With the display the device ought to come with a larger or more powerful battery. Even with fast charging, it is cumbersome and at times embarrassing to find the charging point, outside of the home.

Note 8 only has extra 100mah battery while being much larger phone.
what i figured out about the battery is, it cuts off at 3.6v which is pretty high for a Li-Po, as my M8 cut off at 3.3v, and you could get longer with a lower cut off voltage, but it's probably done due to the fast charging and to help not go all note 7.
Most fast charging features will charge your device fast up to 50% afterwards it will charge the rest of the battery at a more slower rate.

Lithium ion batteries hate heat. Since it tends to get a bit hot while charging, and I don't care how long it takes to charge, I have reduced the AC charging current to 450mA like a USB socket. Can anyone think of any negative effects this might produce?
Takes longer to charge, otherwise no.
But honestly, the little heat it produces when charging probably doesn't matter in your phone's useful life.

If I'm not using it I agree, but if I happen to be using the phone while plugged in it gets plenty hot. Much more so than normal use (I have extreme CPU and GPU undervolt).
i charge my 2 batteries with a wall charger, it charges at 4.2v, 350mAh, it takes like 6hours to complete
i dont do this because of your question but it is much simpler swaping, then charging via usb,i get better cycles like this, swap every morning.
I am seeing too many battery misconceptions. Let me clear them up.
STORAGE:
Lithium batteries like to sit around 50% for prolonged periods. If you need to power down your phone and store it, do it around 50-60%.
STATE OF CHAGE / BATTERY LEVEL
- It will NOT hurt to keep your phone on the charger. The charging circuitry cuts off power once the Cell hits 4.35 - 4.4v (If it did not, your battery would swell and heat up and then explode or catch on fire or both)
- It is MUCH more harmful to deplete the battery than it is to keep it full. Lithium batteries DO NOT like to go below a certain voltage depending on specific chemistry formulation.
For Example: Chevy Volt electric car Lithium battery is set to stay within 30% - 80%. They are limited to never exceed an SOC of 80% and never go below 30%. Source: https://en.wikipedia.org/wiki/Chevrolet_Volt
To expand on this. It is BETTER to keep the phone at 95% than it is to keep it at 5% for example. I personally would NOT want my battery falling low enough that it gives a low battery indication (usually around 15%). Usually I do not want it hitting 30%. That's a good rule imho.
CHARGE AND DISCHARGE CURRENT
Lithium batteries prefer to be charged slowly and discharged slowly. They do NOT like high charge and drain.
You guessed it. AVOID high charge scenarios such as Fast Charge. AVOID fast discharge scenarios such as gaming with high brightness etc.
TEMPRATURE
Lithium batteries do not like getting hot. They don't even like getting warm. Getting hot hurts it. Getting warm isn't as bad but it DOES degrade the total capacity over time.
Again, this is usually caused due to high charge or discharge scenarios.
It also ties in with Fast charge, wireless charge and especially wireless fast charge. Wireless charging is not efficient and energy as wasted as heat.
Personally I disable fast charge and do not use wireless charging. Good old USB Type C already charges quickly enough for me.
TLDR: Disable Fast Charge. Try to use USB Type C charging instead of wireless charging. Disable stuff you don't actually use. Try to keep power save on even if using it with very little power saving settings. Try to keep brightness at a reasonable level and not too high (This reduces AMOLED degradation too).
Remember: THE BATTERY IS NOT EASILY REPLACEABLE IN THE NOTE 7 !!!!!!!! Therefore the more you baby it, the longer it will hold it's charge and the lower the chance of the battery going bad.
My old Notes (Note 2 and Note 4) both still have VERY good original batteries because they were well taken of.
Good luck !
But I like fast charging and wireless charging lol
Ironic that when your phone is new, this is when the battery gets hot and used a lot. Perhaps with the water resistant phones we should update the firmware and restore the backup under water to keep the phone cool!
I will be sure to disregard just about everything in here. Guy is spreading false panic.
Actually "store mode" example: found in 7420 kernel source is 60-70% capacity. There are a lot of checks within source including battery swell etc. Don't fret about things, use your device. It's not as delicate as you may think. Who cares about the efficiency of wireless charging. Great if you've got it
90% won't keep beyond 2 years, just enjoy the thing !!

My device arrived at 59% charge, ties in with what you say about storage.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Sony Xperia X Compact can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Sometimes it is superfast and sometimes its normal!!
I have a charger with QC 3.0 and it charges with normal speed :/
It's reasonably quick with a quick charge charger. About an hour and a half for a full charge. But can get nearly half in half an hour.
I use a Choetech 55W QC 3.0 USB-C charging station along with the same brand cables, and Anker cables. There are a lot of bad cables out there so you have to watch what you buy. I made sure these were certified because I didn't want to fry this device, or other devices hooked up to the XC (there's that one Google developer guy who tests them).
It can charge in under two hours and the phone's battery gives off quite a lot of heat as a result when it's drawing a proper high load - which can't possibly be good for it in the long-term. Is the battery still going to be good after a whole year of use? Same high heat output with a Samsung charger+cable (same brand respectively), so it's neither the charger or cable causing it, just a very warm battery.
Would not recommend sleeping with your device if it's hooked up to a QC outlet - needs to vent that heat -- if you roll over onto it, bad things might happen.
1% at 77~78% is 2:19.9s
Keep in mind, that by design, a battery will not maintain a constant high current -- rather -- drops off slowly as it nears capacity (safe charging), so using %/min. is not an accurate gauge in charge time. So this %/min. will be lower when the battery is at 1~30% than +30~100%. Charge circuits never go by percentage either, but by voltage. An accurate reading would be on a DC volt meter bench.
Shenanigans and errata: My phone stays at 100% for a while after a full charge compared to when it goes down from 99%, so this is not an accurate method to test "full" and "empty" states.
I really miss the option to turn off the fast charging (it is present on my Note 4, for example). I don't need the fast charging, because I charge the phone mostly at nights. And I'm almost sure, that the fast charging will degrade the battery more, than the regular charging.
The thing is, the Mate 10 isn't officially available in my country, so I will not be able to change the battery (don't really want to disassemble it myself).
What do you think, will it be preferable to use my Note 4 charger (Mate 10 should use it as a regular 5V/2A charger), or maybe the native Huawei charger may somehow be more friendly? Maybe, any recomendations?
Btw, did batteries get any better in the past 3-4 years? Can I expect the Mate 10's battery to degrade slower, than the Note 4's battery? (it degraded noticably in a year, even without a fast charging)

You can control battery degradation with accubattery on playstore. Very great app.
Better to charge to 80 % max in order to degrade battery slower.
App gives good advices et a lot of infos.
Moreover, yes, supercharger probably degrade battery a bit faster but I think it's negligible

Thanks, but I don't see it a handy solution, to be honest. I charge the phone at night, so I can't stop the charging at 80%.

We're automatizing anything we can, and you're suggesting to wait for a notification everytime I charge, to pull of the charging cable. Wrong or not, but I'll stick with the "plug in and forget" option, cause its really easier to disassemble the phone once in a 1.5-2 years and change the battery, than to wait it charging to 80% every other day So, the questions about the charger selection and battery improvements in past 3-4 years remain open

Ok as you want dude but honestly have a normal charger is useless..
Are there any studies that prove that fast charging can degrade the battery performance faster?
A shower and breakfast is all the time it takes to charge to 80%.

Speaking as an electronics engineer (and not as an expert on batteries), I'd suggest that "slow and steady" will always be kinder to the battery, no matter how much technological work has gone into preventing the battery from destroying itself through fast charging.
Keep the SuperCharge charger that came with your 'phone handy in case you need an emergency top-up, but for overnight charges use an el-cheapo 1A USB charger. It'll be more than enough to bring you to 100% by the morning, and there'll be no chance of crystallising/drying-out the battery's electrolyte.

You're probably right but science proves now that the most important thing in order to maintain battery is to charge it to 80 % max.
Your point is to be kinder to the battery right?
Better way is to charge it less than fully.
But, anyway, you're want to be stubborn ?. So, buy a normal charger, charge phone fully the night and don't cry after if you're battery doesn't work well.
And to answer to your "question" better is to buy a huawei charger if you don't want for sure any problem...
its not a good maner to compare note 4 with mate 10
samsung usually uses low quality batteries in cell phones
but after s6 and note 5 it improved the quality
about huawei's batteries
the batteries are in high quality state
my brother has huawei honor 3c lte. he bought it around of 5 years ago. after years we couldnt realize a significant weakness.
so dont worry about mate 10 and its super charge
im sure that your device will be working in a good condition
Hi
Just bought a GT Neo 2 but didn't get the Realme 65W charger. I do have a Samsung EP-'T4510 USB-C Quick Charger 45W + USB-C Cable.
It's obviously not going to charge the phone as fast as an original 65W charger does but it's not charging as fast as I'd expect. Plugged it in earlier at 49% and it was at 91% 40 minutes later.
So what affects charging time?
Charging set up as follows:
1) Using extension lead
2) Using adapter to convert 2 pin EU charger to UK 3 pin
3) Samsung T4510 (45W) and the cable that came with the T4510
Do the extension lead or adapter affect charging time? Also does the cable affect it? Do fast chargers have to be used with a specific type of cable?
The charger/cable has to support the charging protocol of the phone or it will only slow charge.
Best to use a OEM brick/cable no longer than 3 feet.
Battery temperature needs to be high enough at beginning of the charging cycle for fast charging to engage. Minimum 72F, but 82-90F is best.
Fast charging may engage below 72F but Li plating becomes likely. Below about 55F fast charging will likely be disabled.
Above about 103F or about 80% capacity fast charging with be ramped down or disabled.
If screen is on, fast charging is disabled.
A battery fault will also disable it or cause erratic fast charging ie a battery failure.

One more question if you don't mind. Will charging the GT Neo 2 with the Samsung charger damage or reduce the lifespan of the Realme battery?

Fast charging produces more heat therefore will reduce the lifespan somewhat.
On my heavily used Note 10+ I now replace the battery every year or so to help prevent a battery failure, routine maintenance.
The charging curve is controlled by the phone not the charger. The charging curve should be near identical if both bricks supple the required peak voltage/amps and the phone power controller can communicate with the brick.
Thank you kindly. Much appreciated.

You're welcome. Play with it to see how it works.
Start the charge at about the same temperature then time how long it takes to gain 1 or 2% without turning on the main display. Watch when it ramps down during the charge cycle. It will vary but I see 2%@minute sometimes a little faster at the peak fast charging rate on the N10+.
To extent battery life limit discharge to 30% and top charge to 80%. Li's like frequent midrange power cycling; it extents their totals full charge cycles many fold. A 40-67% usage range is near ideal. Limit the current draw; higher current usage stresses the battery more as does back to back discharge/recharge etc cycles with no rest period.
That's one reason it's just easier to replace the battery. When an Li reaches 80% of its original capacity it's considered degraded and has reached the end of its useful service life. It should be replaced. Degraded Li's are more likely to fail which can seriously damage the device.
Any battery swelling is a failure, replace immediately.

That's all very interesting. I have often read about the 30 - 80 range. I used to own a Huawei P9 and always charged to 100 and that battery didn't last more than 2 years. Last phone was an A70 and that'll be 3 years old in June. Started getting random reboots recently and a quick Google said that's most likely down to the beginning of a battery failure. So just got this GT Neo "as new". It was obviously sent back to the online store by original purchaser minus the charger (replaced with a 5V 2.1A charger. Store had no OEM charger listed on site for sale so I agreed to take a the EP-T4510 charger. While it's not ideal that I won't be getting the fast charge of the OEM charger, it's far from a major issue for me, as long as I'm not going to damage the battery with it and I doubt I will. Even less of an issue if all I really need to do is keep it between 30 and 80.
I've read also that a complete discharge every once in a while is recommended but not sure how accurate that advice is.

Li's are born to die; they start degrading the moment they're assembled. Don't go too nuts, just replace them as needed.
Until I watched someone replace my N10+ battery I was very concerned. However I realized it's relatively easy with the right skillset and tools.
Mind you they say the N10+ is one of the more difficult ones to replace... meh.
Now I don't really think much about it.
