Poor battery life on the first day - Samsung Galaxy S9 Questions & Answers

Hello everyone, yesterday I picked up a brand new Galaxy s9 exynos version. At the very start, the battery gad around 42 procent, it lasted me about 2 hours till it went to 10 percent. Later I charged the phone to 75 percent, went out with friends, and after around 35 minutes, doing nothing in my pocket, it dropped 4 percent. After some heavy usage, I decided its time to do a full charge for the first time. I will post the screenshot down bellow. I've heard, that its just the first day, and it will get much better after around a week, although im a bit affraid, that the battery life wont improve. What do you all think?

You are meant to charge it as soon as you get it 100%. You need to calibrate your battery now and maybe do a factory reset.

Don't worry about factory reset, just drain the battery to 0 then charge back to 100 for the next few charge cycles

[Q] Extended Battery Readings

I could have sworn I've seen a thread for this but I just can't seem to find it.
Tried my best to search so I apologize if this is a repost.
So I've been on the extended battery for over a week now and must have gone through about 10 charge cycles so far.
Few days ago, I noticed my battery was at 15% and I was nowhere near a charger. I had the phone off for about an hour because I needed the remaining juice at a later time. Once I turned the phone back on, I noticed the phone was back UP at 25% remaining without ever charging it.
Thought it was a one time fluke so I didn't care much for it.
Today, I had a screen protector come in and since it was a wet apply, I turned the phone off at around 25%, left it off for about an hour an a half for the product to dry a bit then turned the phone back on.
This is the battery reading below:

}
If I remember correctly, the reading went back up to about 31% after turning it on. (Don't mind the gap in mobile data reception.. I was in a plane during that time).
I've calibrated this battery once on the first cycle so I'm not sure why this would happen. Is this a known issue?
Currently on stock, unrooted 4.0.2.

[Q] Is It normal for cell standby to be 60% of batt drain?

I just got the galaxy nexus a few days ago I've rooted it and installed the latest miui from miuiandroid.com as well as the trinity kernel.. when my phone locks I lose signal thats one issue but I would have thought if anything that would make the battery better? I pulled up my battery stats and my cell standby is 66%.. is this normal for cell standby to be the main battery drainer?

Losing signal = constantly trying to reacquire signal.
So no, it is not your friend when it comes to battery.
it is also 66% of the 39% of the battery lost
Is this just a standard bug in 4.0.4 or is this fixable?
The signal cutting out when the phone is sleeping is a known bug of 4.0.4
If you took your phone off charge in the morning and didnt hardly use the phone for the 13 hours then yes your standby would use the most because its not been doing anything all day.
If you had the screen turned on for long periods of time then the screen would take up most battery etc.
By the looks of it you have hardly touched your phone seeing as screen has only used 6% in 13 hours so its most likely nothing for you to worry about if you didnt use the phone much.
When i first got my nexus i tried not to use it as much as i could for the first charge to see how the battery life was and cell standby used up the majority of my usage because the phone had been in standby all the time

What's up with the battery?

What the hell is up with battery? It first charges at very fast rate usually 2-3% every 5 mins then slows down and when reaches around 70% it jumps to 100 % . it can retain its charge to max about 9-8 hours with minimal use and 2-3 hours with heavy use, I have tried clearing cache/battery status from recovery and different ROMs/kernel/radio all give same result

I had the same thing with the desire hd I had, basically lost the top 30% capacity I believe. Once I replaced the battery it was perfect again.

Slow charging and heating

Despite this phone being just perfect in every other way, a couple of things​ about it is just frustrating the heck out of me. I don't know if it's just my device or if this is a normal thing, but my Pixel XL charges SUPER slowly. Taking about as long as an iPhone to reach 100% on low percentage and 40 minutes to an hour with 50% and above. My 6p charges faster than this using the same charger. Not only that, but my phone gets really warm when charging and slightly warm with general use. Does anyone else experience this?

I experienced just yesterday. Normally the phone charges about 1% every minute for me, but yesterday it was 1% every two minutes or something, got really annoyed, turned off the phone, charged normally! And yes, there was a little bit of heat too, nothing complaining worthy but it was there, but then again I use a full back case, which I will remove shortly. The phone/SoC has some thermal throttling surely, cause several times I noticed the phone's performance would drop down severely while charging.

Lg K430T battery inaccurate

LG K430T Mediatek version, takes nearly 6 hours to fully charge from 1% with the Aukey quick charge 3.0 and its cable, when it reaches 15% drops like a sinking ship and shuts down at 9% (it varies) before reaching 0% . Removed the battery for a minute in one of the pictures, this is why the curve is separated as the % jumped below and above . Performed a hard reset with the power and volume button. Currently running its last update, android 6.0 with the stock/official rom.
