I notice the "tips" to use it to charge it to 95% MAX, and use it to no less than 5%. Are these claims true? I have no problems of re-charging it before the 5% mark, but to constantly keeping an eye on the phone while charging it can be tedious and annoying.
Anybody can shed some light my way regarding this subject?
Thank you!
Well, your anker lipo would feel better (and any other lithium polymer battery for that sake) if you would not do full cycle every time. Full cycle means you goes from full to empty charge/discharge. (95 down to 5% counts almost as a full cycle)
Say chemistry in lipo can make 200 full cycles before 20% capacity lost or 500 half cycles (like from 100 to 50% and then recharge to 100%). See the difference, longevity will be bit better with half-cycles.
If you store lipo for prolonged period of time (like month) then don't charge it to 100% but to 50%.
And don't keep your phone in high temp zones (like in a sun in the car) this will kill lipo in no time.
Other then that just enjoy your anker. It's cheap enough to replace it in 500 half-cycles (which might be translated to couple years)
Thanks for the response! From the way you describe it, it sounds very familiar with how my lipo batteries for my rc cars work.
I usually charge my phone at 30% mark to fully charge. So, given that, it'd be ok for me to charge it overnight (to 100% then trickle charge until morning), and let it discharge to 30 - 40% then recharge.
Phone will stop charging lipo when it reaches 4.2V so there is no problem to over-charge it... keep it on a charger overnight.
I do one full cycle about once in month but this is for different reason.
Usually, I can go from 100% at morning to 40% at evening in two days. Then recharge it overnight. I think my Anker 2200mAh will outlast my SGSII.

I have a 3900 mAh battery from Mugen. Ive noticed the battery lasts about 30 hours. But I find something very strange. It drains around 96% in just 15 minutes on straight boot after charging every time. In fact, the first 80% of so drains pretty quickly? Ive had it in my phone for about 2 weeks. Has anyone else noticed this or know why this may be happening. Also when at 100%, and i inplug it, goes straight to 98!
Have you done a battery calibration? Get the Battery Calibration app from the play store.
There's some argument as to whether this does anything or not, but have you conditioned the battery? That means letting it drain completely, then charging it continuously till it hits 100% - do that several times.
Its been proven that the app does nothing, which wipes battstats.ini or something
As for conditioning, its been down to around 3% before being charged. Ivehad the battery 2 weeks now.
Lithium Ion batteries have a very steep drain for about the first 15-20% and also slower charging from those levels. Once past that the drain is nearly linear, and then gets very steep at about 3.6v.
You can see it in the graphs here:
http://www.ibt-power.com/Battery_packs/Li_Ion/Lithium_ion_tech.html
Typically the way our devices are designed, they do not charge the battery to 100% full it can actually cause damage to lithium ion based batteries. what happens is the battery is charged to 95%-98% then the device stops the charge and allows the battery to drop to abut 85%-90% and then starts trickling it again. By design the batteris typically drain a little bit fast at the top level.
further more lithium ion batteries survive more recharge cycles if the D0D (depth of discharge) is about 25% remaining.
Basically you battery will last longer by the device not charging to 100% and letting it discharge slightly when in trickle mode, and if you don't let it die completely and charge it when it reaches around 15%-20% left.

Hmm that kind of makes sense. Everyones been telling me to not let it drop to below 35% though cause it 'wears the battery out'. Ive been charging at around 40 cause thats where itd be after a full day at work and such.
Ive been getting concerned though because ive seen screenshots of people getting 31 hours with 7 hours of screen on time.
Im at 62%, 9.5 hours total, 1 hour 7 min screen on. Thats mostly with Wifi on though.
My stock battery used to drop 10% an hour on 4g, and this one dropped ~11% on 4g just now....

Thanks for the graph!
Sent from my amazing G2x running EaglesBlood and Faux.
Now at 36% And its just sitting off mostly with some light texting
Now 35!
Got a weird feeling the battery is messed up.
Its 3900mah, divide by 650 = 6 hour charge
Its been 6 hours and its at 46% with the phone off so its not using power, and on the wall charger.

The maximal battery life for LiIon can be accomplished like they do with Hybrid/Electric cars. If you cycle from 80% to 40% you will get 10x the battery life (equivalent total Ah used) compared to charge and discharge from 100% to 10%. In fact, leaving a LiIon battery around the 100% to 90% range or under 10% permanently reduces capacity (it's chemistry)
If you have root, is there a script or app to stop charging at 80%? I suppose the batteries are not quite laptop expensive, so I guess for $30 you can just buy a new battery when you go through the 500 full cycles.
i just got the phone yesterday (att) i charged the first time in 4hours , is that okay cause people told me that i needed to charge in +8 hours ,and now do i have to use the phone to die completely and charge it again or just need to low battery ? sr for my bad English

here is the answer for your question:
Lithium-Ion - Li-ion batteries are the newer type of battery that are found it most newer cell phones (most definitely most, if not all, smartphones use Li-ion and many "dumbphones" use them too now). Li-ion can be thought of as "smarter" than NiCad batteries; Li-ion batteries don't suffer from the "memory effect" and thus don't need to be conditioned like NiCad batteries.
Rather, to condition a new Li-ion battery, fully charge it; it should be allowed to charge for 7-8 hours on the first, initial charge. In other words, when you get your new cell phone - and it has a Li-ion battery - allow it to charge for 7-8 hours even if the cell phone claims to be fully charged. (It is preferable to use outlet charger vs car charger or USB charging via computer because of the voltage difference.) After that, there is no reconditioning necessary for Li-ion batteries since they don't suffer from the "memory effect". However, be sure to avoid fully draining/discharging the Li-ion battery as much as possible; every time a Li-ion battery is fully discharged, it loses battery power and life. (That doesn't mean your battery will die if it is ever fully discharged; it means it is best to avoid fully discharging when possible.) Try to recharge Li-ion batteries when they are at 15-25%. Similarly, avoid heat as much as possible and when (if) storing Li-ion batteries, store them not at full charge.
Update: The only time you should ever intentionally fully discharge a Li-ion battery is if your phone is not properly reading the battery. In other words, if you go from 100% -> 90% in ten minutes but go from 90% -> 80% in one hour with the same amount of usage, that means your phone is not reading the battery output evenly. If this is the case, then fully discharging your battery once and then recharging it can fix the issue of your phone not reading the battery properly. Take note, however, this full discharge/recharge won't increase your battery life -- it will only ensure your phone reads the battery properly.
People often confuse Li-ion and NiCad batteries and try to condition Li-ion batteries by charging/discharging them 4-6 times. Trying to condition a Li-ion battery like it is a NiCad battery (i.e. charging/discharging the Li-ion battery 4-6 times) hurts the Li-ion battery more than helps it. So, be sure to condition your new cell phone's battery, but be sure to condition it properly. Otherwise, you may be doing more harm than good. If you are not sure what type of battery you have, read the labels on the battery - they will always say whether the battery is Lithium-ion or Nickel-cadmium. Good luck and may we all have long lasting batteries.
p.s. i got my one x yesterday too and is most beatiful phone in the world
So I've been running some random tests with my battery and usage to try and figure out how this thing maintains charge and such. I'm running rooted stock TW 4.1.1 with Juice Defender.
1. Usually, I charge the phone overnight while I sleep, then when I unplug it, it drops down to 99% immediately. Lately, it's been dropping down to around 96% in 45 minutes of no use then leveling off. This is with a new battery that replaced another one right after the Jellybean upgrade as I thought my battery was busted.
2. I usually get about 12-14 hours with 2.5-3hrs of screen time (I get crappy service where I work and the phone is in airplane mode when not in use, and when in use, it has bad service).
3. This weekend, I didn't charge it over Friday night and let it die Saturday morning. Then I charged it for about 3 hours or so and ended up getting about 34ish hours with 3.5 hours of screen time out of it (using wifi and better network since I'm at home).
4. I charged it overnight last night (about 9 hours) and when I unplugged it, it dropped to 98 immediately, then 30 minutes later it was down to 96 again.
With all that said, I'm thinking that I probably should not be charging my phone overnight at all anymore. The only problem with that is that I don't have enough time in the morning to charge it before work and I can't charge it while at work as I move around all day.
Will I wear my battery down more by not fully charging it and using it throughout the day and only charging it when I can? I've read that battery website that people post constantly where they talk about how the new batteries stop charging after a certain period of time, but if that were the case, why would I get better battery service from only charging for 3 hours then leaving it overnight?
I know there are a million battery threads on here and we probably didn't need another one, but i thought I'd try to create one with a bit more substance than "oh i get 6 hours with 5 hours screen time on such and such a ROM". I'm more interested in the physical methods than the software methods for getting the best out of the battery.
The quick drop off in battery charge is probably partly due to some hysteresis that has already built up. There is a lag time between the voltage demand on the battery and the battery's ability to deliver the required current. Energy is lost during this lag time.
I posted this another forum so I am recycling but it is relevant.
Some general guidelines when charging Li-ion batteries:
A slow charge is preferable because it reduces heat and hysteresis. Heat of any sort decreases the overall life of the battery. Hysteresis reduces the performance of the battery in the discharge state causing a quicker plummet in battery charge from 100%. (NiMH batteries are worse with hysteresis, but Li-ion cells suffer from hysteresis also).
Unplug the charger as soon as possible when the battery is fully charged.
Lithium ion cells however can not tolerate overcharging or overvoltage and the charge should be terminated immediately when the upper voltage limit is reached.

Do not use charging pads or mats as they introduce more heat.
Pulse chargers do the best job because they give the battery brief rest periods to allow the chemicals to settle and accept the charge with reduced hysteresis and heat.
A memorable though not quite equivalent phenomenon is the pouring of beer into a glass. Pouring very quickly results in a lot of froth and a small amount of beer at the bottom of the glass. Pouring slowly down the side of the glass or alternatively letting the beer settle till the froth disperses and then topping up allows the glass to be filled completely.

Depth of discharge. Consistently letting the battery run down to very low reduces the overall lifetime. It is better to minimize the depth of discharge by topping off when convenient than running it down completely.
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while.

gotcha. so i shouldn't be charging it overnight anymore. thanks for all that other info, too. very useful to know.
Hey its been a few days since ive received my one plus 5t. Wanted to know what are the typical charging cycles you guys use. Do you guys charge when battery is below 5 and stop at 100? or something different.
i am aiming to use this phone for about 3+ years so would be great to know how can i maximize my usage in this duration.

you can charge your device pretty much at any time just don't let it drain to 0% (shut off condition) as that'll theoretically deteriorate the battery in the long run. I had a wrong perception that charging the phone from 0-100 and discharging back to 100-0 will make the battery last a little longer ( tried it with my moto e and moto g which eventually started giving me random shutdowns at 20-25% juice left) which is totally opposite of what you should do. With the 5t I usually put it on charge around 15 and then straight to 100 or around 70 when I'm in a rush.
I typically charge when the battery is around 20 - 30% and I have an app to stop charging when 60% is reached. According to Battery University it's best to keep between 30% to 60% but of course practicality has to come first. 60% upper limit has worked pretty well for me as I can usually charge my phone when needed.

There are two factors killing a battery: heat and voltage. A lot of heat (over 30°C) will degrade the lifespan of your battery.
High and low voltage can degrade it too. The optimal voltage would be around 4.05 V. Anything higher degrades it and anything far too low (under 3.5 V or so) can even make it non operational without a high current "boost" to make it usable again. However, lithium batteries tend to charge to 4.4 V which is good for battery life but bad for the lifespan.
In short you should not keep your phone at 100 % over a long period of time and never discharge it completely. Heat and voltage induced by fast charging is also bad (faster charging means higher voltages of a few 100 mV).
I'm using Magisk and the Magic Charging Switch module to charge it to 90 % and only charge it at 80 % again. At night I lover it to 80 % and 70 % and 45 minutes before I wake up it is charged to 100 % making the battery only use the max voltage for 1 to 2 hours instead of the whole night.
Leaving the phone plugged in wouldn't hurt it im terms of cycles etc. but the constant high voltage does hurt. More information can be found here. Really worth a read: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
