Xperia S charging time.. - Sony Xperia S, Acro S, Ion

After update from 2.45 rooted to 2.55 rooted by OTA, my battery charging time increases from 1h45' to 2h10' to charge from 10% to full?.
I'm using ep850 charger, this is a bug of 2.55 firmware or my device has problems?.
I notice that in 2.45, it takes a long time from 98 or 99% to 100%, but in 2.55, it takes long time from 95% to 100%?
i just flashed again and wait to charge again for testing.

Yup i notice that too.
Also notices less battery drain in standby mode, but extreme power drain when screen is on (30% bright) + auto bright.

how long did you charge your phone, i've tested again, 1 h 55 minutes from 14% to full with 2.55 firm.

Same here ,I'm using this charger too(EP850).
It charges the device very fast ,but when it charged to 90% then it takes almost 25 minutes to charge until 100%.

You do know that's a design choice, right?
To keep that rhythm of charging from 0-90% all the way to 100% would reduce the battery's lifespan.

Dont worry guys I'll hit the little orange triangle with the ! in it.

[Q] Correct method for Battery charge cycle for new One X

Hi,
I keep getting multiple views when search the forum regarding CORRECT method for charging One for first few times and then after. Kindly suggest if you know for sure.
Many Thanks...
as allways: full --> empty --> full
most say two or three times is enough
Do it again when you install a new ROM or kernel

Thanks for quick reply...
don't know which thread but i remember reading about not to drain it down to zero, suggesting to charge when down to around 5%. Hence the dilemma.
Give a hint if you find it again. I haven't read it before
I'm doing as written and have a quite good (in comparison to what you are reading here) battery statistic.
Would you charge it power on or off for first few times?

You have a li-poly battery, and a lithium polymer battery doesn't need any particular charge method or charge cycle... However there's two things you can consider doing for your phone's battery.
1. Charging the phone for a full 5 hour period (even if it shows 100% charged, keep it plugged in to the end of 5 hours) and then wipe battery stat in cwm recovery if your phone doesn't detect remaining battery correctly.
2. Charging it from 50% remaining battery life is much better than letting it go all the way down to empty!
(I know lots of people told you to let the battery drains completely and then fully charge your battery, but trust me, i'm an electronic engineer, I know better, both draining the battery to 0% and charging it to full 100% are bad for your battery life, those were for ni-mh batteries not li-poly)

Exactly. No need to do full charges. Just plug it in whenever. If you are anal, then keep the charge cycling low. Eg keep the battery on a small band of charge state for example 50%-75%.

So, when the phone battery is down to 50%, we charge it.
And then when charged to a 100%, let it stay charged for an additional 5 hours, after that, or 5 hours TOTAL, from the time it is plugged in?

5 hours total, the point of this is to let your battery voltage go to it's maximum capacity (something around 4200mv, you can check the current voltage by dialing *#*#4636#*#* in your phone and going to battery information section)
And also note that full 5 hours charge cycle is just necessary when your phone doesn't detect your battery remaining percentage correctly... In normal situations just charging the phone from around 50% to almost 100% is an optimal charge method and you don't have to do the 5 hours charge...

The point you're trying to make is that for better battery life, it is important to re-charge when the battery falls to 50%, and not wait till it drops to 5-10%. Correct?
For Li-Po batteries, how low is it okay to let it go, before a re-charge?

It's better to charge your phone between 35% to 75% (optimal value is 50%) and not letting it go under 35% but after all as I said there is no need for an specific charging method and this precautions just give you something like 25% more battery life (and battery life is overall life of your phone's battery before you have to replace it, not the 100%~0% duration)

[Q]Let ARC auto turn off when 0% battery is dangerous ?

I'm a new and I don't know if let Arc from x% to 0% batterry (Ex : you are watching movies and listen to music then go to over sleep) and Arc auto turn off --> Arc will be damage ?.
With your experience, would you let me know about this
Thanks !
well from looking at one angle it might cause u serious problem..but if u have an external charger then u can charge and use your phone
dont let lithium batteries to drain till single digits..keep them charging whenever u get a chance
Maybe if you have a custom ROM, my arc s has turned off by itself from low battery and i just recharged until it was strong enough to boot into the homescreen
http://en.wikipedia.org/wiki/Lithium-ion_battery
Prolonging battery pack life
Avoid deep discharge and instead charge more often between uses, the smaller the depth of discharge, the longer the battery will last.
Avoid storing the battery in full discharged state. As the battery will self-discharge over time, its voltage will gradually lower, and when it is depleted below the low-voltage threshold (2.4 to 2.9 V/cell, depending on chemistry) it cannot be charged anymore because the protection circuit (a type of electronic fuse) disables it.
Lithium-ion batteries should be kept cool; they may be stored in a refrigerator.
The rate of degradation of Lithium-ion batteries is strongly temperature-dependent; they degrade much faster if stored or used at higher temperatures.
The rate of degradation of Lithium-ion batteries is also related to battery charge level; they degrade much faster when at 100% charge, than at lower charges. Since batteries die if deep discharged (depleted) and since a battery has some self-discharge it is frequently recommended to store batteries at 40% charge level.

I hope that tells you the answer.
if you leave it @ 0% for any extended period you run the risk of it never taking charge again. i have done this to countless (not phone) batteries by accident and i can tell you that it is 100% true.

I didn't know that tnx for sharing.This XDA is a good thing,we find some usefull stuffs here,tnx guys.

so basically, it is dangerous to leave it at both 0% and 100%?

If you let it die it may give you a hard time getting it charged again. It needs a certain amount of power to boot the phone to a state where it can check the battery and start the charger. I have killed mine a couple times and had a few tense hours trying to get it charging again. So it is best not to let the battery die completely

Thanks for your experience. But android don't have any soft auto turn off phone when battery is 10-15% ?
Besides the main battery power, there is also a reserve power when the battery is discharged. If the reserve is depleted, the battery will be completely discharged and cannot be used at all. Prolonged full discharge of the battery will shorten its working life.

Battery Charging Cycles

hello guys. i have this question in my mind, what is the best time to charge our phone? i do have XSL. at what battery percentage should we charge our phone? i want to maintain the battery health of my phone that's why i want to know what is the best time. i read that others say it must be 40%-80%, others say it must be 30%-80%.
i do charge my phone if it reaches 20% and below and charge it fully up to 100%. i also read that it is not nice to charge the phone everyday up to 100%. will someone please tell me the right way on how to charge our phone to achieve its maximum capacity and durability?
thanks!
Sony says that you can charge your battery everyday and this won't destroy your battery.
Sent from my LT26i using xda developers-app
I wrote an email to Sony support after I had problems with battery percentage reading (phone jumping from 15 to 1%) and they added recommended charging cycles.
They told me it's best to charge when the phone hits 50% if it's possible and charge up to 100, and that it's better to charge your phone when ever possible instead of waiting till the battery runs low.
Still, I connect my phone when I get home from work and it is always around 20-30% at that time and only once per day simply because I don't have time to charge my phone during the day.

Fully agreed what Vaith said.
Don't worry about charge cycles.
so i must not worry if i charge my phone when it reaches 20%? so i can charge it everyday without following any battery percentage?

A70 "Super fast charging" ! Really ?

Hi guys,
For those having the A70, does the "Super Fast Charging" feature work for you ?
With the original provided charger (with the "Super Fast Charging" logo on it), I need 3 hours to go from 9% to 100%.
So that is 1% every 2 minutes...
I do not consider this a "Super fast". I think it is "Decent" but would not go above that...
For me, this a severe disappointment... Unless of course I am doing something wrong
Anyone else can share his results for Super fast charging here ?
Regards.
Your phone must have an error. Mine lasts about 1:20 to charge from about 15% to 100%.

Hi,
Thanks a lot for your answer.
The phone... or the charger maybe ?
Is there something to enable to have that "Super Fast Charging" ?
Or something to not disable ?
If I can solve battery drain (not really lasting as I expect) and this, I will think again about keeping the phone.
So far, it's more a non keeper

Hello . Do you charge it with the screen closed? Only then fast charging works! IF yes then something is wrong with either the cable or the charger .You could also try a factory reset !

Hi,
Thanks for the info => Super Fast Charging only with display off ?
So if I leave "Always On" it will not work ?
Maybe that is why...
Anyways, I did as you suggested : I have done a full factory reset, and I have installed the bare minimum of Apps.
We will see about battery drain an battery charging.
I'll keep you posted.

Hi Sufyan3D,
Thanks a lot for that info...
I've made sure that the fast charge is enabled.
So far, the device is still at 100% so I can't say if the problem is "solved", but I'll make sure to report if now it charges as it should
And also about battery drain...

That's correct! OK check it now and tell us! No battery drain, this thing is a beast! Keep us posted!

Hi,
So far, I cannot tell about the Fast charge.
But the phone is almost idle (really gently used) with "Always on" enabled.
It's been idle since about 3hours and battery is at 98%.
I consider this a rather good result.
Hope it'll stay as it is once I install all my apps...
If not, I'll try to track the culprit for the high battery drain.
Regards.
I have same problem, after reading your post, I drained my battery to 9% and charge, it so slow while charging.

Hi guys,
Well I think it is confirmed that my phone has a problem.
The battery drain is more than acceptable.
I drove my kid to school yesterday. It is a 80 minute trip to go there and come back.
While I drove her, I used the A70 as a GPS whilst it was connected to car audio with Bluetooth.
Battery drain in 80 minutes was a little less than 10% which is quite good I think...
Then I played a bit with the phone and went to bed.
This morning it still had 84% battery.
So that is about 2% battery drain overnight.
Not stellar but acceptable.
So I decided to hook it up.
The battery panel reports "Fast charging plugged in".
But after 40 minutes, I am still at 98% charge.
That means 40 minutes to get 10% battery.
I am aware that the last 10% are the longest, but still... 40 minutes for 10% ?
I will test with another charger to see if it is the phone or the charger...
Regards.

Download a free app called "Ampere" from the Play Store, to measure your charging current. Plug the phone into the charger then open the App to get the measurements. Post your result here and compare with other A70 owners.
App shows that my charging current is around 1100mah (with the 25w charger)
I landed here as I was surprised how slow my A70 was to charge. It takes around 3 hours to get from 15% to full, using the included Samsung 3A charger & original cable. Ampere shows the current trickling in at around 850mA. Super Fast Charging is enabled. My previous phone was a Xiaomi Mi 8 Lite which charged at around 2A according to Ampere.
PS I found this link which suggests most of the fast charging happens early in the cycle https://www.sammobile.com/2019/05/02/how-fast-is-samsung-25w-super-fast-charging
The Charger is rated at max 2.77 amps and 9 volts for fast charging. It will vary through the charging cycle though. Towards the end, above 80%, the charging will slow. How long does it take from 15% to 80% and what is the measurement in the middle of that?

Samsung A70 Failed!!
I think A70 is failed in all fields.
No porper GCam. And now batteries.
My device getting charged in around 4 hours with original cable and charger.
Now I think I invest 27k in wrong item. OnePlus 7 or realme 3 pro was far better than A70.
It's just name Samsung, nothing else. Blank box with tag of Samsung. Really disappointing with this.
Sorry to fans of Samsung devices. But I don't like this. After 2011 (Samsung Galaxy Y s5360), I think Samsung is better nowadays but I was wrong. I will never buy Samsung phone again.

I am not facing such issues in my device. Regarding development, for a device like a70, development is always slow. We have the source codes available. The only thing missing is developers onboarding to support the device. If at least 1 dev puts the kernel and device source codes and tree in github, I bet development will start soon after.

I took some readings with Ampere during a charge:
0 mins 8% battery 4050mA
30 mins 38% battery 1060mA
60 mins 52% battery 1050mA
90 mins 66% battery 1020mA
120 mins 81% battery 1080mA
150 mins 91% battery 1000mA
180 mins 100% battery
So 3h from nearly empty to full which is not exactly fast. Is this in line with what others get?

Battery hold from 11% to 0%

Hi all,
occasionally I see my 7 months old Pixel 3a XL can't hold battery power from 11% down. Switches off very fast, abnormally fast. Then if I power it and start it then keeps on restarting until battery level is higher than 5-6%
I use the original charger only. Sometimes it appears, some it does not and I can see it discharges as expected.
I try to keep my battery within 40-100% full and discharge it very rarely to 0%.
Anyone facing those abnormalities? Can't think of connected events - updates, etc ....
Cheers
p.s. after last night happening again, charged the phone from 0% to 86% (phone was off during charge), turned on on 86% and left over night on the shelf. Usually drains 2-3%, this morning it dropped from 86% to 62%. All connections off, nothing unusual shown in the battery usage stats...

My 3a xl (about the same age as yours) doesn't use more than 10% max when left overnight. Are you using AOD or anything?

@Skittles9823 nothing beside stock Android and apps that I've used forever. Strange is that it's occasional - also occassional is initial drain from 100% to 92%.
Maybe its time to flash it - nothing suspicious is shown in batt stats
I use the fast charger that came with it. Not sure how it affects battery life long term. I try to keep it 100% to 40% usually and not charge it if not necessary..

I think popular wisdom is that both fast charging and in particular charging to 100% are not kind to the battery's longivety. Divided opinion about the effect of discharging to low percentages. Personally I charge to between 70 and 80% unless I know I'm going to need more capacity. 3a XL has a bigish battery, which helps. I recharge most nights but only to 70-80%. End of day I usually end up between high 40's and low 30's charge.
I manually set all apps I don't actually need to run in background to 'restricted' background use.
I charge mine up to a 100% often, when using it heavy.. I never heard of charging a battery to 100% being bad for it, unless you believe everything that is told or should I say sold to you.. Sounds like a faulty battery. If still under the 1 yr usual warranty I would have it replaced. I have drained mine down to less than 20% and still never experience any issue that OP state.

It's actually true. Lithium Ion batters degrade over time, the speed of which, depends on the amount of battery cycles they go through (0-100% and vice versa). Others have done the research and the math and found that generally a 20% to 80% and vice versa charge seems to be the best for longevity.
Personally I charge to 100 but try to charge my phone when it gets to 20-30%.

So very true my phone my money. In all my years of using cell phones, I think I have actually replaced a battery once because it went bad.
Thank you all for the links and the inputs!
One more symptom - when is very low like this morning - 1% and put it in charger - phone shuts off.
I will keep the battery in 40-80% for the future and limit the drain below 40%. I tried to charge it slow with USB - took me like 6-7 hours...
How long it takes you from zero to 100% with the stock charger - looks very fast to me - 0% to 67% in 35 mins
I personally tried to research and could not find what is worse for these batteries - number of cycles (obvious less when used below 40%) or the low capacity usage ?

Thank you all for the links and the inputs!
One more symptom - when is very low like this morning - 1% and put it in charger - phone shuts off.

The included charger is a fast charger, good for headlining how fast it charges, not so great for the battery. I just use a 'standard' (Anker) USB charger.
Jury's out on if deeper discharge is bad, but it's the number of complete cycles (0-100% counting as 1). So 40 - 80% is 0.4 of a full cycle, and you're not stressing the battery so much by taking it to 100%. Many folk here replace their phones frequently enough not to be bothered by all this - if they sell it when 20% of the battery capacity's gone, that's fine.
I've observed the behaviour and few things made me question myself...one time I can see 13% battery and palying Youtube just shutdown the phone. Put it into charger and started showing 4% as initial charge.
There was another time when using Viber video shutdown in 23% but can be overheat or software bug.
I try to keep it these days above 40% charge but still use the supplied charger till I buy new slower one.

The good news is that this phone seems to be pretty easy to repair and a battery replacement could very well be a good option for you, especially since you wouldn't be compromising any water resistance or anything
