquire charge after a reboot which temporalily actually occurs due to the temp no load situation.
After reading all of the comments i decided and ordered the battery. Can anyone inform me, when the battery arrives, do i use it until it drains and charge for 8-10 hours ? or do i put on charge immediately and after 8-10 hours use it ?

Hello everyone
I installed a few apps to monitor battery performance because I noticed battery life changing, and noticed that the voltage output changed during the day. I started monitoring the voltage when the battery was about %35 till it reached %10. Voltage read by apps was about 3.7. But after recharging the phone and unplugging it, voltage was between 3.88v - 4.14v.
I'm now at %88 so idk if it will drop further or not, but generally speaking, is it normal (and healthy) for output voltage to exceed 3.8?
Thanks in advance
Android LG phone running 5.0.1. phone operating normally as far as I know. Tested different apps same readings

I'm now at %88 so idk if it will drop further or not, but generally speaking, is it normal (and healthy) for output voltage to exceed 3.8?
Thanks in advance
Android LG phone running 5.0.1. phone operating normally as far as I know. Tested different apps same readings

It depends on change voltage output on your battery for example when i am 26% at 3.3v when it's charging and to the 100% my voltage peek down 2.5v and will stop flowing my battery to prevent to overcharge that's why our phones can leave overnight because lithium battery are hi-tech and can stop a flowing.
unlike nickel battery or alkaline battery is doesn't record the data, doesn't have board inside for protection circuit, lithium battery can so.
calibrate your battery.
don't trust any monitor app will false your information if you are rooted then you can see all information about your battery.
And what your lg model.
