i have nokia 7 plus and for couple of weeks i use the 1.5 amp charger ...
the screen usage of using my phone is between 4 to 5 hours use no gaming...
after that i tried the original 3 amp fast charger and the usage increase to 8 hours of use after a day recharge by orginal its come back to first 4 to 5 hours...
i scratched the cable ..in 1 direction it is not fast when i reverse it switched fast charge
i think its software issue about liying the percentage of charge and shown the 100% battery when it's 70%
i repair mobiles for 5 years and i use a lot of phones but i don't see phone like this with this battery.
comments your battery usage and send pictures...

Is it normal for the battery to take 8 hours to charge? My fascinate would take about 2, the battery on this thing drains faster than it charges! Love the phone, but is this normal?

I've noticed it takes a while to charge mine too...granted, not 8 hours. But more like 3-4, which still sucks.
Ya, I plugged mine in 3 hours ago and am only at 38%.
Check the amps on the charger. USB from the computer is usually 500mA. The charger that comes with it, and most others are 1A. If you can find a 2A charger go for it. you can get one that was for the ipad that is 2A.
My experience so far is it charges approximately 20% per hour on a Motorola 850mA wall charger. Really slow compared to my OG Droid which seemed like it would fully charge from nearly dead in about 90 minutes on the same charger.
With the wall charger I can full charge from 20% in 1 to 2 hours. I never charge more than 2 hours to get full.
USB takes longer but not that much. 3hrs maybe.
Battery Charging Issues
I do fuel cell research and we deal with rechargeable batts. There is a drawback with rapid charging it generates heat and shortens lifespan. Be very careful with exceeding the manufact. specs on amperage. I have seen packs explode and burn when current overload protection fails.
My batt life is about 8 hrs after I deep discharged/charged for a few cycles and the charge time is quicker now. My Rev stays cool unlike my flashed Omnia 910.
I will not be too surprised if LG issues a software fix.
In the dawn of the smart-phone one has to accept short battery life and deal with ac chargers, I do on a daily basis. Only so much energy can be stored in a small form battery.
Through USB, it takes me about 8-9 hours to charge, and if thats if the alarm doesn't go off on it. Bad news if it does because its either stop charging, or draining because I wake up sometimes a couple hours after a certain alarm and only have 38% battery.
Even on the wall, it takes too long to charge. The time it takes me to charge sucks.

Takes about 8hrs tops for me from dead on USB. However on the wall charger it only takes me 2 hours from dead. But i usually plug it in around 15% so really about 1hr 45min on average with the wall.
I tend to do the USB when i sleep though because as far as battery tech goes, the slower the charge the longer the battery will last(life wise, not throughout the day charge wise)
Just to give an update, my frustration level with my phone of 6 hour discharge and 8 hour charge times I decided to root, cwm, and decrapify it. Instant difference! After 1 day I put my phone on the charger at 8:30 last night with 1% battery left, it was fully charged by 10:30. Took it off of the charger at 10:30 last night and it is now 5:00 pm and I am still at 25%! This is with moderate usage, 4g on the whole time, Beautiful Widgets w/auto updating weather and location, Plume widget, Facebook widget, Youtube widget, and plenty of XDA scanning. If you haven't done so, I highly recommend the upgrades!

Just got that for Christmas as i had it on my wish list for a while, having the current battery life of OB
First impression is very good. There is extensive review on Amazon Uk which i can only agree with.
It came nearly fully charged , a good set of adapters. So far recharged twice from 50% to 100% and battery is still on 3rd mark.
Capacity is 5000mAh and even with the losses during charging should do two full recharges from 0 to 100 and a bit left.
Will do further report of performance in few days.
P.s . It was 19.98 uk pounds
http://www.amazon.co.uk/gp/aw/d/B000NDQ92W/ref=mp_s_a_5?qid=1324879765&sr=8-5
There are quite few more batteries they do up to 11000 mAh but i thought 5000 mAh should be fine.
The higher the capacity the longer the charging time fir the pack.
How much did it cost ?
Will be waiting for your experience; overall lifetime, any heating issues etc..
Price added
First drain finished , three half recharges from 50 to 100 .
Now the recharge of the unit took 6 and a half hours (factory data states 8 on 1A charger) still few cycles to get to full potential. The first recharges were on factory charge.
Also to consider there are two outlets, 500mA and 1A. Performance wise better to use the 500A as the phones battery is gonna last longer and there is gonna be more recharges accomplished before depleting the battery. Obviously when on the go one might want the 1A as being faster, but downside is more electricity loss on both sides.
Big minus - charge indicator nearly useless as it stays forever on 3 than goes just about straight to 1 .
I mean two charges from 15 to 100 and from 20 to 100 and while on 85 % of the second charge it still shows 3 lines on 90 porcent it shows 1 line and not very long after that dies.
Also the on of button is easy to press and if left on battery will become depleted .
So value for money definately is there just do not trust the indicator as it might turn you are left with hardly any back up juice.
On a final line played 3 hours games this afternoon ( Riptide and InertiaHD) , started with 12 porcent battery and now have 54. Woop woop.
Not too bad (apart from stupid charger still showing 3 lines arghhh)
P.s.
After few more cycles will try how many zero to full charges can be achieved
Thanks for sharing your experience. I am too planning to buy one now; will see if any good deal is available in local market than online deals.
Plenty of similar products on the market, best to buy something with viable feedback and reasonable capacity. After all even the best battery dies in no more than 3-4 years.
My experience is exactly as i expected, there were much more refined batteries but at way higher price and at the end all i cared for was 2+ full recharges
One more issue, i tried to charge the pack with my OB charger as it is 1A so it should be 8 hours charging time instead of 11 hours with the 500mA one i was using.
But after all night being plugged it was still charging with one light lit and the second one blinking (the blinking line is the stage of charging) .
After a check saw that the OB charger is 4.8 volts while the generic 500mA one i used initially is 5.2 volts.
Just keep that in mind in case you have issues with another battery pack. There must be enough voltage if not the charging might fail.
I'm keeping an eye on it as i have a month to return if not happy with it
Ok, final update.
I had already for two Weeks and have been charging my OB exclusively on it.
As i quotes before lg charger doesn't work, but any 5volt USB wall charger should be ok (500mA to 1A)
To be precise in the calculations i reverted to rooted stock with no running apps and no connections active. Phone charged two full times from 4-5 percent to 100 in the usual time as when on wall charger, and tHird charge gave about 20 before it switched of.
Indicators still not reliable. Until 60 percent in the second charge it showed 3 lines, than for 15 minutes showed two and when it came to 70 percent showed 1.
Blinking started about 5 minutes before it died.
So that's my rounds of the gadget.
Hope it have been useful to someone.
Now reverted to CM7 charging takes longer and even stops if i use the phone actively. But i love CM
Which of these two ways is better?
1. Use your phone to 20%~10% of battery and charge it till fully charged.
2.Frequently use and frequently charge(charge from 60% and unplugged at about 80%, then use to 50%~60% and charge again)
Which is better for the battery's life of phones and tablets,1 or 2?

If course 1 is better for the battery.

its very obvious option number 1 is good
The only thing you really need to do is break the battery in properly by fully charging/discharging 5 times when you first get it new and don't let it go dead for too long (a week) after that. You should be good.
As above, I just randomly charge my phone whenever I can/need too, and after nearly 2 years still get nearly 6 hours screen on from a charge
Will the Sony Z3c have the ability to fast charge?
It has the supported chipset 'Qualcomm Snapdragon 801'
Wonder if the moto turbo charger will work, or if Sony will bring out their own variant.
Sony's included EP880 charger outputs 1.5 amps and I've read that it provides 60 minutes of talk time from a 10 minute charge. Not sure if that's exactly quick charge but it should be faster then a regular 1 amp charger.
In the latest phonearena review (today) it says:
Sony also claims that the Z3 Compact has fast charging capabilities and can get 60 minutes of talk time from a 10 minute charge. Stay tuned for more details on charging speeds soon.

well i found this on a google search https://www.qualcomm.com/products/snapdragon/smartphones/sony-xperia-z3-compact
Nothing scientific, but I am using a Blackberry Playbook charger (1.8A output) and this thing charges FAST. I can gain like 40% charge in 30 minutes or so.
I can confirm that it charges fast. Full charge in less than 2 hours this morning.
Some days ago i charged it for 20 minutes in the morning and got 25% more juice. At the end of the day, with moderate use (taking into account that this is my new favourite toy) I had only lost 20%.
I don't know if quickcharge is available or working, but I'm more than happy with the battery and charge performance.

Yea default charger is 1.5A but it gets the job done.
So, I exchanged my explodey note 7 for a non-explodey one.
I'm now having an issue with fast charging. With the old note 7 I would leave a game running while connected to the fast charger (samsung) and would gain percent fairly quickly.
Since the exchange, the phone holds steady and gains a percent every 30 minutes or so. If I disable quick charging I begin to gain percent at a reasonable rate. Not as fast as the old note 7 with quick charging, but notably faster than with quick charge enabled.
Is anyone else experiencing this issue?
I having Problems with my phone charging. it can take up to 7 hr to fully charge when dead. @ 60 % it takes 55 min to charge just 40 %. Not sure what's going on with my new replacement phone.
They change the rates. Slow it down a bit. They dont want another battery recall. So there taking steps.
I find it that if i charge while on it take long, but off it work as my old note 7
I have the same problem .. when I'm using Viber app and charging doesn't charge I was a 48% after a 20 minutes I was at 47% so I'm really worry about it I hope is not a big problem

Yup, for me while the screen is on it charges like regular . Only after the screen is off does it fast charge and even then it's inconsistent. Had to get the coral blue instead of my black because they were out of exchanges and now this charging ish. Makes me feel like I should have kept my old one
