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

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.

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.
Curious to know if somebody could share me regarding slow charging after 90%. Actually OP3 dash charging is damn awesome but after 90% or specially after 95% charging becomes too slow. Between I m in 3.5.5 community build. Any explanation or solution would be great.
not just oneplus but pretty much every manufacturer does this possibly to avoid battery damage. You are not supposed to charge batteries over 80% and below 40-50%, it gives your battery the longest life cycle however its something extremely hard to manage.
normal behaviour while charging.
charging above 80% is not really damaging the battery but its wearing them down little faster as it would when the level is kept between 20 to 80% (just what i heard from others)
i usually charge mine to ~ 90ish and unplug the phone
on average i get through a day with less than 60%
It's completely normal (and desired, like already pointed out). First few and last few percent are slower than mid-levels.
It still only takes a bit over an hour to charge from 0 to 100. And it's still the fastest charging device on market.
I'd say that's damn good enough ?

This is optimal for battery life, due to how lithium batteries work.
Do any of you experience that after 95% it seems to take way longer to charge that last 5% than getting to 95%?
Actually, the last 20% should be slower than initial 80% due to the battery being Li-ion and fast charging technology. You can have a quick search on google and see for yourself.
Specifically the Z Play I have, charging up to 80% is warmer and faster than the last 20%.
It is also suggested by a lot of people that you should only charge your device to 80% to maintain that battery for the longest time possible. I still charge my phone all the way tho.
It's how Lithium battery charging works, first it's constant current CC and then constant voltage CV. Once the battery voltage reaches a certain value (4.2V or more depending on the Lithium battery type), the charge current decreases every time the battery voltage tries to go over this preset max voltage. The charge current gradually decreases and when it reaches a certain value (usually 0.2-0.3A) the charge stops.
Awesome. Makes sense. I was just wondering. Good stuff!

It will charge device fast till 76 percent after that it charges slowly.
You had also noticed that phone get warms up a little during charging till the battery percentage reach to 76 percent.
Ok guys,
SOT was just around 5h 30 min so I suppose battery is pretty badly worn out.
Probably the phone has been used around 1.5 y and I see date of manfufacture 09/2019.
So I switched to dark mode,enabled power saving,disabled all gestures,switched to fullHD+ res and for sake of battery I'm nor charging with super fast option.
I think I won't even charge at max capacity because accubattery tells me the wear out has smallest value when I charge it at 85 %,so I suppose I will charge it to 85 %.
I will discharge battery at 15 %,never less.
I'm charging with airplane mode ON,because I'm not busy person to need phone while charging.
I can also charge the battery when the phone is OFF and I suppose that is good for battery too.
So dear friends what else I can disable in Android 11 and try to increase it's lifespan?
These are all things which came to my mind from experience.
Phoneinfo is reporting under USAGE HISTORY when I tap on it few times health of only 41 %,but don't think it's accurate.
With other software DevCheck and AccuBattery can't get battery wear level,discharge cycles info.
Now I charged it for first time after buying phone to 80 % (suggested by Accubattery) and this is what I got,dunno if it's accurate or not,but I don't believe that health is 96 %,I wish it is.
Don't discharge past 20% but 30 or 40% is a better cutoff. Charging to 70 or 80% max most times will also help. Li's prefer frequent midrange charging.
These batteries aren't that hard to change out. Just had one fail in my Note 10+. As they age that becomes more likely to happen.
Keep an eye open for rear cover bulging, replace the battery asap if this happens.
The battery sits directly on top of the display and can damage it if it swells.
Erratic fast charging and diminished capacity are also signs of a Li battery failure and with the hump there's no doubt.

oh okay,thank you.
Look at the accubattery readings,doesn't look that bad,huh?
How and when will I know that battery is for replacement?
I still can't find software which would report me wear cycles.
Accubattery... this is it's least useful feature.
Compare your SOT now to when it was new.
It's way more than a 4% drop in capacity.
In reality it's more like 60% or so! It depends of course on how much it's current draw is now and if it's about what it's usage was when new*.
It may also be the phone as it maybe incapable of actual ma measurement and only estimates it bases on battery voltage drop.
*my 10+ is getting around 10 hours SOT but with some battery hogs it could easily fall to 6 hrs SOT with a new battery.

Great deal. You did good, the 10+ is a great phone
It still running on Pie?
The SOT runtime is very subjective depending how well optimized it is. If it's running warm* while surfing the web with screen brightness at 40%, it's not optimized and probably using more battery than it has too.
*ambient temp around 72°F but the phone is noticeably warm.

Great app for getting most of of your battery with some great performance tweaks as well. Difference is very noticeable on my device and premium is very reasonable.
Also recommend tasker. I have it set so my NFC and mobile data are automatically of when at home and automatically turned on (with WiFi off) when WiFi disconnects. Also GPS off at all times unless Google maps is open. These made all made a huge difference for me. Reckon combined they at least doubled my battery life per charge.
