[Q] Nexus 4 Charge time

Hello Experts,
I received a new nexus 4 and noticed that it takes around 3.5 to 4 hrs for complete charging from 5% to 100%.... is it normal? my other sony xperia seems to be charge in about 1..5 hr
since i am new to Nexus 4, not sure what is the avg charge time and should i call for RMA? Please let me know what is the avg time for charging.
thx

Perfectly normal. You want a nice slow steady charge, especially in a sealed phone. The battery needs to last as long as possible. Fast charging batteries significantly reduces their lifespan. My old Nexus S takes the same amount of time to charge from 5%.. 3-4hrs or so give or take.. I still have the two year old original battery and it holds a charge just as well as it did the day I bought it. Meanwhile my 15 minute charge AA batteries I bought last year lose their charge in a week just sitting on the desk.

Mine is just about the same, but that's under use. If I don't touch the phone, it typically charges to 100% in about an hour.
And if it's through USB.. um.. more like 8 hours to fully charge.

Battery widget reborn (awesome app btw) says my phone usually charges in about 2.5 hours. This is on Qi though not sure about the regular wall charger.

2-2.5 hours for me on usb wall charger and Qi Orb.

From 2 hr 45 min (from around 12-15% juice left), my charge time has reached to 3 hr 30 mins now (i.e. from 1% juice left)... 14% juice wouldn't make such a huge difference so don't really know why it increased..

yes, this is one of the reasons i started this thread to understand what everyone is experiencing.... i called up the google customer support and they are ready to send in a RMA as it appears to be a higher side...
so let me know your thoughts guys...should 3.5 hrs charge time considered high and warrant a RMA? share your thoughts.

^ Hmmm.. I doubt if this would mean anything serious or worth RMA-ing. I can but I won't RMA my device because it's been exceptional so far. I am fairly happy with it and wouldn't want to get it replaced with a defected one.

Its perfectly normal especially from around 5% to 100%.. In my experience if you dont let it get below 20% it usually charges faster. I wouldnt RMA it especially if your phone is perfectly fine in other aspects.

I tried with a different charger yesterday and it took similar time. The charger has same voltage input levels.

You charge 3 hours, for only double the lifetime. How pathetic, actually. I didn't thought that the battery life would be that bad. I can hardly make trough 1 day, if I play some games, make some calls, and use a little bit of internet. On the last charge I got 4Hours of screen on time with 15% left.
Gosh, at least it's fun to use it. :/

[Q] How to Charge Batteries .....

I know there is already information on this topic ..... I have read conflicting advice on how to charge cell phone batteries, but I want to make sure and get the maximum use and life from the ZeroLemon 10000 Extended Battery for my Note 3 .....
The directions from the company simply state to give six full charges, but there is no explanation exactly what that means. I have sent the company a question regarding this issue, but still have not yet received an answer .....
I just finished the third full charge. When I received the battery, I charged it for 12 hours before unplugging from the charger. Then allowed my Note 3 to go completely dead (to Zero %). Then charged again for 12 hours. Did this three times so far.
I'm only getting around 37 hours of medium to heavy use, or about 1 1/2 days, and around 18-20 hours of Screen On Time, which seems somewhat impressive!
After I go through six charging cycles, should I always charge for 12 hours, or is this no longer necessary?
-- Jim

Based on what I read in charging lithium ion batteries ( which I also practice ), you don't wait until battery discharges to 0 before charging it since it shortens the life span of the battery by damaging the negative electrode. The recommendation is to charge it once it reaches 10% and don't have to fully charge battery to 100%, just around 90 - 95%. Since lithium ion batteries don't have memory effect, partial charges and discharges don't have negative effect on the overall battery life.
Didn't made this up, just quoting from memory.

Never let my stock note 3 battery go below 5 percent. I am getting great battery life. The same with my old i9100.

Turbo Charger is able to supply at least 6% of charge for at least 45minutes, then it slows down to 4% per 5minutes until it's fully charged. That last 2% charge did take a lot longer though.
Trent charger is pretty much constant at 4% per 5 minutes, then down to 3% increase after it got to 92% charged.
I'll try a 1A charger next, lol I also have a Nexus 10 charger to try as well. I dont have a 3A charger to test.

Awesome info. Just curious why you start from 5%?

That's what the phone was at at the time I thought about doing it.
it's probably an 8%-10% increase per 5mins for the first 15mins for the Turbo Charger.
i'll do another this weekend.

Hey can you update it again as mine is taking 90-100 mins to chagre with the tubro charger itself.
Thanks

How hot does the battery get when you are turbo charging it? IIRC, hotter batteries = shorter battery life overall.

what happen to 15 min 60% charge lol.
my battery gets pretty hot/warm when charging.

I think it was 6 hours of usage (overall, not 6 hours of gaming) in 15 min. And with my battery lasting 36+ hours, that 23% would def get me 6 hours.

yours is about the same. mine charged in 93mins w/ the Turbo Charger. I dont think 3-7 mins is that much of a difference.
Now that I've added a few more apps tho, it might be a lil more. I'll try time it again.

Also tried an Anker 60W 6port USB charger.
It has Power IQ where it's supposed to adjust charging power to what the device requires. I think it's supposed to max out between 2a - 2.4a
Well, from completely drained out battery, it took a full 3hrs to fully charge the device.
If you want your device charged fast, don't get this charger.
If you have time to wait and a lot of devices to charge all at once and like to travel, get this device.

Has anyone monitored the voltage/current output of their turbo charger? I cannot get to the "turbo 2" output (12 V, 1.2 A) listed on the charger. Even from 4% battery, I max out ~ 9 V, 1.5 A, which is listed as "turbo 1". In my test today, charging was pretty constant around 1.3% per minute up to 60%, then dropped off as expected. Some more data: starting at 4%, here are the total times (in minutes) to critical percentages.
10% 5
25% 16
50% 35
75% 55
90% 73

I haven't seen it use the 12V output yet. Its not s large difference 13.5 W for turbo and 14.4 W for 12V. I wonder how much faster it would charge and if it's a software or hardware limitation

Waiting for it

What app r u using to see the current output?? Ill check mine too

I personally found that the stock cable that comes with the phone doesn't allow for that much voltage/amperage to pass through it. I do have another cable at home that is thicker and it charges it a whole lot faster. I will try and get the data for it.

So what's the best cable and wall plug for fastest charging?

18 watts?
I am getting similar results as the OP. It works out to about 2400maH, which is about 75% charge in one hour. This is theoretically about the same as you would get from a 5v 2.4A (12w) amp non-turbo charger, which I have achieved with my "Note 3" 2.4A standard charger. One would think the turbo charger would charge about 50% faster on the Nexus 6 either at 9v 2A, or 12v 1.5A, which is 18w, which I haven't heard of anyone achieving.

For some reason, I don't trust those turbo chargers. I think I'll stay with a regular 2.1A charger. It doesn't charge real fast, but I have time and it may be safer for the battery.

Doubts On Turbo Charging and Battery Life on the MOTO X FORCE

Hey Folks...
I had bought the Droid turbo 2.. or MOTO X Force as known in India 2 days back.
The first time I charged the Phone - Switched it off - Connected the turbocharger ( that comes along with the Device) it took me approximately 1.30 - 2 Hours to full charge it from 5% to 100% .. It did show turbo charging on the screen.
What was strange is next instance I plugged it in at 35% it took 1 hour and charged only up to 65%. This charging was done with the phone ON unlike the first charge where I had switched it OFF. It took about 2-3 hrs to full charge the device. Though it did show turbo charging when plugging in.
I felt this was strange. I again did a charge yesterday where it took 3 hrs to charge from 27% to 65% though it showed turbo charging.
In the night I switched the device off at 28% and plugged it in.. it was fully charged in probably 1-1.10 hrs max.
Am I to understand that the phone actually turbo charges only when switched off?
I have read in a couple of places that beyond 80% it charges at the normal rate. But I noticed this slow charge way before that Threshold.
Also I get a screen ontime of roughly 4.30 to 5.30 as of now.
also I noticed that last night when I went to sleep I had switched the WIFI off and Data, But I woke upto a 8% drop in the battery.
Could you guys share your thoughts and experience with the device.
This turbo charging issue is it the device or the Charger which is at fault here? I will need to replace if any of them are at fault.
Also what is the average SOT you guys get? and does your device hit temperatures of 45 deg C?
Do help out..
Thank you in Advance.

BUMP...

Mine will turbocharge regardless if it's on or off. Start with trying another charger since it's the cheaper option.

Samsung S5e screen on time and charging

I purchased this tablet brand new maybe 6 months ago and haven't used it that much at all.
Tablet is maybe charged like 10 times total.
I noticed that Screen on time is drastically used from 9 hours when I purchased it (9 hours on wifi) to now only 6 hours (cca like 70 % of use with wifi).
So I thought that the stock charger is reducing the battery capacity because it is quick charger and charging battery with high current which I don't need.
Is it possible quick charger is the issue and making battery in worse condition?
Now I put it to charge over USB 2.0 port which is I think giving only 500 mA.
I never got 10 h of screen on time like on declaration of the tablet.
What is your SOT for this model?

My record is 11 hours using Netflix and Amazon video with 100% Wi-Fi in 48 hours of use. If it's 6 days, about 9 and a half hours. Downloading series and watching the chapters offline, it gives me 12 and a half hours with manual brightness of 70% on average. I am on android 9 and I have no intention of going up to A10 or A11 if it ever arrives. Very happy with my Tab S 5e!

Li's don't like sitting at a full charge especially in high heat. A 50% charge is much better for long idle times. Limiting the top charge to 80% and the max discharge to 20%, preferable 40% will greatly increase the life of the cell.
The capacity lose is most likely permanent.
If any swelling is noticeable replace immediately... fire hazard.

Then something is wrong with my tablet.
My total SOT is around 6 h watching youtube videos.
Is it better to do slow(normal) charge for the health of battery?
