q: about extended battery for evo

i just got my 3500 battery for my evo i charged it over night but when im using it today it seem like im using my stock bettery 4 hrs already down to 68 percent. i didnt talk much and i didnt surf much watch little bit of youtube.

so many variables, kernels and all that. try calibrating, full charge and resetting batt stats if you didn't already.

I am having the same issue, and from what I have been told, you MIGHT need an external battery charger to get the battery to FULLY charge. Something with the Evo stops the extended batteries from fully charging to their capacity.

There are many of us who believe that the algorithm used to determine battery charge capacity is flawed. When the 3500 mah battery is truly filled to capacity, battery life is amazing. I go through a routine to get my Seido 3500 to completely charge. Place the battery monitor widget on your main homescreen (it is free to download from the market) I charge it until the LED turns green or until the battery monitor widget alerts me audibly. Yes, it can be set to emit an audible alert when the battery reaches 100%. Afterwards, I unplug and wait 60 seconds. If after 60 seconds the battery monitor widget displays less than 100%, I resume charging. I repeat that process until after 60 seconds the widget still displays 100%. Once that happens, I can easily get over 24 hours of use from my battery. My routine is somewhat tedious, but it is effective. Like others have stated, a dedicated charger for the Seido may work better. Anyway, I use this same routine with the stock battery. I hope I was helpful to you.

I think I will give your method a try and see if that will work for me. I get approx. 5-6hrs on what shows a full charge on my 3500ma battery at this point.

I charge my battery til light is green, then leave it on for ~2 hrs. Look at the waveform on bmw. You'll notice after the charge level reaches 100%, the mA waveform looks like a saw tooth waveform. Initially it will be a high frequency pattern, then it will begin to slow down... Once it reaches this slow down state, that's when I consider my phone charged.

Here's a visual of what I was referring to above. The phone's on the charger the whole time, unused (idling), screen off.
mA on top, % on bottom.

Same graph, mA on top, mV on bottom

to add another method to the mix it's similar, not trying to knock on any of the others mentioned at all
I found that the most accurate way to utilize the BMW for a full charge is reading the mA's..
..after either placing widget on home screen or activating >menu>settings>monitoring preferences>monitor without widget>history update rate>60sec..
..then after light turns green check mA's in history it will be positive mA until it goes from triple digits to double then single when it reaches zero its at capacity/full then it will stop charging and start to go into negative mA. unless its a sbc kernel it should keep bumping a single digit mA if nothing is keeping it awake..
..unplug at zero and it will stay at 100% for a long time on a extended battery. best I got was 10 hours (at100%) with minimal use and 5 with moderate on a 2400mAH.

I, too, watch the mA using the battery monitor widget (bmw) and many of us used to charge the battery and wait until the mA dropped to 0. The problem is that many of us could never get to 0 or by the time it got to 0 the phone had been charging for about 8 hours...of course I'm being overly dramatic here...lol...The point is this: when the phone's LED initially illuminates indicating a full charge, chances are it is not full and you will have to employ some additional charging methods to truly get a completely charged battery. Several methods have been offered here. Pick one or try them all and then decide which one is acceptable to your tastes and patience level. Take care.

@madflasher, your battery history log is indicative of a SBC kernel. Is that what you are using?
A non sbc kernel has a bump type strategy, while sbc is trickle.

gpz! you are correct. nice catch! My bad I should have stated that...to go along with what works for others this is what worked for me but like I said, was just adding another method to the mix...I know the debate on sbc can get pretty heated...there's so many variables when it comes to battery life

[Q] Note 10.1 2014 charges very slowly

I just bought a new Note 10.1 2014 edition, everything works fine, except the battery takes 30 hours to charge to 100%!
The screen was off the entire time it was charging, but the device was still on, in airplane mode, with power saving mode on and the gps was off.
I'm using the stock samsung charger I got with it, but with a american-european converter, although I don't think that should matter, because on the box it said it could take over 10A, and the stock samsung charger is 2.0A.
The device doenst register the charger as a USB or anything, it realizes that it's charging via AC.
Is my cable, samsung charger or converter just dirty/broken? or is there something wrong with the device?
ps, I have Cleanrom 2.0 installed, and use some Gravity Box tweaks
Thanks

If you have the Snapdragon P605 , then this should take around 3-4 hours for full charge from 0%, while Exynos processors P600/601 normally takes 5-6 hours charge time.
So probably you have a defected or malfunctioning charger or cable , try charging without the converter & see if the case is still the same , then that will be either a faulty cable or charger.

It does if you have a P-605 with Qualcomm's QuickCharge feature. See the pretty little stylized "A" in the upper left corner of the graphic I posted? It's the AnandTech logo. They don't lie and have been performing objective standardized tests on mobile devices longer than you've been an XDA member (2007). If my choice is believing their 7 hours and your "4-5 hours tops" guess who I and most people here are going to believe? And my P-601 does take about 7 hours to charge which is a hella long time especially when you're traveling.

LOL, I'm literally timing mine as I type this - I will report back the exact time it takes from 5% to 100% - Using the standard wire and socket Samsung provided. Curios if people timed their devices if they would all be the same time frame - I know my first tablet took something around 6hrs to fully charge will see what this one is like.

mine charges at 21-24% per hour up until 80% where the trickling starts. at that point it constantly takes 90 minutes to top it off. i doubt that anand lies, but he's only testing one sample and he's reporting what he gets from it. mine takes 4-5hrs depending on how frisky the tablet feels in taking some juice.
i don't have any logs so bmw pro but if i ever remember to let it drop down so i can get a long charge logged i try and post it.
it's not like any of us are gaining any internet fame by reporting a 5hr charge or getting any pay.
cables do affect the charge rate a lot. so if you get less than 5hrs then check another cable. this this is very pick on the cable for some reason.

mine takes 3-4 hours....its a p605 probably you have a defective piece or try another power outlet

Holy crap. Just like the Exynos/S-800 N3, the Exynos/S-800 N10.1-14's use different charging circuitry and get very different results. AnandTech tested an Exynos P-600. Like my Exynos P-601 it takes 7 hours to charge from 0-100%. People with S-800 N10.1-14's have been reporting getting a full charge in 5ish hours which is about the percentage difference between the two different N3's. You'll also notice the second runner up in longest charging time is the Exynos-based N10 which, like the N10.1-14, uses a microUSB port to charge. If you adjust for the smaller battery, the Exynos N10.1-12 with a 30pin connector charges about 20% faster than the N10.1-14 with a USB charging port. N10 owners that bought the optional pogo pin charging module have been able to shave about 30ish% off their charging time which means it's not the battery or SoC causing prolonged charging times via USB on the N10.1-14 and N10.
Conclusion?
The P-605 is one of the fastest (if not the fastest) large format tablets.
The P-600/1 are slugs which is probably as much due to microUSB as a charging port rather than what the battery/SoC can handle as evidenced by the N10's improved performance when using pogo pins.
P.S. - Here's the N10's charging graph (via USB) and it's pretty linear. So Samsung (who builds the N10) may have done something in terms of faster charging mid-charge for the N10.1-14 but if they have that power they certainly didn't apply it on the N10.

P.S.S. - P605 owners go away. "Slow charging" has nothing to do with you and you're just muddling the thread which admittedly should (re)titled "Exynos N10.1-14 Takes Forever to Charge."

Their belligerently calling people liars and making it seem that people posting different result are daft. If you can dish it out you should be able to take it. But seriously, this thread's very poorly named as it doesn't identify that only the P-600/1 are slow charging. I knew that from other discussions already had on this forum. So, while maybe a tad belligerent in their approach, people that didn't know there were differences between the Exynos and S-800 versions of the N10.1-14, could have assumed they were the same.
Here's the difference between a device using Qualcomm's P4981 dedicated charging module (QuickCharge) and a device using standard charging circuitry. Pretty impressive. Numbers below are for a 3,300mAh battery. And the dedicated charging circuit is what makes charging via USB mute on S-800 devices.

Okay here are my charging results which I have timed.
Started charging 16:20 @ 5% - https://www.dropbox.com/s/yeoup9hafrmw93q/Screenshot_2014-01-13-16-17-41.png
Finished charging @ 21:25 @ 100% - https://www.dropbox.com/s/gxmcpp0aq9od5l2/Screenshot_2014-01-13-21-24-28.png?m=
So charge time of 5 Hrs - like its been said, it charged very fast till 85% then slowed right right down!
Mind you I did not use the tablet at any point apart from lifting the book cover to see progress. Personally I think the charge times is alright.

Here's a little food for thought from the SGS4 forum. It doesn't matter if the device being tested is Exynos or Qualcomm since QuickCharge was introduced with S-800.
spark001uk said:
With the advent of the S4, and its higher capacity battery, one could understand a higher charging current. However, I seem to have uncovered some findings that the charging system on the S4 is a bit more complex than first thought!
This is a bit techy, and assumes you have a basic amount of electrical knowledge, ie voltages, currents, resistance etc., but I'll try and keep it as simple as possible for anyone who may not!
To explain: The mains charger supplied with the S4 is a model number ETA-U90UWE, rated 5V @ 2A. However, the phone will ONLY charge at full current (which as I have measured so far, depending on what the phone regulates it to, typically sits in the region of 1.2 - 1.5A), when using the supplied charger (or possibly one of equal or higher current rating, depending on how it's configured internally), AND the supplied usb cable, OR any other usb cable, provided its shielding (the metal outer surface of the connectors) is connected at BOTH ends of the cable. Use a cable that doesn't have this shielding, and the charge current drops, regardless of whether there is plenty of current available or not. Use a different charger with an unshielded cable and the current drops even more, again regardless of whether it can supply plenty more current.
My assumption on this, is possibly an effort by Samsung to avoid the scenario of sticking 1.5 amps down a flimsy cheapo cable, the wires of which will likely be too thin to carry it.
After doing some probing around with a meter, I have managed to find a slight difference with the charger itself, compared to a generic one. In a generic one, the two data pins are usually just shorted together, which tells most phones that it's a mains charger rather than a USB port. On the Samsung one on the other hand, the pins appear to be shorted together, and also connected via resistors across the supply line (known as a potential divider), which holds these shorted data pins at a certain voltage. This is what tells the phone what sort of charger it's connected to.
Attached are a couple of diagrams to show the difference between the two chargers. There are in fact various setups of resistors that different manufacturers use to set the charging current, so it's quite easy to run into compatibility issues!
To make this a little less confusing I have done some preliminary experimenting, and I set out my results here.
For the test, I used combinations of 4 different usb style mains chargers: an apple iPhone one rated at 1A, an iPad one rated 2.4A, an HTC 1A one, and the genuine S4 one. With these I used two cables - the supplied Samsung S4 one (which is shielded), and a cheap generic one (which isn't). I started by measured the charging current directly with a meter, by using a very short usb breakout lead I've made, enabling me to interrupt the 5V line. However, I soon noticed that the use of any extension cables, even shielded, can lessen the chance of maintaining a good shielding connection, so I continued the exercise relying on the "galaxy charging current" app to get a reading.
Charger.................... Cable................ Current (A)
=====================================
HTC 1A.................Generic..................... 0.5
HTC 1A.................Samsung S4..............1.0
Apple 1A...............Generic......................0.5
Apple 1A...............Samsung S4..............1.0
Apple 2.4A............Generic......................0.6
Apple 2.4A............Samsung S4..............1.3
Samsung S4.........Generic...................... 0.8
Samsung S4.........Samsung S4...............1.3
So as you can see from these results, the original charger makes a difference, and the supplied cable (or a good quality shielded one) makes a further difference. If you have any further findings please feel free to add them here.
I can see that this is going to confuse some people, as it has me, as I'm sure some will inevitably try charging up their phone on generic chargers/leads at some point, with potentially long charging times resulting!

that's been my experience. i've gotta make sure that i have the right cable AND charger to get the full blast - using p600. the fastest charge comes from the stock charger and a car charger i have (powergen 2.1A). no charger has ever reached 2A and the highest i've ever seen is 1.6A.
regardless of the fact that one's tablet may charge a few hours faster than someone else's - five+ hours for a charge is waaaaaaayyyyy to freaking long! my samsung ativ 500t has about the same battery capacity but charges in 90min. the 700t charges in 2hrs. of course using 12V 3.3A charger is giving a lot more juice than a 2.3A 5V charger is, lol.
one thing i noticed is that occasionally, the trickle ( charging past 80%) would sometimes drop to 300MAh instead of the normal 600 to 900. if i catch it, i just unplug it and replug it and it's back to normal. dunno what causes this though.

so many people facing that problem, we still don't know what cause it, is it software problem or hardware problem, but in my country (Indonesia) someone from Indonesian asus forum facing that problem and he brought his phone to ASUS service centre, he waited for about 1 week, and after he got his phone back asus had changed the motherboard and the battery, so I think battery jump is caused by hardware problem.... cmiiw

How long does it take for battery to jump from 42% to 100%? The 2.3GHz plus 4G ram (ZE551ML)" is bundled with 18W adapter which has quick charge. Please see the following link regarding quick charge: http://www.asus.com/us/support/FAQ/1011185

I had the same problem with an lg G2. If it jumps that much in a couple of seconds then it is really hardware, can be the charger but most of the time its the battery and internal power supply. You just had a bad luck, it can happen anytime to anyphone, Asus have excellent support. Contact them by phone.
p.s: Nice to see Asus staffs posting on xda.

from 0 to 42% it takes around 1 hour after that It jumps instantaneously. to 100%
Yeah i use 18W adapter.
I get battery backup of around 3-4 hours only.

My problem is different my problem is fast charging no working takes ages to charge says 2 odd hour charge or 1 hour 52 and it still takes ages plugged it in 2day 2 charge it said 7 hour I thought wtf anyone know how to help please

I cannot be 100% sure as it never happened to me with this phone but with my old g2 cellphone , it was hardware and I had to replace it. Your best bet is to call Asus by phone.
@kumarsaurav11, 0 to 42% should take much less than 1h. It should be 0 to 60% in ~38 min with that 18w charger. Same advice here.

Mine goes from 40 to 0, 3rd time in a row, brand new, just received it this morning, ZE550ML, if problem persists by the end of the week, I'll be returning it first thing this monday and getting a Mi 4i instead.

Mine is jumping from 78 to 100..
It charges to 60 like at quick charge and then after that it gets super slow..like takes hour+ to get to 78 or so..is purely software related cux in getting around 5-6 hours of sot similar to any user with no jump problem..hope it fixes tho
Plus its happening to half of the users that cant be all hw related..

We are mostly running 2.19.40.22. Never had it with my zenfone 2 4gb ZE551ML, I don't know about the 550.
Yes, quick charge is programmed to only charge up to 60% 18w 9v 2a, then it will charge at a lower than other phones speed at 7w 5v 1.35a, specs are printed on battery heatsink. Charging is 2x slower after 60%. It could be for safety as quick charge will heat the phone fast.

Yes, quick charge is programmed to only charge up to 60% 18w 9v 2a, then it will charge at a lower than other phones speed at 7w 15v 1.35a, specs are printed on battery heatsink. Charging is 2x slower after 60%. It could be for safety as quick charge will heat the phone fast.

I know but it cant be a hardware problem if all of sudden after v2.19 ALOT people start complaining about battery jump issue..im on 551 tho..

To really know if its hardware, reboot in recovery, clear data&cache, then flash the original firmware from asus website. Start with earliest firmware and try to pinpoint with which one does this issue occure or not.

Does anyone know if cyanogen mod fixed this issue?

This is most likely hardware as I stated earlier. Did it happend to you in Stock?

Just arrived my zenfone 2 from assistence, with a document says:
Fault found: Battery error
Article: SW Update
Testing now and i found that the battery now jump from 78 to 100 instead of 66 to 100.

I had this problem too, battery jumps from 70% to 100%, so i did a calibration and now the battery is perfect (I got double autonomy also).
For calibration:
1) Discharge the battery under 10%
2) Switch off the mobile and charge it 2 hours more from a full charge
3) Unplug the cable for 10 seconds, then plugin again and charge the mobile for a few minutes
4) Switch on the mobile with the cable plugin and when the android system is fully loaded, unplug the cable
All of this for 3 times

Just for compare, if you or anyone can install "battery monitor widget" app and tell me the voltage of the battery when it is full charged, mine is 4367mv.

A "Battery Care" trick to always limit charge at 90% and extend battery life

A "Battery Care" trick to always limit charge at 90% and extend battery life
It is well known that keeping modern lithium batteries always 100% charged reduces battery life
Several laptop makers have introduced software solution in order to keep top charge around 80% limit. I was glad to know that Sony offers a "Battery Care" feature, a way to limit battery charge in our Xperia 1 II.
But the choosen approach is too soft in my opinion: Battery Care tries to learn when I put the phone on charge and when I unplug it and makes sure it is quickly charged to 90% and then injects the final 10% just before I unplug it my phone will ideally stay 100% charged just a few minutes. It just works if my behaviour is predictable and still tries to charge the phone at 100%.
This how the automatic Battery Care setting works. However I just realized that using the custom setting in a tricky way, I can make sure that my phone will never be charged at more than 90%
I just have to find a time when I am pretty sure my phone will never be connected to the charger. For me 5 in the morning is a good choice, I never leave my phone charging at night.
Then I set Start charging time at 5:01 am and Target time for full charge at 5:00 am. (To reach Battery Care settings: Phone settings > Battery > Battery care)

When plug the charger and Battery Care is activated, I get a notification.
When I unplug the charger I receive a message warning that the charge is not yet completed. Since this is exactly the wanted behaviour, I dismiss the warning and check the flag to disable such warning in the future.
The result is that my phone will never be charged more than 90%.
To stay in a more ideal charging range 40%-80% I also use an app with an alarm that alerts me when the charge is outside this range but with this custom Battery Care setting I have a safety net and I am sure that even if I ignore the alarm, the charge will never be excessive.
By the way another tip to prolong battery life is avoid using quick charging when possible, so I use my original charger (or my PD compatible charger) just when I am in a hurry, otherwise I use an ordinary charger.

Thank you very much for your tip!
Your way works for me too. [emoji16]
And I thought all the time that this battery care thing is useless because it doesn't fit my needs (stop at 90 %) and turned it constantly off - for years.

Too bad that this function is not versatile enough and we have to use these tricks to do something with it.
I don't know much about other Sony phones, how long has this feature been around?

My XZ Premium had battery care, but it was automatic. If my sleeping patterns changed, like on weekends, or on vacation, it would fail to activate because the phone predicts my sleep patterns in order to activate battery care.
Enter the Xperia 1 mark II. I was ecstatic when I found out it has a custom option, where I set the target time. This way battery care is NOT hit or miss. I love it.
Settings > Battery > Battery Care > custom

Do you know that when battery care is turned on, the maximum charge is 90% even if it displays 100%

The screenshot says the battery gets loaded to 100%, after pausing at 90% at night time.

But having in between 40-80% means you have to charge it more frequently, so, doing that doesn't also kill the battery life?

What charger are you talking about? I actually tried this yesterday, the original charger that came with mi X1 II was a 18w charger.. and it does charge the phone way too fast for my liking(around 1 hour). So, i tried the original charger that came with my older XZ1, and oh boy, almost 8 hours later, the phone didn't even make it to 50% charge (from 15% when I plug it)

Yes you will need to charge it more frequently but you can perform much more charging cycles before affecting battery life: https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

I agree the fast charger is too fast and and charging fast will shorten battery life too: https://batteryuniversity.com/learn/article/ultra_fast_chargers
I don't know about your XZ1 charger but I guess any 1A USB-C charger will do the job. At work I'm using a common USB Monitor port with this adapter (https://www.amazon.com/PortaPow-3rd-Data-Blocker-Pack/dp/B00T0DW3F8/).

Why not built in on phones ? I see chargie limits and cuts off your charger at xx %0. By Bluetooth signal. Great idea so ez to have bt chargers do the same

General How charging works on Pixel 6 and Pixel 6 Pro

How charging works on Pixel 6 and Pixel 6 Pro
The Pixel 6 Series was designed to deliver battery life that lasts all day. Incorporating some of Pixel’s largest batteries encouraged upgrades to charging as well: from a user perspective, a bigger battery shouldn’t have to mean it takes longer to charge to 100%.
Battery cell design determines the maximum charging power required for smartphones. A battery can be designed for high energy density, or for fast charging power capability, which requires trading off capacity to minimize battery degradation.
Google has designed the high energy density cells in Pixel 6 and Pixel 6 Pro to strike a balance between battery life, longevity and fast charging. Regardless of available power coming from the wall plug, the actual power delivered through a full charge cycle varies over the course of a single charge. The charge rate at any moment is based on factors such as battery cell and system design, temperature, system usage, and state of charge.
We’ve optimized Pixel’s lithium-ion battery for high charge rates when the battery level is low. Pixel 6 can get up to 50% in around 30 minutes (with Google’s 30W USB-C Power Charger), and quickly reaches up to 80% in about an hour, depending on device usage and temperature.1 The peak power that Pixel 6 and Pixel 6 Pro draw from the wired charger is 21W and 23W, respectively. As the battery gets closer to full, charging power is gradually reduced in order to improve battery longevity.

Pixel may also pause charging above 80% under certain conditions, and if you enable Adaptive Charging, Pixel can optimize charge rates for gradual overnight charging. Taken together, these approaches help you charge your Pixel quickly when the battery is low, but also help minimize degradation to preserve the lifespan of your battery.
Wired charging and wireless charging
The Pixel 6/Pro is designed to work with existing USB PD and BC1.2 wall chargers. However, it can charge more efficiently with chargers like our 30W USB-C Power Adapter which supports the new USB PD 3.0 PPS standard.
Wireless charging is typically less efficient, and is therefore slower, than wired charging. The new Pixel Stand was designed along with the 30W USB-C charger to enable fast, convenient wireless charging, with an active cooling fan to dissipate heat. Together, the new Pixel Stand and Google’s 30W USB-C Power Adapter can deliver the maximum power needed to charge the Pixel 6 and Pixel 6 Pro rapidly.
1 Charging testing conducted by Google in mid-2021 on pre-production hardware and software using default settings with the device powered on. Charging speed depends upon many factors including usage during charging, battery age and ambient temperature. Actual charging speed may be lower.

By sheer chance, I decided to give the Google Play Store a look a few hrs ago & the latest model of the QI charging dock finally went into pre-order.
Overpriced, you bet, but, I ordered one. I have yet to charge my Pixel 6 Pro w/nothing but a wireless dock (Samsung's latest) & it's sloooooow.
Hopefully, Google's dock will improve upon that.

I don't get all the worries about charging. I use a generic qi pad I bought several years ago. Just set the phone on it before bed and its 100% by morning, and has enough juice to run for 3 days easy.
Really what more can you possibly need? Oh my god it dropped to 99% must charge right this second!!!!

Everyone's needs are different. I prefer to baby my battery so I only charge to 75%, and rarely let it go below 25%, and I have never quick charged any phone. I still get 24 hours in that charging range.
Some other people are on the go, go, go so the want all the juice they can get. Then there are those between.

Me neither, whack it on charge and either take it off when its been at 100% for a bit and I've noticed or when i wake up.
Lithium cells have charge circuity that prevent over and under charging so 100% and 0% are never that anyway.

I've noticed at times that the phone is only charging at like 5-6 watts, even at something like 30-40% battery.
I'm not sure what causes that, but the charging watts fluctuates a lot.

For me it charges fast until it reaches 80%. It then trickle charge from there. I seem to be a minority in liking this charging method as I'd like to keep battery healthy rather using super ultra fast charging.

So, Googleeeee is saying there's no need or way to improve it...

@galaxys
What I'm reading is a long-winded explanation saying that they aren't going to change the way the phone charges, and the excuse is..."extend battery life".

When is the anticipated delivery date for you? Mine says around mid December, between the 18th and 20th. If they send it through FedEx, more than likely you can add 1 week to that.

in 1 way, i'm surprised they want to try to extend battery life. most people switch phones already every 1-2 years. why not kill the battery earlier and force pple to buy another phone to upgrade? more money for them
this is partially a joke, partially not

I'm ok with the charging model. I've little interest in wireless charging due to the relative inefficiency: although I see the convenience argument, it doesn't provide enough benefit (last used it on the N5, which I sold within a month or so after purchase).

It was convenient with OnePlus phones, specifically OnePlus 8 Pro, and OnePlus 9 Pro.
They have the best wired, and wireless charging. In my case the OnePlus 8 Pro I had charged a whole lot faster than the P6P, even significantly faster than the S21 Ultra my wife has, especially during wireless charging.
The OnePlus 8 Pro could hit 30W both wired and wirelessly.
The biggest issue with Google is that they are too aggressive with the charging curve, and that last 15%-20% takes way too long. If they followed Samsung's charging curve, and allowed at least 25W, I would be a lot more ok with that.

I ordered my black P6P/128 on Ocrt. 29th (what - about 2 weeks after announced?) and it said it would ship January 18-19th. Suddenly, I checked a week later and the delivery changed to November 9th.
It is a pure joy to use. Finest phone I have ever held.

Maybe. I ordered the phone on the 19th, about 2 1/2 hours after the presentation went live because the site kept crashing.
It was supposed to be delivered Oct. 27th, I didn't get it until Nov. 3rd because FedEx kept delaying the delivery.

The quoted shipping dates ranged from 12/15-12/20,depending on which speed was chosen.
The only reason I chose the fastest speed option was to (hopefully) get ahead of the last-minute shipping chaos,'tis the season..............

I'm fine with preserving the battery. It certainly better than the extra security explainion for the FPR.
That said, if you start offering a 30W charger the same time you introduce a new phone, I can see why people thought the phone would charge at 30W. Google should've been clearer.

For fairness’s sake, needs differentiate.
Some people want FULL POWER INSTA FULL WILL SWITCH PHONE IN 10 MONTH ANYWAY YOLO BATTERY HEALTH, GIMME 200 WATTS AS LONG AS IT DOESNT GO KABOOM WE GOOD
Then there are people like our roirraW "edor" ehT here that want to baby their battery (which makes a lot sense), so not too low, not too high - aaand as he said, everything in between.
What bothers me now is that Google doesn't give us a choice (I like that about Samsung in terms of charging).
Google should give us charging modes, like
1. FULL POWA!
2. Adaptive, according to temps, wakeup timer, whatever
3. Slow as heck, have fun using your phone next year
A choice is always better than none.
I - as an example - would like the automatic choice
Adaptive overnight + FULL POWA during the day.
- since I rarely chose to charge my phone "not" at night, that means IF I want to charge it during the day, it means I am running out and need quick juice. And in case I need quick juice, having some 10 Watt charging speeds with my 30 Watt charger, that would definitely infuriate me.
Is hasn't happened yet, since the battery is big and overnight is enough, but it could happen - and in that case, I want a good solution.
