Wall charger and charging time

After I read several infos about this topic ...
Is that true that the Nexus S has limit of the amount of power it takes from the wall charger?
Suppose, it has limit of 750 mA.
Even if we use 1000 mA or 2000 mA, the Nexus S will take 750 mA during charging.
So, having much bigger mA charging rate will NOT speed up the charging time.
Am I correct?
Yesterday, I checked my Nexus S during wall charging:
65% charged at 01:57
87% charged at 02:48
So, it is about 22% per 50 minutes.
100% = 227 minutes (3 hours 47 minutes) ... almost 4 hours.
No task was performed, except turning on screen to check batt %.
And I was using HTC Desire charger (5v 1000 mA).
How long is yours?

Using an iPhone (1000mA) nubby it takes sometimes over four hours to charge mine

It definitely seems limited to me - though it seems that 1-2A chargers do cut 10-20% off of the charging time of the .7A stock charger. I said 30% in another thread, but further testing indicates that's not the case. Maybe the limit is around 750 or 800mA, and the stock charger doesn't really give .7 ?

if you want to charge the battery real fast
don't charge inside the phone
use a Wall charger for the battery, and it charges 100% in a little over 2 hours
the ones you find on eBay or Deal Extreme
find the ones that charges at 1000 mAh
you wont find any wall chargers for 2000 mAh (only available for cars)
the highest i've seen for wall is 1200 mAh
in my case it came in a combo so i got 2 extra batteries + wall charger

So which is the Best to buy? If you guys know of any others please post a link I don't know the charge values for the extended internal battery also.

a cheaper suggestion
Might I recommend trying something like this. 2x Battery w/ charger
I bought something similar for my Nexus one and I just rotate the batteries around using about 2 a day (including the oem one).
From my experience, the generic battery holds a bit less charge than the OEM one, but you have two + external charger so you'll always have a battery ready.
And if they are both super crappy you only wasted $10 but a potential to save $50 from the options you are looking at.
Just a suggestion but ultimately up to you. I'm probably going to purchase it right now. (o'yeah, it also took 2-3 weeks to arrive because it's form Hong Kong/China. Not sure about this seller but read the reviews before you buy)

I bought a USB power output box powered by 4AA rechargable batteries. Power box was about $7 & 4 UniRoss HyBrio cells was around $8. Charges my HD2 close to 3 charges (charging from around 10>15%, device on).
Charges all devices I have tested so far (HD2, Desire, Touch Pro, N97mini, N95)
For the money it is very good, compact & cell quality is your choice & obviously replaceable which makes this option fully serviceable unlike sealed power box options .

Best External Battery Charger
I have two portable external power solutions. The first is pre made by Energizer, holds 4 AA batteries even lithium and is for short term, low demand situations. This uses I-Go adapter tips
The second is made of several components that are easy enough to obtain. Bendix-King radio has an accessory called a clamshell, it holds 9 AA batteries and can replace the OEM battery, an enterprising firefighter created a block of aluminum that connects to the top and has a hole in it that will fit a 12-volt accessory/charger. The next item is an I-Go 12-volt charger and adapter tips for your specific device, I use the USB adapter and the charging/data cable that came with the device. Lastly you will need AA batteries. I pick up a package of 36 at Home Depot for about $15. I have used this system for a while now, most notably for 3 cross Atlantic trips (22 hours each). The last trip I watched 16 hours of movies on my HD2 and used 2 sets of batteries. This system won’t charge and run an Acer Aspire, but will charge/run a Redfly or the HTC Shift 9500. I don’t know the mAh for this, but know it will work for a long time. I use regular alkaline batteries, the lithium batteries got uncomfortably warm on larger power drains.
You can search the net for Bendix-King Clamshell (beware BK has an avionics division that is separate from the radio division). The Clamshell is even available in different colors. The I-GO is available at Radio Shack, and AA’s are available everywhere.
I have included pics for clarity…. I hope.
(I made the HD2 holder as a prototype but it is still holding up well)

I got these two items from amazon when the usb port on my phone broke. The total cost was 35$ with prime shipping. The good thing for the charger was, it can charge any standard 3.7V Li-Ion batteries, not just the HD2's battery.
PowerGen Multi-Purpose Universal Rapid Battery Charger for Use with HTC Inspire 4G , HD7 , HD2 , Surround
Htc HD2 Extended Cell Phone Battery (2400 mAh) with Battery Door

External Battery Charger
I have this same model, but my only cost 5 euros!
They are very good chargers!

I charge my hd2, or any other phone w android, using a China brand tablet I bring about. It works through USB charging though. Better than not having any battery at all.

[Q] post your power bank here..

guys.. what power bank you recommend for our Xperia SP?

I use the PNY Fancy 2600. http://www.pny.eu/product/p-24-221-701/PowerPacks/PowerPack-Fancy-2600/
Loads my SP between 50 and 60%.

I play Ingress so I use an Anker of 15.000mAh, bought for something like 33€ on Amazon. It's awesome! I recommend Anker for external batteries. They're really good

Sony 5000 but it's for my daughter

I have the portronics charge-one its a 5300mah bank.

I have a MI power bank 16000mah.

I have a sony cp-vl. It's 1400 mAh, so nothing great, but it gives me some extra juice when I really need it. Charges my sp up to 34%.

I use ASUS Zenpower 9600
its cost a little bit higher than MI Power 10500 but its 18650 cell is from LG, is better than Samsumg

if you want fast charging, i think it depend on the cable you use, not the powerbank. But im have samsung powerbank 60000mh

Im using a regular nobrand powerbank at 20000mah, it can charge my phone 2.5 times.
Price, only 20e

I'm using a Mi Powerbank 10400mAh and it's perfect for me.

TP link -> TL-PB10400 reasonable price and abilities.

Mi bank 16000mAh. Lovely

Cellular Line 2200 Mah

Mi Power Bank 16000 mAh, but I think already over Mi Power Bank 20000 mAh :fingers-crossed:

I use a laptop battery wired to a 12 volt to 5 volt DC converter (cigarette lighter to USB) and a USB cable to my phone. Tested with a Multimeter, I get 4.9 volts - 5.2 volts @ 1 amp depending on battery charge so it's safe, especially considering some mobile chargers out there go as high as 5.4 volts for a 5 volt charger. It has enough charge on the laptop battery that I charged my phone up by 31% and it used 19% of the laptop battery's charge. So 31/19*100 and it can charge the phone more than 1.5 times. Make sure you know what you're doing if you go down this path.

m using Mi Power bank 10400mAH. Its charges the device fast but also reduce the charging at same rate when on data as it has only 2.1A charging port

Intex it-pb12.5k 12500 mAh
Am using Intex it-pb12.5k 12500 mAh... So far...So good.... Torch with 3 USB Ports..

Way smaller battery or haven’t break-in the battery yet?

So I got my 5G last Thursday and have been use it alongside my XS Max (so it is not primary phone). Ran down the battery to auto shutdown and fully charge to full with phone off. I have a DROK USB Type-C Digital Multimeter (Amazon: B07448SCN6) in the line during charging so it is measure from the outside and not a phone app. The meter will auto stop counting when current draw is less than 0.1 A or 0.03 A so battery is guaranteed 100% full. The charger is an Anker 4-ports charger with IQ-something that doesn’t support quick changing on 5G so charging is limited to 5V 2.4 A max although the phone stayed below 1.2 A most of the time.
1st charge: 4:30 to charge 3790 mAh / 18.97 Wh
2nd charge: 3:35 to charge 3890 mAh / 20 Wh
Both numbers are quite below the 4500 mAh typical number on the actual battery so I test charging the 8 months old XS Max and it took 2:39 to charge 3120 mAh / 15.65 Wh. The phone turn itself on after plugging in and draw a constant 0.1 A (over 0.03 A phantom draw) after fully charging so I deducted 100 mAh from the 3120 number to 3020 mAh. That’s reasonable as XS Max’s battery is rated at 3174 mAh and losing 150 mAh after 8 months is not bad.
I’ll continue to monitor future charging to see if the number gets better but 600-700 mAh off rating is a lot. I know people in S10+ forum complaining about charging app giving them 3600-3800 mAh figures but that from an app and not an actual in-line meter. Hopefully it improves to at least 4300 mAh

I have 4235 mAh on mine based on 36 charges, it has always been around that on every charge, so definitely not 4500mAh. However the battery lasts longer than on the P30 Pro by a good amount, so I am OK with that. I would feel shortchanged if it were the reverse.

I have been using Accubattery Pro, and I believe it said initially that the phone's capacity was 4300 mAh. I manually changed its capacity to 4,500 mAh as advertised, but it's never been over 4,300 by its measurements. It's showing that its at 4277 capacity now after 34 charges. I have accidentally fallen asleep with it on the charger twice and let it charge to 100%. Every other charge session has been to 80% (+/- 2-3%). I'm a pretty heavy user, and I've only been close to powering off once at the end of the day, and that's after a charge to 80%. I've been pretty fortunate. I will say that I did not have the same success with the S10+ I had for a week or so before I returned it to pre-order the S10 5G.
