Yet Another Battery Tip

Well... I completely stopped charging my phone with the wall charger and I am now just using either my car charger or USB and i've noticed my phone over the last two days has probably doubled in being able to hold a charge. Today I made approximately 2 or 3 30 minute - 1 hour calls, used the internet approximately 20 times for about 5 minutes each time and used SNESnoid for approximately 1 hour straight and my battery was at 40% after a 10 hour work day, not too shabby. Not to mention I also don't get that annoying 10% drop within 10 minutes of unplugging the phone anymore
I've seen a ton of other battery tip's but I've yet to see any actually say stop using a wall charger all together. Here's to hoping this helps someone

Lol thanks for the tip. I highly doubt this is anymore then a placebo but good luck to whoever tries it. Not calling you OP I am just finding it hard to believe.
Furthermore, have you tried reseting your battery stats. I mean the initial 100-90 percent drop you are calling to quick sounds like its the fault of bad battery stats. If you need a link to how to reset your battery PM me only because I might not check back to this post lol.

Hmmm... I don't think that USB/Wall would actually make a overall difference in battery life but it could be that it doesn't "idle the charging" when you hit close to a full charge. So you're probably just getting the extra 5-10% that you mentioned.

I know for a fact im getting the initial 10% but I looked at my battery today at 12:40 tonight before leaving work thinking "ahh crap I haven't charged it it's got to be at, at least 5-15% and nope, it was exactly 39%, I was amazed. Talked to a girl for about 40 minutes on my drive home, talked to another friend for 5 and battery dropped to 35%

I've noticed this as well. Days that I've only used my moto car charger, the battery (even the cheap ebay ones) seem to hold the charge better, which I thought was strange, because you would think it would be a worse -maybe equal- change.

Charges more slowly and fills up more?

That's my theory

This is the case with most batteries, and I thought it was common knowledge with Li-ion. The lower the current you charge with, the better the charge.
Using the higher amperage wall charger lets you hit the voltage peak quicker but, the topping charge will take longer. A lot of car chargers are just as high amperage as wall chargers.
Other things you can do to try maintain the capacity of the battery over the course of its life:
-NEVER let it get hot (whether from heavy usage or keeping it in a hot car or the sun)
-never deep cycle (totally kill the battery)
-try to keep it between 40 - 60% charge for most of its life (Li-ion batteries do not like being at full charge or no charge)
Doing any of these things once will not destroy the battery, but by the 500th charge cycle, you can bet your ass it will.

Sounds like my kind of job! Seriously, I use USB (through a laptop) and car chargers almost exclusively and I have no real complaints about battery life. And by that I mean it gets me through the day, which is all I've come to expect from phones for the past few years. But I did happen to use a wall charger last night, and I have JuicePlotter active, so I did some checking.
Comparing my last overnight charge using my laptop's USB to last night's charge through a wall adapter, I found that the charging was actually faster through the laptop. I see that the charge tends to drop off as it approaches 100%, so I took pairs of points from uniform sections of each plot for my comparison:
Laptop USB:
44% to 82% in 41 minutes = 0.927% / min
Wall:
63% to 91% in 37 minutes = 0.757% / min

Hah, yeah my job is pretty amazing sometimes but I have def quit using the wall charger (unless I absolutely have nothing else around)
As far as for droiddev... this is my first phone where charging it from different devices gives me different results. I don't see where it would be common sense, Li-ion batteries are not supposed to not have these memory leak/hold issues like past batteries. A charge is a charge to li-ion batteries, but not in this case.

Not sure what you mean, but you will get the most life out of your battery by charging it short spurts at a time over USB. Read the article I linked to and you will see what I mean, but you can get the best charge into your battery by slowly ramping up in steps with a low current charger.

Why does this phone take so long to charge?

I have had it plugged into the mains, running tunein radio through wifi and its gone from 85% to 86% in one hour.
If I charge from 10% with phone off it takes about 4 hours to fully charge
If I charge from 10% with my phone on running stuff, it actually never gets to fully charges by the time I finish work...at 6pm
Sorry to keep comparing to the dreaded FruitPhone, but that would charge whilst running wifi and tunein from 10% to 100% in about 2 hours.
I am beginning to think my SGS2 is faulty

i am fiding it takes about 3 hours to charge from empty . It does take a long time indeed but i guess it is what we have to do for a 1650mah battery

3 hours from empty with stock charger .
jje

it might well be a 1650 battery, but it starts to get unusable when it takes all day to charge then a few hours to loose it all.
This phone is the greatest but the battery life just completely destroys it, I am beginning to think I made the wrong choice

Aye... if I don't the bloomin thing would be dead by lunchtime, and I listen to music.
So I basically have to turn it off not use it so I can charge it, how crap is that, owned my iphone a year never had any problems with battery and I always used and charged in its dock.

The desire had slow charging too but snq- fixed this in his kernels maybe we can port his fix to our kernels
btw it's true li-ion batteries degrade quicky when the heat up (or completely charge or discharge)

From 30% it took me one hour and a half to fully charge..
I recommend to download battery mix as it takes very good statistic on the battery life and one can tell exactly how long it takes to charge and discharge

just for the record all Lion batteries in phones never fully discharge or recharge, as there balanced by a balancing chip.
when you get to the likes of 0% you actually have 20% charge, thats why you can power on the phone but it will immediately switch off again. like wise, charging you never reach 100%, it's more like 89%, again because of how Lion works.
if you fully discharged and fully recharged, well put it simply you'd have a lot of exploding phones, fire and chemical burns...

Interesting!
My phone charges in about 2,5 - 3 hours, so should be normal...
But charging with the usb cable connected to the pc it takes much longer.
Any of you experience the same thing?
greets!

Because:
a) That´s how Li-Ion-batteries are charged. To fully charge a Li-Ion-battery you need 3-4h.
b) The power-supply is pretty weak. It is just enough to charge the phone at decent speed, but it is not enough to charge it and intensely use it the same time. In this case much of the power is used by the phone and there is not enough left to do a proper charging. I use a 1,2A power-supply from my old Nokia, and while it won´t speed up charging itself, at least it slows down less when I´m using the phone while charging.

This is not possible. The mighty fruity-phone may tell you it is 100% charged, but certainly it isn´t
You can charge a Li-Ion-battery very fast from 0 to 70-85% you could reach this in 1h. But you have to charge the remaining 15-30% very slowly, otherwise the voltage would raise too much and destroy your battery.
The so called saturation-stage (the charging-stage until 100%) takes longer the faster you charged at the beginning. If you really charged until the saturation-stage in 1h, the saturation-stage will take 2-3h.
If you charge slower, so you reach saturation-stage after 2h, the saturation-stage will only take 1-2h anymore.
In the end it will always take 3-4h to fully charge a Li-Ion-cell, regardless how strong your power-supply is.
Another few notes:
Charging will get slower the fuller the battery already is.
Using the phone with low battery-percentage will lengthen the charging-time quite a bit, a stronger power-supply could help.
Getting the last 20% in a Li-Ion-cell will always be very slow, usage of the phone won´t influence this a lot, and a stronger power-supply can´t help.
It doesn´t matter much, how much charge is left in the battery, to fully charge it it will always take long, as you spend most of the time in the saturation-stage (the higher the left percentage is, the more time you spent in saturation-stage)

It is not faulty, it is designed this way.

It took 3 hours 10 minutes to fully charge my dog and bone yesterday whilst off

Your battery sounds faulty to me, taking over 4 hours and only charging 1 percent in an hour. Try the battery calibration app in the market, if it doesn't improve get it swapped mate

The wifi is the killer, try turning it off when charging your phone..
Sent from my GT-I9100 using XDA App

it takes so long to charge because samsung capped the charge current at 650 mA in the battery driver. but other phones like HTC allow charging at the full 1 amp. so that's why its a slow charge, and why its possible to drain the battery even while plugged in to the charger.

Now who wants to ask kernel developers to increase that to .850 or 1 amp and use that lol.
I believe lack of heatsink due to design is the culprit behind decision to cap it at .650.

3 hrs to fully charge, and as i use tunein radio a lot i can tell you on my device with the screen off, wifi on with tunein running, it still seems to take no more than 3 hours maybe 15 mins more at most

I am probably going to order a cheap eBay Li-Ion battery that's 1800mAH and likely has a charge cap closer to 1000mAH. I will know in a week when I finally get my phone and report back if that battery helps. I expect it to heat up while charging and am going to use an external charger.
Two replacement batteries and an external charger go for about $12 USD on eBay btw.

Nexus 10 taking more than a day to charge!!

Like the title says, my dad just bought a Nexus 10 and when he was charging it from 20%, it's taken more than an hour to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable. Is it a defective unit? I know about the Pogo charger, but I'm sure he'd rather not spend $25 on it just to find out it doesn't work.
Any suggestions or ways to fix this?
Thanks.
edit: To make things even sound worse, it only charged 2% in 1 hour and 30 minutes.

All I know is that on mine takes about 9 hours to charge with the original charger. The first time I've charged it from 16% with my Galaxy SIII cable, and it took over 14 hours.

That does seem long. I have the pogo charger and it does charge faster.
Before you buy the pogo, are you using the chargers that came with the N10? When I charge my N10 from a laptop/PC, it does charge slowly. So make sure you're charging with the correct voltage/amps.
Good luck!

I'm having a similar issue since the OTA update to 4.4.2.
I'll try changing USB cables, but I'm not optimistic. I'm tempted to try a factory reset if a different cord doesn't work.

With Wifi on, NFC off, Location set to device only, bluetooth off, screen off, using my Pogo cable I get about 22% charge per hour so from 0% to 85% is 4 hours. Whilst on Pogo if I turn brightness to full and sound full then charge is held roughly flat. I moved to Pogo from the supplied cable as when watching stuff even when connected it was discharging, so now I'm never really out of power unless I stay unplugged a long time (about 6 hours unplugged max on low brightness)

This situation happens when the tablet isn't even on, so certain settings being enabled are not the issue.
And for more info, he is using the charger that came with the tablet, so we've just decided that we'll just send it back and get a new one because the battery is obviously defective.

Have you tried a different cable/charger? AN hour to charge from 20% to 50%? Sounds about right to me. I always switch mine off when charging, I can live without when it' off. :good:

I think clearly a human error in the word chosen explains it.
Instead of "...was charging it from 20%, it's taken more than an hour to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable."
it would make more sense if written "....was charging it from 20%, it's taken more than a day to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable. "

Ahh, I see. Good call in getting it replaced. I hope you have a better experience.

here are a few points
1) the AC USB come with N10 charge up to 2A.
2) the mini USB limit to about 1A
3) if you use other mini charger, that 1A is even smaller.
4) N10 battery is HUGE comparing to all tablet out there. It will take a long time to charge
Solution: get the pogo charging cable that cost $25 (very expensive and can only use for charging), that will fully charge 2A to your tablet which should reduce the time to less than 4hrs given no other power hog apps running at the same time. It will charge slower if that power hog app running too. You can tell by how warm/hot your tablet gets when running such app.
btw, go look at the disassemble of the N10. That battle makeup most of the tablet. LOL

Agree, BUT once you get >85% the rate of charge intake drops. I can get to 85% in 3.9 hours using Pogo cable, but that last 85%-100% is slower. My battery meter sees one kink 85-90 another 90-95 and a slow crawl 95-100. As the battery is not taking up 2A >85%, all chargers, all cables, will largely take the same 85%-100% but the Pogo cable with 2A input will get you to 85% quicker.
I have moved to a dual 2.1A output PSU.

I know you revised the post but just looked at the link to the PSU you mentioned.
Note that $10 one is dual USB socket but only 2.4A total meaning if it is charging the N10 taking 2A it can only offer 0.4A to something else meaning that other thing can only be something like a phone. More importantly is the opposite if you connect a powerpack USB battery which takes say 1.5A or 2A then your Pogo cable cannot deliver its full capability.
The PSU I mentioned earlier is dual 2.1A both concurrently meaning it can charge the N10 and something else also power-hungry like charging a 2A input or 1.5A input USB battery.
There are PSUs out there which can do 4 lots of 2A concurrent, I didn't get one as they were getting chunky and personally prefer two PSUs, a 2x2A + 1A for total 5A which does my N10, my USB battery (2+2) and my phone (1) concurrently taking two power sockets.
Check the details of specifications of these devices, PSUs and batteries vary wildly.

Z5 Quick Charge

I bought an Aukey quick charger (PA-T2) and thought some people might be interested in charging speeds on a Z5 as I couldn't really find any before I bought it (the ones in the UK at least do not come with a quick charger)
Sony claims on the Z5 site that you will get "a full days charge after 45 minutes".
What I've done to test is to wait till the battery got completely to 0% and turned itself off, then just plugged in the charger with the phone remaining off. After half an hour it had charged to 32%, and at 45 minutes it had reached 53%. Not sure that would count as "a full days charge", but it's quite significant and would probably last till the end of the day if you charged mid morning.
After that I turned the phone back on and checked on Ampere the charge rate, which at 56% was 2180mA. As the battery gets more charge this slows down.
- Once it reached 60% it slowed to around 1800-1850mA
- At 65%-85% it slowed to around 1500-1600mA
- At 75% the total charging time has been 1h 12m. As you can see the first two 25%'s took 22 minutes each, but this 3rd 25% took 32 minutes.
- After 1h 25m the charge was at 85%
- Between 87 and 90% charging rate slowed to 1220mA, 1h 32min since start.
- at 95% charging is crawling along at 650mA, took 10 minutes from 90-95%
- Completed charging at 1h59m.
As I was using the phone to check the charge rates etc, I would say it could probably be finished 10 minutes quicker. Also mobile network/data and wifi were on and normal apps syncing (for the 2nd half when the phone was on) - I wanted it to be a "typical" charge time instead of one where I couldn't send/receive messages etc.
So in conclusion, quick charge works significantly better from a low charge, but for little top ups above ~75% you might not see much benefit

How long would it take for the stock charger from 0-100? If you have the time, thanks bud

from 5% to 100% it took around 2 hours and 15 minutes.
so is it really a big difference between the stock charger and the quick charger?

By the way jeremy, did you charge the Z5 from the Aukey's orange port or from one of the green ports? I don't know if there's a difference but at least they're labeled differently, the orange port having the QC logo.

I did it from the orange QC port. My Z5 didn't come with a stock charger (O2 in the UK don't give you a charger "to save the environment").
If I plug the cable into one of the non-QC ports on that same Aukey charger the max charge rate it goes at is 1310mA (at 50%) and seems to vary down and then back up from that a bit, so the QC is definitely a lot better than the standard ports.
In regards to this comment:

There is NO way my Z5 lasts 2 days. I've been using it about a week now and the battery life is probably around 80% of what I would get out of my Z3. On the Z3 before Lollipop I would very often get 2 full days, but since then it was usually about 1.5 days. On the Z5 I'd say I get about 24-30h, little over 4h screen time, but as I said I've only had it a week so I'll see if it improves as I settle with it.

Seriously? It didn't come with a charger? I'm on O2 in the UK but got it through carphonewarehouse and I got a charger

On the Z5 I'd say I get about 24-30h, little over 4h screen time, but as I said I've only had it a week so I'll see if it improves as I settle with it.

Ahem.. "Up to"
"used to say that something is less than or ​equal to but not more than a ​stated ​value, ​number, or ​level"

Umm, you are the one claiming "50% battery lasts 1 day" not me? My post referred to the claim of "one full days charge in 45 minutes". There is no "up to" there, you brought that in.

0-60 in 30 minutes?!
Qualcomm claim "In laboratory tests using a 3300mAh battery, a Quick Charge 2.0 enabled device went from 0% to 60% charge in 30 minutes"
I'm just wondering if anyone on here is actually getting this kind of result with their Quick Charger as my QC 2.0 certified charger (Tronsmart TS-WC1Q) only manages roughly 1% per minute. As the Z5 has a 2900mAh battery I was expecting even better results than the Qualcomm quoted 3300mAh charge time.
If you are getting roughly 60% charge in 30 minutes, please include your charger model and if the device was on or off during charging. Thanks!

C'mon guys, this was an easy one: 0%-60% in 30 minutes, TRUE or FALSE?
I'm trying to figure out if my Quick Chargers are working. Only quality cables used.

quick charge works normally when phone is off !

Could you be clearer please? You're saying quick charger only quick charges when the phone is off? Or it operates like a regular charger when off and only quick charges when on?
Thanks.

I mean turning off phone completely.

Read the online there are plenty of stats (infact even posted here the charge rates at different %), bigger the battery the more juice they can put in at higher charge rates for a longer period of time = more % charged. One thing you can be sure of is Qualcomm would have charged thousands of batteries and used the fastest in the advertising

Really??? People are referring to Sony's claim, read their disclaimers you will then understand where they get that figure from

You'll perhaps have to link to these disclaimers then. On their site they have the test results for the Z3 and Z3+ lasting 2 days but [not so] curiously no such evidence for the Z5, which a) does not last a day on 45 minute charge (which is what we are talking about) and b) anyway doesn't last 2 days on a full charge (which for some reason is what you are talking about).
Z5 battery life sucks compared to the Z3, yet they just continue the same claims with nothing to back them up. Look forward to your so called disclaimers and/or evidence of testing from Sony on this.

Did your Z3 last two days? I doubt it as well because most people use the phone much more than the tests. At the end of the day the phone lasts a lot longer than the competition with the same usage.
It really doesn't take long to type http://www.sonymobile.com/ go to products click sony xperia z5 and read to save you some effort I have copied the text from the page, and I will bold them to make the statements harder to miss.
What if every day had more hours?
Do more with up to two days of battery life
Xperia Z5 brings you up to two days** of ground-breaking battery power from a single charge. Listen to more music, talk for days, and stay out longer without worry. When you do need topping up, Xperia Z5 has Quick Charge capabilities to get you a full day of power in just 45 minutes.
Note the to big arse ** after the words days? - This is a disclaimer
I am sure you now get the picture and can find what these **'s mean after the word days on the Sony website, hint it's right down the bottom of the Z5 product page

So you turn off you phone each time you want to charge it?
I am not sure where you get this from??? It works with the phone on!!!
It might work faster with the phone off, but so does a normal charger

You surely are joking right? How bout you follow that ** to the bottom, and see what this disclaimer says? It shows for other models but not the Z5. "**" by itself doesn't mean "we can say things that aren't true", it means "find the ** at the bottom we'll explain it". And as literally I just said (and linked to you), it shows results for their battery claim for other models but not the Z5. Because the Z5 doesn't last 2 days, they just say it does. This is the point of this conversation. I KNOW they say it on their website, it was me that said they say it on their website (and I linked to it there too) that started this whole conversation. The point is they can't back up the claim for this model, but they can for previous ones - because those ones did last 2 days (and they have the test results to show it). And yes my Z3 would last 2 days.
Anyway, you don't really seem like having a discussion, just saying "Sony website says 2 days" over and over, so that's it from me.

The actual thread is actually about quick charge
Did you even read what I wrote, and pasted from the Sony page, the info is not on your link, it is on the Z5 product page, here I will post the whole link http://www.sonymobile.com/global-en/products/phones/xperia-z5/
Disclaimers are what they are - It is what it is, complain to them about it

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Razer Phone can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Really quick to charge, it is very nice to be able to charge for about 15 minutes and 30% added charge.

The gargantuan 4000 mAh battery charges quickly thanks to the included QC4+ charger; it doesn't get too warm while charging, with battery temps peaking around 30/36c (screen off/on) with a 23.3c room temp. That's with a case on as well.

No one else talking about charging speeds? I was looking for some in depth reviews of the QC4+ wishing my QC2.0 gs8 had it mainly for controlling heat better. Anyone else notice huge difference between the two?

Very fast. Within an hour it's almost full.

My phone stops quick charging after 25% and we'll go back to normal charging for the rest of time do any of you know what the problem could be. I am rooted and I am using magisk. So if you have any ideas let me know I have used the stock charger and wire and a combination of other Quick Charge Chargers and wires with the same result.

Phone will not deep sleep!

Yep same issue here. It takes about 1 hour 20 minutes to reach 100%
Now that is not rapid charging in my opinion.
IT also does not deep sleep at all according to accubattery discharge test whilst screen is off!

I found the culprit it was the Theme store app that comes pre-installed on the handset. Disabling this fixed the no sleep and battery drain issues for me. :0-)

I've had this thread on for quite a while now about the phone not "Quick Charging" after 25%.
https://forum.xda-developers.com/razer-phone/help/phone-quick-charging-t3709607
I've not had the phone to charge nearly full in an hour like some of you guys say, or cannot even say it charges fast at all.
I also got the post up on Razer's forums. It was posted for some time but just recently one guy responded and seems to have an argument. Cannot say I agree with his points because overall I do not believe this phone has a proper working Quick Charge 4+
https://insider.razer.com/index.php?threads/quick-charging-only-working-upto-25-battery-level.31528/
What are you guys opinions on this ?

I haven't watched mine very closely, but it does charge quick compared to my other phones, including the Moto X Pure Edition.

I recently got the Razer phone and it's a stunning phone with no problems regards to performance, but i agree with you. The 'quick charge' Is far from quick. It took around 2 hours to charge fully from 2% and also said it was rapid charging through the whole charge.
