Hi guys,
I'm writing because I have noticed that my battery performance change if I use a regular 2A charger.
With Pixel stock charger, which implements fast charge, sometimes battery drain is fast after stopped charging. For example, from 90% to 85% in a ten minutes.
With a regular 2A - 5V charger, the discharge is more regular, and I have also noticed that the battery life is better. The problem is that it takes a lot of time.
Has anyone noticed the same?

I've notice many ppl discuss about their aftermarket battery were unable to
reach 100% when using standalone aftermarket charger.
Just to point out that the S3's battery is using 4.35v cell instead of the usual 4.2v cell.
Most standard charger stops at 4.2v thus they'll stop at around 90%.
If you're looking for standalone charger. Best to look for charger rated at 4.35v.
(I rooted and change kernel to undervolt the CPU. the result is excellent, anyone who want longer run time should do it)
Every charger is 5 volts. The phone sets the charge voltage, not the charger, which is 5 volts.
The OP is referring to the voltage of the battery cells, not the USB charger (which is always 5V). The battery on the GS3 is in fact a higher voltage than most other phones (like the GS2). If you use an offline/standalone battery charger that does not charge to the full voltage of the GS3 battery the battery will show about 90% charged when you place it in the phone.
i wrote a review a few days ago on a stand alone charger i bought.
so far no problems with it charging my battery to 100%.

Is seems logical on the surface. Will fast charging mean discharge will also be faster?
Did you ever use a 'non quick'/ normal charge adapter? Did you find that the battery charge lasted longer?
At night I use a normal charger. The fast charger I use only when the battery is low and I'm in a hurry.
I did not notice any difference in discharge time.
The phone discharges fast when using it heavily (gps, games and browsing with FF), but still gets me through the day. With light usage (messaging, calls, email, little browsing) I have like 50% battery left after 12 hours.

i don't think that is the case. discharging based on battery, charging based on charger circuitry. of course both contact must withstand the high current pass through before breakdown. ( if you want to know more, read up on current and its effect on materials, size, width)
Someone did a charge log before on ze551ml on the full charge and each software module, hardware drain comparison, he found out that even though written 100% on the phone, the actual charge did not hit 3k Mah. seem like our lipo battery is not really 3k worth therefore you see a fast draining effect from 100% down to somewhere 80~90ish?
this is true on my side, i know some apps is not coded for optimization and efficiency, for this can be felt by handset being warm because heat is a form of wastage (losses) in engineering term. however some apps that does run optimised also exhibit fast draining effect.
more testing need to conduct in order to conclude that guy's theory.
Atleast I experienced faster discharging in case of fast charging as compared to normal charging.
I have not experienced fast discharging while using the BoostMaster Quick Charger. What you should take a look at are your battery stats, Screen on Time, usage scenarios and signal. Check wakelocks too as that can damper your battery life throughout the day.
After using Turbocharging in Moto X Style i can confirm that fast charging will result in faster discharging, also the battery heats up while turbocharging, and i noticed 20% less standby time (at least 20%) when i use turbocharger. If i am not in a hurry i always use overnight charger.
What is the optimal way to charge the OP3 in order to preserve the battery lifetime? I don't care about charging speed, I just want the battery to last long with minimal degradation. Is dash charging bad for the lifetime of the battery? Or would I be better off charging the OP3 slowly with a traditional charger? Right now I have this charger

You should be using the OnePlus charger and cable which came with the phone. For optimal battery life, don't let the phone discharge below 10% and charge it till around 90%.
Dash Charging should be comparable with QuickCharge 3.0 which helps preserve battery life. So I reckon the official charger is your best bet.
Charging a battery with high intensity is bad for a battery life, dash charging/VOOC or quickcharge (any version) will be bad for battery in the long run.
But you'll only see a difference in 3 or 4 years and I don't think you'll use your phone more than 3 years. And even if you want to keep it more than 3 years, even if you don't use the phone, age will act on the battery. Even if you charge it slowly or quickly, there won't be a big difference in 2 years. Just be aware that USB-C cable have an active component in the cable head and a cheap USB-C cable can dammage your device.
If you still want to charge OP3 in good way, you have to plug it on a computer so it will charge at 5V 0.5A. It's very slow but it should charge your phone overnight and during the day, charge it while you have any occasion. 10 charge from 70% to 80% have less impact on the battery than 1 full charge from 0% to 100%.
Don't run it flat, keep it above 20-30% and don't fully charge it.
Don't leave it on charge overnight.
I run mine from about 30% to 90% maybe a little over as a 90% charge is what it takes to reset the days battery stats, screen on time etc.
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.

Older USB chargers are mostly slow 1A chargers, like the cube Apple chargers

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 charge my phone every 48h and when it is full I unplug it from wall charger. And I charge it from 20-25% (some time I go lower because of my usage)
It's your famous amazon wall charger?

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.
I had my battery replaced and bought THIS wireless charging adapter and THIS wireless charger and I'm noticing my battery drains faster if the phone is charged wirelessly. For example: when charged with cable my screen on time would be ~ 1 h at 90%. When charged wirelessly screen on time would be 20-30 minutes at 90%. All in all the battery drains noticeably faster. Should I replace the adapter or charging pad?
