Hello everyone. I have this phone for a week right now and I'm really impressed how brilliant it is! I love it. But there are some questions I want to ask you and one of it is:
What is your average charging time from ~0% to absolutely full 100%? In my case it's about 3 or even 4 hours of constant charging. Even when on 100%, my widget (Battery life by Curve fish) doesn't show it's fully charged - still I have to leave my phone connected and after 30/40 minutes it says "full" and I can disconnect it. It's pretty strange because the charger is meant to have 1,5A output which is VERY BIG current in comparison with Xperia PLAY's charger (850mA). And many reviews of this phone say that the full charging cycle takes about 1h 30min from 0 to 100... What do you think?

Are you using it while charging 3-4 hours, if you are using it, it's charged and discharged at the same time?
But from what I know - thermal throttling is the cause again. Especially if you're using it.
Maybe it charges 1,5Ah for the first 15 - 30 minutes, but then the current goes down, because of the temperature.
Somewhere between 80-100% it is normal, that it takes longer. The charging current is as low as high is the battery charging state.
I put my phone to charge around 8 or 9 pm. Just unplugged around 3am and its at 97%.I used oem charger. That should be more than enough time to fully charge. What could cause this? Oem battery as well.
???
I've noticed that it backs off it's charging speed for the last 5% or so. I have a hardware dongle that measures current passing through USB cable ( powerpractical.com ) which confirms that it's drawing much less current when in the 90+% range. I suspect this is being done intentionally to reduce wear on the battery.

The first time I got the phone, I used up the battery. Then I recharged it for only 2 and a half hour to get from 1% to 100%. There might be some problem with your phone. Did you notice any apps used during that time? Probably because something kept the screen on during charging.....
Hm, yeah, my phone charged fully within ~3 hrs from 40% today (though the charging rate does slow dramatically at the end, falling from 5W (according to hardware meter) with 1400 ma charge rate reported in software, to 3W and 900ma at 90% and 2W and 450ma after 95%
I remember seeing the last few percent take a lot longer than that in the past, and coming back after many hours of charging to see it at 98%, rather than 100%. Strange.
i got 1 g920t lastweek
it's work very well include the charge and Battery
fast charge very good, cost 20 mins to charge from 5% to 60%
But when i take 80% battery, its very slow
put in charge for 5-6 hours and only get 2-3% battery
anyone have solution?
The charging current slows down as the battery percentage goes up, and drops down as low as 900 ma around 90%. I am not saying it shouldn't slow down, but it changes a lot in a small amount of time. My old moto g6 fast charged only up to 75%, and then would slow down. But here the charge keeps going up and down. Is it healthy for the battery?
Fast charging is not suitable for charging the battery from 0 to 100%, it's better when you charge phone for 15-20 min.
How long it is supposed to take to fully charge it with 25W charger?
Are the first times you charge it slower to reach full charge?
The time will vary. Battery capacity, discharge state at start of charge and the battery temperature throughout the charge cycle.
Charging from 0-100% stresses the battery (especially with fast charging) and shouldn't be commonly practiced.
Battery start charge temperature should be at least 72F, 82F is ideal. Cool it if it exceeds 99F while charging. Charging is a electrochemical reaction and some heat is needed to avoid Li plating.
Never attempt to charge an Li near freezing temperatures
Li's thrive on frequent partial charge cycling. 40-80% is a good range.
Avoid going below 20% or over 90% except occasionally for best lifespan.
High temperatures and high cell voltage are Li's biggest lifespan risks. Avoid running the phone when the battery is hot (>102F) or provide cooling. Keep it out of direct sunlight especially when charging.
Store Li's in a cool, dry place with a 50-70%charge, not 100%!
GSMArena:
" We tested the Galaxy A33 with the said 25W USB-C Samsung charger, and it replenished 50% of the battery in half an hour.
A full charge took 1 hour and 15 minutes, and in fact, that was the cited expected time to full charge by the software as well. "
Fast charging will yield roughly 2%@minute from 0-80% if battery doesn't go into over temperature ramp down. Time it to get the nominal rate for that device ie how many seconds per 1% when fast charging in the 40-70% range, probably 30-40 seconds per minute when new. As it's capacity from degradation drops so will this rate.
Charge rate will ramp down at around 80%, then again at about 90% to protect the battery.
Temperature is the biggest variable.
If the battery is below about 60F fast charging will not engage for that charge cycle in order to protect the battery.
Fast charging rate not clear cut as the power controller optimizes charge rate per conditions and will reduce charge rate if they're not in the optimum range.
Constant erratic fast charging cycles with a known good brick/cable indicates a battery failure.
Any battery swelling is a failure, stop charge and replace it asap. It can damage or destroy the phone
Replace the battery when it reaches 80% of its initial capacity, the end of its useful service life. At that point it's considered degraded, degraded Li's are far more likely to fail. An Li can fail at any time... it can happen fast. Cataclysmic failures however are rare.
My new A33 came a couple of days ago with about 30% charge. I used it a bit lightly with the intention of depleting it(so I can have it full when I root it), I haven't yet installed the SIM, and when it was about 15% I got tired so I downloaded an app "Generic Battery Drainer" to deplet it quicker until it reached 0% and turned off, then I charged it to 100% with the charger I purchased which came today(an OEM one)
I didn't know that you should never deplete the battery to 0% and also did not know that the battery should not be charged to 100%
I obviously also didn't know the dangers of high temperatures, because the drainer app took the cell phone to about 104ºF
What prompted me to post my question actually was that from 0% to 100% charge it took about 3 hours. So I'm wondering if maybe I should check if the OEM 25W charger that I got does not charge fast as advertised?

You should fully charge a new battery before using. Are you using the cable that came with the brick? Is the wall socket wired correctly?
3 hours is far too long for fast charging.
Observe while charging to see if it's fast charging be % per minute.
The display must be off or it will skew the charge rate badly. Start and maintain it in temperature parameters described when charging.
If it drops out of fast charging because of temperature it will likely not reengage unless the cycle is manually started again ie unplug/ plug back in. Don't try to fast charge a hot (>98F) battery, it won't work. Cool the battery down and use cooling while charging. A damp microfiber cloth and/or fan work well.
Briefly turning on the display will not break the fast charging, it will resume once you turn off the display. Low current drain apps like Poweramp/bt can be used while fast charging but not high current drain ones.

I used the cable that came with the OEM charger that I purchased, seems to be identical kind of cable as the one that came with the phone.

Should be good to go.
When you get to 40%, try again... it's probably ok.
Try using a wall socket on a different breaker. Line voltage fluctuations won't effect this brick however neutral/ground fault might. Avoid using on a circuit with large induction motors on it ie microwave ovens, friges and A/C
