Got the phone in december. Never had 5k mAh. From the day one it was about 4.6k mAh. Measured with AccuBattery app, and by measuring charge time. Both not 100% accurate, but supports each other.
Charger output is 1.5A, so it should charge from 0 to 100% in no less than 3hr 20m, but givven that charging slow down above 80% or so, it should be even slower. I don't remember exact charge time of mine phone, but it's somwhere around 2h 50m.
Althogh it still covers all my needs, it's still a little bit dissapointing.
What is your phone real battery capacity?

If you don't mind using a custom rom, you can try any custom & get rapidly charge (even with the stock charger). I'm using latest aex 6.5 it has cherry kernel out of the box since the maintainer is the same (aex & cherry kernel). Check the attached pic.
No,the capacity of the battery is 5K
Your doubt is valid that 1.5A of charging should charge in so and so amount of time,but the charging speed even on stock rom soars to about 1.8A depending on device temperature. This is the reason why the phone charges well within the time calculated by you

Even if my charging time versus 1.5Amp statement is unrelaible, then the ampermeter in the phone is also shows wrong info. Because AccuBattery calculates capacity based on charging current Ampers * charging time. So, if internal ampermetter is lying, your could lie about 1.8Amp too.

Just bought a 3500 mah battery. I heard if charged with the evo it will only charge it to 1500 mah. Is that true? If so do I have to charge out externally or is there another way?
Sent from my htc evo 4g. ALL HAIL EVO 3D!!!
No, not true at all. At first, yes, because it's used to the 1500 mAh stock battery, but it will start being fully used after a few charging cycles. Just give it time, and it'll be fine.
You don't need anything extra.
You can also wipe battery stats to make the process a little quicker.
I can verify what JustRuin wrote - I actually gathered data from Current Widget and Bat Stat, and compiled them into a spreadsheet (hey, I was bored at work, and it beats calling customers). What I found is that the phone will display that it's full in terms of percentage, once it's charged to what would be 1500 mAh based on the percentage it's showing when you start charging. For example, if you're showing 33 %, that would be 500 mAh out of 1,500 mAh for the stock charger. If you then charge it at a net charging current of, say, 1,000 mA, the light will turn green and the phone will show 100% in about an hour. but the voltage will still be down around 3.9v, and the net charging current will continue at the same level until the voltage reaches around 4.2 volts. On the stock battery, the charging current will start dropping after you reach 60%, and by the time you're around 90%, it will barely be charging at all. On the 3500 mAh battery, charging current stays consistent until you're around 4.15 -4.2v. If you simply leave it on the charger for a couple hours longer, you'll have a full charge and no problems with battery life.

so what your saying is that even tho the light is green, the phone will still be charging?
Yep, it's definitely charging.
This is why i dont use sbc. I went a whole day without charging. From 7:30am to just about 15 mins a.go and i still had 50 percent left on my battery. simply just unplugging it and plugging it back in before i take my shower in the morning and i stay at 100% for about 2 hours.
Hey guys. Within a minute or so after my phones removed from the charger it drops to 95%.is this normal?im using the 1.8a LG charger that comes with the phone F240L.i read somewhere that they are using the LG charger 1.2a out of the box.does this phone have two different out of the box charger..thanks..
Completly normal. The method that seems to be employed for the battery percentage is read the voltage itself and make a guess
This high voltage drops down quite quickly both as a "load" is applied to the battery,. Plus there is not a lot of change in capacity from the very high voltages to the more normal voltages, in any li-ion battery. So while the voltage can be used to guestimate a range of charge levels, between like 4.0 and 4.3 there isnt much changed in the battery itself.
Further from what i have seen so far (not totally sure) they are charging to 4.35v which is a rescent slight change in the chemistry of the li-ion to allow for higher charge levels without it gassing or reducing the life (Havent tested that theory long enough yet either).
Also All li-ion alogrythms for charging do a CC CV charge, where the final charge is just "holding" the voltage at the high, till the batterys charge state floats up to that level. This can (not facted out yet) mean that leaving it on the charge past the time it claims it is fully charged , it will put tiny bits more into it. This happens more with my big fat zerolemon battery because it seems to have more resistance to the other connected cell items than would be desired.
Anyways all is well, just dont believe anything a computer tells you , and it will be fine The other methods have thier own deficiencies.
Other STUFF:
Li-Ion batteries really do not prefer to be left at their high charge voltages, as they degrade faster there. so when you read the above, or try "bump" charging methods (thats just restarting the charge) It is not good for it. The battery will be happier, using it like it was designed, taking it off the charge when it states it is full. all of this being more info than anyone needs to know, or freaking care about.
As a li-ion battery becomes old and weak, it will exhibit even more of these charateristics that have people wondering. It will drop off the highs quicker still, have less total capacity, and increse a tiny bit in resistance , which will cause it to drop even more under load. At some point the battery would be so bad at that, you would want to replace it.
Heat, the li-ion cells dont like these extreeme heats. they prefer to work more at normal room temps and cold but not extreeme cold. So take that in also as a factor in keeping your battery more happy, again if you want to waste half your life pampering the thing

It's the calibration. Happens to me too sometime. Drops rather fast to 95%, then goes stable around 89%. Just leave it on charge for an extra 45 minutes or so, then let the battery die down to at-least 10% before charging again. Not exact science, it's just what I do.
I purchased my 5t about 4 weeks ago and the stats in AccuBattery are now showing my capacity at 2930 mah and the health at 89%. If accurate, these are somewhat concerning considering how new the phone is. Anyone else seeing similar stats? I ran AccuBattery on my Nexus 6p and it always seems pretty accurate.
That's the same capacity I get on my phone with AccuBattery. Other people on the OnePlus forums also had the same results so I think that it is probably normal.
I don't trust that application any more (even if I bought it 2 days ago). So i purchased my phone 4 days ago and after the second charge it says 89%.... Many battery applications are useless on the Play Store.
It is a little wonky on certain phones sometimes. Have you done several charge and discharge cycles? I know it definitely won't be too accurate until you run it a few times. Since you said you used it on your 6P though, I'm guessing you know this already. As long as battery life is still good, I guess I wouldn't worry too much.
I run Accubattery on my mine, it says 92% after a couple of weeks. Battery lasts for a full day of heavy use, and then some.
I also ran it on my 2 year old Moto X Style, and it said 51% - and I felt it was telling the truth, since I got about 2hrs SOT from it if i was lucky!
Same for me, showing about ~3000 mAh from the beginning.
It's also showing ~107% on a Nokia 3 of a friend of mine, so I guess you just can't trust the app on that perspective.
lol, guys
ok now, several factors to consider before you jump to conclusions (ive been using accubattery for several months now with great results):
1) your sample size is waaay too small. every scientist/engineer/mathematician, etc out there will tell you that u cant jump to a conclusion based on just two samples. give it some time, use the app regularly for several weeks and only THEN can you make assumptions about the accuracy of the collected data.
2) ive noticed that the final capacity reading is more accurate, the closer a charge cycle is to 100%. which makes sense if you think about current quick charging technologies: they provide high amperage at steady voltage at first up to like 75-85%, then they switch more and more to trickle charge with low amperage. advantages: fill up the battery quickly, but without putting too much wear onto it.
thus: if you just do a quick charge cycle, say from 30-50% then the slope steepness is way higher, thus the calculated capacity will differ. so there is a dilemma: either do large charging cycles with higher wear on the battery, but more accurate capacity data in the end, or do smaller charging cycles with inaccurate data but less wear on the battery.
3) when charging to 100%, dont unplug the phone when it reads 100%! rather check the current charging amperage in accubattery. only when that drops to zero (or -1 mA in my case) is the battery fully charged and ull get a more accurate capacity reading than when stopping the charge when 100% is reached. if you unplug it too early, the capacity calculation will be on the low side
hope this helps!
cheers

Yup, am scientist, can confirm
Same thing happened to me, even after using AccuBattery for a couple of weeks (and thus collecting more than a couple of samples, both Dash charge and "normal") it still showed 89% battery health at around 2940 mAh. Got my phone one month ago.
I don't think there's any problem with the battery itself, especially as it's not just me having this problem.
Maybe the battery is 3000mah and they are lying about it ???

I'd say 30% of the times 10 to 100%
40% of the times 30/40 to 100%
And the rest just random stuff: 50 to 100, some top ups here and there
This is not scientific data though, that's just what I recall from the couple of weeks I used AccuBattery. I'll try to find a screenshot but I doubt I have any.
I reinstalled it today and from a single 14 to 80% charge it gave me ~2930 mAh and 89% health. I'm on OOS 5.0.2 stable, will try the app for some time and share my results (more scientific this time)
After several weeks of use, the reading is still constant at 86% ~ 2827mAh. Not sure what to think. As previously mentioned the first 5t I purchased and returned for the 128gb version came in at 89% same as @Explyy. Is it possible I have an inferior battery?
hm, there indeed seems to be a pattern emerging with so many different users reporting identical capacity values at 2900-3000 mAh for their new op 5t. two possibilities: either accubattery cannot properly read out and analyze the 5t's battery charge controller. or the battery capacity is indeed around 2900-3000 mAh instead of the advertized 3300. its normal for battery capacities to be around -100 mAh from the official value, but -300 to -400 would be crazy.
guys, just to be sure: did you leave your phones plugged in until the charging rate in accubattery dropped to 0 mA? as i said before, if you unplug the phone once it shows 100% but still charging, the resulting capacity will be less than the actual one.

Yes, I left the phone plugged until the charging current dropped to 0, as I noticed that when it reaches 100 it's still charging at a few mA
On a related note I charged my battery from 10% to 100%, until the mA rate dropped to 0mA. I had the phone hooked up to a USB power meter during this time. The USB meter only read about 2500mAh charged. So since I only charged 90% of the battery I figured it should be around 90% the capacity of the battery, which is 2,970mAh. If I assume the battery is 3000mAh then a 90% charge would be around 2700mAh, closer to my reading. I'm going to run some more charge cycles and see if I get the same results.
Edit: forgot to say that I used a standard 2amp charger, not the dash charger that came with the phone.

Someone who's having accubattery report ~3000 mah should download AIDA64 and look and see what it reports the battery size to be......
So I bought myself a decent USB multimeter (RuiDeng UM25C) because I was curious about my Mi 6 battery capacity after 20 months of everyday heavy usage.
I was avoiding charging to 100% all this time (max to 70%), only charging to full once a month maybe and never using a phone during charging. I also rarely discharged to less than 30%. The full charge counter in /sys/class/power_supply/bms/cycle_count is showing 642 full accumulated charge cycles, so quite a lot.
USB meter showed 14300 mWh after a full charge 0-100% (which is 110% of the original capacity 12900 mWh, impossible). So I did a search and found an article saying that Quick Charge 3.0 has around 90% charging efficiency.
So I made a quick mathematics and calculated that the battery should have taken in 14300 mAh x 90% = 12870 mAh (the rest of energy dissipated as a heat), which is basically new battery's capacity (which is again quite improbable, even with my special battery treating ).
My question is: is this calculation wrong? And if it is totally wrong - what should I count in additionally to get the more proper mWh estimation?
Thanks for any help
Hello guys,
To offert at my battery the best treatment I'm looking for a lower amperage wall charger for my Pixel 2XL.
Between 1 and 1.5 Amp it will be excellent. I read some interesting suties about battery life and how manage it and fast charge is part of that.
Thank you all anf have good evening.
I am sure it will charge on either one, but how fast who knows? If you are rooted and have Magisk, download the ACC module and you can control your charging that way instead.

I am an electrical engineer, and have some knowledge about how Li batteries function.
I have always wondered this, I always see people mentioning that slower charging is better for the longevity of Li-ion batteries. There is always a trade-off here. Slower charging also means the battery takes much longer to charge, and the battery stays hotter for longer period of time, which should affect it's lifetime. Fast charging also does the same thing, but the temperature is much hotter but is exposed for shorter period of time.
Now these is merely a speculation on my part, I don't have any theoretical or experimental evidence to back this up - I think regular 5V 2A charging is a balance between those two scenarios.
Also, I recall that the peak charging current is limited in P2XL, so using the stock charger shouldn't harm that much either.
Pixel 2XL is my first smartphone who do not Come hot when it charge so...
But I know that high temperature are not the best things for battery in general.
And about the level of charge ? Some people said they stop at 80% to manage battery

I use a 5 watts charger and the phone stay completely cold during the charge process.
Also there was a recent 2017 scientific paper that tested what degraded the battery. It's a really interesting read with many tested model.
https://www.researchgate.net/profil...e-model-under-different-charging-stresses.pdf
Number 1 cause is high battery voltage at the end, second one is battery charging speed. Any speed faster than 1c will degrade the battery much faster.
This is why i charge at 5w plus stop charging at 80% (unless i know I'll need 100% that day, where i fully charge, but for my usage 80% is more than enough for the usual day).

I download AccuBattery and charge my phone from 25% to 80% max. The app detect directly the stock capacity of my battery (3520mAh) but after my charge, the new capacity estimated is 2982%. Is the first value is reliable or I have to do some other charges?
You have to wait for about 10 cycles. It says in the application something like that.
